In recent decades, the foreign assets and liabilities of advanced economies have grown rapidly relative to GDP, with the increase in gross cross-holdings far exceeding changes in the size of net positions. Moreover, the portfolio equity and FDI categories have grown in importance relative to...

The efficient-market hypothesis (EMH) is one of the most important economic and financial hypotheses that have been tested over the past century. Due to many abnormal phenomena and conflicting evidence, otherwise known as anomalies against EMH, some academics have questioned whether EMH is...

A risk management strategy is proposed as being robust to the Global Financial Crisis (GFC) by selecting a Value-at-Risk (VaR) forecast that combines the forecasts of different VaR models. The robust forecast is based on the median of the point VaR forecasts of a set of conditional volatility...

Consider using the simple moving average (MA) rule of Gartley (1935) to determine when to buy stocks, and when to sell them and switch to the risk-free rate. In comparison, how might the performance be affected if the frequency is changed to the use of MA calculations? The empirical results show...

This paper examines how the size of the rolling window, and the frequency used in moving average (MA) trading strategies, affects financial performance when risk is measured. We use the MA rule for market timing, that is, for when to buy stocks and when to shift to the risk-free rate. The...

We construct estimates of external assets and liabilities for over 140 countries over the period 1970-2004. We describe our estimation methods and present some key features of the data, both at the country and at the global level. We focus in particular on trends in net and gross external...

This paper documents the evolution of international financial integration since the global financial crisis using an updated dataset on external assets and liabilities, covering over 210 economies for the period 1970-2015. It finds that the growth in cross-border positions in relation to world...

This paper has two objectives. First, it reviews the recent dynamics of global imbalances (both “flow” and “stock” imbalances), with a special focus on the shifting position of Latin America in the global distribution. Second, it examines the cross-country variation in external...
