This paper examines the efficiency of the forward yen/dollar market using micro survey data. Conventional tests of unbiasedness do not correspond directly to the zero-profit condition. Instead, we use the survey data to calculate potential profits of individual forecasters based on a natural...

This paper uses daily data to analyze how stock and foreign exchange markets react to terror.The data distinguishes location, type of attack and target, number of casualties, and the number of attacks per day for 639 terror attacks between 1990 and 2003 in which 1212 people in Israel were killed...

The rational expectations efficient market model of the exchange rate has failed empirically. In this paper we develop a model of the exchange rate in which agents use simple forecasting rules. Based on an ex post evaluation of the relative profitability of these rules they decide whether to...

We explore the efficiency of the forward reichsmark market in Vienna between 1876 and 1914. We estimate ARIMA models of the spot exchange rate in order to forecast the one-month-ahead spot rate. In turn we compare these forecasts to the contemporaneous forward rate, i.e., the market's forecast...

This study aims to test the efficiency of the Korean foreign exchange market and examine its determinants through several well-established methodologies based on the forward rate unbiasedness hypothesis and covered interest rate parity. The empirical findings indicate that the currency market...

We report evidence on the profitability and statistical significance among 2,127 technical trading rules. The best rules are found to be significantly profitable based on standard tests. We then employ White's (2000) Reality Check to evaluate these rules and find that data-snooping biases do not...

This article examines the dynamic and stochastic behavior of the beta coefficient (to be referred to as the currency beta) of the unbiasedness hypothesis (UH) in foreign exchange markets. We argue that the dynamics and stochastics of currency betas can be attributed to the dynamic behavior...

In this paper we examine the dynamic and stochastic behavior of the beta coefficient (which will be referred to as the currency beta) of the unbiasedness hypothesis (UH) in foreign exchange markets. We argue that the dynamics and stochastics of currency betas can be attributed to the dynamic...

This paper demonstrates that the estimated parameters in previous research, with wrong signs and absurd sizes, do not indicate market inefficiency and market behavior as they appear to. In the real world where forecasting errors are substantially large, a "correct" or an "unreasonable" parameter...

This paper analyzes the informational efficiency of OTC currency options on the Czech koruna and the Polish zloty correcting for the volatility risk premium and errors-in-variable problems, using state-of-the-art techniques (Chernov 2001). It finds that these markets are more efficient than...
