Both univariate and bivariate measures remain debated because there is no clear consensus on how to define and quantify socially necessary unpaid work, the time that money cannot substitute for, across household types and income levels. Existing approaches typically adjust monetary poverty lines for unpaid work responsibilities or rely on average unpaid work time, while assuming a fixed substitutability between time and money. Such measures fail to capture the joint constraints that shape household living standards. Using household-level data from the 2017 and 2019 Panel Study of Income Dynamics (PSID), the analysis supports setting 60 percent of the median as the threshold for socially necessary unpaid work in single-adult households without children and applying equivalence scales for other household types. The bivariate relative poverty line (BRPL) framework further defines nonlinear bundles of unpaid household work and food expenditure that mark the threshold for living above the poverty line. The results show that 10.1 percent of oneand two-adult households fall below the BRPL despite not being poor according to univariate measures, underscoring the importance of jointly considering time and money in assessing household living standards and poverty. 2026-01-01T00:00:00Z https://hdl.handle.net/10419/342507 Title: Seeking scientific consensus: An expert survey on the replication debate between Acemoglu et al. (2001) and Albouy (2012) Authors: Buchner, Martin; Rose, Julian; Johannesson, Magnus; Malan, Mandy; Ankel-Peters, Jörg Abstract: The publication of contradictory replications often sparks persistent disputes between replicators and original authors. We investigate whether experts converge toward consensus in the prominent debate between Acemoglu, Johnson, and Robinson (AJR, 2001) and Albouy (2012). We recruited 352 experts, including many senior and highly cited economists, primarily from the pool of scholars citing one of the debate articles. We find no consensus on whether the AJR results hold after Albouy's replication, indicating no prevailing interpretation of the debate more than a decade later. Our study demonstrates a potential approach to assessing scientific consensus formation in replication debates and contested literatures. 2026-01-01T00:00:00Z https://hdl.handle.net/10419/342535 Title: Distances in common: (un-)balanced access to public infrastructure in Germany Authors: Cunningham-Vitt, Helena; Weber, Jan David Abstract: Public infrastructure shapes everyday opportunities, yet little is known about how balanced access to work, social reproduction, and leisure as public commons is distributed across households. Existing studies typically assess single services or regional averages, overlooking the relational nature of accessibility of public commons and differences in households' ability to privately substitute for missing public commons. We use German SOEP microdata to construct the relative distance for the three public commons and map households into a ternary space that captures their compositional accessibility. We also develop a Private Substitution Index that identifies the extent to which households rely on private substitutes to offset gaps in public infrastructure. Together, these measures reveal how households position themselves when facing infrastructural trade-offs. Most households exhibit relatively balanced access, but this average masks clear patterns: some live close to work and far from the other public commons, others show the opposite tilt. Urban-rural differences are substantial, while East-West differences are modest. Private substitution capacity rises steeply with income, driven by remote-work feasibility and living-space advantages, whereas public substitution in social reproduction remains limited. These findings show that balanced access to public commons is highly uneven and cannot be understood through single amenities or regional summaries. Policies aimed at spatial justice must consider both positional trade-offs and unequal capacities for private substitution. 2026-01-01T00:00:00Z https://hdl.handle.net/10419/342452 Title: Wealth inequality and the balance of payments constraint in the Global South Authors: Kaltenbrunner, Annina; Maad, Magdalena; Mallmann, Fynn; Rehm, Miriam Abstract: This chapter builds on Robert Blecker's pathbreaking, decades-long contributions (Blecker 1989, 1998, 2013; Blecker and Razmi, 2008) which incorporate, among many other contributions, capital flows to the balance of payments constrained growth literature. We link this to the literature on wealth inequality, which is so far deficient with regard to foreign asset ownership by the Global South. Using empirical evidence from wealth surveys in selected Global South countries as well as macroeconomic data, we argue that the wealthiest groups in the Global South are likely the primary holders of international financial and investment assets, and capital flight by elites will be predominant in these countries. This tightens the balance of payments constraint both directly and through differential returns of the Global South and North. This supports Robert Blecker's argument that we need to consider how Global South economies' subordinate monetary and financial integration interacts with its balance of payments constraint stemming from current account dynamics. 2026-01-01T00:00:00Z
