Monetary Policy and Relative Price Shocks in South Africa and Other Inflation Targeters
Description: When faced with a relative price shock, monetary authorities often aim to contain its second round effects on inflation while accepting first round effects. We analyze the experience of South Africa and other inflation targeters to explore whether and when this policy prescription implies changing the monetary policy stance. Inflation targeting central banks differ on how aggressively they typically react to relative price shocks, reflecting differences in resilience of underlying inflation to such shocks. An examination of individual policy decisions reveals the importance of the broader economic context in framing the responses to relative price shocks.

Is Monetary Policy Effective When Credit is Low?
Description: Monetary policy, at least in part, operates through both an interest rate and credit channel. The question arises, therefore, whether monetary policy is a less potent a device in affecting output and inflation in countries that have low levels of credit and where investment and consumption are not financed by borrowing in local currency. This paper employs a Panel Vector Auto Regression approach to examine the empirical evidence in a broad sample of emerging market countries. The data suggests that the effectiveness of changes in policy interest rates in influencing the path of inflation appear to be unrelated to the level of credit and that, instead, the willingness to allow exchange rate flexibility is a far more important determining factor.

New Shocks, Exchange Rates and Equity Prices
Description: We study exchange rate and equity price dynamics, in general equilibrium, in the presence of news shocks about future productivity and monetary policy. We identify a condition under which these asset prices become more volatile without affecting the volatility of the underlying processes-a positive correlation between news and current shocks. This condition also explains why persistent underlying processes generate volatile asset prices. In addition, we show that the correlation between exchange rate and equity returns depends critically on the currency denomination of the equity return and the monetary policy reaction to productivity shocks. The model we set up does well at matching second moments of exchange rate and equity returns for major floating currencies.

Cross-Border Coordination of Prudential Supervision and Deposit Guarantees
Description: The scramble to expand deposit guarantees in Europe in response to recent financial turmoil confirms that the on-going integration of European financial markets requires closer coordination of prudential policies and financial safety nets. We study the optimal design of prudential supervision and deposit guarantee regulations in a multi-country, integrated banking market such as the European Union, where policy-makers have either similar or asymmetric preferences regarding profitability and stability of the banking sector. The paper concludes with recommendations on policy priorities in this area.

A Small Quarterly Multi-Country Projection Model
Description: This is the second of a series of papers that are being written as part of a larger project to estimate a small quarterly Global Projection Model (GPM). The GPM project is designed to improve the toolkit for studying both own-country and cross-country linkages. In this paper, we estimate a small quarterly projection model of the US, Euro Area, and Japanese economies. The model is estimated with Bayesian techniques, which provide a very efficient way of imposing restrictions to produce both plausible dynamics and sensible forecasting properties. We show how the model can be used to construct efficient baseline forecasts that incorporate judgment imposed on the near-term outlook.

A Small Quarterly Projection Model of the US Economy
Description: This is the first of a series of papers that are being written as part of a project to estimate a small quarterly Global Projection Model (GPM). The GPM project is designed to improve the toolkit for studying both own-country and cross-country linkages. In this paper, we estimate a small quarterly projection model of the U.S. economy. The model is estimated with Bayesian techniques, which provide a very efficient way of imposing restrictions to produce both plausible dynamics and sensible forecasting properties. After developing a benchmark model without financial-real linkages, we introduce such linkages into the model and compare the results with and without linkages.

Analyzing Determinants of Inflation When There Are Data Limitation: The Case of Sierra Leone
Description: This paper examines the determinants of inflation in Sierra Leone using a structural vector autoregression (VAR) approach to help forecast inflation for operational purposes. Despite data limitations, the paper accurately models inflation in Sierra Leone. As economic theory predicts, domestic inflation is found to increase with higher oil prices, higher money supply, and nominal exchange rate depreciation. The paper then employs a historical decomposition approach to pinpoint the sources of a marked decline in inflation in 2006 and assesses its forecasting properties. Overall, the model serves as a useful addition to the toolkit for analyzing and forecasting inflation in countries with limited data availability.

Dynamic Factor Price Equalization & International Income Convergence
Description: The paper develops a tractable way to incorporate the micro structure of dual models of international trade into a standard class of dynamic open-economy macro models. In the process, it develops the concept of a dynamic factor price equalization set and an integrated intertemporal equilibrium. A number of results are obtained concerning trade, growth, and income convergence. Countries with higher capital/labor ratios may stay wealthier over time, both in the transition and in the new steady state. Real shocks in one country will be transmitted to the other country through the factor markets and traded goods prices.

Do Financial Sector Reforms Lead to Financial Development? Evidence from a New Dataset
Description: This paper studies whether the policies that, over the past decades, liberalized bankingsystems around the world have resulted in deeper credit markets. To measure banking sectorreforms we use a new index that tracks policy changes in five separate areas for 91 countriesover 1973-2005. We find that reforms have led to financial deepening, but only in countrieswith institutions that place checks and balances on political power. We interpret this asevidence of a complementarity between financial sector reforms and political institutions thatprotect property rights. Other country characteristics do not seem to significantly influencethe effect of banking reforms on financial development.

What is Really Good for Long-Term Growth? Lessons from a Binary Classification Tree (BCT) Approach
Description: Although the economic growth literature has come a long way since the Solow-Swan model of the fifties, there is still considerable debate on the "real' or "deep" determinants of growth. This paper revisits the question of what is really important for strong long-term growth by using a Binary Classification Tree approach, a nonparametric statistical technique that is not commonly used in the growth literature. A key strength of the method is that it recognizes that a combination of conditions can be instrumental in leading to a particular outcome, in this case strong growth. The paper finds that strong growth is a result of a complex set of interacting factors, rather than a particular set of variables such as institutions or geography, as is often cited in the literature. In particular, geographical luck and a favorable external environment, combined with trade openness and strong human capital are conducive to growth.
