Title: Optimal Taxation and R&D Policies
We study the optimal design of corporate taxation and R&D policies as a dynamic mechanism design problem with spillovers. Firms have heterogeneous research productivity, and that research productivity is private information. There are non‐internalized technological spillovers across firms, but the asymmetric information prevents the government from correcting them in the first best way. We highlight that key parameters for the optimal policies are (i) the relative complementarities between observable R&D investments, unobservable R&D inputs, and firm research productivity, (ii) the dispersion and persistence of firms' research productivities, and (iii) the magnitude of technological spillovers across firms. We estimate our model using firm‐level data matched to patent data and quantify the optimal policies. In the data, high research productivity firms get disproportionately higher returns to R&D investments than lower productivity firms. Very simple innovation policies, such as linear corporate taxes combined with a nonlinear R&D subsidy—which provides lower marginal subsidies at higher R&D levels—can do almost as well as the unrestricted optimal policies. Our formulas and theoretical and numerical methods are more broadly applicable to the provision of firm incentives in dynamic settings with asymmetric information and spillovers, and to firm taxation more generally.  more » « less

    This study analyzes the impact of corruption on the elasticity of R&D investments in sales per worker by firms. In this sense, it built a model of Schumpeterian growth using optimal control theory relating the effects of corruption on demand for R&D. The model results show that corruption negatively affects the R&D demand and long-term rate of technical progress. However, this cost attributes different 'weights' as firms approach the technological frontier. To empirically test this relationship, it was built partial order-฀ frontiers on a sample of 2,000 firms from 40 sectors and 46 countries. Interacting efficiency scores with the corruption index, the less-efficient firms are disadvantaged with corruption in relation to the frontier firms. This pattern is observed in the coefficient of elasticity of R&D investments indicating that corruption leads to different costs, 'favoring' the most efficient firms in relation to the most backward firms.

    Cybersecurity risk presents a significant and growing challenge for firms. Understanding better how firms are defending themselves can help answer important questions about which controls are more effective and whether firms are investing enough in their defenses. Unfortunately, data on firm-level cybersecurity investments have been difficult for researchers to obtain at large scale. This paper describes a method for constructing firm-level cybersecurity posture metrics by aggregating a selection of data on security products tracked in the SWZD Company Information database. Our exploratory analysis demonstrates this dataset's value in enriching cybersecurity research, offering novel perspectives that could shape sector-specific best practices and enable empirical evaluation of security controls.

    Abstract This article introduces a general equilibrium model of endogenous technical change through basic and applied research. Basic research differs from applied research in the nature and the magnitude of the generated spillovers. We propose a novel way of empirically identifying these spillovers and embed them in a framework with private firms and a public research sector. After characterizing the equilibrium, we estimate our model using micro-level data on research expenditures by French firms. Our key finding is that uniform research subsidies can accentuate the dynamic misallocation in the economy by oversubsidizing applied research. Policies geared towards public basic research and its interaction with the private sector are significantly welfare-improving.

    Tax policies are a wide array of tools, commonly used by governments to influence the economy. In this paper, we review the many margins through which tax policies can affect innovation, the main driver of economic growth in the long-run. These margins include the impact of tax policy on i) the quantity and quality of innovation; ii) the geographic mobility of innovation and inventors across U.S. states and countries; iii) the declining business dynamism in the U.S., firm entry, and productivity; iv) the quality composition of firms, inventors, and teams; and v) the direction of research effort, e.g., toward applied versus basic research, or toward dirty versus clean technologies. We give ideas drawn from research on how the design of policy can allow policy makers to foster the most productive firms without wasting public funds on less productive ones.

    This paper describes the adoption of automation technologies by US firms across all economic sectors by leveraging a new module introduced in the 2019 Annual Business Survey, conducted by the US Census Bureau in partnership with the National Center for Science and Engineering Statistics (NCSES). The module collects data from over 300,000 firms on the use of five advanced technologies: AI, robotics, dedicated equipment, specialized software, and cloud computing. The adoption of these technologies remains low (especially for AI and robotics), varies substantially across industries, and concentrates on large and young firms. However, because larger firms are much more likely to adopt them, 12-64% of US workers and 22-72% of manufacturing workers are exposed to these technologies. Firms report a variety of motivations for adoption, including automating tasks previously performed by labor. Consistent with the use of these technologies for automation, adopters have higher labor productivity and lower labor shares. In particular, the use of these technologies is associated with a 11.4% higher labor productivity, which accounts for 20-30% of the difference in labor productivity between large firms and the median firm in an industry. Adopters report that these technologies raised skill requirements and led to greater demand for skilled labor but brought limited or ambiguous effects to their employment levels.
