This paper presents a simple two-good general equilibrium model of exchange in which demands are linear functions of relative prices. The solution of the model is represented by a cubic equation which can have either a single root which corresponds to a unique equilibrium price or three roots corresponding to multiple equilibria. The major properties of the model are that the relative price can make large discrete jumps in response to small parameter changes, and can display hysteresis. The paper shows how recent developments in non-linear methods can be used to examine the equilibrium properties of the model and establish conditions under which multiple equilibria can arise. The model is compared with that used by Shapley and Shubik. 相似文献

Simple organizations, composed of operatives and one manager, may be organized as a hierarchy with the manager appropriating all profits or as a partnership with (say) equal shares of profits. Conditions on profitability and the optimal span of control are analyzed. Next, partnerships are considered and alternative incentives and distributions are compared. When partners are free to choose their time inputs, then a sufficiently high preference for leisure as against income will make a partnership more attractive even though it is less profitable. 相似文献

Abstract ** : The purpose of this paper is to perform a cross‐country survey of the level of integration of systems of financial cooperatives (FC) and its effect on measures of performance. We develop a classification scheme based on a theoretical framework that builds on published work using transaction cost economics (TCE) to explain integration of large numbers of financial cooperatives into networks. We identify three critical levels of increasing integration we call respectively atomized systems, consensual networks and strategic networks. Further, we test some of the propositions that result from the theoretical framework on an international sample of financial cooperative systems. Based on this analysis we can conclude that: (i) Integration is less (more) important in developing (more developed) countries and for very small (large) financial cooperatives as a determinant of efficiency. However, integration tends to reduce volatility of efficiency and performance regardless of development. (ii) Integration appears to help control measure of managers' expense preferences that tend to affect performance of FC. (iii) Despite high costs of running hub‐like organizations in highly integrated system, these systems economize in bounded rationality and operate at lower costs than less integrated systems. 相似文献

Summary. A model that includes the cost of producing money is presented and the nature of the inefficient equilibria in the model
are examined. It is suggested that if one acknowledges that transactions are a form of production, which requires the consumption
of resources, then the concept of Pareto optimality is inappropriate for assessing efficiency. Instead it becomes necessary
to provide an appropriate comparative analysis of alternative transactions mechanisms in the appropriate context.

This paper assesses the empirical plausibility of the view that aggregate productivity stocks account for most of the variability in post-World War II US output. We argue that the type of evidence forwarded by proponents of this proposition is too fragile to be believable. The answer could be 70% as Kydland and Prescott (1989) claim, but the data contain almost no evidence against either the view that the answer is really 5% or that the answer is really 200%. Moreover point estimates of the importance of technology shocks are extremely sensitive to small perturbations in the theory. Depending on the sample period investigated, allowing for labor-hoarding behavior in an otherwise standard RBC model reduces the ability of technology shocks to account for aggregate fluctuations by between 30% to 60%. 相似文献

Family income and child outcomes in Canada 总被引:1,自引:0,他引:1
Abstract. A positive relationship between income and child outcomes has been observed in data from numerous countries. A key question concerns the extent to which this association represents a causal relationship as opposed to unobserved heterogeneity. We use data from the National Longitudinal Survey of Children and Youth to implement a series of empirical strategies for estimating the existence and size of the effect of income on three measures of cognition. Our results indicate that the effect of income on these outcomes may well be positive, but that it is likely to be smaller than conventional estimates. JEL Classification: I10 相似文献

In trying to explain the often painful process of corporate restructuring, fingers are frequently pointed at inefficient management. This gives short shrift, however, to an important result of breaking up large, integrated corporations and selling them in smaller pieces: it makes the capital market more nearly complete, and there are strong theoretical arguments that this enhances value. We report the results of a natural experiment that occurred in the oil and gas industry, in which eleven integrated corporations formed publicly traded partnerships to hold their domestic production properties, yet (with few exceptions) retained most of the partnership units under corporate ownership. This behavior avoids any significant change in corporate governance, and is inconsistent with the tax motive popularly attributed as the reason for forming these partnerships; yet we find that significant positive abnormal returns accrued to stockholders when the formations were announced. The results we observe, therefore, support the theory that additional value can be realized by expanding the set of opportunities available to the investment community. 相似文献

We examine whether the sorting of high- and low-achieving students into classes of different sizes results in a regressive or compensatory pattern of class sizes for 18 national school systems. Sorting effects are identified by subtracting the causal effect of class size on performance from their total correlation. Our empirical results reveal strongly compensatory patterns of sorting within and especially between schools in many countries. Only the United States, which has a decentralized education finance and considerable residential mobility, exhibits regressive between-school sorting. Between-school sorting is more compensatory in systems with ability tracking. Within-school sorting is more compensatory where administrators rather than teachers assign students to classrooms. 相似文献

We analyse the state of the art in the field of life cycle portfolio choice, a recent strand of the literature on intertemporal
portfolio selection. Life cycle models are designed to identify optimal savings and portfolio policies over the lifetime of
investors. They can help to improve pension schemes by showing how these could be specifically tailored to the individual
employee’s circumstances to overcome the ‘one-size-fits-all’ philosophy still prevailing in parts of the mandatory retirement
savings system. To facilitate comparison, we first describe set-up, solution method and characteristic results for a basic
model and then derive a general framework to classify existing contributions. We highlight the models’ strengths and weaknesses
and assess their ability to resolve existing portfolio puzzles. Lessons from the literature are summarized and promising areas
for further research identified.
