The volatility information found in high-frequency exchange rate quotations and in implied volatilities is compared by estimating ARCH models for DM/$ returns. Reuters quotations are used to calculate five-minute returns and hence hourly and daily estimates of realised volatility that can be included in equations for the conditional variances of hourly and daily returns. The ARCH results show t...

Cumby (1996) suggests that (i) deviations from MacParity are stationary, (ii) relative Big Mac prices converge rapidly and (iii) provide significant information on likely future exchange rate movements. This paper examines to what extent these results can be generalised to other micro-level price data such as those provided in the UBS surveys Prices and Earnings round the Globe. In many respect...

The purpose of this paper is to investigate the ability of parameter instability tests in regressions with I(1) processes to discriminate between changes in the cointegrating relationship and changes in the marginal distribution of the regressors. Using annual data for the G-7 countries and the Purchasing Power Parity, we conclude that the regression coefficient between the price level differen...

This paper proposes a continuous-time framework that explains some stylised facts in recent “twin crises” episodes. I show that access to the world capital market enables the domestic economy to achieve a more efficient allocation of resources. However, the banking sector becomes more fragile when this international borrowing is wealth-constrained. A temporary shock is amplified and becomes per...

The general-to-specific (GETS) approach to modelling is widely employed in the modelling of economic series, but less so in financial volatility modelling due to computational complexity when many explanatory variables are involved. This study proposes a simple way of avoiding this problem and undertakes an out-of-sample forecast evaluation of the methodology applied to the modelling of weekly ...

The application of the generalized gravity model in analyzing the Bangladesh’s trade reveals that Bangladesh’s trade is positively determined by the size of the economies, per capita GNP differential of the countries involved and openness of the trading countries. Bangladesh’s exports are positively determined by the exchange rate, partner countries’ total import demand and openness of the Bang...

In the nineteenseventies, James Tobin suggested the introduction of a transaction tax on the currency market to cope with exchange rate volatility. We investigate the consequences of the introduction of such a tax on an asset market model from a game-theoretic and an experimental point of view. Our main results include in respect to our model that contrary to the situation in game-theoretic equ...

In this paper the optimal choice of a monetary target is investigated for a small open economy that is subject to foreign monetary policy shocks. In contrast to large parts of the literature, pegging the exchange rate is never the best policy choice for the small open economy in our model. Instead, monetary targeting and, depending on the parameter combination, producer price index targeting co...

This paper presents experimental evidence concerned with behavior in indefinite horizon two-person dynamic favor exchange games. Subjects interact in pairs in continuous time and occasionally one of them receives opportunity to provide a favor to her partner. The effects of changing the benefit of receiving a favor and the arrival rate of opportunities to do a favor are studied when the opportu...

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...
