Return migration, human capital accumulation and the brain drain

In this paper we present a model that explains migrations as decisions that respond to where human capital can be acquired more efficiently, and where the return to human capital is highest. The basic framework is a dynamic Roy model in which a worker possesses two distinct skills that can be augmented by learning by doing. There are different implicit prices, in different countries and different rates of skill accumulation. Our analysis contributes to the literature on the selection of immigrants and return migrants by offering a richer framework that may help to accommodate selection of emigrants and return migrants that are not immediately compatible with the one-dimensional skill model. Our analysis also has implications for the debate on brain drain and brain gain. In the two skills model presented here, return migration can lead to a mitigation of the brain drain, or even the creation of a “brain gain”, where those who return bring the home country augmented local skills.     

SALARY CAP REGULATION IN PROFESSIONAL TEAM SPORTS

This paper analyzes the effects of a percentage‐of‐revenue salary cap in a team sports league with win‐maximizing clubs and flexible talent supply. It shows that a percentage‐of‐revenue cap produces a more balanced league and decreases aggregate salary payments. Taking into account the idiosyncrasies of European football, our paper further highlights the potential conflicts between the league and society. From the perspective of a league governing body, a percentage‐of‐revenue cap always enhances financial stability of win‐maximizing clubs. A social planner, however, will not permit the introduction of such a cap if fans and players unduly suffer. This paper shows under which conditions the social planner accepts (rejects) a salary cap proposed by the league regulator. (JEL D02, D60, L83)     

Football players’ career and wage profiles

The objective of this article is to look over football players’ career path, from lower leagues to the first league, and the associated wage profile. The information comes from a Portuguese longitudinal matched employer–employee data set defining several career events according to players’ movement across football clubs and across professional and semi-professional leagues. Our identifying strategy relies on coach changes to reduce the potential bias resulting from players’ moves between clubs. The estimated first-difference wage equations indicate that players can expect a wage premium when they get transferred to new clubs in higher leagues or a wage penalty when moving to lower leagues. Players who stay in the same club after the club being relegated can also expect a wage penalty.     

Performance and revenue in professional league football: evidence from Granger causality tests

Using a dataset comprising annual performance (measured by final league position) and gate revenue for 77 Football League clubs which maintained unbroken league membership between 1946 and 1994, the relationship between performance and revenue is investigated using cointegration and causality tests. A cointegrating relationship between performance and revenue is established in only 10 cases out of 77, although it is argued that some caution is required in interpreting these results, due to the low power of the relevant tests in relatively small samples. In Granger causality tests, more evidence is found of causality running from lagged revenue to current performance than of causality in the opposite direction, while the dependence of performance on revenue seems to be greater for the smaller clubs than for the larger. These results lend empirical support to the popular view that, unless checked by mechanisms for revenue redistribution within the league, the natural tendency is for success to become concentrated increasingly among a small group of elite, wealthy clubs.     

OVERINVESTMENT IN TEAM SPORTS LEAGUES: A CONTEST THEORY MODEL

This paper applies contest theory to provide an integrated framework of a team sports league and analyzes the competitive interaction between clubs. We show that dissipation of the league revenue arises from 'overinvestment' in playing talent as a direct consequence of the ruinous competitive interaction between clubs. This overinvestment problem increases if the discriminatory power of the contest function increases, revenue-sharing decreases, and the size of an additional exogenous prize increases. We further show that clubs invest more when they play in an open league compared with a closed league. Moreover, the overinvestment problem within open leagues increases with the revenue differential between leagues.     

REVENUE DIVERGENCE AND COMPETITIVE BALANCE IN A DIVISIONAL SPORTS LEAGUE

The North American model of resource allocation in professional sports leagues is adapted for English (association) football. Comparisons are drawn between the equilibrium allocations of playing talent under objective functions of profit maximisation and win percent maximisation subject to a financial constraint. Empirical revenue functions are reported for 1926–1999. These indicate a shift in the composition of demand favouring big‐city teams and an increase in the sensitivity of revenue to performance. An analysis of match results in the FA Cup suggests an increase in competitive imbalance between teams at different levels of the league's divisional hierarchy, as the theory suggests.     

OWN‐ AND CROSS‐PRICE ELASTICITIES FOR GAMES WITHIN A STATE LOTTERY PORTFOLIO

Lotto demand modeling typically focuses on a single game and evaluates whether estimated “effective price” (expected loss from buying one ticket) elasticity is consistent with net revenue maximization. However, a portfolio of several different lottery games is now usually offered to players and judging the effectiveness of agencies in generating revenue requires estimation of both cross‐price and own‐price elasticities. Here we employ data from Spain to derive elasticities. Results imply that games are under‐priced if net revenue maximization is the goal. But the cross‐price estimates suggest that the operator is successful in limiting the extent to which a large jackpot on one game cannibalizes same‐week sales of other games. The paper also analyzes the impacts from two increases in the level of entry fees introduced during the data period. These appear to have affected net revenue favorably.

Networks and clubs

We formulate a club model where players’ have identical single-peaked preferences over club sizes as a network formation game. For situations with “many” clubs, we provide necessary and sufficient for non-emptiness of the farsighted core and the direct (or myopic) core. With “too few” clubs, if players are farsighted then the farsighted core is empty. In this same case, if players are myopic then the direct core is always nonempty and, for any club network in the direct core, clubs are of nearly equal size (i.e., clubs differ in size by at most one member).     

And if the ball does not cross the line? A comprehensive analysis of football clubs’ performance

The football club market is changing fast in the social media era. In this global market, clubs must maintain or improve fans’ attendance at the stadium; simultaneously, they need, more than ever, to take care of social media. The aim of this article is to test and discuss a comprehensive approach to analysing the performance of football clubs regarding their multiplicity of objectives. We analyse the efficiency of English Premier League (EPL) clubs during three seasons (2012/13–2014/15). The methodologies employed are data envelopment analysis (DEA) and a bootstrapped DEA model. The input is the market value of the squad, and the outputs are sports results, total revenue, the ratio of stadium utilization during the season and an index of social media impact. The results are robust to alternative estimation methods and indicate that EPL clubs still have a margin for improving their overall efficiency, mainly the medium clubs. The analysis of football clubs’ performance with the proposed comprehensive approach provides a useful tool to help managers with evaluation and feedback considering the actual context of the market. The approach brings closer the opportunity to design appropriate strategies to improve clubs’ efficiency as well as competition policies.     

The determinants of NCAA basketball recruiting outcomes

Using recruiting rankings from Rivals.com, the authors examine the determinants of recruiting success among D1 NCAA men’s basketball programmes. After controlling for a host of potentially relevant variables, the authors find that recruiting outcomes are correlated with recent on-court success, historical on-court success, stadium size and playing in a ‘power’ conference. Additionally, teams with a history of sending players to the NBA receive heightened recruiting outcomes. A team with a new coach can expect difficulties with recruiting, while head coaches with national championships receive a recruiting boost. Finally, the authors show that recruiting strategies for guards may differ from recruiting strategies for other players.     

HOW DO HIGH SCHOOL GRADUATES IN JAPAN COMPETE FOR REGULAR,FULL‐TIME JOBS? AN EMPIRICAL ANALYSIS BASED UPON AN INTERNET SURVEY OF THE YOUTH*

We use a survey of Japanese youth within 10 years after high school graduation to investigate impacts of academic and social skills on their success in the job market. We find three major factors account for the job market outcome immediately after school: school characteristics and job‐placement services, academic performance, and social skills, including negative impacts of problematic behaviors at school. Second, when we run a probit regression on whether or not the surveyed individuals hold regular, full‐time jobs, we find the persistent but declining (over age) impact of the job placement immediately after school. Moreover, we find that the impact of variables pertaining to social skills remain significant even after controlling for the job‐placement outcome after school, whereas other variables, such as grade point average or attributes of high schools, are largely irrelevant to the current employment status.     

REVENUE SHARING IN PROFESSIONAL SPORTS LEAGUES

We employ a model of n heterogenous profit-maximizing clubs to analyze the impact of revenue sharing in professional sports leagues on competitive balance. Revenues of each club depend on absolute quality, relative quality and on competitive balance itself so that our model captures much of the preceding literature as special cases. We show that revenue sharing always increases competitive balance if clubs differ only with respect to the impact of absolute quality on revenues. On the contrary, revenue sharing reduces competitive balance if only clubs' relative qualities play a role for revenues or if only two teams are considered.     

A RE-EXAMINATION OF PRODUCTION FUNCTIONS AND EFFICIENCY ESTIMATES FOR THE NATIONAL BASKETBALL ASSOCIATION

This paper seeks to re‐examine the issue of estimating team efficiency for sports teams via an application of data from the National Basketball Association. This paper argues that the inputs the coaches allocate are the players the team employs. Therefore, this paper employs a measure of playing talent in modeling team production. Unlike previous studies, which only employed one measure of playing talent, we employ measures of guards, small forwards and big men in a study of basketball. This paper also argues that the time‐varying stochastic frontier models with the identical temporal pattern assumption such as Lee and Schmidt and Battese and Coelli cannot be used in the analysis of team efficiency in sports. The evidence we present shows by hypothesis test that this argument holds.     

Do Major League Baseball Hitters Engage in Opportunistic Behavior?

This study focuses on 256 Major League Baseball free agent hitters playing under the 2006–2011 collective bargaining agreement to determine whether players engage in opportunistic behavior in their contract year, i.e., the last year of their current guaranteed contracts. Past studies of professional baseball yield conflicting results depending on the econometric technique applied and choice of performance measure. When testing whether players’ offensive performances increase during their contract year, the omitted variable bias associated with OLS and pooled OLS estimation leads to contrary results compared to fixed effects modeling. Fixed effects regression results suggest players increase their offensive performance subject to controlling for the intention to retire.     

ARE COGNITIVE SKILLS RELEVANT IN GENDER EARNINGS DECOMPOSITIONS?

While cognitive skills are known to play an important role in labour market success, empirical evidence is mainly concentrated in its effect on returns to schooling. Evidence on the role of cognitive skills in gender earnings gap decompositions is virtually absent. I use two approaches to investigate the potential for cognitive skills to affect the size and pattern of the unexplained component of the earnings gap (‘relative discrimination’) across the wage distribution, using data from the International Adult Literacy Survey (IALS). It has been shown that when the raw cognitive score is used to control for cognitive skills, the return to schooling cognitive skills is generally underestimated. Once a distinction is made about the origins of cognitive skills (acquired in school versus outside the school), the returns to cognitive skills can vary depending on their origin. I find that using the raw score to control for cognitive skills does not result in any significantly different estimates of the unexplained component of the gap compared to when cognitive skills are not controlled for. However, once cognitive skills by origin of skill are used in place of total cognitive skills, the results change substantially for three of the five countries examined.     

The Impact of Salary Caps in Professional Team Sports

In this paper we analyse the impact of a salary cap on a professional team sports league. We concentrate on the competitive balance, on the level and the distribution of player salaries, on owner profits and total league revenue. A simple model shows that a salary cap can improve the competitive balance among clubs as well as the salary distribution among players. We also investigate how the recent individual salary cap in NBA might affect the competitive balance.     

The framing of product ideas in the making: a case study of the development of an energy saving pump

Research regarding work with ideas in industrial settings has predominantly treated ideas as rather stable ‘black boxes’. This article contributes a new understanding of idea work and seeks to expand our understanding of how a product concept is constituted and synthesised through socio-material interaction of organisational members and engagement in idea work. The article contributes a case study of the development process behind the energy-saving Alpha Pro circulator launched by the Danish pump manufacturer Grundfos. Based on an analysis of how organisational players engage in the controversial and shifting understandings of what seems to constitute a successful product, the article offers a new perspective on navigating the players’ ideas in the political processes of innovation. It suggests that navigation of technological frames can offer a new perspective to make explicit the implicated actors’ world views, including what they perceive as relevant problems and related strategies for solving them.     

Training and worker effort: a signalling perspective

Abstract This paper analyzes the interaction between firms’ investment in general skills training and workers’ incentives. It shows that when a firm has an informational advantage over its workers, its provision of free general skills training can serve as a signal that there will be a long‐term relationship between the firm and its workers. This signal induces the workers to exert more effort in learning firm‐specific skills, which enhances the firm's profits. In contrast with most of the existing literature, the model implies that firms may provide free general skills training even if there is no labour market friction.     

The invariance principle in baseball: new evidence

This article considers the change in revenue sharing in Major League Baseball that occurred prior to the 2007 season and its effects on parity via its effects on marginal revenues. Based on the results from an empirical specification for team revenue, we find evidence that the reduction in revenue sharing increased marginal revenue by more for large market clubs than for small market clubs, despite holding constant other differences in how small and large market club revenues are determined. The upshot of this result is that the modest reduction in revenue sharing could have worsened league parity by 11 to 17 points in winning percentage between small and large market clubs, although other factors affect parity as well. The well-known invariance principle in the economics of sport literature does not appear to hold; however, the current consensus of theoretical models is not confirmed.
