This paper examines the influence of unemployment insurance (UI) on the length of nonemployment spells experienced by young workers. The analysis introduces a flexible duration model to estimate the effects of the weekly benefit amount and weeks of eligibility on the amount of time spent between jobs by men, distinguishing between the experiences of UI and non-UI recipients. The empirical findings suggest three conclusions: (1) UI recipients experience longer spells of nonemployment than their non-UI recipient counterparts, at least up to the point of exhaustion of UI benefits; (2) the level of the weekly benefit amount does not significantly affect the length of nonemployment spells; and (3) increasing the number of weeks of eligibility offered by a UI program leads to longer episodes of nonemployment.  相似文献

This paper contributes to the productivity literature in developing country agriculture by quantifying the level of efficiency for a sample of peasant farmers from Eastern Paraguay. A stochastic efficiency decomposition methodology is used to derive technical, allocative and economic efficiency measures separately for cotton and cassava. An average economic efficiency of 40.1% for cotton and of 52.3% for cassava is found, which suggests considerable room for productivity gains for the farms in the sample through better use of available resources given the state of technology. Gains in output through productivity growth have become increasingly important to Paraguay as the opportunities to bring additional virgin lands into cultivation have significantly diminished in recent years. No clear strategy to improve farm productivity could be gleaned from an examination of the relationship between efficiency and various socioeconomic variables. One possible explanation for this finding is the existence of a stage of development threshold below which there is no consistent relationship between socioeconomic variables and productivity. If this is the case, then our results suggest that this sample of Paraguayan peasants are yet to reach such a threshold. Hence, improvements in educational and extension services, for example, would be needed to go beyond this threshold. Once this is accomplished, additional productivity gains would be obtained by further investments in human capital and related factors.  相似文献

Three policy-relevant questions about multifamily mortgage originations (MFOs) are addressed. First, what is the annual volume of MFOs? This analysis highlights differences and problems among three publicly available multifamily lending surveys; the 1993 volume is estimated at $30 billion. Second, what is the size distribution of multifamily mortgages? Using kernel density estimation, variation in this distribution among central cities and suburbs, underserved areas, and lender type is examined. Third, what are the primary determinants of the variation in multifamily lending? A relatively simple regression model is estimated to shed light on the variables most highly correlated with multifamily lending. Tract income relative to MSA median income and minority concentrations are shown to be highly correlated with lending volume, but the largest source of variation is the number of multifamily rental units in the tract.  相似文献

Business ethics has gained much attention over the past decade in both work and educational settings. This study used a version of Lysonski and Gaidis' (1991) ethical vignettes to examine by gender the ethical views of 165 Canadian undergraduate management students, to examine the psychometric properties and construct validity of the instrument, and to determine if the instrument is a useful tool for introducing undergraduates to the topic of ethics in management practice. Results showed that while the instrument is a useful teaching tool, it has psychometric and validity inadequacies that need to be corrected.Robert Loo is currently a Professor of Human Resource Management and Organizational Studies in the Faculty of Management at the University of Lethbridge, Canada. Over the past 20 years, he has published extensively in the management and psychology literature. Ethics is a key theme throughout every management course he teaches. Bob strives to make ethics a relevant and interesting issue for students by using a variety of learning techniques such as cases, videos, self-assessment tools, and research projects.  相似文献

This article investigates the relationship between a debtor country's external financial indicators and the costs associated with the insurance of export credits to that country. For this purpose a stylized model of export credit insurance (ECI) is developed, the central idea being that ECI is similar to a contingent claim such as a European put option. Thus, tools from option pricing theory were used to calculate the price of ECI, implying that not only the current financial position but also the volatility of the changes in that position determine such costs. The empirical results of a statistical analysis of the premium rates for ECI, applied by a private export credit insurer to seventy-seven developing countries during 1993, provide some support for these hypotheses. In particular, the reserves-over-imports ratio of a debtor country and the volatility of the rates of change of this ratio appear to contribute significantly to the premium rates that apply to that country. Thus, the article provides evidence that option pricing parameters do play role in practical insurance pricing, even if this pricing is not explicitly based on these parameters. Premium rates are set as if an underlying option market operated. Thus, the trade of countries with volatile external financial positions is saddled with higher costs than that of countries with more stable positions.  相似文献

The number of intermediary levels between a manufacturer and the final market in a distribution channel varies from industry to industry. In some cases, none are used (i.e. the distribution function is vertically integrated), while several middleman levels are used in other cases (e.g. the use of a wholesaler, a jobber, and a retailer in the distribution of meat). In this paper we examine the effect of competition on the profit-maximizing length of the distribution channel. We find that the optimal number of middleman levels increases with the substitutability of products in the market, but that there are institutional limits on the maximum number of levels in a channel. The analysis also suggests that differences in the objectives of channel members (e.g. the maximization of total channel profit versus the maximization of each member's individual profit) affect optimal channel length: a goal of total channel profit maximization produces a channel at least as long as one of individual (non-co-operative) member profit maximization. The work thus complements existing research focusing on intra-channel (e.g. cost-based) explanations of channel length, using a framework similar to those investigating competitive incentives for vertical integration in distribution.  相似文献

This article analyses the effects of action aimed at narrowing the gap between South Africa's ‘two agricultures’, specifically the effects of the Farmer Support Programme (FSP) on structural aspects of maize production under different marketing policies. This is done by assembling a sectoral linear programming model of the South African summer-rainfall grain-producing area. The emphasis is on the inclusion of supply, demand and production risk. Results show that the effects of a successful FSP on specific interest groups, e.g. consumers of a specific product, or producers in a specific region, depend on the marketing policy followed, as well as on the effectiveness of the FSP. The analysis accentuates the interrelationships in South African crop production and illustrates how past policies ignored regional comparative advantages, distorted regional development and affected social welfare.  相似文献

This paper presents the basic analytics of a debt/equity swap and illustrates the concept with a detailed example of American Express Bank's swap transactions that began in 1986 and have resulted in construction of seven hotels in Mexico during the course of the swap agreement. The economics of the swap are presented from the lending bank's view, from the foreign direct investor's view, and from the borrowing country's view. It is concluded that: swaps offer net benefits to the borrower country when additional investment is generated (from the swap transaction itself and/or from encouraging further investment as a result of the swap policy); they offer net benefits to the lender when future loan servicing prospects are poor and viable investment opportunities exist; and they offer net benefits to the direct investor when the cost of financing the investment through the swap is less than for alternative financing sources.
The analytical framework presented here allows the bank lender to formally compare alternatives of holding impaired LDC loans on its books, selling the loans in the secondary market, trading the loans for loans from another country, and swapping the loans for equity investments in the borrowing country. It similarly allows the government policymaker to compare the relevant economic costs and benefits of swaps, so that better swap policies can be developed.  相似文献
