This paper solves a second-best problem where a government has in particular to choose whether to tax financial inflows (capital controls) or not, and when. A multi-stage optimal control technique is used to this end. First, it is shown that it is optimal to switch in finite time from capital...

A few years after the publication of The General Theory, a number of economists began to present Keynes's model, identified with IS-LM, as a particular case of the Walrasian model. This view of IS-LM has often been rationalized by a basic syllogism: IS-LM was invented by John Hicks, Hicks was a...

In this paper, we compare, first, the impact of a windfall and a boom sectors on the economy of an oil exporting country and their welfare implications ; in a second step, we analyze how monetary policy should be conducted to insulate the economy from the main impact of these shocks, namely the...

A robust prediction across a wide range of open-economy macroeconomic models is that an unanticipated increase in public spending in a given country appreciates it currency in real terms. This result, however, contradicts the findings of a number of recent empirical studies, which instead...

This paper analyzes jointly optimal fiscal and monetary policies in a small open economy with capital and sticky prices. We allow for trade in consumption goods under perfect international risk sharing. We consider balanced-budget fiscal policies where authorities use distortionary taxes on...

This paper shows that internationalized production, modelled as trade in intermediate goods, challenges the standard result according to which exchange rate volatility insulates small open economies from external shocks. Movements of relative prices affect the economy through an additional...

This article explores the role of trend shocks in explaining the specificities of business cycles in Sub-Saharan African (SSA) countries using the methodology introduced by Aguiar and Gopinath (2007) [Emerging Market Business Cycles: The Cycle Is the Trend Journal of Political Economy 115(1)]....

In this paper, is show how procyclical capital flows originate boom-bust and sunspot episodes in a neoclassical growth model of a small, open economy. All markets are perfect, with the exception of the fact that some upper, endogenous limit is imposed on how much the economy can borrow from...

We study fiscal devaluation in a small-open economy with labor market search frictions. Our analysis shows the key role of both dimensions in shaping the optimal tax scheme. By reducing labor market distortions, the tax reform is welfare-improving. Yet, as it makes imports more expensive, fiscal...

This article examines the volatility dependence between the crude oil price and four US dollar exchange rates using both fractional cointegration and copula techniques. The former exploits the long memory behavior of the volatility processes to investigate whether they are tied through a common...
