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...

This paper defines economic slumps as sequences of structural breaks exhibiting a specific pattern. We identify 58 such episodes between 1950 and 2008 among 138 countries, and then examine the phases of decline and their duration. In some countries declines last extremely long, and we put...

This paper investigates how precisely short-term, job-search oriented training programs as opposed to long-term, human capital intensive training programs work. We evaluate and compare their effects on time until job entry, stability of employment, and earnings. Further, we examine the...

This study investigates whether young unemployed graduates who accept a job below their level of education accelerate or delay the transition into a job that matches their level of education. We adopt the Timing of Events approach to identify this dynamic treatment effect using monthly calendar...

Is work overload a friction to public agencies? Using data on R&D procurements, patents, and contracting units from a US federal agency, we investigate how officer workload impacts innovation procurement outcomes. Unanticipated retirement shifts provide an exogenous source of variation that we...

Authority and power permeate political, social, and economic life, but empirical knowledge about the motivational origins and consequences of authority is limited. We study the motivation and incentive effects of authority experimentally in an authority-delegation game. Individuals often retain...

Can standard measures of industrial policy such as R&D subsidies or financial support for machine replacement be effective tools to reverse the current pattern of increasing market power and declining business dynamism? To answer this question we explore the effects of various industrial policy...

Economic societies emerged during the late eighteenth-century. We argue that these institutions reduced the costs of accessing useful knowledge by adopting, producing, and diffusing new ideas. Combining location information for the universe of 3,300 members across active economic societies in...

Debates about the future of work frequently reference past instances of transformative innovation to preface analysis of how automation and artificial intelligence could reshape society and the economy. However, technological shifts in history are rarely considered in depth or used to improve...

In this paper we replicate most of the stylized facts characterizing the decline in business dynamism in the USA highlighted by Akcigit and Ates (2021) and provide an explanation of their emergence by means of a macroeconomic agent-based model populated by two types of firms: innovators who...
