The study analyses the interaction between the trading behaviour of 1,024 moving average and momentum models and the fluctuations of the yen-dollar exchange rate. I show first that these models would have exploited exchange rate trends quite profitably between 1976 and 2007. I then show that the...

The idea of introducing a general financial transaction tax (FTT) has recently attracted rising attention. There are three reasons for this interest: First, the economic crisis was deepened by the instability of stock prices, exchange rates and commodity prices. This instability might be...

We gauge the de-facto capital account openness of the Chinese and Indian economies by testing the law of one price on the basis of onshore and offshore price gaps for three key financial instruments. Generally, the three measures show both economies becoming more financially open over time. Over...

We replicate the study of Tabak & Cajueiro (2007): "Are the crude oil markets becoming weakly efficient over time? A test for time-varying long-range dependence in prices and volatility" published in Energy Economics 29, pp. 28-36. The results have been mostly confirmed. Specifically, we have...

This paper analyses the informational efficiency of the WTI crude oil markets using a recently proposed quantitative measure for market inefficiency. The procedure measures the extent to which observed oil price behaviour deviates from the Random Walk benchmark which represents an efficient...

This paper investigates the informational efficiency of global crude oil markets using a recently introduced quantitative measure for market inefficiency. The methodology assesses the deviation of observed oil price behavior from the Random Walk benchmark, representing an efficient market. The...

In this paper, we investigate the "static and dynamic" return and volatility spillovers’ transmission across developed and developing countries. Quoted against the US dollar, we study twenty-three global currencies over the time period 2005-2016. Focusing on the spillover index methodology,...

This paper constructs an early warning system for currency crises in Nigeria based on selected key macroeconomic indicators. It estimates the probabilities of currency crises as a logistic function of the included variables within the framework of a logit model. Particularly, the extent to which...

Is it common for central banks to intervene in foreign exchange markets in order to influence exchange rates? And if so, is it effective? From a German perspective, these questions seem surprising, since the European Central Bank (ECB) does not intervene in foreign exchange markets-rather, it...
