Value and exchange in law and economics: Buchanan versus posner

Meir Kohn’s Exchange and Value claims that economics can be organised around two opposed paradigms, the exchange and the value paradigms. In this paper, we apply this dichotomy to characterize the analyses proposed by economists in the field known as “law and economics”. We compare and contrasts the perspectives proposed by two prominent scholars—James Buchanan and Richard Posner—and argue that they, respectively, represent the exchange and the value paradigm in law and economics. More precisely, we show that Buchanan sticks to a definition of economics based on the exchange paradigm, and this leads him to define law and economics in a rather specific, different, narrower than Posner’s way to define law and economics—a definition that corresponds to a conception of economics based on the value paradigm.     

Destabilization effect of international trade in a perfect foresight dynamic general equilibrium model

In the present paper, we consider a two-country, two-good, two-factor general equilibrium model with CIES nonlinear preferences, asymmetric technologies across countries and decreasing returns to scale. It is shown that aggregate instability and endogenous fluctuations may occur due to international trade. In particular, we prove that the integration into a common market on which countries trade the produced good and the capital input may lead to period-two cycles even when the closed-economy equilibrium is saddle-point stable in both countries.     

Asymmetry in Price Transmission in Agricultural Markets

This paper explores the asymmetries in price transmission from international to local markets. We expect the presence of large intermediaries in agricultural markets to lead to a stronger price transmission when international prices decline than when they rise. The empirical evidence confirms the presence of asymmetric price transmission consistent with the presence of large intermediaries with monopsony power.     

COMMUNITY MEMBERSHIP ASPIRATIONS: THE LINK BETWEEN INEQUALITY AND REDISTRIBUTION REVISITED*

This article studies how distributional tensions can act in many different ways depending on the social affinity between the different economic classes and their prospect of upward or downward mobility. We consider that socioeconomic group membership through its implied social interactions and peer effects is an important determinant of an individual's outcome. Agents, while voting on a social contract, take into account the consequences of their choice over their ex post belonging to a particular community. Thus, the endogenous sorting of the population into clusters may lead to a nonmonotonic relationship between inequality and the pressure for redistributive policies.     

Does organizational culture play a role in the development of psychological distress?

The aim of this article is to analyze the extent to which organizational culture contributes to the symptoms of psychological distress in the workforce. Integrating organizational culture and work organization conditions makes it possible to examine how culture is associated with the various components of work organization conditions, and how these conditions might relate to symptoms of psychological distress in employees. Data from the SALVEO study were collected in 2009–2012 from a sample of 1824 individuals nested in 60 Canadian workplaces. Multilevel regression models were used to analyze the data. After controlling for individual and family characteristics, only group and rational cultures were associated with psychological distress, but both type of organization cultures were mediated by work organization conditions. Group culture is indirectly associated with lower levels of psychological distress since it favors lower levels of psychological demands and job insecurity. Rational culture is indirectly associated with higher levels of psychological distress because it favors higher psychological demand levels. The results obtained highlighted the importance of including variables relating to broader organizational context in models examining stress in the workplace.     

A multidimensional spatial lag panel data model with spatial moving average nested random effects errors

This paper focuses on a three-dimensional model that combines two different types of spatial interaction effects, i.e. endogenous interaction effects via a spatial lag on the dependent variable and interaction effects among the disturbances via a spatial moving average (SMA) nested random effects errors. A three-stage procedure is proposed to estimate the parameters. In a first stage, the spatial lag panel data model is estimated using an instrumental variable (IV) estimator. In a second stage, a generalized moments (GM) approach is developed to estimate the SMA parameter and the variance components of the disturbance process using IV residuals from the first stage. In a third stage, to purge the equation of the specific structure of the disturbances a Cochrane–Orcutt-type transformation is applied combined with the IV principle. This leads to the GM spatial IV estimator and the regression parameter estimates. Monte Carlo simulations show that our estimators are not very different in terms of root mean square error from those produced by maximum likelihood. The approach is applied to European Union regional employment data for regions nested within countries.     

Bargaining over an uncertain outcome:¶the role of beliefs

We study the Nash bargaining solution of a problem in which two agents bargain over an uncertain outcome. Under the assumptions of risk neutrality and of constant absolute risk aversion, we study the way that the solution varies, ex ante, when we vary the beliefs of one agent. Changing an agent's beliefs in a way that makes them “more distant” from the other agent's beliefs makes the second agent better off. Received: 10 May 2001 / Accepted: 22 August 2001     

Falling Wage Shares in Europe and the United States: How Important is Aggregation Bias?

This paper sheds light on the importance of aggregation bias in the analysis of wage shares developments over time and across countries. We focus on five European countries and the United States and show that the trend decline in the aggregate wage share observed in these countries over much of the 1980s and 1990s partly reflects changes in the sectoral composition of the economy. The application of a fixed-weight aggregation method changes the profile of the observed wage share in a significant way: in particular there is no longer sign of an overshooting of the wage share levels of the early-1970s. Error-correction wage equations based on the adjusted wage shares generally have a better regression fit and show long-run elasticities of real wages to unemployment that vary less across countries and are substantially lower than those obtained with observed shares.     

Protecting software development projects against underestimation

When a project in progress has been seriously underestimated, it is essential to figure out how much additional effort is required to complete it within its original scope and delivery date. This article posits that project contingencies should be based on the amount it will take to recover from the underestimation, and not on the amount that would have been required had the project been adequately planned from the beginning, and that these funds should be administered at the portfolio level. A model to calculate the required funds is developed.     

INEQUALITY OF OPPORTUNITIES VS. INEQUALITY OF OUTCOMES: ARE WESTERN SOCIETIES ALL ALIKE?

This paper analyzes the relationship between income inequality and inequality of opportunities for income acquisition in nine developed countries during the 1990s. Equality of opportunity is defined as the situation where income distributions conditional on social origin cannot be ranked according to stochastic dominance criteria. We measure social origin by parental education and occupation and use the database built by Roemer et al. (2003 ). Stochastic dominance is assessed using nonparametric statistical tests. Our results indicate strong disparities in the degree of equality of opportunity across countries and a strong correlation between inequality of outcomes and inequality of opportunity. The U.S. and Italy show up as the most unequal countries in terms of both outcome and opportunity. At the opposite extreme, income distributions conditional on social origin are almost the same in Scandinavian countries even before any redistributive policy. We complement the ordinal comparison by resorting to an original scalar “Gini” index of opportunities, which can be decomposed into a risk and a return component. In our sample, inequality of opportunity is mostly driven by differences in mean income conditional on social origin, and differences in risk compensate the return element in most countries.
