The classical and early neoclassical economists knew that the essential function of money was its role as a medium of exchange; Recently, this idea has been formalized using search-theoretic noncooperative equilibrium models of the exchange process. The goal of this paper is to use a simple model...

This paper estimates the nature and magnitude of the local externalities from own industry scale, as envisioned by Marshall. Census panel data on individual plants in high-tech and machinery industries across up to 487 countries are utilized, to quantify the direct effects of local external...

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...

This essay offers a brief history of macroeconomics, together with an evaluation of what has been learned over the past several decades. It is based on the premise that the field has evolved through the efforts of two types of macroeconomist-- those who understand the field as a type of...

Following an influential article by Angrist and Krueger (1992) on two-sample instrumental variables (TSIV) estimation, numerous empirical researchers have applied a computationally convenient two-sample two-stage least squares (TS2SLS) variant of Angrist and Krueger's estimator. In the...
