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...

Over the last decade, the U.S. Medicare program has added new billing codes to enhance the financial rewards for Chronic Care Management and Transitional Care Management. We show that the take-up of these new billing codes is gradual and exhibits substantial variations across markets and...

This paper presents results from the third year of a multi-year, pre-committed research design for analyzing recent minimum wage changes. Using ACS and CPS data through 2017, we find that relatively large minimum wage increases reduced employment among low-skilled individuals by just over 2...

This paper presents results from the first year of a multi-year, pre-committed research design for analyzing recent state-level minimum wage changes. Through 2015 and 2016, we estimate that relatively large statutory minimum wage increases have reduced employment among low-skilled population...

Using variation in federal pandemic-era fiscal aid to states driven by the strength of political representation, we find that incremental pandemic-era fiscal aid to states was most likely to end up in the categories of general administrative service spending and employee pension benefit funding....

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...

In analyses of minimum wages, positive "ripple effects" and subminimum wages are difficult to distinguish from measurement error. Indeed, prior work posits that a simple, symmetric measurement process may underlie both phenomena in Current Population Survey data for the full working age...

This paper advances the use of pre-analysis plans in non-experimental research settings. In a study of recent minimum wage changes, we demonstrate how analyses of medium- and long-run impacts of policy interventions can be pre-specified as extensions to short-run analyses. Further, our...

Over the past decade, organized labor has played a significant role in advocating for minimum wage increases. In this paper, we investigate the effects of minimum wage increases on union membership among individuals in minimum wage intensive industries. Consistent with a "freeriding" hypothesis,...
