The Evolution of Child-Related Gender Inequality in Germany and The Role of Family Policies, 1960-2018
Author:
Abstract:
Using German administrative data from the 1960s onward, this paper (i) examines the long-term evolution of child-related gender inequality in earnings and (ii) assesses the impact of family policies on this inequality. Our first (methodological) contribution is a decomposition approach that separates changes in child-related inequality into three components: the share of mothers, child penalties, and potential earnings of mothers (absent children). Our second contribution is a comprehensive analysis of child-related gender inequality in Germany. We derive three sets of findings. First, child penalties (i.e., the share of potential earnings mothers lose due to children) have increased strongly over the last decades. Mothers who had their first child in the 1960s faced much smaller penalties than those who gave birth in the 2000s. Second, the fraction of overall gender inequality in earnings attributed to children rose from 14% to 64% over our sample period. We show that this trend resulted not only from growing child penalties but also from rising potential earnings of mothers. Intuitively, in later decades, mothers had more income to lose from child-related career breaks. Third, we show that parental leave expansions between 1979 and 1992 amplified child penalties and explain nearly a third of the increase in child-related gender inequality. By contrast, a parental benefit reform in 2007 mitigated further increases.

Pareto-Improvements, Welfare Trade-Offs and the Taxation of Couples
Author:
Abstract:
We develop a theory of tax reforms for a setting with multi-dimensional heterogeneity amongst taxpayers and multiple economic decisions that are all subject to fixed and variable costs. The theorems in this paper provide a complete characterization of the conditions under which Pareto- or welfare-improving tax reforms exist. We focus on one application, the taxation of couples, and present a detailed analysis of the behavioral responses to taxation in this setting. Squaring the theorems with this analysis yields sufficient statistics for the existence of Pareto- or welfare-improving tax reforms. In the empirical part, we apply them to US data. Our findings include the following: Tax rates on secondary earnings are inefficiently high when secondary earnings are close to primary earnings. Also, reducing the tax system’s degree of jointness is not Pareto-improving. Whether it raises welfare depends on a trade-off between poverty alleviation and gender balance.

Just Cheap Talk? Investigating Fairness Preferences in Hypothetical Scenarios
Author:
Abstract:
The measurement of preferences often relies on surveys in which individuals evaluate hypothetical scenarios. This paper proposes and validates a novel factorial survey tool to measure fairness preferences. We specifically examine whether a non-incentivized survey captures the same distributional preferences as an impartial spectator design, where choices may apply to a real person. In contrast to prior studies, our design involves high stakes, with respondents determining a real person’s monthly earnings, ranging from $500 to $5,700. We find that the non-incentivized survey module yields nearly identical results compared to the incentivized experiment and recovers fairness preferences that are stable over time. Furthermore, we show that most respondents adopt intermediate fairness positions, with fewer exhibiting strictly egalitarian or libertarian preferences. These findings suggest that high stake incentives do not significantly impact the measurement of fairness preferences and that non-incentivized survey questions covering realistic scenarios offer valuable insights into the nature of these preferences.

Automation and Polarization
Author:
Abstract:
We develop an assignment model of automation. Each of a continuum of tasks of variable complexity is assigned to either capital or one of a continuum of labor skills. We characterize conditions for interior automation, whereby tasks of intermediate complexity are assigned to capital. Interior automation arises when the most skilled workers have a comparative advantage in the most complex tasks relative to capital, and because the wages of the least skilled workers are sufficiently low relative to their productivity and the effective cost of capital in low-complexity tasks. Minimum wages and other sources of higher wages at the bottom make interior automation less likely. Starting with interior automation, a reduction in the cost of capital (or an increase in capital productivity) causes employment and wage polarization. Specifically, further automation pushes workers into tasks at the lower and upper ends of the task distribution. It also monotonically increases the skill premium above a skill threshold and reduces the skill premium below this threshold. Moreover, automation tends to reduce the real wage of workers with comparative advantage profiles close to that of capital. We show that large enough increases in capital productivity ultimately induce a transition to low-skill automation and qualitatively alter the effects of automation - thereafter inducing monotone increases in skill premia rather than wage polarization.

Redistributive Income Taxation with Directed Technical Change
Author:
Abstract:
What are the implications of (endogenous) directed technical change for the design of redistributive income taxes? I study this question in a Mirrleesian economy augmented to include endogenous technology development and adoption choices by firms. Under certain conditions, any progressive tax reform induces technical change that compresses the pre-tax wage distribution. The key intuition is that progressive tax reforms tend to increase labor supply of less skilled relative to more skilled workers, which induces firms to develop and use technologies that are more complementary to the less skilled. These directed technical change effects make the optimal tax scheme more progressive, raising marginal tax rates at the right tail of the income distribution and lowering them at the left tail. For reasonable calibrations, the impact of directed technical change on the optimal tax is quantitatively important: optimal marginal tax rates are reduced substantially for incomes below the median and increase monotonically over the bulk of the income distribution instead of being U-shaped (as in most of the previous literature).

The Taxation of Couples
Author:
Abstract:
Are reforms towards individual taxation politically feasible? Are they desirable from a welfare perspective? We develop a method to answer such questions and apply it to the US federal income tax since the 1960s. Main findings are: As of today, Pareto-improvements require a move away from joint taxation. Revenue-neutral reforms towards individual taxation are not Pareto-improving, but attract majoritysupport. Such reforms are rejected by Rawlsian welfare measures and supported by ones with weights that are increasing in the secondary earner’s income share. Thus, there is a tension between the welfare of “the poor” and the welfare of “working women.”
