Credit constraints and the north-south transmission of crises

Adverse shocks to rich countries often have a large and persistent negative impact on investment and output in developing countries. This paper examines a transmission mechanism that can account for this stylized fact. The mechanism is based on the existence of international financial frictions. Specifically, if a small, developing country has to collateralize its assets to borrow funds to invest, falling asset prices caused by a negative shock in an advanced economy worsen the developing country's collateral value and reduce its ability to borrow and reinvest. Hence, investment in the developing country declines, and international investors repatriate capital to the advanced country. As less capital now can be pledged as collateral, the developing country's credit constraint is further tightened, which leads to another round of decline in investment. This generates a downward spiral that may cause large output losses to the developing country. The mechanism finds empirical support in the 2008-2009 crisis data.Debt Markets,Emerging Markets,Economic Theory&Research,Investment and Investment Climate,Country Strategy&Performance

Consumption baskets and currency choice in international borrowing

Most emerging markets do not borrow much internationally in their own currency, although doing that has been argued as an attractive insurance mechanism. This phenomenon, commonly labeled"the original sin", has mostly been interpreted as evidence of the countries'inability to borrow in domestic currency from abroad. This paper provides a novel explanation for that phenomenon: not that countries are unable to borrow abroad in their currency, they might not need to do so. In the model, the small prevalence of external borrowing in domestic currency arises as an equilibrium outcome, despite the absence of exogenous frictions or limits on market participation. The equilibrium outcome is driven by the fact that domestic and foreign lenders have differential consumption baskets. In particular, a large part of domestic lenders'consumption basket is denominated in domestic currency whereas all of foreign lenders'is in dollars. A depreciation of domestic currency, which tends to occur in bad times, is therefore less harmful to domestic savers than to foreign investors. This makes domestic lenders require a lower premium than foreign lenders on domestic currency debt. For plausible calibrations, this consumption basket effect can induce foreign investors to pull out of the domestic currency debt market.Debt Markets,Currencies and Exchange Rates,Economic Theory&Research,Emerging Markets,Labor Policies

Global imbalances before and after the global crisis

This paper surveys the academic and policy debate on the roots of global imbalances, their role in the inception of the global crisis, and their prospects in its aftermath. The conventional view holds that global imbalances result primarily from unsustainably high demand for goods in the United States and other rich countries, and that their impending correction must involve major United States trade adjustment and dollar depreciation -- although recent literature argues that their extent may be dampened by financial adjustment effects. In contrast, an alternative view portrays global imbalances as the equilibrium result of asymmetries in world asset demand and supply. Absent changes in the deep determinants of these, global imbalances can persist. International capital flow patterns before and during the crisis lend support to the equilibrium view. The paper also examines different hypotheses proposed in the literature on the role of global imbalances in the generation and propagation of the financial crisis. On the whole, the evidence suggests that global imbalances were not among the major causes of the crisis. Lastly, the paper assesses alternative scenarios about the future of global imbalances, considering in particular their potential consequences for developing countries, and the policy measures that these might adopt to enhance their growth prospects in a changing global equilibrium.Currencies and Exchange Rates,Debt Markets,Emerging Markets,Economic Theory&Research,Investment and Investment Climate
