Infrastructure and Rural Development: US and EU Perspectives Infrastruktur und Entwicklung des ländlichen Raums: Perspektiven aus den USA und der EU Infrastructures et développement rural : Perspectives aux États-Unis et dans l'Union européenne

EUROCHOICES, Issue 1 2008
David Blandford
Infrastructure and Rural Development: US and EU Perspectives Infrastructural development remains a cornerstone of rural development policy in both the United States and Europe. It is evident that rural development objectives differ, but similar policy measures are used. The economic rationale for infrastructure development centres on efficiency and creation of competitive advantage. Policy intervention is justified because of the added costs of infrastructure provision in remote, sparsely populated areas. Although this policy focus does not guarantee success, regions leading in economic development typically have better physical infrastructure. In the United States, policy must adapt to challenges posed by an ageing rural infrastructure and demographic change that will increase demands on social infrastructure such as housing and health facilities. There will be greater local responsibility for funding, and expanded use of public/private partnerships. In the European Union, the major challenge is in redirecting resources to new member states, where there is urgent need for both large new investments in transport networks and small investments to improve local access. Although two current options for funding these diverse needs focus on European policies only, investments in non-farm physical capital and public infrastructure cannot be sustained without active national policies to complement the European efforts, perhaps through co-financing requirements. Infrastructures et développement rural : Perspectives aux États-Unis et dans l'Union européenne Le développement des infrastructures demeure un pilier de la politique de développement rural aux États-Unis comme dans l'Union européenne. Les objectifs de développement rural diffèrent bien évidemment mais des mesures semblables sont employées. La justification économique du développement des infrastructures repose sur l'efficience et la création d'avantages concurrentiels. L'intervention publique est justifiée par les coûts supplémentaires des infrastructures dans les zones éloignées à population clairsemée. Bien que ce type de politique ne garantisse pas le succès, les régions en avance de développement économique ont en général de meilleures infrastructures physiques. Aux États-Unis, la politique soit s'adapter aux défis que posent le vieillissement des infrastructures rurales et l'évolution démographique qui va augmenter la demande d'infrastructures sociales telles que les services de santé et de logement. La responsabilité du financement local va augmenter et les partenariats public/privé vont se développer. Dans l'Union européenne, le principal défi est de réorienter les ressources vers les nouveaux pays membres qui ont un besoin urgent de nouveaux investissement d'ampleur dans les réseaux de transport et d'investissement de plus faible ampleur dans l'amélioration des accès locaux. Deux options actuelles de financement de ces divers besoins se concentrent sur les seules politiques européennes, mais les investissements dans le capital physique non agricole et dans les infrastructures publiques ne peuvent pas se poursuivre sans des politiques nationales actives complémentant les efforts fournis au niveau européen, peut-être à travers des mécanismes de co-financement. Infrastruktur und Entwicklung des ländlichen Raums: Perspektiven aus den USA und der EU Bei der Entwicklung der Infrastruktur handelt es sich nach wie vor sowohl in den USA als auch in Europa um einen Eckpfeiler in der Politik zur Entwicklung des ländlichen Raums. Es ist offensichtlich, dass sich die Ziele bei der Entwicklung des ländlichen Raums unterscheiden, die Politikmaßnahmen ähneln sich jedoch. Die wirtschaftliche Begründung für die Entwicklung der Infrastruktur zielt auf die Effizienz und das Schaffen von Wettbewerbsvorteilen ab. Politikeingriffe sind gerechtfertigt, da die Bereitstellung von Infrastruktur in entlegenen, dünn besiedelten Gebieten höhere Kosten verursacht. Obgleich dieser Schwerpunkt der Politik den Erfolg noch nicht garantiert, verfügen die wirtschaftlich am weitesten entwickelten Regionen typischerweise über eine bessere physische Infrastruktur. In den USA muss sich die Politik an die Herausforderungen anpassen, welche eine in die Jahre gekommene Infrastruktur im ländlichen Raum und der demografische Wandel mit sich bringen, und wodurch neue Anforderungen an die soziale Infrastruktur, wie z.B. Wohnungsbau und Gesundheitseinrichtungen, gestellt werden. Bei der Finanzierung werden die Kommunen stärker in die Verantwortung genommen, und öffentlich-private Partnerschaften werden an Bedeutung gewinnen. In der EU besteht die größte Herausforderung darin, Ressourcen zu den neuen Mitgliedstaaten umzuverteilen, wo sowohl neue Großinvestitionen in die Transportnetzwerke als auch kleinere Investitionen zur Verbesserung des lokalen Zugangs dringend benötigt werden. Obwohl sich die beiden im Moment vorhandenen Optionen zur Finanzierung dieser vielfältigen Bedürfnisse ausschließlich auf europäische Politikmaßnahmen konzentrieren, können die Investitionen in außerlandwirtschaftliches physisches Kapital und in die öffentliche Infrastruktur nicht ohne wirksame Politikmaßnahmen auf nationaler Ebene (z.B. die Pflicht zur Kofinanzierung) als Ergänzung zu den Bemühungen auf europäischer Ebene aufrecht erhalten werden.

Advancement of renewables in Bangladesh and Thailand: Policy intervention and institutional settings

NATURAL RESOURCES FORUM, Issue 3 2006
Sk Noim Uddin
Abstract This article reviews and analyses the advancement of renewable sources of energy in Bangladesh and Thailand in terms of policy intervention and institutional settings. Since renewable forms of energy emit far smaller amounts of greenhouse gas compared with fossil fuels, their use should mitigate climate change impacts while contributing to the provision of energy services. The article turns first to a review of energy,environment trends and the potential for renewables in these two nations. It then discusses strategies for the advancement of renewables. It is argued that further significant efforts can be made towards the advancement of renewables in Bangladesh and Thailand. These two nations could also learn from the experience in industrialized nations and other developing nations with regard to requisite policy instruments and processes. A number of barriers remain to the advancement of renewables, especially in terms of policy arrangements, institutional settings, financing mechanisms and technologies. Resources, cooperation and learning are required in order to overcome such barriers and to foster the development of necessary policy measures. Implementation of the clean development mechanism (CDM) under the Kyoto Protocol, and replication and adaptation of effective strategies from other settings are possible avenues for this. [source]

Policy interventions to reduce the harm from smoking

ADDICTION, Issue 1s1 2000
Peter Anderson
The other papers in this series on reduced smoking discuss interventions focused on individuals. This paper illustrates possible smoking reduction interventions focused on policies rather than individuals. Target 12 of the new WHO Health For All Policy aims to significantly reduce the harm from addictive substances, including tobacco, in all member states by 2015, and the WHO Third Action Plan for Tobacco-Free Europe focuses on reducing the harm from tobacco. These documents recommend five key policy strategies: market regulation, product liability, smoke-free environments, support for smoking cessation and education, public information and public opinion. Interventions such as price increases, restricting availability, advertising bans and product control could all be used to achieve harm reduction. Research on reducing the harm of smoking needs to include policy as well as treatment research. [source]

Identification in Nonseparable Models

ECONOMETRICA, Issue 5 2003
Andrew Chesher
Weak nonparametric restrictions are developed, sufficient to identify the values of derivatives of structural functions in which latent random variables are nonseparable. These derivatives can exhibit stochastic variation. In a microeconometric context this allows the impact of a policy intervention, as measured by the value of a structural derivative, to vary across people who are identical as measured by covariates. When the restrictions are satisfied quantiles of the distribution of a policy impact across people can be identified. The identification restrictions are local in the sense that they are specific to the values of the covariates and the specific quantiles of latent variables at which identification is sought. The conditions do not include the commonly required independence of latent variables and covariates. They include local versions of the classical rank and order conditions and local quantile insensitivity conditions. Values of structural derivatives are identified by functionals of quantile regression functions and can be estimated using the same functionals applied to estimated quantile regression functions.

Pareto-Improving Redistribution and Pure Public Goods

GERMAN ECONOMIC REVIEW, Issue 2 2000
Richard Cornes
In the pure public good model, the Nash equilibrium associated with one initial income distribution may Pareto dominate the equilibrium associated with another distribution of the same aggregate income. We explore this possibility and examine its implications for Pareto-improving policy intervention by undertaking a comparative static analysis of Pareto-improving tax-financed increases in pure public good provision. Under some circumstances, a government can engineer policies that raise public good provision while increasing the well-being of contributors and non-contributors. Crucial factors promoting this outcome involve a large number of non-contributors, a high marginal valuation for the public good by non-contributors and a large aggregate response of contributors to changes in their income.

Measuring health inequality with realization of potential life years (RePLY)

HEALTH ECONOMICS, Issue S1 2009
Kam Ki Tang
Abstract This paper proposes a new method to measure health inequalities that are caused by conditions amenable to policy intervention. The method is built on a technique that can separate avoidable and unavoidable mortality risks, using world mortality data compiled by the World Health Organization for the year 2000. The new method is applied to data from 191 countries. It is found that controlling for unavoidable mortality risks leads to a lower estimate of health inequality than otherwise, especially for developed countries. Furthermore, although countries with a higher life expectancy at birth tend to have lower health inequality, there are significant variations in health inequalities across countries with the same life expectancy. The results therefore support the WHO's plea for using health inequality as a distinct parameter from the average level of health in assessing the performance of health systems.

Economic Impacts of Technology, Population Growth And Soil Erosion At Watershed Level: The Case Of the Ginchi in Ethiopia

JOURNAL OF AGRICULTURAL ECONOMICS, Issue 3 2004
B.N. Okumu
A dynamic bio-economic model is used to show that, without technological and policy intervention, soil loss levels, income and nutrition could not be substantially or sustainably improved in a highland area of Ethiopia. Although cash incomes could rise by more than 40% over a twelve-year planning period, average per ha soil losses could be as high as 31 tonnes per ha. With the adoption of an integrated package of new technologies, however, results show the possibility of an average two-and-a-half-fold increase in cash incomes and a 28% decline in aggregate erosion levels even with a population growth rate of 2.3%. Moreover, a minimum daily calorie intake of 2000 per adult equivalent could be met from on-farm production with no significant increases in erosion. However, higher rates of growth in nutritional requirements and population introduce significant strains on the watershed system. From a policy perspective, there is a need for a more secure land tenure policy than currently prevailing to facilitate uptake of the new technology package, and a shift from the current livestock management strategy to one that encourages livestock keeping as a commercial enterprise. It would also imply a shift to a more site-specific approach to land management. [source]

How close is close enough?

JOURNAL OF POLICY ANALYSIS AND MANAGEMENT, Issue 3 2007
Evaluating propensity score matching using data from a class size reduction experiment
In recent years, propensity score matching (PSM) has gained attention as a potential method for estimating the impact of public policy programs in the absence of experimental evaluations. In this study, we evaluate the usefulness of PSM for estimating the impact of a program change in an educational context (Tennessee's Student Teacher Achievement Ratio Project [Project STAR]). Because Tennessee's Project STAR experiment involved an effective random assignment procedure, the experimental results from this policy intervention can be used as a benchmark, to which we compare the impact estimates produced using propensity score matching methods. We use several different methods to assess these nonexperimental estimates of the impact of the program. We try to determine "how close is close enough," putting greatest emphasis on the question: Would the nonexperimental estimate have led to the wrong decision when compared to the experimental estimate of the program? We find that propensity score methods perform poorly with respect to measuring the impact of a reduction in class size on achievement test scores. We conclude that further research is needed before policymakers rely on PSM as an evaluation tool. © 2007 by the Association for Public Policy Analysis and Management [source]

Property-Led Redevelopment in Post-Reform China: A Case Study of Xintiandi Redevelopment Project in Shanghai

JOURNAL OF URBAN AFFAIRS, Issue 1 2005
Shenjing He
Government-backed redevelopment has been replaced by privately funded and property-led redevelopment. This article discerns the impetus of ongoing property-led redevelopment. A case study of the Xintiandi project in Shanghai reveals how property-led redevelopment actually works. Pro-growth coalitions between local government and developers are formed. Despite its role as capital provider, the private sector is still regulated by the government due to its negligible influence on local governance. The government controls the direction and pace of urban redevelopment through policy intervention, financial leverages, and governance of land leasing. Property-led redevelopment is driven by diverse motivations of different levels of the government, e.g. transforming urban land use functions, showing off the entrepreneurial capability of local government, and maximizing negotiated land benefits. Driven by profit seeking, some thriving urban neighborhoods are displaced by high-value property development, and suffer from uneven redevelopment. [source]

Schooling and Labor Market Impacts of a Natural Policy Experiment

LABOUR, Issue 4 2005
Harry Patrinos
These estimates apply to a subgroup of individuals, in the spirit of the local average treatment effect (LATE) literature. Returns to schooling estimates that apply to a subgroup of individuals affected by the policy intervention may be more interesting from a policy perspective than the return to the ,average' individual. We use an instrument based on the 1980 education reform (the Organic Law of Education), which provided for 9 years of compulsory basic education. Alternative estimates derived from interacting the education reform with father's education are also obtained. The estimates are consistent with recent findings suggesting that the effect of education, at least for certain subgroups affected by policy intervention, is as large as or larger than what is suggested by ordinary least squares estimates.

Environmental leapfrogging in developing countries: A critical assessment and reconstruction

NATURAL RESOURCES FORUM, Issue 3 2003
Richard Perkins
It has been suggested in recent years that developing countries need not pass through the dirty stages of industrial growth that marred the past of today's developed countries. Instead, they may be able to bypass these by leapfrogging straight to modern, clean technologies as an integral part of capacity addition. This article critically reviews existing approaches to leapfrogging. It argues that they are not only characterized by considerable ambiguity, but also based on an incomplete understanding of the technological and policy requirements of cleaner industrialization. Consequently, the article goes on to offer a number of suggestions as to how current approaches might be advanced so as to better meet the challenge of leapfrogging. Amongst these suggestions is greater clarification of the specific targets for leapfrogging and policy intervention to accelerate the development of technological capabilities needed to select, absorb and innovate leapfrog technologies.

Prepartum Work, Job Characteristics, and Risk of Cesarean Delivery

BIRTH, Issue 1 2002
Shirley Hung MPP
Background:,Reducing the rate of cesarean deliveries in the United States is a high priority among public health officials and members of the medical community. Many factors known to contribute to an individual woman's risk of having a cesarean rather than a vaginal delivery are not readily altered by public policy intervention. In this study we explored the effects on type of delivery of prepartum work practices, a category of factors that has a potential to affect the likelihood of cesarean delivery and to be amenable to change. Methods:,Data are from U.S. Food and Drug Administration's Infant Feeding Practices Study, using questions on mail surveys administered prenatally and at 1 month postpartum. The sample comprised 1194 women who worked during pregnancy. The outcome measure is type of delivery. Predictor variables are characteristics of prepartum work: how far into their pregnancy the women work, number of hours worked, and occupation. Results:,For most women, maintaining employment through the third trimester, working long hours, and working in certain occupations are not independently associated with the odds of having a cesarean delivery. However, we found marginally significant evidence that those women who worked more than 40 hours a week in a sales job were more likely to have cesarean deliveries than women who worked in other occupations. Conversely, women working part-time in sales jobs were less likely to have a cesarean delivery. Conclusion:,This study provides evidence that prenatal work does not substantially increase the probability of having a cesarean delivery in most occupational categories.

Zhongxiu Zhao
F14; L52; L63 Abstract China has become the biggest exporter of electronic products in the world. Government policy intervention has contributed significantly to the rapid expansion of the electronics industry. The present paper examines the evolutionary development of industrial policies related to the electronics industry in China and the impacts of such policies on the shaping of the industry. In particular, the relationship between foreign funded enterprises and domestic firms are examined in detail. The future trend of the industry is also discussed in the paper, and the policy focus of the Chinese Government is predicted. [source]

Guidelines for Systematic Review in Conservation and Environmental Management

CONSERVATION BIOLOGY, Issue 6 2006
ANDREW S. PULLIN
política de la conservación; práctica de la conservación; toma de decisiones; transferencia de conocimiento basado en evidencia Abstract:,An increasing number of applied disciplines are utilizing evidence-based frameworks to review and disseminate the effectiveness of management and policy interventions. The rationale is that increased accessibility of the best available evidence will provide a more efficient and less biased platform for decision making. We argue that there are significant benefits for conservation in using such a framework, but the scientific community needs to undertake and disseminate more systematic reviews before the full benefit can be realized. We devised a set of guidelines for undertaking formalized systematic review, based on a health services model. The guideline stages include planning and conducting a review, including protocol formation, search strategy, data inclusion, data extraction, and analysis. Review dissemination is addressed in terms of current developments and future plans for a Web-based open-access library. By the use of case studies we highlight critical modifications to guidelines for protocol formulation, data-quality assessment, data extraction, and data synthesis for conservation and environmental management. Ecological data presented significant but soluble challenges for the systematic review process, particularly in terms of the quantity, accessibility, and diverse quality of available data. In the field of conservation and environmental management there needs to be further engagement of scientists and practitioners to develop and take ownership of an evidence-based framework. Resumen:,Un mayor número de disciplinas está utilizando marcos de referencia basados en evidencias para revisar y diseminar la efectividad de las intervenciones de gestión y política. El fundamento es que la mayor accesibilidad de la evidencia mejor disponible proporcionará una plataforma de toma de decisiones menos sesgada y más eficiente. Argumentamos que hay beneficios significativos para la conservación al utilizar tal marco de referencia, pero la comunidad científica debe emprender y diseminar revisiones más sistemáticas antes de que se pueda comprender el beneficio completo. Diseñamos un conjunto de directrices para realizar revisiones sistemáticas formales, basado en un modelo de servicios de salud. Las etapas de las directrices incluyen la planificación y conducción de una revisión, incluyendo formación del protocolo, estrategias de búsqueda, inclusión de datos, extracción y análisis de datos. La diseminación de revisiones es abordada en términos del desarrollo actual y los planes futuros para una biblioteca de acceso abierto en la Web. Al utilizar estudios de caso resaltamos modificaciones críticas a las directrices para la formulación del protocolo, evaluación de la calidad de los datos, extracción de datos y síntesis de datos para la gestión ambiental y de conservación. Los datos ecológicos presentaron retos significativos, pero solucionables, para el proceso de revisión sistemática, particularmente en términos de la cantidad, accesibilidad y calidad de los datos disponibles. Se requiere un mayor compromiso de científicos y profesionales de la gestión ambiental y de conservación para desarrollar y apropiarse de un marco de referencia basado en evidencias. [source]

DESTINATION EFFECTS: RESIDENTIAL MOBILITY AND TRAJECTORIES OF ADOLESCENT VIOLENCE IN A STRATIFIED METROPOLIS,

CRIMINOLOGY, Issue 3 2010
PATRICK SHARKEY
Two landmark policy interventions to improve the lives of youth through neighborhood mobility,the Gautreaux program in Chicago and the Moving to Opportunity (MTO) experiments in five cities,have produced conflicting results and have created a puzzle with broad implications: Do residential moves between neighborhoods increase or decrease violence, or both? To address this question, we analyze data from a subsample of adolescents ages 9,12 years from the Project on Human Development in Chicago Neighborhoods, a longitudinal study of children and their families that began in Chicago,the site of the original Gautreaux program and one of the MTO experiments. We propose a dynamic modeling strategy to separate the effects of residential moving across three waves of the study from dimensions of neighborhood change and metropolitan location. The results reveal countervailing effects of mobility on trajectories of violence; whereas neighborhood moves within Chicago lead to an increased risk of violence, moves outside the city reduce violent offending and exposure to violence. The gap in violence between movers within and outside Chicago is explained not only by the racial and economic composition of the destination neighborhoods but also by the quality of school contexts, adolescents' perceived control over their new environment, and fear. These findings highlight the need to simultaneously consider residential mobility, mechanisms of neighborhood change, and the wider geography of structural opportunity. [source]

Advancing a Political Ecology of Global Environmental Discourses

DEVELOPMENT AND CHANGE, Issue 4 2001
W. Neil Adger
In the past decade international and national environmental policy and action have been dominated by issues generally defined as global environmental problems. In this article, we identify the major discourses associated with four global environmental issues: deforestation, desertification, biodiversity use and climate change. These discourses are analysed in terms of their messages, narrative structures and policy prescriptions. We find striking parallels in the nature and structure of the discourses and in their illegibility at the local scale. In each of the four areas there is a global environmental management discourse representing a technocentric worldview by which blueprints based on external policy interventions can solve global environmental dilemmas. Each issue also has a contrasting populist discourse that portrays local actors as victims of external interventions bringing about degradation and exploitation. The managerial discourses dominate in all four issues, but important inputs are also supplied to political decisions from populist discourses. There are, in addition, heterodox ideas and denial claims in each of these areas, to a greater or lesser extent, in which the existence or severity of the environmental problem are questioned. We present evidence from location-specific research which does not fit easily with the dominant managerialist nor with the populist discourses. The research shows that policy-making institutions are distanced from the resource users and that local scale environmental management moves with a distinct dynamic and experiences alternative manifestations of environmental change and livelihood imperatives.

Prospects and Challenges for Growth and Poverty Reduction in Asia

DEVELOPMENT POLICY REVIEW, Issue 2006
John Humphrey
The extent of poverty reduction in Asia by 2015 will depend upon two linked issues: sustaining the current rates of economic growth and avoiding increases in income inequality. Rapid growth over the past 15 years has itself created three challenges for its continuation: inadequate infrastructure; energy shortages and insecurity; and depletion of natural resources and environmental degradation. The ways in which these problems are addressed will have impacts not only on growth but also on inequality, requiring policy interventions at multiple levels, having implications for governance at multiple levels, and involving the development of new partnerships within the region and beyond.

The Costly Business of Trust

DEVELOPMENT POLICY REVIEW, Issue 3 2004
Mark Cosson
This article provides a framework for analysing trust-based projects which can be used as a diagnostic tool to design more effective policy interventions, particularly addressing the problem of meeting users' needs for which many microfinance schemes have come under criticism. Two microfinance projects in Mexico are used to illustrate how a system of trust is built, the role of trust-brokers, and the policy of subsidising trust-building projects. The aim is to provide a tool capable of identifying crucial actors in trust systems and the nature of the linkages between them, so that trust can be effectively operationalised to improve projects' effectiveness and suitability to local conditions.

Ten years after the United Nations General Assembly Special Session (UNGASS): assessing drug problems, policies and reform proposals

ADDICTION, Issue 4 2009
Peter Reuter
ABSTRACT In 1998 the United Nations General Assembly Special Session resolved that governments would reduce drug production and consumption greatly within 10 years. With that period now elapsed, there is an interest in reviewing how successful this was and considering how drug policy could be improved. The demand for drugs in the world has stabilized mainly as a result of the interaction of epidemic forces, culture and economic development. Supply has become more concentrated and the menu of drugs has changed surprisingly slowly. Drug policy is shifting to a more explicitly tolerant configuration in Europe and a few other countries, but retains its ferocity in most of the world. The most prominent innovations under discussion have limited potential effects (heroin maintenance), have as yet been unproductive of policy interventions (,addiction is a brain disease') or have no political appeal (legalization). The option with the most scope is increased effort at diverting arrested drug users out of criminal justice systems. No prevention, treatment or enforcement strategies have demonstrated an ability to substantially affect the extent of drug use and addiction. The best that government interventions can do is to reduce the damaging consequences of drug use and drug control. More attention should be given to reductions in the intensity of drug enforcement, which has many unintended adverse consequences and yields few of the claimed gains. [source]

Aggregate time-series regression in the field of alcohol

ADDICTION, Issue 7 2001
Jürgen Rehm
Time-series regression of successive aggregate data has been used widely to explore relationships between substance use and harm, or to measure effects of policy interventions. This paper suggests minimal standards to conduct such analyses with respect to validity and reliability of underlying data, statistical techniques and requirements and interpretation of results.

Cost,benefit analysis involving addictive goods: contingent valuation to estimate willingness-to-pay for smoking cessation

HEALTH ECONOMICS, Issue 2 2009
David L. Weimer
Abstract The valuation of changes in consumption of addictive goods resulting from policy interventions presents a challenge for cost,benefit analysts. Consumer surplus losses from reduced consumption of addictive goods that are measured relative to market demand schedules overestimate the social cost of cessation interventions. This article seeks to show that consumer surplus losses measured using a non-addicted demand schedule provide a better assessment of social cost. Specifically, (1) it develops an addiction model that permits an estimate of the smoker's compensating variation for the elimination of addiction; (2) it employs a contingent valuation survey of current smokers to estimate their willingness-to-pay (WTP) for a treatment that would eliminate addiction; (3) it uses the estimate of WTP from the survey to calculate the fraction of consumer surplus that should be viewed as consumer value; and (4) it provides an estimate of this fraction. The exercise suggests that, as a tentative first and rough rule-of-thumb, only about 75% of the loss of the conventionally measured consumer surplus should be counted as social cost for policies that reduce the consumption of cigarettes. Additional research to estimate this important rule-of-thumb is desirable to address the various caveats relevant to this study. Copyright © 2008 John Wiley & Sons, Ltd. [source]

The Effects of Health Sector Market Factors and Vulnerable Group Membership on Access to Alcohol, Drug, and Mental Health Care

HEALTH SERVICES RESEARCH, Issue 3p1 2007
Susan E. Stockdale
Objective. This study adapts Andersen's Behavioral Model to determine if health sector market conditions affect vulnerable subgroups' use of alcohol, drug, and mental health services (ADM) differently than the general population, focusing specifically on community-level predisposing and enabling characteristics. Data Sources. Wave 2 data (2000,2001) from the Health Care for Communities study, supplemented with cases from wave 1 (1997,1998), were merged with area characteristics taken from Census, Area Resource File (ARF), and other data sources. Study Design. The study used four-level hierarchical logistic regression to examine access to ADM care from any provider and specialty ADM access. Interactions between community-level predisposing and enabling vulnerability characteristics with individual race/ethnicity, age, income category, and insurance type were explored. Principal Findings. Nonwhites, the poor, uninsured, and elderly had lower likelihoods of service use, but interactions between race/ethnicity, income, age and insurance status with community-level vulnerability factors were not statistically significant for any service use. For ADM specialty care, those with Medicare, Medicaid, private fully managed, and private partially managed insurance, the likelihood of utilization was higher in areas with higher HMO penetration. However, for those with other insurance or no insurance plan, the likelihood of utilization was lower in areas with higher HMO penetration. Conclusions. Community-level enabling factors explain part of the effect of disadvantaged status but, with the exception of the effect of HMO penetration on the relationship between insurance and specialty care use, do not modify any of the residual individual-level effects of disadvantage. Interventions targeting both structural and individual levels may be necessary to address the problem of health disparities. More research with longitudinal data is necessary to sort out the causal direction of social context and ADM access outcomes, and whether policy interventions to change health sector market conditions can shift ADM treatment utilization.

Worker voice, managerial response and labour productivity: an empirical investigation

INDUSTRIAL RELATIONS JOURNAL, Issue 5 2006
Alex Bryson
ABSTRACT This article investigates the relationship between worker voice practices, employee perceptions of managerial responsiveness and labour productivity. It argues that managerial responsiveness is a critical but under-investigated variable in the study of the relationship between worker voice, human resource management and performance. Our results suggest that managerial responsiveness to worker voice does lead to superior labour productivity. However, this relationship is only found in non-union workplaces and there is little relationship between formal voice regime and productivity. One important implication of this finding is that more responsive management will result in improved productivity, so policy interventions should focus on how to motivate managers to become more responsive to their employees.

Discrete policy interventions and rational forecast errors in foreign exchange markets: the uncovered interest parity hypothesis revisited

INTERNATIONAL JOURNAL OF FINANCE & ECONOMICS, Issue 4 2002
Dimitris G. Kirikos
Abstract This paper combines policy response explanations of the uncovered interest parity puzzle with a time series approach that accounts for discrete central bank interventions. When monetary authorities manage the interest rate differential through an anti-inflationary policy rule, which allows for discrete shifts, then a stochastic segmented trends representation seems appropriate for the exchange rate and the interest rate differential series. In this setting, rational forecast errors are possible, and a test of the uncovered parity hypothesis, based on the cross-equation restrictions on a Markov switching process, suggests that the parity relationship cannot be rejected for three European currencies vis-à-vis the US dollar.

Nursing Home Characteristics and Potentially Preventable Hospitalizations of Long-Stay Residents

JOURNAL OF AMERICAN GERIATRICS SOCIETY, Issue 10 2004
Orna Intrator PhD
Objectives: To examine the association between having a nurse practitioner/physician assistant (NP/PA) on staff, other nursing home (NH) characteristics, and the rate of potentially preventable/avoidable hospitalizations of long-stay residents, as defined using a list of ambulatory care,sensitive (ACS) diagnoses. Design: Cross-sectional prospective study using Minimum Data Set (MDS) assessments, Centers for Medicare and Medicaid Services inpatient claims and eligibility records, On-line Survey Certification Automated Records, (OSCAR) and Area Resource File (ARP). Setting: Freestanding urban NHs in Maine, Kansas, New York, and South Dakota. Participants: Residents of 663 facilities with a quarterly or annual MDS assessment in the 2nd quarter of 1997, who had a prior MDS assessment at least 160 days before, and who were not health maintenance organization members throughout 1997 (N=54,631). Measurements: A 180-day multinomial outcome was defined as having any hospitalization with primary ACS diagnosis, otherwise having been hospitalized, otherwise died, and otherwise remained in the facility. Results: Multilevel models show that facilities with NP/PAs were associated with lower hospitalization rates for ACS conditions (adjusted odds ratio (AOR)=0.83), but not with other hospitalizations. Facilities with more physicians were associated with higher ACS hospitalizations (ACS, AOR=1.14, and non-ACS, AOR=1.10). Facilities providing intravenous therapy, and those that operate a nurses' aide training program were associated with fewer hospitalizations of both types. Conclusion: Employment of NP/PAs in NHs, the provision of intravenous therapy, and the operation of certified nurse assistant training programs appear to reduce ACS hospitalizations, and may be feasible cost-saving policy interventions.

Prescription Duration After Drug Copay Changes in Older People: Methodological Aspects

JOURNAL OF AMERICAN GERIATRICS SOCIETY, Issue 3 2002
Sebastian Schneeweiss MD
OBJECTIVES: Impact assessment of drug benefits policies is a growing field of research that is increasingly relevant to healthcare planning for older people. Some cost-containment policies are thought to increase noncompliance. This paper examines mechanisms that can produce spurious reductions in drug utilization measures after drug policy changes when relying on pharmacy dispensing data. Reference pricing, a copayment for expensive medications above a fixed limit, for angiotensin-converting enzyme (ACE) inhibitors in older British Columbia residents, is used as a case example. DESIGN: Time series of 36 months of individual claims data. Longitudinal data analysis, adjusting for autoregressive data. SETTING: Pharmacare, the drug benefits program covering all patients aged 65 and older in the province of British Columbia, Canada. PARTICIPANTS: All noninstitutionalized Pharmacare beneficiaries aged 65 and older who used ACE inhibitors between 1995 and 1997 (N = 119,074). INTERVENTION: The introduction of reference drug pricing for ACE inhibitors for patients aged 65 and older. MEASUREMENTS: Timing and quantity of drug use from a claims database. RESULTS: We observed a transitional sharp decline of 11%± a standard error of 3% (P = .02) in the overall utilization rate of all ACE inhibitors after the policy implementation; five months later, utilization rates had increased, but remained under the predicted prepolicy trend. Coinciding with the sharp decrease, we observed a reduction in prescription duration by 31% in patients switching to no-cost drugs. This reduction may be attributed to increased monitoring for intolerance or treatment failure in switchers, which in turn led to a spurious reduction in total drug utilization. We ruled out the extension of medication use over the prescribed duration through reduced daily doses (prescription stretching) by a quantity-adjusted analysis of prescription duration. CONCLUSION: The analysis of prescription duration after drug policy interventions may provide alternative explanations to apparent short-term reductions in drug utilization and adds important insights to time trend analyses of drug utilization data in the evaluation of drug benefit policy changes.

Drivers of ecosystem change and their impacts on human well-being in Lake Victoria basin

Abstract To offer an increased understanding of the spatial patterns, temporal, social and physical predictors of the conversion and transformations of land use in Lake Victoria basin, an assessment of proximate and underlying forces is presented. This study discusses key theoretical underpinnings for the manifold linkages existing between selected drivers of land-use changes around the basin and their consequences on human well-being. Using a meta-analytical research design, the paper analyses ecosystems level cases of the causes of land use and cover changes in the basin, to determine any spatio-temporal or institutional patterns and dynamics. A suite of recurrent core variables has been identified to influence land use and cover changes in the basin. The most prominent of these at the underlying category are climatic factors, economic factors, institutions, national and regional policies, population growth and other remote influences. At the proximate level, these factors drive cropland expansion, overgrazing, infrastructure extension and rates of land degradation. These are supported by empirical evidence from the basin. This assessment is crucial for appropriate local and transboundary policy interventions, which have to be fine-tuned to the locale-specific dynamic patterns associated with the inherent ecosystems changes.
