NBER Summer 2006 Reporter Summary

Core Content

The NBER Summer 2006 Reporter provides an overview of the Program on Industrial Organization (IO) and highlights key research areas and policy implications. It features summaries of various studies on regulatory and antitrust policy, pricing behavior in oligopoly markets, and auction markets, as well as insights into the evolution of economic regulation across industries such as electricity, telecommunications, cable television, airlines, pharmaceuticals, and financial services.

Main Research Areas

1. Regulatory and Antitrust Policy

• The IO program focuses on three broad areas: regulation and antitrust policy, pricing behavior by firms, and auction markets.
• Electricity restructuring has been a major topic, with research emphasizing the tension between imperfect competition and imperfect regulation.
  • Studies show that restructuring can lead to increased productivity and efficiency but may also be limited by market power.
  • Incentive-based regulation is increasingly used in place of cost-based pricing, especially in transmission and distribution.
  • Challenges include system investment, reliability, and market integration.
• Telecommunications has seen unbundling and deregulation, but forward-looking cost-based regulation still affects network elements.
  • Research suggests that unbundling may increase competition but also has adverse investment effects.
  • Product differentiation is expected to grow due to local competition.
• Cable television regulation has evolved over time, with price regulation impacting product quality and innovation.
  • Satellite competition raises questions about the need for price regulation.
• Airline deregulation has led to consumer benefits such as lower fares and more flights, but also financial volatility.
  • Legacy airlines face challenges due to increased competition, demand shocks, and rising costs.
  • Government-controlled airports may be a long-term challenge for the industry.
• Pharmaceutical regulation has been a concern for innovation incentives and product launch delays.
  • Regulatory reforms such as user fees and fast-track reviews have reduced approval lags.
  • Price controls may discourage innovation and increase drug prices for non-Medicaid buyers.
• Financial services regulation has evolved from price and entry controls to more flexible frameworks.
  • Asymmetric information and consumer biases may affect market efficiency.
  • Antitrust and IP coordination is essential in innovative sectors.
  • Mergers in highly innovative industries may have dynamic efficiency implications.

Pricing Behavior in Oligopoly Markets

• Price dispersion is common in markets with asymmetric information and search costs.
• Internet retailing has been shown to increase price competition by reducing search costs.
  • Price comparison sites like DealTime.com reduce brand-name retailer dominance.
  • Consumer search behavior is relatively low, with only 5-10% of prescriptions being comparison-priced.
• Online bookstores and automobile markets show price sensitivity and strategic responses by retailers.
  • Internet referrals significantly reduce car purchase prices, especially for minority buyers.
  • Transparency in dealer invoice costs and negotiating power of online services contribute to price reductions.

Auction Markets

• Auction markets have become a key area of economic research, especially with the rise of eBay and online platforms.
• Auctions are studied in various contexts, including government procurement, pollution permits, and timber sales.
  • Auctions are compared with retail markets, with conditions for efficiency being analyzed.
  • Demsetzian auctions are found to welfare dominate duopoly when marginal revenue decreases with quantity.
• Experimental data is used to evaluate auction models and bidding behavior.
  • Structural estimation of auction models is calibrated using experimental data.
  • Secondary resale markets influence bidding behavior in timber auctions.
• Methodological innovations in auction research include nonparametric tests and realistic modeling.
  • Valuation models are tested to determine whether bidders use independent private values or common values.
  • These insights help in understanding market behavior and informing policy.

Key Information and Policy Implications

• The NBER provides free email services for government data releases, enhancing research accessibility.
• Regulatory reform is a central theme, with ongoing debates about the role of antitrust and regulation in network industries.
• Dynamic efficiency and market design are critical in restructuring and deregulation processes.
• Internet-based services are reshaping pricing strategies, consumer behavior, and market outcomes.
• Auction mechanisms offer important insights into market efficiency, bidding behavior, and policy design.

NBER Structure and Funding

• The NBER is a private, nonprofit research organization founded in 1920.
• Key officers and directors include:
  • President and CEO: Martin Feldstein
  • Board of Directors: Elizabeth E. Bailey, John S. Clarkeson, Robert Mednick, and others.
• The NBER is funded by individuals, corporations, and private foundations to maintain independence and flexibility.
• Working Papers are available at: http://www.nber.org/programs/io/io.html

Conclusion

The NBER Summer 2006 Reporter underscores the importance of economic regulation and antitrust policy in shaping market outcomes and consumer welfare. It highlights ongoing research on oligopoly pricing, auction markets, and industry restructuring, emphasizing the role of the Internet in changing traditional market dynamics. The report also reflects on the complexities of policy design and the need for empirical and theoretical insights to guide regulatory and competitive frameworks.
