The Fiscal Cost of Conflict: Evidence from Afghanistan 2005-2016
Description: I use a monthly panel of provincially-collected central government revenues and conflict fatalities to estimate government revenues lost due to conflict in Afghanistan since 2005. I identify causal effects by instrumenting for conflict using pre-sample ethno-linguistic share. Headline estimates are very large, implying total revenue losses since 2005 of $3bn, and future revenue gains from peace of about 6 percent of GDP per year. Reduced collection efficiency, rather than lower economic activity, appears to be the key channel. OLS estimates understate the causal effect by a factor of four. Comparing to estimates from Powell’s (2017) generalized synthetic control method suggests that this bias results from omitted variables and measurement error in equal share. The findings underscore the considerable economic loss due to conflict, and the importance of careful identification in measuring this loss.

Cross-Border Credit Intermediation and Domestic Liquidity Provision in a Small Open Economy
Description: This paper develops a small open economy model where global and domestic liquidity is intermediated to the corporate sector through two financial processes. Investment banks intermediate cross-border credit through interlinked debt contracts to entrepreneurs and commercial banks intermediate domestic savings to liquidity constrained final good producers. Both processes are needed to facilitate development of key production inputs. The model captures procyclical investment bank leverage dynamics, global liquidity spillovers, domestic money market pressures, and macrofinancial linkages through which shocks propagate across the two processes, affecting spreads and balance sheets, as well as the real economy through investment and working capital channels.

Fintech, Inclusive Growth and Cyber Risks: Focus on the MENAP and CCA Regions
Description: Financial technology (fintech) is emerging as an innovative way to achieve financial inclusion and the broader objective of inclusive growth. Thus far, fintech in the MENAP and CCA remains below potential with limited impact on financial inclusion. This paper reviews the fintech landscape in the MENAP and CCA regions, identifies the constraints to the growth of fintech and its contribution to inclusive growth and considers policy options to unlock the potential.

Dollarization and Financial Development
Description: Despite significant strides in financial development over the past decades, financial dollarization, as reflected in elevated shares of foreign currency deposits and credit in the banking system, remains common in developing economies. We study the impact of financial dollarization, differentiating across foreign currency deposits and credit on financial depth, access and efficiency for a large sample of emerging market and developing countries over the past two decades. Panel regressions estimated using system GMM show that deposit dollarization has a negative impact on financial deepening on average. This negative impact is dampened in cases with past periods of high inflation. There is also some evidence that dollarization hampers financial efficiency. The results suggest that policy efforts to reduce dollarization can spur faster and safer financial development.

Household Wealth and Resilience to Financial Shocks in Italy
Description: High household wealth is often cited as a key strength of the Italian economy. Both in absolute terms and relative to income, the Italian household sector is wealthier than most euro area peers. A sizable fraction of this wealth is held by the rich and upper middle classes. This paper documents the changes in the Italian household sector’s financial wealth over the past two decades, by constructing the matrix of bilateral financial sectoral exposures. Households became increasingly exposed to the financial sector, which in turn was exposed to the highly indebted real and government sectors. The paper then simulates different financial shocks to gauge the ability of the household sector to absorb losses. Simple illustrative calculations are presented for a fall in the value of government bonds as well as for bank bail-ins versus bailouts.

The Measurement and Macro-Relevance of Corruption: A Big Data Approach
Description: Corruption is macro-relevant for many countries, but is often hidden, making measurement of it—and its effects—inherently difficult. Existing indicators suffer from several weaknesses, including a lack of time variation due to the sticky nature of perception-based measures, reliance on a limited pool of experts, and an inability to distinguish between corruption and institutional capacity gaps. This paper attempts to address these limitations by leveraging news media coverage of corruption. We contribute to the literature by constructing the first big data, cross-country news flow indices of corruption (NIC) and anti-corruption (anti-NIC) by running country-specific search algorithms over more than 665 million international news articles. These indices correlate well with existing measures of corruption but offer additional richness in their time-series variation. Drawing on theory from the corporate finance and behavioral economics literature, we also test to what extent news about corruption and anti-corruption efforts affects economic agents’ assessments of corruption and, in turn, economic outcomes. We find that NIC shocks appear to negatively impact both financial (e.g., stock market returns and yield spreads) and real variables (e.g., growth), albeit with some country heterogeneity. On average, NIC shocks lower real per capita GDP growth by 3 percentage points over a two-year period, illustrating persistence in the effect of such shocks. Conversely, there is suggestive evidence that anti-NIC efforts appear to have a sustained positive macro impact only when paired with meaningful institutional strengthening, proxied by capacity development efforts.

Household Leverage and the Recession
Description: We evaluate and partially challenge the ‘household leverage’ view of the Great Recession. In the data, employment and consumption declined more in states where household debt declined more. We study a model where liquidity constraints amplify the response of consumption and employment to changes in debt. We estimate the model with Bayesian methods combining state and aggregate data. Changes in household credit limits explain 40 percent of the differential rise and fall of employment across states, but a small fraction of the aggregate employment decline in 2008-2010. Nevertheless, since household deleveraging was gradual, credit shocks greatly slowed the recovery.

Mitigation Policies for the Paris Agreement: An Assessment for G20 Countries
Description: Following submission of greenhouse gas (GHG) mitigation commitments or pledges (by 190 countries) for the 2015 Paris Agreement, policymakers are considering specific actions for their implementation. To help guide policy, it is helpful to have a quantitative framework for understanding: i) the main impacts (on GHGs, fiscal balances, the domestic environment, economic welfare, and distributional incidence) of emissions pricing; ii) trade-offs between pricing and other (commonly used) mitigation instruments; and iii) why/to what extent needed policies and their impacts differ across countries. This paper provides an illustrative sense of this information for G20 member countries (which account for about 80 percent of global emissions) under plausible (though inevitably uncertain) projections for future fuel use and price responsiveness. Quantitative results underscore the generally strong case for (comprehensive) pricing over other instruments, its small net costs or often net benefits (when domestic environmental gains are considered), but also the potentially wide dispersion (and hence inefficiency) in emissions prices implied by countries’ mitigation commitments.

Banking in a Steady State of Low Growth and Interest Rates
Description: A prolonged low-interest-rate environment presents a significant challenge to banks and is likely to entail major changes to their business models over the long-run. Lower returns to maturity transformation in the face of flatter yield curves and an inability to offer deposit rates significantly below zero combine to compress bank earnings in this environment. Smaller, deposit-funded, less diversified banks are hurt most, increasing consolidation pressures and reach-for-yield incentives, presenting new financial stability challenges.To the extent that such an economic environment reflects a new, steady-state with lower equilibrium growth driven by population aging and slower productivity growth, lower credit demand is likely to drive banking toward provision of fee-based, utility services.

Counting the Oil Money and the Elderly: Norway's Public Sector Balance Sheet
Description: Based on a permanent income analysis, Gagnon (2018) has prominently suggested that Norway has saved too much, thereby free-riding on the rest of the world for demand. Our public sector balance sheet analysis comes to the opposite conclusion, chiefly because it also accounts for future aging costs. Unsurprisingly, we find that Norway’s current assets exceed its liabilities by some 340 percent of mainland GDP. But its nonoil fiscal deficits have grown very large (to almost 8 percent of mainland GDP) and aging pressures are only commencing. Therefore, Norway’s intertemporal financial net worth (IFNW) is negative, at about -240 percent of mainland GDP. As IFNW represents an intertemporal budget constraint, this implies that Norway’s savings are likely insufficient to address aging costs without additional fiscal action.
