Fostering Export Diversification in Niger: Niger
Rasmané Ouedraogo
and
Tomohide Mineyama
This selected issue paper investigates the drivers of diversification and explores the potential for fostering diversification in Niger with a focus on horizontal policies. The empirical results from panel regressions indicate that reforms to enhance human capital and the quality of infrastructure, to promote digitalization, to remove barriers to trade and improve governance are likely to yield the largest gains in terms of diversification for Niger.

Drivers of Inflation: Hungary
Estefania Cohn-Bech
,
Karim Foda
, and
Agustin Roitman
Though high and rising inflation has been a challenge for most economies across Europe in 2022 and into 2023, it has accelerated in Hungary to the highest level in Europe. This paper examines how and why Hungary reached historically high inflation. It draws on an augmented Phillips Curve to estimate the impact of common drivers of inflation, examines the role of labor market tightness and policy stances, and analyzes possible changes to the degree of exchange rate pass-through in recent years. Overall, a rapid recovery from the COVID-19 crisis, a series of exogenous shocks, and too loose a policy mix fueled inflation to its highest level in decades. Though monetary and fiscal policies are now tightening, regulatory price caps undermine those efforts. Going forward, a consistently and persistently tight overall policy mix is needed to drive inflation back to the central bank’s target.

Hungarian Monetary Policy Operations Before, During, and After the Pandemic: Hungary
Mr. Tonny Lybek
Within its inflation-targeting framework, the Magyar Nemzeti Bank (MNB) has frequently adjusted its monetary operations. This has raised questions about their internal consistency, appropriateness, and effectiveness. A broader assessment, implying a comparison to a counterfactual, is outside the scope of this paper. Our prior is agnostic. We find that the changes were generally well-motivated within the MNB statutory powers; prioritized, transparently explained, and monitored; and promptly adjusted, when they no longer served their purpose. Occasionally, some tools have worked at cross purposes. Government policies have at times hampered monetary policy. Simplicity comes with a premium, as complexity can blur signals.

Surrogate Data Models: Interpreting Large-scale Machine Learning Crisis Prediction Models

Machine learning models are becoming increasingly important in the prediction of economic crises. The models, however, use datasets comprising a large number of predictors (features) which impairs model interpretability and their ability to provide adequate guidance in the design of crisis prevention and mitigation policies. This paper introduces surrogate data models as dimensionality reduction tools in large-scale crisis prediction models. The appropriateness of this approach is assessed by their application to large-scale crisis prediction models developed at the IMF. The results are consistent with economic intuition and validate the use of surrogates as interpretability tools.

Assessing the Impact of Supply Disruptions on the Global Pandemic Recovery
Harri Kemp
,
Mr. Rafael A Portillo
, and
Marika Santoro
We estimate the role of (pre-Ukraine war) supply disruptions in constraining the Covid-19 pandemic recovery, for several advanced economies and emerging markets, and globally. We rely on two approaches. In the first approach, we use sign-restricted Vector Auto Regressions (SVAR) to identify supply and demand shocks in manufacturing, based on the co-movement of surveys on new orders and suppliers’ delivery times. The effects of these shocks on industrial production and GDP are recovered through a combination of local projection methods and the input-output framework in Acemoglu et al. (2016). In the second approach, we use the IMF’s G20 model to gauge the importance of supply shocks in jointly driving activity and inflation surprises. We find that supply disruptions subtracted between 0.5 and 1.2 percent from global value added during the global recovery in 2021, while also adding about 1 percent to global core inflation that same year.

AI and Macroeconomic Modeling: Deep Reinforcement Learning in an RBC model
Tohid Atashbar
and
Rui Aruhan Shi
This study seeks to construct a basic reinforcement learning-based AI-macroeconomic simulator. We use a deep RL (DRL) approach (DDPG) in an RBC macroeconomic model. We set up two learning scenarios, one of which is deterministic without the technological shock and the other is stochastic. The objective of the deterministic environment is to compare the learning agent's behavior to a deterministic steady-state scenario. We demonstrate that in both deterministic and stochastic scenarios, the agent's choices are close to their optimal value. We also present cases of unstable learning behaviours. This AI-macro model may be enhanced in future research by adding additional variables or sectors to the model or by incorporating different DRL algorithms.

Weighted Median Inflation Around the World: A Measure of Core Inflation
Laurence M. Ball
,
Carlos Carvalho
,
Christopher Evans
, and
Mr. Luca A Ricci
The standard measure of core or underlying inflation is the inflation rate excluding food and energy prices. This paper constructs an alternative measure, the weighted median inflation rate, for 38 advanced and emerging economies using subclass level disaggretion of the CPI over 1990-2021, and compares the properties of this measure to those of standard core. For quarterly data, we find that the weighted median is less volatile than standard core, more closely related to economic slack, and more closely related to headline inflation over the next year. The weighted median also has a drawback: in most countries, it has a lower average level than headline inflation. We therefore also consider a measure of core inflation that eliminates this bias, which is based on the percentile of sectoral inflation rates that matches the sample average of headline CPI inflation.

Guaranteeing Trade in a Severe Crisis: Cash Collateral over Bank Guarantees
Antonis Kotidis
,
Ms. Margaux MacDonald
, and
Dimitris Malliaropulos
Banks guarantee international trade through letters of credit. This paper analyzes what happens to trade when the critical role of banks as trade guarantors is compromised. Using the case of the Greek capital controls in 2015, the events around which led to a massive loss of confidence in the domestic banking system, we show that firms whose operations were more dependent on domestic banks suffered a steep decline in imports and, subsequently, exports. This operated through letters of credit, which during the capital controls period had to be backed by firms’ own cash collateral rather than the bank guarantee. As a result, cash-poor firms imported relatively less. Public intervention to guarantee transactions is shown to help mitigate some of the decline in imports.

Global Supply Chain Disruptions: Challenges for Inflation and Monetary Policy in Sub-Saharan Africa
Zo Andriantomanga
,
Marijn A. Bolhuis
, and
Shushanik Hakobyan
The Covid-19 pandemic has led to a large disruption of global supply chains. This paper studies the implications of supply chain disruptions for inflation and monetary policy in sub-Saharan Africa. Increases in supply chain pressures have had a sizeable impact on headline, food, and tradable inflation for a panel of 29 sub-Saharan African countries from 2000 to 2022. Our findings suggest that central banks can stabilize inflation and output more efficiently by monitoring global supply chains and adjusting the monetary policy stance before the disruptions have fully passed through into all inflation components. The gains from monitoring supply chain disruptions are particularly large for open economies which tend to experience outsized second-round effects on the prices of non-tradable goods and services.

Differential Effects of Macroprudential Policy
Nina Biljanovska
and
Sophia Chen
We explore the differential effects of lender-based macroprudential policies on new mortgage borrowing for households of different income using a comprehensive dataset that links macroprudential policy actions with household survey data for European Union countries. The main results suggest that higher-income households on average experience a larger reduction in mortgage loan size than lower-income households when regulation targeting total lenders’ assets tightens. In contrast, lower-income households on average experience a larger reduction in mortgage loan size than higher-income households when regulation targeting lenders’ capital requirements tightens. We also provide evidence of the different channels through which the differential effects operate.
