Bank Funding in Central, Eastern and South Eastern Europe Post Lehman: A “New Normal”?

Description: CESEE banks are reducing foreign funding sources in response to reduced external imbalances, reduced ability to tap international savings, banking group own strategies, initiatives by some regulators, and consistently with uncertainties surrounding the future of the banking union project. In the medium term, the global regulatory agenda and the high foreign presence and stock of FX loans exert opposite forces on rebalancing trends. In the long-term, any funding “new normal” will be determined by the future design of the EU financial architecture. In the meantime, limiting leverage, the use of FX loans and promoting aggregate saving through macro policies and capital market reforms will increase resilience against shocks going forward.

Investing Volatile Oil Revenues in Capital-Scarce Economies: An Application to Angola

Description: Natural resource revenues are an increasingly important financing source for public investment in many developing economies. Investing volatile resource revenues, however, may subject an economy to macroeconomic instability. This paper applies to Angola the fiscal framework developed in Berg et al. (forthcoming) that incorporates investment inefficiency and absorptive capacity constraints, often encountered in developing countries. The sustainable investing approach, which combines a stable fiscal regime with external savings, can convert resource wealth to development gains while maintaining economic stability. Stochastic simulations demonstrate how the framework can be used to inform allocations between capital spending and external savings when facing uncertain oil revenues. An overly aggressive investment scaling-up path could result in insufficient fiscal buffers when faced with negative oil price shocks. Consequently, investment progress can be interrupted, driving up the capital depreciation rate, undermining economic stability, and lowering the growth benefits of public investment.

Does Public-Sector Employment Fully Crowd Out Private-Sector Employment?

Description: We quantify the extent to which public-sector employment crowds out private-sector employment using specially assembled datasets for a large cross-section of developing and advanced countries, and discuss the implications for countries in the Middle East, North Africa, Caucasus and Central Asia. These countries simultaneously display high unemployment rates, low private-sector employment rates and high proportions of government-sector employment. Regressions of either private-sector employment rates or unemployment rates on two measures of public-sector employment point to full crowding out. This means that high rates of public employment, which incur substantial fiscal costs, have a large negative impact on private employment rates and do not reduce overall unemployment rates.

Potential Output and Output Gap in Central America, Panama and Dominican Republic

Description: Potential Output is a key factor for debt sustaintability analysis and for developing strategies for growth, but unfortunately it is an unobservable variable. Using three methodologies (production function, switching, and state-space), this paper computes potential output for CAPDR countries using annual data. Main findings are: i) CAPDR potential growth is about 4.4 percent while output gap volatility is about 1.9 percent; ii) The highest-potential growth country is Panama (6.5 percent) while the lowest-growth country is El Salvador (2.6 percent); iii) CAPDR business cycle is about eigth years.

Fiscal Sustainability, Public Investment, and Growth in Natural Resource-Rich, Low-Income Countries: The Case of Cameroon

Description: This paper assesses the implications of the use of oil revenue for public investment on growth and fiscal sustainability in Cameroon. We develop a dynamic stochastic general equilibrium model to analyze the effects of such investment on growth and on the path of key fiscal indicators, such as the non-oil primary deficit and public debt. Policy scenarios show that Cameroon’s large infrastructural needs and relatively low current debt levels could justify a temporary deviation from traditional policy advice that suggests saving part of the oil revenue to smooth expenditure over time. Model simulations show that a relatively high degree of efficiency of public investment is needed for scaled-up public investment to make a significant contribution to growth, while maintaining fiscal sustainability.

Bank Leverage and Monetary Policy's Risk-Taking Channel: Evidence from the United States

Description: We present evidence of a risk-taking channel of monetary policy for the U.S. banking system. We use confidential data on the internal ratings of U.S. banks on loans to businesses over the period 1997 to 2011 from the Federal Reserve’s survey of terms of business lending. We find that ex-ante risk taking by banks (as measured by the risk rating of the bank’s loan portfolio) is negatively associated with increases in short-term policy interest rates. This relationship is less pronounced for banks with relatively low capital or during periods when banks’ capital erodes, such as episodes of financial and economic distress. These results contribute to the ongoing debate on the role of monetary policy in financial stability and suggest that monetary policy has a bearing on the riskiness of banks and financial stability more generally.

Risk Exposures and Financial Spillovers in Tranquil and Crisis Times: Bank-Level Evidence

Description: For a sample of 83 financial institutions during 2003–2011, this paper attempts to answer three questions: first, what is the evolution of banks’ stock price exposure to country-level and global risk factors as approximated by equity indices; second, which bank-specific characteristics explain these risk exposures; third, are there clusters of banks with equity price linkages beyond market risk factors. The paper finds a rise in sensitivities to both country and global risk factors in 2011, although on average to levels still below those of the subprime crisis. The average sensitivity to European risk, specifically, has been steadily rising since 2008. Banks that are reliant on wholesale funding, have weaker capital levels and low valuations, and higher exposures to crisis countries are found to be the most vulnerable to shocks. The analysis of bank-to-bank linkages suggests that any “globalization” of the euro area crisis is likely to be channelled through U.K. and U.S. banks, with little evidence of direct spillover effects to other regions.

Fiscal Policy and Lending Relationships

Description: This paper studies how fiscal policy affects loan market conditions in the US. First, it conducts a Structural Vector-Autoregression analysis showing that the bank spread responds negatively to an expansionary government spending shock, while lending increases. Second, it illustrates that these results are mimicked by a Dynamic Stochastic General Equilibrium model where the bank spread is endogenized via the inclusion of a banking sector exploiting lending relationships. Third, it shows that lending relationships represent a friction that generates a financial accelerator effect in the transmission of the fiscal shock.

The Comovement in Commodity Prices: Sources and Implications

Description: We present a simple macroeconomic model with a continuum of primary commodities used in the production of the final good, such that the real prices of commodities have a factor structure. One factor captures the combined contribution of all aggregate shocks which have no direct effects on commodity markets other than through general equilibrium effects on output, while other factors represent direct commodity shocks. Thus, the factor structure provides a decomposition of underlying structural shocks. The theory also provides guidance on how empirical factors can be rotated to identify the structural factors. We apply factor analysis and the identification conditions implied by the model to a cross-section of real non-energy commodity prices. The theoretical restrictions implied by the model are consistent with the data and thus yield a structural interpretation of the common factors in commodity prices. The analysis suggests that commodity-related shocks have generally played a limited role in global business cycle fluctuations.

Inclusive Growth: An Application of the Social Opportunity Function to Selected African Countries

Description: The inclusiveness of growth depends on the extent of access to economic and social opportunities. This paper applies the concept of social opportunity function to ascertain the inclusiveness of growth episodes in selected African countries. Premised on the concept of social welfare function, inclusive growth is associated with increased average opportunities available to the population and improvement in their distribution. The paper establishes that the high growth episodes in the last decade in the selected countries came with increased average opportunities in education and health; but distribution of such opportunities varied across countries, depending on the country-specific policies underpining the growth episodes.
