This paper studies the effects that benefits of control and moral hazard have on the evolution of large stakes in REITs. A large risk-averse shareholder trades off the net benefits of REIT business monitoring and control with the cost of bearing risk beyond the level compensated by the REIT return premium. In equilibrium, the large shareholder gradually adjusts his ownership shares level (as long as his marginal benefits from holding shares increase in his REIT stake) towards the long-run competitive equilibrium in which his marginal share valuation coincides with that of the market. Because of the moral hazard, such level of ownership (and monitoring) is, in general, inefficient. The speed of adjustment is positively correlated with the agents risk aversion and company volatility, and negatively correlated with his marginal benefits of control and beneficial monitoring effects. 相似文献

In this paper we investigate portfolio optimization in the Black–Scholes continuous-time setting under quantile based risk measures: value at risk, capital at risk and relative value at risk. We show that the optimization results are consistent with Merton’s two-fund separation theorem, i.e., that every optimal strategy is a weighted average of the bond and Merton’s portfolio. We present optimization results for constrained portfolios with respect to these risk measures, showing for instance that under value at risk, in better markets and during longer time horizons, it is optimal to invest less into the risky assets.This research was partially supported by the National Science and Engineering Research Council of Canada, and the Mathematics of Information Technology and Complex Systems (MITACS) Network of Centres of Excellence. 相似文献

There are several studies in entrepreneurship investigating determinants of innovation outcomes in SMEs. Although entrepreneurs’ entrepreneurial creativity is often seen as a prerequisite, previous research indicates it is not an exclusive determinant of innovation. We use theoretical logics of social cognitive theory and innovation theory to develop a conceptual model of entrepreneur’s creativity, self-efficacy, and innovation outcomes. The model is then tested on a large sample of small and medium firms from two distinct economies: the United States and Slovenia. Empirical findings partially support the proposed moderation effects of entrepreneurial self-efficacy, but with the same variations between countries. The implications of these results in relation to entrepreneurship theory and practice are discussed. 相似文献

We study how group membership affects behavior both when group members can and cannot interact with each other. Our goal is to isolate the contrasting forces that spring from group membership: a free‐riding incentive leading to reduced effort and a sense of social responsibility that increases effort. In an environment with varying task difficulty and individual decision making as the benchmark, we show that the free‐riding effect is stronger. Group members significantly reduce their effort in situations where they share the outcome but are unable to communicate. When group members share outcomes and can interact, they outperform groups without communication and individuals. We show that these groups do as well as the best constituent member would have done on his or her own. 相似文献

We estimate capital flight from seven countries of the Commonwealth of Independent States for the period 1995–2005. In some
countries capital flight is large and growing, but other countries, despite similar macroeconomic and political circumstances,
have little capital flight. We develop a model of capital flight that incorporates costs of moving money to offshore locations
and show that such costs are an important determinant of capital flight. Liberalizing the trade and financial sectors accelerates
capital flight by making it easier to move capital abroad. In the short run, greater regulation rather than external sector
liberalization appears to have more potential to combat capital flight. 相似文献

In this article, we search for the evidence of intraweek and intraday anomalies on the spot foreign exchange (FOREX) market. Having in mind the international scope of this market, empirical evidence against market efficiency (i.e. market anomalies) will have important consequences for the substantial number of FOREX investors all around the globe. We explore intraweek, intraday and interaction between days and hour trade anomalies on the FOREX market over the period of 10 years using hourly time-series data of Euro and US Dollar (EUR/USD) exchange rate on Swiss FOREX market from 1 January 2004 to 11 January 2014. We compare by analysis of variance test all pairs of mean returns on a daily, hourly and daily/hourly basis. t-Test is used to test whether intraday returns are significantly different from zero. We employ Tukey’s honestly significant difference test to explore which intraday pairs of hourly mean returns are significantly greater than zero. We find that intraday and interaction between day and hour anomalies are present in trading EUR/USD on the spot FOREX market over the period of 10 years. The best arbitrage opportunity is evidenced on Fridays, when selling USD and buying EUR at 00:00 and selling EUR and buying USD at 03:00 the same day. 相似文献

Results of two experiments reveal that the use of probability markers in advertisements affects brand attitude and purchase intentions, and that this is moderated by the type of service, customers’ involvement, and their level of tolerance for ambiguity. Services in the study were classified as more or less hedonic/utilitarian, and more or less involving. Probability markers affect consumers’ brand attitude and purchase intentions for less-involving services, while this effect is not significant for more-involving services. In addition, higher tolerance for ambiguity results in preference of hedges over pledges or no probability markers, while for consumers with lower tolerance for ambiguity the opposite holds. With regards to service type, for more-hedonic, less-involving services the use of hedges in advertising copy increases brand attitude and purchase intentions, while for more-utilitarian, less-involving services pledges result in highest levels of brand attitude and purchase intentions. 相似文献

Test procedures for detection of a change in the distribution of a sequence of independent observations based on empirical characteristic functions are developed and their limit properties are studied. Theoretical results are accompanied by a simulation study.The work of the first author was partially supported by grants GAČR 201/03/0945 and MSM 113200008 相似文献
