The Calvo contract pricing mechanism has become the most widely accepted microfoundation to the NK Phillips curve but unfortunately predicts that all firms in the economy face the same probability of price change. To better explain the stylized fact this paper relaxes the homogeneous firm...

In this paper we propose a novel methodology for forecasting variance convariance matrices (VCM) using kernel estimates. While the popular Riskmetrics methodology can be seen as a special case of our methodology, the generalisation is significant as it allows the researcher to use a number of...

In this paper, we present a limiting distribution theory for the break point estimator in a linear regression model with multiple structural breaks obtained by minimizing a Two Stage Least Squares (2SLS) objective function. Our analysis covers both the case in which the reduced form for the...

This paper studies interactions between innovation, public capital, and human capital in an OLG model of endogenous growth. Public capital affects growth through productivity, the diffusion rate of new technologies, innovation capacity, and human capital accumulation. Panel data regressions show...

This paper considers a long-term relationship between two agents who undertake costly actions or investments which produce a joint benefit. Agents have an opportunity to expropriate some of the joint benefit for their own use. The question asked is how to structure the investments and division...

This paper argues that corruption in developing countries has deep historical roots; going all the way back to the characteristics of their colonial experience. The degree of European settlement during colonial times is used to di¤erentiate between types of colonial experience, and is found to...
