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.

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.

Policy Uncertainty in Japan
Description: We develop new economic policy uncertainty (EPU) indices for Japan from January 1987 onwards building on the approach of Baker, Bloom and Davis (2016). Each index reflects the frequency of newspaper articles that contain certain terms pertaining to the economy, policy matters and uncertainty. Our overall EPU index co-varies positively with implied volatilities for Japanese equities, exchange rates and interest rates and with a survey-based measure of political uncertainty. The EPU index rises around contested national elections and major leadership transitions in Japan, during the Asian Financial Crisis and in reaction to the Lehman Brothers failure, U.S. debt downgrade in 2011, Brexit referendum, and Japan’s recent decision to defer a consumption tax hike. Our uncertainty indices for fiscal, monetary, trade and exchange rate policy co-vary positively but also display distinct dynamics. VAR models imply that upward EPU innovations foreshadow deteriorations in Japan’s macroeconomic performance, as reflected by impulse response functions for investment, employment and output. Our study adds to evidence that credible policy plans and strong policy frameworks can favorably influence macroeconomic performance by, in part, reducing policy uncertainty.

Inclusive Growth Framework
Description: The paper suggests an operationally usable framework for the evaluation of growth inclusiveness—the inclusive growth framework (IGF). Based on the data on growth, poverty, and inequality, the framework allows for the quantitative assessment of growth inclusiveness. The assessment relies on the decomposition of the change in poverty into growth, distribution, and decile effects, which can be calculated using the Distributive Analysis Stata Package (DASP). Availability of at least two household surveys is the main precondition for the use of the IGF. The application of the IGF is illustrated with two country cases of Senegal and Djibouti.

Income Inequality and Education Revisited: Persistence, Endogeneity, and Heterogeneity
Description: This paper presents new results on the relationship between income inequality and education expansion—that is, increasing average years of schooling and reducing inequality of schooling. When dynamic panel estimation techniques are used to address issues of persistence and endogeneity, we find a large, positive, statistically significant and stable relationship between inequality of schooling and income inequality, especially in emerging and developing economies and among older age cohorts. The relationship between income inequality and average years of schooling is positive, consistent with constant or increasing returns to additional years of schooling. While this positive relationship is small and not always statistically significant, we find a statistically significant negative relationship with years of schooling of younger cohorts. Statistical tests indicate that our dynamic estimators are consistent and that our identifying instruments are valid. Policy simulations suggest that education expansion will continue to be inequality reducing. This role will diminish as countries develop, but it could be enhanced through a stronger focus on reducing inequality in the quality of education.

Structural Reform Packages, Sequencing, and the Informal Economy
Description: This paper explores the macroeconomic impacts of labor and product market deregulation using a small open-economy model with formal and informal markets. We examine both the long-run effects and the transition towards the post-reform equilibrium, while our main focus are reform packages and sequencing. The unofficial sector is a major determinant of the sign, and, in particular, the magnitude of responses. South Africa, an emerging country, is considered when Bayesian estimating the model. Regarding the long run, both labor and product market reforms considerably increase output, although labor market reforms are more successful in decreasing unemployment. Nevertheless, there are short-term costs, for example, a decrease in household consumption, net exports or output, or a decrease in competition. Combining reforms, especially with product market deregulation, are good at reducing short-term costs. Finally, concerning the speed of adjustment, it is usually better to start with a labor market reform.

Labor Market Adjustments to Shocks in Australia
Description: Labor markets in Australia have adjusted smoothly to significant declines in commodity prices with little increase in unemployment. This paper examines several aspects of the adjustment, focusing on (i) evidence of increased labor market frictions following the commodity price decline; (ii) flexibility in labor input adjustment in response to demand shocks; (iii) changes in labor productivity in the wake of resource reallocation with the decline in mining investment, (iv) and the role of migration in adjusting to the commodity price and mining investment cycle. We find little evidence of increased labor market frictions with the decline in commodity prices. The relatively smooth transition has been assisted by increased flexibility in adjustment of worker hours over time. Labor productivity growth has sustained its historical average through the transition, despite some temporary drag as the economy rebalances. Finally, migration has played a key role in labor market adjustment through the commodity cycle.

The Algebraic Galaxy of Simple Macroeconomic Models: A Hitchhiker’s Guide
Description: Simple macroeconomic frameworks like the IS/LM have survived because they help us conceptualize complex problems while also providing ‘back of the envelope’ estimates of macroeconomic outcomes. Herein, a bare-bones New Keynesian extension of the IS/LM model yields solutions for core macro variables (output gap, inflation, interest rate, real exchange rate misvaluation)—expressed in percent. We then extend that standard model to also generate a corresponding set of demand-side elements—expressed in currency units. A key aim of the paper is to reconcile these two metrics in ways that also aid communication and intuition—including through IS/LM-style graphs.

Trading with China: Productivity Gains, Job Losses
Description: We analyze the impact on productivity in advanced economies of fast-growing trade with China between the mid-1990s and late-2000s, separately identifying the export and import channels. We use country-sector-level data for 18 advanced economies and, similar to Autor, Dorn, and Hanson (2013), exploit exogenous variation in trade with China in a given country-sector by instrumenting imports from (exports to) China in a given country-sector with the average imports from (exports to) China in the same sector in other advanced economies. Our estimates point to large productivity gains from trading with China—the (exogenous) rise of China in global trade may have increased the level of total factor productivity by about 1.9 percent, or 12.3 percent of the overall increase over the sample period, in the median country-sector. By contrast, using a similar empirical strategy, we find adverse employment effects of Chinese imports in exposed country-industries, consistent with previous studies. Taken together, these findings point to large gains from free trade, while underscoring the scope for a more active policy role in redistributing them, particularly by easing workers’ transition between jobs and industries.

Disinflation, External Vulnerability, and Fiscal Intransigence: Some Unpleasant Mundellian Arithmetic
Description: This paper examines the policy challenges a country faces when it wants to both reduce inflation and maintain a sustainable external position. Mundell’s (1962) policy assignment framework suggests that these two goals may be mutually incompatible unless monetary and fiscal policies are properly coordinated. Unfortunately, if the fiscal authority is unwilling to cooperate—a case of fiscal intransigence—central banks that pursue a disinflation on a ‘go it alone’ basis will cause the country’s external position to further deteriorate. A dynamic analysis shows that if the central bank itself lacks credibility in its inflation goal, it must rely even more on cooperation from the fiscal authority than otherwise. Echoing Sargent and Wallace’s (1981) ‘unpleasant monetarist arithmetic,’ in these circumstances, a ‘go it alone’ policy may successfully stabilize prices and output, but only on a short-term basis.
