THE COST OF THE U.S. SUGAR PROGRAM REVISITED 总被引:1,自引:0,他引:1

The article analyzes the welfare cost of the U.S. sugar program using a multimarket model of U.S. sweetener markets. The latter includes raw crops, sugar extraction and refining, and sweetener users (food-processing industries and final consumers). The authors address the industrial organization of food industries using sweeteners and treat the United States as a large importer. With the removal of the program, this article estimates (all figures in 1999 dollars) that in 1998 cane growers, sugar beet growers, and processors would have lost $307, $650, and $89 million, respectively; sweetener users would have gained $1.9 billion. World prices would have increased by 13.2%. The deadweight loss of the program is estimated at $532 million. 相似文献

Notwithstanding their common features, hedge funds remain an extremely diverse asset class. Information on fund styles is important for numerous purposes, such as portfolio construction, performance attribution and risk management. With fund self‐declaration being prone to (strategic) misclassification, return‐based taxonomies grouping funds along similarities in realized returns provide a useful alternative. We provide a consistent classification system of homogeneous groups of hedge funds based on self‐organizing maps. Whereas some fund categories such as managed futures are largely consistent in their self‐declared strategies, others, especially so‐called ‘equity hedge’ funds, display no or very limited return similarities. Furthermore, we also find evidence of fund managers performing undisclosed changes of their trading style over time. Those funds that misclassified themselves once are particularly likely to change their trading style again. Although style self‐declaration can, therefore, be quite misleading, our results indicate that hedge funds do not misdeclare their style strategically to improve their relative performance.

We develop a methodology for optimal design of financial instruments aimed to hedge some forms of risk that is not traded on financial markets. The idea is to minimize the risk of the issuer under the constraint imposed by a buyer who enters the transaction if and only if her risk level remains below a given threshold. Both agents have also the opportunity to invest all their residual wealth on financial markets, but with different access to financial investments. The problem is reduced to a unique inf-convolution problem involving a transformation of the initial risk measures.Received: December 2004, Mathematics Subject Classification (2000):

This paper considers a production-remanufacturing inventory model for a single product, where constant demand is satisfied from the inventory of newly produced and remanufactured items. Although the available models in the literature imply that collected used units (or returns) are disassembled for recovery purposes, these models really do not treat them as such. Contrary, the returns are assumed to be recovered as whole units, perhaps, for simplicity. This assumption may not capture the benefits reaped from product recovery programs. This paper addresses this limitation in the literature and assumes that each unit of a used product is collected and disassembled into components, where these components are sorted into subassemblies, which are fed back into the production-remanufacturing process. The returned subassemblies are remanufactured and reassembled to represent a second source of as-good-as-new units of the end-product. For this multi-component inventory problem, the question that needs to be answered is whether, or not, extreme strategies of either pure remanufacturing or pure production are more economical than a mixed strategy (one that combines both strategies). A mathematical model is developed that accounts for the inventories of subassemblies. The results suggested that not accounting for the disassembled components of a product leads to inappropriate inventory decisions that are not environmentally sound. 相似文献

This paper presents a macroeconomic approach to monitoring progress toward achieving the Millennium Development Goals (MDGs) in Sub‐Saharan Africa. At the heart of our framework is a macro model which captures key linkages between foreign aid, public investment (disaggregated into education, infrastructure and health), the supply side and poverty. The model is then linked through cross‐country regressions to indicators of malnutrition, infant mortality, life expectancy and access to safe water. A composite MDG Indicator is also calculated. The functioning of our framework is illustrated by simulating the impact of an increase in foreign aid to Niger at the MDG horizon of 2015, under alternative assumptions about the degree of efficiency of public investment. Our approach can serve as the building block for Strategy Papers for Human Development (SPAHD), a more encompassing concept than the current ‘Poverty Reduction’ Strategy Papers. 相似文献

A longitudinal investigation of group tracking of potential new applications and markets created by an emerging technology (cellular telephones) is used to gain more understanding of the shifts of cognitive frames of reference in the environmental tracking of emerging strategic issues. The dynamics of frame of reference shifts is examined through the derivation and operationalization of the concepts of templates, triggers and twitches. The results posit that examining the frame of reference shifts can be more informative than examining the frames themselves. Implications for strategic management practice and research are addressed. 相似文献

Abstract. This paper uses panel data to show that capital controls have a significant impact on international interest rate differentials. Various types of controls can be distinguished within the data. The analysis shows that the aforementioned effects of capital controls on interest rates are especially strong in the case of capital import controls on portfolio capital; the implementation of these controls has been suggested in the wake of the Asian Crisis to prevent further crises. The results presented herein contradict the hypothesis that capital controls can achieve a restructuring of the maturity of capital inflows without a distortion in international capital allocation. 相似文献
