Orange County Bankruptcy: Financial Contagion in the Municipal Bond and Bank Equity Markets

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.

Voting requirements, concessions, international side payments and the European Monetary Union

This paper addresses the question of criteria for selection of EMU members. We identify two factors in the decision process: (1) The costs and benefits which the individual countries attribute to alternative EMU arrangements (`hard-core', medium-sized, all EU members), and (2) the binding institutional restrictions, i.e., the distribution of votes in the European Council and the minimum vote requirements. Within this framework the EU countries are assigned to different groups according to their degree of convergence. Based on stability concessions and side payments these groups decide on the final EMU composition. We show that minimum vote requirements can lead to a suboptimal size of the EMU and can threaten the feasibility of a multi-speed monetary union.     

Monitoring the mean and the variance of a stationary process

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.
