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...

The past century witnessed a dramatic improvement in public health, the rise of modern medicine, and the transformation of the hospital from a fringe institution to one essential to the practice of medicine. Despite the central role of medicine in contemporary society, little is known about how...

This paper discusses the relationship between medical innovations and ageing from a health economics perspective and surveys empirical evidence on medical R&D incentives, R&D costs of pharmaceuticals, and the cost-effectiveness of health innovations. Particular focus is on the endogeneity of...

We explore empirically how capital inflows into the US and financial deregulation within the United States interacted in driving the run-up (and subsequent decline) in US housing prices over the period 1990-2012. To obtain an ex ante measure of financial liberalization, we focus on the history...

U.S. network industry reforms led other countries in the past, but have recently run into difficulties in specific areas. In particular, the U.S. telecommunications sector was hit by a deep crisis and electricity reforms suffered under the California disaster. Part of the explanation for these...

U.S. state-level banking deregulation during the 1980’s mitigated the impact of the China trade shock (CTS) on local economies (states and commuting zones) a decade later, in the 1990s. Local economies, where local banking markets opened up earlier, were also effectively financially more...

This paper describes the privatization program in Italy during the 1990s and puts that policy in the context of macroeconomic adjustment, general market deregulation, and promotion of private investment in the provision of public infrastructure. The wave of state divestitures reached Italy later...

This paper reports on ongoing research on the interactions between product regulation and labor market outcomes. In particular, I summarize work on the employment effects of shop-closing regulation in the retail and other related sectors. Evidence on employment in the retail sector from Germany,...

Open borders imply systems competition. This paper studies the implications of systems competition for the national co mpetition rules. It is shown that an equilibrium where all countries retain their antitrust laws does not exist, since abolishing this law makes it possible for a single country...
