Despite the voluminous literature on fiscal policy, very few papers focus on low-income countries (LICs). This paper develops a new-Keynesian small open economy model to show, analytically and through simulations, that some of the prevalent features of LICs—different types of financing including aid, the marginal efficiency of public investment, and the degree of home bias—play a key role in determining the effects of fiscal policy and related multipliers in these countries. External financing like aid increases the resource envelope of the economy, mitigating the private sector crowding out effects of government spending and pushing up the output multiplier. The same external financing, however, tends to appreciate the real exchange rate and as a result, traded output can respond quite negatively, reducing the overall output multiplier. Although capital scarcity implies high returns to public capital in LICs, declines in public investment efficiency can substantially dampen the output multiplier. Since LICs often import substantial amounts of goods, public investment may not be as effective in stimulating domestic production in the short run.

We construct unanticipated government spending shocks for 103 developing countries from 1990 to 2015 and study their effects on income distribution. We find that unanticipated fiscal consolidations lead to a long-lasting increase in income inequality, while fiscal expansions lower inequality. The results are robust to several measures of income distribution and size of the fiscal shocks, to an alternative identification strategy, across expansions and recessions and across country groups (low-income countries versus emerging markets). An additional contribution of the paper is the computation of the medium-term inequality multiplier. This is on average about 1 in our sample, meaning that a cumulative decrease in government spending of 1 percent of GDP over 5 years is associated with a cumulative increase in the Gini coefficient over the same period of about 1 percentage point. The multiplier is larger for total government expenditure than for public investment and consumption (with the former having larger effect), likely due to the redistributive role of transfers. Finally, we find that (unanticipated) fiscal consolidations lead to an increase in poverty.

This paper is the sixth in a series that examines macroeconomic developments and prospects in low-income countries (LICs). LICs are defined in this report as the countries eligible to PRGT facilities (69 countries). The first section of the paper discusses recent macroeconomic developments and trends across LICs. The second section estimates LICs’ financing needs up to 2025 to resume and accelerate their income convergence with advanced economies (AEs). It does this by estimating the additional financing that would enable LICs to step up spending response to COVID, including vaccination needs, while rebuilding or keeping external buffers to enhance resilience, and then the paper considers the financing needed to allow LICs to accelerate convergence with AEs. The paper then discusses a mix of financing options, including concessional financing from the international financial institutions, grants and loans from bilateral donors, private financing and debt operations, but also domestic reforms within LICs themselves as a key component to foster growth, enhance private investment, raise public revenues, and increase efficiency of spending.

This paper studies the effects of government spending under limited international capital mobility, as featured by most developing countries. While external financing of government debt mitigates the crowding-out effect, it generates real appreciation, which contracts traded output and lowers the fiscal multiplier in the short run. The decline of the multiplier is larger when facing debt-elastic country risk premia. Also, government spending is more expansionary with more home bias in government purchases, more sectoral rigidities, and a less flexible exchange rate. Whether the twin-deficit hypothesis holds depends crucially on the extent to which government deficits are financed externally.

What do we know about the output effects of fiscal policy in low income countries (LICs)? There are very few empirical studies on the subject. This paper fills this gap by estimating the output effects of government spending shocks in LICs. Our analysis—based on the local projection method—finds that the output effects in LICs are markedly lower than those in AEs and marginally smaller than those in EMs. We also find that in LICs, the output effects are larger (i) during recessions; (ii) under a fixed exchange rate regime; and/or (iii) with higher quality of institutions. Our analysis could not confirm any statistically significant output effect under floating exchange rate regimes. For the estimation of the output effects of fiscal spending shocks, it is thus important to consider the state of the economy and the country’s structural characteristics. Our results imply that the output costs of fiscal adjustment in LICs may not be as large as previously thought, especially if adopted outside of a recession, based on cutting public consumption, and accompanied by reform to enhance institutions.

The theoretical literature generally finds that government spending multipliers are bigger than unity in a low interest rate environment. Using a fully nonlinear New Keynesian model, we show that such big multipliers can decrease when 1) an initial debt-to-GDP ratio is higher, 2) tax burden is higher, 3) debt maturity is longer, and 4) monetary policy is more responsive to inflation. When monetary and fiscal policy regimes can switch, policy uncertainty also reduces spending multipliers. In particular, when higher inflation induces a rising probability to switch to a regime in which monetary policy actively controls inflation and fiscal policy raises future taxes to stabilize government debt, the multipliers can fall much below unity, especially with an initial high debt ratio. Our findings help reconcile the mixed empirical evidence on government spending effects with low interest rates.

After the break-up of the USSR, the former Soviet countries took different paths. While many of them face severe economic problems or have become only questionably democratic, Georgia’s socio-political development has become a relatively successful post-Soviet transition story. A deeper understanding of Georgia can offer insights that are also useful for other transitional and developing states. Many of the good governance implications of the research papers assembled in this volume are highly relevant to the broader Caucasus region and other post-Communist countries. The contributions deal with central issues pertinent to Georgian public policy, administration, and politics, as well as to Georgia’s ongoing struggle for independence and democracy. The collection illustrates a particularly revealing case in the comparative study of modern governance.

Private investment is the principal transmission channel through which fiscal policy affects growth in high-income countries. In low-income countries, governance and also other considerations suggest that the primary channel is factor productivity. Empirical results reported in this paper confirm this expectation: in low-income countries, factor productivity is some four times more effective than investment as a channel for increasing growth through fiscal policy. Although the private investment response to fiscal contraction may be minor, high-deficit, low-income countries can nonetheless benefit from a reduction in unsustainable fiscal deficits because of governance-related factor productivity responses that increase growth.
