Evaluating effects of excess kurtosis on VaR estimates: Evidence for international stock indices

The calculus of VaR involves dealing with the confidence level, the time horizon and the true underlying conditional distribution function of asset returns. In this paper, we shall examine the effects of using a specific distribution function that fits well the low-tail data of the observed distribution of asset returns on the accuracy of VaR estimates. In our analysis, we consider some distributional forms characterized by capturing the excess kurtosis characteristic of stock return distributions and we compare their performance using some international stock indices.

The Effect of Bank Debt Downgrades on Stock Prices of Other Banks

We find that debt downgrades of money center banks elicit negative stock price responses in nondowngraded money center banks. Stock prices of larger regional banks also react to these downgrades. Although downgrades of regional banks evoke negative stock price responses for regional banks in the same geographic region, the importance of geographic region as a factor determining the extent of intra‐industry reactions has diminished since 1989. Our results indicate that the merger and expansion activities triggered by interstate banking have blurred differences between regional and money center banks as interstate banking activity has moved towards nationwide banking     

RIP and the shift toward a monetary union: Looking for a “euro effect” by a structural break analysis with panel data

This paper aims to evaluate how the ex ante real interest rates of Euro area countries have been modified by the introduction of the euro. We use cointegration analysis with endogenous breaks in a panel data context. Our results show that the “euro effect” is significant in our sample and that after the introduction of the euro, the real interest parity (RIP) holds. This last conclusion is due to a decrease in the nominal interest rate differentials rather than to a reduction in goods and services price differentials and in the exchange rate volatility.     

ETHICS AND THE MARKET ECONOMY: INSIGHTS FROM CATHOLIC MORAL THEOLOGY

The ethical dimension of market solutions to problems is often neglected by their proponents. This article examines the market from the standpoint of orthodox Roman Catholic moral theology. It illustrates how Catholic theologians have contributed to thinking about the market, draws attention to Catholicism's positive assessment of entrepreneurship, and outlines paths for future Catholic reflection on the market.
