Structural changes in Saskatchewan agriculture have led to significant changes in the time allocation of labor of farm women. This paper analyzes the nonfarm labor market participation and labor supply of farm women in the theoretical context of a household production function and contrasts them with those of men. Participation is analyzed using probit models, and nonfarm labor supply functions are estimated using tobit models. Personal characteristics such as age, education, number of children and nonfarm labor participation of the spouse are significantly related to the nonfarm labor market participation and labor supply of farm women, and the direction of influence is as expected. Farm characteristics such as farm size and type are significant in the case of males but not for females. Labor market characteristics are represented only by distance to the nearest center of Complete Shopping Center status or higher and, while this variable is negatively significant for males as expected, it is not significant for females Les changements structurels qui on frappé l'agriculture de la Saskatchewan ont entraîné des modifications significatives à la répartition du temps des agricultrices en matière de travail. L'article présente une analyse de la participation au marché du travail non agricole, ainsi que de l'offre de main-d'oeuvre des agricultrices, dans le contexte théorique d'une fonction de production de ménage, en comparaison avec la situation observée chez les hommes. Le degré de participation e'tait analysé à partir de modèles probit et les fonctions d'offre de main-d'oeuvre non agricole étaient estimées à partir de modéles tobit. Les caractères personnels comme l'âge, I'instruction, le nombre d'enfants et la participation du conjoint à un travail non agricole étaient significativement reliés, dans le sens attendu, à la participation des femmes au marché du travail non agricole et au temps qu'elles pouvaient y consacrer. Les caractères de l'exploitation, superficie et type, n'étaient significatifs que pour les hommes mais pas pour les femmes. Le seul caractére du marché de main-d'oeuvre considéré était la distance entre la ferme et l'agglomération la plus proche de niveau de centre commercial complet ou de niveau supérieur. Bien que, comme on pouvait s'y attendre, cette variable était significativement négative dans le cas des hommes, elle n'avait pas de valeur significative pour les femmes  相似文献

Most studies of the impacts of global warming policy have been performed at the national level. However, national averages obscure the fact that some regions may be affected much more than others. We formulated a regional computable general equilibrium model to analyze the impact of a carbon tax on the Pennsylvania economy. The model incorporates special features relating to labor mobility, trade and energy substitution for this purpose. Our results indicate significant negative overall impacts on the Pennsylvania economy, primarily because it is a major producer and user of fossil fuels, especially coal, and because it is highly industrialized. Sensitivity analyses on key parameters and model assumptions indicate that our results are robust.  相似文献

Over the past decade, input–output structural decomposition analysis (SDA) has developed into a major analytical tool. We review the development of SDA and its relationship to other methodologies. We present the fundamental principles of alternative approaches to deriving SDA estimating equations and explore the various decompositions of changes in IO tables. We also identify several complications and unresolved issues. Most importantly, we find that a rigorous grounding in economic theory is lacking for SDA, but we are able to offer some suggestions as to how it might be established.  相似文献

Which International Institutions Promote International Trade?   总被引:1,自引:0,他引:1  
This paper estimates the effect on international trade of three multilateral organizations intended to increase trade: (1) the World Trade Organization (WTO) and its predecessor the General Agreement on Tariffs and Trade (GATT); (2) the International Monetary Fund (IMF); and (3) the Organisation for Economic Co‐operation and Development (OECD) and its predecessor the Organisation for European Economic Co‐operation (OEEC). I use a standard “gravity” model of bilateral merchandise trade and a large panel dataset covering over 50 years and 175 countries. My results indicate that OECD membership has had a consistently large positive effect on trade, while accession to the GATT/WTO also increases trade.  相似文献

In many regions of the globe today outside the US and Canada, existing networks for evaluating borrowers' credit histories, for recording borrowers' pledges of assets backing loans, and for the legal enforcement of creditor claims are often poorly developed. Inside North America these problems with credit information flows and legal enforcement systems are most evident inside Mexico, where credit reporting networks and the courts work under a somewhat different set of rules than in Canada and the United States. A national mail survey of more than 300 US banks lending across international boundaries into Mexico found that many US bankers have reservations about the credibility of credit reporting and credit security systems inside Mexico. If these reservations persist, they can lead to a fundamental restructuring of that developing nation's industry that could discourage international capital inflows and curtail the emergence of small business. Indeed, unless current credit information flows are more fully integrated and are of more uniform quality throughout North America, the North American Free Trade Agreement (NAFTA) is likely to continue to fall short of its promise of significant job growth and improved living standards throughout the continent. © 1997 John Wiley & Sons, Inc.  相似文献

This study uses statistical cost accounting techniques to examine the relationship between bank profitability and two dimensions of operating performance — pricing and operating efficiency. The traditional statistical cost accounting model, which relates a firm's income to its asset and liability mix, is expanded to account for differences in market structure, regional demand and supply conditions, and macroeconomics factors. The study focuses on large (above $500 million in domestic deposits) banks, comparing a sample of relatively profitable banks against a matched group of much less profitable banks over the period 1970–1977. After allowing for regional supply and demand factors, the high and low-profit banks are estimated to earn equal market rates of return on individual assets and liabilities. There is virtually no evidence that differential prices are an important discriminator between the two bank groups. Some evidence is found that the high-earnings banks experience lower operating costs on some liabilities, but the opposite is true with respect to selected asset items. After taxes are taken into account, however, any such cost differentials virtually disappear. Overall, there is no compelling evidence that high-profit banks are characterized by greater operating efficiency than their low-earnings counterparts. This finding is consistent with the view that over time, and especially among relatively large banks, information flows and competitive pressures act to reduce operating efficiency differences that may appear in the short run.  相似文献

Financial intermediation in Britain can be said to have reached maturity before the war, since when the growth of banks has been critically a question of market share. Until the shift in monetary policy away from direct restriction of bank lending that began about nine years ago, credit restriction added to other factors, like taxation and the bank cartel, limiting the ability of the banks to compete. The author argues that an open-market policy directed toward money supply control need not discriminate against banks. However, the re-introduction of bank lending restrictions through the use of Special Deposits and, even more so, through the use of Supplementary Special Deposits has worked to favour non-bank deposit intermediaries. The distortions caused by the Supplementary Special Deposits not only discriminate against the banks; they are also likely to undermine the use of monetary policy itself. What are required are government policies, especially with regard to the size of the public sector borrowing requi rement, that make possible the goal of a non-discriminatory open-market policy, without the need for direct controls on lending by financial institutions.  相似文献
