New paper w/ @hannohilbig.bsky.social: we examine how local exposure to the Great Recession affected politics over the long run. Counties where unemployment rose more in 2007–09 moved toward Democrats, not the populist right. The shift remained visible in 2022.

Trump argues mass deportation will reduce housing costs. In contrast, study finds increased immigration enforcement causes shortages of construction labor and “large reductions in residential construction… [which] is associated with increases in home prices.” www.haas.berkeley.edu/wp-content/u...
How Do Labor Shortages Affect Residential Construction and Housing Affordability?*
Troup Howard„ Mengqi Wang… Dayin Zhang§ April 2023
Abstract
U.S. housing markets have faced a secular shortage of housing supply in the past decade. Most explanations in the literature have tended to focus on the distortionary effect of local housing regulations. This paper provides novel evidence on a less-explored channel affecting housing supply: shortages of construction labor. We exploit the staggered rollout of a national increase in immigration enforcement to identify nega- tive shocks to construction sector employment that are likely exogenous with respect to local housing market conditions. We show that treated counties experience large and persistent reductions in residential construction activity, using measures of both planned and realized construction activity. This reduced housing supply is associated with increases in home prices. We also show that domestic labor supply does not fully offset immigration-related reductions in the construction sector; and that within higher-skilled construction occupations, U.S. workers see net declines as a consequence of increased immigration enforcement.Figure 1: New Constructions and Construction Workers

Figure shows a big reduction in construction workers around 2008-2009 is associated with a big decrease in new housing units. The reduction persists for a decade.

NOTE: This figure plots the time treads of constructed new housing units and construction workers. The green bars are the annual new housing units per 1000 population (left axis) in the U.S. from Census Bureau and HUD. The two dash lines indicates the average levels of new housing units per 1000 population pre- GFC (1968–2007) and post-GFC (2009–2021). The orange line plots the number of construction workers per 1000 population (right axis) from ACS.

“Nostalgia in European Party Politics: A Text-Based Measurement Approach” (with Sven-Oliver Proksch) has been accepted for publication in the British Journal of Political Science! Paper (PDF): muellerstefan.net/papers/bjps_... polisky cssky 1/5
Abstract: Traditional research on political parties pays little attention to the temporal focus of communication but usually concentrates on promises, issue attention, and policy positions. This lack of scholarly attention is surprising, given that voters respond to nostalgic rhetoric and may even adjust issue positions when policy is framed in nostalgic terms. This article presents a novel dataset, PolNos, which contains six text-based measures of nostalgic rhetoric in 1,648 party manifestos across 24 European democracies from 1946 to 2018. The measures combine dictionaries, word embeddings, sentiment approaches, and supervised machine learning. Our analysis yields a consistent result: nostalgia is most prevalent in manifestos of culturally conservative parties, notably Christian democratic, nationalist, and radical right parties. However, substantial variation remains in terms of regional differences and whether nostalgia concerns the economy or culture. We discuss the implications a
