Highlights Degraded trust and cohesion within a country have large socioeconomic impacts but also present risk for collective survival in the face of a pandemic Human mobility decreases in Europe during generalized lockdowns in March 2020 The shelter-in-place policy is significantly more effective, i.e. mobility reduction in non-necessary activities is larger, in regions with higher levels of political trust Mobility reduction is positively related to the daily stringency of national policies and this association is stronger in high-trust regions The trust effect also translates in large differences in terms of COVID-19 mortality growth rate.

Measurement differences are netted out by using a harmonized empirical approach and comparable data sources. We find that own-wage elasticities are relatively small and much more uniform across countries than previously thought. Differences exist nonetheless and are found not to arise from different tax-benefit systems or demographic compositions across countries. Thus, we cannot reject that countries have genuinely different preferences. Three other results, important for welfare analysis, are consistent over all countries: the extensive (participation) margin dominates the intensive (hours) margin; for singles, this leads to larger labor supply responses in low-income groups; income elasticities are extremely small everywhere. Finally, the results for cross-wage elasticities in couples are opposed between regions, consistent with complementarity in spouses' leisure in the US versus substitution in spouses' household production in Europe.JEL Classification: C25, C52, H31, J22

To assess the impact of tax-bene…t policy changes on income distribution over time, we suggest a methodology based on counterfactual simulations. We start by decomposing changes in inequality/poverty indices into three contributions: reforms of the tax-bene…t structure (rules, rates, etc.), changes in nominal levels of market incomes and tax-bene…t parameters (bene…t amounts, tax bands, etc.), and all other changes in the underlying population (market income inequality, demographic composition, employment level, etc.). Then, the decomposition helps to extract an absolute measure of the impact of tax-bene…t changes on inequality when evaluated against a distributionally-neutral benchmark, i.e. a situation where tax-bene…t parameters are adjusted in line with income growth.We apply this measure to assess recent policy changes in twelve European countries. Finally, the full decomposition allows quantifying the relative role of policy changes compared to all other factors. We provide an illustration on France and Ireland and check the sensitivity of the results to the decomposition order.Key Words : Tax-bene…t policy, inequality, poverty, decomposition, microsimulation.

As their environment changes, migrants constitute an interesting group to study the e¤ect of relative income on subjective well-being. This paper focuses on the huge population of rural-to-urban migrants in China. Using a novel dataset, we …nd that the well-being of migrants depends on several reference groups: it is negatively a¤ected by the income of other migrants and workers of home regions; in contrast, we identify a positive, 'signal' e¤ect vis-à-vis urban workers: larger urban incomes indicate higher income prospects for the migrants. These e¤ects are particularly strong for migrants who wish to settle permanently, decline with years since migrations and change with other characteristics including work conditions and community ties.

Poverty measures in developing countries often ignore the distribution of resources within families and the gains from joint consumption. In this paper, we estimate the allocation process and adult economies of scale in households from Côte d'Ivoire using a collective model of household consumption. Identi…cation relies on the observation of adult-speci…c goods, as in the Rothbarth method, and a joint estimation on couples and singles. Results show that children's shares are small and decline quickly with household size. It results that child poverty, measured on the basis of individual allocations within families, is much larger than in traditional measures ignoring intrahousehold inequality. Adult poverty is smaller because parents are highly compensated by the scale economies due to joint consumption.
