This paper examines the extent to which the concept of vertical coordination in the agro-food sector lends itself to specification or measurement in a manner that is analytically useful. Based on a combination of theory and empirical evidence, it is suggested that vertical organization can be specified as a parameter, variable in degree of control by principal over agent. Such a specification has potential application in analytical models concerned with what gives rise to vertical ties and/or their economic consequences. Drawing principally on the concepts of transactions costs, factor price distortion, and vertical restraint, analytical attention is directed to the economic incentives for, and performance implications of the use of linkages other than spot market transactions for coordinating vertically interdependent stages in the food chain. Research challenges are identified.  相似文献

The offering prices of 64 issues of a popular retail structured equity product were, on average, almost 8% greater than estimates of the products' fair market values obtained using option pricing methods. Under reasonable assumptions about the underlying stocks' expected returns, the mean expected return estimate on the structured products is slightly below zero. The products do not provide tax, liquidity, or other benefits, and it is difficult to rationalize their purchase by informed rational investors. Our findings are, however, consistent with the recent hypothesis that issuing firms might shroud some aspects of innovative securities or introduce complexity to exploit uninformed investors.  相似文献

Information technology and the Japanese economy   总被引:2,自引:0,他引:2  
In this paper we compare sources of economic growth in Japan and the United States from 1975 through 2003, focusing on the role of information technology (IT). We have adjusted Japanese data to conform to US definitions in order to provide a rigorous comparison between the two economies. The adjusted data show that the share of the Japanese gross domestic product devoted to investment in computers, telecommunications equipment, and software rose sharply after 1995. The contribution of total factor productivity growth from the IT sector in Japan also increased, while the contributions of labor input and productivity growth from the non-IT sector lagged far behind the United States. Our projection of potential economic growth in Japan from for the next decade is substantially below that in the United States, mainly due to slower growth of labor input. Our projections of labor productivity growth in the two economies are much more similar. J. Japanese Int. Economies 19 (4) (2005) 460–481.  相似文献

Current methods for assessing capacity and its utilisation infisheries operate at the firm-level, but neglect industry capacity.Here, we introduce the Johansen-Färe measure of plant capacityof the firm into a multi-output, frontier-based version of theshort-run Johansen industry model. The model determines firmcapacity utilisation such that current industry outputs aremaintained, while minimising the use of fixed inputs at industrylevel and assuming abundant variable inputs. Policy extensionsrelevant to combating overfishing include tightening quotas,seasonal closures, linking economic and plant capacity, decommissioningschemes and area closures, implementation issues and equityconsiderations. The application to the Danish fisheries revealssubstantial overcapacity in the Danish fleet.  相似文献

ABSTRACT This study first develops an empirically based Western charismatic leadership profile. Using confirmatory factor analysis, the profile is compared with a profile of Iranian managers. The results demonstrate that despite major cultural differences in the two countries, there are core similarities in the profiles across the two cultures. The Canadian charismatic profile of vision, tenacity, intellectual challenge, self-sacrifice, and eloquence is substantially confirmed within the Iranian sample. But we also show that Iranian managers' ratings are significantly lower than those of the Canadian managers, indicating potentially different behavioural manifestations. The paper speculates that while the differences are probably due to cultural differences, the similarities may be due to universal intrinsic human desire for morality, autonomy, and achievement.  相似文献

Market timers without timing skill suffer a penalty relative to buy-and-hold investors in the form of higher portfolio risk. With transactions costs, timers suffer lower expected returns as well. We derive the magnitude of this penalty for a timer randomly switching funds between two or more risky assets. Assuming costless trades, a U.S.-based timer randomly switching between U.S. and Japanese national stock funds can expect to face a 26.2% higher standard deviation than a comparable buy-and-hold investor at the same level of expected return. A timer randomly switching between a globally diversified equity portfolio and U.S. T-bills faces a 50.3% higher standard deviation of return than a comparable buy-and-hold investor.  相似文献

Using nonparametric, production‐frontier methods, we decompose labor productivity growth into components attributable to technological change (shifts in the world production frontier), technological catch‐up (movements toward or away from the frontier), and physical and human capital accumulation (movements along the frontier). We find that (1) technological change is decidedly nonneutral, (2) productivity growth is driven primarily by physical and human capital accumulation, (3) the increased international dispersion of productivity is explained primarily by physical capital accumulation, and (4) international polarization (the shift from a unimodal to a bimodal distribution) is brought about primarily by efficiency changes (technological catch‐up).  相似文献

This paper develops a classification system of temporal orientations in an effort to provide processual researchers with a framework for understanding the potential impact of temporal orientations on processual research methods and findings. In developing the classification system four general conceptions of time are reviewed, including physiological, objective, psychological, and socially constructed relative time. Specific dimensions of temporal orientation previously studied are identified, and additional dimensions are offered. It is suggested that temporal concerns are endemic to management and organizational processes, and that differences in temporal orientations among researchers and organizational informants should be considered when conducting processual research.  相似文献

Summary This paper examines the structure and predictions of six applied general equilibrium models used to evaluate the 1986 Tax Reform Act in the United States. The models agree that the effects on national income will be fairly small. They disagree on the size of the improvement in economic efficiency from more neutral taxation of different capital assets, and on the size of the intertemporal inefficiency when capital formation is discouraged through a higher rate of taxation. This new application of general equilibrium models to an actual reform highlights the need to test predictions against empirical evidence.The views expressed are solely those of the author and do not necessarily reflect those of the Federal Reserve Bank of Boston or the Federal Reserve System. The author is grateful to J. von Sinderen, Laus Bovenberg, Lawrence Goulder, and other participants at the conference for their helpful comments, and to the authors of the studies reviewed in this paper for instructive discussions.Prepared for The Netherlands Central Planning Bureau Symposium on Applied General Equilibrium Models, Noordwijk, December 4–5, 1989.  相似文献
