The initial government debt-to-GDP ratio and the government's commitment play a pivotal role in determining the welfare-optimal speed of fiscal consolidation in the management of a debt crisis. Under commitment, for low or moderate initial government debt-to-GPD ratios, the optimal consolidation...

We analyse the effects of a government spending expansion in a DSGE model with Mortensen-Pissarides labour market frictions, deep habits in private and public consumption, investment adjustment costs, a constant-elasticity-of-substitution (CES) production function, and adjustments in employment...

This paper presents the DIGNAR (Debt, Investment, Growth, and Natural Resources) model, which can be used to analyze the debt sustainability and macroeconomic effects of public investment plans in resource-abundant developing countries. DIGNAR is a dynamic, stochastic model of a small open...

Mozambique has great potential in natural gas reserves and if liquefied/commercialized the sum of taxes and other fiscal revenue from natural gas will, at its peak, reach roughly one third of total fiscal revenue. Recent developments in the natural resource sector have triggered a fresh round of...

We develop a optimal rules-based interpretation of the ''three pillars macroeconomic policy framework'': a combination of a freely floating exchange rate, an explicit target for inflation, and a mechanism than ensures a stable government debt-GDP ratio around a specified long run. We show how...

This paper reviews the literature on the informal economy, focusing first on empirical findings and then on existing approaches to modeling informality within both partial and general equilibrium environments. We concentrate on labour and credit markets, since these tend to be most affected by...

This paper proposes a fiscal policy framework we call Public Debt Targeting. The framework seeks to smooth primary spending over the business cycle while remaining consistent with public debt sustainability. Under the proposed framework, a government announces a commitment to a public debt band...

The output effects of 2009 fiscal expansions have been hotly debated. But the discussion of fiscal multipliers is even more relevant now that several European countries have had to quickly retract their stimulus measures in an effort to regain market confidence. Using regime-switching VARs we...
