This paper explores the effects that collusion can have in newspaper markets where firms compete for advertising as well as for readership. We compare three modes of competition: i) competition in the advertising and the reader market, ii) semi-collusion over advertising (with competition in the reader market), and iii) (full) collusion in both the advertising and the reader market. We find tha...

Intertemporal movie distribution: Versioning when customers can buy both versions* We study a model of film production, distribution and consumption. The studio can release two goods, a theatrical and a video version, and has to decide on its versioning and sequencing strategy. In contrast with the previous literature, we allow for the possibility that consumers watch both versions. This simple...

ABSTRACT This study examines the informational value of local news outlets and how they affect insider trading. We hypothesize that coverage is a critical channel through which outsiders acquire information, restricts insiders’ ability to profit from their information advantage. argue loss increases opacity faced by outsiders, while making it easier for insiders seize profitable trading opportu...

Media Slant Against Foreign Owners: Downsizing We establish the existence of strong media slant against foreign owners. Using a unique data set from nation-wide distributed quality newspapers in Germany, we find that a foreign firm that downsizes in Germany receives almost twice as much attention than a domestic firm. This quantitative slant is accompanied by qualitative slant; newspapers repor...

We identify a novel channel through which competition among information providers decreases the efficiency of electoral outcomes. The critical insight we put forward is that the level of competition in the market determines the type of information that is provided in equilibrium. In our model, voters can disagree on which issues are important to them (agenda) and on how each issue in their agen...

Measurable variations in (182)W/(183)W, (142)Nd/(144)Nd, (129)Xe/(130)Xe and (136)XePu/(130)Xe in the Earth and meteorites provide a record of accretion and formation of the core, early crust and atmosphere. These variations are due to the decay of the now extinct nuclides (182)Hf, (146)Sm, (129)I and (244)Pu. The (l82)Hf-(182)W system is the best accretion and core-formation chronometer, which...

We analyse a newspaper market where two editors compete for advertising as well as for readership. They first choose the political position of their newspaper, then set cover prices and advertising tariffs. We build on the work of Gabszewicz, Laussel and Sonnac (2001, 2002), whose model we take as the stage game of an infinitely repeated game, and investigate the incentives to collude and the p...

Onze alcalóides acridônicos isolados de Swinglea glutinosa (Bl.) Merr. foram avaliados para suas atividades in vitro contra linhagens de Plasmodium falciparum sensíveis a cloroquina 3D7, Trypanosoma brucei rhodesiense STIB9000 e Leishmania donovani L82. Ensaios com células KB foram também executados com o objetivo de se determinar o grau de toxicidade das substâncias ativas contra os parasitas....
