The Labor Market Consequences of Appropriate Technology
Developing countries rely on technology created by developed countries. This paper demonstrates that such reliance increases wage inequality but leads to greater production in developing countries. I study a Brazilian innovation program that taxed the leasing of international technology to subsidize national innovation. I show that the program led firms to replace technology licensed from developed countries with in-house innovations, which led to a decline in both employment and the share of high-skilled workers. Using a model of directed technological change and technology transfer, I find ...

Openness and the Optimal Taxation of Foreign Know-How
Developing countries frequently offer tax incentives and even subsidize the entry and operation of foreign firms. I examine the optimality of such policies in an economy where growth is driven by entrepreneurial know-how, a skill that is continuously updated on the basis of the productive ideas implemented in the country. Openness allows foreign ideas to disseminate inside a country and can foster the country's domestic accumulation of know- how. With externalities, however, laissez-faire openness is suboptimal and can be growth-and even welfare-reducing. I examine the gains from openness ...

A Narrative Analysis of Federal Appropriations for Research and Development
This paper provides a narrative analysis of postwar federal appropriations for the research and development (R&D) activities of the Department of Defense, Department of Energy, National Aeronautics and Space Administration, National Institutes of Health and National Science Foundation—five agencies that consistently account for the vast majority of federal outlays for all types of R&D. We build a novel dataset quantifying the enacted full-year appropriations for all budgetary accounts funding R&D activities at these five agencies over fiscal years 1947-2019. We use this dataset to isolate a ...

The Returns to Government R&D: Evidence from U.S. Appropriations Shocks
We estimate the causal impact of government-funded R&D on business-sector productivity growth. Identification is based on a novel narrative classification of all significant postwar changes in appropriations for R&D funded by five major federal agencies. Using long-horizon local projections and the narrative measures, we find that an increase in appropriations for nondefense R&D leads to increases in various measures of innovative activity, and higher productivity in the long run. We structurally estimate the production function elasticity of nondefense government R&D capital using the SP-IV ...

DO NON-COMPETE COVENANTS INFLUENCE STATE STARTUP ACTIVITY? EVIDENCE FROM THE MICHIGAN EXPERIMENT
This paper examines how the enforceability of employee non compete agreements affects the entry of new establishments and jobs created by these new firms. We use a panel of startup activity for the U.S. states for the period 1977 to 2013. We exploit Michigan’s inadvertent policy reversal in 1985 that transformed the state from a non enforcing to an enforcing state as a quasinatural experiment to estimate the causal effect of enforcement on startup activity. In a difference-in-difference framework, we find little support for the widely held view that enforcement of non-compete agreements ...

The Returns to Government R&D: Evidence from U.S. Appropriations Shocks
Based on a narrative classification of all significant postwar changes in R&D appropriations for five major federal agencies, we find that an increase in nondefense R&D appropriations leads to increases in various measures of innovative activity and higher business-sector productivity in the long run. We structurally estimate the production function elasticity of nondefense government R&D capital using the SP-IV methodology of Lewis and Mertens (2023) and obtain implied returns of 140 to 210 percent over the postwar period. The estimates indicate that government-funded R&D accounts for ...

Based on a narrative classification of all significant postwar changes in R&D appropriations for five major federal agencies, we find that an increase in nondefense R&D appropriations leads to increases in various measures of innovative activity and higher business-sector productivity in the long run. We structurally estimate the production function elasticity of nondefense government R&D capital using the SP-IV methodology of Lewis and Mertens (2023) and obtain implied returns of 150 to 300 percent over the postwar period. The estimates indicate that government-funded R&D accounts for one ...

The Social Returns to Public R&D
Recent empirical evidence by Fieldhouse and Mertens (2024) points to a strong causal link between federal nondefense R&D funding and private-sector productivity growth, and large implied social returns to public R&D investment. We show that these high social return estimates broadly align with existing evidence on the social returns to private or total R&D spending. If the R&D increases authorized under the CHIPS and Science Act were fully appropriated, our modeling indicates a boost in U.S. productivity within a few years, reaching gains of 0.2–0.4% after seven years or more. At their ...

Export Tax Rebates and Resource Misallocation: Evidence from a Large Developing Country
The export tax rebate (ETR) policy is one of the most frequently used policy instruments by Chinese policy makers. This paper therefore provides a vital analysis of its allocation effects. To motivate our empirical analysis for the allocation effects of the ETR policy, we first add a tax rebate to the Melitz and Ottaviano (2008) model and examine the impact of this policy on firms' markup size and resource allocation between eligible and non-eligible firms for the rebates. We use customs transactions, tax administration, and firm-level data to measure the effect of variation in export tax ...
