There is a huge variation in the size of labor supply elasticities in the literature, which hampers policy analysis. While recent studies show that preference heterogeneity across countries explains little of this variation, we focus on two other important features: observation period and...

Applied welfare analyses of redistributive systems nowadays benefit from powerful tax benefit microsimulation programs combined with administrative data. Arguably, most of the distributional studies of that kind focus on social welfare defined as a function - typically inequality or poverty...

This paper applies recent developments in collective model estimation to elicit the household resource sharing rule, i.e. the amount of household resources accruing to fathers, mothers, and their children among African families in South Africa. We use the 2010/11 South African Income and...

Subjective well-being (SWB) data is increasingly used to perform welfare analyses. Interpreted as 'experienced utility', SWB has recently been compared to 'decision utility' using specific experiments, most often based on stated preferences. Results point to an overall congruence between these...

Multidimensional welfare analysis has recently been revived by money-metric measures based on explicit fairness principles and the respect of individual preferences. To operationalize this approach, preference heterogeneity can be inferred from the observation of individual choices (revealed...

Redistributive systems in Africa are still in their infancy but are constantly expanding in order to finance increasing public spending. This paper aims at characterizing the redistributive potential of six African countries: Ghana, Zambia, Mozambique, Tanzania, Ethiopia, and South Africa. These...

While degraded trust and cohesion within a country are often shown to have large socioeconomic impacts, they can also have dramatic consequences when compliance is required for collective survival. We illustrate this point in the context of the COVID-19 crisis. Policy responses all over the...

In March 2020, shelter-in-place and social-distancing policies have been enforced or recommended all over the world to fight the COVID-19 pandemic. However, strict containment is hardly achievable in low-income countries, as large parts of population are forced to continue income-generating...

Strict containment limits the spread of pandemics but is difficult to achieve when people must continue to work to avoid poverty. A new role is emerging for income support: by enabling people to effectively stay home, it can produce substantial health externalities. We examine this issue using...

Using information on actual ballots rather than survey data, we investigate the impact of immigration on both electoral outcomes and immigrant-related motives underlying political preferences. We take advantage of 94 votes, namely 54 policy propositions and 40 elections for candidates, that took...
