We study graph estimation and density estimation in high dimensions, using a family of density estimators based on forest structured undirected graphical models. For density estimation, we do not assume the true distribution corresponds to a forest; rather, we form kernel density estimates of...

IPv6 is an inevitable upgrade to Internet Protocol (IP), the underlying protocol uponwhich the Internet is based, and solves many problems with the existing technologyincluding limited address space, performance and security. Although IPv6 has beensupported by products from major vendors for...

Advances in Information Technology have allowed firms to outsource services with different complexity using different governance structures. We survey the functioning of offshore outsourcing in several labor regimes (including the US, UK, Singapore, Mauritius and India). Three essays are then...

In a two-sector general equilibrium model with pollution (arising from production) affecting the productivity, I examine in both autarky and trade equilibria the equivalence between tax and quota, that is, whether they can replace each other to achieve the same environmental goals. I show that...

This paper examines the role of endogenous capital accumulation in the interaction between trade and the environment in a two-country, two-sector model. Atomic households follow a simple rule of saving: higher the real interest rate, higher the saving rate is. In autarky, the real interest rate...

This study uses a gravity framework to model tourism demand for the Caribbean. The basic model is augmented by Linder’s hypothesis—tourist flows are partly determined by the similarity in preferences between the destination and source markets—and climate distance, which measures the gap...
