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

This paper examines the negative market impact that resulted from the insurance regulators’ potential reclassification of 140 hybrid capital securities in spring and summer 2006. It illustrates how financial contagion can spring from a regulatory policy change that lacks transparency. We investigate the impact of the uncertainty surrounding the regulators’ true classification criteria by measuring the effect of the reclassification announcements on hybrid new issue volume, cumulative average abnormal returns, bid‐ask spreads, and yield spreads. The financial contagion adversely affected the entire hybrid capital securities market for six months. The effect was most pronounced among those hybrids that were eventually reclassified as common equity equivalents. It was greater for Yankee Tier 1 hybrids, which had been more popular with insurance firm investors prior to the reclassifications, than among non‐Tier 1 hybrids.  相似文献

A simple trading model is presented in which Bayes’ rule is used to aggregate traders’ forecasts about risky assets’ future returns. In this financial market, Bayes’ rule operates like an omnipotent market-maker performing functions that in 1776 Adam Smith attributed to an “invisible hand.” We have analyzed two distinct cases: in the first scenario, the traders’ forecast errors are uncorrelated, and in the second scenario, the traders’ forecast errors are correlated. The contribution of our paper is fourfold: first, we prove that the “efficient market” mean-return can be expressed as a complex linear combination of the traders’ forecasts. The weights depend on the forecast variances, as well as on the correlations among the traders’ forecasts. Second we show that the “efficient” variance is equal to the inverse of the sum of the traders’ precision errors, and is also related to the correlations among the traders’ forecast errors. Third, we prove that the efficient market return is the best linear minimum variance estimator (BLMVE) of the security’s mean return (in the sense that it minimizes the sum of the traders’ mean squared forecast errors). Thus, an efficient market aggregates traders’ heterogeneous information in an optimal way. Fourth, we prove that an efficient market produces a mean return (price) as a Blackwell sufficient (most informative) experiment among all possible aggregated expected return (price) forecasts.  相似文献

We report the results of a novel experiment that addresses two unresolved questions in the judgmental forecasting literature. First, how does combining the estimates of others differ from revising one’s own estimate based on the judgment of another? The experiment found that participants often ignored advice when revising an estimate but averaged estimates when combining. This was true despite receiving identical feedback about the accuracy of past judgments. Second, why do people consistently tend to overweight their own opinions at the expense of profitable advice? We compared two prominent explanations for this, differential access to reasons and egocentric beliefs, and found that neither adequately accounts for the overweighting of the self. Finally, echoing past research, we find that averaging opinions is often advantageous, but that choosing a single judge can perform well in certain predictable situations.  相似文献

In 1992 a blue‐ribbon group of US economists led by Michael Porter concluded that the US stock market‐based corporate model was misallocating resources and jeopardising US competitiveness. The faster growth of US economy since then and the supposed US lead in the spread of information technology has brought new legitimacy to the stock market and the corporate model, which is being hailed as the universal standard. Two main conclusions of the analysis presented here are: (a) there is no warrant for revising the blue‐ribbon group’s conclusion; and (b) even US corporations let alone developing country ones would be better off not having stock market valuation as a corporate goal.  相似文献

This paper studies the evolution of political institutions in the face of conflict. We examine institutional reform in a class of pivotal mechanisms—institutions that behave as if the resulting policy were determined by a “pivotal” decision maker drawn from the potential population of citizens and who holds full policy‐making authority at the time. A rule‐of‐succession describes the process by which pivotal decision makers in period t + 1 are, themselves, chosen by pivotal decision makers in period t. Two sources of conflict—class conflict, arising from differences in wealth, and ideological conflict, arising from differences in preferences—are examined. In each case, we characterize the unique Markov‐perfect equilibrium of the associated dynamic political game, and show that public decision‐making authority evolves monotonically downward in wealth and upward in ideological predisposition toward the public good. We then examine rules‐of‐succession when ideology and wealth exhibit correlation.  相似文献

Effective management of people is increasingly recognized in the literature as a vital contributor to organizational performance and indeed survival. Nevertheless, studies of the dynamics of human resource management in small entrepreneurial ventures are relatively sparse. In this paper we draw upon a range of behaviourally-informed research publications to demonstrate that a culture of owner-influenced individualism and informality pervades these ventures, affecting prime human resource issues such as performance related practices, training and development, work–life balance and other critical dimensions of employee welfare. A preference for informality and an absence of strategy to inform owner–employee relations sits uneasily alongside growing political pressures toward codification of the management of employees in small entrepreneurial ventures. The response to these pressures may have significant implications both for relationships with employees and for organizational performance.  相似文献
