A new test for constant correlation is proposed. Based on the bivariate Student-t distribution, this test is derived as Lagrange multiplier (LM) test. Whereas most of the traditional tests (e.g. Jennrich, 1970, Tang, 1995 and Goetzmann, Li & Rouwenhorst, 2005) specify the unknown correlations as...

The misevaluation of risk in securitized financial products is central to understanding the financial crisis of 2007 - 8. This paper characterizes the evolution of factors affecting collateralized debt obligations based on subprime mortgages. A key feature of subprime-mortgage backed indices is...

This paper develops a model of exchange rate dynamics that takes into account speculative positions in foreign and domestic equities in addition to the "standard" positions in short-term riskless deposits. The modeling of cross-country stock holdings is motivated by evidence that a large and...

The misevaluation of risk in securitized financial products is central to understanding the Financial Crisis of 2007-2008. This paper characterizes the evolution of factors affecting collateralized debt obligations (CDOs) based on subprime mortgages. A key feature of subprime-mortgage backed...

We find that exogenous structural shocks caused by terrorist attacks, wars, political turmoil and gold market specific events have a strong role to play in the analysis of dynamic relationships between gold and stock market returns. Our main finding is that the interaction between the gold...

ETFs and index funds have grown at very rapid rates in recent years. Originally launched to track some large liquid indices in developed markets, they now also concern less liquid asset classes such as emerging market bonds. Illiquidity certainly affects the quality of the replication, and in...

Currency carry trading presents a widespread trading strategy and refers to the forward premium puzzle. Investors borrow low-yielding currencies with the aim to invest in high-yielding ones in order to benefit from arbitrage opportunities. This implies that a one-to-one relationship does not...

This paper identifies supply and demand shocks that are specific to the oil-market, and separates them from economy-wide shocks that affect the demand for many asset classes, including oil. The shocks are identified by the sign and magnitude of the correlation between daily oil price percent...

Over the course of the last decade, the price of gold has exploded. Recently, however, prices started to fall again. The reversal of this trend has spurred a heated debate between proponents and opponents of gold as an investment. Using time series analysis, we further examine the role of gold...

This paper provides novel insights into the dynamic properties of variance and semivariance premia. Considering nine international stock market indices, we find consistent evidence of significantly negative total and downside (semi)variance premia of around -15 bps per month. These premia almost...
