Mankind at the Starting Point

The most striking feature of the current economic situation in Spain is the huge unemployment rate, above 25 percent. From an orthodox perspective, we suggest that this unemployment is the result of a highly inflexible labor market, which needs to be reformed by introducing flexibility measures. The paper argues, however, that labor market reforms introduced since the early 1980s, allowing an excessive use of temporary employment contracts, have had perverse effects on the Spanish economy. They have affected negatively not only aggregate demand and supply, but also income distribution. The emergence of these market reforms helps explain the current rate of unemployment as well as the deep impact of the global financial crisis on overall Spanish economic activity.     

A Comparison of Ex Post and Ex Ante Measures of Producers' Surplus in Estimating the Returns to Canadian Federal Sheep Research

The returns to Canadian federal sheep research expenditures between 1968 and 1984 are estimated using the economic surplus approach. Ex post and ex ante measures of the change in producers' surplus are compared. Regression analysis is used to estimate the lag structure of the effects of research on the national supply function, facilitating the estimation of returns on average and at the margin. The effect of the excess burden of tax collection on returns to sheep research is investigated. The internal rate of return to sheep research has been about 25% at the margin exclusive of the effects of the excess burden. This rate of return falls to 20% when the costs of an excess burden of 20 cents on the dollar is assumed. Nous calculons le rendement estimatif des défenses consacrées à la recherche sur le mouton par le gouvernement du Canada entre 1968 et 1984 à ?aide ?une méthode fondée sur les surplus économiques. Nous comparons les mesures objectives (ex post) et subjectives (ex ante) des changements survenus au chapitre des excédents à la production. ?analyse de régression nous permet ?estimer la structure de retard des effets de la recherche sur la fonction de ?approvisionnement national, ce qui facilite ?évaluation du rendement moyen et du rendement à la marge. Nous examinons également les effets du fardeau excessif de ?impôt sur le rendement de la recherche sur le mouton. Le taux interne de rendement de la recherche portant sur le mouton a été évalué à environ 25% à la marge, en excluant les effets du fardeau excessif. Ce taux de rendement est abaissé à 20 % lorsqu'on tient compte ?un coût présumé du fardeau excessif de 20 cents par dollar.     

An Economic Analysis of the Returns to Canadian Swine Research: 1974–97

This paper reports a new set of estimates of the returns to swine research in Canada. These estimates are obtained using Agriculture and Agri‐Food Canada's Canadian Regional Agricultural Model (CRAM). Positive Mathematical Programming is incorporated into the model for use in this study. The CRAM allows the effects of supply shifts from technological change in the hog industry to interact with product and factor market conditions in the rest of Canadian agriculture. Extensive sensitivity analysis is conducted to examine the robustness of the return estimates under variations in some of the key assumptions employed in the analysis. The costs of public and private sector swine research are estimated. Public sector research costs are inclusive of the marginal excess burden of taxation. Overall, the estimated benefits from Canadian swine research are high relative to the estimated costs for the time period considered. Previous estimates of the returns to Canadian swine research were obtained by Huot et al. (1989) with a partial equilibrium model that did not allow for intra‐sectoral resource use adjustments. The estimated returns obtained in the present study are generally higher than those obtained by Huot et al. For example, the estimates obtained from the direct application of the econometrically estimated supply function in this study gave an internal rate of return of about 124% and a benefit‐cost ratio of 22.4 to 1. Huot et al reported comparable estimates of about 43% for the internal rate of return and 6–7 to 1 for the benefit‐cost ratio. The differences in returns are not solely attributable to the use of a multi‐market versus a single‐market partial equilibrium approach. There are also differences in the estimates of the marginal excess burden of taxation between the two studies. L'analyse que void présente une nouvelle série d'estimations quant au rendement de la recherche porcine au Canada. Ces estimations dérivent du Modèle d'analyse régionale de l'agriculture du Canada (MARAC) du ministère canadien de l'Agriculture et de l'Agroalimentaire. Aux fins de la présente étude, on avait intégré au modèle une programmation mathématique positive. Le MARAC autorise l'interaction entre les retombées d'une modification de l'offre attribuable au virage technologique de l'industrie porcine et les conditions du marché des produits et des facteurs dans le reste de l'agriculture canadienne. Les auteurs ont effectué une analyse de sensibilité poussée en vue d'établir la robustesse de leurs estimations quand variaient quelques‐unes des principales hypotheses de l'analyse. On a estimé le coût de la recherche sur les pores poursuivie par les secteurs public et privé. Dans le secteur public, le coût de la recherche incluait une charge fiscale légérement excessive. Dans l'ensemble, la recherche sur les porcs entreprise au Canada a rapporté beaucoup comparativement à ce qu'elle a coûté pendant la période à l'étude. Les estimations antérieures, établies par Huot et ses collaborateurs (1989), venaient d'un modèle àéquilibre partiel ne permettant aucun ajustement pour l'utilisation intra‐sectorielle des ressources. Les revenus estimés ici sont généralement plus élevés que ceux de Huot et de ses collaborateurs. Ainsi, une application directe de l'offre estimée par des méthodes économétriques à l'analyse donne un taux de rendement interne d'environ 124 % et un indice de rentabilité de 22,4 pour 1. À titre de comparaison, Huot et ses collaborateurs rapportent des résultats d'environ 43 % pour le taux de rendement interne et de 6 à 7 pour 1 en ce qui concerne l'indice de rentabilité. Pareil écart ne résulte pas uniquement du choix d'un modèle àéquilibre partiel reposant sur plusieurs marchés au lieu d'un seul; on relève aussi des variations dans l'estimation du léger excès de la charge fiscale entre les deux études.     

FIRM DYNAMICS IN AN URBAN ECONOMY *

We develop a new dynamic general equilibrium model to explain firm entry, exit, and relocation decisions in an urban economy with multiple locations and agglomeration externalities. We characterize the stationary distribution of firms that arises in equilibrium. We estimate the parameters of the model using a method of moments estimator. Using unique panel data collected by Dun and Bradstreet, we find that agglomeration externalities increase the productivity of firms by up to 8%. Economic policies that subsidize firm relocations to the central business district increase agglomeration externalities in that area. They also increase economic welfare in the economy.     

Culture in Neoinstitutional Economics: An Integration of Myrdal and Galbraith into the Veblen-Ayres Matrix

A bstract . Neoinstitutional economics , exemplified in this instance by the contributions of Gunnaar Myrdal and John K. Galbraith , exhibits a basic proclivity toward fragmentation. It is argued that a further advance of the Veblen-Ayres general theory of economic development will serve as the foundation to reverse such centrifugal tendencies and provide a basis for integration and synthesis. The key conceptual framework for analysis and theory resides in culture and its evolution. The core of culture is transformed through the processes of economic development fed by the dynamics of technological change. In a modified Veblen- Ayres matrix, social institutions are assumed to be integral to the organic whole of technology. Given further modifications of mainstream institutional economics contained in the "dichotomy of useful knowledge" and the "wheel of economic development," it is suggested that the cultural approaches of Myrdal and Galbraith might then be integrated into the culture-analysis of economic evolution inherent in mainstream institutional economics     

Canadian dairy policy and the returns to federal dairy cattle research

The economic surplus approach is used to estimate the returns to federal investments in dairy cattle research in Canada. A national supply function is estimated using time series data. Lagged research expenditures are included as explanatory variables in the model, facilitating the calculation of ***marginal as well as average benefits from research. Simulation analysis is used to study the effects of product market distortions associated with Canadian dairy policy as well as of the marginal excess burden on the rates of return to research and on the distribution of research benefits. Returns were found to be high at the margin. Distortions in the product market had a small effect on the overall returns to dairy cattle research but had a large impact on the distribution of research benefits. Rate of return estimates were found to be indicative of underinvestment even when the marginal excess burden was taken into account.     

PRODUCT MARKET DISTORTIONS AND THE RETURNS TO BROILER CHICKEN RESEARCH IN CANADA

The economic returns to Canadian federal broiler chicken research between 1968 and 1984 were estimated using the economic surplus approach. The impact of distortions in the product market and of the excess burden of taxes on the net benefits of research and the distribution of gross benefits between producers and consumers were assessed. Rates of return to research investments at the margin over this period were estimated to be between 52% and 60%. All of the benefits of this research have accrued to consumers, and producers have actually been made worse off by broiler research under the existing regime of supply management.
