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

This paper suggests an explanation for the heavy trading volumeobserved on the US capital markets, the world's largest. Heterodoxeconomic theory puts much of this volume down to speculation.Mainstream theory tends to support this thesis, either directlyor indirectly, by giving space to the idea that trading activityis for the most part exogenous to the functioning of the capitalmarkets. The central hypothesis of this paper is that the tradingvolumes observed are an endogenous feature of the capital markets,because they are to a great extent determined by the needs ofthe institutional investors who predominate on these markets.This endogeneity of trading is posited in connection with theemergence of a new ‘core–satellite’ paradigmin institutional investment, a development that essentiallymanifests the asset-management industry's transformation froma small industry serving a few wealthy clients to a mass industryserving large sections of the population.  相似文献

This article considers a linear regression model with some missing observations on the response variable and presents two estimators of regression coefficients employing the approach of minimum risk estimation. Small disturbance asymptotic properties of these estimators along with the traditional unbiased estimator are analyzed and conditions, that are easy to check in practice, for the superiority of one estimator over the other are derived.

Two readings are made of Mynatt, Omundson, Schroeder and Stevens (pp. 657–683). The first reading views the paper through a largely “conventional” social science lens, while the second adopts a more critical perspective which raises three issues: abstraction in research; gender and ethnicity; and the rhetoric of research.  相似文献

This article considers the applicability of performance monitoring in the public sector. It analyses performance information across Australian government in order to identify, if possible, the basic attributes of effective performance monitoring, and finds significant variations. The authors conclude that varying levels of complexity in defining ends, and in attributing the achievement of objectives to particular means, may account for most of the differences. However, a number of exceptions suggest there is also room for adaptation.  相似文献

The Coevolution of the Real and Financial Sectors in the Growth Process   总被引:4,自引:0,他引:4  
The role of debt and equity changes over time and with the levelof development. What are these changes, and why should theysystematically occur across different countries and time periods?This article characterizes financial innovation as a dynamicprocess that both influences and is influenced by the developmentof the real sector. It focuses on the emergence and developmentof equity markets, using a model that allows for growth andfor capital accumulation that is financed externally througha combination of debt and equity. As an economy develops, theaggregate ratio of debt to equity will generally fall; yet,debt and equity remain complementary sources for the financingof capital investments. The results suggest how various governmentpolicy actions might affect capital accumulation and equitymarket activity.  相似文献

Cross-sectional and time-series tests using mimicking portfolios are used to assess the exactness of the APT with(out) a residual market factor. The first factor seems to be sufficient to span the efficient set, whether the model is estimated using (un)conditional variance-covariance matrices that are (un)adjusted for nonsynchronous trading. Although the conditional standard deviations of the mimicking portfolios significantly explain the time-variability of security volatilities, the residuals of the mean equation still exhibit heteroskedasticity. Similar results are obtained for portfolios of CAPM-betaranked securities, and for randomly selected individual securities.  相似文献

Annuities promise to play an increasingly important role in countries with national defined contribution retirement systems. In this article we examine life annuities in two countries, Singapore and Australia, each of which has a national mandatory pension program. Exploiting data on annuity pricing and purchase behaviour, we compare the money's worth of life annuity products across these two nations. Our results indicate that, after controlling on administrative loadings, there are important differences in measured adverse selection. Part of the explanation may be due to the different structures of the two countries’retirement systems.  相似文献
