The Landscape of Capital Flows to Low-Income Countries
Description: This paper reviews trends in capital flows and capital-like flows such as official grants and remittances to low-income countries over the period 1981-2006. The survey reveals a broadbased increase in such flows as a share of low-income country GDP across major regions, countries with differing commodity export composition, and countries with differing debt relief status. The increase in inflows is dominated by an increase in private sector inflows, mostly in the form of private transfers and foreign direct investment. Official sector inflows have remained comparatively constant as a share of low-income country GDP and even declined in the most recent years. The paper concludes with some tentative policy conclusions and has a discussion of data issues in the annexes.

External Linkages and Economic Growth in Colombia: Insights from A Bayesian VAR Model
Description: This paper investigates the sensitivity of Colombian GDP growth to the surroundingmacroeconomic environment. We estimate a Bayesian VAR model with informative steady-statepriors for the Colombian economy using quarterly data from 1995 to 2007. A variancedecomposition shows that world GDP growth and government spending are the most importantfactors, explaining roughly 17 and 16 percent of the variance in Colombian GDP growthrespectively. The model, which is shown to forecast well out-of-sample, can also be used toanalyse alternative scenarios. Generating both endogenous and conditional forecasts, we showthat the impact on Colombian GDP growth of a substantial downturn in world GDP growthwould be non-negligible but still a mild decline by historical standards.

Debt Sustainability under Catastrophic Risk: The Case for Government Budget Insurance
Description: Natural disasters are an important source of vulnerability in the Caribbean region. Despite being one of the more disaster-prone areas of the world, it has one of the lowest levels of insurance coverage. This paper examines the vulnerability of Belize's public finance to the occurrence of hurricanes and the potential impact of insurance instruments in reducing that vulnerability. The paper finds that catastrophic risk insurance significantly improves Belize's debt sustainability. In addition, the methodology employed makes it possible to estimate the appropriate level of insurance, which for the case of Belize is a maximum coverage of US$120 million per year.

International Reserve Trends in the South Caucasus and Central Asia Region
Description: In recent years, the South Caucasus and Central Asia countries (CCA-6) have received significant foreign exchange inflows. While a healthy reserve buffer is desirable to selfinsure against external crises, holding international reserves also involves costs. We analyze the adequacy of CCA-6 reserves using widely recognized rules of thumb, and simulate optimal reserve levels applying the Jeanne (2007) model. Both the adequacy measures and the model-based simulations indicate that, with the exception of Tajikistan, CCA-6 reserves had increased to broadly comfortable levels by 2006. More recently, reserve adequacy has been tested in Kazakhstan, which has been affected by the 2007 global liquidity crunch.

Terms of Trade Shocks and Economic Recovery
Description: This paper identifies factors that contribute to a fast recovery in growth after persistent negative terms of trade shocks, using a sample of 159 countries for 1970-2006. The results suggest that policies matter. Fast recoveries are fairly robustly related to real exchange rate depreciation and improvements in government stability and the institutional environment. A timely increase in aid may also support recovery.

Where Did All the Aid Go? An Empirical Analysis of Absorption and Spending
Description: This paper examines the macroeconomic usage of aid using panel data for a broad sample of aid-recipients. By definition an increase in aid must go toward a reduction in the current account balance (absorbed aid), an increase in capital outflows, or reserve accumulation. It is found that short-run absorption is typically very low, with much aid exiting through the capital account. Moreover, aid spending, defined in terms of the increase in government fiscal expenditures as a result of aid, is significantly greater than aid absorption, implying that aid systematically leads to an injection of domestic liquidity in recipient economies. The evidence here may help illuminate the rather weak link between aid and growth found in the literature. It reinforces the case for greater coordination between fiscal and monetary authorities in response to aid inflows.

External Tariff Liberalization in CARICOM: A Commodity-Level Analysis
Description: This paper estimates the impact of the tariff liberalization in four largest CARICOM countries (Barbados, Guyana, Jamaica, and Trinidad and Tobago) on their trade flows. I trace changes in the product-line imports from CARICOM and non-CARICOM countries against time and commodity-level variation in external tariffs. I find that in each country the reduction of the external tariff, which eroded preferences enjoyed by member imports, increased the ratio of imports from non-member countries to imports from member countries. In Trinidad and Tobago, the higher ratio was largely the result of non-member imports crowding out member imports. In the three other countries, the ratio increased mainly because of higher non-member imports; there is little evidence that tariff reductions had an impact on member imports. Findings suggest that in Trinidad and Tobago liberalization of the external tariff reversed some of the trade diversion effects of CARICOM.

Canadian Firm and Job Dynamics
Description: To understand better Canada's smooth reallocation of labor in response to the recent commodity price boom, but seemingly poor productivity performance, this paper examines job and firm dynamics in Canada relative to the United States. Overall, it finds that while Canada's labor market efficiency seems comparable to that of the United States, product market rigidities appear to be reducing Canada's capacity for creative destruction, hence undermining productivity growth.

Remittances and Institutions: Are Remittances a Curse?
Description: This paper addresses the complex and overlooked relationship between the receipt of workers' remittances and institutional quality in the recipient country. Using a simple model, we show how an increase in remittance inflows can lead to deterioration of institutional quality - specifically, to an increase in the share of funds diverted by the government for its own purposes. Empirical testing of this proposition is complicated by the likelihood of reverse causality. In a cross section of 111 countries we document a negative impact of the ratio of remittance inflows to GDP on domestic institutional quality, even after controlling for potential reverse causality. We find that a higher ratio of remittances to GDP is associated with lower indices of control of corruption, government effectiveness, and rule of law.

Where Did All the Borrowing Go? A Forensic Analysis of the U.S. External Position
Description: The deterioration in the U.S. net external position in recent years has been much smaller than the extensive net borrowing associated with large current account deficits would have suggested. This paper examines the sources of discrepancies between net borrowing and accumulation of net liabilities for the U.S. economy over the past 25 years. In particular, it highlights and quantifies the role played by net capital gains on the U.S. external portfolio and 'residual adjustments' in explaining this discrepancy. It discusses whether these 'residual adjustments' are likely to be originating from measurement errors in external assets and liabilities, financial flows, or capital gains, and explores the implications of these conjectures for the U.S. financial account and external position.
