This paper concerns inverse DEA. The aim is to estimate input/output levels of a given Decision Making Unit (DMU) when some or all of its input/output levels are changed, under preserving the efficiency index. We show that in the case of estimating increased required input vector when the output vector is increased, the current method which uses weakly efficient solution of the relevant multiple objective optimization problem may fail. We propose some sufficient conditions for input estimation. 相似文献
The objective of this paper is to integrate the generalized gamma (GG) distribution into the information theoretic literature. We study information properties of the GG distribution and provide an assortment of information measures for the GG family, which includes the exponential, gamma, Weibull, and generalized normal distributions as its subfamilies. The measures include entropy representations of the log-likelihood ratio, AIC, and BIC, discriminating information between GG and its subfamilies, a minimum discriminating information function, power transformation information, and a maximum entropy index of fit to histogram. We provide the full parametric Bayesian inference for the discrimination information measures. We also provide Bayesian inference for the fit of GG model to histogram, using a semi-parametric Bayesian procedure, referred to as the maximum entropy Dirichlet (MED). The GG information measures are computed for duration of unemployment and duration of CEO tenure. 相似文献
The purpose of this work is to study the impact of trade openness on the economic growth of the countries bordering the Mediterranean using a panel of eight countries from 1975 to 2016. We apply ARDL panel which is a technique recently developed. We study the effects of openness to international trade on economic growth while incorporating economic policy variables. The results show that the variables of commercial and financial openness favor economic growth. The free trade agreements that the European Union has signed with certain countries in the Mediterranean basin are designed above all to encourage greater regional economic integration and an increase in their potential growth. Therefore, our findings show that the financial sector is slow to affect economic growth in these countries. This study reveals that human capital and the investment rate support the economic growth of our sample. In addition, we conclude that a process of economic convergence has begun in these countries. A causal analysis was carried out we found an unidirectional causality ranging from economic growth to trade openness.
This paper examines the interactions between fiscal and monetary policy for some former transition, emerging European economies over the 1995Q1–2010Q4 period by using a Markov regime-switching model. We consider the monetary policy rule proposed by Taylor (1993) and the fiscal policy rule suggested by Davig and Leeper (2007) in accounting for monetary and fiscal policy interactions. Empirical results suggest that monetary and fiscal policy rules exhibit switching properties between active and passive regimes and all countries followed both active and passive monetary policies. As for fiscal policy, the Czech Republic, Estonia, Hungary, and Slovenia seem to have alternated between active and passive fiscal regimes while fiscal policies of Poland and the Slovak Republic can be characterized by a single fiscal regime. Although the policy mix and the interactions between monetary and fiscal policy point a diverse picture in our sample countries, the monetary policy seems to be passive in all countries after 2000. This finding is consistent with the constraints imposed by European Union enlargement on monetary policy. 相似文献
We show that a seasonal good could be priced countercyclically due to the heterogeneous seasonal shifts in consumer valuations. We provide empirical support for our explanation based on two product categories (canned soup and tuna) studied in the literature. 相似文献
This empirical analysis of hotel properties in south-western Turkey draws on the market orientation, strategy, and capabilities literature to highlight the benefits of a differentiation strategy and customer-value focus for competitors in this industry. Relationship management and organizational resource management are key drivers of sales growth in this industry, and hotel operators facing high competitive intensity are particularly encouraged to develop these capabilities and to adopt a differentiation strategy instead of resorting to price cutting and other pricing and promotional tactics to grow revenues. Notable opportunities for future research include examining relationships between market orientation, customer satisfaction, and employee satisfaction in the Turkish hotel industry. 相似文献
Agricultural production efficiency in four irrigated cropping regions of the Punjab province of Pakistan was compared on the basis of a probabilistic frontier production function estimated from whole-farm survey data for the year 1984-85. It is found that the gross income of farmers can be increased by 13% at the current levels of resource use if the production gap between ‘best practice’ and ‘average’ farmers is suitably narrowed in all cropping regions. This will increase profits by up to 40%. No significant difference in technical efficiency was found across the regions. Economic efficiency was similar across all cropping regions except in the cotton region, which had significantly lower economic efficiency due to higher allocative inefficiency, which in turn was attributable to the more dynamic production technologies being adopted in that region. 相似文献
This paper develops an agent-based model of a stylized low income region in order to study the impact of natural disasters on population displacement, income, prices, and consumption with a focus on distributions and coping strategies of low income groups. Key features of the model include the integration of decentralized markets into a full economy in a spatially explicit way and the analysis of short-run adjustment processes. The model is calibrated to a low income region of rural agrarian Pakistan that faced severe floods in 2010. Dynamic adaptation by agents in response to falling income includes migrating and running down savings. Despite these consumption smoothing strategies, some low income groups are vulnerable to starvation. The paper showcases two hypothetical policy scenarios, a cash and a food transfer program, and tracks their effects on the welfare of low income groups in the economy. 相似文献
