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.

Social Capital and Accounting Conservatism

Abstract
We investigate the relationship between county-level social capital in the U.S. and asymmetric earnings timeliness (accounting conservatism). We measure social capital by the strength of civic norms and the density of social networks in a community. We find that firms headquartered in regions with higher social capital have earnings that reflect bad news more quickly than good news. Two potential mechanisms driving this connection are evident in our findings. First, the positive link between social capital and asymmetric earnings timeliness is more pronounced in firms with weaker external oversight, suggesting that social capital compensates for weaknesses in these mechanisms by discouraging managers from delaying the recognition of bad news. Second, we illustrate that firms in high social capital regions are more likely to recruit senior executives with higher asymmetric earnings timeliness coefficients. This result implies a preference for managers who adopt more conservative accounting practices. We find similar results using an international sample of firms from 21 countries. Our findings offer new insights into how local social norms influence corporate financial reporting.

Individualism and the Formation of Human Capital

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.

When Protecting Children Hits the Bottom Line: Evidence From SDG2000 Firms
Wiebke Szymczak
Scandinavian Journal of Management,
Vol. 42 (2),
2026
Abstract
Intergenerational justice is a core principle of sustainability, yet empirical metrics on the impact of business on future generations remain scarce. Moreover, evidence suggests that different ESG scores capture distinct dimensions of corporate responsibility, highlighting the need for more targeted assessments. This study examines the relationship between corporate engagement with children’s rights and financial performance using a dataset of 1672 firm-year observations, combining a novel children’s rights benchmark with Refinitiv’s financial and sustainability metrics. Results indicate a negative association between marketplace ratings, assessing firms’ child welfare considerations in marketing, and accounting-based profitability, even when controlling for ESG subscores. However, no similar relationship emerges in stock market performance. These findings highlight potential tensions between corporate responsibility and short-term financial outcomes, emphasizing the role of regulatory frameworks and stakeholder engagement in balancing financial and social objectives.

Slight upturn on the horizon, structural problems remain
As the year draws to a close, it remains uncertain whether the German economy is on a path to recovery, as export weakness persisted through the autumn. Nevertheless, a slight upturn is forecast for 2026, supported by fiscal stimulus and rising real incomes. According to the winter forecast of the Halle Institute for Economic Research (IWH), output is projected to grow by 1.0% in 2026, after an increase of just 0.2% in 2025. In September, the IWH economists had predicted growth of 0.8% for 2026 and 0.2% for the current year. According to this forecast, the pace of expansion in East Germany is expected to be slightly slower, mainly due to demographic factors.

Reassessing EU Comparative Advantage: The Role of Technology
Filippo di Mauro, Marco Matani, Gianmarco Ottaviano
International Economics,
Vol. 183,
2025
Abstract
Based on a sufficient statistics approach, we show how the state of technology of European industries relative to the rest of the world can be empirically assessed in a way that is simple in terms of computation, parsimonious in terms of data requirements, but still comprehensive in terms of information. The lack of systematic cross-industry correlation between export specialization and technological advantage suggests that standard measures of revealed comparative advantage only imperfectly capture a country’s technological prowess due to the concurrent influences of factor prices, market size, markups, firm selection and market share reallocation. These findings offer policy insights relevant to the EU’s external competitiveness debate, echoing several recommendations from the Draghi report. Achieving export specialization in key sectors requires more than just technological superiority.

Management Opposition, Strikes and Union Threat
Patrick Nüß
IWH Discussion Papers,
No. 17,
2025
Abstract
I estimate management opposition to unions in terms of hiring discrimination in the German labor market. By sending 13,000 fictitious job applications, revealing union membership in the CV and pro-union sentiment via social media accounts, I provide evidence for hiring discrimination against union supporters. Callback rates are on average 15% lower for union members. Discrimination is strongest in the presence of a high sectoral share of union members and large firm size. I further explore variation in regional and sectoral strike intensity over time and find suggestive evidence that discrimination increases if a sector is exposed to an intense strike. Discrimination is positively associated with the sectoral share of firms that voluntarily orientate wages to collective agreements. These results indicate that hiring discrimination can be explained by union threat effects.

Climate Change Economics in Vietnam: Redefining Economic Impact
Christian Otto, Christoph Schult, Thomas Vogt
Abstract
Vietnam, a lower-middle-income economy, faces severe climate risks from heat waves, sea-level rise, and tropical cyclones, which are expected to intensify under ongoing global warming. Using a dynamic general equilibrium model, we analyze economic transition dynamics from 2015 to 2100, incorporating heat-induced labor productivity losses, agricultural land loss, and cyclone-related property damage. We compare a Paris-compatible scenario limiting warming to below 2 °C with a high-emission scenario reaching 4–5 °C. While output and investment impacts remain highly uncertain and statistically indistinguishable across scenarios until 2100, consumption losses are significantly larger under high emissions, mainly driven by heat-related productivity declines, with cyclones contributing most to uncertainty. These findings underscore the importance of considering multiple impact channels beyond output damages in climate-development research.

Trade Policy Sensitivity and Global Stock Returns: Evidence From the 2016 U.S. Presidential Election
Dien Giau Bui, Iftekhar Hasan, Chih-Yung Lin, Ngoc Thuy Mai, Chris Vaike
Journal of Banking and Finance,
Vol. 178 (September),

Abstract
This paper introduces a novel measure to quantify firms’ sensitivity to shifts in bilateral trade flows between the United States and its trading partners. We exploit the 2016 U.S. presidential election as an exogenous shock to trade policy expectations and assess the stock market reactions of firms across 52 countries. Our findings indicate that firms with higher trade policy sensitivity experienced significantly more negative stock returns surrounding the election. These results are robust to variations in event windows, return model specifications, and alternative estimations of trade policy sensitivity.

Recovery on shaky ground – tariffs dampen growth, but a change in fiscal policy is on the way
In late summer 2025, it is still unclear whether the German economy is on the road to recovery, as it has to cope with the dampening effect of higher US tariffs in the second half of the year. It is not until 2026 that fiscal policy stimulus measures, combined with low key interest rates, will probably lead to an economic upturn. According to the autumn forecast of the Halle Institute for Economic Research (IWH), production is then expected to increase by 0.8%, following 0.2% in 2025. Similar rates of expansion are also expected for East Germany. In June, the IWH economists were forecasting growth of 1.1% for 2026 and 0.4% for the current year.
