Abstract
In a multi-sector and multi-region framework, this paper employs a dynamic general equilibrium model to analyze climate-resilient economic development (DGE-CRED) in Vietnam. We calibrate sector and region-specific damage functions and quantify climate variable impacts on productivity and capital formation for various shared socioeconomic pathways (SSPs 119, 245, and 585). Our results based on simulations and cost-benefit analyses reveal a projected 5 percent reduction in annual GDP by 2050 in the SSP 245 scenario. Adaptation measures for the dyke system are crucial to mitigate the consumption gap, but they alone cannot sufficiently address it. Climate-induced damages to agriculture and labor productivity are the primary drivers of consumption reductions, underscoring the need for focused adaptation measures in the agricultural sector and strategies to reduce labor intensity as vital policy considerations for Vietnam’s response to climate change.

A Multi-Model Assessment of Inequality and Climate Change
Marie Young-Brun, et al.
Nature Climate Change,
October
2024
Abstract
Climate change and inequality are critical and interrelated defining issues for this century. Despite growing empirical evidence on the economic incidence of climate policies and impacts, mainstream model-based assessments are often silent on the interplay between climate change and economic inequality. For example, all the major model comparisons reviewed in IPCC neglect within-country inequalities. Here we fill this gap by presenting a model ensemble of eight large-scale Integrated Assessment Models belonging to different model paradigms and featuring economic heterogeneity. We study the distributional implications of Paris-aligned climate target of 1.5 degree and include different carbon revenue redistribution schemes. Moreover, we account for the economic inequalities resulting from residual and avoided climate impacts. We find that price-based climate policies without compensatory measures increase economic inequality in most countries and across models. However, revenue redistribution through equal per-capita transfers can offset this effect, leading to on average decrease in the Gini index by almost two points. When climate benefits are included, inequality is further reduced, but only in the long term. Around mid-century, the combination of dried-up carbon revenues and yet limited climate benefits leads to higher inequality under the Paris target than in the Reference scenario, indicating the need for further policy measures in the medium term.

Abstract
The German economy has stagnated for over two years, with a slow recovery anticipated in the coming quarters. However, growth is unlikely to reach pre-COVID-19 levels anytime soon. Decarbonisation, digitisation, demographic changes, and heightened competition from China are dampening growth prospects. GDP is projected to decline by 0.1 % in 2024, with increases of 0.8 % and 1.3 % in the subsequent years. Rising private consumption and improving foreign trade are expected to contribute positively to the economic upturn in Germany. Economic policy should prioritise reducing productivity barriers, facilitating structural changes, and lowering political uncertainty to support recovery.

Joint Economic Forecast 2/2024: German economy in transition ‒ weak momentum, low potential growth
The Joint Economic Forecast Project Group forecasts a 0.1% decline in Germany's gross domestic product in 2024. Looking further ahead, the institutes expect a weak recovery with growth of 0.8% (2025) and 1.3% (2026). Compared to the spring forecast, this represents a down-ward revision of 0.2 (2024) and 0.6 (2025) percentage points. “In addition to the economic downturn, the German economy is also being weighed down by structural change,” says Dr Geraldine Dany-Knedlik, head of Forecasting and Economic Policy at the German Institute for Economic Research (DIW Berlin). “Decarbonisation, digitalisation, and demographic change – alongside stronger competition with companies from China – have triggered structural adjustment processes that are dampening the long-term growth prospects of the German economy.”

Deutsche Wirtschaft im Umbruch – Konjunktur und Wachstum schwach
Dienstleistungsauftrag des Bundesministeriums für Wirtschaft und Klimaschutz,
No. 2,
2024
Abstract
Die deutsche Wirtschaft tritt seit über zwei Jahren auf der Stelle. In den kommenden Quartalen dürfte eine langsame Erholung einsetzen. Aber an den Trend von vor der COVID-19-Pandemie wird das Wirtschaftswachstum auf absehbare Zeit nicht mehr anknüpfen können. Die Dekarbonisierung, die Digitalisierung, der demografische Wandel und wohl auch der stärkere Wettbewerb mit Unternehmen aus China haben strukturelle Anpassungsprozesse in Deutschland ausgelöst, die die Wachstumsaussichten für die deutsche Wirtschaft dämpfen.
Das Bruttoinlandsprodukt dürfte im Jahr 2024 um 0,1% sinken und in den kommenden beiden Jahren um 0,8% bzw. 1,3% zunehmen. Damit revidieren die Institute ihre Prognose vom Frühjahr 2024 leicht nach unten. Getragen wird die schmalspurige Erholung vom steigenden privaten Verbrauch, der von kräftigen Zuwächsen der real verfügbaren Einkommen angeregt wird. Das Anziehen der Konjunktur in wichtigen Absatzmärkten, wie den europäischen Nachbarländern, wird den deutschen Außenhandel stützen. Zusammen mit günstigeren Finanzierungsbedingungen kommt dies den Anlageinvestitionen zugute. Die Wirtschaftspolitik sollte Produktivitätshemmnisse abbauen, den Strukturwandel zulassen und die politische Unsicherheit verringern.

Konjunktur aktuell: Deutschland in der Stagnation festgefahren – privater Konsum weiter unter dem Niveau
von vor der Pandemie
Konjunktur aktuell,
No. 1,
2024
Abstract
Zu Beginn des Jahres 2024 zeigen Stimmungsindikatoren etwas aufgehellte Aussichten für die internationale Konjunktur. In Europa dürfte die Dynamik allerdings recht schwach bleiben. Deutschland befindet sich in einer lang anhaltenden Stagnation, die sich bis zum Sommer fortsetzen wird. Für die Zeit danach ist mit einem leichten Anziehen der Konjunktur zu rechnen. Das Bruttoinlandsprodukt dürfte im Jahr 2024 um lediglich 0,2% expandieren, für 2025 prognostiziert das IWH einen Zuwachs um 1,5%.

Flight to Safety: How Economic Downturns Affect Talent Flows to Startups

Review of Financial Studies,
No. 3,
2024
Abstract
Using proprietary data from AngelList Talent, we study how startup job seekers’ search and application behavior changed during the COVID-19 downturn. We find that workers shifted their searches and applications away from less-established startups and toward more-established ones, even within the same individual over time. At the firm level, this shift was not offset by an influx of new job seekers. Less-established startups experienced a relative decline in the quantity and quality of applications, ultimately affecting their hiring. Our findings uncover a flight-to-safety channel in the labor market that may amplify the procyclical nature of entrepreneurial activities.

Macroeconomic Effects from Sovereign Risk vs. Knightian Uncertainty

IWH Discussion Papers,
No. 27,
2023
Abstract
This paper compares macroeconomic effects of Knightian uncertainty and risk using policy shocks for the case of Italy. Drawing on the ambiguity literature, I use changes in the bid-ask spread and mid-price of government bonds as distinct measures for uncertainty and risk. The identification exploits the quasi-pessimistic behavior under ambiguity-aversion and the dealer market structure of government bond markets, where dealers must quote both sides of the market. If uncertainty increases, ambiguity-averse dealers will quasi-pessimistically quote higher ask and lower bid prices – increasing the bid-ask spread. In contrast, a pure change in risk shifts the risk-compensating discount factor which is well approximated by the change in bond mid-prices. I evaluate economic effects of the two measures within an instrumental variable local projection framework. The main findings are threefold. First, the resulting shock time series for uncertainty and risk are uncorrelated with each other at the intraday level, however, upon aggregation to monthly level the measures become correlated. Second, uncertainty is an important driver of economic aggregates. Third, macroeconomic effects of risk and uncertainty are similar, except for the response of prices. While sovereign risk raises inflation, uncertainty suppresses price growth – a result which is in line with increased price rigidity under ambiguity.

No. 18640,
2023
Abstract
While access to high-quality microdata is essential for economic research and policy evaluation, effective access to such data remains limited in Europe. It varies from country to country, with uneven information on access procedures. This is a major obstacle to social science research, including research on European competitiveness and the effects of climate change, inequality, globalization, and digitalization. The objective of this paper, which is based on a brainstorming exercise coordinated by CEPR and CompNet, is to assess the status quo and discuss a series of proposals for improving access to Microdata for economic research. We underline the need for developing the relevant tools for extended access to and use of European business statistics microdata. Building such tools entails both establishing the requested microdata and creating a body facilitating cross-country access to the established databases with harmonized content.
