A National Wealth Approach to Banking Crises and Financial Stability
Description: The paper explores a different, supplementary way to assess and manage a particular type of banking crises, those arising from a rise of nonperforming loans to the corporate sector. It relies on a “national wealth approach,” focusing on the distribution of net wealth among economic sectors and its interaction with developments in the banking system. It identifies avenues for policy response optimization, based on an integrated macrofinancial analytical framework, both for the prevention and the resolution of these types of economic events.

Did the Global Financial Crisis Break the U.S. Phillips Curve?
Description: Inflation dynamics, as well as its interaction with unemployment, have been puzzling since the Global Financial Crisis (GFC). In this empirical paper, we use multivariate, possibly time-varying, time-series models and show that changes in shocks are a more salient feature of the data than changes in coefficients. Hence, the GFC did not break the Phillips curve. By estimating variations of a regime-switching model, we show that allowing for regime switching solely in coefficients of the policy rule would maximize the fit. Additionally, using a data-rich reduced-form model we compute conditional forecast scenarios. We show that financial and external variables have the highest forecasting power for inflation and unemployment, post-GFC.

What is Keeping U.S. Core Inflation Low: Insights from a Bottom-Up Approach
Description: Over the past two decades, U.S. core PCE goods and services inflation have evolved differently. Against the backdrop of global concerns of low inflation, we use this trend as motivation to develop a bottom-up model of U.S. inflation. We find that domestic forces play a larger role relative to foreign factors in influencing core services inflation, while foreign factors predominantly drive core goods price changes. When comparing forecasting performance, we find that both the aggregate Phillips curve and the bottom up approach give low root mean square errors. The latter, however, is more informative in tracing the effects of shocks and understanding the exact channels through which they affect aggregate inflation. Using scenario analysis—and given a relatively low sensitivity of core inflation to changes in slack, both at the aggregate Phillips curve and sub-components levels—we find that global pressures will likely keep core PCE inflation below 2 percent for the foreseeable future unless the dollar starts to depreciate markedly and the unemployment rate goes well below the natural rate. These results support the accommodative stance of monetary policy pursued thus far and, going forward, underscore the need for proceeding cautiously and very gradually in raising the federal funds rate.

Syria’s Conflict Economy
Description: Five years into the ongoing and tragic conflict, the paper analyzes how Syria’s economy and its people have been affected and outlines the challenges in rebuilding the economy. With extreme limitations on information, the findings of the paper are subject to an extraordinary degree of uncertainty. The key messages are: (1) that the devastating civil war has set the country back decades in terms of economic, social and human development. Syria’s GDP today is less than half of what it was before the war started and it could take two decades or more for Syria to return to its pre-conflict GDP levels; and that (2) while reconstructing damaged physical infrastructure will be a monumental task, rebuilding Syria’s human and social capital will be an even greater and lasting challenge.

What's Up with U.S. Wage Growth and Job Mobility?
Description: Since the global financial crisis, US wage growth has been sluggish. Drawing on individual earnings data from the 2000–15 Current Population Survey, I find that the drawn-out cyclical labor market repair—likely owing to low entry wages of new workers—slowed down real wage growth. There are, however, also signs of structural changes in the labor market affecting wages: for full-time, full-employed workers, the Wage-Phillips curve—the empirical relationship between wage growth and the unemployment rate—has become horizontal after 2008. Similarly, job-turnover rates have continued to decline. Job-to-job transitions—associated with higher wage growth—have slowed across all skill and age groups and beyond what local labor market conditions would imply. This raises concerns about the allocative ability of the labor market to adjust to changing economic conditions.

Income Polarization in the United States
Description: The paper uses a combination of micro-level datasets to document the rise of income polarization—what some have referred to as the “hollowing out” of the income distribution—in the United States, since the 1970s. While in the initial decades more middle-income households moved up, rather than down, the income ladder, since the turn of the current century, most of polarization has been towards lower incomes. This result is striking and in contrast with findings of other recent contributions. In addition, the paper finds evidence that, after conditioning on income and household characteristics, the marginal propensity to consume from permanent changes in income has somewhat fallen in recent years. We assess the potential impacts of these trends on private consumption. During 1998-2013, the rise in income polarization and lower marginal propensity to consume have suppressed the level of real consumption at the aggregate level, by about 3½ percent—equivalent to more than one year of consumption.

Monetary Policy Implementation and Volatility Transmission along the Yield Curve: The Case of Kenya
Description: This paper analyzes the degree to which volatility in interbank interest rates leads to volatility in financial instruments with longer maturities (e.g., T-bills) in Kenya since 2012, year in which the monetary policy framework switched to a forward-looking approach, relative to seven other inflation targeting (IT) countries (Ghana, Hungary, Poland, South Africa, Sweden, Thailand, and Uganda). Kenya shows strong volatility transmission and high persistence similar to other countries in transition to a more forward-looking monetary policy framework. These results emphasize the importance of a strong commitment to an interbank rate as an operational target and suggest that the central bank could reduce uncertainty in short-term yields significantly by smoothing out the overnight interest rates around the policy rate.

The Impact of Product Market Reforms on Firm Productivity in Italy
Description: This paper examines the role of removing obstacles to competition in product markets in raising growth and productivity. Using firm-level data from Italy during 2003–13 and OECD measures of product market regulation, we estimate the effect of deregulation in network sectors on value added and productivity of firms in these sectors, as well as firms using these intermediates in their production processes. We find evidence of a significant positive impact. These effects are more pronounced in Italian provinces with more efficient public administration, underscoring the complementarities of advancing public administration and product market reforms simultaneously.

Women’s Opportunities and Challenges in Sub-Saharan African Job Markets
Description: As labor market data is scarce in Sub-Saharan Africa (SSA), this paper uses household survey data to analyze the determinants of the gender gap in the labor market and its welfare implications for five SSA countries in multinomial logit models with propensity score matching method. The analysis confirms that education opens up opportunities for women to escape agricultural feminization and engage in formal wage employment, but these opportunities diminish when women marry—a disadvantage increasingly relevant when countries develop and urbanization progresses. Opening a household enterprise offers women an alternative avenue to escape low-paid jobs in agriculture, but the increase in per capita income is lower than male-owned household enterprises. These findings underline that improving women’s education needs to be supported by measures to allow married women to keep their jobs in the wage sector.

The Impact of Trade Agreements: New Approach, New Insights
Description: The Trans-Pacific Partnership (TPP) has reinvigorated research on the ex-ante impact of trade agreements. The results from these ex-ante models are subject to considerable uncertainties, and needs to be complimented by ex-post studies. The paper fills this gap in recent literature by employing synthetic control methods (SCM) – currently extremely popular in micro and macro studies – to understand the impact of trade agreements in the period 1983–1995 for 104 country pairs. The key advantage of using SCM to address selection bias – one of the persisting issues in trade literature – is that it allows the effect of unobserved confounder to vary with time, as opposed to traditional econometric methods that can deal with time-invariant unobserved country characteristics. Using SCM approach, the paper finds that trade agreements can generate substantial gains, on average an increase of exports by 80 percentage points over ten years. The export gains are higher when emerging markets have trade agreements with advanced markets. The paper shows that all the countries in NAFTA have substantially gained due to NAFTA. Finally, there is some evidence that trade agreements can potentially lead to slight import diversion, but not export diversion.
