Sustainable Real Exchange Rates in the New Eu Member States: What Did the Great Recession Change?
Description: The Great Recession affected export and import patterns in our sample countries, and these changes, coupled with a more volatile external environment, have profound impact on our estimates of real exchange rate misalignments and projections of sustainable real exchange rates. We find that real misalignments in several countries with pegged exchange rates and excessive external liabilities widened relative to earlier estimates. While countries with balanced net trade positions are expected to continue to experience appreciation during 2010-2014, several currencies are likely to require real depreciation to maintain sustainable net external debt. Our estimates point to somewhat larger disequilibria than those of IMF country teams, however, any estimates of equilibrium exchange rates are subject to sizable uncertainty.

Estimates of the Output Gap in Armenia with Applications to Monetary and Fiscal Policy
Description: This paper employs several econometric techniques to estimate the Armenian output gap. The findings indicate that the output gap is significantly positive in 2007 and 2008 and decreased dramatically in 2009. The paper uses these results to estimate a New Keynesian Phillips curve for Armenia, suggesting a significant role of the output gap and inflation expectations in determining current inflation. Finally, the underlying fiscal stance over the period 2000-09 is assessed by estimating the cyclically-adjusted fiscal balance. Most of Armenia’s fiscal deficit is found to be structural. Fiscal policy, while providing counter-cyclical support in 2009, has been largely pro-cyclical in the past.

Islamic Banking: How Has it Diffused?
Description: This paper investigates the determinants of the pattern of Islamic bank diffusion around the world using country-level data for 1992 - 2006. The analysis illustrates that income per capita, share of Muslims in the population and status as an oil producer are linked to the development of Islamic banking, as are economic integration with Middle Eastern countries and proximity to Islamic financial centers. Interest rates have a negative impact on Islamic banking, reflecting the implicit benchmark for Islamic banks. The quality of institutions does not matter, probably because the often higher hurdle set by Shariah law trumps the quality of local institutions in most countries. The 9/11 attacks were not important to the diffusion of Islamic banking; but they coincided with rising oil prices, which are a significant factor in the diffusion of Islamic banking. Islamic banks also appear to be complements to, rather than substitutes for, conventional banks.

Measuring Financial Barriers Among East African Community Countries
Description: This paper seeks to quantify existing financial barriers among East African Community (EAC) member countries based on analysis of each member country’s foreign exchange market. The primary contribution of this paper is the generation of an aggregate measure of financial barriers for the three relatively more advanced members (Kenya, Uganda, and Tanzania) using forward foreign exchange and interbank interest rate data. Its empirical results, which are corroborated by other evidence such as the levels of development of the financial markets and restrictions on capital flows, suggest that Kenya is the EAC’s most financially open country, followed by Uganda, and then Tanzania. The fact that the three countries exhibit different degrees of financial openness suggests that financial integration in the EAC region has a way to go.

The Effectiveness of Macroeconomic Commitment in Weak(er) Institutional Environments
Description: This paper analyzes the institutional conditions affecting the establishment and effectiveness of independent central banks and of budgetary institutions. It draws on the recent theory developed by North, Wallis and Weingast on the transition from a closed and fragile state to an open economic and political environment. The paper presents a composite indicator allowing for the identification of a country’s position along this transition path. The findings suggest that (i) while the establishment of autonomous central banks seems to be relatively independent from the broader institutional framework, sound budgetary institutions tend to be established in countries with higher levels of rule of law for the elites, and (ii) while central bank independence is effective in reducing inflation irrespective of a country’s position along the transition path, budget institutions seem to be most effective as a disciplining device in weak institutional environments.

The Dynamic Effects of Commodity Prices on Fiscal Performance in Latin America
Description: The recent boom and bust in commodity prices has raised concerns about the impact of volatile commodity prices on Latin American countries’ fiscal positions. Using a novel quarterly data set-which includes unique country-specific commodity price indices and a comprehensive measure of public expenditures-this paper analyzes the dynamic effects of commodity price fluctuations on fiscal revenues and expenditures for eight commodity-exporting Latin American countries. The results indicate that Latin American countries’ fiscal positions react strongly to shocks to commodity prices, yet there are marked differences across countries. Fiscal variables in Venezuela display the highest sensitivity to commodity price shocks, with expenditures reacting significantly more than revenues. At the other end of the spectrum, in Chile expenditure reacts very little to commodity price fluctuations, and the dynamic responses of its fiscal indicators are very similar to those seen in high-income commodity-exporting countries. This distinct behavior across countries may relate to institutional arrangements, which in some cases include the efficient application of fiscal rules amid political commitment and high standards of transparency.

Price of Risk: Recent Evidence From Large Financials
Description: Probability of default (PD) measures have been widely used in estimating potential losses of, and contagion among, large financial institutions. In a period of financial stress however, the existing methods to compute PDs and generate loss estimates that may vary significantly. This paper discusses three issues that should be taken into account in using PD-based methodologies for loss or contagion analyses: (i) the use of - risk-neutral probabilities - vs. -real-world probabilities; - (ii) the divergence between movements in credit and equity markets during periods of financial stress; and (iii) the assumption of stochastic vs. fixed recovery for financial institutions’ assets. All three elements have nontrivial implications for providing an accurate estimate of default probabilities and associated losses as inputs for setting policies related to large banks in distress.

Still Minding the Gap—Inflation Dynamics during Episodes of Persistent Large Output Gaps
Description: This paper studies inflation dynamics during 25 historical episodes in advanced economies where output remained well below potential for an extended period. We find that such episodes generally brought about significant disinflation, underpinned by weak labor markets, slowing wage growth, and, in many cases, falling oil prices. Indeed, inflation declined by about the same fraction of the initial inflation rate across episodes. That said, disinflation has tended to taper off at very low positive inflation rates, arguably reflecting downward nominal rigidities and well-anchored inflation expectations. Temporary inflation increases during episodes were, in turn, systematically related to currency depreciation or higher oil prices. Overall, the historical patterns suggest little upside inflation risk in advanced economies facing the prospect of persistent large output gaps.

Peaks, Spikes, and Barrels: Modeling Sharp Movements in Oil Prices
Description: Global oil markets were roiled by sharp price swings in 2008, and economists are still divided over the reasons for the unusual volatility. Those emphasizing fundamentals point to inelastic supply and demand curves, others view the phenomenon mostly as a result of financial investors flocking into commodity markets. This paper attempts to infer the strength of these competing hypotheses, using a simultaneous equation model that enables us to undertake a separate analysis of supply and demand factors. The model broadly captures both the surge and subsequent fall in prices, with a particularly strong impact of demand factors. The model captures a strong effect of a measure for global liquidity but does not find support for a speculative motive.

Fiscal Deficits, Public Debt, and Sovereign Bond Yields
Description: The recent sharp increase in fiscal deficits and government debt in many countries raises questions regarding their impact on long-term sovereign bond yields. While economic theory suggests that this impact is likely to be adverse, empirical results have been less clear cut, have generally ignored nonlinear effects of deficits and debt through some other key determinants of yields, and have been mostly confined to advanced economies. This paper reexamines the impact of fiscal deficits and public debt on long-term interest rates during 1980 - 2008, taking into account a wide range of country-specific factors, for a panel of 31 advanced and emerging market economies. It finds that higher deficits and public debt lead to a significant increase in long-term interest rates, with the precise magnitude dependent on initial fiscal, institutional and other structural conditions, as well as spillovers from global financial markets. Taking into account these factors suggests that large fiscal deficits and public debts are likely to put substantial upward pressures on sovereign bond yields in many advanced economies over the medium term.
