Does Money Matter for Inflation in Ghana?
Description: Money has only limited information value for future inflation in Ghana over a typical monetary policy implementation horizon (four to eight quarters). On the other hand, currency depreciation and demand pressures (as measured by the output gap) are shown to be important predictors of future price changes. Inflation inertia is high and inflation expectations are largely based on backward-looking information, suggesting that inflation expectations are not well anchored and hence more is needed to strengthen the credibility of Ghana's inflation-targeting regime.1

On the Stability of Money Demand in Ghana: A Bounds Testing Approach
Description: This paper adopts the bounds testing procedure developed by Pesaran et al. (2001) to test the stability of the long-run money demand for Ghana. The results provide strong evidence for the presence of a stable, well-identified long-run money demand during a period of substantial changes in the financial markets. The empirical evidence points to complex dynamics between money demand and its determinants while suggesting that deviations from the equilibrium are rather short-lived.1

Evaluating Designs for a Fiscal Rule in Bulgaria
Description: The enhanced Stability and Growth Pact calls on euro area members and aspirants to set boundaries to fiscal deficits through high-level legislation. A limit on the deficit, such as the deficit ceiling in Bulgaria's organic budget law, serves to protect solvency. The recent crisis clearly indicated that the key challenges are not only to contain the deficit but also to avoid a procyclical stance during upswings and to build a buffer for rainy days. Ideally, fiscal policymaking is guided by a fiscal rule that adapts through the economic cycle. This paper lays out the objectives of fiscal rules and analyzes how these objectives can be met in Bulgaria through either a growth-adjusted balance rule or an expenditure rule complemented by a deficit ceiling.

Assessing the Variability of Tax Elasticities in Lithuania
Description: 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.

The Design of Fiscal Adjustment Strategies in Botswana, Lesotho, Namibia, and Swaziland
Description: Botswana, Lesotho, Namibia, and Swaziland face the serious challenge of adjusting not only to lower Southern Africa Customs Union (SACU) transfers because of the global economic crisis, but also to a potential further decline over the medium term. This paper assesses options for the design of the needed fiscal consolidation. The choice among these options should be driven by (i) the impact on growth and (ii) the specificities of each country. Overall, a focus on government consumption cuts appears to minimize the negative impact on growth, and would be appropriate given the relatively large size of the public sector in each country.

Bank of Japan'S Monetary Easing Measures: Are they Powerful and Comprehensive?
Description: With policy rates near the zero bound, the Bank of Japan (BoJ) has introduced a series of unconventional monetary easing measures since late 2009 in response to lingering deflation and a weakening economy. These measures culminated in a new Asset Purchase Program under the Comprehensive Monetary Easing (CME) which differs from typical quantitative easing in other central banks by including purchases of risky asset in an effort to reduce term and risk premia. This note assesses the impact of monetary easing measures on financial markets using an event study approach. It finds that the BoJ's monetary easing measures has had a statistically significant impact on lowering bond yields and improving equity prices, but no notable impact on inflation expectations.

Can Emerging Market Central Banks Bail Out Banks? A+L4848 Cautionary Tale From Latin America
Description: This paper investigates whether developing and emerging market countries can implement monetary policies similar to those used by advanced countries during the recent global crisis - injecting significant amounts of money into the financial system without facing major short-run adverse macroeconomic repercussions. Using panel data techniques, the paper analyzes episodes of financial turmoil in 16 Latin America during 1995-2007. The results show that developing and emerging market countries should be cautious because injecting money on a large scale into the financial system may fuel further macroeconomic instability, increasing the chances of simultaneous currency crises.

Inflation Dynamics in Asia: Causes, Changes, and Spillovers From China
Description: The perception that Asia's inflation dynamics is driven by idiosyncratic supply shocks implies, as a corollary, that there is little scope for a policy reaction to a build-up of inflationary pressures. However, Asia's fast growth and integration over the last two decades suggest that the drivers of inflation may have changed, and that domestic demand pressures may now play a larger role than in the past. This paper presents a quantitative analysis of inflation dynamics in Asia using a Global VAR (GVAR) model, which explicitly incorporates the role of regional and global spillovers in driving Asia's inflation. Our results suggest that over the past two decades the main drivers of inflation in Asia have been monetary and supply shocks, but also that, in recent years, the contribution of these shocks has fallen, whereas demand-side pressures have started to emerge as an important contributor to inflation in Asia.

Do Commodity Futures Help Forecast Spot Prices?
Description: We assess the spot price forecasting performance of 10 commodity futures at various horizons up to two years and test whether this performance is affected by market conditions. We reject efficient markets based on in-sample tests but, out-of-sample, we find that the forecast from the futures market is hard to beat. We find that the forecasting performance of futures does not depend on the slope of the futures curve, in contrast to the predictions of well-known models of commodity markets. We also find futures' forecasting performance to be invariant to whether prices are in an upswing or downswing, casting doubt on aspersions that uninformed investors participating during bull markets impede the price discovery process.

Precautionary Savings in a Small Open Economy Revisited
Description: A common assumption in standard economic models is that agents are risk-averse and prudent, and it is often argued that prudence is necessary to generate precautionary savings. This paper shows that prudence is not necessary to generate precautionary savings in small open economy models with more than two periods. A new class of preferences, which enables the isolation of the effect of risk aversion on precautionary savings, is introduced. The effects of changes in risk aversion, interest rates, and persistence and volatility of shocks on average asset holdings are qualitatively identical to the ones observed for standard constant-elasticity-of-substitution preferences. These results show that the almost universal assertion in the literature - that only prudent consumers can generate positive levels of precautionary savings - is simply incorrect.
