Macro-Financial Linkages and Heterogeneous Non-Performing Loans Projections: An Application to Ecuador
Description: We propose a stress testing framework of credit risk, which analyzes macro-financial linkages, generates consistent forecasts of macro-financial variables, and projects non-performing loans (NPL) on the basis of such forecasts. Economic contractions are generally associated with increases in NPL. However, despite the common assumption used in the empirical literature of homogeneous impact across banks, the strength of this relationship is often bank-specific, and imposing homogeneity may lead to over or underestimating the resilience of the financial system to macroeconomic woes. Our approach accounts for banks’ heterogeneous reaction to macro-financial shocks in a dynamic context and potential cross-sectional dependence across banks caused by common shocks. An application to Ecuador suggests that substantial heterogeneity is present and that this should be taken into account when trying to anticipate inflections in the quality of portfolio.

Real Effects of Capital Inflows in Emerging Markets
Description: We examine the association between capital inflows and industry growth in a sample of 22 emerging market economies from 1998 to 2010. We expect more external finance dependent industries in countries that host more capital inflows to grow disproportionately faster. This is indeed the case in the pre-crisis period of 1998–2007, and is driven by debt, rather than equity, inflows. We also observe a reduction in output volatility but this association is more pronounced for equity, rather than debt, inflows. These relationships, however, break down during the crisis, hinting at the importance of an undisrupted global financial system for emerging markets to harness the growth benefits of capital inflows. In line with this observation, we also document that the inflows-growth nexus is stronger in countries with well-functioning banks.

Tax Capacity and Growth: Is there a Tipping Point?
Description: Is there a minimum tax to GDP ratio associated with a significant acceleration in the process of growth and development? We give an empirical answer to this question by investigating the existence of a tipping point in tax-to-GDP levels. We use two separate databases: a novel contemporary database covering 139 countries from 1965 to 2011 and a historical database for 30 advanced economies from 1800 to 1980. We find that the answer to the question is yes. Estimated tipping points are similar at about 12¾ percent of GDP. For the contemporary dataset we find that a country just above the threshold will have GDP per capita 7.5 percent larger, after 10 years. The effect is tightly estimated and economically large.

Political Institutions, State Building, and Tax Capacity: Crossing the Tipping Point
Description: An empirical finding by Gaspar, Jaramillo and Wingender (2016) shows that once countries cross a tax-to-GDP threshold of around 12¾ percent, real GDP per capita increases sharply and in a sustained manner over the following decade. In this paper, we attempt via four case studies—Spain, China, Colombia, and Nigeria—to illustrate that the improvements in tax capacity have been part of a deeper process of state capacity building. We discuss the political conditions that supported tax capacity building, highlighting three important political ingredients: constitutive institutions, inclusive politics and credible leadership.

Minimum Wage as a Wage Policy Tool in Japan
Description: Using prefectural data, we study the potential impact on wage dynamics of the planned minimum wage increase policy in Japan. Our main result is that stepping up minimum wage growth from 2 to the planned 3 percent per year could raise wage growth by 0.5 percent annually. Given Japan’s need for income policies to generate vigorous wage-price dynanics, reflecting the 2 percent inflation target, one policy implication of this finding is that, while the minimum wage plan will help boost wages, it should be accompanied by other, more “unorthodox” income policies, such as a “soft target” for private sector wage growth through a “comply -or-explain mechanism” for wage growth and increases in public wages in line with the inflation target.

System Priors for Econometric Time Series
Description: The paper introduces “system priors”, their use in Bayesian analysis of econometric time series, and provides a simple and illustrative application. System priors were devised by Andrle and Benes (2013) as a tool to incorporate prior knowledge into an economic model. Unlike priors about individual parameters, system priors offer a simple and efficient way of formulating well-defined and economically-meaningful priors about high-level model properties. The generality of system priors are illustrated using an AR(2) process with a prior that most of its dynamics comes from business-cycle frequencies.

Fiscal Discipline and Exchange Rates: Does Politics Matter?
Description: We look at the effect of exchange rate regimes on fiscal discipline, taking into account the effect of underlying political conditions. We present a model where strong politics (defined as policymakers facing longer political horizon and higher cohesion) are associated with better fiscal performance, but fixed exchange rates may revert this result and lead to less fiscal discipline. We confirm these hypotheses through regression analysis performed on a panel sample covering 79 countries from 1975 to 2012. Our empirical results also show that the positive effect of strong politics on fiscal discipline is not enough to counter the negative impact of being at/moving to fixed exchange rates. Finally, we use the synthetic control method to illustrate how the transition from flexible to fully fixed exchange rate under the Euro impacted negatively fiscal discipline in European countries. Our results are robust to a number of important sensitivity checks, including different estimators, alternative proxies for fiscal discipline, and sub-sample analysis.

Non-Performing Loans in the ECCU: Determinants and Macroeconomic Impact
Description: This paper assesses the determinants of NPLs in the Eastern Caribbean Currency Union (ECCU) and whether a deterioration in asset quality may result in negative feedback effects from the banking system to economic activity. The results suggest that the deterioration in asset quality can be attributed to both macroeconomic and bank-specific factors. Banks with stronger profitability and lower exposure to the construction sector and household loans tend to have lower NPLs. Further, some evidence indicates that foreign owned banks systematically have lower NPLs than domestic banks, pointing to the presence of important differences across bank practices with an impact on asset quality. Finally, the results emphasize the strength of macrofinancial feedback loops in the ECCU.

Forecast Errors and Uncertainty Shocks
Description: Macroeconomic forecasts are persistently too optimistic. This paper finds that common factors related to general uncertainty about U.S. macrofinancial prospects and global demand drive this overoptimism. These common factors matter most for advanced economies and G- 20 countries. The results suggest that an increase in uncertainty-driven overoptimism has dampening effects on next-year real GDP growth rates. This implies that incorporating the common structure governing forecast errors across countries can help improve subsequent forecasts.

Whose Credit Line is it Anyway: An Update on Banks' Implicit Subsidies
Description: The post-crisis financial sector framework reform remains incomplete. While capital and liquidity requirements have been strengthened, doubts remain over other aspects, including the fact that expectations of government support for systemically-important banks (SIBs) remain intact. In this paper, we use a jump diffusion option-pricing approach to provide estimates of implicit subsidies gained by these banks due to the expectation of protection to creditors provided by governments. While these subsidies have declined in the post-crisis era as volatility has declined and capital levels have increased, they remain non-trivial. Even conservative parameterizations of default and loss probabilities lead to macroeconomically significant figures.
