This paper develops a real option model in which the interaction between debt, liquidation policy and risky investments is studied. We consider a manager who owns the firm and faces the opportunity to invest in risky projects which may boost current profits at the cost of bankruptcy if they turn out to be unsuccessful. These investments are “last resort gambles” in the sense that, if successful, they save the company from insolvency, while, if unsuccessful, they make liquidation unavoidable. It is shown that last resort gambles delay liquidation. We study how the liquidation trigger and the last resort investment decisions are affected by the firm's capital structure.  相似文献

Major DAC donors are widely criticized for weak targeting of aid, selfish aid motives, and insufficient coordination. The emergence of an increasing number of new donors may further complicate the coordination of international aid efforts. At the same time, it is open to question whether new donors (many of which were aid recipients until recently) are more altruistic and provide better targeted aid according to need and merit. Project-level data on aid by new donors, as collected by the AidData initiative, allow for empirical analyses comparing the allocation behavior of new versus old donors. We employ Probit and Tobit models and test for significant differences in the distribution of aid by new and old donors across recipient countries. We find that, on average, new donors care less for recipient need than old donors. New and old donors behave similarly in several respects, however. They disregard merit by not taking the level of corruption in recipient countries into account. Concerns that commercial self-interest distorts the allocation of aid seem to be overblown for both groups.  相似文献

Ambiguity about the chances of winning represents a key aspect in lotteries. By means of a controlled field experiment, we exogenously vary the degree of ambiguity about the winning chances of lotteries organized to incentivize the contribution for a public good. In one treatment, people have been simply informed about the maximum number of potential participants (i.e. the number of lottery tickets released). In a second treatment, this information has been omitted as in all traditional lotteries. Our general finding shows that simply reducing the degree of ambiguity of the lottery leads to a sizable and significant increase (67%) in the participation rate. This result is robust to alternative prize configurations.  相似文献

The present research examined the influence of different risk perspectives by the use of four different target persons (who could be affected: abstract person, self, specific person, and specific others) and of four different questionnaire answer formats (rating, open percentage, open, and closed frequency) on risk assessments. It was assumed that subjects use two different systems in terms of probabilistic reasoning: a distributional approach for abstract targets leading to higher risk estimates and a singular approach for specific targets leading to lower risk assessments. According to unrealistic optimism (UO) research (showing higher risk assessments for an abstract person than for self), the assumption was that risk assessments for a specific (named) target lead to lower risk assessments compared to an abstract target. Further, common quantitative answer formats for assessing risk were compared to explore differences in risk estimates. The hypotheses were tested using data of a sample of 512 students from a Bavarian university. The frequently confirmed finding of UO could be replicated with both rating scale and open frequency scale, which appeared to be more sensitive compared to the other used scales. However, UO disappeared when the comparison target was specific. Further, risk assessments for an abstract target were highest within every answer format and lowest for specific targets. Furthermore, results revealed that the type of answer format has a moderating effect on the extent of the influence of risk perspective on risk assessments. Overall, this study gives evidence that both the chosen scale and the risk perspective strongly influence risk assessments. Results aim to contribute to the research fields of quantitative assessment of perceived risk. They suggest that probabilistic reasoning in regard to risk not only underlies motivational or cognitive ego-defensive mechanisms but is rather presumably caused by the use of different systems of inferential strategies.  相似文献

In consequence of the growing economic differences between the developing countries themselves, the Government of the Federal Republic of Germany has developed, alongside plans to combat absolute poverty, a concept for cooperation with relatively advanced developing countries. Rainer Offergeld, Federal Minister for Economic Cooperation, explains this concept.  相似文献
