The Transformation Problem : an Aleternative Solution with an Identical Aggregate Profit Rate in the Labor value and the Monetary Space.

The aim of this paper is to demonstrate that, even if Marx's solution to the transformation problem can be modified, his basic conclusions remain valid. the proposed alternative solution which is presented hare is based on the constraint of a common general profit rate in both spaces and a money wage level which will be determined simultaneously with prices.

Reported Job Satisfaction : What Does It Mean?

By reporting his satisfaction with his job or any other experience, an individual does not communicate the number of utils that he feels. Instead, he expresses his posterior preference over available alternatives conditional on acquired knowledge of the past. This new interpretation of reported job satisfaction restores the power of microeconomic theory without denying the essential role of discrepancies between one’s situation and available opportunities. Posterior human wealth discrepancies are found to be the best predictor of reported job satisfaction. Static models of relative utility and other subjective well-being assumptions are all unambiguously rejected by the data, as well as an \"economic\" model in which job satisfaction is a measure of posterior human wealth. The \"posterior choice\" model readily explains why so many people usually report themselves as happy or satisfied, why both younger and older age groups are insensitive to current earning discrepancies, and why the past weighs more heavily than the present and the future.

Heterodox Inflation Stabilization in Argentina, Brazil, and Israel. A Historical Review and Some Stylized Facts

This article presents a review of the stabilization attempts in Argentina, Brazil, and Israel during the 1980’s. Earlier research is summarized and complemented with additional sources of contemporaneous information and a detailed analysis of institutional features. The examination of these episodes underscores the strong economic and empirical relationship between the governments’ fiscal policy and the rate of inflation.

Rigidité normale, dévaluation et équilibre général intertemporel

La présente étude analyse les effets dynamiques de la dévaluation du franc CFA, à l’aide d’un modèle monétaire d’équilibre général, intertemporel et multisectoriel. L’accent est particulièrement mis sur les interactions entre dévaluation et accumulation du capital. Dans le modèle, les effets du changement de parité passent par le marché du travail qui se caractérise par l’inertie du salaire nominal. Les résultats montrent que la dévaluation relance l’investissement, avec des effets expansionnistes sur l’activité économique. Le choc monétaire n’a eu qu’un impact limité sur les soldes budgétaire et commercial. Une mesure d’accompagnement telle que la réduction des salaires de la fonction publique améliore ces deux soldes mais déclenche un processus récessif.

Political Influence, Economic Interests and Endogenous Tax Structure in a Computable Equilibrium Framework: with Applicatioon to the United States, 1973 and 1983

A full understanding of public affairs requires the ability to distinguish between the policies that voters would like the government to adopt, and the influence that different voters or group of voters actually exert in the democratic process. We consider the properties of a computable equilibrium model of a competitive political economy in which the economic interests of groups of voters and their effective influence on equilibrium policy outcomes can be explicitly distinguished and computed. The model incorporates an amended version of the GEMTAP tax model, and is calibrated to data for the United States for 1973 and 1983. Emphasis is placed on how the aggregation of GEMTAP households into groups within which economic and political behaviour is assumed homogeneous affects the numerical representation of interests and influence for representative members of each group. Experiments with the model suggest that the changes in both interests and influence are important parts of the story behind the evolution of U.S. tax policy in the decade after 1973.

Wage Flexibility and Contract Structure in Germany

In this paper, we look at how labor market conditions at different points during the tenure of individuals with firms are correlated with current earnings. Using data on individuals from the German Socioeconomic Panel for the 1985-1994 period, we find that both the contemporaneous unemployment rate and prior values of the unemployment rate are significantly correlated with current earnings, contrary to results for the American labor market. Estimated elasticities vary between 9 and 15 percent for the elasticity of earnings with respect to current unemployment rates, and between 6 and 10 percent with respect to unemployment rates at the start of current firm tenure. Moreover, whereas local unemployment rates determine levels of earnings, national rates influence contemporaneous variations in earnings. We interpret this result as evidence that German unions do, in fact, bargain over wages and employment, but that models of individualistic contracts, such as the implicit contract model, may explain some of the observed wage drift and longer-term wage movements reasonably well. Furthermore, we explore the heterogeneity of contracts over a variety of worker and job characteristics. In particular, we find evidence that contracts differ across firm size and worker type. Workers of large firms are remarkably more insulated from the job market than workers for any other type of firm, indicating the importance of internal job markets.

Sector-Specific on-the-Job Training: Evidence from U.S. Data.

Using data from the National Longitudinal Survey of Youth (NLSY), we re-examine the effect of formal on-the-job training on mobility patterns of young American workers. By employing parametric duration models, we evaluate the economic impact of training on productive time with an employer. Confirming previous studies, we find a positive and statistically significant impact of formal on-the-job training on tenure with the employer providing the training. However, the expected net duration of the time spent in the training program is generally not significantly increased. We proceed to document and analyze intra-sectoral and cross-sectoral mobility patterns in order to infer whether training provides firm-specific, industry-specific, or general human capital. The econometric analysis rejects a sequential model of job separation in favor of a competing risks specification. We find significant evidence for the industry-specificity of training. The probability of sectoral mobility upon job separation decreases with training received in the current industry, whether with the last employer or previous employers, and employment attachment increases with on-the-job training. These results are robust to a number of variations on the base model.

Explaining the Great Divergence: Medium and Message on the Eurasian Land Mass, 1700-1850

Between 1700 and 1850, per-capita income doubled in Europe while falling in the rest of Eurasia. Neither geography nor economic institutions can explain this sudden divergence. Here the consequences of differences in communications technology are examined. For the first time, there appeared in Europe a combination of a standardized medium (national vernaculars with a phonetic alphabet) and a non-standardized message (competing religious, political and scientific ideas). The result was an unprecedented fall in the cost of combining ideas and burst of productivity-raising innovation. Elsewhere, decreasing standardization of the medium and increasing standardization of the message blocked innovation.

Au-delà de l'instrumentalisation: une nouvelle identité pour le tiers secteur en France?

Ce mémoire porte sur la constitution du tiers secteur français en tant qu’acteur social et politique. Dans de nombreux pays, les relations entre l’État et les organismes mutualistes, coopératifs et associatifs de la société civile (un ensemble hétérogène qu’on appelle ici le « tiers secteur ») ont été récemment formalisées par des partenariats. En France, cette institutionnalisation s’est concrétisée en 2001 par la signature d’une Charte (CPCA). Nous explorons l’hypothèse qu’à travers l’institutionnalisation, le tiers secteur français se construit en tant qu’acteur –ayant une (ou des) identités propres de même qu’un projet de société relativement bien défini. La perspective dominante présente dans la littérature internationale traitant de l’institutionnalisation des rapports entre l’État et le tiers secteur est celle d’une instrumentalisation des organisations du tiers secteur au détriment de leurs spécificités et de leur autonomie. Cette perspective nous semble limitative, car elle semble être aveugle à la capacité d’action des organisations. Par conséquent, dans ce mémoire, nous cherchons à comprendre si une transformation identitaire a eu lieu ou est en cours, au sein du tiers secteur français, et donc s’il se transforme en acteur collectif. Pour apporter certains éléments de réponse à nos hypothèses et questions de recherche, nous avons effectué une analyse des discours via deux sources de données; des textes de réflexion rédigés par des acteurs clés du tiers secteur français et des entretiens effectués avec certains d’entre eux au printemps 2003 et à l’automne 2005. Sur la base de deux inspirations théoriques (Hobson et Lindholm, 1997 et Melucci, 1991), notre analyse a été effectuée en deux étapes. Une première phase nous a permis d’identifier deux cadres cognitifs à partir desquels se définissent les acteurs du tiers secteur français, les cadres « association » et « économie solidaire ». Une deuxième phase d’analyse consistait à déterminer si les deux cadres cognitifs pouvaient être considérés comme étant des tensions existant au sein d’un seul et même acteur collectif. Nos résultats nous permettent de conclure que les organisations du tiers secteur français ne se perçoivent pas globalement comme un ensemble unifié. Néanmoins, nous avons pu dégager certains éléments qui démontrent que les cadres sont partiellement conciliables. Cette conciliation est grandement subordonnée aux contextes sociopolitiques et économiques français, européen et international et est également conditionnelle à la découverte d’un mode de fonctionnement convenant à tous les acteurs.
