Shocked: Electricity Price Volatility Spillovers in Europe
Serhan Cevik
and
Yueshu Zhao
European electricity markets are in the midst of unprecedented changes—caused by Russia’s invasion of Ukraine and the rise of renewable sources of energy. Using high-frequency data, this paper investigates volatility spillovers across 24 countries in the European Union (EU) during the period 2014–2024 to provide a better understanding of the transmission of risks in an international context. We develop both a static and a dynamic assessment of spillover effects and directional decomposition between individual countries. Our main findings show that about 73 percent of the forecast error variation is explained by cross-variance shares, which means only 27 percent can be attributed to shocks within each country. In other words, cross-border volatility spillovers dominate the behavior in national electricity markets in Europe—and this effect has grown over time. We also implement an augmented gravity model of bilateral volatility spillovers across power markets in the EU. Altogether, these results provide important insights to policymakers and regulators with regards to greater integration of electricity markets and infrastructure improvements that would also help with the transition to low-carbon sources of power generation and strengthen energy security in Europe.

The Heterogeneous Effects of Uncertainty on Trade

Sampawende J Tapsoba
This paper empirically investigates the relationship between uncertainty and trade. We use a gravity model for 143 countries over the 1980-2021 period to assess the impact of uncertainty on bilateral trade. We confirm that, in general, uncertainty has a negative impact on trade. The findings suggest that a one standard deviation increase in global uncertainty is associated with a decline in bilateral trade by 4.5 percent, with fuel and industrial products trade being the most impacted. This negative impact is observed for uncertainty on both sides of the border, with a higher impact of uncertainty from the importing country. The article goes deeper into the analysis and shows that deeper trade integration (horizontal integration) mitigates the negative impact of uncertainty on trade. In contrast, higher participation in global value chains (vertical integration) amplifies the negative effect of uncertainty on trade. We find that geopolitical tensions amplify the deterrent effect of uncertainty on trade. Finally, the result is heterogeneous across income levels, regions, and resource endowment: (a) uncertainty has a negative impact on bilateral trade between Emerging Markets and Developing Economies and Advanced Economies; however, (b) at the regional level, Africa and Europe’s intraregional trade decrease as uncertainty surges. (c) Evidence shows that non-resources-rich countries are more at risk.

Changing Global Linkages: A New Cold War?
Gita Gopinath
,
Pierre-Olivier Gourinchas
,
Andrea F Presbitero
, and
Petia Topalova
Global linkages are changing amidst elevated geopolitical tensions and a surge in policies directed at increasing supply chain resilience and national security. Using granular bilateral data, this paper provides new evidence of trade and investment fragmentation along geopolitical lines since Russia’s invasion of Ukraine, and compares it to the historical experience of the early years of the Cold War. Gravity model estimates point to significant declines in trade and FDI flows between countries in geopolitically distant blocs since the onset of the war in Ukraine, relative to flows between countries in the same bloc (roughly 12% and 20%, respectively). While the extent of fragmentation is still relatively small and we do not know how longlasting it will be, the decoupling between the rival geopolitical blocs during the Cold War suggests it could worsen considerably should geopolitical tensions persist and trade restrictive policies intensify. Different from the early years of the Cold War, a set of nonaligned ‘connector’ countries are rapidly gaining importance and serving as a bridge between blocs. The emergence of connectors has likely brought resilience to global trade and activity, but does not necessarily increase diversification, strengthen supply chains, or lessen strategic dependence.

The Market Price of Risk and Macro-Financial Dynamics
Mr. Tobias Adrian
,
Fernando Duarte
, and
Tara Iyer
We propose the conditional volatility of GDP spanned by financial factors as a “Volatility Financial Conditions Index” (VFCI) and show it is closely tied to the market price of risk. The VFCI exhibits superior explanatory power for stock and bond risk premia compared to other FCIs. We use a variety of identification strategies and instruments to demonstrate robust causal relationships between the VFCI and macroeconomic aggregates: a tightening of financial conditions as measured by the VFCI leads to a persistent contraction of output and triggers an immediate easing of monetary policy. Conversely, contractionary monetary policy shocks cause tighter financial conditions.

Financial Shock Transmission to Heterogeneous Firms: The Earnings-Based Borrowing Constraint Channel
Livia Chiţu
,
Magdalena Grothe
,
Tatjana Schulze
, and
Ine Van Robays
We study the heterogeneous impact of jointly identified monetary policy and global risk shocks on corporate funding costs. We disentangle these two shocks in a structural Bayesian Vector Autoregression framework and investigate their respective effects on funding costs of heterogeneous firms using micro-data for the US. We tease out mechanisms underlying the effects by contrasting traditional financial frictions arising from asset-based collateral constraints with the recent earnings-based borrowing constraint hypothesis, differentiating firms across leverage and earnings. Our empirical evidence strongly supports the earnings-based borrowing constraint hypothesis. We find that global risk shocks have stronger and more heterogeneous effects on corporate funding costs which depend on firms' position within the earnings distribution.

Food Prices and Political Instability
Mr. Rabah Arezki
and
Markus Bruckner
We examine the effects that variations in the international food prices have on democracy and intra-state conflict using panel data for over 120 countries during the period 1970-2007. Our main finding is that in Low Income Countries increases in the international food prices lead to a significant deterioration of democratic institutions and a significant increase in the incidence of anti-government demonstrations, riots, and civil conflict. In the High Income Countries variations in the international food prices have no significant effects on democratic institutions and measures of intra-state conflict. Our empirical results point to a significant externality of variations in international food prices on Low Income Countries' social and political stability.

Opening Up and Geographic Diversification of Trade in Transition Economies
Mr. Oleh Havrylyshyn
and
Mr. Hassan Al-Atrash
This paper looks at the progress in transition and the geographic diversification of trade, focusing on two issues--the degree of trade openness and trade integration--for a sample of countries in transition. It concludes that about half of the group of countries sampled are becoming as open as similar market economies, but that many others remain relatively closed. Geographic diversification (to the European Union) is found to be greater the closer is geographic proximity and the more advanced the country is with reforms. The analysis is then extended, in an illustrative way, to show how much larger would be the share of exports to the EU if structural reforms were more ambitious.
