Below replacement fertility is a common problem among the rich countries with far reaching economic and social implications. The problem is more acute in some economically fast growing Asian countries where the fertility decline has been more rapid and the current fertility rates have reached...

I re-examine the inverted-U relationship between competition and innovation (originally modeled and tested by Aghion et al. (2005)) by using data from publicly traded manufacturing firms in the US. I control for the possible endogeneity of competition by using various measures of foreign...

We examine the influence of global and regional factors on the conditional distribution of stock returns from six Asian markets, using factor models in which unexpected returns comprise global, regional and local shocks. The models allow for conditional heteroskedasticity and time-varying...

In this short note I clarify two features of Figure 2.3 in Barro and Sala-i-Martin [2004]. The figure, as it appeared in the first and second editions of the book, is confusing if not wrong. I hope this note will serve as a corrigendum to the figure

We study the relationship between market structure and innovation in the global automobile industry from 1982 to 2004 using the dynamic industry framework of Ericson and Pakes (1995). Firms optimally choose a continuous level of innovation in a strategic and forward-looking manner, while...

I reexamine the inverted-U relationship between competition and innovation (modeled and tested by Aghion et al. (2005)) by using data from publicly traded manufacturing firms in the United States. I control for the possible endogeneity of competition by using a trade-weighted average of industry...

We first estimate a dynamic game for the global automobile industry and then compute a Markov Perfect equilibrium to study the equilibrium relationship between market structure and innovation. The key state variable in the model is the efficiency level of each firm and the market structure is...
