Are Banks Really Lazy? Evidence from Middle East and North Africa
Description: We investigate whether low loan-to-deposit (LTD) ratios and high levels of reserve balances at the central bank (or holdings of government securities) are a reflection of policy-driven factors compared to commonly cited reasons of reluctance to lend or sometimes weak investment demand in uncertain environments. We examine changes to central bank (CB) balance sheet structures as well as commercial banks’ flow of funds over the period 2007–2012. First, Middle East and North Africa (MENA) CBs play an active role in view of their size that is very large with respect to their economies compared to CBs in advanced economies. Second, under exchange rate targeting, most MENA CB balance sheets are asset-driven, holding foreign exchange (FX) reserves to support the exchange rate policy and resulting in lower loan-to-deposit (LTD) ratios in the case of unsterilized increases in FX. Third, CB policy decisions seem to be accompanied by an increase in commercial bank reserve money balances, with ensuing reduction in the LTD. Finally, if governments meet their financing needs from the banking system—whether from commercial banks or by monetary financing—commercial bank balance sheets will tend to expand, resulting in lower LTD ratios. Our analysis suggests that government and CB actions may also drive the demand for and supply of credit, which are traditionally attributed to the behavior of banks and non-financial corporates and households only. The findings offer a different interpretation of changes in CB and banks’ balance sheets, with direct implications for LTD, calling to exercise caution in recommending policy action which aim at propping up LTD to ‘appropriate’ levels in an effort to reinvigorate credit following a downturn.

Fiscal Adjustment and Income Inequality: Sub-national Evidence from Brazil
Description: We combine state-level fiscal data with household survey data to assess the links between sub-national fiscal policy and income inequality in Brazil over the period 1995-2011. The results indicate that a tighter fiscal stance at the sub-national level is not associated with a deterioration in inequality measures. This finding contrasts with the conclusions of several papers in the burgeoning literature on the effects of fiscal consolidation on inequality using national data for OECD economies. In addition, we find that a tighter stance is typically positively associated with a measure of “shared prosperity”. Hence, our results caution against extrapolating policy implications of the literature focusing on advanced economies to other settings.

Time-Varying Neutral Interest Rate—The Case of Brazil
Description: Emerging markets have experienced a sizeable decline in their neutral real interest rates until recently. In this paper we try to identify the main factors that contributed to it, with a focus on Brazil. We estimate an interval for Brazil’s time-varying neutral rate based on a range of structural and econometric models. We assess the implications of incorrectly estimating a time-varying neutral rate using a small structural model with a simple monetary policy instrument rule. We find that policy prescriptions are very different when facing uncertainty of neutral rate and of output gap. Our result contrasts sharply with Orphanides (2002), suggesting that the best response to neutral rate uncertainty is to ensure policy remains highly sensitive to inflation and output variations.

With Great Power Comes Great Responsibility: Macroprudential Tools at Work in Canada
Description: The goal of this paper is to assess the effectiveness of the policy measures taken by Canadian authorities to address the housing boom. We find that the the last three rounds of macroprudential policies implemented since 2010 were associated with lower mortgage credit growth and house price growth. The international experience suggests that—in addition to tighter loan-to-value limits and shorter amortization periods—lower caps on the debt-to-income ratio and higher risk weights could be effective if the housing boom were to reignite. Over the medium term, the authorities could consider structural measures to further improve the soundness of housing finance.

Determinants of International Tourism
Description: The paper estimates the impact of macroeconomic supply- and demand-side determinants of tourism, one of the largest components of services exports globally, and the backbone of many smaller economies. It applies the gravity model to a large dataset comprising the full universe of bilateral tourism flows spanning over a decade. The results show that the gravity model explains tourism flows better than goods trade for equivalent specifications. The elasticity of tourism with respect to GDP of the origin (importing) country is lower than for goods trade. Tourism flows respond strongly to changes in the destination country’s real exchange rate, along both extensive (tourist arrivals) and intensive (duration of stay) margins. OECD countries generally exhibit higher elasticties with respect to economic variables (GDPs of the two economies, real exchange rate, bilateral trade) due to the larger share of business travel. Tourism to small islands is less sensitive to changes in the country’s real exchange rate, but more susceptible to the introduction/removal of direct flights.

Safe Havens, Feedback Loops, and Shock Propagation in Global Asset Prices
Description: We create a network of bilateral correlations of changes in sovereign bond yields and individual bank equity price changes since 2000. We extract some stylized facts from this network of asset price correlations and document the clear differences in asset price correlations between safe havens and non-safe havens: safe havens, as commonly defined, have higher sovereign-sovereign, bank-bank, and bank-sovereign correlations than nonsafe havens. In a simple shock propagation model, we illustrate how these higher correlations may turn safe havens into shock propagators. While we discuss safe havens as a group, we document how the US is in a category of its own, differing significantly from the other countries including Switzerland or Japan. Separately, we find that feedback loops amplify shocks, and those emanating from bank stress more than those emanating from sovereign stress.

Export Spillovers from Global Shocks for the Middle East and Central Asia
Description: This paper quantifies the effect of realized and potential global growth disappointments on export volumes from the Middle East, North Africa, the Caucasus, and Central Asia. Estimates of export elasticities with respect to trading partner GDP indicate non-oil export volumes are relatively responsive while service exports are less responsive. Downward revisions to global GDP growth for 2011–14 have impeded export performance, and the possibility of disappointing GDP growth in Europe and emerging markets presents further downside risks for exports. The Maghreb countries are particularly sensitive to developments in Europe, while CCA countries are more susceptible to growth in the BRICS.

European Productivity, Innovation and Competitiveness: The Case of Italy
Description: In Italy, price-based competitiveness measures are not always an accurate predictor of trade outcomes. This paper offers a more comprehensive assessment of Italian competitiveness, focusing on the role of innovation and the evolution of Italy’s export market share. Overall, Italy maintains a high-quality export mix, and the adaptability of small-scale specialized firms is still a source of strength. But, small firm size is becoming less of an asset, and even the most innovative sectors are weighed down by the structural barriers that have depressed productivity more broadly. Italy’s future competitiveness will depend on full implementation of a comprehensive structural-reform agenda.

SMEs’ Access to Finance in the Euro Area: What Helps or Hampers?
Description: The monetary transmission mechanism in the euro area has been adversely affected by the recent crises. Using survey data on thousands of euro area firms, we study factors that affect the access to finance of SMEs. We find that changes in bank funding costs and borrower leverage matter for firms’ access to finance. Increases in bank funding costs and borrowers’ debt-to-asset ratios are significantly and negatively associated with firms’ access to finance. The use of subsidies significantly improve access to finance of SMEs. Finally, access to finance is found to be positively related to firm size and firm age.

Hysteresis in Unemployment and Jobless Recoveries
Description: This paper develops and estimates a general equilibrium rational expectations model with search and multiple equilibria where aggregate shocks have a permanent effect on the unemployment rate. If agents' wealth decreases, the unemployment rate increases for a potentially indefinite period. This makes unemployment rate dynamics path dependent as in Blanchard and Summers (1987). I argue that this feature explains the persistence of the unemployment rate in the U.S. after the Great Recession and over the entire postwar period.
