- Abstract
- An increase of e100 per tonne in the EU carbon price reduces the carbon footprint but lowers GDP due to higher energy costs and carbon leakage. Using a dynamic multi-sector, multi-country model augmented with an energy block that includes endogenous renewable energy investment, we analyze the macroeconomic and emissions effects of a carbon price. Investment in renewable energy mitigates electricity price increases in the medium term, leading to a smaller GDP loss (up to -0.4%) and a larger emissions reduction (24%) in the EU. Neglecting renewable energy investment overestimates the negative economic impact. We also find that a Carbon Border Adjustment Mechanism (CBAM) reduces carbon leakage but slightly hurts GDP and inflation as the competitive gain is offset by the higher costs of imported intermediate inputs.

- Abstract
- In light of recent global economic and geopolitical shocks threatening trade openness, this report aims to shed light on geoeconomic fragmentation and develops a rich set of new tools to assess its economic effects and implications for central banks. The report shows that, although global trade integration has largely withstood recent disruptions and the rise of inward-looking policies, selective decoupling between few trading partners (United States vis-à-vis China, western economies vis-à-vis Russia) and for specific products (such as advanced technologies) is occurring. Survey data show that, although European firms are reorganising supply chains critical foreign dependencies persist. A firm-level stress test reveals that sudden disruptions in the supply of critical inputs from high-risk countries would lead to significant, albeit very heterogeneous, economic losses across firms, regions and sectors. Addressing foreign dependencies with broad-based protectionism policies, however, is self-defeating. In an extreme counterfactual scenario involving prohibitive and across-the-board trade barriers between geopolitical blocs, global GDP could decline by up to 9% coupled with an increase in global inflation of 4 percentage points in the first year, with the impact persisting for at least five years. It is conceivable that trade fragmentation will unravel over the course of a number of years, with supply disruptions becoming more frequent and severe than in the past. If this process should ultimately lead to a less interconnected global economy, countries might suffer from increased volatility and price pressures, as shocks cannot be easily diversified away through trade.
