Do Entry Conditions Vary over Time? Entry and Competition in the Broadband Market: 1999-2003
We extend Bresnahan and Reiss’s (1991) model of local oligopoly to allow firm entry and exit over time. In our framework, entrants have to incur sunk costs in order to enter a market. After becoming incumbents, they disregard these entry costs in deciding whether to continue operating or to exit. We apply this framework to study market structure and competitive conduct in local markets for high-speed Internet service from 1999 to 2003. Replication of Bresnahan and Reiss’s framework generates unreasonable variation in firms’ competitive conduct over time. This variation disappears when entry costs are allowed. We find that once the market has one to three firms, the next entrant has little effect on competitive conduct. We also find that entry costs vary with the order of entry, especially for early entrants. Our findings highlight the importance of sunk costs in determining entry conditions and inferences about firm conduct.entry; exit; oligopoly; broadband; high-speed internet; competition; pricing
Does the Fourth Entrant Make Any Difference? Entry and Competition in the Early U.S. Broadband Market
We study the importance of sunk costs in determining entry conditions and inferences about firm conduct in an adapted Bresnahan and Reiss (1991, 1994) framework. In our framework, entrants incur sunk costs to enter, while incumbents disregard these costs in deciding on continuation or exit. We apply this framework to study entry and competition in the local U.S. broadband markets from 1999 to 2003. Ignoring sunk costs generates unreasonable variation in firms’ competitive conduct over time. This variation disappears when entry costs are allowed. Once the market has one to three incumbent firms, the fourth entrant has little effect on competitive conduct.entry; market structure; Sunk Costs; Broadband Market
The Impact of Regulations on the Supply and Quality of Care in Child Care Markets
We examine the impact of state child care regulations on the supply and quality of care in child care markets. We exploit panel data on both individual establishments and local markets to control for state, time, and, where possible, establishment-specific fixed effects to mitigate the potential bias due to policy endogeneity. We find that the imposition of regulations reduces the number of center-based child care establishments, especially in lower income markets. However, such regulations increase the quality of services provided, especially in higher income areas. Thus, there are winners and losers from the regulation of child care services.
Strategic Information Disclosure: The Case of Multi-Attribute Products with Heterogeneous Consumers
We examine the incentives for firms to voluntarily disclose otherwise private information about the quality attributes of their products. In particular, we focus on the case of differentiated products with multiple attributes and heterogeneous consumers. We show that there exist certain configurations of consumers’ multi-dimensional preferences under which a firm, no matter whether producing a high- or low-quality product, may choose not to reveal the quality even with zero disclosure costs. The failure of information unraveling arises when providing consumers with more information results in more elastic demand, which triggers more intensive price competition and leads to lower prices and profits for competing firms. As a result, the equilibrium in which disclosure is voluntary may diverge from that in which disclosure is mandatory.
