Investment in R&D is positively associated with the variance of sales growth and, to a lesser extent, employment growth. The magnitude of this effect has not increased in recent decades, however.

This paper presents the first empirical test with German firm level data of a hypothesis derived by Bustos (AER 2011) in a model that explains the decision of heterogeneous firms to export and to engage in R&D. Using a non-parametric test for first order stochastic dominance it is shown that, in...

We empirically analyze the role of different export destinations in the interrelationship between exporting and investments in R&D and fixed capital at the firm level. We employ a simultaneous equation multivariate Tobit model to account for censoring, interdependence, and endogeneity of our...

In this paper we reexamine the relationship between patents and R&D using empirical likelihood estimation. Based on the data of Hall, Griliches, and Hausman (1986) and the specification allowing for endogenous regressors, we found that the contemporaneous effect of R&D is significantly positive,...

This paper examines the transitional dynamics of an R&D-based endogenous growth model with heterogeneous labor and explains the post-war comovement of three variables in the U.S. economy: the skill premium, the share of labor devoted to R&D and the growth rate of labor productivity. This paper...

We present results from quantitative exercises using the Lucas and Romer endogenous growth models, from which we calculate welfare losses from the distortions presented in the Romer model. Moreover, comparing the models to data, we show that an economy governed by the Romer model would attain a...
