Abstract
Drawing on detailed career and biographical data of Chinese politicians, this study builds a dynamic social network for all political elites in China and examines the selection process of provincial-level politicians. Using regression and tree-based machine learning techniques and leveraging individuals’ global centrality within political networks, we unveil the relative importance of economic performance, political networks, and career trajectory in determining the selection of provincial leaders. Our findings highlight the critical role of network embeddedness.

Regulating Zombie Mortgages
Jonathan Lee, Duc Duy Nguyen, Huyen Nguyen
Abstract
Using the adoption of Zombie Property Law (ZL) across several US states, we show that increased lender accountability in the foreclosure process affects mortgage lending decisions and standards. Difference-in-differences estimations using a state border design show that ZL incentivizes lenders to screen mortgage applications more carefully: they deny more applications and impose higher interest rates on originated loans, especially risky loans. In turn, these loans exhibit higher ex-post performance. ZL also affects lender behavior after borrowers become distressed, causing them to strategically keep delinquent mortgages alive. Our findings inform the debate on policy responses to foreclosure crises.

IWH-Insolvenztrend: Firmenpleiten auch im Juli auf sehr hohem Niveau
Wie das Leibniz-Institut für Wirtschaftsforschung Halle (IWH) in einer heute veröffentlichten Analyse feststellt, ist die Zahl der Insolvenzen von Personen- und Kapitalgesellschaften in Deutschland im Juli nahezu unverändert geblieben. Die Zahl der betroffenen Arbeitsplätze ging leicht zurück, liegt aber weiterhin deutlich über dem Vor-Corona-Niveau. Die Frühindikatoren deuten auch für die kommenden Monate auf sehr hohe Insolvenzzahlen hin.

The Micro-aggregated Phillips Curve
Daniele Aglio, Eric Bartelsman
IWH Discussion Papers,
Nr. 11,
2026
Abstract
This paper provides theory and evidence on micro-level pricing behavior needed to model an aggregate New Keynesian Phillips Curve. We start with individual firms that are heterogeneous in their production technology and in the demand curves they face. We estimate the parameters of supply and demand curves by utilizing prices and quantities of outputs and factor inputs of firms along with exogenous downstream demand instruments from global input-output and trade data. The research addresses model heterogeneity using a clustering method to classify firms according to their production technology and observed price pass-through. The results show that more productive firms exhibit a lower price response to changes in demand. We find that the aggregate price response to demand shocks will be smaller when more productive firms absorb a larger portion of demand shocks, which generally is the case. At the same time, our results imply that idiosyncratic shifts in demand to clusters of firms with more rapidly rising marginal cost curves, or cost shocks to clusters of firms with high pass-through, will result in a higher aggregate price response. Finally, this paper provides a framework to incorporate heterogeneous pricing behavior into an estimate of the slope of the aggregate Phillips Curve.

Socioeconomic Inequality in Life Expectancy: Perception and Policy Demand in the United States and Germany

IWH Discussion Papers,
Nr. 12,
2026
Abstract
Using survey experiments in the United States and Germany with about 12,000 participants, we study perceptions of socioeconomic inequality in life expectancy and policy demand. Respondents overestimate the rich-poor gap in both countries, judging the life expectancy of the rich roughly accurately but placing that of the poor well below its true level. These misperceptions vary little with political orientation or other characteristics. Correcting them shifts concern but leaves policy demand largely unchanged across general, specific, and real-stakes measures. Instead, demand divides politically, sharply in the United States and much less in Germany, consistent with views about the role of government rather than the inequality itself shaping policy demand.
