Impact of Intra-European Trade Agreements, 1990-2005: Policy Implications for the Western Balkans and Ukraine
Description: The paper provides quantitative estimates of the impact of the European trade agreements on trade flows. It applies both static and dynamic panel estimation techniques. The results are useful to policymakers because new intra-European trade agreements are being negotiated. In the absence of a further expansion of the European Union, estimates of alternative policies may help to clarify the policy debate. The paper also illustrates that the performance of individual countries under the trade agreements can be explained in terms of their macroeconomic environment. The conclusions are likely to be relevant to the western Balkan countries and Ukraine.

Public Investment and Growth in the Eastern Caribbean
Description: This paper quantifies the effect of public investment on growth in the ECCU. The results, emerging from panel vector autoregressions, indicate that the return on public investment, as defined by Perreira (2000), is very likely negative. This means that the total change in real output induced by one EC dollar of public investment, due to its short-run impact on demand, or the longer-run impact on supply, is below one EC dollar. Public investment shocks also appear to appreciate the real exchange rate, suggesting that the short-run demand impact is larger than the long-run supply response.

Do Unit Value Export, Import, and Terms of Trade Indices Represent or Misrepresent Price Indices?
Description: Unit value export and import indices compiled from returns to customs authorities are often used as surrogates for price indices in the measurement of inflation transmission, terms of trade (effects), and to deflate import and export value series to derive volume series. Their widespread use is mainly due to their relatively low cost compared with establishment price surveys. This paper provides evidence of substantial bias in their representation of such price changes. Their continued use would mislead economic analysis. The paper considers the efficacy of alternative strategies for their improvement, and argues for a move to establishment-based price surveys.

Private-Sector Financial Liabilities in Advanced Economies: Is More Better?
Description: Advanced economies have been experiencing diverse developments in accumulation of financial liabilities by their household and corporate sectors since around 1995. Crosscountry- industry evidence indicates that the type of the financial system and the degree of labor market flexibility matter for the economic impact of expanded borrowings. Especially in countries with a more arm's length-based financial system and less rigid labor market, faster creation of corporate liabilities in recent years appears to have spurred growth of industries more reliant on external finance, and strengthened the development of growing industries. The findings suggest an association of recent increases in corporate borrowings with a reduction in costs of external finance and improvement in resource allocation-two supposed channels through which finance facilitates growth.

The Economics of Islamic Finance and Securitization
Description: Islamic lending transactions are governed by the precepts of the shariah, which bans interest and stipulates that income must be derived as return from entrepreneurial investment. Since Islamic finance is predicated on asset backing and specific credit participation in identified business risk, structuring shariah-compliant securitization seems straightforward. This paper explains the fundamental legal principles of Islamic finance, which includes the presentation of a valuation model that helps distil the essential economic characteristics of shariah-compliant synthetication of conventional finance. In addition to a brief review of the current state of market development, the examination of pertinent legal and economic implications of shariah compliance on the configuration of securitization transactions informs a discussion of the most salient benefits and drawbacks of Islamic securitization.

Exchange Rate Fluctuations and Output in Oil-Producing Countries: The Case of Iran
Description: Conventional wisdom states that currency depreciation in oil-producing countries are contractionary because demand effects, limited by the prevalence of oil exports priced in dollars, are more than offset by adverse supply effects. Iran, however, has experienced a rapid increase in non-oil exports in the last decade. Against this background, the paper tests whether the conventional wisdom still applies to Iran and concludes that the emergence of the non-oil export sector has made currency depreciation expansionary. The expansionary effect is particularly evident with respect to anticipated persistent depreciation in the long-run. Notwithstanding the varying effects of exchange rate fluctuations on the demand and supply sides of the economy, managing a flexible exchange rate gradually over time towards achieving stability in the real effective exchange rate may strike the necessary balance.

Global Imbalances and Financial Stability
Description: This paper discusses two opposing views on global imbalances: The "traditional view", which regards the imbalances as a threat to global economic and financial stability, and the "new paradigm" view, which considers that they are the natural consequence of economic and financial globalization. In terms of their policy implications, the traditional view focuses on monetary and fiscal policy decisions in the United States that need to be urgently reversed to avoid an abrupt unwinding of the imbalances involving a sell-off of dollar assets, a sharp increase in U.S. interest rates, and a hard landing for the global economy. By contrast, the new paradigm view considers that the imbalances will be resolved smoothly through the normal functioning of markets. The paper argues that an abrupt unwinding of imbalances is highly unlikely and advances a number of arguments in support of the new paradigm view.

Oil Shocks and External Balances
Description: This paper studies the effects of demand and supply shocks in the global crude oil market on several measures of countries' external balance, including the oil and non-oil trade balances, the current account, and changes in net foreign assets (NFA) during 1975-2004. We explicitly take a global perspective. In addition to the U.S., the Euro area and Japan, we consider a number of country groups including oil exporters and middle-income oil-importing economies. We find that the effect of oil shocks on the merchandise trade balance and the current account, which depending on the source of the shock can be large, depends critically on the response of the nonoil trade balance, and differs systematically between the U.S. and other oil importing countries. Using the Lane-Milesi-Ferretti NFA data set, we document the presence of large and systematic (if not always statistically significant) valuation effects in response to oil shocks, not only for the U.S., but also for other oil-importing economies and for oil exporters. Our estimates suggest that increased international financial integration will tend to cushion the effect of oil shocks on NFA positions for major oil exporters and the U.S., but may amplify it for other oil importers.

Old Curses, New Approaches? Fiscal Benchmarks for Oil-Producing Countries in Sub-Saharan Africa
Description: Buoyant oil prices have allowed oil-producing countries in sub-Saharan Africa (SSA OPCs) to increase oil exports and fiscal revenues, providing them with resources necessary to address the pressing social needs. To preclude another boom-bust cycle, this paper advocates the definition of a fiscal benchmark anchored in sustainability grounds, following Leigh- Olters (2006). The difference between current primary deficits and those that could be maintained after oil reserves are exhausted represent an indication of the degree to which fiscal positions will have to be adjusted-either gradually, while the overall balances remain in surplus, or abruptly, once oil revenues begin to dwindle.

Unconditional IMF Financial Support and Investor Moral Hazard
Description: This paper develops a simple model of international lending, and calibrates it to assess quantitatively the effects of contingent IMF financial support on the risk premiums and the crisis probability. In the model, the country borrows in both short and long term; market (coordination) failure triggers a liquidity run and inefficient default; and the IMF lends unconditionally under a preferred creditor status. The model shows that IMF financial support can help prevent a liquidity crisis without causing investor moral hazard by helping to remove a distortion-effectively subsidizing ex post short-term investors (who run for the exit) at the expense of long-term investors (who are locked in). The resulting equilibrium is welfare enhancing as both the country's borrowing costs and the likelihood of a crisis are lower. The calibration exercises suggest that IMF-induced investor moral hazard-which occurs if the IMF lends at a subsidized rate-is unlikely to be a concern in practice, particularly if the country's economic fundamentals are strong and short-term debt is small.
