The seller of N distinct objects is uncertain about the buyer's valuation for those objects. The seller's problem, to maximize expected revenue, consists of maximizing a linear functional over a convex set of mechanisms. A solution to the seller's problem can always be found in an extreme point of the feasible set. We identify the relevant extreme points and faces of the feasible set. We provide a simple algebraic procedure to determine whether a mechanism is an extreme point. We characterize the mechanisms that maximize revenue for some well-behaved distribution of buyer's valuations. 相似文献

This paper analyzes the effects of trade liberalization of tariff‐rate quotas under import “state trading enterprises” (STEs) in agriculture. An analytical framework is provided to determine the importance of which instrument is binding under competition (the in‐quota or out‐of‐quota tariff or the quota) and under the initial STE equilibrium. It also depends on whether or not the STE controls both the domestic market prices and owns/controls the import quota (and whether it is obligated to fill the quota or not). An empirical example of the rice STE in South Korea has simulations showing that an increase in imports can be achieved through a moderate expansion of the quota or a decrease in the out‐of‐quota tariff to the level where it becomes binding. However, a significant level of quota expansion induces the STE to switch to the autarky solution and social welfare declines. 相似文献

The methodology in this paper combines an input–output structural decomposition approach with the supply-side perspective of mainstream growth accounting. In explaining the intertemporal change in consumption per worker, three sets of effects are distinguished. First, contributions due to several types of technological changes are considered. Second, effects caused by changes in international trade are discerned. Third, composition effects that reflect structural shifts in demand (including changes in tastes) are quantified. As an empirical illustration, we analyze the developments in the U.K. between 1979 and 1990. 相似文献

We examine how offering digital content affects demand for print magazines. Using a searchable website archive, we measure the digital content offered by a sample of US consumer magazines from 1996 to 2001. We find strong evidence that digital content cannibalizes print sales. On average, a magazine’s print circulation declines about 3–4% when it offers a website. However, the effect varies with the type of digital content offered. Offering digital access to the entire contents of the current print magazine reduces print sales by about 9%. We find no evidence that digital content complements print magazines. These results are robust to including controls for unobserved magazine, category, and time effects, as well as controls for the impact of contemporaneous price changes and other factors. 相似文献

The U.S. Departments of Agriculture and Energyjointly analyzed the economic potential for,and impacts of, large-scale bioenergy
cropproduction in the United States. Anagricultural sector model (POLYSYS) wasmodified to include three potential bioenergycrops
(switchgrass, hybrid poplar, and willow). At farmgate prices of US $2.44/GJ, anestimated 17 million hectares of bioenergycrops,
annually yielding 171 million dry Mg ofbiomass, could potentially be produced at aprofit greater than existing agricultural
usesfor the land. The estimate assumes highproductivity management practices are permittedon Conservation Reserve Program
lands. Traditional crops prices are estimated toincrease 9 to 14 percent above baseline pricesand farm income increases annually
by US $6.0billion above baseline.At farmgate prices of US $1.83/GJ, anestimated 7.9 million hectares of bioenergycrops, annually

Fiscal sociology deals with the ramifications of the fiscal activities of the state into areas which are not their primary target. These effects may occur in sectors not directly affected such as related markets, but they may also occur outside the economic sphere proper, such as in politics, culture, religion, or society at large. Schumpeter contributed to the research project of fiscal sociology throughout his life. In this first approximation, his contribution is discussed in terms of his appreciation of three important scholars who all made landmark contributions to fiscal sociology: Franz Oppenheimer, Werner Sombart, and Gustav (von) Schmoller.JEL Classification:

ABSTRACTThe aim of this paper is to examine the relationship between external cooperation and entrepreneurial orientation (EO). This relationship is explored in cluster environment, wherein entrepreneurial organizations compete and cooperate simultaneously to pursue opportunities. The following hypothesis is tested: External cooperation is positively correlated with entrepreneurial orientation. The hypothesis is tested with a correlation analysis on a sample of 77 small-sized enterprises operating in the Malopolska region in Poland, wherein several clusters are active. Additionally, the regression analysis is conducted to examine the associations between inter-organizational cooperation and EO dimensions. The findings confirm that external cooperation is positively correlated with EO. This observation is confronted with a pro-competitive approach that is a constitutional element of the entrepreneurship concept. Moreover, the findings show that the correlation between external cooperation and a firm’s performance is stronger than between some other EO dimensions and performance. Additionally, the findings show the important role of relationships between organizations and their clients. In the paper, several remarks for development of the theory are discussed, including the need for incorporating inter-organizational cooperation into a set of entrepreneurial traits and reflecting it in entrepreneurial orientation scales. The findings confirm the importance of that direction of theory development that focuses on inter-organizational collaboration in the context of entrepreneurship. 相似文献

这次会议讨论的是一个很重要的题目──国企转型与企业文化构建。我们现在对企业文化的认识,如果同10年前相比,可以说是跨越了一个世纪。当时感觉企业文化是个新鲜东西,并不知道它有多大用途,好像很时髦,多数人对它的认识还是狭窄的、浮面的。10年后的今天,经过理论界的探索研究,特别是经过企业界的创新实践,使得我们对企业文化的认识有了很大的发展。中外企业文化杂志社利用庆祝创刊10周年的机会,组织大家共同研讨国企转型与企业文化构建,这个题目选得非常好。当前,企业文化在中国的需求,很重要的一点就是与国企转型联系在了一起。企业文化… 相似文献

A dual representation of a technology, e.g., a cost function, may not contain all of the technological information, but it will contain all of the information about input vectors that would be chosen by a cost-minimizing firm. At least this much is clear for deterministic technologies. The main question addressed in this paper is whether the same can be said about stochastic technologies and their dual representations. Despite some pessimism expressed in the stochastic frontier literature on this question, we argue that there is no extra cost imposed in the stochastic case. Thus, the conclusion of this paper is: Just dual it! 相似文献
