The present study addresses the construction of the altruistic rhetoric as a necessary condition for the viability of business models built on egg donation. Through 14 semi-structured interviews carried out with staff of fertility clinics that offer treatments with oocyte donation, this research analyses the factors operating in the process of commercialization of the donor's body, regarding the maintenance of both the legitimacy of the system and the flow of donors willing to fulfil their productive role. In short, this study enables a better understanding of the role of professionals in...

Padilla Medina, MD & Degli Esposti, S. (2021) Mecanismos para impulsar la comunicación científica. Instituto de Políticas y Bienes Públicos (IPP) CSIC, Working Paper. 2021-02

Mª Dolores Padilla Medina y Sara Degli Esposti

Este trabajo pretende detectar los factores clave a la hora de incentivar la comunicación de la ciencia por la comunidad científica. Se parte de una serie de datos recogidos a través de encuesta a científicos en España, Holanda, Austria y otros países por el proyecto europeo de investigación H2020 TRESCA (Trustworthy, Reliable and Engaging Scientific Communication Approaches). Los datos se analizan para comprender cómo se da esa comunicación actualmente. Encontramos que existen diferencias entre aquellos incentivos para la comunicación entre pares y la comunicación con el público general....

Holl, A., y Rama, R. (2021). Las PYMES de Madrid: Grado de innovación y percepción empresarial del potencial de los Organismos Públicos de Investigación. Instituto de Políticas y Bienes Públicos (IPP) CSIC, Working Paper. 2021-01

Adelheid Holl y Ruth Rama

Resumen: En este trabajo se examina el panorama de la innovación en las PYMES, con especial énfasis en aquellas que operan en las cuatro Áreas de la estrategia RIS 3 de la Comunidad de Madrid. El propósito consiste en analizar las posibilidades de transferencias de conocimiento y cooperación de dichas empresas con los Organismos Públicos de Investigación (OPIS). Basándonos en datos de la encuesta de PITEC, identificamos a las PYMES madrileñas que podrían ser más proclives a mantener una relación fructífera con los OPIS, dada su experiencia previa en el uso de información científico-...

Abstract: The social and economic factors leading to selfless acts such as charitable donations have been a central concern in the social sciences. We contribute to this scholarship with an artefactual field experiment in Peru where subjects anonymously decide how much of their endowment they freely donate to the Peruvian government. The standard rational choice model and several well-known models of non-selfish preferences predict zero giving. Yet we observe that around 75% of the subjects give something (N = 164), with substantial heterogeneity. Further, individual donations depend...

Caballero, Adrián and López-Pérez, R.

Abstract: A recent experimental literature has documented that people are (sometimes) asymmetric updaters: Good news are over-weighted, relative to bad news. We contribute to this literature with a novel experimental test of a potential mechanism of asymmetric updating, that is, that people recall better the positive than the negative evidence. In our design, this account predicts inflated posteriors regarding some future financial prize. Contrary to that, the average subject (slightly) underestimates the mode of the posterior beliefs about that payoff prospect. Although subjects tend to...

Abstract: Economic theories of optimism provide different rationales for the phenomenon of motivated reasoning, and a recent empirical literature has tested some of them, with mixed results. We contribute to this literature with a novel experimental test of two mechanisms, according to which optimism is respectively predicted when (1) the potential material losses due to the bias are relatively small or (2) the cognitive costs of the bias are small enough. In our design, these two accounts predict inflated expectations regarding some future payoff. Contrary to that, the average subject...

Abstract: This study contributes to the recent experimental literature addressing the role of team formation in overcoming coordination failure in weakest-link games. We investigate the endogenous formation of teams in fixed neighborhoods in which it is not possible to exclude players from influencing the weakest-link. Our experimental results show that team formation helps in overcoming the coordination problem, raises equilibrium provision levels, but falls short of providing the Pareto-optimal contribution. As the problem of multiplicity of Nash equilibria in weakest-link games is...

Pledge and implement bargaining in the Paris Agreement on climate change

Alejandro Caparrós

Abstract: This paper analyzes a multilateral bargain game motivated by the Paris Agreement on climate change. Countries submit pledges, which can be revoked although this implies reputational costs. Pledges, which do not need to be accepted by other countries, detail intended abatement efforts and can be conditional or unconditional, according to whether they depend on transfers. As the process is repeated, incomplete long-term provisions are also considered. The analysis shows the conditions under which, despite its weakness, the Paris Agreement can bring the world to the first best, or...

Abstract: A preference reversal (PR) refers to behavior that violates revealed preference or is simply incoherent – i.e., not explainable by a rational ordering. In a classical PR experiment, for instance, participants often exhibit greater risk aversion in a Choice-based revelation procedure than in an Evaluation-based one, i.e., choose the safer of two gambles but express a higher monetary valuation for the riskier. We conjecture that PRs are partly due to the interaction between attention and task mode, and explore three compatible explanations using eye-tracking techniques....

Abstract: People often extrapolate from data samples, inferring properties of the population like the rate of some event, class, or group ‒e.g. the percent of female scientists, the crime rate, the chances to suffer some illness. In many circumstances, though, the sample observed is non-random, i.e., affected by sampling bias. For instance, news media rarely display (intentionally or not) a balanced view of the state of the world, focusing particularly on dramatic and rare events. In this line, recent literature in Economics hints that people often fail to account for sample selection in...
