Does academic economic research produce material of scientific value, or are academic economists writing only for clients and peers? Is economics scholarship uniquely insular? We address these questions by quantifying interactions between economics and other disciplines. Changes in the impact of...

Are scientific knowledge flows embodied in individuals, or "in the air"? To answer this question, we measure the effect of labor mobility in a sample of 9,483 elite academic life scientists on the citation trajectories associated with individual articles (resp. patents) published (resp. granted)...

From its 1958 origin in defense, the Advanced Research Projects Agency (ARPA) model for research funding has, in the last two decades, spread to other parts of the US federal government with the goal of developing radically new technologies. In this paper, we propose that the key elements of the...

Whereas recent research has demonstrated how disinterested social validation may skew valuation in meritocratic domains, interested promotion may be at least as important a factor. As suggested by research on reputational entrepreneurship, a producer's death shifts promotion opportunities in two...

Considerable evidence suggests that information is acquired more easily within than across firm boundaries. I explore why this is observed in the setting of clinical development. Since the mid-1980s, pharmaceutical firms have partly contracted out the operational aspects of clinical trials to...

Academic Medical Centers (AMCs)—comprising medical schools, teaching hospitals, and research laboratories—play an important role in US biomedical innovation. The Balanced Budget Act of 1997 changed reimbursements for Medicare inpatient claims and subsidies for medical residents. We compare...

A rich literature argues that interorganizational networks foster learning and coordinated adaptation among their constituents, but embedded ties between organizations are not ubiquitous. What explains this heterogeneity? Acknowledging the influence of agency relationships within organizations...

We examine the role of network effects in the demand for pharmaceuticals at both the brand level and for a therapeutic class of drugs. These effects emerge when use of a drug by others conveys information about its efficacy and safety to patients and physicians. This can lead to herd behavior...

In a market context, a status effect occurs when actors are accorded differential recognition for their efforts depending on their location in a status ordering, holding constant the quality of these efforts. In practice, because it is very difficult to measure quality, this ceteris paribus...

To what extent does "false science" impact the rate and direction of scientific change? We examine the impact of more than 1,100 scientific retractions on the citation trajectories of articles that are related to retracted papers in intellectual space but were published prior to the retraction...
