Objectives Estimate the effects of non-pharmacological interventions used to prevent the spread of COVID-19 on the quality of life, measured by Quality Adjusted Life Years (QALYs). Methods A survey on 1,506 heads of households from Chile in May of 2022. Respondents were asked basic socioeconomic questions and a version of the EQ-5D-5L questionnair...

We model how individual preferences are shaped by strategic reciprocity choices. Our model accounts for heterogeneous players — with intrinsic altruistic, selfish or spiteful preferences —who randomly engage in short-run, as well as long-run, pairwise interactions. To disentangle the strategic component of preferences we allow players to act recipr...

We study global games with strategic substitutes. Specifically, for a class of binary‐action, N‐player games with strategic substitutes, we prove that under payoff asymmetry, as incomplete information vanishes, the global games approach selects a unique equilibrium. We characterize this equilibrium profile; players employ switching strategies at di...

In countries/states where voluntary euthanasia (VE) or physician‐assisted suicide (PAS) is legal, the patient's decision about whether to request VE or PAS heavily relies on the information others provide. We use the tools of microeconomic theory to study how communication between the patient, his family and his physician influences the patient's d...

We propose a game-theoretic model of reciprocity and trust that incorporates personality traits. In the model, positive and negative reciprocity are “reciprocal preferences:” parameters of heterogeneous utility functions that take into account the material welfare of others (positively if they have been kind, negatively if they have been hostile)....

In this paper, we provide a model to study the equilibrium outcome in a market characterized by the competition between two firms offering horizontally differentiated services, in a context where consumers are the basic unit of decision on the demand side and are related through a social network. In the model, we consider that consumers make optima...

This paper analyzes a dynamic strategic model of resource extraction from a global commons. Countries derive benefits from both direct extraction and aggregate conservation of an open access resource. Each period, a country’s output depends both on its resource usage and on the global stock of the resource stored within the ecosystem. Leading examp...

We model dynamic mechanisms for a global commons. Countries value both consumption and conservation of an open access resource. A country's relative value of consumption to conservation is privately observed and evolves stochastically. An optimal quota maximizes world welfare subject to being implementable by Perfect Bayesian equilibria. With compl...

This paper formulates a dynamic model of global carbon consumption in the absence of an effective international agreement. Each period, countries extract carbon from the global ecosystem. A country's output depends both on its carbon usage and on``stored carbon" in the ecosystem. We characterize Business-as-usual (BAU) equilibria as smooth, Markov...

Global games emerged as an approach to equilibrium selection. For a general setting with supermodular payoffs, unique selection of equilibrium has been obtained through iterative elimination of strictly dominated strategies. For the case of global games with strategic substitutes, uniqueness of equilibrium has not been proved by iterative eliminati...

We model dynamic mechanisms for a global commons. Countries benefit from both consumption and aggregate conservation of an open access resource.

An optimal quota maximizes world welfare subject to being imple-mentable by Perfect Bayesian equ...

In this article we present an economic evaluation of policies aimed at increasing deceased organ donation in Chile, a developing country that has low donation rates; it had 5.4 donors per million people (pmp) in 2010. Expert opinions of leading participants in donation and transplantation were analyzed, resulting in a set of local policies aimed at...

This paper studies dynamic mechanisms for a global commons. A leading exam-ple is carbon consumption. We posit a model in which each country benefits both from the use and the aggregate conservation of an open access resource at each date. Conservation is beneficial because it reduces a country's environmental costs of re-source use. A country's re...

Introduction: Kidney allocation should reach a balance between equity and efficiency. In Chile kidneys are allocated based on ABO matching, first to medical priorities and then according to a point scheme considering human leukocyte antigen (HLA) match (60%), waiting list time (20%), and panel-reactive antibodies (PRA; 20%); pediatric recipients r...

Synonyms Learning (and evolution) of social norms, social rules, conventions, customs. Definition Social norms can be understood as standards of behavior that are based on widely shared beliefs of how individual group members ought to behave in a given situation (Horne 2004). The group can be a family, an organization, or a society. Members may fol...

Chile has a low cadaveric organ donation rate; at the same time, living donor transplantation activity is also low. The purpose of this study was to analyze the impact on the number and quality of transplants using various mechanisms for kidney exchange from living donors to patients on Chile's waiting list. A computerized model was developed to si...

In this paper we have estimated the cost savings for the health care system and quality-of-life improvement for patients from an increased number of kidney transplants in Chile. We compared the present value of dialysis and transplantation costs and quality of life over a 20-year horizon. We used Markov models and introduced some degree of uncertai...

In a previous work we studied the equilibrium behavior in a telecommunication market where two interconnected …rms compete, using linear pricing schemes, in the presence of social networks among customers. We showed that social networks matter because equilibrium prices and welfare critically depend on how people are socially related. In this paper...

This paper studies the welfare implications of equilibrium behavior in a market characterized by competition between two interconnected telecommunication ?rms, subject to constraints: the customers belong to a social network. It also shows that social networks matter because equilibrium prices and welfare critically depend on how people are sociall...

In 1979, the "Ley de Aviaciýn Comercial" (Commercial Aviation Act) was passed in Chile. Its main goal was to improve the air transport by means of "Open Sky Policies", competence (freedom of prices) and a progressive lesser intervention of the official authority. Since then an international air policy is applied under the frame of "Open Skyes with...

In this paper we study a static link formation game under consent that has multiple Nash equilibria. In the literature, the use of coalitional refinements has been the standard approach to select among equilibria. Alternatively, based on the Global Games theory, a non cooperative equilibrium selection approach is proposed, so as to select those Nas...

Network formation is frequently modeled using link-formation games and typically present a multiplicity of Nash equilibria. Cooperative refinements - such as strong or coalitional proof Nash equilibria - have been the standard tool used for equilibrium selection in these games. Non-cooperative refinements derived from the theory of global games hav...

In this paper we study the role of resale opportunities in secondary markets over the bidding process in first and second price auctions. This trade opportunity arises owing to the presence of two factors. On the one hand, after receiving the object, the winner obtains new information about the object’s value and on the other hand, the winner may s...

Why does an altruistically inclined player behave altruistically in some contexts and egoistically or spitefully in others? This article provides an economic explanation to this question. The basic argument is centered on the idea that social norms shape our preferences through a process of cultural learning. In particular, we claim that, in contex...

In this paper we present a model where two interconnected network operators compete in linear prices in a market characterized by the existence of social connections among consumers, which are represented by a random regular graph. Assuming horizontal differentiation among operators, the customers select their network provider based on their prefer...

This paper proves an equilibrium selection result for a class of games with strategic substitutes. Specifically, for a general class of binary action, N-player games, we prove that each such game has a unique equilibrium strategy profile. Using a global game approach first introduced by Carlsson and van Damme (1993), recent selection results apply...

Many economic problems with agents interactions have been modeled using network structures or graphs, where agents are represented by nodes and the arcs between nodes represent some speci…c kind of relation between the corresponding agents. In many coordination games with multiple equilibria, the theory of global games have shown that the multiplic...

Using an indirect evolutionary framework we formally examine the evolutionary stability of reciprocal behaviour in the context of a common property resource game. While most previous theoretical research on this topic focuses on the analysis of the evolutionary stability of preferences, in this article we adopt a dierent approach; suggesting that w...

In this paper we study the welfare implications of equilibrium behavior in a market charac- terized by the competition between two interconnected networks, subject to the constraint that customers belong to a social network. We study two dierent regulatory schemes. First, the totally unregulated framework, where interconnection charges and …nal pri...
