The α-MEU model and the smooth ambiguity model are two popular models in decision making under ambiguity. However, the …

Mitigation measures, prevalence response and public mobility during the COVID-19 emergency

Rapa, Noel - 2021

In response to the rapid spread of the COVID-19 pandemic, national governments have implemented a range of mitigation measures designed to limit the transmission of the novel virus. In order to estimate the effects of these "non-pharmaceutical" policies, one needs to properly account for...

Ordering ambiguous acts

Jewitt, Ian; Mukerji, Sujoy - 2017

ambiguity averse relation. First, we define two notions of more ambiguous with respect to such a class. A more ambiguous (I) act … makes an ambiguity averse decision maker (DM) worse off but does not affect the welfare of an ambiguity neutral DM. A more … ambiguous (II) act adversely affects a more ambiguity averse DM more, as measured by the compensation they require to switch …

Symmetry axioms and perceived ambiguity

Klibanoff, Peter; Mukerji, Sujoy; Seo, Kyoungwon - 2017

between the set of relevant measures, shown by KMS [21] to reflect only perceived ambiguity, and the set of measures (which we … perceived ambiguity. Regarding symmetry assumptions, we show that, under relatively mild conditions, a variety of preference … stringent. Only when it is satisfied may the Bewley set be interpreted as reflecting only perceived ambiguity and not also taste …

Can digital information and communication technology (ICT) foster mass political mobilization? We use a novel geo-referenced dataset for the entire African continent between 1998 and 2012 on the coverage of mobile phone signal together with geo-referenced data from multiple sources on the...

Defining rules in cost spanning tree problems through the canonical form

Bergantiños, Gustavo; Vidal-Puga, Juan J. - 2004

We define the canonical form of a cost spanning tree problem. The canonical form has the property that reducing the cost of any arc, the minimal cost of connecting agents to the source is also reduced. We argue that the canonical form is a relevant concept in this kind of problems and study a...

Scientific advice to public policy-making

Papponetti, Valeria; Pinelli, Dino - 2004

A feature of policy-making today is its dependence on scientific advice to deliver public policies that are robust, credible, and effective. This paper discusses how policy-making profits from scientific advice in areas where science and technology are significant. Particular attention is given...

Information design in coalition formation games

Vosooghi, Sareh - 2017

I examine a setting, where an information sender conducts research into a payoff-relevant state variable, and releases information to agents, who consider joining a coalition. The agents' actions can cause harm by contributing to a public bad. The sender, who has commitment power, by designing...

Sufficientarianism

Alcantud, José Carlos R.; Mariotti, Marco; Veneziani, … - 2019

Suflicientarianism is a prominent approach in political philosophy and in policy analyses. However, it is virtually absent from the formal normative economics literature. We analyse suflicientarianism axiomatically in the context of the allocation of opportunities (formalised as chances of...

Majority voting in a model of means testing

Cardak, Buly A.; Glomm, Gerhard; Ravikumar, B. - 2018

We study a model of endogenous means testing where households differ in their income and where the in-kind transfer received by each household declines with income. Majority voting determines the two dimensions of public policy: the size of the welfare program and the means-testing rate. We...
