Chasing the Sun and Catching the Wind: Energy Transition and Electricity Prices in Europe

Description: European power markets are in the midst of unprecedented changes, with a record-breaking surge in energy prices.This paper investigates the impact of green power resources on the level and volatility of wholesale electricity prices at a granular level, using monthly observations for a panel of 24 European countries over the period 2014–2021 and alternative estimation methods including a panel quantile regression approach. We find that renewable energy is associated with a significant reduction in wholesale electricity prices in Europe, with an average impact of 0.6 percent for each 1 percentage points increase in renewable share. We also find evidence for a nonlinear effect—that is, higher the share of renewables, the greater its effect on electricity prices. On the other hand, while quantile estimation results are mixed with regards to the impact of renewables on the volatility of electricity prices, we obtain evidence that renewable energy has a negative effect on volatility at the highest quantiles. Overall, our analysis indicates that policy reforms can help accelerate the green transition while minimizing the volatility in electricity prices.

A Quarterly Projection Model for the WAEMU

Description: This study describes a semi-structural New-Keynesian Quarterly Projection Model (QPM) for the WAEMU zone. In the context of a fixed exchange rate regime and relatively tight capital controls, the central bank for the WAEMU monetary union (Banque Centrale des États de l’Afrique de l’Ouest, BCEAO) can exert some influence on the domestic money markets and interest rates. We adjusted the canonical version of a New Keynesian semi-structural Quarterly Projection Model (QPM) to capture that feature and other aspects specific to the BCEAO monetary policy framework, including an implicit foreign exchange reserve target. The model, which is parametrized though and mix of calibration and Bayesian estimation techniques, displays dynamic properties for the main variables in response to various shocks that are in line with theoretical priors and empirical evidence. Medium-term forecasts considering the Covid-19 pandemic produce sensible results when compared with forecast produced by a standard VAR. Moments computed from artificial data generated with the model match well those observed in the data. Overall, the model displays desirable analytical properties and sensible data-matching and forecasting capabilities and could, therefore, be used by the BCEAO to identify relevant shocks, map their propagation into the WAEMU regional economy, and better support its monetary policy decisions.

Raising Armenia’s Export Potential

Description: Raising Armenia’s long-term growth prospects is critical to meet the pressing need for jobs, achieve higher living standards, and arrest emigration. Armenia’s long-term growth prospects have weakened since the global COVID-19 crisis, while recent global and regional the geopolitical developments added new shocks. This paper argues that there is a need to boost the potential of the tradable sector by focusing on products with higher complexity to sustainably increase Armenia’s growth rate. It provides an overview of Armenia’s export performance, analyzes factors and policy valuables that affect export outcomes in terms of volumes and composition, and draws policy implications.

Financial Innovation and Statistical Methodological Guidance—Key Considerations

Description: Financial risks outside of the traditional banking sector can quickly spread throughout financial systems and lead to disruptions in the real economy. A lack of adequately detailed financial sector statistics can obscure buildups of risks from policymakers and hinder their ability to effectively respond once these risks materialize. In response, authorities worldwide, international organizations, including the IMF, and the Group of 20 (G-20), called for financial reforms and launched efforts to gather information on nonbank financial intermediary (NBFI) activities—including the Data Gaps Initiative (DGI) and enhanced Financial Stability Board (FSB) NBFI data collection. While these initiatives represent significant strides to strengthen NBFI’s data collection, there continue to be gaps in the conceptual and methodological guidance in the financial and macroeconomic statistics manuals on which the FSB, DGI, and national authorities rely; gaps that are increasing in light of increased globalization and the financial sector digitalization. This paper proposes conceptual guidance to help bridge existing and emerging gaps.

Scarring and Corporate Debt

Description: This paper estimates the scarring effect of recessions on corporates’ investment and how it is amplified by the level of corporate debt. Our results suggest that the effect of firms’ debt in shaping the response of investment to recessions is statistically significant and economically sizeable, with high debt firms seeing a larger decline in investment than low debt firms. Back-of-the-envelope calculations suggest that firms’ debt accounts for at least 28 percent of the average medium-term decline of investment following a recession. This effect is especially larger for firms that are credit constrained—small and less profitable firms, as well as firms with high share of short-term debt—and that therefore may find it more difficult to rollover or raise new funds to invest in new projects. The results are robust to several checks, including to various sub-samples, alternative measures of recessions and explanatory variables, and a large set of controls.

Digitalization and Resilience

Description: This paper investigates the role of digitialization in improving economic resilience. Using balance sheet data from 24,000 firms in 75 countries, and a difference-in-differences approach, we find that firms in industries that are more digitalized experience lower revenue losses following recessions. Early data since the outbreak of the COVID-19 pandemic suggest an even larger effect during the resulting recessions. These results are robust across a wide range of digitalization measures—such as ICT input and employment shares, robot usage, online sales, intangible assets and digital skills listed on online profiles—and several alternative specifications.

Monetary Policy Communication and Financial Markets in India

Description: Forward-looking monetary policy communication has become a key element of flexible inflation-targeting regimes across advanced and emerging market economies. The Reserve Bank of India’s implementation of a flexible inflation targeting framework since 2016 has been supported by a broad set of communication tools, more recently aided by policy innovations such as forward guidance on policy rates and, asset purchases, increasing the predictability of monetary policy. A review of the recent innovations of monetary policy communications during the initial waves of the pandemic suggests forward guidance likely played a key role in moderating uncertainty and supporting some asset prices. We also find that the relationship between monetary policy surprises and yields for government and corporate securities across all maturities are positive and statistically significant. The results support an important role for monetary policy communication in guiding market expectations about the monetary policy stance, including the likely path of policy interest rates.

Understanding U.S. Inflation During the COVID Era

Description: This paper analyzes the dramatic rise in U.S. inflation since 2020, which we decompose into a rise in core inflation as measured by the weighted median inflation rate and deviations of headline inflation from core. We explain the rise in core with two factors, the tightening of the labor market as captured by the ratio of job vacancies to unemployment, and the pass-through into core from past shocks to headline inflation. The headline shocks themselves are explained largely by increases in energy prices and by supply chain problems as captured by backlogs of orders for goods and services. Looking forward, we simulate the future path of inflation for alternative paths of the unemployment rate, focusing on the projections of Federal Reserve policymakers in which unemployment rises only modestly to 4.4 percent. We find that this unemployment path returns inflation to near the Fed’s target only under optimistic assumptions about both inflation expectations and the Beveridge curve relating the unemployment and vacancy rates. Under less benign assumptions about these factors, the inflation rate remains well above target unless unemployment rises by more than the Fed projects.

How Persistent are Climate-Related Price Shocks? Implications for Monetary Policy

Description: Climate change is likely to lead to more frequent and more severe supply and demand shocks that will present a challenge to monetary policy formulation. The main objective of the paper is to investigate how climate shocks affect consumer prices in a broad range of countries over a long period using local projection methods. It finds that the impact of climate shocks on inflation depends on the type and intensity of shocks, country income level, and monetary policy regime. Specifically, droughts tend to have the highest overall positive impact on inflation, reflecting rising food prices. Interestingly, floods tend to have a dampening impact on inflation, pointing to the predominance of demand shocks in this case. Over the long run, the dominant monetary policy paradigm of flexible inflation targeting faced with supply-induced climate shocks may become increasingly ineffective, especially in LIDCs. More research is needed to find viable alternative monetary policy frameworks.

Digital Money and Central Banks Balance Sheet

Description: Digital money is a logical step in a process of continuous technological advancement in payment systems. In response, central banks are reviewing their conduct of monetary operations in light of the new shape of financial markets and systems. The impact of digital money will depend on the type of money substitution by digital money. The paper straddles several cases where substitution of CiC (currency in circulation), and bank deposits may take place via digital money such as CBDC or other e-money, and how it would impact the central bank balance sheet. Remuneration of CBDC, if aligned to a new objective, could potentially amplify the effect on the interest rate channel of monetary policy.
