We provide the simple example of a refinancing game with incomplete information, where the lack of transparency is both necessary and sufficient for the propagation of local financial distress across disjoint financial networks. JEL Classification Number: F4.

At some stage in every household's family life cycle, the household is likely to make certain decisions with regard to its housing environment. Although the household's housing decisions essentially comprise the decision to move, and the selection of a new residence, the process from which these decisions are derived is very complex because varying circumstances could produce a multitude of different housing decisions. Due to the sheer complexity of the household's housing decision–making process, researchers have generally focused on individual decision–making stages rather than on the process as a whole. This paper therefore attempts to conceptualize the entire household housing decision–making process using theoretical concepts from the economic perspective, and then tests the conceptual model with empirical evidence drawn from the moving population within the multi–racial society in Singapore. 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 DETERMINANTS OF AUDIT FEES: SOME EMPIRICAL MODELS 总被引:2,自引:0,他引:2
This paper proposes a model of audit fee determination based upon size and other characteristics of the auditee and the auditor, and upon whether there has been a recent change of auditor (which might lead to a low-balling effect). A novel feature of the model is that auditee size is measured in two dimensions, sales and assets, and is allowed to have a quadratic relationship with audit fee. The model was estimated for a sample of large listed UK companies for the years 1981 to 1988. The results support the low-balling hypothesis and also provide insights into the distinctive role of the Big 8 firms in the audit market. 相似文献

Previous research on the intertemporal approach is based on the standard, real model of the balance of trade. This paper outlines a more general model that allows for monetary non-neutrality, and tests the general model against a restricted version that embodies neutrality. While the empirical analysis focuses on the UK trade balance during the Bretton Woods era, the fundamental issues are of interest to more than just students of Bretton Woods. 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

广东省经济开放度对经济增长的长期均衡效应研究 总被引:2,自引:0,他引:2
引进外资与对外贸易是广东省外向型经济发展的主要形式.运用协整分析技术和Granger因果关系检验,分析广东省经济开放度对经济增长的长期均衡效应,结果表明经济开放度各项指标与经济增长均存在正向的协整关系,增长是其外资依存度和实际关税率提高的原因,而外贸依存度的提高促进了增长;同时,广东省经济增长与粤港贸易依存度互为因果关系,相互之间存在较强的协整关系.因此,大力提高吸引外资的质量和水平,转变对外贸易增长方式,推进区域经济合作的全面发展,是广东省外向型经济实现持续稳定增长的主要途径. 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:
