Abstract. Central banks frequently intervene in foreign exchange markets to reduce volatility or to correct misalignments. Such operations may be successful if they drive away destabilizing speculators. However, the speculators do not simply vanish but may reappear on other foreign exchange markets. Using a model in which traders are able to switch between foreign exchange markets, we demonstrate that while a central bank indeed has several means at hand to stabilize a specific market, the variability of the other markets depends on how the interventions are implemented. 相似文献

Optimal Tariffs and Subsidies and Changes in Market Structure 总被引:1,自引:0,他引:1
The paper presents a unified treatment of optimal trade policy for a small country. The well‐known results for duopoly and competitive markets emerge as benchmark cases of the authors’ model. In addition, it is shown that changes in market structure have nonmonotonic effects on optimal tariffs. The results suggest that the recent reduction of tariffs in eastern Europe is consistent with welfare‐maximizing trade policy in response to the substantial changes in the market structure of these countries. 相似文献

Wives' financial independence gained from their pension may increase the risk of marital dissolution, especially when wives are approaching retirement age (the older wives' independence hypothesis). Applying single and simultaneous equations probit models to data from the Panel Study of Income Dynamics, we investigate the effect of wives' pension holding in 1984 on the risk of subsequent marital dissolution. Results from the single equation model appear to support the older wives' independence hypothesis. However, results from the simultaneous equations model suggest that interpreting the single equation results as a sign of older wives' economic independence may be misleading.

We reconsider the optimal consumption choice of investors who do not tolerate any decline in their consumption rate. We connect the demand behavior of such agents to the behavior of standard time-additive agents. With consumption ratcheting, the investor demands the running maximum of the optimal plan a conventional time-additive investor with lower initial wealth would choose. The analysis is carried out for Lévy processes, in particular for jump-diffusions. We obtain explicit solutions for all Bernoulli utility functions, not only those of CRRA type. 相似文献
