It is widely acknowledged that the quest for social status can result in an inefficient consumption ”rat-race” and the existing literature has discussed how taxes can mitigate the associated externalities. We suggest a new reason to tax conspicuous consumption. Our paper highlights that taxing status goods can achieve a more equitable distribution of welfare by compressing the status distribution. By curbing the conspicuous consumption of the wealthy, the government renders signaling less informative and increases the share of the social status surplus derived by the less wealthy. This ”status channel” serves as a complement to traditional monetary channels of redistribution.

We study the joint design of nonlinear income and education taxes when the government pursues redistributive objectives. A key feature of our setup is that the ability type of an agent can affect both the costs and benefits of acquiring education. Market remuneration of agents depends on both their innate ability type and their educational choices. Our focus is on the properties of constrained efficient allocations when educational choices are publicly observable at the individual level, but earned income is subject to misreporting. We find that income-misreporting (IM) affects the optimal distortions on income and education and shed light on the reasons for it and mechanisms through which it is done. We show how and why IM strengthens the case for downward distorting the educational choices of low-ability agents. Finally, we find that IM provides another mechanism that makes commodity taxation useful.

We here address the causal relationship between maternal depression and child human capital using UK cohort data. We exploit the conditionally-exogenous variation in mothers’ genomes in an instrumental-variable approach, and describe the conditions under which mother’s genetic variants can be used as valid instruments. An additional episode of maternal depression between the child’s birth up to age nine reduces both their cognitive and non-cognitive skills by 20 to 45% of a SD throughout adolescence. Our results are robust to a battery of sensitivity tests addressing, among others, concerns about pleiotropy and the maternal transmission of genes to her child.

Robots have radically changed the demand for skills and the role of workers in production at an unprecedented pace, with little scope for human capital adjustments. This has affected the job stability and the economic perspectives of large parts of the population in all industrialized countries. Recent evidence on the US labor market has shown negative effects of robots on employment and wages. In this study, we examine how exposure to robots and its consequences on job stability and economic uncertainty have affected individual demographic behavior. To establish this relationship, we use data from the American Community Survey and the International Federation of Robotics and we adopt an empirical strategy that relies on regional industry specialization before the advent of robots combined with the growth of robot adoption by industry. We first document the differential effect of robots on the labor market opportunities of men and women. We find that in regions that were more exposed to robots, the gender-income and labor-force-participation gaps declined. We then show that US regions affected by intense robot penetration experienced a decrease in new marriages, and an increase in both divorce and cohabitation. While there was no change in overall fertility rate, marital fertility declined, and there was an increase in out-of-wedlock births. Our findings are consistent with the hypothesis that the changes in labor markets triggered by robot adoption increased uncertainty, reduced the relative marriage-market value of men, and the willingness to commit for the long term.

Does the gender of the mayor affect the size and composition of public expenditures and revenues? Do male and female mayors react differently to fiscal adjustments? Using a fuzzy regression discontinuity design in close mixed gender races for the election of mayors in Italian municipalities in the period 2000-2015, we find that female mayors collect more revenues and spend more than male ones, both in the current and capital account. When constrained to fiscal adjustments by the central government, in a fuzzy difference-in-discontinuities design we find that female mayors reduce expenditures more than men.

In this paper we set up a simple two-type optimal nonlinear income tax model where the single-crossing condition is violated, and we characterize the properties of a second-best optimum by considering the entire second-best Pareto frontier. The violation of single-crossing is generated by the assumption that agents dier both in terms of market abilities and in terms of their needs for a work-related good. Our analysis highlights several non-standard features of a second-best optimum. In particular, we show that a nonlinear income tax may allow the government to convert a pooling laissez-faire equilibrium into a separating equilibrium, that the second-best Pareto frontier may be discontinuous, and that a second-best optimum may not preserve the income ranking prevailing under laissez-faire. Finally, we also show that at a second-best optimum the labor supply of some agents might be distorted even though no self-selection constraint is (locally) binding in equilibrium.

The stock market influences some of the most fundamental economic decisions of investors, such as consumption, saving, and labor supply, through the financial wealth channel. This paper provides evidence that daily fluctuations in the stock market have important–and hitherto neglected–spillover effects in another, unrelated domain, namely driving. Using the universe of fatal road car accidents in the United States from 1990 to 2015, we find that a one standard deviation reduction in daily stock market returns is associated with a 0.5% increase in the number of fatal accidents. A battery of falsification tests support a causal interpretation of this finding. Our results are consistent with immediate emotions stirred by a negative stock market performance influencing the number of fatal accidents, in particular among inexperienced investors, thus highlighting the broader economic and social consequences of stock market fluctuations.

How does pay-for-performance (P4P) impact productivity, multitasking, and the composition of workers in mission-oriented jobs? These are central issues in sectors like education or healthcare. We conduct a laboratory experiment, manipulating compensation and mission, to answer these questions. We find that P4P has positive effects on productivity on the incentivized dimension of effort and negative effects on the non-incentivized dimension for workers in non-mission-oriented treatments. In mission-oriented treatments, P4P generates minimal change on either dimension. Participants in the non-mission sector – but not in the mission-oriented treatments – sort on ability, with lower ability workers opting out of the P4P scheme.

Public procurement outcomes depend on the ability of the procuring agency to select well-performing suppliers. Should public administrations be granted more or less discretion in their decision making? Using Italian data on municipal public works tendered in the period 2009-2013, we study how a reform extending the scope of bureaucrat discretion affects supplier selection. We find that the share of contracts awarded to politically connected firms increases while the (ex-ante) labor productivity of the winning firm decreases, thus suggesting a potential misallocation of the public funds. These effects are concentrated among lower quality procuring agencies.

According to the existing theoretical literature, there are several channels through which privatization of State-owned enterprises and assets may shape the distribution of income, either increasing or decreasing the level of inequality. Assessing the actual distributional impact of privatization becomes therefore an empirical matter. This paper is a first attempt to empirically investigate the relationship between privatization and income inequality through redistribution, focusing on the role of democratic institutions in developing countries. Using an unbalanced panel of low and middle-countries in the period 1988-2008, we find that an increase in privatization revenue is negatively and significantly correlated with net-income inequality when democratic institutions are well consolidated. All the robustness checks we perform confirm this finding. Thus, our analysis seems to suggest that, in developing countries, policy makers’s choice of implementing divestiture programs while democratizing at the same time may lead to an improvement in income equality.
