In this article, we hypothesize that leaders who display group-oriented values (i.e., values that focus on the welfare of
the group rather than on the self-interest of the leader) will be evaluated more positively by their followers than leaders
who do not display group-oriented values. Importantly, we expected these effects to be more pronounced for leaders who are
ingroup members (i.e., stemming from the same social group as their followers) than for leaders who are outgroup members (i.e.,
leaders stemming from a different social group than their followers). We tested our hypotheses in two studies. Results of
a field study (N = 95) showed the expected relationship between leaders’ group-oriented values and followers’ identification with their leaders.
A scenario study (N = 137) replicated the results and extended it to followers’ endorsement of their leaders. Overall, these findings suggest
that displaying group-oriented values pays off more for ingroup than for outgroup leaders. 相似文献

This article investigates the relationship between a debtor country's external financial indicators and the costs associated with the insurance of export credits to that country. For this purpose a stylized model of export credit insurance (ECI) is developed, the central idea being that ECI is similar to a contingent claim such as a European put option. Thus, tools from option pricing theory were used to calculate the price of ECI, implying that not only the current financial position but also the volatility of the changes in that position determine such costs. The empirical results of a statistical analysis of the premium rates for ECI, applied by a private export credit insurer to seventy-seven developing countries during 1993, provide some support for these hypotheses. In particular, the reserves-over-imports ratio of a debtor country and the volatility of the rates of change of this ratio appear to contribute significantly to the premium rates that apply to that country. Thus, the article provides evidence that option pricing parameters do play role in practical insurance pricing, even if this pricing is not explicitly based on these parameters. Premium rates are set as if an underlying option market operated. Thus, the trade of countries with volatile external financial positions is saddled with higher costs than that of countries with more stable positions. 相似文献

EXCHANGE RATE MISALIGNMENT IN DEVELOPING COUNTRIES 总被引:4,自引:0,他引:4
This article analyzes the theory of equilibrium real exchangerates and defines misalignment as a deviation of the real exchangerate (RER) from its equilibrium level. The role of macroeconomicpolicies is then analyzed under three alternative nominal exchangerate regimes: predetermined nominal exchange rates, floatingnominal rates, and dual or black market nominal exchange rates.This discussion points out how inconsistent macroeconomic policiesoften lead to real exchange rate misalignment. Corrective measures,including nominal devaluations and several alternative approaches,are then evaluated. 相似文献

This paper uses a multi-currency approach to analyze the relationship between forward exchange rates, future spot rates and new information. The empirical results tend to support the hypothesis that the exchange rate can be expressed as a function of factors known in advance and ‘news’. 相似文献

The over performance of hedge funds until the current financial market turbulences led to a large number of insurers increasing their hedge funds quota. In the following this asset class is examined and particularly analyzed with respect to its adequacy for an insurance company's asset allocation by focusing on the axiom of safety, as demanded by national law. The problem of survivorship-bias and the Markowitz requirements of normal-distribution and constant correlations among the asset classes and their impact on a strategic asset allocation are studied. 相似文献

The intertribal Musket wars that spread throughout Māori society in the 1820s and 1830s have received much attention from historians. This is also true of the history of trade between New South Wales and New Zealand occurring at the same time. However, at present, the link between these two phenomena remains poorly established. This article draws on the primary material available about the trans-Tasman arms trade from a relatively untapped source, Sydney newspapers, revealing the surprising extent of this commerce and the fact that firearms imports peaked in the early 1830s. This information necessarily requires revision of our understanding of the Musket wars themselves. 相似文献

In this paper I analyze the London Monetary and Economic Conference of 1933, an almost forgotten episode in U.S. monetary history. I study how the Conference shaped dollar policy during the second half of 1933 and early 1934. I use daily data to investigate the way in which the Conference and related policies associated to the gold standard affected commodity prices, bond prices, and the stock market. My results show that the Conference itself did not impact commodity prices or the stock market. However, it had a small effect on bond prices. I do find that the events associated with the abandonment of the gold standard impacted prices in a significant way, even before the actual monetary and currency channels were at work. These results are consistent with the “change in regime” hypothesis of Sargent (1983). 相似文献

Economists’ faith that variable exchange rates benevolently equilibrate has been empirically disconfirmed. That faith is here tackled at its theoretical core with an exchange rate model that although ultra abstract, includes the undeniable fundamentals of market power and differential goals of central bankers and large-scale private players. It permits a game theoretic analysis under the assumption that all agents maximize their payoffs. The paper then relaxes the assumption of maximising agents, allowing for a more complex and thus realistic second version of the model that is interpretable within SKAT, the Stages of Knowledge Ahead Theory of risk and uncertainty. In an experimental setting, this second version of the model points to: a) the inability of agents in central banks, governments and the private real and financial sectors to operate in maximising ways; b) destructive central bank conflict; and c) the widely discrepant outcomes arising from the dynamics of individual personality differences. The paper’s theoretical and empirical findings thus both point to the merits of a single world currency. 相似文献

Namibia has a long history of providing a universal and non-contributory old age pension, child grants using means testing and quasi-conditionalities, and other cash transfers. Multivariate analysis presented in this paper confirms that these transfers play an important role in alleviating poverty, especially for the very poor. The poverty-reducing effects of the child grants are likely to increase further as access is being rapidly expanded. However, the impact in terms of reducing Namibia's extremely high inequality is limited. The targeting of the cash transfers towards the poorest groups takes place through two main channels. For the child grant, targeting occurs as a result of the orphan status eligibility criteria, as orphans are over-represented in lower-income households. For the universal social pension, it appears that some of the relatively less poor do not receive it even if they are eligible. Means testing of child grants appears ineffective, even without considering administrative costs. 相似文献
