Factors Influencing NCQA Accreditation Decisions of HMOs

This paper describes how National Committee for Quality Assurance (NCQA) accreditation of a managed care plan can be used as a signal of plan quality. A model is then developed examining the factors affecting the probability that a plan will be accredited. Larger and older plans are more likely to be accredited. For-profit plans are also more likely to be accredited. Competition in the marketplace from other accredited plans increases the probability of a plan being accredited. The results indicate that plans that have lower costs of accrediting as proxied by size and age are more likely to be accredited.     

The Changing Rewards to Science: The Case of Biotechnology

Little is known about the form and or magnitude of compensation provided university-based scientists working on firm R&D. This is unfortunate, given the important role that university-based scientists play in R&D, and the growing literature concerning compensation and innovation. This paper sheds some light on these issues by examining the compensation of university-based scientists involved with 52 biotech firms that made an initial public offering between March of 1990 and November of 1992. Although the stock holdings of the university scientists are of particular interest, additional forms of compensation received by the scientists are also examined.We find that approximately 10 percent of the university-based scientists affiliated with these companies hold sufficient options or stock to require disclosure at the time of the public offering. A far larger proportion has an equity position in the firm. In many instances the scientists also receive consulting fees or salary from the firm and enter into licensing agreements with the firm. In addition to providing information concerning the compensation of university-based scientists, the empirical work suggests that the rewards to science can be significantly greater than previous work would suggest.     

WHAT DO WE KNOW ABOUT THE POLITICAL ECONOMY OF ECONOMIC POLICY REFORM?

The recent wave of democratization in developing countries andin formerly communist ones has sparked renewed interest in therelation between politics and economic adjustment. Adjustmentprograms, however well designed in a technical economic sense,are often politically difficult to launch and, once launched,to keep afloat. Success in implementing an adjustment programmay depend on a government's skill in generating political supportand holding off the opposition. This article explores the politicsof economic reform, drawing on country studies by politicalscientists and country specialists, the growing theoreticalliterature by economists, and the findings of a World Bank researchproject on the political economy of adjustment in new democracies.The article examines three broad clusters of variables: institutionalcharacteristics of the political system, aspects of the internaland external economy, and the design of the reform program.It also considers the relevance of political analysis for policymakersand for international financial institutions.      

Productivity and Employment in the Information Economy: What Kaldor’s and Verdoorn’s Growth Laws Can Teach the US

During the last decade of the 20th century the US economy experienced the longest economic boom since World War II. Information and communication technologies (ICT) are seen as one of the main reasons for this development and it is still an open question how ICT will affect growth and employment in the future. To evaluate this process Kaldors growth laws, especially Verdoorns law are reconsidered. It will be discussed which changes in the Verdoorn-Coefficient (VC) and the employment threshold (ET) can be expected due to ICT. Induced technical progress and increasing returns to scale could make future economic growth to be less labor-intensive. A simple OLS estimation using data for the US non-farm sector indicates that the VC increased in the second half of the 1990s. Thus, more output growth is required to keep employment constant.The author gratefully acknowledges the most valuable comments from two anonymous referees and the participants of the Annual Meeting of the Austrian Economic Association (NOeG) at the Vienna University of Economics (WU), May 21–22, 2004.

Does foreign aid really raise per capita income? A time series perspective

Abstract. We analyze the relationship between per capita income and foreign aid. We employ annual data and five‐year averages and carefully examine the time‐series properties of the data. Panel estimations with dynamic feasible generalized least‐squares (DFGLS) show that aid generally has an insignificant or minute negative significant impact on per capita income (particularly in highly aid‐dependent countries). This holds true for countries with different levels of human development and income, as well as for different regions. We also find that aid has a small positive impact on investment, but a significant negative impact on domestic savings (crowding out) and the real exchange rate (appreciation).
