Auctioning the Airwaves: The Contest for Broadband pcs Spectrum

The House and Senate of the United States Congress recently passed legislation that directs the FCC to establish a system for using auctions to allocate the use of radio spectrum for personal communications services. There is a unique and unprecedented set of issues that arise in this context, which are of interest to economists, industry analysts, regulators, and policymakers. We discuss these issues and evaluate their likely impact on the outcome of the spectrum auctions. In addition, we argue that there may be pitfalls in the auction procedure adopted by the FCC, and we discuss possible alternative procedures.     

Cost monotonicity, consistency and minimum cost spanning tree games

We propose a new cost allocation rule for minimum cost spanning tree games. The new rule is a core selection and also satisfies cost monotonicity. We also give characterisation theorems for the new rule as well as the much-studied Bird allocation. We show that the principal difference between these two rules is in terms of their consistency properties.     

A characterization of egalitarian equivalence

Summary Consider a solution (an allocation rule) for an economy which satisfies the following criteria: (1) Pareto efficiency, (2) monotonicity, in the sense that if the set of attainable allocations of the economy becomes larger then the solution makes no consumer worse-off, (3) a weak and primitive notion of fairness with respect to some commodity, say commodityh, in the sense that in an exchange economy in which the aggregate endowment consists only of commodityh, the solution is equal division. We show that in the class of economies which includes non-convex technologies the only such solution is egalitarian equivalence with respect to commodityh. It is also shown that this characterization of egalitarian equivalence holds in convex exchange economies if we add a weak version of a positive association requirement.We are grateful to William Thomson and three anonymous referees for extensive comments on an earlier version. We also acknowledge helpful comments of the participants of the Social Choice and Welfare Conference held in Caen, June 1992.     

Farsighted network formation

This paper studies a model of dynamic network formation when individuals are farsighted: players evaluate the desirability of a “current” move in terms of its consequences on the entire discounted stream of payoffs. We define a concept of equilibrium which takes into account farsighted behavior of agents and allows for limited cooperation amongst agents. We show that an equilibrium process of network formation exists. We also show that there are valuation structures in which no equilibrium strategy profile can sustain efficient networks. We then provide sufficient conditions under which the equilibrium process will yield efficient outcomes.     

On Endogenously Staggered Prices

Taylor's model of staggered contracts is an influential explanation for nominal inertia and the persistent real effects of nominal shocks. However, in standard imperfect competition models, if agents are allowed to choose the timing of pricing decisions, they will typically choose to synchronize. This paper provides a simple model of imperfect competition which produces stable staggering. Our argument relies on strategic interaction at two levels—between firms within an industries, and across industries—and produces a continuum of staggered price equilibria. These equilibria are strict, and hence stable under a simple adaptive learning process.     

Stock exchange governance initiatives: Evidence from the Italian STARs

Can a stock exchange improve corporate governance and transparency by designating companies that exhibit superior corporate governance? In 2000, the Borsa Italiana created a mid-cap segment with strong listing standards, which is composed of firms (called STARS) that follow stricter standards of transparency, disclosure, monitoring and liquidity. We find that STAR firms exhibit governance characteristics not observed in non-STAR firms, such as a higher incidence of audit and executive committees and higher debt ratios. They experienced a modestly favorable share price response upon the implementation of the STAR initiative. Moreover, they experienced significantly higher buy and hold returns and transparency after the initiative. Several governance characteristics are cross-sectionally associated with performance following the STAR initiative. Overall, the results suggest that firms may be willing to improve governance when they are endorsed by a credible agency for doing so, and such improvements may lead to better performance. The STAR initiative may serve as a model that can be adapted by other stock exchanges to promote transparency and governance.     

On the Choice of Superannuation Funds in Australia

Using a sample of Australian retail and wholesale superannuation funds to proxy for choice and limited choice alternatives, respectively, we investigate the costs and benefits of providing choice to investors. We find that investors who have choice don't respond to fees. Also, loads - typical of the choice environment - are likely to be a dead-weight loss borne by investors. Employees who involuntarily contribute to (employer) funds, tend to pay the lowest fees. Given these results, the advantages of choice become questionable. Our results show that managers of limited choice funds achieve greater positive abnormal returns than retail fund managers. The analysis of flows provides insight into why choice funds do not perform better than limited choice funds. Investors are not responding to historical performance as predicted.     

Occupational status,earnings, and fertility expectations: Development and estimation of a causal model

Summary This paper tests, within the framework of LISREL, the causal structures of occupational status, earnings, and fertility expectations using data from the 1984 Canadian Fertility Survey of currently married and common-law women aged 18–44. Differential occupational status, earnings, and fertility among three groups of wives classified by generation of Canadian residence are also examined. The models incorporate age, education, work experience, and ethnic/English language ability as exogenous determinants of occupational status, earnings, and fertility.The major findings are: (1) lower earnings of third generation wives are strongly related to lower levels of education, work experience, and job status; (2) wives who speak an ethnic language are likely to have lower fertility than comparable wives who do not speak an ethnic language; and (3) generational effects on earnings and fertility are limited to differences in education, work experience, and occupational status.The author is grateful to Dr. Karol J. Krotki, co-director of the Canadian Fertility Study, for permission to analyze the Canadian Fertility Survey data. Special thanks are also due to Ms. Margaret King for her comments on an earlier draft of the paper.
