A Model to Assess the Probabilities of Growth, Fiscal, and Financial Crises
Description: This paper summarizes a suite of early warning models to assess the probabilities of growth, fiscal, and financial crises in advanced economies and emerging markets. We estimate separate signal-extraction models for each type of crisis and sample of countries, and we use our results to generate “histories of vulnerabilities” for countries, regions, and the world. For the global financial crisis, our models report that vulnerabilities in advanced economies were rooted in the bursting of leveraged bubbles, while vulnerabilities in emerging markets stemmed from lengthy booms in credit and asset prices combined with growing weaknesses in the corporate and external sectors.

The Impact of Fiscal Consolidations on Growth in Sub-Saharan Africa
Description: This paper examines the output effects of changes in public expenditure and revenue in sub-Saharan African countries during 1990–2016. Fiscal multipliers in sub-Saharan Africa are somewhat smaller than those in advanced and emerging economies. The effect of changes in fiscal policy on output depends on the composition: cutting public investment has a larger effect on output than cutting public consumption or raising revenue. Episodes of fiscal consolidation have short- and medium-term output effects, but here, too, composition matters: fiscal consolidations based on reducing public investment have the largest effect on output, while fiscal consolidations based on revenue mobilization are less harmful than those based on public investment cuts. These findings suggest that the negative impact on growth can be mitigated through the design of fiscal adjustment and the accompanying policy environment.

Sovereign Risk and Bank Risk-Taking
Description: I propose a dynamic general equilibrium model in which strategic interactions between banks and depositors may lead to endogenous bank fragility and slow recovery from crises. When banks' investment decisions are not contractible, depositors form expectations about bank risk-taking and demand a return on deposits according to their risk. This creates strategic complementarities and possibly multiple equilibria: in response to an increase in funding costs, banks may optimally choose to pursue risky portfolios that undermine their solvency prospects. In a bad equilibrium, high funding costs hinder the accumulation of bank net worth, leading to a persistent drop in investment and output. I bring the model to bear on the European sovereign debt crisis, in the course of which under-capitalized banks in defaultrisky countries experienced an increase in funding costs and raised their holdings of domestic government debt. The model is quantified using Portuguese data and accounts for macroeconomic dynamics in Portugal in 2010-2016. Policy interventions face a trade-off between alleviating banks' funding conditions and strengthening risk-taking incentives. Liquidity provision to banks may eliminate the good equilibrium when not targeted. Targeted interventions have the capacity to eliminate adverse equilibria.

International Commodity Prices and Domestic Bank Lending in Developing Countries
Description: We study the role of the bank-lending channel in propagating fluctuations in commodity prices to credit aggregates and economic activity in developing countries. We use data on more than 1,600 banks from 78 developing countries to analyze the transmission of changes in international commodity prices to domestic bank lending. Identification relies on a bankspecific time-varying measure of bank sensitivity to changes in commodity prices, based on daily data on bank stock prices. We find that a fall in commodity prices reduces bank lending, although this effect is confined to low-income countries and driven by commodity price busts. Banks with relatively lower deposits and poor asset quality transmit commodity price changes to lending more aggressively, supporting the hypothesis that the overall credit response to commodity prices works also through the credit supply channel. Our results also show that there is no significant difference in the behavior of foreign and domestic banks in the transmission process, reflecting the regional footprint of foreign banks in developing countries.

Firms and the Decline in Earnings Inequality in Brazil
Description: We document a large decrease in earnings inequality in Brazil between 1996 and 2012. Using administrative linked employer-employee data, we fit high-dimensional worker and firm fixed effects models to understand the sources of this decrease. Firm effects account for 40 percent of the total decrease and worker effects for 29 percent. Changes in observable worker and firm characteristics contributed little to these trends. Instead, the decrease is primarily due to a compression of returns to these characteristics, particularly a declining firm productivity pay premium. Our results shed light on potential drivers of earnings inequality dynamics.

Job Protection Deregulation in Good and Bad Times
Description: This paper explores the short-term employment effect of deregulating job protection for regular workers and how it varies with prevailing business cycle conditions. We apply a local projection method to a newly constructed “narrative” dataset of major regular job protection reforms covering 26 advanced economies over the past four decades. The analysis relies on country-sector-level data, using as an identifying assumption the fact that stringent dismissal regulations are more binding in sectors that are characterized by a higher “natural” propensity to regularly adjust their workforce. We find that the responses of sectoral employment to large job protection deregulation shocks depend crucially on the state of the economy at the time of reform——they are positive in an expansion, but become negative in a recession. These findings are consistent with theory, and are robust to a broad range of robustness checks including an Instrumental Variable approach using political economy drivers of reforms as instruments. Our results provide a case for undertaking job protection reform in good times, or for designing it in ways that enhance its short-term impact.

Collective Bargaining Through the Magnifying Glass: A Comparison Between the Netherlands and Portugal
Description: Since the global financial crisis, sector-level bargaining has come under renewed scrutiny. While in Southern Europe, the crisis raised concerns about the role of collective bargaining as an obstacle to labor market adjustment, in Northern Europe it was perceived more favourably and, according to some, may even have helped to weather the fallout of the crisis more easily. This paper seeks to contribute to a deeper understanding of sector-level bargaining systems and their role for labor market performance. We compare two countries with seemingly similar collective bargaining systems, the Netherlands and Portugal, and document a number of features that may affect labor market outcomes, including: i) the scope for flexibility at the firm or worker level within sector-level agreements; ii) the emphasis on representativeness as a criterion for extensions; iii) the effectiveness of coordination across bargaining units; and iv) pro-active government policies to enhance trust and cooperation between the social partners.

Credit and Fiscal Multipliers in China
Description: We jointly estimate credit and fiscal multipliers in China. We use the tenure of the provincial party secretary, interacted with the type of stimulus used in other provinces, to obtain separate instruments for provincial credit and government expenditure. We estimate a fiscal multiplier of 0.8 and a credit multiplier of 0.2 in 2001-2015. The multipliers have changed over time. The fiscal multiplier has increased from 0.75 in 2001-2008 to 1.4 in 2010-2015. The credit multiplier has declined from 0.17 to zero over the same periods. Our results suggest that reducing credit growth in China is unlikely to disrupt output growth, whereas fiscal policy may be effective in supporting macroeconomic adjustment.

Reassessing the Perimeter of Government Accounts in China
Description: China’s official general government accounts do not include off-budget quasi-fiscal spending unlike the IMF’s augmented government accounts. This paper argues that the broader concept of augmented government remains relevant despite recent positive measures to separate off-budget units from the government. In fact, new avenues to finance public infrastructure, such as Special Construction Funds and Government Guided Funds, have emerged and this paper re-defines the perimeter of augmented government to include them. Finally, concrete steps for improving China’s fiscal accounts are put forward. If these steps are taken, the perimeter of general government would expand relative to official statistics but would likely be narrower than where augmented aggregates place it.

Welfare vs. Income Convergence and Environmental Externalities
Description: We present estimates of welfare by country for 2007 and 2014 using the methodology of Jones and Klenow (2016) which incorporates consumption, leisure, mortality and inequality, and we extend the methodology to include environmental externalities. During the period of the global financial crisis welfare grew slightly more rapidly than income per capita, mainly due to improvements in life expectancy. This led to welfare convergence in most regions towards advanced country levels. Introducing environmental effects changes the welfare ranking for countries that rely heavily on natural resources, highlighting the importance of the natural resource base in welfare. This methodology could provide a theoretically consistent and tractable way of monitoring progress in several Sustainable Development Goal (SDG) indicators.
