Nonprofits are increasingly present in industries with a large for-profit sector, raising questions about their competitive advantage afforded by the nonprofit tax exemption. We estimate an equilibrium model of market structure for recreation/fitness centers to assess whether nonprofit and...

We analyze a class of linear regression models including interactions of endogenous regressors and exogenous covariates. We show that, under typical conditions regarding higher-order dependencies between endogenous and exogenous regressors, the OLS estimator of the coefficient of the interaction...

When firms engaged in R&D are observably heterogeneous (in size) and policymakers are able to condition policy on the observed heterogeneity, what is the optimal policy? This paper starts with a static two-stage duopoly model of R&D competition with uncertainty and finds it welfare enhancing to...

We present a dynamic duopoly model of R&D with spillovers where industry concentration is endogenous. In our model, firms compete repeatedly in both the product market via Cournot competition and in imperfectly appropriable process R&D. The analysis highlights the effects of spillovers through...

We extend the literature on knowledge spillovers between firms by studying a dynamic duopoly model of R&D. Our analysis highlights the previously ignored welfare effects of spillovers through dynamic changes in industry concentration. In addition, we find that the impact of imperfect...

Using industry level data for Japanese foreign direct investment (FDI) flows to five Asian countries, we investigate how the sensitivity of FDI to the exchange rate changes across different industry types and exchange rate indices. Key results are as follows: (i) aggregated FDI data reported at...
