Consumer surplus and the reform of network industries: a primer

Starting from an industry where production is provided by a public monopolist, we observe the effects of a sequence of reforms within the network industry on consumer surplus. Using a simple comparative statics framework, we find the indifference conditions for the consumer surplus under the following regimes: a public monopoly, an unregulated private monopoly, a regulated private monopoly, a vertically disintegrated monopoly, a duopoly and a liberalized market. The results are determined by the relative size of the x-inefficiencies of the public monopolist, allocative inefficiencies of the private monopoly, the cost of unbundling and the costs related to establishing a competitive market.     

The evolution of conventions in minimum effort games

The literature on minimum effort game has been concerned with a symmetric game with linear payoff functions. The main aim of the present paper is to study the coordination problem arising in a not necessarily symmetric minimum effort game with two players. The sources of asymmetry can be twofold: the productivity of effort and the distribution of the join output. To select among the Pareto ranked equilibria we use the stochastic stability criterion. We show that, for any configuration parameters, the set of stochastically stable equilibria coincides with the set of potential maximizers. We also show that when the disutility of effort is linear, the Pareto dominant equilibrium is stochastically stable provided that the distributive parameter belongs to a well defined range. When the disutility of effort is nonlinear no distributive arguments can be used to successfully affect the selection process. Lastly we prove that the connection between stochastic stability and maximum potential can fail when more than two agents are considered.     

How do corporate websites contribute to the information environment? Evidence from the U.S. and Taiwan

We study corporate website disclosures in the U.S. and Taiwan, two countries with different regulatory and market environments, to provide insights into the uniformity of website content and its contribution to the information environment. We observe significant variation in content both within and between the two countries. U.S. firms with higher analyst following tend to create more transparent financial information environments and provide disclosures that are complementary to analysts’ analyses through their corporate websites. They also tend to provide easier access to investor relations (IR) services if analyst coverage is light or nonexistent. However, neither effect is true in Taiwan where the securities analysis industry is less mature. Individual investors have greater ownership share in U.S. firms with more information about IR services on their websites; however, their ownership share drops as financial disclosure on the firm’s website increases, consistent with institutions diluting individual ownership in firms with more transparency in financial reporting. In Taiwan, however, institutions dilute individual ownership share in firms with less financial information and more trading information on their websites. These results are consistent with Barber et al.’s (2009) findings that institutions find Taiwan firms that attract the aggressive, speculative trading of individuals to be extremely profitable investments. Website disclosures in both countries have some effect on the stock-price response to mandatory earnings releases, but their impact is greater in the U.S. Our findings indicate that website disclosures contribute to the information environment and are related to the degree of interest in the firm by sophisticated market participants. Thus, they provide insights to regulators of both countries as they seek to improve disclosure and “level the information playing field.”     

Is sustainable tourism an obstacle to the economic performance of the tourism industry? Evidence from an international empirical study

Sustainability has become an important strategic objective for tourism destinations worldwide. All analytical tourism competitiveness models make direct or indirect positive references to sustainability. It is accepted that sustainable tourism can reduce resource costs and help create market differentiation. Nevertheless, it has traditionally been considered that, short term, sustainability measures can reduce profitability and compromise competitiveness. Debates on the progress, implications, and practicality of sustainable tourism remain open. The relationship between economic sustainability, and environmental and sociocultural sustainability, is a central but largely unresearched area for tourism scholars, especially at the macro level. This study explores that difficult but essential area, using the World Economic Forum's empirical evidence from 128 countries, backed by the economic data search tool of the World Travel & Tourism Council. It demonstrates that progress in tourism sustainability does not affect a country's main economic tourism indicators in the short term, and does not constrain profitability and competitiveness. It also finds that sustainable tourism is not a luxury that only rich countries can afford, nor should it prevent development and perpetuate poverty in developing countries. An effective marketing and communication program about sustainable tourism is, however, found to be essential for economic success.     

Carrot and yardstick regulation: Enhancing market performance with output prizes

The fundamental objective of most regulatory mechanisms is to expand output at a sufficiently low cost to consumers. Many useable mechanisms, such as Loeb and Magat's, require detailed demand information and substantial profit recapture by the regulator in order to achieve this objective. We present an apparently unexplored alternative approach-inducing competition among firms for shares of a monetary reward. Payments to a firm for output expansion thus depend on both its own behavior and the actions of other firms, which can even be firms in unrelated industries. We show that in a wide variety of circumstances, the resultant increase in consumer surplus exceeds the reward. Hence, even with no profit recapture, our approach can lead to Pareto improvements.     

The Information in Management's Expected Earnings Report Date: A Day Late, a Penny Short

Since 1995, managers of thousands of firms have voluntarily disclosed the expected date of their firm's next quarterly earnings announcement to Thomson Financial Services Inc. These disclosures are approximately 500% more accurate than the simple time–series expected report dates used in prior accounting research. These disclosures are also informative. On average, managers who miss their own expected date eventually report earnings that fall about one penny per share below consensus forecasts for each day of delay. Investors respond by sending the price of late–announcing stocks down at the missed expected report date and continue to send them down as the reporting delay lengthens, consistent with our "day late, penny short" result. Despite this, we find that the market response at the time earnings are announced still depends on whether the announcement is early, on time, or late relative to the firm's own expected report date.     

Voluntary Assurance of Voluntary CSR Disclosure

We study a firm's decisions to engage in socially responsible activities, voluntarily report on them, and purchase external assurance of the report. In our signaling model, neither firm type nor the level of activity is observed. We show that if voluntary assurance is not too expensive, the firm that engages in more socially responsible activities purchases external assurance and thus “selects” a separating equilibrium. As a result, CSR reports can be used to infer the level of activity and this causes all firms to engage in more socially responsible activity. Further, when voluntary assurance is required to support a separating equilibrium, greater monitoring by social activists increases the chosen quality of voluntary assurance—voluntary assurance and monitoring by social activists are complements, not substitutes.     

The effectiveness of movie trailer advertising

Prior to a movie release in theaters, trailer advertising provides valuable information that can help viewers and investors form expectations about the movie's future success. While previous research has looked at the financial implications of movie advertising budgets, the effects of trailers' creative characteristics on abnormal returns have not yet been investigated. Using a sample of movie trailers, results from our event study and cross-sectional analysis show that the appeal of the movie plot revealed in the trailer, the number of scene cuts and the inclusion of violent, sexual, or humorous scenes influence the movie's abnormal returns. However, the use of special effects in the movie trailer does not impact investors. Results also suggest that investors react more strongly to first than to follow-up trailers released for the movie, and that early release of the first positively impacts the movie's returns.     

Egalitarianism: An evolutionary perspective

Two parties bargain over a pie, the size of which is determined by their previous investment decisions. Investment costs are heterogenoeus. The bargaining rule is sensitive to investment behavior. Our main result is that egalitarianism is more likely to emerge in situations in which private property over the fruits of one's own independent investment is not secured.     

Log-concave probability and its applications

Summary. In many applications, assumptions about the log-concavity of a probability distribution allow just enough special structure to yield a workable theory. This paper catalogs a series of theorems relating log-concavity and/or log-convexity of probability density functions, distribution functions, reliability functions, and their integrals. We list a large number of commonly-used probability distributions and report the log-concavity or log-convexity of their density functions and their integrals. We also discuss a variety of applications of log-concavity that have appeared in the literature.Received: 31 December 2003, Revised: 22 March 2004, JEL Classification Numbers: C40, D40, D80.
