Productive Capacities, Economic Vulnerability and Growth Volatility in Sub-Saharan Africa
Description: Sub-Saharan Africa (SSA) countries, like most developing countries, face major challenges to achieve strong, sustainable, and inclusive growth with the view to reduce significantly persistent poverty and inequality. Many of these challenges results from a high level of economic vulnerability due to simultaneous shocks, notably the Covid-19 pandemic, climate change and the multiplicity of armed conflicts. Hence the need to study policies and means of strengthening economic resilience to shocks. This paper analyzes the effects of productive capacities on the volatility of economic growth in SSA countries when faced with significant vulnerability. The study covers the period 2000-2018 for 43 SSA countries. Using Generalized Method of Moments (GMM), the results show that economic vulnerability contributes to growth volatility in SSA. However, this effect varies according to the performance of productive capacities. Countries with high productive capacities have greater opportunities to mitigate the effect of economic vulnerability on growth volatility. Some specific dimensions of productive capacities (Institutions, ICT) seem to matter more than others. The results of this study provide important recommendations to policy makers.

Whose Asset Sales Matter?
Description: Using novel data on bond trading in the UK, we develop a new measure of selling pressure that can be applied to any trader. We identify exogenous selling pressure in a bond using traders’ sales of other, unrelated bonds.The price impact of a sale depends on who is selling: sales by dealers and hedge funds generate significantly larger impacts than equally sized sales by other investors. We rationalise our findings using a model of differentially informed investors. All else equal, our results suggest that more attention should be devoted to risks to financial stability from these impactful sellers.

Managing Foreign Exchange Rate Risk: Capacity Development for Public Debt Managers in Emerging Market and Low-Income Countries
Description: This paper presents some sound practices for foreign-currency risk management in developing countries and outlines instruments for managing sovereign debt portfolio currency exposures. Adoption of a debt management strategy with well-defined targets for foreign exchange risk is a critical element of public debt risk management. To this end, public debt managers often need to face with complex strategic and operational matters related to public debt hedging practices, including the use of derivatives. In this context, we highlight the main institutional challenges in the management of foreign exchange risk in sovereign debt portfolios and discuss the overall implementation of a foreign exchange risk-management strategy.

Public Perceptions of Canada’s Investment Climate
Description: Canada’s muted productivity growth during recent years has sparked concerns about the country’s investment climate. In this study, we develop a new natural language processing (NPL) based indicator, mining the richness of Twitter (now X) accounts to measure trends in the public perceptions of Canada’s investment climate. We find that while the Canadian investment climate appears to be generally favorable, there are signs of slippage in some categories in recent periods, such as with respect to governance and infrastructure. This result is confirmed by both survey-based and NLP-based indicators. We also find that our NLP-based indicators would suggest that perceptions of Canada’s investment climate are similar to perceptions of U.S. investment climate, except with respect to governance, where views of U.S. governance are notably more negative. Comparing our novel indicator relative to traditional survey-based indicators, we find that the NLP-based indicators are statistically significant in helping to predict investment flows, similar to survey-based measures. Meanwhile, the new NLP-based indicator offers insights into the nuances of data, allowing us to identify specific grievances. Finally, we construct a similar indicator for the U.S. and compare trends across countries.

Capital Controls on Outflows: New Evidence and a Theoretical Framework
Description: We study capital controls on outflows (CCOs) in situations of macroeconomic and financial distress. We present novel empirical evidence indicating that CCO implementation is associated with crises and declines in GDP growth. We then develop a theoretical framework that is consistent with such empirical findings and also yields policy and welfare lessons. The theory features costly coordination failures by foreign investors which can sometimes be avoided by suitably tailored CCOs. The benefits of CCOs as coordination devices can make them optimal even if CCOs entail deadweight losses; if the latter are large, however, CCOs are detrimental for welfare. We show that optimal CCOs can suffer from time inconsistency, and also how political opportunism may limit CCO policy. Hence government credibility and reputation building emerge as critical for the successful implementation of CCOs.

Can Mobile Technologies Enhance Productivity? A Structural Model and Evidence from Benin Food Suppliers
Description: This paper analyzes the drivers of digital technologies adoption and how it affects the productivity of small scale businesses in Africa. We use data collected from two semi-rural markets in Benin, where grains and legumes are key staple foods and one-third of the population has internet access. We develop a structural model to rationalize digital technologies adoption—defined as the use of mobile broadband internet connection through smartphones—as well as usage patterns and outcomes observed in the data. The model’s implications are empirically tested using both reduced-form and structural maximum likelihood estimations. We find that younger, wealthier, more educated grains and legumes suppliers and those closely surrounded by other users are more likely to adopt digital technologies. Adopters perform 4-5 more business transactions each month than non-adopters on average, suggesting that digital technologies adoption could raise the monthly frequency and amounts of trades by up to 50%. Most adopters are women, but their productivity gains are lower than their male counterparts. Counterfactual policy simulations with the estimated model suggest that upgrading the broadband internet quality yields the largest improvement in adoption rate and productivity gains, while reducing its cost for a given connection quality only has a moderate effect. Improving access to credit only increases the adoption rate of constrained suppliers.

Climate Policies and External Adjustment
Description: This paper assesses the economic effects of climate policies on different regions and countries with a focus on external adjustment. The paper finds that various climate policies could have substantially different impacts on external balances over the next decade. A credible and globally coordinated carbon tax would decrease current account balances in greener advanced economies and increase current accounts in more fossil-fuel-dependent regions, reflecting a disproportionate decline in investment for the latter group. Green supply-side policies—green subsidy and infrastructure investment—would increase investment and saving but would have a more muted external sector impact because of the constrained pace of expansion for renewables or the symmetry of the infrastructure boost. Country characteristics, such as initial carbon intensity and net fossil fuel exports, ultimately determine the current account responses. For the global economy, a coordinated climate change mitigation policy package would shift capital towards advanced economies. Following an initial rise, the global interest rates would fall over time with increases in the carbon tax. These external sector effects, however, depend crucially on the degree of international policy coordination and credibility.

The Mirage of Falling R-stars
Description: Was the recent decline in real interest rates driven by a diminishing natural real interest rate, or have we observed a long sequence of shocks that have pushed market rates below the equilibrium level? In this paper we show on a sample of 12 open economies that once we account for equilibrium real exchange rate appreciation/depreciation, the natural real interest rate in the 2000s and 2010s is no longer found to be declining to near or below zero. The explicit inclusion of equilibrium real exchange rate appreciation in the identification of the natural rate is the main deviation from the Laubach-Williams approach. On top of that, we use a full-blown semi-structural model with a monetary policy rule and expectations. Bayesian estimation is used to obtain parameter values for individual countries.

The Green Future: Labor Market Implications for Men and Women
Description: This study examines the green transition's effects on labor markets using a task-based framework to identify jobs with tasks that contribute, or with the potential to contribute, to the green transition. Analyzing data from Brazil, Colombia, South Africa, the United Kingdom, and the United States, we find that the proportion of workers in green jobs is similar across AEs and EMs, albeit with distinct occupational patterns: AE green job holders typically have higher education levels, whereas in EMs, they tend to have lower education levels. Despite these disparities, the distribution of green jobs across genders is similar across countries, with men occupying over two-thirds of these positions. Furthermore, green jobs are characterized by a wage premium and a narrower gender pay gap. Our research further studies the implications of AI for the expansion of green employment opportunities. This research advances our understanding of the interplay between green jobs, gender equity, and AI and provides valuable insights for promoting a more inclusive green transition.

Policy Options for Climate Mitigation: Emissions Trading Schemes in Asia-Pacific
Description: Large reductions in global emissions are needed for the world to be on track to meet global temperature goals. Asia-Pacific countries have a critical role in emissions reduction given their large and rising share in global emissions. This paper discusses the main opportunities and behavioral responses for reducing emissions, and commonly used mitigation instruments. It then considers key design issues for carbon pricing, with a focus on emissions trading schemes (ETS), describes measures to overcome the obstacles to carbon pricing, and discusses experiences with carbon pricing relevant for Asia-Pacific economies. Lastly, the paper covers complementary policy reforms, including reinforcing mitigation instruments, public investment, fuel tax reform, green industrial policies, and supporting reforms to the energy sector. Carbon pricing, including ETSs can be the centerpiece of climate mitigation strategies for most countries, particularly if ETSs are designed to mimic some of the administrative and economic attractions of carbon taxes and implemented appropriately.
