Recent studies have suggested that accession to GATT/WTO is a complex, difficult, and lengthy process, and such process has lengthened in recent years. Using survival analysis, we find that the applicant's political regime has a significant impact on the time it takes to accede to GATT/WTO. In...

We propose and evaluate a technique for instrumental variables estimation of linear models with conditional heteroskedasticity. The technique uses approximating parametric models for the projection of right hand side variables onto the instrument space, and for conditional heteroskedasticity and...

In 2005, the US Congress challenged the acquisition by CNOOC (a Chinese state-owned enterprise) of Unocal (a US firm). This challenge creates a political barrier for foreign companies to acquire US oil companies. This paper examines the stock price reaction of US oil companies to this political...
