Cross-section Data (cross-section + data)
Selected AbstractsWhat to Do about Missing Values in Time-Series Cross-Section DataAMERICAN JOURNAL OF POLITICAL SCIENCE, Issue 2 2010James Honaker Applications of modern methods for analyzing data with missing values, based primarily on multiple imputation, have in the last half-decade become common in American politics and political behavior. Scholars in this subset of political science have thus increasingly avoided the biases and inefficiencies caused by ad hoc methods like listwise deletion and best guess imputation. However, researchers in much of comparative politics and international relations, and others with similar data, have been unable to do the same because the best available imputation methods work poorly with the time-series cross-section data structures common in these fields. We attempt to rectify this situation with three related developments. First, we build a multiple imputation model that allows smooth time trends, shifts across cross-sectional units, and correlations over time and space, resulting in far more accurate imputations. Second, we enable analysts to incorporate knowledge from area studies experts via priors on individual missing cell values, rather than on difficult-to-interpret model parameters. Third, because these tasks could not be accomplished within existing imputation algorithms, in that they cannot handle as many variables as needed even in the simpler cross-sectional data for which they were designed, we also develop a new algorithm that substantially expands the range of computationally feasible data types and sizes for which multiple imputation can be used. These developments also make it possible to implement the methods introduced here in freely available open source software that is considerably more reliable than existing algorithms. [source] Risk preference and employment contract typeJOURNAL OF THE ROYAL STATISTICAL SOCIETY: SERIES A (STATISTICS IN SOCIETY), Issue 4 2006Sarah Brown Summary., We explore the possibility that a systematic relationship exists between employment within a particular type of contract and risk preference. We exploit a set of proxies for risk preference, whereby some of the proxies capture risk loving behaviour (expenditure on gambling, smoking and alcohol) whereas others capture risk averse behaviour (expenditure on life and contents insurance, and unearned income). The empirical analysis, based on pooled cross-section data from the UK Family Expenditure Survey, 1997,2000, provides evidence of a systematic relationship between employment contract type and risk preference, with, for example, self-employed workers being more or less likely to engage in the consumption of ,risky' or financial security products respectively. The results are based on the ordered generalized extreme value model, a relatively infrequently used discrete choice model, which allows for ordering and correlation in the alternatives observed. [source] Die Vorteile des Staatsmonopols in der Gebäudeversicherung: Erfahrungen aus Deutschland und der SchweizPERSPEKTIVEN DER WIRTSCHAFTSPOLITIK, Issue 1 2001Thomas Von Ungern-Sternberg This paper compares the prices charged and the quality of service provided by state monopolies and private insurance companies on the property insurance market. Both the cross-section data from Switzerland and the time-series evidence from Germany strongly suggest that in this specific market the presence of state monopolies is very advantageous for the customers. This raises the question why German academic economists made practically no effort to defend their state insurance monopolies in the debate about the 3rd EU directive on property insurance. Is it possible that peer pressure prevents academic economists from standing up to defend state monopolies, even if these are clearly to the benefit of consumers? [source] Vulnerability to Poverty in Papua New Guinea in 1996ASIAN ECONOMIC JOURNAL, Issue 3 2010Raghbendra Jha C21; C23; C26; I32 This paper uses cross-section data from the 1996 Papua New Guinea Household Survey to assess household vulnerability to poverty in Papua New Guinea. Vulnerability varies across regions, household size, gender and level of education of households. We use a simple empirical model that permits estimation of vulnerability to poverty assuming that households have the same conditional distribution of consumption in a stationary environment. Although this approach does not capture all dimensions of vulnerability, it at least raises the policy interest that vulnerability should be considered alongside poverty. [source] Political manipulation in a majoritarian democracy: central government targeting of public funds to English subnational government, in space and across timeBRITISH JOURNAL OF POLITICS & INTERNATIONAL RELATIONS, Issue 3 2001Peter John This article argues that it is rational for the executive to target resources in space and through time if it seeks to maximise its chances of electoral success. In majoritarian democracies such as the United Kingdom, there are particularly strong incentives to target resources to marginal legislative constituencies, although similar opportunies exist in other political systems. The benefits of such a practice could be growing, because the costs of forms of temporal targeting predicted by theories of the political business cycle have increased, owing to the effect of the global economy. In the United Kingdom one channel through which resources can be targeted is central grants to local authorities. This model is tested with pooled cross-section data on the central finance of English local government between 1981/1982,1995/1996. The article confirms that central government spatially targeted marginals after 1988/1989 while it continued to allocate greater funds near national elections, conditional on its opinion-poll ratings. Hypotheses from the literature on distributional politics are also tested, finding evidence for the temporal allocation of resources to win local elections. [source] Relationship between environmental performance and financial performance: an empirical analysis of japanese corporationsBUSINESS STRATEGY AND THE ENVIRONMENT, Issue 2 2007Yuriko Nakao Abstract The hypotheses that a firm's environmental performance has a positive impact on its financial performance and vice versa are statistically supported by Japanese data. However, this tendency for two-way positive interaction appears to be only a relatively recent phenomenon. The tendency for realizing the two-way interaction is not limited to the top-scoring firms in terms of both financial and environmental performance. On the contrary, this is also a trend that can be observed fairly generally. Obviously, when we consider only scores of those companies that published the relevant information in their environmental reports, and conduct the statistical causality test with such information as additional input to the pooled time-series and cross-section data of financial performance, the results become more strongly significant. From the recent experience of environmental policies in Japan, we infer that information-based environmental policy measures are effective to encourage the ongoing transition toward a more sustainable market economy.
