We introduce a new criterion to compare the properties of mechanisms when the solution concept used induces multiple solutions. Our criterion generalizes previous approaches in the literature. We use our criterion to compare the stability of constrained versions of the Boston (BOS) and deferred...

We compare the manipulability of school choice mechanisms based on the occurrence of dominant strategies. We characterize dominant strategies in the constrained versions of the deferred acceptance (DA) and Boston (BOS) mechanisms. We leverage our characterizations to show that dominant...

School choice mechanisms are typically constrained, with students allowed to report preferences on a limited number of schools only Under constraints, the deferred acceptance mechanism (DA) is manipulable and it is unclear how students should play in DA. In order to provide advice to...

Poverty and mortality are arguably the two major sources of loss of well-being. Most mainstream measures of human development capturing these two dimensions aggregate them in an ad-hoc and controversial way. This paper develops a new index aggregating the poverty and the mortality observed in a...

Simple welfare indices such as mean income are ubiquitous but not distribution sensitive. In contrast, existing distribution sensitive welfare indices are rarely used, often because they are difficult to explain and/or lack intuitive units. This paper proposes a simple new distribution sensitive...

The Covid-19 pandemic has brought about massive declines in wellbeing around the world. This paper seeks to quantify and compare two important components of those losses â increased mortality and higher poverty â using years of human life as a common metric. We estimate that almost 20 million...
