This paper investigates the relationship between heterogeneity in sectoral price stickiness and the response of the economy to aggregate real shocks. We show that sectoral heterogeneity reduces inflation persistence for a constant average duration of price spells, and that inflation persistence can fall despite duration increases associated with increases in heterogeneity. We also find that sectoral heterogeneity reduces the persistence and volatility of interest rate and output gap for a constant price spells duration, while the qualitative impact on inflation volatility tends to be positive. A relevant policy implication is that neglecting price stickiness heterogeneity can impair the economic dynamics assessment.

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.

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.

Die deutsche Wirtschaft steht unter Druck, doch die aktuellen Maßnahmen der Regierung führen kaum zu einer nachhaltigen Erholung. Unternehmen sind mit Unsicherheiten konfrontiert, die Investitionen hemmen – insbesondere hinsichtlich der Energieversorgung und der damit verbundenen Kosten. Viele Betriebe schieben deshalb notwendige Investitionen auf – genau die Investitionen, die das wirtschaftliche Wachstum antreiben könnten.

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.

This study employs bilateral data on external assets to examine the impact of climate policies on the reallocation of international capital. We find that the stringency of climate policy in the destination country is significantly and positively associated with an increase in the allocation of portfolio equity and banking investment to that country. However, it does not show significant effects on the allocation of foreign direct investment and portfolio debt. Our findings are not driven by valuation effects, and we present evidence that suggests diversification, suasion, and uncertainty mitigation as possible underlying mechanisms.

Gegenstand dieses Evaluationsberichts ist die Replikation und Erweiterung der Ergebnisse des vorhergehenden Gutachtens zur Evaluation der Gemeinschaftsaufgabe ‚Verbesserung der regionalen Wirtschaftsstruktur‘ (GRW) 

Der vorliegende Evaluationsbericht verfolgt zwei Ziele. Erstens aktualisiert er die Ergebnisse aus dem vorherigen Gutachten. Zweitens betrachtet er einige Aspekte zu den Wirkungen der GRW-Förderung vertiefend. Dazu gehört insbesondere die Frage, ob die GRW für die geförderten Betriebe tatsächlich einen Anreizeffekt im Sinne einer Ausweitung der Investitionstätigkeit hatte und wie sich die Effekte der Förderung unter Verwendung fortgeschrittener Produktivitätsmaße darstellt. Des Weiteren widmet sich der Evaluationsbericht einer vertiefenden Untersuchung heterogener Effekte auf sektoral disaggregierter Ebene sowie nach Betriebsgrößenklassen. Wo es möglich ist, analysiert der Bericht zudem längere Zeiträume nach dem Beginn des Förderprojekts. Schließlich widmet sich der Evaluationsbericht Fragen zur Wirtschaftlichkeit des GRW-Programms auf einzelbetrieblicher Ebene, indem er die Effekte in Beziehung setzt zur Höhe der aufgewendeten Fördermittel. 

Die Aussichten für die internationale Konjunktur bleiben leicht eingetrübt. In Europa setzt sich die zaghafte Erholung fort. In Deutschland vermehren sich die Anzeichen für eine konjunkturelle Besserung. Alles in allem wird die Produktion im Sommerhalbjahr wohl nur verhalten ausgeweitet, doch ab Herbst dürfte die Belebung Fahrt aufnehmen. Das Bruttoinlandsprodukt dürfte im Jahr 2024 um 0,3% expandieren, für 2025 prognostiziert das IWH einen Zuwachs um 1,5%.
