When exogenously imposed, rank-order tournaments have incentive properties but their overall efficiency is reduced by a high variance in performance (Bull, Schotter, and Weigelt 1987). However, since the efficiency of performance-related pay is attributable both to its incentive effect and to...

The literature has shown that the overall efficiency of exogenously imposed tournaments is reduced by a high variance in performance. This paper reports results from an experiment analyzing whether allowing subjects to self-select into different payment schemes is reducing the variability of...

This paper models the competition of user networks as a continuous-time Markov process. It presents a dynamic version of the Discrete Choice Analysis with state-dependent choice probabilities. Among other things, we show that the network competition can be characterized by the coexistence of...

We develop models of markets with procrastinating consumers where competition operates - or is supposed to operate - both through the initial selection of providers and through the possibility of switching providers. As in other work, consumers fail to switch to better options after signing up...

When firms' shrouding of charges, as in Gabaix and Laibson (2006), meets with consumers' salient thinking, as in Bordalo et al. (2013), this can have severe welfare implications. The ensuing excessive competition for headline prices tends to inefficiently bias consumers' choice towards...

When preferences are sensitive to context, firms may try to influence purchase decisions by designing the environment of consumption choices. Confirming anecdotal evidence on retailer marketing tricks, we show that competitive retailers exploit context-sensitivity by designing environments that...

Portuguese Abstract: Exploramos vários jogos diferenciais para simular a competição entre duas firmas em Preço, Publicidade, e Preço e Publicidade simultâneamente. Os resultados reforçam conclusões importantes na literatura e complementam-na, permitindo analisar a competição em dois...

This is a ready-to-read version of my previous paper ‘Deciphering the Two-Sided Market Model of Rochet and Tirole’. It blows away the smokescreen of logical disorder, incoherent language and mathematical sophistication of the original article by rephrasing the model in clear language,...
