Assessing Economic Liberalization Episodes: A Synthetic Control Approach

We use a transparent statistical methodology for data-driven case studies–the synthetic control method–to investigate the impact of economic liberalization on real GDP per capita in a worldwide sample of countries. Economic liberalization is measured by a widely used indicator that captures the scope of the market in the economy. The methodology compares the postliberalization GDP trajectory of treated economies with the trajectory of a combination of similar but untreated economies. We find that liberalizing the economy had a positive effect in most regions, but more recent liberalizations, in the 1990s and mainly in Africa, had no significant impact.

The Monetary Transmission Mechanism in Egypt

This paper examines the monetary transmission mechanism in Egypt against the background of the central banks intention to shift to inflation targeting. It first describes the changing transmission channels over the last decade. Second, the channels are evaluated in a VAR model. The exchange rate channel plays a strong role in propagating monetary shocks to output and prices. Most other channels (bank lending, asset price) are rather weak. The interest rate channel is underdeveloped but appears to be strengthening since the introduction of the interest corridor in 2005, which bodes well for adopting inflation targeting over the medium term.

Ghostbusting: Which Output Gap Measure Really Matters?

This paper investigates various output gap measures in a simple inflation forecasting framework. Reflecting the cyclical position of an economy, an (unobservable) output gap has important implications for economic analysis. I construct and compare common output gap measures for five European countries. Since output above potential reflects domestic inflationary pressures, including a gap could improve the accuracy of autoregressive inflation forecasting. This assertion is tested in a simple simulated out-of-sample forecasting exercise for the period 1990-2002. The main conclusions are that an output gap rarely provides useful information and that there is no single best output gap measure across countries.

Economies in Transition: How Important Is Trade Openness for Growth?

We investigate the effect of trade openness on economic growth in transition countries using a transparent statistical methodology that leads to data-driven case studies. In particular, we employ synthetic control methods in a panel of transition economies and compare GDP growth in treated (that is, open) countries with growth in a convex combination of similar but untreated (that is, closed) countries. We find that trade liberalization tends to have a positive effect on the pattern of real GDP per capita. One of our most robust results shows that making the transition without opening up to trade considerably hampers growth.

What Drives Stock Market Development in the Middle East and Central Asia-Institutions, Remittances, or Natural Resources?

In this paper, we assess the macroeconomic determinants of stock market capitalization in a panel of 17 countries in the Middle East and Central Asia, including both hydrocarbon-rich countries and economies without sizeable natural resource wealth. In addition to traditional variables, we include an institutional variable and remittances among the regressors. We find that (i) both institutions and remittances have a positive and significant impact on market capitalization; and (ii) both regressors matter, especially in countries without significant hydrocarbon sectors; whereas (iii) in resource-rich countries, stock market capitalization is mainly driven by the oil price.

Inflation Targeting in Georgia; Are We There Yet?

This paper evaluates whether Georgia is ready to adopt inflation targeting (IT), a monetary policy framework that several emerging markets have adopted recently. After reviewing selected prerequisites for successfully implementing IT, the paper focuses on whether one specific precondition is in place-an empirically stable monetary transmission mechanism. Building on a baseline VAR model, it presents several extensions to explore the various channels using causality tests, impulse responses, and variance decompositions. The paper finds that once the central bank overcomes some institutional and operational weaknesses and establishes a more reliable transmission mechanism, it could adopt IT over the medium term.

Trade Elasticities in the Middle East and Central Asia : What is the Role of Oil?

The analysis in this paper suggests that import and export volume elasticities are markedly lower in oil-exporting Middle East and Central Asian countries than in non-oil countries in the region. A key implication of this finding is that a real appreciation of the exchange rate in oil-exporting countries would achieve little in terms of expenditure switching: an appreciation does not boost imports and non-oil exports constitute only a small share of GDP and total trade in these countries. Therefore, while a real appreciation lowers the current account surplus of oil-exporting countries through valuation effects, the contribution to lowering global imbalances may be more limited.

In the Pipeline: Georgia`s Oil and Gas Transit Revenues

Starting in 2005, nontax revenue in Georgia is expected to rise significantly, in the form of transit fees for oil transported through the Baku-Tbilisi-Ceyhan Oil Pipeline. Transit fees for gas transported through the South Caucasus Pipeline are expected to start in 2007. This paper discusses (1) how much additional revenue can be expected, (2) prospects for monetizing gas that could be received as in-kind transit fees, in the light of pervasive nonpayment in the domestic gas sector, (3) the impact of these inflows on external competitiveness, (4) how to put in place appropriate reporting on these additional revenues, and (5) whether these inflows justify the creation of a special natural resource fund.

Analyzing Balance-Sheet Vulnerabilities in a Dollarized Economy: The Case of Georgia

Balance-sheet analysis (BSA) complements traditional flow-oriented macroeconomic analysis by gauging mismatches in aggregate and sectoral balance sheets of an economy. Enabled by recent progress in data availability, this paper applies BSA to Georgia, focusing on currency mismatches. In reviewing developments over the last five years, the paper finds that the still-high level of dollarization continues to create financial vulnerabilities, but that the overall level of currency mismatch has fallen and that liquidity problems are unlikely, in part owing to a strengthening of sectoral buffers, hedges, and insurance against shocks. Policy recommendations include accumulating reserves, strengthening securities markets, enhancing banking supervision, and maintaining a flexible exchange rate.

Push or Pull? The Determinants of Remittances to Egypt

Abstract Egypt is the recipient of sizeable remittance flows sent by the large number of Egyptians working outside their home country. In this paper, we analyze the relationship between these remittances and other macroeconomic variables, taking into account the nonstationary character of these time series. We find that both pull and push factors familiar from the capital flow literature are cointegrated with remittances, but our data do not allow us to clearly distinguish between altruism and other competing motives among the pull factors.
