Effective regulation versus tacit collusion in the long-distance market: an empirical analysis

Regulatory decisions often must be made in an atmosphere of uncertainty, and arguments presented by the affected parties frequently add to, rather than resolve, that uncertainty. Here, we examine several of the deregulatory decisions affecting the long-distance market that were rendered by the FCC over the two-decade period following the divestiture of AT&T. Our purpose is to provide empirical evidence relevant to some of the arguments regarding market conditions that were presented during that period. Findings suggest that some of the more prominent allegations are not supported by the data.      

Free trade, factor returns, and factor accumulation

A model of development is studied in which physical capital and unskilled labor are good substitutes, and skilled labor is complementary to the resulting aggregate. Growth in a closed economy is compared with two open regimes. Inflows of physical capital only reduce the interest rate and raise both wage rates. The skilled wage rises more sharply, however, increasing the skill premium and accelerating human capital accumulation. Full integration with a larger and more developed neighbor also reduces the interest rate and raises both wage rates, but in this case the skill premium falls and human capital accumulation changes very little.     

Olympic Games: No legacy for sports

Countries whose cities host the Summer Olympic Games increase significantly their success during the competition. We study whether such effect is lasting or not. We compute the effect of hosting on the total number of medals in the subsequent games. To confront the issue that the selection of the host city is endogenous, we use a natural counterfactual: countries whose cities also bid for the Olympics but were not selected by the International Olympic Committee. In all cases, we find that Olympic success on medals fades away immediately after hosting.     

Auditor size, tenure, and bank loan pricing

Using a large sample of U.S. bank loan data from 1996 to 2008, we investigate the relation between two auditor characteristics, namely, auditor size and tenure, and loan interest rates. Our results show the following: First, we find that the loan interest rate is significantly lower for borrowers with prestigious Big 4 auditors than for borrowers with non-Big 4 auditors. Second, we find that auditor tenure is negatively associated with the loan interest rate, suggesting that a long client–auditor relationship lowers the loan borrowing cost. Third, we find that the negative association between auditor size and loan rate is more pronounced for transaction-based term loans than for relationship-based revolving loans. Fourth, our sub-period tests show that our results are driven by the post-Sarbanes–Oxley Act period. Our study provides direct evidence that auditor size and tenure are incremental credit risk-reducing factors in the bank loan market.     

What shapes player performance in soccer? Empirical findings from a panel analysis

In this article, we investigate the pay–performance relationship of soccer players using individual data from eight seasons of the German soccer league Bundesliga. We find a nonlinear pay–performance relationship, indicating that salary does indeed affect individual performance. The results further show that player performance is affected not only by absolute income level but also by relative income position. An additional analysis of the performance impact of team effects provides evidence of a direct impact of team-mate attributes on individual player performance.     

TESTING FOR INVERSE HOMOTHETICITY: A NONPARAMETRIC APPROACH

The efficiency of a decision-making unit can be estimated relative to the direct output possibility set or the indirect (cost-constrained) output possibility set. For the direct and indirect output sets we show that the ratio of two Farrell (radial) efficiency measures equals the ratio of two Zieschang (non-radial) efficiency measures if and only if the production technology is inverse-homothetic. A consequence of inverse homotheticity is that the input and output expansion paths are linear.     

Incomes policy reconsidered

In this study a large data base of individual contract data is used to analyse the impact of wage controls on different groups in the Canadian unionized private sector. Of particular interest is the behavior of the controlled relative to the uncotrolled sector. Statistically significant reductions in wage inflation are discerned both sectors with the effect in the controlled sector being, approximately, twice large as that in the uncontrolled sector.     

Rural-urban migration and urban underemployment in Brazil

Policies to discourage rural-urban migration, in the interest of alleviating urban poverty, are often considered without regard to the migrant experience in cities. This paper examines the income gains associated with rural-urban migration in Brazil and the assimilation of migrants in the urban labor market. Earnings functions, estimated for a sample of individuals from the 1960 population census, are utilized. The analysis shows that migrants have derived significant income benefits from moving, and that within a short period of time, their income and employment pattern are virtually indistinguishable from those of the urban-born.
