Has the Transmission of US Monetary Policy Changed Since 2022?
Description: Activity and inflation responded slowly to the Federal Reserve’s rate hikes in 2022. Was this because the transmission of monetary policy had changed? Or did other shocks offset tighter policy? We use pre-pandemic data to estimate a VAR with monetary policy shocks identified from high-frequency data, and use it as a filter to back out the sequence of monetary policy shocks consistent with data since 2022. We compare these implied shocks to the actual shocks and find the difference statistically significant during February-July 2022. These differences imply that monetary transmission was around 25 percent weaker than normal. Our method accounts for other shocks; allowing them to change to match the post-COVID covariance of the data produces similar results but in a shorter period. We decompose changes in the uncertainty of our estimate and find that colinearity of shocks is generally more important than uncertainty over model parameters. We extend our analysis to central bank information shocks and find Federal Reserve communication was less powerful than usual during 2021.

Escaping the Financial Dollarization Trap: The Role of Foreign Exchange Intervention
Description: Financial dollarization is considered a source of macroeconomic instability in many emerging economies. Dollarization constrains the ability of central banks to stimulate output during economic downturns. In contrast to the conventional monetary transmission mechanism, a monetary policy loosening in a dollarized economy leads to a currency depreciation, adverse balance sheet effects, and a contraction in investment and output growth. In this paper we evaluate the role of foreign exchange reserves in facilitating macroeconomic stabilization in a financially dollarized economy. We first show empirically that foreign exchange intervention in response to capital outflows can largely reduce the volatility of output and the real exchange rate in dollarized economies. We then develop a small open economy model with foreign currency debt and balance sheets effects. Our quantitative model shows that an active foreign exchange intervention policy is sufficient for offsetting the output volatility associated with financial dollarization. These results can explain the prevalence of low macroeconomic volatility in some dollarized economies (Christiano et al., 2021) and they highlight the role of foreign exchange reserves in reducing the welfare costs of dollarization.

A Projection Model for Resource-rich and Dollarized Economy: The Democratic Republic of the Congo
Description: The paper introduces a semi-structural Quarterly Projection Model (QPM) tailored for the Democratic Republic of the Congo (DRC), highlighting its resource richness and high degree of dollarization. We provide an overview of the model's specifications to elucidate key features of the DRC economy and present its properties, evaluating its alignment with DRC data and assessing its goodness of fit. Additionally, the paper demonstrates the QPM's practical application through a counterfactual scenario, comparing policy recommendations with the actual policy responses of the Central Bank of the Republic of Congo to observed exchange rate and inflation pressures in 2023. Beyond the QPM, the paper showcases supplementary tools that enhance its utility for generating medium-term forecasts and developiong narratives in support of monetary policymaking. Specifically, we introduce the Nowcasting and Near-Term Forecast models, designed to assess the economy in real-time and predict short-term inflationary trends.

A Conceptual Policy Framework for Leveraging Digitalization to Support Diversification in Sub-Saharan Africa
Description: The need for Sub-Saharan African (SSA) countries to diversify their economies is more urgent than ever. However, despite its established economic benefits, several challenges have precluded diversification in SSA. Against this backdrop, interesting initiatives to further adopt digital technologies, particularly during the COVID-19 pandemic, suggest that digitalization is a promising avenue to overcome barriers to diversification. Fast-paced advances in the diffusion of digital technologies and knowledge have the potential to transform SSA economies through several channels. By connecting people and facilitating the rapid diffusion of information, digitalization also promises to reshape the industrial structure of activities in new and unprecedented ways. Therefore, digitalization has the potential to promote diversification and growth in SSA by acting both as an enabler and driver of economic activities, helping support resilience. Yet, while the empirical literature on SSA suggests that digitalization can provide new opportunities for growth, employment, productivity, and inclusion, the impact on diversification has not been studied. This paper aims to fill this important gap in the literature. It also aims to strengthen IMF engagement with SSA policy makers by providing a conceptual policy framework, encompassing both horizontal and sectoral policies, on how to leverage digitalization to support diversification and boost resilience in a post-COVID world.

A Tale of Two Margins: Monetary Policy and Capital Misallocation
Description: This paper investigates the impact of monetary policy on capital misallocation, focusing on its heterogeneous effects on firms. Using Spanish firm-level data spanning 1999 to 2019, we demonstrate that expansionary monetary policy leads to a reduction in capital misallocation, measured by the within-industry dispersion of firms’ marginal revenue product of capital (MRPK). To analyze the underlying mechanism, we first examine the intensive margin and find that high-MRPK firms exhibit a greater increase in investment and debt financing relative to low-MRPK firms following a monetary policy easing surprise. We also find that a firm’s MRPK serves as a stronger determinant of its investment sensitivity to monetary policy than factors such as age, leverage, or cash, suggesting that MRPK is a reliable proxy for financial frictions. Next, we explore the extensive margin and demonstrate that monetary policy easing stimulates entry and discourages exit, although the quantitative impact is small. Moreover, we find no significant changes in the composition of high- and low-MRPK entrants or exiters. Overall, our findings suggest that expansionary monetary policy primarily reduces capital misallocation by alleviating financial frictions among incumbent productive and constrained firms.

Sovereign Green Bonds: A Catalyst for Sustainable Debt Market Development?
Description: In traditional bond markets, sovereign bonds provide benchmarks and serve as catalysts for the corporate bond market development. Contrary to the usual sequence of bond market development, sovereign issuers are latecomers to sustainable bond markets. Yet, our empirical study finds that sovereign green bond issuance can have quantitative and qualitative benefits for the development of private sustainable bond markets. Our results suggest that both the number and the size of corporate green bond issuance increase more in a jurisdiction after the sovereign debut. The results are more pronounced in countries with stronger climate policies. Sovereign green bond issuance also improves the quality of green verification standards in the corporate bond market more generally, consistent with the aim of fostering third-party reviews and promoting best practice in green reporting and verification. Finally, our work provides evidence that the sovereign debut increases liquidity and diminishes yield spreads of corporate green bonds in the same jurisdiction.

Cross-Border Payments Integration in Latin America and the Caribbean
Description: Cross-border payment inefficiencies are a significant barrier to trade both within Latin America and the Caribbean (LAC) and between LAC and other regions. This paper provides a comprehensive review of historical efforts undertaken by various countries within the LAC region to address these challenges. We also explore the potential of recent financial innovations, such as digital currencies and blockchain technology, to enhance cross-border payments. While new technologies do not substitute for prudent and credible macroeconomic policies, leveraging these technologies can help LAC countries reduce transaction costs and times, thus enhancing economic efficiency and fostering deeper regional and global trade relationships.

Aging Gracefully: Steering the Banking Sector through Demographic Shifts
Description: We analyze how aging populations might affect the stability of banking systems through changes in the balance sheets and risk preferences of banks over the period 2000-2022. While the anticipated decline in maturity transformation due to aging hints at a possible reduction in risk exposure, an older population may propel banks towards yield-seeking behaviors, offsetting the diminishing prominence of conventional lending operations. Through a comprehensive examination of advanced economies over the past two decades, our findings reveal a general enhancement in bank stability correlating with the aging of populations. However, the adaptive responses of banks to these demographic changes are potentially introducing tail risks. Given the rapid global shift towards aging societies, our analysis highlights the critical need for policymakers to be proactive and vigilant. This is particularly pertinent considering historical precedents where periods of relative stability have often been harbingers of emerging risks.

Inequality in a More Equal World—Labor Market Gender Gaps in St. Lucia
Description: St. Lucia has enviably high female labor force participation rate and strikingly low participation gap vis-à-vis male. The latter is lower than OECD average and way below world average. Women are also more educated than men. Yet, using a micro dataset of St. Lucia Labor Force Survey over the period 2016-2021, our analysis points towards disproportionate effects of childcare on female participation and unemployment and a substantial gender gap in labor income for workers without higher education. Moreover, the income gap is not explained by observable worker characteristics. While the paper does not explore causal links, this unique feature of high female participation and, yet, considerable gender gaps in other dimensions could be due to the social, historical, and political structure that resulted in a matrifocal but not a matriarchal system. At the same time, the small gender gaps for workers with higher education across participation, unemployment, and labor income seem to suggest that women can overcome some barriers through education. Our results bring to the fore two crucial aspects related to gender studies: (i) While macroeconomic indicators like female labor participation rate are important tools, they are not always sufficient to capture progress in gender equality; and (ii) econometric analysis needs to be complemented with a more holistic understanding of the history and social context shaping deeply rooted gender traits.

Reinforcement Learning from Experience Feedback: Application to Economic Policy
Description: Learning from the past is critical for shaping the future, especially when it comes to economic policymaking. Building upon the current methods in the application of Reinforcement Learning (RL) to the large language models (LLMs), this paper introduces Reinforcement Learning from Experience Feedback (RLXF), a procedure that tunes LLMs based on lessons from past experiences. RLXF integrates historical experiences into LLM training in two key ways - by training reward models on historical data, and by using that knowledge to fine-tune the LLMs. As a case study, we applied RLXF to tune an LLM using the IMF's MONA database to generate historically-grounded policy suggestions. The results demonstrate RLXF's potential to equip generative AI with a nuanced perspective informed by previous experiences. Overall, it seems RLXF could enable more informed applications of LLMs for economic policy, but this approach is not without the potential risks and limitations of relying heavily on historical data, as it may perpetuate biases and outdated assumptions.
