Abstract: We propose a methodology to estimate structural models of product line competition. This methodology enables researchers to estimate demand systems accounting for the endogeneity of product introductions, an issue which is typically ignored in the empirical literature in marketing and economics. In particular, we find that not accounting for this form of endogeneity leads to overoptimistic estimates of total demand due to sample selection bias. More importantly, biased estimates of demand can generate misleading managerial recommendations and inaccurate inferences about consumer welfare. In addition, the formulation of a structural model of product line competition enables a researcher to consider policy simulations aimed at studying the consequences of changes in a number of structural factors, such as consumer preferences, cost structure, ownership and capacity.

The model under analysis jointly considers the interplay between consumer preferences, pricing and product line decisions. Consumer demand is characterized by a utility maximization process with unobserved heterogeneity in consumer preferences. Price decisions are assumed to be the outcome of a Bertrand-Nash game among firms
offering differentiated products. Product line decisions are modeled using a Bayesian-Nash equilibrium concept where firms form beliefs about the profits of their competitors and anticipate the prices and demand they would observe for any given set of products that could be introduced in the market.

Resumen: Coastal engineering and coastal zone management are my primary research interests, and I have extensive experience performing surveys of coastal disasters and coastal processes in developing nations, including nations in Asia and Africa. I am currently studying coastal disasters caused by tsunamis and storm surges. Our team has performed field surveys of various coastal disaster areas, including those affected by the Indian Ocean tsunami in 2004, Hurricane Katrina in 2005, the Central Java tsunami in 2006, Cyclone Sidr in Bangladesh in 2007, Cyclone Nargis in Myanmar in 2008, and the Samoan Islands tsunami in 2009. We have also performed numerical simulations of the tsunami and storm surges that occurred in these events and discussed future countermeasures to prevent coastal disasters.

Abstract: Dado cualquier difeomorfismo del círculo, con número de rotación irracional, mostraremos que su medida de probabilidad invariante es la
única distribución invariante. Como una consecuencia mostraremos que el espacio de los cobordes diferenciables reales del difeomorfismo es cerrado
si y solamente si el número de rotación es Diofantino. Mostraremos algunos contraejemplos en dimensión 2 o mayor
