Do investors trade uniformly through time?

This study tests whether investors trade uniformly through time by analyzing the quarter-by-quarter trading decision of individual shareholders in one no-load mutual fund family over nearly six years. These shareholders' trading probabilities change dramatically through time. Time has a larger economic effect on the shareholders' trading decisions than data commonly used in prior research, including fund performance. This effect is larger among shareholders who have more prior transactions, and it is robust to controls for unobserved heterogeneity.     

Team promotion in early major league baseball and the origin of the closed sports league

I argue that a quasi team-promotion system similar to European professional sports leagues once existed in the US, contrary to common perceptions. The first American pro team sport was baseball. From the creation of the first major league in 1876 to the early 1890s, entry was common, occurring primarily by the “promotion” of clubs in operation the previous season. The informal system ended abruptly after an 1892 merger that formed the prototype closed monopoly sports league. Empirical analysis indicates that the cessation of entry reduced competitive balance, and that in their initial year promoted teams outperformed new start-ups. While historians have recognized the elimination of between-league competition as an underlying motive for the monopoly merger, the simultaneous elimination of club entry and competition for league membership has gone virtually unnoticed.     

Ethical decision making: A review of the empirical literature

The authors review the empirical literature in order to assess which variables are postulated as influencing ethical beliefs and decision making. The variables are divided into those unique to the individual decision maker and those considered situational in nature. Variables related to an individual decision maker examined in this review are nationality, religion, sex, age, education, employment, and personality. Situation specific variables examined in this review are referent groups, rewards and sanctions, codes of conduct, type of ethical conflict, organization effects, industry, and business competitiveness. The review identifies the variables that have been empirically tested in an effort to uncover what is known and what we need to know about the variables that are hypothesized as determinants of ethical decision behavior.Robert C.

Necessary and Sufficient Conditions for Existence and Uniqueness of Recursive Utilities

We obtain exact necessary and sufficient conditions for existence and uniqueness of solutions of a class of homothetic recursive utility models postulated by Epstein and Zin. The conditions center on a single test value with a natural economic interpretation. The test sheds light on the relationship between valuation of cash flows, impatience, risk adjustment, and intertemporal substitution of consumption. We propose two methods to compute the test value when an analytical solution is not available. We further provide several applications.     

Retail price concentration, transaction costs, and price flexibility circa 1900

This paper studies a unique 1901 data set containing prices of three products obtained from grocery stores in over 1400 cities nationwide. A striking characteristic is a high concentration of retail prices at relatively few “even” numbers. I propose a novel transactions cost explanation for this phenomenon on which existing theory is silent. In particular, grocers selected prices that simplified the task of toting up customer bills by hand and reduced related costs. As stores independently adopted this strategy across the country, prices converged to a few even numbers. Several empirical regularities for all three products are consistent with this explanation. An important implication is that preferences for computationally convenient prices would have made prices “sticky.” An independent study of price flexibility circa 1890 supports this hypothesis. The underlying data show price concentration patterns similar to the 1901 data, suggesting that the phenomenon covered a wide range of products.     

The NCAA Cartel and Competitive Balance in College Football

The NCAA regulates college football player recruiting, eligibility, and compensation. The economic theory of cartels suggests that one consequence may be reduced competitive balance. The enforced restrictions inhibit weak teams from improving, and protect strong teams from competition. A stratification is implied which should be evident over time as less churning in national rankings and conference standings, and fewer schools achieving national prominence. I test this general hypothesis by comparing various competitive balance measures for about 25 years before and after NCAA enforcement began in 1952. The hypothesis is supported by all measures at both the national and conference levels.     

Sabotage in rent-seeking contests

This article considers the interaction between two types ofeffort in lobbying contests: effort that improves the contestant'sown performance (standard rent seeking), and effort that reducesparticular rivals' performance (sabotage). Due to a positiveexternality, sabotage is a 'small number' phenomenon. Sabotagemay increase lobbying efforts and the dissipation rate in lobbyingcontests compared to a situation in which sabotage is not feasible.     

Telecommunications Services in Canada: The Changing Policy and Regulatory Context

This study assesses the changing policy and regulatory context for telecommunications services and their provision and use in Canada. A number of recent developments, including a I987 Department of Communications policy statement, recent CRTC regulatory decisions, changes in the role of Telesat Canada and Teleglobe Canada, as well as implementation of the Canada-US FXA, are treated. Prospective developments in several other areas such as another attempt to introduce longdistance competition in Canada and the implications of the Uruguay Round services trade negotiations are also examined. The theme throughout is that telecommunications services, both domestic and international, are being provided and used within an increasingly open and competitive environment.
