Computer use and productivity growth in US federal government agencies, 1987-92

Article Abstract:

A study involving interviews and econometric analysis was conducted to examine the influence of computer use on productivity in the public sector from 1987 to 1992. During this period, there was a 47% increase in the number of computers for every employee. A production function for government services that incorporates information technology (IT) capital as an input was formulated. Findings revealed a significant positive relationship between productivity growth and computer-intensity growth, proving the existence of excess returns to IT capital.

Do (more and better) drugs keep people out of hospitals?

Article Abstract:

A model is developed to examine the role of drug use in reducing hospitalization days and mortality. An International Classification of Diseases (ICD9) two-digit disease is used as a unit of analysis. Using data from the 1980 and 1991 National Ambulatory Medical Care Survey, estimates show that a dollar increase in prescriptions for drugs resulted to a corresponding $3.65 reduction in hospitalization costs.
