We study the effects of debt-financed fiscal transfers in a general equilibrium, heterogeneous-agent model of the world economy. In the long run, increases in government debt anywhere raise the world interest rate and increase private wealth everywhere. In the short run, a country with a...

This paper evaluates optimal public investment and fiscal policy for countries characterized by limited tax and debt capacities. We study a non stochastic CRS endogenous growth model where public expenditure is an input in the production process, in countries where distortions and limited...

The Fiscal Theory of the Price Level (FTPL) is a promise to obtain price level determinacy even if the nominal interest rate is constant. The idea is that a unique current price level ensures that the present value government budget constraint holds. I establish that this idea hinges on the...

The ongoing demographic changes will bring about a substantial shift in the size and theage composition of the population, which will have significant impact on the global economy. Despite potentially grave consequences, demographic changes usually do not take center stage in many macroeconomic...

In the past decade, a new paradigm for fiscal and monetary policy analysis has emerged, combining the canonical macro model of income and wealth inequality with the New Keynesian model. These Heterogeneous-Agent New Keynesian ("HANK") models feature new transmission channels and allow for the...

This paper presents an empirical investigation of inflation dynamics in Libya over the period 1964–2010, using cointegration and error correction models. While inflation inertia is found to be a key determinant of consumer price inflation, the econometric results indicate that government...

The model developed here postulates that learning through experience plays a critical role in raising labor productivity over time, with three major consequences. First, the steady-state growth rate (of output) becomes endogenous and is influenced by government policies. Second, the speed of...

This paper examines the policy challenges a country faces when it wants to both reduce inflation and maintain a sustainable external position. Mundell's (1962) policy assignment framework suggests that these two goals may be mutually incompatible unless monetary and fiscal policies are properly...
