Bank Size, Market Concentration, and Bank Earnings Volatility in the US

We examine whether bank earnings volatility depends on bank size and the degree of concentration in the banking sector. Using quarterly data for non-investment banks in the United States for the period 2004Q1-2009Q4 and controlling for the quality of management, leverage, and diversification , we find that bank size reduces return volatility. The negative impact of bank size on bank earnings volatility decreases (in absolute terms) with market concentration. We also find that larger banks located in concentrated markets have experienced higher volatility during the recent financial crisis.

Distress in European Banks; An Analysis Basedon a New Dataset

The global financial crisis has highlighted the importance of early identification of weak banks: when problems are identified late, solutions are much more costly. Until recently, Europe has seen only a small number of outright bank failures, which made the estimation of early warning models for bank supervision very difficult. This paper presents a unique database of individual bank distress across the European Union from mid-1990s to 2008. Using this data set, we analyze the causes of banking distress in Europe. We identify a set of indicators and thresholds that can help to distinguish sound banks from those vulnerable to financial distress.

Oil Prices and Bank Profitability: Evidence from Major Oil-Exporting Countries in the Middle East and North Africa

This paper analyzes the relationship between oil price shocks and bank profitability. Using data on 145 banks in 11 oil-exporting MENA countries for 1994-2008, we test hypotheses of direct and indirect effects of oil price shocks on bank profitability. Our results indicate that oil price shocks have indirect effect on bank profitability, channeled through country-specific macroeconomic and institutional variables, while the direct effect is insignificant. Investment banks appear to be the most affected ones compared to Islamic and commercial banks. Our findings highlight systemic implications of oil price shocks on bank performance and underscore their importance for macroprudential regulation purposes in MENA countries.

Spatial spillovers in emerging market spreads

We use novel spatial econometrics techniques to explore spillovers in the sovereign bond market for 24 emerging economies during 1995-2010. The paper extends the previous literature focusing on spillover effects from advanced to emerging economies by analyzing transmission of shocks across emerging markets. After controlling for the impact of global factors, we find strong evidence of spillovers from both sovereign spreads and macroeconomic fundamentals in neighboring emerging economies. In addition to the geographical proximity, the channels of spatial transmission include trade and financial linkages. The results of the paper highlight the importance of accounting not only for spillovers from advanced economies to emerging markets, but also across emerging markets when analyzing sovereign spreads.

House Price Determinants in Selected Countries of the Former Soviet Union

This paper analyses the recent boom-bust cycle in the housing markets of selected Former Soviet Union (FSU) countries. The analysis is based on a newly constructed database on house prices in the FSU countries. Our estimations suggest that house price developments can largely be explained by the dynamics of fundamentals, such as GDP, remittances, and external financing. Overall, we find that deviations of house prices from their fundamentals have not been pronounced, suggesting that house price bubbles have not been formed in the FSU countries.

Foreign Investor Flows and Sovereign Bond Yields in Advanced Economies

Asset allocation decisions of international investors are at the core of capital flows. This paper explores the impact of these decisions on long-term government bond yields, using a quarterly investor base dataset for 22 advanced economies over 2004-2012. We find that a one percentage point increase in the share of government debt held by foreign investors can explain a 6-10 basis point reduction in long-term sovereign bond yields over the sample period. Accordingly, international flows to core advanced economy bond markets over 2008-12 are estimated to have reduced 10-year government bond yields by 40-65 basis points in Germany, 20-30 basis points in the U.K., and 35-60 basis points in the U.S. In contrast, foreign outflows are estimated to have raised 10-year government bond yields by 40-70 basis points in Italy and 110-180 basis points in Spain during the same period. Our results suggest that the divergence in long-term bond yields between core and periphery economies in the euro area may continue unless the “normalization” of macroeconomic determinants of bond yields is accompanied by a similar “normalization” of the foreign investor base.

Recovery Determinants of Distressed Banks: Regulators, Market Discipline, or the Environment?

Based on detailed regulatory intervention data among German banks during 1994-2008, we test if supervisory measures affect the likelihood and the timing of bank recovery. Severe regulatory measures increase both the likelihood of recovery and its duration while weak measures are insignificant. Results seem not to be driven by regulators directing measures to particularly bad banks. That is, our results remain intact when we exclude banks that eventually exit the market due to restructuring mergers or moratoria. More transparent publication requirements of public incorporation that indicate more exposure to market discipline are barely or not at all significant. Increasing earnings and cleaning credit portfolios are consistently of importance to increase recovery likelihood, whereas earnings growth accelerates the timing of recovery. Macroeconomic conditions also matter for bank recovery. Hence, concerted micro- and macro-prudential policies are key to facilitate distressed bank recovery.

Assessing the Variability of Tax Elasticities in Lithuania

This paper quantifies the variability of tax elasticities in Lithuania using two alternative methods: rolling regressions and pooled mean group estimator. The analysis is motivated by the systematic variation of tax revenues observed over the economic cycle in the recent past. Both methods confirm that tax elasticities moved with the cycle, which can be attributed to the procyclical tax compliance tendencies and structural composition effects across tax bases. Comparison of VAT revenue gaps across Baltic countries during the recent recovery suggests that tax revenues rebounded fastest in Estonia, followed by Lithuania and Latvia. Overall, the results of the study emphasize the importance of accounting for cyclical variation in tax elasticities when making short-term tax revenue projections.

Non-Linear Price Transmission Between Gasoline Prices and Crude Oil Prices

This paper analyses the adjustment of gasoline prices in response to shocks in crude oil prices. We show that the nature of the dynamic relationship between crude oil and gasoline prices changes in February 1999. For the pre-February 1999 and the post-February 1999 sample we estimate a Threshold Vector Error-Correction Model for US gasoline prices and crude oil prices. We find evidence for a threshold effect after February 1999. The results indicate that firms adjust prices only if the deviations from the long-term equilibrium between the price of crude oil and gasoline is large enough. However, it is not the crude oil price that adjusts but the price of gasoline. Unlike the pre-February 1999 period, short-run changes in both prices tend to reinforce each other driving up the price of crude oil and gasoline.

Correcting 'Beyond the Cycle:' Accounting for Asset Prices in Structural Fiscal Balances

This paper outlines an operational approach for incorporating the impact of asset price cycles in the calculation of structural fiscal balances (SFBs). The global financial crisis demonstrated that movements in asset prices can have an important fiscal impact. Failing to account for the fiscal impact of asset price cycles can encourage a pro-cyclical policy stance if temporarily high revenues are passed through into expenditures. In addition, over-estimating the SFB may lead to inadequate fiscal buffers when cyclical revenues eventually dissipate. The paper proposes an empirical approach to correct for asset prices and provides illustrative country results for selected OECD countries. We find that asset price cycles are imperfectly synchronized with the business cycle and are quantitatively significant with an average pre-crisis fiscal impact ranging from about ½ to 2 percent of GDP in the sample. For a number of countries, the pre-crisis fiscal impact of high asset prices was larger at about 4 percent of GDP.
