The Markov commutator associated to a finite Markov kernel P is the convex semigroup consisting of all Markov kernels commuting with P. Its interest comes from its relation with the hypergroup property and with the notion of Markovian duality by intertwining. In particular, it is shown that the...

We examine the effect of electoral institutions on two important features of representation that are often studied separately: policy responsiveness and the quality of legislators. Theoretically, we show that while a proportional electoral system is better than a majoritarian one at representing...

Pricing decisions are increasingly in the “hands” of artificial algorithms. Scholars and competition authorities have voiced concerns that those algorithms are capable of sustaining collusive outcomes more effectively than human decision makers. If this is so, then our traditional policy tools for...

We develop a model of pork-barrel politics in which a government official tries to improve her reelection chances by spending on targeted interest groups. The spending signals that she shares their concerns. We investigate the effect of such pandering on the public deficit. Pandering widens the...

We develop a growth model in which the use of a non-renewable resource yields waste. Recycling waste produces materials of poor quality. These materials can be reused for production only once a dedicated R&D activity has made their quality reach an exogenous minimum threshold. The economy then...

This paper contributes to the analysis of the impact of socioeconomic factors, like food expenditure level and urbanization, on diet patterns in Vietnam, from 2004 to 2014. Contrary to the existing literature, we focus on the diet balance in terms of macronutrients consumption (protein, fat and...

We study how bundling affects competition between two asymmetric multi-product firms. One firm dominates the other in that it produces better products more efficiently. For low (high) levels of dominance, bundling intensifies (relaxes) price competition and lowers (raises) both firms’ profits. For...

Investment in wind power has grown remarkably in the past decades in Portugal. Although economic development is an argument for investment incentive policies, little evidence exists as to their net impact on local-level unemployment. Using a panel of all 278 Portuguese mainland municipalities for...

Developing countries' incentives to protect intellectual property rights (IPR) are studied in a model of vertical innovation. Enforcing IPR boosts export opportunities to advanced economies but slows down technological transfers and incentives to invest in R&D. Asymmetric protection of IPR,...

Despite the importance of expectiles in fields such as econometrics, risk management, and extreme value theory, expectile regression unfortunately so far remains limited to single-output problems. To improve on this, we define hyperplane-valued multivariate expectiles that show strong advantages...
