Intereconomics - Only a few years ago, it was a widespread belief that globalisation would trigger processes of democratisation worldwide. However, even old and established democracies such as the... 相似文献

We examine the spillover wealth effects of the Orange County, California bankruptcy announcement in December 1994 on municipal bonds, municipal bond funds, and bank stocks. This bankruptcy is prominent because of unprecedented losses and because it was caused by a highly leveraged derivatives strategy rather than a shortage of tax revenues and excess spending. We find contagion in the bond market with significantly negative abnormal returns for municipal bond funds without direct exposure to Orange County and for non‐Orange County municipal bonds. In addition, our findings suggest the contagion spills over to the common stocks of investment and commercial banks that deal in or use derivatives; however, the equities of banks unexposed to derivatives are not affected. 相似文献

Monitoring the mean and the variance of a stationary process 总被引:3,自引:0,他引:3
We deal with the problem of how deviations in the mean or the variance of a time series can be detected. Several simultaneous control charts are introduced which are based on EWMA (exponentially weighted moving average) statistics for the mean and the empirical variance. The combined X − S2 EWMA chart is extended to time series. Further simultaneous charts are considered. The comparision of these schemes shows that the residual attempt must be favored if a variance change is present. 相似文献

In this paper, we exploit the introduction of the right of local initiatives in the German state of Bavaria in 1995 in order to study the fiscal effects of direct democracy. Our identification strategy combines difference‐in‐differences and regression discontinuity methods: we compare municipal expenditure and revenue between pre‐ and post‐reform periods at population thresholds where the signatures needed to launch initiatives and minimum quorum requirements decrease discontinuously (difference‐in‐discontinuities design). The results suggest that stronger direct democratic institutions lead to an expansion of local government size. 相似文献

In this paper, we present some results on Geometric Asian option valuation for affine stochastic volatility models with jumps. We shall provide a general framework into which several different valuation problems based on some average process can be cast, and we shall obtain closed form solutions for some relevant affine model classes. 相似文献
