Breaking the Bank? A Probabilistic Assessment of Euro Area Bank Profitability
Description: This paper explores the determinants of profitability across large euro area banks using a novel approach based on conditional profitability distributions. Real GDP growth and the NPL ratio are shown to be the most reliable determinants of bank profitability. However, the estimated conditional distributions reveal that, while higher growth would raise profits on average, a large swath of banks would most likely continue to struggle even amid a strong economic recovery. Therefore, for some banks, a determined reduction in NPLs combined with cost efficiency improvements and customized changes to their business models appears to be the most promising strategy for durably raising profitability.

Governance and State-Owned Enterprises: How Costly is Corruption?
Description: State-owned enterprises (SOEs) are present in key sectors of the economies around the world. While they can provide an important public service, there is widespread concern that their activities are negatively affected by corruption. However, there is limited cross-country analysis on the costs of corruption for SOEs. We present new evidence on how corruption affects the performance of SOEs using firm level data across a large number of countries. One striking result is that SOEs perform as well as private firms in core sectors when corruption is low. Taking advantage of a novel database reforms, we also show that SOE governance reforms can generate significant performance gains.

Designing Central Bank Digital Currencies
Description: We study the optimal design of a central bank digital currency (CBDC) in an environment where agents sort into cash, CBDC and bank deposits according to their preferences over anonymity and security; and where network effects make the convenience of payment instruments dependent on the number of their users. CBDC can be designed with attributes similar to cash or deposits, and can be interest-bearing: a CBDC that closely competes with deposits depresses bank credit and output, while a cash-like CBDC may lead to the disappearance of cash. Then, the optimal CBDC design trades off bank intermediation against the social value of maintaining diverse payment instruments. When network effects matter, an interest-bearing CBDC alleviates the central bank's tradeoff.

Managed Trade: What Could be Possible Spillover Effects of a Potential Trade Agreement Between the U.S. and China?
Description: The trade discussions between the U.S. and China are on-going. Not much is known about the shape and nature of a potential agreement, but it seems possible that it would include elements of managed trade. This paper attempts to examine the direct, first-round spillover effects for the rest of the world from managed trade using three approaches. The results suggest that, in the absence of a meaningful boost in China’s domestic demand and imports, bilateral purchase commitments are likely to generate substantial trade diversion effects for other countries. For example, the European Union, Japan, and Korea are likely to have significant export diversion in a potential deal that includes substantial purchases of U.S. vehicles, machinery, and electronics by China. At the same time, a deal that puts greater emphasis on commodities would put small commodity exporters at a risk. This points to the advantages of a comprehensive agreement that supports the international system and avoids managed bilateral trade arrangements.

Integrating Solvency and Liquidity Stress Tests: The Use of Markov Regime-Switching Models
Description: The paper presents a framework to integrate liquidity and solvency stress tests. An empirical study based on European bond trading data finds that asset sales haircuts depend on the total amount of assets sold and general liquidity conditions in the market. To account for variations in market liquidity, the study uses Markov regime-switching models and links haircuts with market volatility and the amount of securities sold by banks. The framework is accompanied by a Matlab program and an Excel-based tool, which allow the calculations to be replicated for any type of traded security and to be used for liquidity and solvency stress testing.

Bridging the Mobile Digital Divide in Sub-Saharan Africa: Costing under Demographic Change and Urbanization
Description: Digital connectivity, including through the modern cellular network technologies, is expected to play a key role for the Future of Work in sub-Saharan Africa (SSA). We estimate the cost of introducing a full-scale 4G network by 2025 in SSA and an operable 5G network by 2040. We adapt the costing model of Lombardo (2019) by accounting for the significant demographic transformation and rapid urbanization in SSA. We use the WorldPop and GADM databases and the UN’s medium-variant population projections to project the population densities at the highest level of administrative division for each SSA country in 2025 and 2040. For full 4G connectivity, the required capital and operational costs stands approximately at US$14 billion by 2025 and for 5G connectivity, costs amount to US$57 billion in 2040, conditional on having the 4G in place by 2025. These costs roughly translate to 8.4 percent of annual subscriber income, on a median basis, by 2025 for 4G and 4.9 percent of subscriber income by 2040 for 5G. Having the infrastructure in place is not sufficient to bridge the mobile Digital Divide. In addition, policies are needed to address affordability and knowledge gaps.

Assessing House Prices in Canada
Description: This paper assesses house prices in 11 Canadian Census Metropolitan Areas (CMA) using the borrowing-capacity and the net-present-value approaches. The results indicate that by the end of 2018, house prices in most metropolitan areas are aligned with macroeconomic fundamentals. However, in Hamilton, Toronto, and Vancouver house prices have increased beyond the values implied by the fundamentals.

Financial Conditions and Growth at Risk in the ECCU
Description: We study the growth determinants in the Eastern Caribbean Currency Union (ECCU), using the Growth at Risk (GaR) framework with a focus on financial variables. We find that excessive bank credit growth is associated with lower future real GDP growth in the medium term especially on the low quantiles of growth distribution. Moreover, worsening of both global financial conditions and external conditions are associated with lower future growth in the short term, especially at the high quantiles of growth distribution. Country-specific results are broadly in line with ECCU-wide results, with some variation potentially due to the strong Citizenship-By-Investment program inflows and lack of credit union data. The establishment of a macroprudential framework in the ECCU would need to pay close attention to credit growth not only of banks but also credit unions and continue to monitor global and external conditions.

Macrofinancial Linkages and Growth at Risk in the Dominican Republic
Description: This paper uses the Growth-at-Risk (GaR) methodology to examine how macrofinancial conditions affect the growth outlook and its probability distribution. Using this approach, we evaluate risks to GDP growth in the Dominican Republic using quarterly data for 1996-2018. We group macrofinancial conditions in five principal determinants, based on 32 indicators. The Dominican Republic’s growth distribution appears most vulnerable to negative shocks to domestic financial conditions, domestic leverage, domestic demand, and external demand, with additional repercussions from the external cost of borrowing in the longer run. Our findings show that domestic monetary policy plays a particularly important role in reducing growth vulnerabilities when the economy is weak.

Pricing Sovereign Debt in Resource-Rich Economies
Description: How do oil price movements affect sovereign spreads in an oil-dependent economy? I develop a stochastic general equilibrium model of an economy exposed to co-moving oil price and output processes, with endogenous sovereign default risk. The model explains a large proportion of business cycle fluctuations in interest-rate spreads in oil-exporting emerging market economies, particularly the countercyclicallity of interest rate spreads and oil prices. Higher risk-aversion, more impatient governments, larger oil shares and a stronger correlation between domestic output and oil price shocks all lead to stronger co-movements between risk premiums and the oil price.
