We assess the Covid-19 pandemic's implications for state government sales and income tax revenues. We estimate that the economic declines implied by recent forecasts from the Congressional Budget Office will lead to a shortfall of roughly $106 billion in states' sales and income tax revenues for...

We analyze wartime prosthetic device patents to investigate how procurement policy affects the cost, quality, and quantity of medical innovation. Analyzing whether inventions emphasize cost and/or quality requires generating new data. We do this by first hand-coding the economic traits...

We explore whether minimum wage increases result in substitution from lower-skilled to slightly higher-skilled labor. Using 2011-2016 American Community Survey data (ACS), we show that workers employed in low-wage occupations are older and more likely to have a high school diploma following...

We analyze wartime prosthetic device patents to investigate how demand and procurement policy can shape medical innovation. We use machine learning tools to develop new data describing the aspects of medical and mechanical innovations that are emphasized in patent documents. Our analysis of...

Innovation is part idea generation and part development. We build a model of "innovating-by-doing," whereby ideas come to practitioners. Successful innovation requires that practitioners' ideas be developed through costly effort. Our model nests existing theories of laboratory research and...

We analyze wartime prosthetic device patents to investigate how demand and procurement policy can shape medical innovation. We use machine learning tools to develop new data describing the aspects of medical and mechanical innovations that are emphasized in patent documents. Our analysis of...

This paper presents results from the fourth year of a multi-year, pre-committed research design for analyzing recent minimum wage changes. Using ACS and CPS data through 2018, we find that relatively large minimum wage increases reduced employment among low-skilled individuals by roughly 2.5...
