This study tests the weak form of efficiency of the Dhaka Stock Exchange (DSE) for daily, weekly and monthly observed and corrected (corrected for thin and non-synchronous trading) returns of DSE General Index (DGEN). The research applies both parametric and nonparametric tests. Results of...

In developed countries, independent central banks control monetary policy. The goals and instruments of monetary policy are taught in every economics course; however, at times theory fails to work perfectly in practice. In our paper, we review the system of inflation targeting applied by the...

To obtain an efficient diffusion process is an intriguing and important issue in the study of dynamical behaviors on real networks. Most previous studies are mainly focused on the analysis based on the random walk strategy, whose entropy rate is bounded by the logarithm of the largest node...

The present study builds upon the seminal work of Engel and West (2005) and in particular on the relationship between exchange rates and fundamentals. The paper discusses the well-known puzzle that fundamental variables such as money supply and interest rate, provide help in predicting changes...

This paper considers the properties of the tests of the null hypothesis of a random walk against the alternative of a stochastic unit root when the data are generated by a process related to, but not exactly equal to, the processes under the null and alternative. The extensive Monte Carlo...

Background: In spite of the course of the economic crisis of 2008, there have not been changes dramatic to the extent that they would strongly alter the behaviour of the trend in the Average Gross Monthly Wages and the Monthly Wage Medians in the Czech Republic. In order to support public and...

Financial bubbles and recent behaviour of the Latin American stock markets

In this document we use the Expectations Survey conducted monthly by the Central Bank of Colombia during the period of October 2003 - August 2012. We find that exchange rate revaluations were generally followed by expectations of further revaluation in the short run (1 month), but by...

The study covers the period 16/3/83 to 31/12/87, using daily futures prices to provide descriptive statistics and statistical tests for a random walk. The study period falls naturally into two periods, the pre-crash and period including the 1987 crash. The random walk hypothesis provides a...

Until recently the Economic Research Centre (ERC) panel at the University of Western Australia published forecasts of future gold prices in The West Australian newspaper. This note assesses the accuracy of these forecasts. The results show that the actual gold price series follows a simple...
