We investigate the welfare effects of vertical integration of regional sports networks (RSNs) with programming distributors in U.S. multichannel television markets. Vertical integration can enhance efficiency by reducing double marginalization and increasing carriage of channels, but can also harm welfare due to foreclosure and raising rivals' costs incentives. We estimate a structural model of viewership, subscription, distributor pricing, and affiliate fee bargaining using a rich dataset on the U.S. cable and satellite television industry (2000-2010). We use these estimates to analyze the impact of simulated vertical mergers and de-mergers of RSNs on competition and welfare, and examine the efficacy of regulatory policies introduced by the U.S. Federal Communications Commission to address competition concerns in this industry.

Conceptual priming has become an increasingly popular tool in economics. Here, we review the literature that uses priming in incentivized experiments to study economic questions. We mainly focus on the role of social identity, culture, and norms in shaping preferences and behavior. We also discuss recently raised objections to priming research and conclude with promising avenues for future research.

In many multiple testing problems, the individual null hypotheses (i) concern univariate parameters and (ii) are one-sided. In such problems, power gains can be obtained for bootstrap multiple testing procedures in scenarios where some of the parameters are 'deep in the null' by making certain adjustments to the null distribution under which to resample. In this paper, we compare a Bonferroni adjustment that is based on finite-sample considerations with certain 'asymptotic' adjustments previously suggested in the literature.

We study the differential impact of large exchange rate devaluations on the cost of living at different points on the income distribution. Across product categories, the poor have relatively high expenditure shares in tradeable products. Within tradeable product categories, the poor consume lower-priced varieties. Changes in the relative price of tradeables and the relative prices of lower-priced varieties following a devaluation will affect the cost of the consumption basket of the low-income households relative that of the high-income households. We quantify these effects following the 1994 Mexican peso devaluation and show that their distributional consequences can be large. In the two years that follow the devaluation, the cost of the consumption basket of those in the bottom decile of the income distribution rose between 1.46 and 1.6 times more than the cost of the consumption basket for the top income decile.

Le document met la discussion des réserves transférables en relation avec l'exigence politique que les réserves légales minimales soient fixées par canton. A ce propos, il montre l'évolution de la régulation des réserves des 13 dernières années et met en évidence l'augmentation du risque qui y est lié et que l'OFSP a pris en compte de manière quelque peu négligente. Ce document prouve aussi pourquoi l'exigence de réserves cantonales est en contradiction la plus fondamentale avec l'actuariat, base des affaires d'assurance. La discussion des avantages et des inconvénients des réserves transférables fait ressortir que celles-ci posent également de nombreuses questions et troubleraient encore davantage le marché déjà fortement ébranlé. Mais afin de satisfaire tout de même au mandat du conseil d'administration, un modèle de transférabilité interne à la caisse est développé à l'alinéa 4.2.6. et une autre idée est esquissée à l'alinéa 5. Tous deux pourraient contribuer à désamorcer la discussion en matière de réserves cantonales.

We study the effects of the adoption of new agricultural technologies on structural transformation. To guide empirical work, we present a simple model where the effect of agricultural productivity on industrial development depends on the factor bias of technical change. We test the predictions of the model by studying the introduction of genetically engineered soybean seeds in Brazil, which had heterogeneous effects on agricultural productivity across areas with different soil and weather characteristics. We find that technical change in soy production was strongly labor saving and led to industrial growth, as predicted by the model.

This paper studies the optimal design of dynamic research contests. We introduce interim transfers, which are paid in every period while the contest is ongoing, to an otherwise standard setting. We show that a contest where: (i) the principal can stop the contest in any period, (ii) a constant interim transfer is paid to agents in each period while the contest is ongoing, and (iii) a final prize is paid once the principal stops the contest, is optimal for the principal and implements the first-best.

This paper provides new evidence on gender bias in teaching evaluations. We exploit a quasi-experimental dataset of 19,952 student evaluations of university faculty in a context where students are randomly allocated to female or male instructors. Despite the fact that neither students' grades nor self-study hours are affected by the instructor's gender, we find that women receive systematically lower teaching evaluations than their male colleagues. This bias is driven by male students' evaluations, is larger for mathematical courses and particularly pronounced for junior women. The gender bias in teaching evaluations we document may have direct as well as indirect effects on the career progression of women by affecting junior women's confidence and through the reallocation of instructor resources away from research and towards teaching.
