How much U.S. technological innovation begins in universities?

Technological progress has been the key to improved living standards, but how and where do new ideas get their start? The answer might give us some insight into how we can support greater innovation. Some suggest universities have been an important source of innovative technology. A look at the people involved in the development of patented technologies can give an idea of how much innovation originates in universities.Technological innovations ; Universities and colleges

On the Sorting of Physicians across Medical Occupations

We model the sorting of medical students across medical occupations and identify a mechanism that explains the possibility of differential productivity across occupations. The model combines moral hazard and matching of physicians and occupations with pre-matching investments. In equilibrium assortative matching takes place; more able physicians join occupations less exposed to moral hazard risk, face more powerful performance incentives, and are more productive. Under-consumption of health services relative to the first best allocation increases with occupational (moral hazard) risk. Occupations with risk above a given threshold are not viable. The model offers an explanation for the persistence of distortions in the mix of health care services offered, the differential impact of malpractice risk across occupations, and the recent growth in medical specialization.performance measurement, moral hazard, incentives, matching, pre-matching investment, career choice, medical specialization

An Empirical Investigation of Gaming Responses to Performance Incentives

This paper studies a particular kind of gaming responses to explicit incentives in a large government organization. The gaming responses we consider occur when agents strategically report their performance outcomes to maximize their awards. An important contribution of this work is to examine whether this behavior diverts resources (e.g. agents' time) from productive activities or whether it simply reflects an accounting phenomenon. We evaluate the efficiency impact of the behavior we identify and find that it has a negative impact on the true goal of the organization.

Making Government Accountable: Lessons from a Federal Job Training Program

We describe the evolution of a performance measurement system in a government job-training program. In this program, a federal agency establishes performance measures and standards for sub-state agencies. We show that the performance measurement system's evolution is at least partly explained as a process of trial-and-error, characterized by a feedback loop: the federal agency establishes performance measures, the local managers learn how to game them, the federal agency learns about gaming and reformulates the performance measures, leading to possibly new gaming, and so on. The dynamics suggest that implementing a performance measurement system in government is not a one-time challenge but benefits from careful monitoring and perhaps frequent revision.

A General Test of Gaming

An important lesson from the incentive literature is that explicit incentives may elicit dysfunctional and unintended responses, also known as gaming responses. The existence of these responses, however, is difficult to demonstrate in practice because this behavior is typically hidden from the researcher. We present a simple model showing that one can identify gaming by estimating the correlation between a performance measure and the true goal of the organization before and after the measure has been activated. Our hypothesis is that gaming takes place if this correlation decreases with activation. Using data from a public sector organization, we find evidence consistent with our hypothesis. We draw implications for the selection of performance measures.Performance Incentive, Performance Measurement, Gaming, Multitasking, Government Organization.

Performance Incentives with Award Constraints

This paper studies the provision of incentives in a large U.S. training organization which is divided in about 50 independent pools of training agencies. The number and the size of the agencies within each pool vary greatly. Each pool distributes performance incentive awards to the training agencies it supervises, subject to two constraints: the awards cannot be negative and the sum of the awards cannot exceed an award budget. We characterize the optimal award function and derive simple predictions about how award prizes should depend on the number of agencies, on their sizes, and on their performances. Our results indicate that the constraints on the award distribution bind and reduce the overall efficiency of the incentive system.Performance Incentive, Limited liability, Fixed Award Budget, Government Organization.

LABOR MOBILITY OF SCIENTISTS, TECHNOLOGICAL DIFFUSION, AND THE FIRM’S PATENTING DECISION

We develop and test a model of the patenting and R&D decisions of an innovating firm whose scientist-employees sometime quit to join or start a rival. In our model, the innovating firm patents to protect itself from its employees. We show theoretically that the risk of a scientist's departure reduces the firm’s R&D expenditures and raises its propensity to patent an innovation. We find evidence from firm-level panel data that is consistent with this latter result. Our results suggest that scientists' turnover is associated with cross-industry patenting variation and with recent economy-wide increases in patenting. Scientists’ turnover may also partly account for why small firms have high patent-R&D ratiosLabor market for scientists and engineers, patents, research and development, job turnover, mobility of scientists, technological diffusion

Research Scientist Productivity and Firm Size: Evidence from Panel Data on Investors

It has long been recognized that worker wages and possibly productivity are higher in large firms. Moreover, at least since Schumpeter (1942) economists have been interested in the relative efficiency of large firms in the research and development enterprise. This paper uses longitudinal worker-firm-matched data to examine the relationship between the productivity of workers specifically engaged in innovation and firm size in the pharmaceutical and semiconductor industries. In both industries, we find that inventors' productivity increases with firm size. This result holds across different specifications and even after controlling for inventors' experience, education, the quality of other inventors in the firm, and other firm characteristics. We find evidence in the pharmaceutical industry that this is partly accounted for by differences between how large and small firms organize R&D activities.Patents; Innovation; Labor productivity; Research; Firm size
