Low birth rates have modest long run negative effects, after good effects for a few decades, and raising birthrates exacerbates dependency. A giant, apparently permanent, disconnect between expert opinion (e.g., below) versus manufactured panic hype on this issue pubs.aeaweb.org/doi/pdfplus/...
My conclusion is that much of the worry about sub-replacement fertility is
overstated. Quantitatively, the net effect of even a large fertility reduction on the
US economy would be a relatively small decline in the standard of living. Comparing
demographic steady states and focusing on the most easily quantified channels,
a version of the United States with a total fertility rate of one child per woman
would have consumption per capita that was 8.7 percent lower than a version of
the country where the TFR was two. In the first four decades of the transition
following a decline in fertility below the replacement rate, consumption is actually
higher than it would have been if fertility had remained constant. Indeed, much of
the sturm und drang regarding the economic effects of current population aging is
related to the ending of such a transitory period of good times that resulted from
fertility declining from its Baby-Boom highs to near replacement, starting in the
1960s. Finally, it is important to note that any attempt to fix the economic problems
stemming from low fertility by raising the birth rate will entail a period of higher
overall dependency in the decades that it takes the resulting children to become
productive adults.

JOB! I'm hiring a postdoc for 2 years on my ERC MaMo project. Looking for someone with strong quant methods, ongoing work close to the project's aims, and a desire to publish in sociology. Start flexible in the next 12 months. Formal call out shortly, but contact me first.
Markets and Mobility: How Employers Structure Economic OpportunityIntergenerational mobility, measuring the ability to achieve economic success regardless of family background, is a critical reflection of a society’s commitment to equality of opportunity. Rising income inequality has raised concerns about the potential erosion of upward mobility. While education has traditionally been viewed as the path to mobility, its transformative power is facing challenges in a rapidly evolving job market. This project reorients the focus of intergenerational mobility research by highlighting the labor market as an arena for the reproduction of advantage. It employs a comparative approach, using administrative data from four countries: Sweden, Austria, England, and the United States. It also incorporates evidence from a broader set of nations through cross-national surveys, longitudinal household surveys, labor force surveys, secondary data, and digital trace data. The project employs cutting-edge empirical methods, including quasi- experimental designs, event studies, within-family comparisons, decomposition analyses, counterfactual simulations, and diagnostic checks to rigorously assess the extent of inequalities in the labor market. The research investigates how family background influences the sorting of individuals to employers and workplaces, accounting for education and occupation, and explores variations in career progression within and between employers. It comprehensively catalogues and assesses mechanisms shaping workplace inequality, contributing to the development of social closure theory. Additionally, the project evaluates intervention strategies, encompassing both employer practices and government actions, to promote fair opportunity in the labor market.
