We study the impact of nine categories of scheduled and unscheduled news announcements on the euro/ dollar return volatility. We highlight and analyze the pre-announcement, contemporaneous and postannouncement reactions. Using high-frequency intraday data and within the framework of ARCH-type models, we show that volatility increases in the pre-announcement periods, particularly before schedule...

The paper examines the economic role of modelling information on the decision problem of an exporting firm under exchange rate risk and hedging. Information is described in terms of market transparency, i.e., a publicly observable signal conveys more information about the random foreign exchange rate. We analyze the interaction between market transparency and the ex ante expected utility of the...

We study the dispersion of absolute price levels for US cities since 1918. By absolute price levels, we mean price indices that measure the cost of a given consumption basket at each point in time. We find strong evidence that city price levels converge over time and that the dispersion of price levels is lower for US cities than between OECD countries. We argue that price level convergence for...

Notwithstanding its widespread use in financial markets and well-documented profitability, technical analysis is still perceived to carry useless information. This paper provides a possible explanation for this puzzle that goes beyond the standard self-fulfilling prophecy argument. If at least some of the asset price fundamentals are not currently observable, the oscillator model is able to inf...

This paper presents a simultaneous model of exchange rates between the US dollar, German mark and Japanese yen. In addition to incorporating long-run equilibria and short-run dynamics, the model is designed to capture complex interaction between currencies not normally considered in exchange rate models. The model is demonstrated to be an economically and statistically superior forecasting tool...

This paper presents a potential solution to the home bias puzzle based on a new open economy macroeconomics model. In response to technology shocks, sticky prices generate a negative correlation between labor income and the profits of domestic firms, leading to home bias in equity holdings. In contrast, under flexible prices, labor income and the profits of the domestic firms are positively cor...

Using the data from a developing country like India, we offer an empirical analysis to examine the relationship between devaluation of the Rupee and the real trade balance with her major trading partners since the liberalization process that began in July 1991. Exploiting the recent advances in panel-data time-series econometrics, we document that devaluation may not be effective in improving t...

This paper extends the real interest differential (RID) model of Frankel (1979) by introducing Markov regime switches for three exchange rates over the years 1973 2000. Evidence of a non-linear relationship between exchange rates and underlying fundamentals is provided. One of the regimes represents exactly the RID case. Decisive fundamentals in determining regimes turn out to be mainly interes...

This paper investigates the effects of temporal aggregation when the aggregation frequency is variable and possibly stochastic. The results that we report include, as a particular case, the well-known results on fixed-interval aggregation, such as when monthly data is aggregated into quarters. A variable aggregation frequency implies that the aggregated process will exhibit time-varying paramet...

This paper analyzes the stability of the exchange rate in an economy with noise traders. Noise trading is restricted to agents investing in the domestic stock market. The agents pricing foreign exchange hold rational expectations. Monetary policy is affected by the behavior of investors in the domestic stock market and in turn affects fundamental stock evaluations as well as noise trading. We s...
