Competitive Intensity And Its Two-Sided Effect On The Boundaries Of Firm Performance, Joao Montez, Francisco Ruiz-Aliseda, Michael D. Ryall

Michael D Ryall

The new perspective emerging from strategy's value-capture stream is that the effects of competition are two-fold: competition for an agent bounds its performance from below, while that for its transaction partners bounds from above. Thus, assessing the intensity of competition on either side is essential to understanding firm performance. Yet, the literature provides no formal notion of "competitive intensity" with which to make such assessments. Rather, some authors use added value as their central analytic concept, others the core. Added value is simple, but misses the crucial, for-an-agent side of competition. The core is theoretically complete, but difficult to interpret …

The Integrity Of Financial Analysts: Evidence From Asymmetric Responses To Earnings Surprises, Rui Lu, Wenxuan Hou, Henry Oppenheimer, Ting Zhang

Ting Zhang

This paper investigates the integrity of financial analysts by examining their recommendation responses to large quarterly earnings surprises. Although there is no significant difference in recommendation changes between affiliated and unaffiliated analysts in response to positive earnings surprises, affiliated analysts are more reluctant than unaffiliated analysts to downgrade stock recommendations in response to negative earnings surprises. The evidence implies that conflicts of interest undermine the integrity of financial analysts. We further examine the effects of reputation concern and the Global Research Analyst Settlement as informal and formal mechanisms, on restoring analysts’ integrity. The results show that the positive bias in …

An Analysis Of Risk-Taking Behavior For Public Defined Benefit Pension Plans, Nancy Mohan, Ting Zhang

Ting Zhang

This paper presents the first comprehensive study on the determinants of public pension fund investment risk and reports several new important findings. Unlike private pension plans, public funds undertake more risk if they are underfunded and have lower investment returns in the previous years, consistent with the risk transfer hypothesis. Furthermore, pension funds in states facing fiscal constraints allocate more assets to equity and have higher betas. There also appears to be a herding effect in that CalPERS equity allocation or beta is mimicked by other pension funds. Finally, our results suggest that government accounting standards strongly affect pension fund …

Aggression In Mixed Martial Arts: An Analysis Of The Likelihood Of Winning A Decision, Trevor Collier, Andrew Johnson, John Ruggiero

Trevor Collier

Within the last decade, mixed martial arts has become one of the most popular sports worldwide. The Ultimate Fighting Championship (UFC) is the largest and most successful organization within the industry. In the USA, however, the sport is not sanctioned in all states because some politicians view the sport as too violent. The sport consists of many fighting forms and, unlike boxing, winning a decision requires judging in multiple facets including wrestling, boxing, kickboxing, and jiu-jitsu. In this study, we estimate the likelihood of winning a decision in the UFC. Using data on individual fights, we estimate the probability of …

Measuring Technical Efficiency In Sports, Trevor Collier, Andrew Johnson, John Ruggiero

Trevor Collier

Standard economic production theory is the basis for measuring technical efficiency in sports. Using programming or regression models, efficiency is defined as the distance of a given team observation from the technology. In this article, the authors show that the standard measures of efficiency using deterministic models are biased downward due to serial correlation with respect to the efficiency measure. In particular, if the number of observed wins for a given team is affected by the team’s inefficiency, it is necessarily true that another team is able to produce outside of the technology. As a result, the observed frontier is …

The Impact Of Institutional Arrangements On Educational Efficiency, Trevor Collier

Trevor Collier

Per-pupil expenditures on education in the United States have grown immensely in recent decades, yet student achievement has been stagnant. An abundance of research has sought to solve this enigma, much of it centered on the incentive structure facing administrators. Some recent papers use TIMSS data to analyze the relationship between institutional arrangements—that typically do not vary within a single country—and student achievement. Similarly, we utilize TIMSS 1999 to determine if there is an indirect relationship between institutional arrangements and student achievement, via a relationship with school efficiency. Our results show that the specified link between institutional arrangements and student …

Teacher Qualifications And Student Achievement: A Panel Data Of Analysis, Trevor Collier

Trevor Collier

Recent academic research suggests that teacher quality plays an important role in student achievement: however, empirical research on the efficacy of policies requiring teachers to obtain certain degrees is inconclusive, particularly in elementary education. This paper models a panel data production function with fixed effects using the Early Childhood Longitudinal Study (ECLS-K) to asses the relationship between different undergraduate and graduate majors and elementary student test scores. Specifcally, we aim to discern if there is a difference in teacher efficacy within the different education related majors (e.g. early childhood education and elementary education) and between education and non-education related majors.

Estimation Of Multi-Output Production Functions In Commercial Fisheries, Trevor Collier, Andrew Mamula, John Ruggiero

Trevor Collier

Measuring the productivity of vessels in a multi-species fishery can be problematic. Typical regression techniques are not capable of handling multiple outputs while Data Envelopment Analysis (DEA) tends to ignore the stochastic nature of production. Applied economists have devoted considerable time to this problem and have developed several methods of dealing with the issue of multiple output technologies in commercial fisheries. Our paper contributes to this literature by providing another method for estimating production functions of vessels operating in multi-species fisheries. We utilize a two-stage model – with data from the West Coast Limited Entry Groundfish Trawl Fishery – using …

Tobin, James, Tony Caporale

Tony Caporale

James Tobin was born in Champaign, Illinois, in 1918. He received his bachelor's degree in 1939 and his master's degree in 1940, both from Harvard. Following naval service during the years 1942-6, he returned to his graduate studies and received his PhD from Harvard in 1947. In 1950, he joined the economics department at Yale University, and he has largely remained at Yale and has been identified with this institution throughout his career. He twice directed the Cowles Foundation for Research in Economics, first from 1955 to 1961, and then from 1964 to 1965. He also served for two years, …

The Relationship Between Output Variability And Growth: Evidence From Post War U.K. Data, Tony Caporale, Barbara Mckiernan

Tony Caporale

The paper investigates the relationship between output variability and economic growth using a GARCH-M model with industrial production in post-war Great Britain. The data reveals a positive relationship between variability and growth rates.

Portfolio Evaluation, Downside Risk And An Anomaly, Ladd Kochman

Ladd Kochman

Owing to the developments in portfolio theory in the 1960s, the evaluation of portfolio performance has evolved from a return-only mentality to a process that makes risk no less important than return. Earliest efforts to combine the two dimensions into a single (or composite) measure belong to Treynor (1965) and Sharpe (1966), who suggested dividing a portfolio's return in excess of the risk-free rate by the portfolio's bets and standard deviation, respectively. When Fama (1972) recommended that portfolios pay premiums that capture both market and diversification risk, he was implicitly asking whether Jensen's (1968) use of beta sufficiently measures the …

A Rationale For Meeting Quotas Asymmetrically, J. Patrick Meister, Robert S. Main

Robert S. Main

Under certain conditions, otherwise identical, competing firms may find it jointly preferable to face differing degrees of trade barriers on individual products rather than symmetric trade barriers. The key is the ability to reduce marginal production cost via research and development. The economic significance of this insight is that there could be a role for a market for quota allotments. This insight also has applications to Voluntary Export Restraints in which a priori symmetric, restricted firms may prefer to have individual production levels allocated asymmetrically. This indicates the need for detailed studies of how quotas are met by individual firms. …

Group-Average Observables As Controls For Sorting On Unobservables When Estimating Group Treatment Effects: The Case Of School And Neighborhood Effects, Joseph G. Altonji, Richard K. Mansfield

Rick Mansfield

We consider the classic problem of estimating group treatment effects when individuals sort based on observed and unobserved characteristics. Using a standard choice model, we show that controlling for group averages of observed individual characteristics potentially absorbs all the across-group variation in unobservable individual characteristics. We use this insight to bound the treatment effect variance of school systems and associated neighborhoods for various outcomes. Across four datasets, our conservative estimates indicate that a 90th versus 10th percentile school system increases high school graduation and college enrollment probabilities by at least 0.047 and 0.11. Other applications include measurement of teacher value-added.

Axiomatic Social Choice Theory, David Randall Jenkins

David Randall Jenkins

Ordered Relations Theory’s two axioms ultimately enable (individual: society) well-being transitivity inasmuch as they impound Social Choice Theory’s impossibility theorem, impossibility-resolving axioms, and all such further regressive impossibility theorems and impossibility-resolving axioms.

Polluters’ Profits And Political Response: Direct Control Versus Taxes: Comment, Robert S. Main, Charles W. Baird

Robert S. Main

In a recent issue of this Review, James Buchanan and Gordon Tullock (B-T) presented a public choice analysis of the relative merits of direct controls and taxes in externality control. In Section IV of their paper, B-T consider the case of reciprocal external diseconomies of consumption. They ask whether "... persons in this sort of interaction, acting through the political processes of the community, will impose on themselves either a penalty tax or direct regulation" (p. 143). Their analysis is carried out within the context of a two-person model in which each person consumes the same quantity of a good …

The Relation Between Variance And Information Rents In Auctions, Brett Katzman, Julian Reif, Jesse Schwartz

Jesse A. Schwartz

This paper examines the conventional wisdom, expressed in McAfee and McMillan's (1987) widely cited survey paper on auctions, that links increased variance of bidder values to increased information rent. We find that although the conventional wisdom does indeed hold in their (1986) model of a linear contract auction, this relationship is an artifact of that particular model and cannot be generalized. Using Samuelson's (1987) model, which is similar but allows for unobservable costs, we show that increased variance does not always imply increased information rent. Finally, we give the appropriate measure of dispersion (different from variance) that provides the link …

Collusive Bidding In The Fcc Spectrum Auctions, Peter Cramton, Jesse Schwartz

Jesse A. Schwartz

This paper describes the bid signaling that occurred in many of the FCC spectrum auctions. Bidders in these auctions bid on numerous spectrum licenses simultaneously, with bidding remaining open on all licenses until no bidder is willing to raise the bid on any license. Simultaneous open bidding allows bidders to send messages to their rivals, telling them on which licenses to bid and which to avoid. This “code bidding” occurs when one bidder tags the last few digits of its bid with the market number of a related license. We examine how extensively bidders signaled each other with retaliating bids …

Voice Without Say: Why Capital-Managed Firms Aren’T (Genuinely) Participatory, Justin Schwartz

Justin Schwartz

Why are most capitalist enterprises of any size organized as authoritarian bureaucracies rather than incorporating genuine employee participation that would give the workers real authority? Even firms with employee participation programs leave virtually all decision-making power in the hands of management. The standard answer is that hierarchy is more economically efficient than any sort of genuine participation, so that participatory firms would be less productive and lose out to more traditional competitors. This answer is indefensible. After surveying the history, legal status, and varieties of employee participation, I examine and reject as question-begging the argument that the rarity of genuine …

A Theory Without A Movement, A Hope Without A Name: The Future Of Marxism In A Post-Marxist World, Justin Schwartz

Justin Schwartz

Just as Marx's insights into capitalism have been most strikingly vindicated by the rise of neoliberalism and the near-collapse of the world economy, Marxism as social movement has become bereft of support. Is there any point in people who find Marx's analysis useful in clinging to the term "Marxism" - which Marx himself rejected -- at time when self-identified Marxist organizations and societies have collapsed or renounced the identification, and Marxism own working class constituency rejects the term? I set aside bad reasons to give on "Marxism," such as that the theory is purportedly refuted, that its adoption leads necessarily …

Adverse Selection And Incentives In An Early Retirement Program, Kenneth T. Whelan, Ronald G. Ehrenberg, Kevin F. Hallock, Ronald L. Seeber

Ronald G. Ehrenberg

We evaluate potential determinants of enrollment in an early retirement incentive program for non-tenure-track employees of a large university. Using administrative record on the eligible population of employees not covered by collective bargaining agreements, historical employee count and layoff data by budget units, and public information on unit budgets, we find dips in per-employee finance in a budget unit during the application year and higher recent per employee layoffs were associated with increased probabilities of eligible employee program enrollment. Our results also suggest, on average, that employees whose salaries are lower than we would predict given their personal characteristics and …

Economic And Statistical Analysis Of Discrimination In Hiring, Ronald G. Ehrenberg, Robert Smith

Ronald G. Ehrenberg

Legal and administrative determinations of employers' compliance with "equal employment opportunity" (EEO) requirements often hinge on the Issue of the availability of protected class members to employers. That is, courts and affirmative action review agencies compare the hire rates of protected class members (the ratio of the number of protected class members hired to the number who applied or who were potentially available) to the comparable ratio for other applicants, in assessing whether an employer's hiring policies meet the standards required of them by equal opportunity regulations. The purpose of this paper is to review what economic theory suggests affects …

An Economic Analysis Of The Market For Law School Students, Ronald G. Ehrenberg

Ronald G. Ehrenberg

This study utilizes data from a number of sources to estimate how lawyers' starting salaries relate to their ability, the quality of law school they attended, and whether the law school was a private institution. Based upon this analysis, a benefit—cost analysis is conducted of the value of attending a high-quality private institution. Analyses are also done of how the financial attractiveness of law vis-a-vis other careers has changed in recent years and a conceptual framework discussed for law schools to use in allocating their financial aid resources.

Neoliberalism And The Law: How Historical Materialism Can Illuminate Recent Governmental And Judicial Decision Making, Justin Schwartz

Justin Schwartz

Neoliberalism can be understood as the deregulation of the economy from political control by deliberate action or inaction of the state. As such it is both constituted by the law and deeply affects it. I show how the methods of historical materialism can illuminate this phenomenon in all three branches of the the U.S. government. Considering the example the global financial crisis of 2007-08 that began with the housing bubble developing from trade in unregulated and overvalued mortgage backed securities, I show how the repeal of the Glass-Steagall Act, which established a firewall between commercial and investment banking, allowed this …

Reaching For The Brass Ring: The U.S. News & World Report Rankings And Competition, Ronald Ehrenberg

Ronald G. Ehrenberg

[Excerpt] The behavior of academic institutions, including the extent to which they collaborate on academic and nonacademic matters, is shaped by many factors. This paper focuses on one of these factors, the U.S. News & World Report (USNWR) annual ranking of the nation’s colleges and universities as undergraduate institutions, exploring how this ranking exacerbates the competitiveness among American higher education institutions. After presenting some evidence on the importance of the USNWR rankings to both public and private institutions at all levels along the selectivity spectrum, I describe how the rankings actually are calculated, then discuss how academic institutions alter their …

Crafting A Class: The Trade-Off Between Merit Scholarships And Enrolling Lower-Income Students, Ronald G. Ehrenberg, Liang Zhang, Jared M. Levin

Ronald G. Ehrenberg

[Excerpt] It is well known that test scores are correlated with students’ socio-economic backgrounds. Hence, to the extent that colleges are successful in “buying” higher test-score students, one should expect that their enrollment of students from families in the lower tails of the family income distribution should decline. However, somewhat surprisingly, there have been no efforts to test if this is occurring. Our paper presents such a test. While institutional-level data on the dollar amounts of merit scholarships offered by colleges and universities are not available, data are available on the number of National Merit Scholarship (NMS) winners attending an …

The 1995 Nrc Ratings Of Doctoral Programs: A Hedonic Model, Ronald Ehrenberg, Peter Hurst

Ronald G. Ehrenberg

We describe how one can use multivariate regression models and data collected by the National Research Council as part of its recent ranking of doctoral programs (Research-Doctorate Programs in the United States: Continuity and Change) to analyze how measures of program size, faculty seniority, faculty research productivity, and faculty productivity in producing doctoral degrees influence subjective ratings of doctoral programs in 35 academic fields. Using data for one of the fields, economics, we illustrate how university administrators can use the models to compute the impact of changing the number of faculty positions they allocate to the field on …

The Impact Of U.S. News & World Report College Rankings On Admissions Outcomes And Pricing Policies At Selective Private Institutions, James Monks, Ronald G. Ehrenberg

Ronald G. Ehrenberg

Despite the widespread popularity of the U.S. News & World Report College rankings there has been no empirical analysis of the impact of these rankings on applications, admissions, and enrollment decisions, as well as on institutions' pricing policies. Our analyses indicate that a less favorable rank leads an institution to accept a greater percentage of its applicants, a smaller percentage of its admitted applicants matriculate, and the resulting entering class is of lower quality, as measured by its average SAT scores. While tuition levels are not responsive to less favorable rankings, institutions offer less visible price discounts in the form …

Faculty Turnover At American Colleges And Universities: Analyses Of Aaup Data, Ronald G. Ehrenberg, Hirschel Kasper, Daniel Rees

Ronald G. Ehrenberg

This paper uses institutional level data collected by the American Association of University Professors as part of their annual survey of faculty members' compensation to analyze faculty turnover. Analyses of aggregate data over almost a twenty-year period highlight how remarkably stable faculty retention rates have been nationwide and how little they vary across broad categories of institutions. Analyses of variations in faculty retention rates across individual institutions stress the role that faculty compensation levels play. Higher levels of compensation appear to increase retention rates for assistant and associate professors (but not for full professors) and the magnitude of this effect …
