Using a stochastic frontier methodology that incorporates Bayesian statistics, this paper analyzes the cost efficiency of real estate investment trusts (REITs) by observing the deviations of the measured costs of individual REITs from a defined efficient cost frontier. Using 1995–1997 data, we extend the previous research in this area and measure REIT efficiency more precisely by isolating random measurement error from the overall deviations from the efficient cost frontier. We calculate the magnitude of each REIT's managerial inefficiency, the industry inefficiency, and returns to scale. In addition, we assess specific characteristics of REITs for their contribution to inefficiency by calculating the odds ratio that a REIT with a specific characteristic is more efficient than a REIT with an alternative characteristic. The results show that, for the years studied, REITs are relatively cost efficient with most REITs facing increasing returns to scale. Additionally, the REIT's use of debt and the REIT's management style significantly affect the cost performance of REITs during the aforementioned time period. Finally, diversification across property types, as measured, does not seem to influence REIT cost efficiency. 相似文献

We analyze a signaling game where firms' financing announcements convey private information about their prospects but a moral hazard problem exists in that managers may suboptimally invest. Consequently, the attempt to address an asymmetric information problem exacerbates moral hazard. The equilibrium recognizes both imperfect information problems. Additionally, the firm must determine how to allocate funds between two technologies differing in cash flow timing and managerial accessibility. We define an above-average firm's comparative advantage as that technology which is most dominant relative to a firm with lesser prospects and show that the resultant equilibria follow the lines of the firm's comparative advantage. Finally, we show that separation may be achieved costlessly, i.e., with no explicit signaling cost. 相似文献

Agricultural Extension: Good Intentions and Hard Realities 总被引:3,自引:0,他引:3
What considerations lead policymakers to invest in agriculturalextension as a key public responsibility, and what factors andagency incentives explain differences in extension system performance?To help answer these questions, this article provides a frameworkoutlining farmers' demand for information, the public goodscharacter of extension services, and the organizational andpolitical attributes affecting the performance of extensionsystems. This conceptual framework is used to analyze severalextension modalities and their likely and actual effectiveness.The analysis highlights the efficiency gains that can come fromlocally decentralized delivery systems with incentive structuresbased on largely private provision, although in most poorercountries extension services will remain publicly funded. 相似文献

Tracing the income patterns of individual farm operators whose major source of income is generally derived from farming indicates that off-farm income is becoming an increasingly important income component. The relative importance of off-farm income has nearly quadrupled during the last 20 years, rising from about 10 percent of total income to about 37 percent of total income. Most of this off-farm income can be traced to wages and salaries. These fractions are heavily dependent upon relative income levels. In 1970, very low income farmers posted an aggregate net farm loss whereas the $15,000 - $20,000 class secured about three-quarters of their total income from farm sources. In this same year, wages and salaries were generally the prime off-farm income source for farmers with an assessed income of less than $20,000. Dividends and interest were more important to farmers with an income in excess of $20,000. These differences are faithfully reflected in the regional compilations. As a percent of total income, off-farm income ranged from 41 percent in Ontario to about 29 percent in Quebec. The composition of off-farm sources also varies considerably between regions. In 1970 the income position of taxable unincorporated farm operators (who relied on the farm for their major source of income) remained relatively unfavorable. These farmers still had one of the lowest average incomes of any major occupational class in Canada, with an income distribution which was relatively equally distributed between income classes and not unlike that of the national average. These assessed income statistics, of course, are not necessarily indicative of the welfare position of the respective occupational classes. The calculations conducted are simply illustrative of how income tax statistics can be utilized to facilitate our understanding of the income structure in primary agriculture today. The exercise simply underlines the observation that: The fact that there are conceptual differences between income tax data and other data sources should not detract from the usefulness of the income tax data …. Income tax statistics can stand as an independent data source for the analysis of a variety of issues [13]. For many purposes the tax definition of a farm operator may be more operational than the concept of a farmer as defined in the Census of Agriculture. We might profit considerably from further analyses which attempt to disaggregate Census farms into more homogeneous farm-types using the tax statistics available. 相似文献

This paper proposes two new weighting schemes that average forecasts based on different estimation windows in order to account for possible structural change. The first scheme weights the forecasts according to the values of reversed ordered CUSUM (ROC) test statistics, while the second weighting method simply assigns heavier weights to forecasts that use more recent information. Simulation results show that, when structural breaks are present, forecasts based on the first weighting scheme outperform those based on a procedure that simply uses ROC tests to choose and forecast from a single post-break estimation window. Combination forecasts based on our second weighting scheme outperform equally weighted combination forecasts. An empirical application based on a NAIRU Phillips curve model for the G7 countries illustrates these findings, and also shows that combination forecasts can outperform the random walk forecasting model. 相似文献

Since all macroeconomic policies are enacted within a certain set of distributive relations and institutional structures, the employment intensity of growth is likely to vary for men and women depending on the nature and context of output growth. I examine the gendered nature of this growth-employment nexus by analyzing the differential impacts that macroeconomic policies and structures have on growth’s employment intensity by gender for eighty countries in the period from 1990 to 2012. Such an understanding is of particular relevance to policymakers concerned with the linkages between growth and human development, as the question of whether the benefits of economic growth are broadly shared is one that centers on the capacity of economies to generate high-quality employment. Although education levels and non-agricultural sectors are associated with more employment intensive growth for men and women, policies supporting reductions in non-wage care work, prioritizing public expenditures on education, and promoting secondary school enrollment for girls are especially linked with growth that is more employment intensive for women. The results I obtain here illuminate broad trends through a very wide lens and should be applied in conjunction with more intimate knowledge of how cultural, technological, legal, political, and economic activities uniquely affect one another in particular countries. 相似文献

We compile an IO toolkit for aggregative games with positive and normative comparative statics results for asymmetric oligopoly in the short and long run. We characterize the class of aggregative Bertrand and Cournot oligopoly games, and the subset for which the aggregate is a summary statistic for consumer welfare. We close the model with a monopolistically competitive fringe for long-run analysis. Remarkably, we show strong neutrality properties in the long run across a wide range of market structures. The results elucidate aggregative games as a unifying principle in the literature on merger analysis, privatization, Stackelberg leadership, and cost shocks. 相似文献

We analyze the effect of the receipt of remittances on the education and health of children in Kyrgyzstan during a volatile period of their recent history, 2005–2009. The country experienced revolution in 2005 and the global financial crisis beginning in 2008. Both events impact human capital investment, and the changes vary by region of the country. We use fixed effects estimation and fixed effects, instrumental variables estimation to isolate the effects of remittances and other events on human capital. We find that boys aged 14–18 in remittances’ receiving households are less likely to be enrolled in school than other children. We also find that girls in remittances’ receiving households are more likely to be malnourished (thin). Both effects are relatively small. Remittances do not improve the human capital of children left behind. However, we do find an overall positive improvement in school enrollment among young children between 2005 and 2009 but a negative trend in enrollment among older boys and girls. Nutrition improves over time. Regional differences are apparent in these trends in nutrition and education. 相似文献
