Background: An increasing number of container and chassis staging, "dray-off", drop yard, and depot facilities are being established outside of North American marine container terminals. The increased use of these "second-tier" facilities implies that there must be some capacity, delivery time,...

We compare the ability of correlation and threshold effects in a stochastic volatility model to capture the asymmetric relationship between stock returns and volatility. The parameters are estimated using maximum likelihood based on the extended Kalman filter and uses numerical integration over...

We study the ability of traditional diagnostic tests and LM and CUSUM structural break tests to detect a range of different types of breaks in GARCH models. We find that Wooldridge's (1990) robust LM tests for autocorrelation and ARCH have no power to detect structural breaks in GARCH models....

In the midst of the current financial crisis the economics profession has seen a monumental resurrection of Keynesian ideas. The debate, which Keynes started back in the 1930s, is being picked up again, not where it left off, but in exactly the same place it started. While Keynesian theories...

The economics profession not only failed to predict the recent financial crisis, but has been struggling in its aftermath to reach a consensus on the cause(s) of the crisis. While competing narratives are being offered and evaluated, the narrow scope of the debate on strictly technical aspects...

We analyze the puzzling behavior of the volatility of individual stock returns over the past few decades. The literature has provided many different explanations to the trend in volatility and this paper tests the viability of the different explanations. Virtually all current theoretical...

The San Vicente volcano in central El Salvador has a recurring and destructive pattern of landslides and debris flows occurring on the northern slopes of the volcano, and in recent memory, there have been at least seven major destructive debris flows. There has been no known attempt to study the...
