Home bias and deviations from purchasing power parity

Empirical analysis has produced mixed results in testing for PPP. This note presents a simple model linking home bias towards home-produced tradable goods with deviations from absolute PPP. We show that this bias constitutes a significant determinant of PPP deviations.     

Estimates of foreign exchange risk premia: a pricing kernel approach

The goal of this study is to measure market prices of risk and foreign exchange risk premia. Estimations of minimum variance pricing kernels permit to determine market prices of risk, which, in an international no-arbitrage framework, allow to measure foreign exchange risk premia. Market prices of risk are time-varying and surge during financial turmoils. Foreign exchange risk premia are on average small in comparison to interest rate differentials and exhibit significant variation from the early 1970s onwards, when the Bretton Woods exchange rate system collapsed. At times, foreign exchange risk premia dominate interest rate differentials. We are indebted to Baldev Raj, Robert Kunst, the associate editor of Empirical Economics and two anonymous referees for their valuable comments. We also thank seminar participants at the European Central Bank, the Bank of England and Queen Mary University of London.

Nonlinear Exchange Rate Adjustment in the Enlarged Eurozone: Evidence and Implications for Candidate Countries

This paper sheds light on the importance of the validity of PPP hypothesis for the accessing process of the candidate countries towards EMU. The evidence of nonlinear adjustment in real exchange rates suggests the estimation of a nonlinear SETAR model. While linear half‐life estimates are biased upward (five years on average), SETAR half‐life estimates imply a faster reverting process (1.5 years on average). Moreover, we found that TPI‐based real exchange rates are more appropriate than CPI‐based real exchange rates in testing for PPP hypothesis. For the cluster of EMU countries and for the pre‐EMU period, our nonlinear model confirms stationarity for the majority of the TPI‐based real exchange rates with half‐life estimates less than a year.     

Linking trust to use intention for technology‐enabled bank channels: The role of trusting intentions

The present research is an attempt to better understand the role of trust in the adoption of technology‐based service channels, namely Internet and phone banking. The study conceptualizes and measures trust, distinguishing the cognitive and affective component of trust (the trusting beliefs), the behavioral component of trust (trusting intentions), and the purchase behavior (intention to use), suggesting a mediating role of trusting intentions. Then it tests a model that combines the effect of trusting beliefs and trusting intentions together with the Technology Acceptance Model variables, privacy, and security as well as individual characteristics. Results from 762 retail bank customers revealed a strong mediating role of trusting intention on the intention to use and similar patterns of relationship for the two technology‐based bank channels. Several implications for managers and further research are discussed. © 2010 Wiley Periodicals, Inc.     

Is the European Capital Market Ready for the Single Currency?

This paper defines, and investigates the extent of, capital market integration in the European Ecu government bond market sector utilising Johansen's (1992) multivariate analysis. Evidence suggests the yield system is driven by a unique common trend, although we reject the zero-sum restriction on the cointegrating vector. The former finding is consistent with our definition of full Ecu capital market integration, the latter is not, although it is explainable by failure of the expectations hypothesis. Our results support market utilisation of the extant Ecu yield curve as the initial benchmark for pricing euro-denominated debt securities following stage III EMU.     

Adoption and benefits of management accounting practices: Evidence from Greece and Finland

This study investigates the extent to which large-size Greek manufacturing firms have implemented various traditional and currently developed management accounting practices (MAP), the benefits received from those practices and the intentions to focus on specific practices in the future. The findings indicate, that, implementation rates for many currently-developed practices were of a high level and similar than those presented in other countries, in total, traditionally MAP were found to be marginally higher implemented than the currently developed ones. However, there is an increasing trend for firms to place greater emphasis in the future on currently developed techniques instead the traditional ones, particularly on performance evaluation techniques. The results of this survey are compared to the findings of a similar study in Finland.     

Commonality in equity options liquidity: evidence from European Markets

This paper examines commonality in liquidity for individual equity options trading in European markets. We use high-frequency data to construct a novel index of liquidity commonality. The approach is able to explain a substantial proportion of the liquidity variation across individual options. The explanatory power of the common liquidity factor is more pronounced during periods of higher market-wide implied volatility. The common factor's impact on individual options' liquidity depends on options' idiosyncratic characteristics. There is some evidence of systematic liquidity spillover effects across these European exchanges.     

Implied Foreign Exchange Risk Premia

This paper uses implied volatilities from foreign exchange option prices and the results of no‐arbitrage theory to estimate foreign exchange risk premia. In particular, under the assumption of no‐arbitrage, the foreign exchange risk premium is driven by the difference between investors’ market prices of risk in the two currencies. In an international economy with three currencies, sterling, US dollar and Deutschemark, we can use the information on implied volatilities of the three cross rates to derive estimates of implied or ex ante market prices of risk and of foreign exchange risk premia. The foreign exchange risk premia estimates are then compared to survey‐based risk premia.
