Public Investment Scaling-up and Debt Sustainability: The Case of Energy Sector Investments in the Caribbean
Description: The question of how scaling up public investment could affect fiscal and debt sustainability is key for countries needing to fill infrastructure gaps and build resilience. This paper proposes a bottom-up approach to assess large public investments that are potentially self-financing and reflect their impact in macro-fiscal projections that underpin the IMF’s Debt Sustainability Analysis Framework. Using the case of energy sector investments in Caribbean countries, the paper shows how to avoid biases against good projects that pay off over long horizons and ensure that transformative investments are not sacrificed to myopic assessments of debt sustainability risks. The approach is applicable to any macro-critical investment for which user fees can cover financing costs and which has the potential to raise growth without crowding-out.

Heterogeneity of Bank Risk Weights in the EU: Evidence by Asset Class and Country of Counterparty Exposure
Description: Concerns about excessive variability in bank risk weights have prompted their review by regulators. This paper provides prima facie evidence on the extent of risk weight heterogeneity across broad asset classes and by country of counterparty for major banks in the European Union using internal models. It also finds that corporate risk weights are sensitive to the riskiness of an average representative firm, but not to a market indicator of a firm’s probablity of default. Under plausible yet severe hypothetical scenarios for harmonized risk weights, counterfactual capital ratios would decline significantly for some banks, but they would not experience a shortfall relative to Basel III’s minimum requirements. This, however, does not preclude falling short of meeting additional national supervisory capital requirements.

ABBA: An Agent-Based Model of the Banking System
Description: A thorough analysis of risks in the banking system requires incorporating banks’ inherent heterogeneity and adaptive behavior in response to shocks and changes in business conditions and the regulatory environment. ABBA is an agent-based model for analyzing risks in the banking system in which banks’ business decisions drive the endogenous formation of interbank networks. ABBA allows for a rich menu of banks’ decisions, contingent on banks’ balance sheet and capital position, including dividend payment rules, credit expansion, and dynamic balance sheet adjustment via risk-weight optimization. The platform serves to illustrate the effect of changes on regulatory requirements on solvency, liquidity, and interconnectedness risk. It could also constitute a basic building block for further development of large, bottom-up agent-based macro-financial models.

Capital Controls and the Cost of Debt
Description: Using a panel data set for international corporate bonds and capital account restrictions in advanced and emerging economies, we show that restrictions on capital inflows produce a substantial and economically meaningful increase in corporate bond spreads. A number of heterogeneities suggest that the effect of capital controls on inflows is particularly strong for more financially constrained firms, establishing a novel channel through which capital controls affect economic outcomes. By contrast, we do not find a robust significant effect of restrictions on outflows.

Financial Frictions, Underinvestment, and Investment Composition: Evidence from Indian Corporates
Description: This paper studies private investment in India against the backdrop of a significant investment decline over the past decade. We analyze the potential causes of weaker investment at the firm level, using both firm-level financial statements and a novel dataset on firms’ investment project decisions, and find that financial frictions have played a role in the slowdown. Firms with higher financial leverage invest less, as do firms with lower earnings relative to their interest expenses. Consistent with the notion of credit constraints leading to pro-cyclical investment, we also find that firms with higher leverage are (i) less likely to undertake new investment projects, (ii) less likely to complete investment projects once begun, and (iii) undertake shorter-term investment projects.

Bottom-Up Default Analysis of Corporate Solvency Risk: An Application to Latin America
Description: This paper suggests a novel approach to assess corporate sector solvency risk. The approach uses a Bottom-Up Default Analysis that projects probabilities of default of individual firms conditional on macroeconomic conditions and financial risk factors. This allows a direct macro-financial link to assessing corporate performance and facilitates what-if scenarios. When extended with credit portfolio techniques, the approach can also assess the aggregate impact of changes in firm solvency risk on creditor banks’ capital buffers under different macroeconomic scenarios. As an illustration, we apply this approach to the corporate sector of the five largest economies in Latin America.

Deposit Insurance, Remittances, and Dollarization: Survey-Based Evidence from a Top Remittance-Receiving Country
Description: The paper uses a unique survey of remittance-receiving individuals from Tajikistan to study the impact of policy awareness on consumer behavior. The results show that knowledge of deposit insurance encourages the use of formal channels for transmitting remittances and reduces dollarization. Given the size and importance of remittances in Tajikistan, improving financial literacy and better publicizing details of the social safety net may encourage a more frequent use of formal channels for transferring remittances and reduce reliance on foreign exchange for transaction purposes. This is likely to improve bank profitability, enhance financial stability, and improve access to finance.

Financial Disruptions and the Cyclical Upgrading of Labor
Description: Amid total factor productivity (TFP) shocks job-to-job flows amplify the volatility of unemployment, but the aggregate implications of job-to-job flows amid financial shocks are less understood. To develop such understanding we model a general equilibrium labor-search framework that incorporates on-the-job (OTJ) search and distinctly accounts for the differential impact of TFP and financial shocks. Surprisingly, we find that the interaction of OTJ search with financial shocks is sufficiently different from its interaction with TFP shocks so that, under standard calibrations, our model generates aggregate dynamics exceedingly in line with the behavior of key U.S. macro data across several decades and in the wake of the Global Financial Crisis as well. Importantly, as in the data, the model yields relatively high volatilities of consumption, labor income, and unemployment. As such, our work contributes to resolving two limitations of current general equilibrium labor-search theory: under standard calibrations models without OTJ search generate implausibly low unemployment volatility, while models with OTJ search generate unemployment volatility closer to the data but at the expense of implausibly low consumption and labor-income volatility.

A Tie That Binds: Revisiting the Trilemma in Emerging Market Economies
Description: This paper examines the claim that exchange rate regimes are of little salience in the transmission of global financial conditions to domestic financial and macroeconomic conditions by focusing on a sample of about 40 emerging market countries over 1986–2013. Our findings show that exchange rate regimes do matter. Countries with fixed exchange rate regimes are more likely to experience financial vulnerabilities—faster domestic credit and house price growth, and increases in bank leverage—than those with relatively flexible regimes. The transmission of global financial shocks is likewise magnified under fixed exchange rate regimes relative to more flexible (though not necessarily fully flexible) regimes. We attribute this to both reduced monetary policy autonomy and a greater sensitivity of capital flows to changes in global conditions under fixed rate regimes.

Financial Frictions and the Great Productivity Slowdown
Description: We study the role of financial frictions in explaining the sharp and persistent productivity growth slowdown in advanced economies after the 2008 global financial crisis. Using a rich cross-country, firm-level data set and exploiting quasi-experimental variation in firm-level exposure to the crisis, we find that the combination of pre-existing firm-level financial fragilities and tightening credit conditions made an important contribution to the post-crisis productivity slowdown. Specifically: (i) firms that entered the crisis with weaker balance sheets experienced decline in total factor productivity growth relative to their less vulnerable counterparts after the crisis; (ii) this decline was larger for firms located in countries where credit conditions tightened more; (iii) financially fragile firms cut back on intangible capital investment compared to more resilient firms, which is one plausible way through which financial frictions undermined productivity. All of these effects are highly persistent and quantitatively large—possibly accounting on average for about a third of the post-crisis slowdown in within-firm total factor productivity growth. Furthermore, our results are not driven by more vulnerable firms being less productive or having experienced slower productivity growth before the crisis, or differing from less vulnerable firms along other dimensions.
