The hazard rate of investment is derived within a real‐option model, and its properties are analysed so as to directly study the relation between uncertainty and investment. Maximum likelihood estimates of the hazard are calculated using a sample of multinational enterprises (MNEs) that invested in Central and Eastern Europe over the period 1990–98. Employing a standard, non‐parametric specification of the hazard, our measure of uncertainty has a negative effect on investment, but the reduced‐form model is unable to control for nonlinearities in the relationship. The structural estimation of the option‐based hazard is instead able to account for the nonlinearities and exhibits a significant value of waiting, although the latter is independent of our measure of uncertainty. This finding supports the existence of alternative channels through which uncertainty can affect investment. 相似文献

4P、4C与4R:交易费用经济学的视角 总被引:1,自引:0,他引:1
宋思根 《上海市经济管理干部学院学报》2004,2(4):18-23
4P是经典营销理论的核心内容之一。随着经济、文化和技术的全球化与区域化不断发展,市场竞争异常激烈,顾客在大部分领域取得了绝对的选择权,营销理论随之出现了4C和4R等“崭新”内容。从交易费用经济学的角度看,4C和4R不是对4P的替代,而是一种重要补充和发展。 相似文献

Validating the international tourist role scale 总被引:1,自引:0,他引:1
This study was designed to validate the international tourist role scale and the three dimensions it revealed. The purpose of this attitudinal scale was to measure the tourist role typology. United States adult outbound tourists flying with 11 major airlines returned useful questionnaires. This study validated the role scale as a reliable one that properly identified three conceptual dimensions of international tourist typology and successfully provided measures of tourists’ novelty-seeking preferences on the three dimensions. The study demonstrated, however, that the scale would measure the novelty-seeking preferences of international tourists more effectively if it were supplemented by other measures. 相似文献

食品安全关系到每一个人的健康与生存,但以乳品为代表的食品类企业却往往忽视质量控制而热衷于销量扩张.本文从技术约束和信息不对称的角度对此给出了一种解释.分析表明:竞争压力未必是解释该现象的关键因素;只要产品的市场容量较大、并且在投资不足的前提下提供优质产品的产能相对较小,即使没有竞争的压力,厂商在质量控制上的投资也不充分,而且总是热衷于低价大销量的营销方式,后者被消费者视为投资充分的不完美信号.增强监管无法从根本上改变厂商投资不足且追逐大销量的现状,但能增加厂商高投资的可能性、提高产品的平均质量.我们的结论在一定程度上吻合乳品等国内食品企业高速扩张但忽视质量控制的现状. 相似文献

The purpose of this study is to examine the consequences of the financial crisis on the European companies’ in conjunction with earnings management practice. It focuses on financially distressed companies that audited by a big 4 auditor during recession years. The study makes use of discretionary accruals as a proxy for earnings management and studies the influence of big 4 auditor, in order to shed more light on possible causes for shifting earnings. The findings of the study provide evidence that financially distressed companies that audited by a big 4 auditor exhibit lower discretionary accruals. The results reveal that Greek and Spanish companies reduce earnings management manipulation during recession. In contrast, Portuguese, Irish and Italian companies show mixed results. They tend to reduce earnings management practices, but there are reasons that influence managers’ behavior to increase earnings management. The findings of this study can be useful for both investors and standard setting authorities. 相似文献

This paper develops a micro-founded general equilibrium model of the financial system composed of ultimate borrowers, ultimate lenders and financial intermediaries. The model is used to investigate the impact of uncertainty about the likelihood of governmental bailouts on leverage, interest rates, the volume of defaults and the real economy. The distinction between risk and uncertainty is implemented by applying the multiple priors framework to beliefs about the probability of bailout.Results of the analysis include: (i) An unanticipated increase in bailout uncertainty raises interest rates, the volume of defaults in both the real and financial sectors and may lead to a total drying up of credit markets. (ii) Lower exante bailout uncertainty is conducive to higher leverage, which in turn raises moral hazard and makes the economy more vulnerable to expost increases in bailout uncertainty. (iii) Bailout uncertainty affects the likelihood of bubbles, the amplitude of booms and busts as well as the banking and the credit spreads. (iv) Higher bailout uncertainty is associated with higher returns’ variability in diversified portfolios and higher systemic risks, (v) Pre-crisis expansionary monetary policy reinforces those effects by inducing higher aggregate leverage levels. (vi) The larger the change in bailout uncertainty and the change in aversion to this uncertainty, the stronger the pre-crisis buildup and the deeper the ensuing crisis.A central policy implication of the analysis is that the vaguest is bailout policy prior to a crisis, the lower is the magnitude of investments destroyed or missed due to errors in evaluating bailout and other intervention policies. On the other hand, the clearer is bailout policy upon the eruption of a crisis, the smaller the contraction of credit and the destruction of investment activity. 相似文献
