In this article, I summarize Griliches' contributions to economics and to applied econometrics.

I study the cross sectional variation of stock returns and technological progress using a dynamic equilibrium model with production. In the model, technological progress is endogenously driven by R&D investment and is composed of two parts. One part is product innovation devoted to creating new...

Traditional U.S. industries with higher firm-specific stock return and fundamentals performance heterogeneity use information technology (IT) more intensively and post faster productivity growth in the late 20th century. We argue that elevated firm performance heterogeneity mechanically reflects...

We provide a theoretical model linking firm characteristics and expected returns. The key ingredient of our model is technological shocks embodied in new capital (IST shocks), which affect the profitability of new investments. Firms' exposure to IST shocks is endogenously determined by the...

This paper empirically examines the effects of industrial and geographic innovations on firm-level profitability and stock returns due to spillovers. Using the data of U.S. patents and patent inventors, we propose empirical proxies for industrial and geographic spillovers and find a positive...

The secular decline in safe interest rates since the early 1980s has been the subject of considerable attention. In this short paper, we argue that it is important to consider the evolution of safe real rates in conjunction with three other first-order macroeconomic stylized facts: the relative...
