Kinds of Theory Terms modified by Theory Selected AbstractsORGANIZATIONAL PORTFOLIO THEORY: PERFORMANCE-DRIVEN ORGANIZATIONAL CHANGECONTEMPORARY ECONOMIC POLICY, Issue 4 2000L DONALDSON The article outlines some of the main ideas of a new organizational theory: organizational portfolio theory. The literature has empirically established that organizations tend not to make needed adaptive changes until they suffer a crisis of low organizational performance. Organizational portfolio theory takes this idea and constructs a theory of the conditions under which organizational performance becomes low enough for adaptive organizational change to occur. The focus is on the interaction between organizational misfit and the other causes of organizational performance. To model these interactions use is made of the concepts of risk and portfolio. [source] THE INTERACTION OF ANTISOCIAL PROPENSITY AND LIFE-COURSE VARYING PREDICTORS OF DELINQUENT BEHAVIOR: DIFFERENCES BY METHOD OF ESTIMATION AND IMPLICATIONS FOR THEORY,CRIMINOLOGY, Issue 2 2007GRAHAM C. OUSEY Recent criminological research has explored the extent to which stable propensity and life-course perspectives may be integrated to provide a more comprehensive explanation of variation in individual criminal offending. One line of these integrative efforts focuses on the ways that stable individual characteristics may interact with, or modify, the effects of life-course varying social factors. Given their consistency with the long-standing view that person,environment interactions contribute to variation in human social behavior, these theoretical integration attempts have great intuitive appeal. However, a review of past criminological research suggests that conceptual and empirical complexities have, so far, somewhat dampened the development of a coherent theoretical understanding of the nature of interaction effects between stable individual antisocial propensity and time-varying social variables. In this study, we outline and empirically assess several of the sometimes conflicting hypotheses regarding the ways that antisocial propensity moderates the influence of time-varying social factors on delinquent offending. Unlike some prior studies, however, we explicitly measure the interactive effects of stable antisocial propensity and time-varying measures of selected social variables on changes in delinquent offending. In addition, drawing on recent research that suggests that the relative ubiquity of interaction effects in past studies may be partly from the poorly suited application of linear statistical models to delinquency data, we alternatively test our interaction hypotheses using least-squares and tobit estimation frameworks. Our findings suggest that method of estimation matters, with interaction effects appearing readily in the former but not in the latter. The implications of these findings for future conceptual and empirical work on stable propensity/time-varying social variable interaction effects are discussed. [source] INDIVIDUAL STABILITY OF ANTISOCIAL BEHAVIOR FROM CHILDHOOD TO ADULTHOOD: TESTING THE STABILITY POSTULATE OF MOFFITT'S DEVELOPMENTAL THEORY,CRIMINOLOGY, Issue 3 2003ANDREA G. DONKER This paper presents a test of Moffitt's (1993) prediction on the stability of longitudinal antisocial behavior, using data from the South-Holland Study. Aggressive (overt) and non-aggressive antisocial (covert) behaviors were measured when subjects were 6,11 years old, and at follow-ups when they were 12,17 years old and 20,25 years old. In accordance with the postulate, we did find a higher level of stability of overt behavior from childhood to adulthood, compared with childhood to adolescence, especially in combination with early manifestations of status violations and/or covert behavior in childhood. Results related to the stability of covert behavior were not in accordance with the prediction, but did support the recently proposed adjustment to the starting age of the adult phase. [source] STRAIN, PERSONALITY TRAITS, AND DELINQUENCY: EXTENDING GENERAL STRAIN THEORYCRIMINOLOGY, Issue 1 2002ROBERT AGNEW Although Agnew's (1992) general strain theory (GST) has secured a fair degree of support since its introduction, researchers have had trouble explaining why some individuals are more likely than others to react to strain with delinquency. This study uses data from the National Survey of Children to address this issue. Drawing on Agnew (1997) and the psychological research on personality traits, it is predicted that juveniles high in negative emotionality and low in constraint will be more likely to react to strain with delinquency. Data support this prediction. [source] EXAMINING THE CONDITIONAL NATURE OF THE ILLICIT DRUG MARKET-HOMICIDE RELATIONSHIP: A PARTIAL TEST OF THE THEORY OF CONTINGENT CAUSATIONCRIMINOLOGY, Issue 1 2002GRAHAM C. OUSEY Recently, Zimring and Hawkins (1997) have suggested that drug markets are a "contingent cause" of the increase in homicide rates. That is, where structural conditions known to produce violence are already in place, the drug distribution-homicide link may be exacerbated. This analysis uses hierarchical linear modeling to investigate two key research questions: (1) Is within-city variation in illicit drug market activity positively associated with within-city variation in homicide rates during the 1984,1997 period? (2) Is the illicit drug market-homicide association contingent on preexisting violence conducive socioeconomic conditions? Using three measures of drug market activity, analyses provide affirmative evidence on both questions. Theoretical and research implications of these findings are discussed. [source] INTEGRATING CELERITY, IMPULSIVITY, AND EXTRALEGAL SANCTION THREATS INTO A MODEL OF GENERAL DETERRENCE: THEORY AND EVIDENCE,CRIMINOLOGY, Issue 4 2001DANIEL S. NAGIN We propose a model that integrates the extralegal consequences from conviction and impulsivity into the traditional deterrence framework. The model was tested with 252 college students, who completed a survey concerning drinking and driving. Key findings include the following: (1) Although variation in sanction certainty and severity predicted offending, variation in celerity did not; (2) the extralegal consequences from conviction appear to be at least as great a deterrent as the legal consequences; (3) the influence of sanction severity diminished with an individual's "present-orientation"; and (4) the certainty of punishment was far more robust a deterrent to offending than was the severity of punishment. [source] EXTENDING SOCIAL DISORGANIZATION THEORY: MODELING THE RELATIONSHIPS BETWEEN COHESION, DISORDER, AND FEAR,CRIMINOLOGY, Issue 2 2001FRED E. MARKOWITZ In this study, we build on recent social disorganization research, estimating models of the relationships between disorder, burglary, cohesion, and fear of crime using a sample of neighborhoods from three waves of the British Crime Survey. The results indicate that disorder has an indirect effect on burglary through fear and neighborhood cohesion. Although cohesion reduces disorder, nonrecursive models show that disorder also reduces cohesion. Part of the effect of disorder on cohesion is mediated by fear. Similar results are obtained in nonrecursive burglary models. Together, the results suggest a feedback loop in which decreases in neighborhood cohesion increase crime and disorder, increasing fear, in turn, further decreasing cohesion. [source] EXTENDING SOCIAL DISORGANIZATION THEORY: A MULTILEVEL APPROACH TO THE STUDY OF VIOLENCE AMONG PERSONS WITH MENTAL ILLNESSES,CRIMINOLOGY, Issue 4 2000ERIC SILVER Prior studies of violence among individuals with mental illnesses have focused almost exclusively on individual-level characteristics. In this study, I examine whether the structural correlates of neighborhood social disorganization also explain variation in violence. I use data on 270 psychiatric patients who were treated and discharged from an acute inpatient facility combined with tract-level data from the 1990 U.S. Census. I find that living in a socially disorganized neighborhood increased the probability of violence among the sample, an effect that was not mediated by self-reported social supports. Implications for future research in the areas of violence and mental illness are discussed. [source] BEHAVIOR GENETICS AND ANOMIE/STRAIN THEORYCRIMINOLOGY, Issue 4 2000ANTHONY WALSH Criminology is in need of conceptual revival, and behavior genetics can provide the concepts and research design to accomplish this. Behavior genetics is a biologically-friendly environmental discipline that often tells us more about environmental effects on individual traits than about genetic effects. Anomie/strain theory is used to illustrate the usefulness of behavior genetics to criminological theories. Behavior genetics examines the individual differences that sort people into different modes of adaptation and that lead them to cope constructively or destructively with strain. Behavior genetics and other biosocial perspectives have the potential to help illuminate Agnew's (1997) extension of General Strain Theory (GST) into the developmental realm. [source] FIXED REVENUE AUCTIONS: THEORY AND BEHAVIORECONOMIC INQUIRY, Issue 3 2008CARY A. DECK In this paper, we study auctions in which the revenue is fixed but the quantity is determined by the auction mechanism. Specifically, we investigate the theory and behavior of English quantity clock, Dutch quantity clock, last-quantity sealed bid, and penultimate-quantity sealed bid auctions. For theoretically equivalent fixed quantity and fixed revenue auctions, we find that fixed revenue auctions are robust to all the previously observed empirical regularities in fixed quantity auctions.

TOMBAZOS This paper serves as a short introduction to inframarginal economics. Particular emphasis is given to the historical relevance of this approach, as well as to its key feature of reconciling neoclassical questions of distribution with classical insights regarding economic organisation. [source] RATIONAL PARTISAN THEORY, UNCERTAINTY, AND SPATIAL VOTING: EVIDENCE FOR THE BANK OF ENGLAND'S MPCECONOMICS & POLITICS, Issue 2 2010ARNAB BHATTACHARJEE The transparency and openness of the monetary policy-making process at the Bank of England has provided very detailed information on both the decisions of individual members of the Monetary Policy Committee (MPC) and the information on which they are based. In this paper, we consider this decision-making process in the context of a model in which inflation forecast targeting is used, but there is heterogeneity among the members of the committee. We find that rational partisan theory can explain spatial voting behavior under forecast uncertainty about the output gap. Internally generated forecasts of output and market-generated expectations of medium-term inflation provide the best description of discrete changes in interest rates, in combination with uncertainty in the macroeconomic environment. There is also a role for developments in asset, housing and labor markets. Further, spatial voting patterns clearly differentiate between internally and externally apzpointed members of the MPC. The results have important implications for committee design and the conduct of monetary policy. [source] A THEORY OF THE INFORMAL SECTORECONOMICS & POLITICS, Issue 1 2008YOSHIAKI AZUMA In many countries, especially poor countries, a heavy burden of taxes, fees, bureaucratic hassles, and bribes drives many producers into an informal sector. This paper shows that we can attribute the existence of a large informal sector to the fact that, because productive endowments contain important unobservable components, the state cannot adjust the amounts that it extracts from producers in the formal sector finely according to each producer's endowment. Given this fact, we find that if the endowment of well-endowed producers is sufficiently large relative to poorly endowed producers, or if their number is relatively large, or if the quality of public services is sufficiently low, then the state extracts a large enough amount from producers in the formal sector that poorly endowed producers choose to work in the informal sector. This result obtains both for a proprietary state, which maximizes its own net revenue, and for a hypothetical benevolent state, which would maximize total net output. But, we also find that there exist combinations of the distribution of endowments and the quality of public services such that the policies of a proprietary state, but not the policies of a hypothetical benevolent state, would cause poorly endowed producers to work in the informal sector. [source] A NEW THEORY OF THE BUDGETARY PROCESSECONOMICS & POLITICS, Issue 1 2006SOUMAYA M. TOHAMY This paper offers an alternative to the view that budgetary decisions are incremental because they are complex, extensive, and conflicted. Our model interprets incrementalism as the result of a legislative political strategy in response to interest group politics and economic conditions. Accordingly, a legislator chooses between single-period budgeting or multiperiod budgeting, where single-period budgeting is associated with a greater chance of non-incremental budgeting outcomes. We use a statistical procedure developed by Dezhbakhsh et al. (2003) for identifying non-incremental outcomes to test the implications of the model. Results support the model's predictions: a higher discount rate and a persistently large deficit appear to cause departures from incremental budgeting; Democrats' control over the political process have a similar effect, while a higher inflation rate has an opposite effect. [source] DOES ETHICAL THEORY HAVE A PLACE IN POST-KOHLBERGIAN MORAL PSYCHOLOGY?EDUCATIONAL THEORY, Issue 2 2010Bruce Maxwell Philosophers tend to assume that theoretical frameworks in psychology suffer from conceptual confusion and that any influence that philosophy might have on psychology should be positive. Going against this grain, Dan Lapsley and Darcia Narváez attribute the Kohlbergian paradigm's current state of marginalization within psychology to Lawrence Kohlberg's use of ethical theory in his model of cognitive moral development. Post-Kohlbergian conceptions of moral psychology, they advance, should be wary of theoretical constructs derived from folk morality, refuse philosophical starting points, and seek integration with literatures in psychology, not philosophy. In this essay, Bruce Maxwell considers and rejects Lapsley and Narváez's diagnosis. The Kohlbergian paradigm's restricted conception of the moral domain is the result of a selective reading of one tendency in ethical theorizing (Kantianism). The idea that moral psychology may find shelter from normative criticism by avoiding ethics-derived models overlooks the deeper continuity between "ethical theory" and "psychological theory." The confusion and barrenness of psychology is not to be explained by calling it a "young science"; its state is not comparable with that of physics, for instance, in its beginnings. (Rather with that of certain branches of mathematics. Set theory.) For in psychology there are experimental methods and conceptual confusion. (As in the other case conceptual confusion and methods of proof.) The existence of the experimental method makes us think we have the means of solving the problems which trouble us; though problem and method pass one another by.1 [source] TOWARD A SEMIOTIC THEORY OF CHOICE AND OF LEARNINGEDUCATIONAL THEORY, Issue 3 2006Andrew Stables Such a view, Stables and Gough argue, has the potential to displace or circumvent essentially Cartesian models currently dominant within learning theory (cognitivism and responses to it) and within neoclassical economics (rational choice and responses to it). It thus enables synergies between theories of learning and of economic behavior, allowing for greater consistency in thinking about (but not necessarily prescribing for) both educational policy and provision, on the one hand, and curriculum and pedagogy, on the other. In addition, the authors claim that giving semiotics a foundational role in educational thinking provides a basis for the broader development of liberal political thought within a postmodern cultural context.

[source] DENSITY DEPENDENCE AND COOPERATION: THEORY AND A TEST WITH BACTERIAEVOLUTION, Issue 9 2009Adin Ross-Gillespie Although cooperative systems can persist in nature despite the potential for exploitation by noncooperators, it is often observed that small changes in population demography can tip the balance of selective forces for or against cooperation. Here we consider the role of population density in the context of microbial cooperation. First, we account for conflicting results from recent studies by demonstrating theoretically that: (1) for public goods cooperation, higher densities are relatively unfavorable for cooperation; (2) in contrast, for self-restraint,type cooperation, higher densities can be either favorable or unfavorable for cooperation, depending on the details of the system. We then test our predictions concerning public goods cooperation using strains of the pathogenic bacterium Pseudomonas aeruginosa that produce variable levels of a public good,iron-scavenging siderophore molecules. As predicted, we found that the relative fitness of cheats (under-producers) was greatest at higher population densities. Furthermore, as assumed by theory, we show that this occurs because cheats are better able to exploit the cooperative siderophore production of other cells when they are physically closer to them. [source] TESTS OF SEX ALLOCATION THEORY IN SIMULTANEOUSLY HERMAPHRODITIC ANIMALSEVOLUTION, Issue 6 2009Lukas Schärer Sex allocation is a crucial life-history parameter in all sexual organisms. Over the last decades a body of evolutionary theory, sex allocation theory, was developed, which has yielded capital insight into the evolution of optimal sex allocation patterns and adaptive evolution in general. Most empirical work, however, has focused on species with separate sexes. Here I review sex allocation theory for simultaneous hermaphrodites and summarize over 50 empirical studies, which have aimed at evaluating this theory in a diversity of simultaneous hermaphrodites spanning nine animal phyla. These studies have yielded considerable qualitative support for several predictions of sex allocation theory, such as a female-biased sex allocation when the number of mates is limited, and a shift toward a more male-biased sex allocation with increasing numbers of mates. In contrast, many fundamental assumptions, such as the trade-off between male and female allocation, and numerous predictions, such as brooding limiting the returns from female allocation, are still poorly supported. Measuring sex allocation in simultaneously hermaphroditic animals remains experimentally demanding, which renders evaluation of more quantitative predictions a challenging task. I identify the main questions that need to be addressed and point to promising avenues for future research. [source] TOWARD A SELECTION THEORY OF MOLECULAR EVOLUTIONEVOLUTION, Issue 2 2008Matthew W. Hahn First page of article [source] A TEST OF WORKER POLICING THEORY IN AN ADVANCED EUSOCIAL WASP, VESPULA RUFAEVOLUTION, Issue 6 2005T. Wenseleers Abstract Mutual policing is an important mechanism for maintaining social harmony in group-living organisms. In some ants, bees, and wasps, workers police male eggs laid by other workers in order to maintain the reproductive primacy of the queen. Kin selection theory predicts that multiple mating by the queen is one factor that can selectively favor worker policing. This is because when the queen is mated to multiple males, workers are more closely related to queen's sons than to the sons of other workers. Here we provide an additional test of worker policing theory in Vespinae wasps. We show that the yellowjacket Vespula rufa is characterized by low mating frequency, and that a significant percentage of the males are workers' sons. This supports theoretical predictions for paternities below 2, and contrasts with other Vespula species, in which paternities are higher and few or no adult males are worker produced, probably due to worker policing, which has been shown in one species, Vespula vulgaris. Behavioral observations support the hypothesis that V. rufa has much reduced worker policing compared to other Vespula. In addition, a significant proportion of worker-laid eggs were policed by the queen. [source] ACCUMULATING DOBZHANSKY-MULLER INCOMPATIBILITIES: RECONCILING THEORY AND DATAEVOLUTION, Issue 6 2004John J. Welch Abstract Theoretical models of the accumulation of Dobzhansky-Muller incompatibilities (DMIs) are studied, and in particular, the framework introduced by Orr (1995) and a verbal model introduced by Kondrashov et al. (2002). These models embody very different assumptions about the relationship between the substitution process underlying evolutionary divergence and the formation of incompatibilities. These differences have implications for our ability to make inferences about the divergence from patterns in the relevant data. With this in mind, the models are investigated for their ability to account for three patterns evident in this data: (1) the asymmetrical nature of incompatibilities under reciprocal introgression; (2) the finding that multiple concurrent introgressions may be necessary for an incompatibility to form; and (3) the finding that the probability of obtaining an incompatibility by introgressing a single amino acid remains roughly constant over a wide range of genetic distances. None of the models available in the literature can account for all of the empirical patterns. However, modified versions of the models can do so. Ways of discriminating between the different models are then discussed. [source] PERFORMANCE MANAGEMENT AND BEST VALUE AUDIT IN SCOTLAND: A RESEARCH NOTE ON THEORY AND PRACTICEFINANCIAL ACCOUNTABILITY & MANAGEMENT, Issue 4 2008Arthur Midwinter This paper appraises the theory and practice of Best Value Audit in Scotland, and in particular the central assumption that a robust performance management system is essential for continuous improvement in service delivery, within a rational planning model of governance. The reviews of Best Value Audit in practice reveal important gaps between theory and practice, with an overemphasis on monitoring process rather than performance. There is, therefore, considerable scope to reduce the demands of the audit process on local government, and Best Value Audit, needs to move from a theoretical model to an evidence-based model of good practice if real progress is to be made. [source] THREE VISIONS OF HISTORY AND THEORYHISTORY AND THEORY, Issue 2 2007Charles Tilly First page of article [source] ON FINANCE AS A THEORY OF TFP, CROSS-INDUSTRY PRODUCTIVITY DIFFERENCES, AND ECONOMIC RENTS,INTERNATIONAL ECONOMIC REVIEW, Issue 2 2008Andrés Erosa We develop a theory of capital-market imperfections to study how the ability to enforce contracts affects resource allocation across entrepreneurs of different productivities, and across industries with different needs for external financing. The theory implies that countries with a poor ability to enforce contracts are characterized by the use of inefficient technologies, low aggregate TFP, large differences in labor productivity across industries, and large employment shares in industries with low productivity. These implications are supported by the empirical evidence. The theory also suggests that entrepreneurs have a vested interest in maintaining a status quo with low enforcement. [source] GOVERNMENT-MANDATED DISCRIMINATORY POLICIES: THEORY AND EVIDENCE,INTERNATIONAL ECONOMIC REVIEW, Issue 2 2006Hanming Fang We study an economy with private and public sectors in which workers invest in imperfectly observable skills that are important to the private sector but not to the public sector. Government regulation allows native majority workers to be employed in the public sector with positive probability while excluding the minority from it. We show that even when the public sector offers the highest wage rate, it is still possible that the discriminated group is, on average, economically more successful. The widening Chinese/Malay wage gap in Malaysia since the adoption of its New Economic Policy in 1970 supports our model. [source] A THEORY OF MONEY AND MARKETPLACES*INTERNATIONAL ECONOMIC REVIEW, Issue 1 2005Akihiko Matsui This article considers an infinitely repeated economy with divisible fiat money. The economy has many marketplaces that agents choose to visit. In each marketplace, agents are randomly matched to trade goods. There exist a variety of stationary equilibria. In some equilibrium, each good is traded at a single price, whereas in another, every good is traded at two different prices. There is a continuum of such equilibria, which differ from each other in price and welfare levels. However, it is shown that only the efficient single-price equilibrium is evolutionarily stable.
