We analyze investment by a population of hyperbolic discounting entrepreneurs. In order to avoid inefficient procrastination, agents with good prospects about their chances of success may choose to forego free information and to invest boldly. This explains an excessive level of investment in the economy. Building on this observation, we show that low risk-free interest rates favor bold entrepreneurship and entry mistakes. Furthermore, public intervention can be socially desirable: Forcing agents to acquire information before deciding whether to invest may reduce competitive interest rates and may be beneficial for all individuals in the economy .

And thus the native hue of resolution Is sicklied o'er with the pale cast of thought, And enterprises of great pith and moment With this regard their currents turn awry, And lose the name of action.                      Hamlet , Act 3: Scene 1.

We construct a dynamic model of corruption in organizations where officials privately know their propensity for corruption and clients optimally choose the bribe offered. We show that there is a continuum set of stationary bribe equilibria due exclusively to the dynamic nature of the model and the endogenous determination of bribes. This can explain why similar countries have stable but different \"implicit prices\" for the same illegal services. We also show that, by not considering the reaction of clients, traditional analysis have systematically overestimated the beneficial effect of increasing wages as an anticorruption measure.  相似文献

One advantage of having an online shopping village attached to your not-for-profit organization's Web site is it gets supporters used to contributing online. If a consumer is willing to purchase over the Web, it's only a short leap to putting donations more directly to work for a favorite cause.  相似文献

Definitions of “political risk” abound, including with “assessments” or “analysis,” but even though ratings are widely used by investors, few understand either the theory behind particular instruments or what the ratings say about their potential investment. The assessment of political risk works backward from losses to foreign investors (not domestic) that could have been insured or protected, to a determination of how high the risk is, what the cost of the likely loss might be, the type of insurance coverage that might be necessary, and then to what an investor should be willing to pay to protect against that risk. A wide range of potential losses and potential causes of those losses is covered by the many political risk assessment firms and indices that are available to potential investors. BERI, the PRS Group, ICRG, the Eurasia Group, PERC (Hong Kong), and many others provide an array of ratings that investors can employ in making their choices. Few of these focus on the critical element of forecasting. Insurance doesn't relate to circumstances of the moment but rather those of the future. What will they be? Just a few of the risk assessments (PRS, BERI, ICRG) deal explicitly with the future, as good as that might be. Few also deal with the matter of risks to particular industries, companies, regions of a country, or external circumstances (what are the country's neighbors up to?). This article offers some suggestions on improving the political risk assessment business. © 2014 Wiley Periodicals, Inc.  相似文献

\"This paper tests a central prediction of vintage growth models of urban structure: that there are discontinuities in the population density function. The data set covers quarter sections in Chicago in 1980. Using such highly disaggregated data is critical because discontinuities are less likely to be found the larger is the unit of observation. Both a switching regression model and a nonparametric estimator reveal discontinuities and upward-sloping segments in the function, which supports the vintage growth model.\"  相似文献
