Cultural differences and immigrants' wagesJournal articleMorgan Raux, Labour Economics, Volume 82, pp. 102361, 2023

Integration of immigrants into their host society is at the core of the public debate in most OECD countries. Im-migrant integration includes two distinct dimensions: cultural and economic integration. This paper investigates the interplay between these two processes and presents three main results. First, it documents that immigrants from more culturally distant countries earn lower wages when they enter the German labor market. Second, it highlights that these wage differences progressively diminish over years spent in Germany and even disappear in some cases. For instance, the wage gap associated with a one standard deviation difference in religious and genetic distance disappears after 15 to 20 years. Finally, the paper provides evidence that immigrants who ex-perience a greater increase in cultural assimilation experience more wage growth as well. Taken together, these results suggest that the cultural assimilation process can benefit the economic integration of immigrants.

Bread and Social Justice: Measurement of Social Welfare and Inequality Using AnthropometricsJournal articleMohammad Abu-Zaineh et Ramses H. Abul Naga, Review of Income and Wealth, Volume 69, Issue 2, pp. 265-288, 2023

We address the question of the measurement of health achievement and inequality in the context of variables exhibiting an inverted-U relation with health and well-being. The chosen approach is to measure separately achievement and inequality in the health increasing range of the variable, from a lower survival bound a to an optimum value m, and in the health decreasing range from m to an upper survival bound b. Because in the health decreasing range, the equally distributed equivalent value associated with a distribution is decreasing in progressive transfers, the paper introduces appropriate relative and absolute achievement and inequality indices to be used for variables exhibiting a negative association with well-being. We then discuss questions pertaining to consistent measurement across health attainments and shortfalls, as well as the ordering of distributions exhibiting an inverted-U relation with well-being. An illustration of the methodology is provided using a group of five Arab countries.

Can low-cost, scalable, online interventions increase youth informed political participation in electoral authoritarian contexts?Journal articleRomain Ferrali, Guy Grossman et Horacio Larreguy, Science Advances, Volume 9, Issue 26, pp. eadf1222, 2023

Young citizens vote at relatively low rates, which contributes to political parties de-prioritizing youth preferences. We analyze the effects of low-cost online interventions in encouraging young Moroccans to cast an informed vote in the 2021 elections. These interventions aim to reduce participation costs by providing information about the registration process and by highlighting the election’s stakes and the distance between respondents’ preferences and party platforms. Contrary to preregistered expectations, the interventions did not increase average turnout, yet exploratory analysis shows that the interventions designed to increase benefits did increase the turnout intention of uncertain baseline voters. Moreover, information about parties’ platforms increased support for the party closest to the respondents’ preferences, leading to better-informed voting. Results are consistent with motivated reasoning, which is surprising in a context with weak party institutionalization.

Determinants of compliance with fiscal rules: Misplaced efforts or hidden motivations?Journal articleCarolina Ulloa-Suárez, European Journal of Political Economy, Volume 78, pp. 102399, 2023

This paper empirically examines which factors have influenced numerical compliance with fiscal rules in Latin American and Caribbean countries over the period 2000 to 2020. We use logistic regression models to associate three groups of specific factors with a greater or lesser probability of compliance with the rule: the macroeconomic and political environment of the countries and the design features of the enforced rules. We find that only changes in the macroeconomic and political context affect the probability of compliance with the enforced rules. In contrast, the institutional design of the fiscal rules does not seem to play an essential role in the compliance outcome. This result suggests that adjustments in this direction are not decisive for rule compliance.

The birthplace bias of teleworking: Consequences for working conditionsJournal articleEva Moreno Galbis et Felipe Trillos Carranza, LABOUR, Volume 37, Issue 2, pp. 280-318, 2023

The massive shift towards teleworking during the COVID pandemic relatively deteriorated working conditions of people occupying positions that could not be teleworked because they were more exposed to the risk of infection. Exploiting French data, we analyse the differential changes in sorting across occupations of immigrants and natives during years preceding the pandemic. Immigrants sorted relatively more into occupations intensive in non-routine manual tasks. These occupations cannot be teleworked. We find an increase in immigrants' sorting into occupations intensive in non-routine interactive and analytical tasks. However, in contrast with natives, immigrants were moving away from occupations intensively using new technologies.

Other-regarding preferences and giving decision in a risky environment: experimental evidenceJournal articleMickael Beaud, Mathieu Lefebvre et Julie Rosaz, Review of Economic Design, Volume 27, Issue 2, pp. 359-385, 2023

We investigate whether and how an individual giving decision is affected in risky environments in which the recipient’s wealth is random. We demonstrate that, under risk neutrality, the donation of dictators with a purely ex post view of fairness should, in general, be affected by the riskiness of the recipient’s payoff, while dictators with a purely ex ante view should not be. Furthermore, we observe that some influential inequality aversion preferences functions yield opposite predictions when we consider ex post view of fairness. Hence, we report on dictator games laboratory experiments in which the recipient’s wealth is exposed to an actuarially neutral and additive background risk. Our experimental data show no statistically significant impact of the recipient’s risk exposure on dictators’ giving decisions. This result appears robust to both the experimental design (within subjects or between subjects) and the origin of the recipient’s risk exposure (chosen by the recipient or imposed on the recipient). Although we cannot sharply validate or invalidate alternative fairness theories, the whole pattern of our experimental data can be simply explained by assuming ex ante view of fairness and risk neutrality.

Profit Effects of Consumers’ Identity Management: A Dynamic ModelJournal articleDidier Laussel, Ngo Van Long et Joana Resende, Management Science, Volume 69, Issue 6, pp. 3602-3615, 2023

We consider a nondurable good monopolist that collects data on its customers in order to profile them and subsequently practice price discrimination on returning customers. The monopolist’s price discrimination scheme is leaky in the sense that an endogenous fraction of consumers choose to incur a privacy cost to conceal their identity when they return in the following periods. We characterize the Markov perfect equilibrium of the game under two alternative customer profiling regimes: full information acquisition (FIA) and purchase history information (PHI). In both cases, we find that, contrary to what could be expected, the monopolist’s aggregate profit is not monotonically increasing in the level of the privacy cost, but a U-shaped function of it, leading to ambiguous profit effects: a reduction in privacy costs increases the fraction of customers who choose to be anonymous (detrimental profit effect), but it also softens the firm’s introductory price, reducing the pace at which prices targeted to new customers fall over time (positive profit effect). When comparing results under FIA and PHI, we find that market expansion is faster, and more customers conceal their identity under FIA than under PHI. Equilibrium profits are also higher in the FIA case. Although equilibrium profits are U-shaped functions of the privacy cost in both profiling regimes, they tend to be globally decreasing with the privacy cost under PHI and globally increasing under FIA.

Scale-dependent and risky returns to savings: Consequences for optimal capital taxationJournal articleEddy Zanoutene, Journal of Public Economic Theory, Volume 25, Issue 3, pp. 532-569, 2023

I present a model of optimal capital taxation where agents with heterogeneous labor productivity randomly draw their rate of return to savings. Because of scale dependence, the distribution of rates of returns can depend on the amount saved. Uncertainty in returns to savings yields an insurance rationale for taxing capital on top of labor income. I first show that, because of scale dependence, agents making the same saving decision should access the same rate of return at the optimum. I then constrain the information set of the government and show that, as soon as return are uncertain, positive capital income taxation is needed at the optimum. The optimal linear tax on capital income trades off insurance with distortions to both savings and to the rate of return in a context of scale dependence. Eventually, I argue that scale dependence in and of itself is not sufficient to justify capital taxation on top of labor income taxes. These results are still valid when agents can optimize between a risk-free and a risky-asset that can both exhibit scale dependence.

Forward to the Past: Short-Term Effects of the Rent Freeze in BerlinJournal articleAnja M. Hahn, Konstantin A. Kholodilin, Sofie R. Waltl et Marco Fongoni, Management Science, 2023

In 2020, Berlin introduced a rigorous rent-control policy responding to soaring prices by capping rents: the Mietendeckel (rent freeze). The German Constitutional Court revoked the policy only one year later. Although successful in lowering rents during its duration, the consequences for Berlin’s rental market and close-by markets are per se not clear. This article evaluates the short-term causal supply-side effects in terms of prices, quantities, and landlords’ strategic behavior. We develop a theoretical framework capturing the key features of first-generation rent control policies and Berlin-specific aspects. Using a rich pool of detailed rent advertisements, predictions are tested, and further empirical causal inference techniques are applied for comparing price trajectories of dwellings inside and outside the policy’s scope. Mechanically, advertised rents drop significantly upon the policy’s enactment. A substantial rent gap along Berlin’s administrative border emerges, and rapidly growing rents in Berlin’s (unregulated) adjacent municipalities are observed. Landlords started adopting a hedging strategy insuring themselves against the risk of contractually long-term fixed low rents following a potentially unconstitutional law. Whereas this hedge was beneficial for landlords, the risk was completely borne by tenants. Moreover, the number of available properties for rent dropped significantly, a share of which appears to be permanently lost for the rental sector. This hampers a successful housing search for first-time renters and people moving within the city. Overall, negative consequences for renters appear to outweigh positive ones.

Education and polygamy: Evidence from CameroonJournal articlePierre André et Yannick Dupraz, Journal of Development Economics, Volume 162, pp. 103068, 2023

Has secular education contributed to the decline of polygamy in Africa? To answer this question, we study a wave of public school construction in late-colonial Cameroon. Our difference-in-differences and event-study specifications show that school openings have simultaneously increased education and the chances to be in a polygamous union for men and, more surprisingly, for women. We estimate a structural model of marriage to explain why education made women more likely to be in a polygamous union. The main estimated channel is marriage to educated men who are more often polygamists than uneducated men, not direct preferences for polygamy.
