Demand Collapse or Credit Crunch to Firms? Evidence from the World Bank's Financial Crisis Survey in Eastern Europe
(World Bank, Washington, DC, 2013-10)While there is a consensus that the 2008-2009 crisis was triggered by financial market disruptions in the United States, there is little agreement on whether the transmission of the crisis and the subsequent prolonged recession are due to credit factors or to a collapse of demand for goods and services. This paper assesses whether the primary effect of the global crisis on Eastern European firms took the form of an adverse demand shock or a credit crunch. Using a unique firm survey conducted by the World Bank in six Eastern European countries during the 2008-2009 financial crisis, the paper shows that the drop in demand for firms' products and services was overwhelmingly reported as the most damaging adverse effect of the crisis. Other "usual suspects," such as rising debt or reduced access to credit, are reported as minor. The paper also finds that the changes in firms' sales and installed capacity are significantly and robustly correlated with the demand sensitivity of the sector in which the firms operate. However, they are not robustly correlated with various proxies for firms' credit needs. -

Institutions and Firms' Return to Innovation : Evidence from the World Bank Enterprise Survey
(World Bank, Washington, DC, 2014-06)This paper poses a question: do firms in developing countries not innovate because they are unwilling to? The question moves away from the conventional focus on the obstacles (such as the lack of access to finance) that hinder firms' innovation ability. The World Bank's Enterprise Survey is used first to estimate the return to firms' innovation across many developing countries, in terms of sales and sales per worker. Then the return to innovation is compared across countries with different levels of institutional quality. In countries with lower institutional quality (specifically, rule of law, regulatory quality, property and patent right protection), the return to firms' innovation is lower. This suggests that poor institutional environment lowers firms' return to innovation and hence discourages them from investing in researching and adopting new products. -

Inflation and Indivisible Investment in Developing Economies
(World Bank Group, Washington, DC, 2014-07)In countries with limited access to finance, firms accumulate retained earnings to finance indivisible investment projects. McKinnon (1973) illustrates that when cash is used as a primary store of value, inflation may discourage investment as it increases the cost of accumulating retained earnings. This paper formalizes this argument in a dynamic framework and provides a simple calibration of the model that suggests sizable effects of inflation on investment. The mechanism is particularly relevant for small firms, as firms with lower cash flows must accumulate retained earnings for longer periods of time to meet the price of indivisible investment goods. Consistent with the model, empirical evidence suggests that inflation disproportionately reduces investment in small firms. -

The Cross-Country Magnitude and Determinants of Collateral Borrowing
(World Bank, Washington, DC, 2012-03)Using the World Bank Enterprise Survey covering 6,800 firms across 43 developing countries, this paper investigates the prevalence and determinants of collateralized borrowing. It focuses on the following two aspects: (1) whether firms' loans from financial institutions require collateral (the extensive margin) and (2) the collateral value relative to the loan value (the intensive margin). On the first aspect, it finds that collateral borrowing is prevalent. On average, 73 percent of loans from financial institutions require collateral. Firms that are small or sell domestically are significantly less likely to pledge collateral. Shorter loans and loans from non-bank financial institutions are also less often associated with collateral. On the second aspect, it finds that on average the loan value is at least 72 percent of the collateral value. The only robust and significant determinants of the collateral value are the type of assets used for collateral. The analysis also checks whether countries' income and institutions affect collateralized borrowing. It finds that firms in countries with higher income and better institutions and credit information are significantly less likely to pledge collateral. These factors, however, have little impact on collateral values. -

Valuation Effects with Transitory and Trend Productivity Shocks
(World Bank, Washington, DC, 2010-01)In the past two decades, cross-border portfolio holdings of a large variety of assets have risen sharply. This has created an important role for changes in asset prices of a country's external assets and liabilities (i.e. "valuation effects") in affecting the country's net foreign asset position. Valuation effects are commonly thought as stabilizing: they counteract current account movements and mitigate the impact of the current account on the country's net foreign asset position. This paper shows that whether valuation effects are stabilizing or not depends critically on the nature of underlying productivity shocks. In response to transitory shocks, valuation effects are stabilizing; but in response to trend shocks, such effects amplify the impact of the current account on the net foreign asset position. These contrasting results arise because optimally smoothing consumers respond differently to a transitory shock than to a trend shock to income. The results are consistent with the pattern of external imbalances between the United States and other G.7 countries since the 1990s. -

Euro Currency Risk and the Geography of Debt Flows to Peripheral European Monetary Union Members
(World Bank, Washington, DC, 2016-06)The pattern of debt flows to peripheral European Monetary Union members seems puzzling: they are mostly indirect and channeled through the large countries of the European Monetary Union. This paper examines to what extent the introduction of the euro and the elimination of the intra-area currency risk can explain this puzzle. A three-country dynamic stochastic general equilibrium framework with endogenous portfolio choice and two currencies is developed. In the equilibrium, the core members of the European Monetary Union emerge as the main group of lenders to the peripheral European Monetary Union members. Outside lenders are pushed from the periphery debt markets because of currency risk. The model generates a pattern of debt flows consistent with the data despite the absence of any exogenous frictions or market segmentations. -

Correcting Real Exchange Rate Misalignment : Conceptual and Practical Issues
(World Bank, Washington, DC, 2012-04)This paper studies the issue of real exchange rate misalignment and the difficulties in settling international real exchange rate disputes. The authors show theoretically that determining when a country should be sanctioned for real exchange rate "manipulations" is difficult: in some situations a country's real exchange rate targeting can be beneficial to other countries, while in others it is not. Regardless, it is difficult to establish whether a misaligned real exchange rate is intentionally manipulated rather than unintentionally caused by other policies or by various distortions in the economy. The paper continues by illustrating the difficulty in measuring real exchange rate misalignment, and provides a critical assessment of existing methodologies. It concludes by proposing a new method for measuring real exchange rate misalignment based on differences in marginal products between producers of tradable and non-tradable goods. -

Credit Constraints and the North-South Transmission of Crises
( 2010-08-01)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. -

Consumption Baskets and Currency Choice in International Borrowing
( 2011-11-01)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. -

Global Imbalances Before and After the Global Crisis
( 2010-06-01)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.
