Einkommens- und Vermögensunterschiede drei Jahrzehnte nach der Wiedervereinigung
Charlotte Bartels, Theresa Neef
Ost und West. Frei, vereint und unvollkommen. Bericht des Ostbeauftragten 2024,
2024
Abstract
Mehr als 30 Jahre nach der deutschen Wiedervereinigung sind die wirtschaftlichen Ressourcen der Bewohnerinnen und Bewohner Ostdeutschlands weiterhin deutlich geringer als in Westdeutschland. Ostdeutsche Löhne liegen immer noch knapp 30 Prozent unter den westdeutschen Löhnen. Das durchschnittliche Vermögen der ostdeutschen Haushalte beträgt weniger als 50 Prozent des westdeutschen Durchschnitts. Im Folgenden beleuchten wir Unterschiede und Gemeinsamkeiten der Einkommens- und Vermögensverteilung in Ost- und Westdeutschland und diskutieren Gründe für das anhaltende ökonomische Gefälle.

Market Feedback Effect on CEO Pay: Evidence from Peers’ Say-on-Pay Voting Failures
Agnes Cheng, Iftekhar Hasan, Feng Tang, Jing Xie
Journal of Financial and Quantitative Analysis,
Vol. 61 (3),
2026
Abstract
This article shows that when a compensation peer firm experiences a significant failure in its say-on-pay (SOP) voting, the focal firm’s stock price is adversely affected, resulting in reduced CEO pay in the subsequent period. This pay-reduction effect is amplified when the board is more powerful, when proxy advisors express concerns about CEO pay, and when the compensation consultant lacks quality. Directors who react to the price drop and cut the CEO’s pay receive higher votes in future director elections, implying a market feedback effect for directors of the focal firm triggered by their peers’ SOP voting failure.

Do courts matter for Firm Value? Evidence from the U.S. Court System
Stefano Colonnello, Christoph Herpfer
Journal of Law and Economics,
Vol. 64 (2),
2021
Abstract
We estimate how US state courts impact firm value by exploiting a US Supreme Court ruling that exogenously changed firms’ exposure to different courts. We find that increased exposure to more business-friendly courts is associated with positive announcement returns. We find no such association for objective court quality. Consistent with the ruling impacting firm value through the legal environment channel, we find that effects are stronger for firms with high litigation exposure. We find that the ruling led to a shift in both the geographic distribution of lawsuits and operations of firms.

Climate Change Economics in Vietnam: Redefining Economic Impact
Christian Otto, Christoph Schult, Thomas Vogt
Energy Economics,
Vol. 160 (August),
2026
Abstract
Vietnam, a low middle-income economy, grapples with considerable climate impacts, primarily driven by heat waves, sea level rise, and tropical cyclones. Under ongoing global warming, these extreme weather events are projected to further intensify. We use a dynamic general equilibrium model to study economic transition dynamics from 2015 to 2100, accounting for heat-induced labor productivity losses, agricultural land loss from sea level rise, and residential property damage from tropical cyclones. We compare a Paris-compatible strong mitigation scenario where global warming is limited to well below 2 °C above preindustrial levels to a strong emission scenario where warming reaches 4–5 °C. We find that the impacts of climate change on output and investment are highly uncertain, with differences between the two emission scenarios remaining statistically insignificant until the end of the century, despite substantially higher climate forcing in the latter. By contrast, consumption losses are significantly larger under the high emission scenario. These negative impacts are primarily driven by heat-induced labor productivity losses, while TCs are the main source of uncertainty. Our findings highlight the need for analytical frameworks to capture the different channels through which climate and climate change affect economic development, rather than focusing mainly on output-related damage, as done in many existing studies.

Individualism and the Formation of Human Capital
Katharina Hartinger, Sven Resnjanskij, Jens Ruhose, Simon Wiederhold
Journal of the European Economic Association,
Vol. 24 (3),
2026
Abstract
More individualistic countries experience higher economic growth. We provide evidence for a human-capital-based explanation of the growth effects of individualism. Using data from the largest international adult skill assessment, we establish that individualism shapes human capital formation. We identify the effects of individualism by exploiting variation between migrants at the origin-country, origin-language, and person level. Migrants from more individualistic cultures have higher cognitive skills and larger skill gains over time. They also invest more in their skills over the life cycle, as they acquire more years of schooling and are more likely to participate in adult education activities. Individualism is more important in explaining adult skill formation than any other cultural trait that previous literature has emphasized. In the labor market, more individualistic migrants earn higher wages and are less often unemployed. We show that our results cannot be explained by selective migration or omitted origin-country variables.
