The actual value added tax systems used in many countries differ significantly from the completely general VAT that has been the focus of most economic analyses. In practice, VAT systems exempt broad classes of consumer goods and services. This has important implications for the effect of the...

We estimate the long-term effect of public R&D on growth in manufacturing by analyzing new data from the Cold War era Space Race. We develop a novel empirical strategy that leverages US-Soviet rivalry in space technology to isolate windfall R&D spending. Our results demonstrate that public R&D...

We develop a stylized model that allows us to estimate a value-added measure for nursing homes ("SNFs") which accounts for patient selection both into and out of a SNF. We use the model, together with detailed data on the physical and mental health of about 6 million Medicare SNF patients...

The U.S. Supreme Court decision in the landmark 2018 Wayfair case greatly improved state governments' ability to enforce collection of sales taxes on a destination basis. This has reduced state tax competition with an essentially-untaxed internet, but has brought traditional cross-border...

We show that, in a model without commitment to future policies, geoengineering breakthroughs can have adverse environmental and welfare effects because they change the (equilibrium) carbon taxes. In our model, energy producers emit carbon, which creates a negative environmental externality, and...

We summarize a framework for the study of the implications of automation and AI on the demand for labor, wages, and employment. Our task-based framework emphasizes the displacement effect that automation creates as machines and AI replace labor in tasks that it used to perform. This displacement...

We develop a unified framework to trace value added along global supply chains in the presence of foreign direct investment by decomposing either GDP based on forward linkages or final production based on backward linkages. The new framework accounts for the presence of foreign invested...

We provide a unified framework for measuring bilateral exports of value added. We outline a general methodology that encompasses the measures introduced by Johnson and Noguera (2012) (value added consumed abroad) and Los et al. (2016) (value added in exports), to which we refer as VAX-C and...

This paper examines the impact of government-sponsored venture capitalists (GVCs) on the success of enterprises. Using international enterprise-level data, we identify a surprising non-monotonicity in the effect of GVC on the likelihood of exit via initial public offerings (IPOs) or third party...

This paper provides both a conceptual framework for decomposing a country's gross exports into value-added components by source and a new bilateral database on value-added trade. Our parsimonious framework integrates all previous measures of vertical specialization and value-added trade in the...
