Classical definitions of complementarity are based on cross price elasticities, and so they do not apply, for example, when goods are free. This context includes many relevant cases such as online newspapers and public attractions. We look for a complementarity notion that does not rely on price...

We propose a novel method to model an agent who is imperfectly attentive in the sense that she may consider only some of the alternatives available. Our methodology departs from the standard 'revealed preference' one: we make plausible assumptions on the values to the imperfectly attentive agent...

We study the impact of loss-aversion and the threat of catastrophic damages, which we jointly call threshold concerns, on international environmental agreements. We aim to understand whether a threshold for dangerous climate change is as an effective coordination device for countries to overcome...

Standard economic models of groundwater management impose restrictive assumptions regarding perfect transmissivity (i.e., the aquifer behaves as a bathtub), no external effects of groundwater stocks, observability of individual extraction rates, and/or homogenous agents. In this article, we...

In recent literature a relevant problem has been the relationship between career/personal contact networks and different career paths. In addition, the recent advances in social capital theory have shown the way in which networks impact on personal careers. In particular women's careers appear...

Regarding complex networks, one of the most relevant problems is to understand and to explore community structure. In particular it is important to define the network organization and the functions associated to the different network partitions. In this context, the idea is to consider some new...

We revisit the question whether commodities should be included in investors' portfolios. We employ for the first time a stochastic dominance efficiency (SDE) approach to construct optimal portfolios with and without commodities and we evaluate their comparative performance. SDE circumvents the...

In this paper we calculate the Italian Cities Sustainable Development Goals (SDGs) Composite Index potentially useful for policy analysis and dissemination of sustainable development at local level in Italy. Structured into several dimensions representing 16 out of 17 SDGs adopted by the United...

We compare different indicators of the spread and consequences of the COVID-19 pandemic, developing a novel method to adjust daily COVID-19 deaths to match weekly excess mortality. Focusing on Sweden, the only country that has good data and did not impose a lockdown, we construct counterfactuals...

This paper examines the impact of jury racial composition on trial outcomes using a unique dataset of all felony trials in Sarasota County, Florida between 2004 and 2009. We utilize a research design that exploits day-to-day variation in the composition of the jury pool to isolate quasi-random...
