Now or Later? The Political Economy of Public Investment in Democracies
Description: This paper explores the impact of political and institutional variables on public investment. Working with a sample of 80 presidential and parliamentary democracies between 1975 and 2012, we find that the rate of growth of public investment is higher at the beginning of electoral cycles and decelerates thereafter. The peak in public investment growth occurs between 21 and 25 months before elections. Cabinet ideology and government fragmentation influence the size of investment booms. More parties in government are associated with smaller increases in public investment while left-wing cabinets are associated with higher sustained increases in investment. Stronger institutions help attenuate the impact of elections on investment, but available information is insufficient to draw definitive conclusions.

Institutions and Growth: a GMM/IV Panel VAR Approach
Description: Both sides of the institutions and growth debate have resorted largely to microeconometric techniques in testing hypotheses. In this paper, I build a panel structural vector autoregression (SVAR) model for a short panel of 119 countries over 10 years and find support for the institutions hypothesis. Controlling for individual fixed effects, I find that exogenous shocks to a proxy for institutional quality have a positive and statistically significant effect on GDP per capita. On average, a 1 percent shock in institutional quality leads to a peak 1.7 percent increase in GDP per capita after six years. Results are robust to using a different proxy for institutional quality. There are different dynamics for advanced economies and developing countries. This suggests diminishing returns to institutional quality improvements.

What Matters for Financial Development and Stability?
Description: This study aims to identify policies that influence the development of financial institutions as measured across three dimensions: depth, efficiency, and stability. Applying the concept of the financial possibility frontier, developed by Beck & Feyen (2013) and formalized by Barajas et al (2013a), we determine key policy variables affecting the gap between actual levels of development and benchmarks predicted by structural variables. Our dynamic panel estimation shows that inflation, trade openness, institutional quality, and banking crises significantly affect financial development. Our analysis also helps identify potential complementarities and trade-offs for policy makers, based on the effect of the policy variables across the different dimensions of financial development.

Fiscal Deficit and Public Debt in the Western Balkans: 15 Years of Economic Transition
Description: In this paper we analyze how Western Balkans public finances adapted to the boom-bust cycle. Large capital inflows into emerging European economies during the mid-2000s resulted in rapid economic growth and convergence to EU income levels. This also resulted in improved fiscal positions of most countries, on the back of strong revenue performance. Yet, since the onset of the global economic crisis, many countries have struggled to adjust to the new situation of lower external financing and lower growth.

Transforming Non-Renewable Resource Economies (NREs)
Description: This paper provides an empirical benchmarking of growth, productivity and export patterns for developing NREs against other low and middle income developing countries, to inform policy discussions and future analytical work. There is stark heterogeneity in the association of resource sector and overall growth outcomes, by commodity and degree of dependence. Over the long term, inter-sectoral growth dynamics have been more muted for NREs than other developing countries, especially at lower incomes. Despite productivity convergence in mining, as expected, productivity growth in manufacturing and services was generally lower in NREs. Exceptions are few, in East Asia and the CIS area which experienced broad-based productivity growth. NRE product exports are more concentrated and relatively less complex, though we find increasingly diversified service export baskets. Technological progress and specialization in trade in services may offer diversification options for the future.

A Model for Monetary Policy Analysis in Uruguay
Description: Uruguay has recently reverted to a money targeting (MT) framework in the context of a disinflation strategy. We develop a quantitative model for monetary policy analysis incorporating money targets in the policy framework while also retaining a central role for interest rates in the transmission of policy. We use the model to show that tight financial conditions for a period may be necessary for inflation to converge to the middle of the target band. We also discuss various aspects of the MT framework. Two issues stand out. Excessive focus on hitting money targets can result in undesirable changes in the policy stance; while targets that incorporate elements of money demand forecasting are superior to targets that are excessively smooth or do not adjust for base effects.

Household Financial Access and Risk Sharing in Nigeria
Description: We examine the role of household financial access in determining the extent of risksharing in Nigeria using household-level panel data. We estimate changes in the response of consumption to shocks for households with formal and informal access to finance and those without, both for the country as a whole and for different regions. Our findings suggest that households with financial access who experience an unexpected negative income shock see consumption fall by 15 percentage points less than those without access. This result is mainly driven by households with informal financial access, and by household savings rather than borrowing. Regional variation in risk sharing tends to be significant, suggesting that financial inclusion efforts going forward should have a more regional focus.

Does Public Sector Inefficiency Constrain Firm Productivity: Evidence from Italian Provinces
Description: This paper studies the effect of public sector efficiency on firm productivity using data from more than 400,000 firms across Italy’s provinces. Exploiting the large heterogeneity in the efficiency of the public sector across Italian provinces and the intrinsic variation in the dependence of industries on the government, we find that public sector inefficiency significantly reduces the labor productivity of private sector firms. The results suggest that raising public sector efficiency could yield large economic benefits: if the efficiency in all provinces reached the frontier, output per employee for the average firm would increase by 9 percent.

Default Premium
Description: We re-assess the view that sovereigns with a history of default are charged only a small and/or short-lived premium on the interest rate warranted by observed fundamentals. Our reassessment uses a metric of such a “default premium” (DP) that is consistent with asymmetric information models and nests previous metrics, and applies it to a much broader dataset relative to earlier studies. We find a sizeable and persistent DP: in 1870-1938, it averaged 250 bps upon market re-entry, tapering to around 150 bps five years out; in 1970- 2011 the respective estimates are about 400 and 200 bps. We also find that: (i) these estimates are robust to many controls including on actual haircuts; (ii) the DP accounts for as much as 60% of the sovereign spread within five years of market re-entry; (iii) the DP rises with market exclusion spells. These findings help reconnect theory and evidence on why sovereign defaults are infrequent and earlier debt settlements are desirable.

Macroeconomic Challenges of Structural Transformation: Public Investment, Growth and Debt Sustainability in Sierra Leone
Description: This paper analyzes the link between public investment, economic growth and debt sustainability in Sierra Leone using an inter-temporal macroeconomic model. In the model, public capital improves the productive capacity of private capital, generating positive medium and long term effects to increases in public investment. The model application indicates that a large increase in public investment would have positive macroeconomic effects in the medium term. However, since there is no free lunch, rigidities in tax adjustment would entail unrealistic and unachievable adjustment in the current spending to cover recurrent costs and ensure debt sustainability. A more ambitious increase in public investment would entail more fiscal adjustment, particularly if external commercial loans are secured to complement the adjustment. The model simulations also emphasize the importance of improvements in the structural economic conditions to reap growth dividends. In addition, even if the macroeconomic implications of public investment scaling-up can be favorable in the long term under changes in certain structural conditions, downside risks such as terms of trade shifts and Ebola-induced productivity shortfall expose the country to increased risk of unsustainable debt dynamics. This underscores the need to remove bottlenecks to growth and maintain prudent borrowing policies.
