We show how to use a simple perturbation method to solve non-linear rational expectation models. Drawing from the applied mathematics literature we propose a method consisting of series expansions of the non-linear system around a known solution. The variables are represented in terms of their...

We characterize the Laffer curves for labor taxation and capital income taxation quantitatively for the US, the EU-14 and individual European countries by comparing the balanced growth paths of a neoclassical growth model featuring ”constant Frisch elasticity” (CFE) preferences. We derive...

We compute average mark-ups as a measure of market power throughout time and study their interaction with fiscal policy and macroeconomic variables in a VAR framework. From impulse-response functions the results, with annual data for a set of 14 OECD countries covering the period 1970-2007, show...

Phenomena such as the Great Moderation have increased the attention of macro-economists towards models where shock processes are not (log-)normal. This paper studies a class of discrete-time rational expectations models where the variance of exogenous innovations is subject to stochastic regime...

This paper examplifies in a simple general equilibrium model the important role played by the monetary policy when there are strategic interactions bearing on nominal variables. It shows that the common notion of money neutrality is misleading in this context. Indeed, linear homogeneity in the...

This paper reviews the recent literature on monetary policy rules. We exposit the monetary policy design problem within a simple baseline theoretical framework. We then consider the implications of adding various real world complications. Among other things, we show that the optimal policy...

Unemployment in the big continental European economies like France and Germany has been substantially increasing since the mid 1970s. So far it has been difficult to empirically explain the increase in unemployment in these countries via changes in supposedly employment unfriendly institutions...

This paper tests “Bad Policy” Hypothesis which refers to the Great Moderation in the US. We examine this hypothesis by simulating model based impulse response functions for the both pre-Volcker period and post 1982 period. Deriving and simulating standard New Keynesian DSGE Model explicitly,...

We focus on the political economy question of how incentives to reform are likely to be affected under the unique policy regime provided by the EMU. We develop the analysis using an extended ins & outs Barro-Gordon model of inflation and public expenditure within a framework where labour market...

RESUMENEn el análisis económico se deben contemplar variables que generan un fuerte impacto en la coyuntura nacional y los mercados financieros. Dentro de las variables que generan este efecto se deben tener en cuenta las reguladas por el Banco Central de un país.En Colombia, el Banco de la...
