This paper extends the work by Morris and Shin (Am. Econom. Rev. 88 (1998) 587-597) where multiple equilibria in the self-fulfilling currency attack models can be reduced to a unique equilibrium when agents observe fundamentals privately with small errors. We find that under a more general specification with realistic parameters, noisy private observations are generally insufficient to prevent the multiplicity of equilibria. The pivotal role played by the transparency of fundamentals/policies in currency crisis is also examined. Surprisingly, transparency may trigger rather than eliminate currency crises when fundamentals are relatively healthy. Our results may be relevant to research in other coordination problems.  相似文献

Using a stochastic frontier methodology that incorporates Bayesian statistics, this paper analyzes the cost efficiency of real estate investment trusts (REITs) by observing the deviations of the measured costs of individual REITs from a defined efficient cost frontier. Using 1995–1997 data, we extend the previous research in this area and measure REIT efficiency more precisely by isolating random measurement error from the overall deviations from the efficient cost frontier. We calculate the magnitude of each REIT's managerial inefficiency, the industry inefficiency, and returns to scale. In addition, we assess specific characteristics of REITs for their contribution to inefficiency by calculating the odds ratio that a REIT with a specific characteristic is more efficient than a REIT with an alternative characteristic. The results show that, for the years studied, REITs are relatively cost efficient with most REITs facing increasing returns to scale. Additionally, the REIT's use of debt and the REIT's management style significantly affect the cost performance of REITs during the aforementioned time period. Finally, diversification across property types, as measured, does not seem to influence REIT cost efficiency.  相似文献

A moneyness‐based propensity to sell (MPS) measure, at the aggregate level, determines the propensity of option holders to exercise their winning relative to losing positions. Using data on individual stock and S&P 500 Index options, we find that the MPS measure has significant predictive power over the cross section of delta‐hedged option returns. We test the disposition effect in the options market based on a long–short strategy that exploits price distortions induced by the disposition bias. More pronounced evidence of the disposition bias is found for individual at‐the‐money call options than put options where the significance of abnormal returns remains robust across different subsamples even after we control for the portfolio option greeks and market‐based risk factors. The profitability of the long–short strategy is related to limit‐to‐arbitrage proxies suggesting that behavioral explanations help explain the positive relation between the MPS measure and delta‐hedged option returns.  相似文献

Based on helping dozens of military veterans refine their ideas for starting a business, we identify and discuss a series of potential pitfalls that aspiring entrepreneurs—veterans and civilians alike—must avoid in order to be successful. Potential entrepreneurs must not confuse the pursuit of hobbies and self-employment with the act of creating a business. People who wish to build a business around public speaking or consulting need to firmly establish why customers should be willing to pay for their advice. Individuals that seek to develop a new non-profit organization must have a viable value proposition even though they are not pursing a profit motive. Overall, the entrepreneurial ventures that are most likely to succeed are those that (1) are based on a sustainable business model, (2) leverage the entrepreneur's unique experiences and attributes, and (3) are built around a process or system that enables the venture to prosper even if the entrepreneur leaves the venture.  相似文献

Data envelopment analysis (DEA) has been constantly used to measure the technical efficiency of decision-making units (DMUs). However, the major problem of traditional DEA methods is that they do not consider the possible intermediate effects. Recently, many papers have applied network DEA models to evaluate the efficiency scores. However, the linking activity of DMUs is still hard to be recognized. Hence, we employ DEMATEL to obtain the linking activity of DMUs. Our empirical research shows that the proposed method can soundly deal with the purpose of identifying the relationship between variables and derive the reasonable result in network DEA.  相似文献

This paper develops an ethical framework for responsible finance and then applies it to Citigroup (Citi), a major financial actor in the microfinance sector, to see whether it meets with such obligations. The framework consists of two categories of responsibility. The first category is the special social responsibility of financial institutions; and the second is the fundamental principles of ethical behavior in financial services. From Citigroup’s microfinance model, scope of business, and multiple roles in the market, the company seems to be fulfilling its responsibility in inclusive finance. However, judged in term of the principles of integrity, objectivity, fairness, professionalism, and diligence, it falls short of its ethical responsibility. In view of this shortcoming, Citigroup should recall its obligation to avoid conflicts of interest, to provide responsible advice, to protect clients from over-indebtedness, and most importantly, to act with integrity.  相似文献

We present a model of central bank collateralized lending to study the optimal choice of the haircut policy. We show that a lending facility provides a bundle of two types of insurance: insurance against liquidity risk as well as insurance against downside risk of the collateral. Setting a haircut therefore involves balancing the trade-off between relaxing the liquidity constraints of agents on one hand, and increasing potential inflation risk and distorting the portfolio choices of agents on the other. We argue that the optimal haircut is higher when the central bank is unable to lend exclusively to agents who actually need liquidity. Finally, for a temporary surprise drop in the haircut, the central bank can be more aggressive than when setting a permanent level of the haircut.  相似文献

This study examines the effect of downstream firms’ (i.e., customers’) risk factor disclosures contained in annual reports on the investment efficiency of upstream firms (i.e., suppliers). We find that more informative disclosures of customers’ risk factors are associated with less under‐ or overinvestment by suppliers. In addition, this inverse association is stronger when the suppliers are at a bargaining disadvantage, when they operate in the durable goods industries, and when they are more concerned about the volatility of future demand. Overall, our results suggest that risk factor disclosures provided by firms in their annual reports contain useful information that could potentially help their suppliers achieve better investment efficiency.
