This paper uses an empirical connection between real stock market indices of Germany and the USA for forecasting corresponding returns. We are starting from the random walk as the traditional forecasting model in stock market applications, extending it by co-integration. Since the cointegrating...

Se estudió el comportamiento de los activos del mercado argentino en relación al mercado estadounidense (probablemente el más desarrollado del mundo en cuanto a legislación, volumen y liquidez). Se llega a la conclusión de que los retornos de los activos no se distribuyen normamente. Para...

This paper considers a sequence of discrete-time random walk markets with a single risky asset, and gives conditions … selling the next period, with no shorting, and furthermore for weak convergence of the random walk to a Gaussian continuous-time …

The article tests for a random walk in European equity style indexes. After briefly introducing the efficient market hypothesis, equity styles in general and the used statistical techniques (Variance Ratio Test and modified Rescaled Range Test) it is shown that a random walk in European equity...

In this paper, we use the Wall Street Journal poll of FX forecasts to analyze how the group of forecasters form their expectations. One focus is whether forecasters build rational expectations. Furthermore, we analyze whether the group of forecasters can be regarded as homogeneous or...

Despite its important role in monetary policy and finance, the expectations hypothesis (EH) of the term structure of interest rates has received virtually no empirical support. The empirical failure of the EH was attributed to a variety of econometric biases associated with the single-equation...

Exchange rates have raised the ire of economists for more than 20 years. The problem is that few, if any, exchange rate models are known to systematically beat a naive random walk in out of sample forecasts. Engel and West (2005) show that these failures can be explained by the standard-present...

In this paper sequential monitoring schemes to detect nonparametric drifts are studied for the random walk case. The procedure is based on a kernel smoother. As a by-product we obtain the asymptotics of the Nadaraya-Watson estimator and its associated sequential partial sum process under...

In this paper we study the connection between matrix measures and random walks with a tridiagonal block transition matrix. We derive sufficient conditions such that the blocks of the n-step transition matrix of the Markov chain can be represented as integrals with respect to a matrix valued...

Extending the controversial findings from relevant literature on testing the efficient market hypothesis for the U.S. housing market, the results from the monthly and quarterly transaction-based Case-Shiller indices from 1987 to 2009 provide further empirical evidence on the rejection of the...
