The Connection between Wall Street and Main Street : Measurement and Implications for Monetary Policy

(World Bank, Washington, DC, 2013-10) Barattieri, Alessandro ; Eden, Maya ; Stevanovic, Dalibor

This paper proposes a measure of the extent to which a financial sector is connected to the real economy. The Measure of Connectedness is a measure of the composition of assets, namely the share of credit to the non-financial sectors over the total credit market instruments. The aggregate Measure of Connectedness for the United States declines by about 27 percent in the period 1952-2009. The authors suggest that this increase in disconnectedness between the financial sector and the real economy may have dampened the sensitivity of the real economy to monetary shocks. They present a stylized model that illustrates how interbank trading can reduce the sensitivity of lending to the entrepreneur's net worth, thereby dampening the credit channel transmission of monetary policy. The Measure of Connectedness is interacted with both a structural vector autoregressive model and a factor-augmented vector autoregressive model for the United States economy. The analysis establishes that the impulse responses to monetary policy shocks are dampened as the level of connection declines.
"Crowding in" and the Returns to Government Investment in Low-Income Countries

(World Bank, Washington, DC, 2014-02) Eden, Maya ; Kraay, Aart

This paper estimates the effect of government investment on private investment in a sample of 39 low-income countries. Fluctuations in a predetermined component of disbursements on loans from official creditors to developing country governments are used as an instrument for fluctuations in public investment. The analysis finds evidence of "crowding in": an extra dollar of government investment raises private investment by roughly two dollars, and output by 1.5 dollars. To understand the implications for the return to public investment, a CES production function with public and private capital as inputs is calibrated. For most countries in the sample, the returns to government investment exceed the world interest rate. However, for some countries that already have high government investment rates, the return to further investment is below the world interest rate.
Sovereign Defaults and Expropriations : Empirical Regularities

(World Bank, Washington, DC, 2012-10) Eden, Maya ; Kraay, Aart ; Qian, Rong

This paper uses a large cross-country dataset to empirically examine factors associated with sovereign defaults on external private creditors and expropriation of foreign direct investments in developing countries since the 1970s. In the long run, sovereign defaults and expropriations are likely to occur in the same countries. In the short run, however, these events are uncorrelated. Defaults are more likely to occur following periods of rapid debt accumulation, when growth is low, and in countries with weak policy performance, and defaults are not strongly persistent over time. In contrast, expropriations are not systematically related to the level of foreign direct investment, to growth, or to policy performance. Expropriations are however less likely under right-wing governments, and are strongly persistent over time. There is also little evidence that a history of recent defaults is associated with expropriations, and vice versa. The paper discusses the implications of these findings for models that emphasize retaliation as means for sustaining sovereign borrowing and foreign investment in equilibrium, as well as the implications for political risk insurance against the two types of events.
Excessive Financial Intermediation in a Model with Endogenous Liquidity

(World Bank, Washington, DC, 2012-05) Eden, Maya

Does an unregulated financial system absorb too many productive inputs? This paper studies this question in the context of a dynamic model with heterogeneous producers. In the absence of a financial system, the only way to purchase inputs is using internal funds. Producers are subject to idiosyncratic productivity shocks, and will decide to produce only if their productivity is high enough. Otherwise, they will hold money. A financial intermediation technology allows producers to purchase inputs in excess of their internal funds, by borrowing from unproductive agents. However, intermediation requires the use of costly monitoring services. In equilibrium, intermediation increases the money in circulation and raises nominal prices, thereby reducing the value of internal funds and making producers increasingly reliant on costly monitoring services. For this reason, society is better off when intermediation is restricted.
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.
Do Poor Countries Really Need More IT?: The Role of Relative Prices and Industrial Composition

(World Bank, Washington, DC, 2015-06) Eden, Maya ; Gaggl, Paul

Conventional wisdom suggests too little information and communication technologies (ICT) in poor countries. Indeed, within 70 countries at various levels of development, there is a positive relationship between income per capita and the capital share of ICT. While this regularity is consistent with explanations based on technology adoption lags and ICT-labor substitutability, there is little empirical support for these hypotheses. Instead, the paper establishes that this regularity can be fully accounted for by (a) relatively higher ICT prices in low-income countries and (b) industrial composition.
International Liquidity Rents

(World Bank, Washington, DC, 2013-05) Eden, Maya

This paper presents a model of global liquidity shortages. Liquid claims are enforceable promises that play a transaction role. Since developed economies have a comparative advantage in creating liquidity, they export liquid claims to emerging economies, resulting in a permanent current account deficit. This model suggests that unrestricted liquidity flows are (a) welfare reducing for emerging economies and (b) Pareto inefficient. The inefficiency results both from excessive investment for the purpose of creating collateral-backed liquid claims, and from excessive global fragility with respect to collateral shocks.
The Week

(World Bank, Washington, DC, 2016-03) Eden, Maya

Is a five-day workweek followed by a two-day weekend a socially optimal schedule? This paper presents a model in which labor productivity and the marginal utility of leisure evolve endogenously over the workweek. Labor productivity is shaped by two forces: restfulness, which decreases over the workweek, and memory, which improves over the workweek. The structural parameters of the model are disciplined using daily variation in electricity usage per worker. The results suggest that increases in the ratio of vacation to workdays lead to output losses. A calibration of the model suggests that a 2-3 day workweek followed by a 1 day weekend can increase welfare.
On the Welfare Implications of Automation

(World Bank, Washington, DC, 2015-11) Eden, Maya ; Gaggl, Paul

This paper establishes that the rise in the income share of information and communication technology accounts for half of the decline in labor income share in the United States. This decline can be decomposed into a sharp decline in the income share of “routine” labor—which is relatively more prone to automation—and a milder rise in the non-routine share. Quantitatively, this decomposition suggests large effects of information and communication technology on the income distribution within labor, but only moderate effects on the distribution of income between capital and labor. A production structure calibrated to match these trends suggests modest aggregate welfare gains from automation.
