Title :The Taxation of Couples
Abstract : This paper studies the tax treatment of couples. We develop two different approaches. One is tailored to the analysis of tax systems that stick to the principle that the tax base for couples is the sum of their incomes. One is tailored to the analysis of reforms toward individual taxation. We study the US federal income tax since the 1960s through the lens of this framework. We find that, in the recent past, realizing efficiency gains requires lowering marginal tax rates for secondary earners. We also find that revenue-neutral reforms towards individual taxation are in the interest of couples with high secondary earnings while couples with low secondary earnings are worse off. The support for such a reform recently passed the majority threshold. It is rejected, however, by a Rawlsian social welfare function. Thus, there is a tension between Rawlsian and Feminist notions of social welfare.

06 Feb, 15:00 - 16:00
You are kindly invited to the next Joint Firm Analysis Seminar of the NBB, KUL, UA, UCL, UGent, UHasselt, ULB, ULg and UMons
Given by Johannes Boehm (Geneva Graduate Institute)
on Trade and the End of Antiquity
joint work with Thomas Chaney
on Thursday, 6 February at 16.30 in in the Auditorium of the National Bank of Belgium (Room A), rue Montagne aux Herbes potagères 61, 1000 Brussels.
Abstract:
What caused the end of antiquity, the shift of economic activity away from the Mediterranean towards northern Europe and the Middle East? To answer this question, we assemble a database of hundreds of thousands of ancient coins from the 4th to the 10th century, estimate a dynamic model of trade and money where coins gradually diffuse along trade routes, and recover regional real consumption time series. Our estimates suggest that technical progress, increased minting, and to a lesser degree the fall in trade flows over the newly formed border between Islam and Christianity contributed to the relative growth of Muslim Spain and the Frankish lands of northern Europe and the decline of the Roman-Byzantine world. Our estimates are consistent with the increased urbanization of western and northern Europe relative to the eastern Mediterranean from the 8th to the 10th century.
Prof. Boehm will be present at the bank on 6 February and there are a limited number of slots for a meeting with him.
Please contact us at nbbfirmanalysis.seminar@nbb.be if you are interested.
Whilst we encourage your physical presence, we also offer the possibility to follow the seminar online via Teams. Please send an email to nbbfirmanalysis.seminar@nbb.be to obtain the link.

Title : Engineering Commonality
Abstract : Mutual trust, whether it results from shared goals, empathy, a long-lasting relationship, or common priors, is the lubricant that makes organizations and society operable. Besides designing team incentives when feasible, the latter accordingly stress what unites their members and abhor what divides. They regulate acceptable discourse, facilitate team building, spread commonality narratives, and rewrite history. The paper builds a framework in which members of a team are more likely to exert effort if their teammates do (strategic complementarity) and they can trust each other (congruence). They predict congruence on the task based on experiments, for example by exchanging on a variety of otherwise task-irrelevant traits. The paper obtains the optimal communication protocols for the agents and for the organization and asks whether these protocols are robust to misrepresentations and to additional exchange of information. It also studies the organization’s communication about membership and values.
This event is FREE and open to all. For organizational purposes, please register by February 3 : https://forms.office.com/e/t79MFXe67E

Title: Matching on gender and sexual orientation, with Marion Goussé (CREST)
Abstract: In spite of the increasing share of individuals who identify as bisexuals or report sexual attraction to both men and women, 89% of partnered bisexuals in the U.S. are in a different-sex relationship. Moreover, 14% of partnered gay men and lesbians have a partner of the opposite gender. In order to better understand these mating patterns, we estimate a multidimensional matching model of the marriage market where individuals differ by gender, sexual orientation, age, education, and race. The novelty is that the partner's gender is endogenously chosen conditional on the agent's sexual orientation, and is subject to trade-offs that depend on both the agents' preferences and the pool of potential partners. We show that same-sex couples experience lower gains from live-in relationships, a difference we refer to as the "same-sex penalty". We find a relatively large penalty for male same-sex couples, in both Germany and the U.S., although it has decreased in recent years. Moreover, we identify a smaller penalty for female same-sex couples in some regions of the U.S., but not in the Northeast, in the West, nor in Germany. Through a counterfactual experiment, we show that, absent this penalty, the share of same-sex couples in the U.S. would increase by about 50%, from 1.35% to 2.06% of all couples. Finally, we also show that a 10% increase in the men-to-women gender ratio would lead to a modest, but positive increase in the odds that a man is in a same-sex relationship (+1.8%), and to an almost symmetric decrease in the odds that a woman is in a same-sex relationship (-1.9%).

Title: Belgian wealth inequality, 1935-2022
Abstract: In the absence of a wealth register, Belgian wealth inequality needs to be estimated. Here I apply the mortality multiplier approach to Belgian inheritance tax tabulations and administrative microdata, collectively covering 1935 to 2022. Belgian wealth inequality has strongly declined during the 20th century and seems relatively stable in recent years. I triangulate my estimates with national accounts aggregates and previous work on Belgian wealth inequality. The evolution of Belgian wealth inequality is in line with other European countries for which long-run estimates are available.

Title : Functional additive models for forms of plane curves and their visualization:
Abstract : In many imaging data problems, the coordinate system of recorded objects is arbitrary or explicitly not of interest. Statistical shape analysis addresses this by identifying the object of analysis as the "shape" of observation, i.e., its equivalence class modulo translation, rotation and re-scaling, or as its "form" modulo translation and rotation. A flexible additive regression framework is introduced for modeling the shape or form of planar (potentially irregularly sampled) curves and/or landmark configurations in dependence on scalar covariates. The focus is on an analysis of the form of cell outlines generated from a cellular Potts model in dependence on different metric biophysical model parameter effects (including smooth interactions). Graphic illustration usually plays an essential role in the practical interpretation of smooth (non-linear) additive model effects but becomes a challenging task when the response presents an (equivalence class of) planar curves or landmark configurations. Therefore, a novel visualization for multidimensional functional regression models is also suggested. Analogous to principal component analysis often used for the visualization of functional data, a suitable tensor-product factorization decomposes each covariate effect. After decomposition, the main effect directions can be illustrated on the level of curves, while the effect into the respective direction is visualized by standard effect plots for scalar additive models.

title : Out of the Shadows and into the Classroom:Immigrant Legalization, Hispanic Human Capitaland Hispanic Representation on School Boards
AbstractTo what extent does immigrant legalization foster human capital accumulation andtranslate into long-run economic mobility and political representation? I address thesequestions by comparing outcomes across people, public schools and counties in the USwith differential exposure to the 1986 Immigration Reform and Control Act (IRCA), whichdocumented millions of Hispanic migrants. The IRCA increases Hispanic public schoolenrollment and high school completion, while whites sort out of public education andinto private schooling. In the long run, legal status boosts Hispanic college completion,access to high-skill occupations, and incomes. It also increases Hispanic school boardrepresentation and political mobility across locally elected public office but does not affectlocal government structure. These findings highlight legalization as a driver of humancapital investment and economic and political mobility. (JEL: I21, J15, H52)
