This paper studies the optimal long-run public intervention in a two-period OLG model where the probability of surviving the first period and the length of the second period can be influenced by distinct policies. While the optimal size of public intervention depends on the extra-productivity of...

We investigate the short-term effects of fiscal adjustment on economic activity in 20 OECD countries from 1970 to 2009. We compare two approaches: the traditional approach based on changes in cyclically adjusted primary balance (CAPB) and the narrative approach based on historical records....

This paper undertakes a normative investigation of the quantitative properties of optimal tax smoothing in a business cycle model with state contingent debt, capital-skill complementarity, endogenous skill formation and stochastic shocks to public consumption as well as total factor and capital...

Ramey (2011a) and others argue that increases in government spending associated with wars and military build-ups constitute a good instrument for measuring the macroeconomic effects of fiscal shocks. We argue that this instrument has two important drawbacks: the composition of government...

Fiscal policy has become quite controversial in the post-Keynesian era, the debate over the Obama stimulus package being a contentious recent example. Some pundits go so far as to take the position that macroeconomic theory has failed to meaningfully progress in terms of providing useful...

We investigate the macroeconomic effects of government spending shocks in Korea. We compare results obtained with two alternative approaches: the narrative approach and Structural Vector-Autoregressive model (SVAR). We propose a new methodology for identifying exogenous and unexpected fiscal...

Fiscal policy has become quite controversial in the post-Keynesian era, the debate over the Obama stimulus package being a contentious recent example. Some pundits go so far as to take the position that macroeconomic theory has failed to meaningfully progress in terms of providing useful...

We develop an endogenous growth model to quantify how permanent structural policy changes that enhance the fiscal policy mix, markets' functioning, and public institutions' quality affect long-term growth and welfare. The reforms include increased public investment, reduced market power through...

This paper explores the long-run impacts of tax policy in a two-country model of endogenous growth with variable labor supply. We focus on international spillover effects of tax reforms under alternative trade structures. It is shown that if the instantaneous utility function of the...

In this paper we test the AK model of growth with laboratory experiments. In each period, agents produce and trade output in a market, and allocate it to consumption and investment. The economy should experience a constant and positive rate of growth. We analyze two treatments differing from...
