This paper employs the economics of shortage framework to examine post-Mao reforms in Chinese state-owned industry. Performance has been disappointing because reforms through 1985 failed to fundamentally alter economic agent behavior. The “soft” budget constraints at the enterprise and local government levels continue to generate “quantity” and “expansion” drives. The resultant inflationary pressures have necessitated administrative interventions and thwarted reform progress. The Maoist legacy of active participation by local governments in economic management is high-lighted as a major obstacle to the elimination of paternalism in state-enterprise relations. 相似文献

In this paper, examination of the possibility of a ‘double marginalization’ problem existing in the Korean telecommunication industry is conducted and suggestions are made for the provision of a new scheme to eliminate this possibility by changing the pricing system for fixed-to-mobile calls. Based on five key economic characteristics in the Korean mobile market, a simple model for double marginalization in the telecommunication market is introduced. Evidence was found to suggest that a double marginalization problem is likely to exist within Korea's telecommunication industry as it is presently structured, and that this problem is further likely to have an adverse effect on the industry by inflating the price of fixed-to-mobile calls. Two alternatives are proposed to effectively remedy this double marginalization issue. It is also shown that prices of fixed-to-mobile calls could be lowered by changing the caller pays principle into a receiver pays principle. 相似文献

Real Investment Implications of Employee Stock Option Exercises 总被引:6,自引:0,他引:6
This paper examines a real cost of awarding employee stock options. Based on the observation that managers are extremely concerned about earnings-per-share dilution in equity related compensation, we predict and find that firms experiencing significant employee stock option (ESO) exercises shift resources away from real investments towards the repurchase of their own stocks. We further find weak evidence of a decline in subsequent firm performance (as measured by return on assets) for several years following the cut in discretionary investments as a result of stock option exercises, though this result is sensitive to the metric used to measure performance. Collectively, our findings indicate that ESO exercises potentially impose a real cost on the firm in terms of foregone investment opportunities. 相似文献

The efficiency of decomposition vs direct solution with implications for the question of decentralized or centralized planning 总被引:1,自引:0,他引:1
K. P. Wong 《Economics of Planning》1973,13(3):199-209
Conclusion The investigation provides overwhelming evidence that decomposition tends to become increasingly more efficient than direct solution as the number of subproblems becomes greater.Further investigation would be required to obtain a comparable picture of the behaviour of decomposition with respect to an increasing number of variables in the master problem as their range of variation in the present study is rather restricted.It is gratefully acknowledged: that in implementing the decompositional procedure on the computer I have benefitted from Mr. A. C. McKay's advice on matters relating to the computer programmes; also that I enjoyed the pleasant and friendly co-operation of the staff of the computer Centre, University of Birmingham, without which the difficulties involved in carrying out the present task would have been compounded manifold; that Dr. C.-L. Sandblom carefully studied this paper and suggested a number of valuable improvements. Finally, I should like to thank Professor Kronsjö for the encouragement that he has given to me in executing this project and to the research council which made this investigation possible. 相似文献

Summary A procedure is proposed in this paper for testing the shape parameter, of the Weibull distribution. The test statistic which is based on the extremal quotient, possesses a monotone property which makes it possible for rejection earlier than the last planned observation of the null hypothesis,H
0: =0 when the alternative hypothesis isH
a: <0 and early acceptance ofH
0 whenH
a: >0. The test being scale-free, does not require the scale parameter to be known. 相似文献

This paper tests the permanent income hypothesis (PIH) for public consumption. Unlike private agents, a government is a representative national, infinitely-lived agent that usually faces no liquidity constraints. Thus, the expectation is that the PIH restrictions should not be rejected for public consumption. However, using U.S. data, the paper is unable to find evidence supporting the permanent income model of public consumption. Public consumption is found to be sensitive to lagged public income and too smooth relative to permanent public income. The results therefore cast doubt on the characterization of the public sector as a social welfare optimizing agent. 相似文献

This study examines motivation and stock market reactions of firms announcing earnings in the Wall Street Journal (WSJ) after
filing with the Security Exchange Commission (SEC). Most firms announce earnings in the WSJ before SEC filing. Firms that
reverse this sequence are voluntarily delaying public earnings announcements. The authors find that these firms are not only
poor financial performers but also engage in earnings managements. They are delaying their WSJ announcements to postpone announcing
bad news. The authors find significant stock price reactions to both the SEC filing and the WSJ announcement. The price reaction
to earnings is incomplete at the SEC filings. The market continues reacting to firms' subsequent WSJ announcements as if the
SEC filing fails to communicate earnings information to some investors. 相似文献

Summary. We prove that, for finitely many demand observations, the Strong Axiom of Revealed Preference tests not only the existence of a strictly concave, strictly monotone and continuous utility generator, but also one that generates an infinitely differentiable demand function. Our results extend those of previous related results (Matzkin and Richter, 1991; Chiappori and Rochet, 1987), yielding differentiable demand functions but without requiring differentiable utility functions.Received: 1 November 2001, Revised: 5 February 2004, JEL Classification Numbers:

This paper analyzes a model of two-way movement of physical capital, and examines the effects of direct investment liberalization on resource allocation, income distribution and commodity trade. If either country or both countries liberalizes investment under exogenously given commodity prices, some factor owners in a country will gain but some others will lose. If capital movement affects commodity prices, all factor owners in a country may be better off after multilateral investment liberalization. In these cases, it will be much easier for the home country to sign an agreement liberalizing investment flows. 相似文献
