Vector error-correction models (VECM) are increasingly being used to capture dynamic relationships between financial variables. Estimation and interpretation of such models can be enhanced if zero restrictions are allowed in the coefficient matrices. Specifically, in tests of indirect causality and/or Granger non-causality in a VECM, the efficiency of the causality detection is crucially dependent upon finding zero coefficient entries where the true structure does indeed include zero entries. Such a VECM is referred to as a zero-non-zero (ZNZ) patterned VECM and includes full-order models. Recent advances have shown how ZNZ patterns can be explicitly recognized in a VECM and used to provide an effective means of detecting Granger-causality, Granger non-causality and indirect causality. This paper develops a general approach and framework for I(d) integrated systems. We show that causality detection in an I(d) system can be discovered identically from the ZNZ patterned VECM’s or the equivalent VAR models.

Risk management has undergone a remarkable transformation over the past fifteen years, with most new methods having been designed for the concerns of large institutions operating in well-developed financial markets. This paper addresses a problem faced by smaller institutions operating in emerging markets, namely the significant lack of data. As many risk management techniques are data intensive, this problem may seem insurmountable. This paper introduces a new method, enriched historical simulation, which supplements the data in an emerging market with data from other markets. The principle behind this methodology is that when many markets are considered, the essence of emerging market economies comes to the fore, with local idiosyncrasies being washed out. This principle is illustrated on the problem of estimating Value-at-Risk on the Cyprus and Athens Stock Exchanges.

This paper compares the long-run buy-and-hold returns of privatization initial public offerings (IPOs) to those of the domestic stock markets of respective countries using a sample of 241 privatization IPOs from 41 countries. The evidence indicates that the privatization IPOs significantly outperform their domestic stock markets if the returns are equally-weighted while value-weighted returns show a sharp reduction in performance. However, there are substantial variations in the long-run performance of privatization IPOs across industries, issuing countries, issue period, and the origin of commercial law of the country. This paper also analyzes the cross-sectional determinants of the long-run buy-and-hold returns of privatization shares. The results indicate that the long-run performance of privatization IPOs is significantly related to the proxies of policy uncertainty, consistent with the signaling models of Perotti (1995). Such effects appear to be overwhelming in the earlier post-IPO period, while the traditional market factors become more important as the policy uncertainty disappears over time. The institutional features of the country such as accounting standards, origin of commercial law, and corporate governance scheme also affect the return performance of privatization issues.

Using data from 1993 to 2002 for eight developed and fifteen emerging markets, we find that return correlations, mean-variance spanning, and Sharpe ratio tests support that closed-end country funds (CECF) can mimic their corresponding foreign indices, and that they are more heavily influenced by their corresponding local markets instead of the U.S. market. This implies that U.S. investors, by investing in CECF, can achieve similar international diversification benefits to those achieved by investing directly in the foreign indices. We also document increased correlation between the U.S. market and foreign markets during this period and find no compelling evidence of economically and statistically significant international diversification benefits, as opposed to a pre 1993 period. These findings could be associated with the financial market liberalization that was prevalent during the period

In this paper we present a model for valuing European and American options, which incorporates both default and interest rate risks. We develop a framework that permits evaluation of three kinds of options: (i) options issued by default-free counterparties on risky bonds, (ii) options issued by risky counterparties on default-free bonds and (iii) options issued by risky counterparties on risky bonds — a case where default risk enters at both levels. We show that the price of a put option on a risky discount bond is hump shaped for a European put and monotone increasing for an American put. We also find that the price impact of default risk is less for an American put option than for a European one.
