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...

Highlights Ecosystem services make up 60% of ordinary total products in Andalusian HOWs. The GVA of National accounting is 37% that of the Agroforestry Accounting System. Andalusian holm oak environmental asset is 94% of opening total capital. Andalusian holm oak environmental income is 88% of total income. The amenity ecosystem service makes up 46% of total ES in Andalusian HOWs. The ecosystem service of water supply makes up 20% of total ES in Andalusian HOWs.

Abstract The brief description of the sequence of accounts for the products in the SNA and SEEA-EEA guidelines compared...

Highlights The GVA of the Agroforestry Accounting System (AAS) is 1.8 times that of the SNA. The amenity ecosystem services accounts for 34% of the total one for the dehesa. The final economic water accounts for 43% of the environmental income of the dehesa. The total ecosystem services in the rSEEA-EEA overvalues by 20% that of the sAAS. The ecosystem service in the AAS is 2.5 times that of the System of National Accounts.

Highlights Private amenity is the largest ecosystem service in mixed holm oak open woodlands. Landscape ecosystem service (ES) accounts for 29% of sAAS ordinary final product. Farmer and government sAAS ecosystem services present similar values. Changes in environmental assets are positive for all activities except the amenity asset. Ecosystem services of activities are lower than environmental incomes, except in the case of amenity.

Abstract The scientific debate on how to make visible the linkages between the standard System of National Accounts (SNA) and its ongoing satellite...
