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) Nguyen, Ha ; Qian, Rong

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) Nguyen, Ha ; Jaramillo, Patricio A.

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.
The Cross-Country Magnitude and Determinants of Collateral Borrowing

(World Bank, Washington, DC, 2012-03) Nguyen, Ha ; Qian, Rong

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) Nguyen, Ha

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.
Inflation and Indivisible Investment in Developing Economies

(World Bank Group, Washington, DC, 2014-07) Eden, Maya ; Nguyen, Ha

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.
Transitioning from Low-Income Growth to High-Income Growth : Is There a Middle Income Trap?

(World Bank Group, Washington, DC, 2014-11-01) Bulman, David ; Eden, Maya ; Nguyen, Ha

Is there a "middle income trap"? Theory suggests that the determinants of growth at low and high income levels may be different. If countries struggle to transition from growth strategies that are effective at low income levels to growth strategies that are effective at high income levels, they may stagnate at some middle income level; this phenomenon can be thought of as a "middle income trap." This paper does not find evidence for (unusual) stagnation at any particular middle income level. However, it does find evidence that the determinants of growth at low and high income levels differ. These findings suggest a mixed conclusion: middle-income countries may need to change growth strategies to transition smoothly to high-income growth strategies, but this can be done smoothly and does not imply the existence of a middle income trap.
Global Imbalances : Origins and Prospects

(Published by Oxford University Press on behalf of the World Bank, 2013-08-01) Servén, Luis ; Nguyen, Ha

This paper surveys the academic and policy debate on the origins of global imbalances, their prospects after the global crisis, and their policy implications. A conventional view of global imbalances considers them to primarily result from macroeconomic policies and cyclical forces that cause demand for goods to outstrip supply in the United States and other rich countries and that have the opposite effect in major emerging markets. An alternative view holds that global imbalances are the result of structural distortions and slow-changing factors that primarily affect assets markets. This paper reviews the analytical underpinnings of these two perspectives and the empirical evidence of their respective merits. The paper then assesses the outlook for global imbalances after the crisis, particularly in terms of policy action to reduce their magnitude. Policy intervention is warranted to the extent that the imbalances are driven by welfare-reducing distortions, but in this case, the primary target of policy intervention should be the distortions rather than the imbalances. Finally, the paper examines various forms of international spillovers that may call for multilateral action to limit global imbalances.
Do Capital Inflows Boost Growth in Developing Countries?: Evidence from Sub-Saharan Africa

(World Bank, Washington, DC, 2015-06) Calderon, Cesar ; Nguyen, Ha

This paper examines whether domestic output growth helps attract capital inflows and, in turn, capital inflows help boost output growth in a set of 38 Sub-Saharan African countries. Using a two-step approach to address reverse causality and omitted variable issues, the paper finds that output growth in countries in Sub-Saharan Africa does not attract capital inflows. However, aid and foreign direct investment inflows enhance growth, while sovereign debt inflows do not. A 1 percent increase in the level of real aid inflows raises growth of real output per capita by 0.022 percentage point. For foreign direct investment inflows, the figure is 0.002 percentage point.
The Great Recession and Job Loss Spillovers: Impact of Tradable Employment Shocks on Supporting Services

(World Bank, Washington, DC, 2016-01) Nguyen, Ha ; Rezaei, Shawheen ; Agarwal, Divya

This paper explores the spillover effects of job losses via input-output linkages during the Great Recession. Exploiting exogenous variation in tradable employment shocks across U.S. counties, the paper finds that job losses in a county’s tradable sectors cause further job losses in the county’s supporting services. For a given county, a 10 percent exogenous decline in tradable employment reduces supporting industries’ employment by 3.8 percent. In addition, a county’s regional supporting services are relatively less affected by its tradable job losses than its local supporting services are, which reinforces the argument that the spillovers are due to input-output linkages.
Unemployment and Mortality: Evidence from the Great Recession

(World Bank, Washington, DC, 2016-03) Nguyen, Ha ; Nguyen, Huong

Did unemployment in the Great Recession hurt people's health? The broad answer is no: job losses have statistically insignificant impacts on mortality. The exogenous sources of job losses in a U.S. county is the tradable job losses driven by external demand collapses during the Great Recession. The insignificant relationship holds for males and females, for all age groups, and for almost all categories of mortality. Three important exceptions are Alzheimer's, poisoning, and homicide.
