Aggregate implications of innovation policy
In this paper we present a tractable model of innovating firms and the aggregate economy that we use to assess quantitatively the link between the responses of firms to changes in innovation policy and the impact of those policy changes on aggregate output and welfare. We show that, to a first-order approximation, a wide range of policy changes have a long-run impact in direct proportion to the fiscal expenditures on those policies, and that to evaluate the aggregate impact of a policy change, there is no need to calculate changes in firms' decisions in response to these policy changes. ; We ...

Pricing-to-market, trade costs, and international relative prices
International relative prices across industrialized countries show large and systematic deviations from relative purchasing power parity. We embed a model of imperfect competition and variable markups in a quantitative model of international trade. We find that when our model is parameterized to match salient features of the data on international trade and market structure in the US, it can reproduce deviations from relative purchasing power parity similar to those observed in the data because firms choose to price-to-market. We then examine how pricing-to-market depends on the presence of ...

Transitional Dynamics in Aggregate Models of Innovative Investment
What quantitative lessons can we learn from models of endogenous technical change through innovative investments by firms for the impact of changes in the economic environment on the dynamics of aggregate productivity in the short, medium, and long run? We present a unifying model that nests a number of canonical models in the literature and characterize their positive implications for the transitional dynamics of aggregate productivity and their welfare implications in terms of two sufficient statistics. We review the current state of measurement of these two sufficient statistics and ...

Pricing-to-market, trade costs, and international relative prices
Data on international relative prices from industrialized countries show large and systematic deviations from relative purchasing power parity. We embed a model of imperfect competition and variable markups in some of the recently developed quantitative models of international trade to examine whether such models can reproduce the main features of the fluctuations in international relative prices. We find that when our model is parameterized to match salient features of the data on international trade and market structure in the U.S., it reproduces deviations from relative purchasing power ...

Innovation, firm dynamics, and international trade
We present a general equilibrium model of the response of firms' decisions to operate, innovate, and engage in international trade to a change in the marginal cost of international trade. We find that, although a change in trade costs can have a substantial impact on heterogeneous firms' exit, export, and process innovation decisions, the impact of changes in these decisions on welfare is largely offset by the response of product innovation. Our results suggest that microeconomic evidence on firms' responses to changes in international trade costs may not be informative about the implications ...
