The reaction of EU bond and equity market volatilities to sovereign rating announcements (Standard & Poor’s, Moody’s, and Fitch) is investigated using a panel of daily stock market and sovereign bond returns. The parametric volatilities are defined using EGARCH specifications. The estimation results show that upgrades do not have significant effects on volatility, but downgrades increase stock ...

Keith Sill is a senior economist in the Research Department of the Philadelphia Fed. Our economy has become increasingly global. We import and export more than ever before. Yet, three facts about international financial transactions, when taken together, pose a puzzle. First, financial capital moves freely across country borders, at least in the case of the developed countries. Returns on simil...

In general, corporations in high-tech industries pursue Corporate Venture Capital investments for financial and strategic objectives. In particular, a large number of corporations have invested in e-business ventures in order to enhance innovation and entrepreneurship within the firm’s network. The achievement of strategic objectives is often comparatively difficult to measure and may take seve...

This paper evaluates the relative importance of three contagion channels: direct trade, neighborhood effects and financial competition in banking centers. Because these channels are highly correlated, they could easily be confused. However, policy implications are very different depending on the channel and therefore disentangle which channels are more relevant is an important task. This paper ...

Empirical research on European stock markets has shown that they behave differently according to the performance of the leading financial market identified as the US market. A positive sign is viewed as good news in the international financial markets, a negative sign means, conversely, bad news. As a result, we assume that European stock market returns are affected by endogenous and exogenous ...

In the field of financial time series analysis it is widely accepted that the returns (price variations) are unpredictable in the long period [1]; nevertheless, this unappealing constraint could be somehow relaxed if sufficiently short time intervals are considered. In this paper this alternative scenario is investigated with a novel methodology, aimed at analyzing short (local) financial trend...

The paper considers nonparametric estimation of Value at Risk (VaR) and associated standard error estimation for dependent financial returns. Theoretical properties of the kernel VaR estimator are investigated in the context of dependence. The presence of dependence affects the variance of the VaR estimates and has to be taken into consideration in order to obtain adequate assessment of their v...

Financial Globalization and Monetary Policy* The process of financial globalization has significantly altered the environment in which national monetary policy authorities operate. What implications does this have for the design of monetary policy? The question can be properly addressed only in the context of a model where monetary policy interacts with financial market efficiency. This paper i...
