Information Technology and Medical Missteps: Evidence from a Randomized Trial

Rebitzer, James B.; Javitt, Jonathan C.; Reisman, Lonny - National Bureau of Economic Research (NBER) - 2007

We analyze the effect of a decision support tool designed to help physicians detect and correct medical "missteps". The data comes from a randomized trial of the technology on a population of commercial HMO patients. The key findings are that the new information technology lowers average charges...

Organizational Economics and Physician Practices

Rebitzer, James B.; Votruba, Mark E. - National Bureau of Economic Research (NBER) - 2011

Economists seeking to improve the efficiency of health care delivery frequently emphasize two issues: the fragmented structure of physician practices and poorly designed physician incentives. This paper analyzes these issues from the perspective of organizational economics. We begin with a brief...

HIV and Fertility Revisited

Kalemli-Ozcan, Sebnem; Turan, Belgi - National Bureau of Economic Research (NBER) - 2010

Young (2005) argues that HIV related population declines reinforced by the fertility response to the epidemic will lead to higher capital-labor ratios and to higher per capita incomes in the affected countries of Africa. Using household level data on fertility from South Africa and relying on...

HIV and Fertility in Africa: First Evidence from Population Based Surveys

Juhn, Chinhui; Kalemli-Ozcan, Sebnem; Turan, Belgi - National Bureau of Economic Research (NBER) - 2008

The historical pattern of the demographic transition suggests that fertility declines follow mortality declines, followed by a rise in human capital accumulation and economic growth. The HIV/AIDS epidemic threatens to reverse this path. A recent paper by Young (2005), however, suggests that...

Influence, Information Overload, and Information Technology in Health Care

Rebitzer, James B.; Rege, Mari; Shepard, Christopher - National Bureau of Economic Research (NBER) - 2008

We investigate whether information technology can help physicians more efficiently acquire new knowledge in a clinical environment characterized by information overload. Our analysis makes use of data from a randomized trial as well as a theoretical model of the influence that information...

Organizational Fragmentation and Care Quality in the U.S. Health Care System

Rebitzer, James B.; Cebul, Randall D.; Taylor, Lowell J.; … - National Bureau of Economic Research (NBER) - 2008

Many goods and services can be readily provided through a series of unconnected transactions, but in health care close coordination over time and within care episodes improves both health outcomes and efficiency. Close coordination is problematic in the US health care system because the...

Mortality Change, the Uncertainty Effect, and Retirement

Kalemli-Ozcan, Sebnem; Weil, David - National Bureau of Economic Research (NBER) - 2002

We examine the role of changing mortality in explaining the rise of retirement over the course of the 20th century. We construct a model in which individuals make labor/leisure choices over their lifetimes subject to uncertainty about their date of death. In an environment in which mortality is...

Structuring Incentives Within Organizations: The Case of Accountable Care Organizations

Rebitzer, James B.; Frandsen, Brigham - National Bureau of Economic Research (NBER) - 2014

Accountable Care Organizations (ACOs) are new organizations created by the Affordable Care Act to encourage more efficient, integrated care delivery. To promote efficiency, ACOs sign contracts under which they keep a fraction of the savings from keeping costs below target provided they also...

AIDS, "Reversal" of the Demographic Transition and Economic Development: Evidence from Africa

Kalemli-Ozcan, Sebnem - National Bureau of Economic Research (NBER) - 2006

Using country- and region-level data, I investigate the effect of HIV/AIDS on fertility in Africa during 1985-2000. Results differ depending on the variation used and the estimation method. Between estimates that exploit cross-sectional variation suggest a positive significant effect of HIV/AIDS...
