This paper studies a general equilibrium model with multiple stages of production and sticky prices. Working through the input-output relations among industries at different stages and the timing of firms' pricing decisions, the model generates persistent fluctuations in both the inflation rate...

Growth mechanisms can significantly affect short run properties of monetary models. An equilibrium model with human capital accumulation through a learning-by-doing mechanism possesses both sustained inflation rigidity and persistent real responses in the presence of unexpected monetary shocks....

Models dealing with monetary policy are generally based on microfoundations that characterize the behaviour of representative agents (households and firms). To explain the representative consumer behaviour, it is generally assumed a utility function in which the intertemporal elasticity of...

The current financial crisis followed the “great moderation,” according to which the world’s central banks had gotten so good at countercyclical policy that the business cycle no longer existed. As more and more economists and media people became convinced that the risk of recessions had...

The standard new Keynesian monetary policy problem is, in its original presentation, a linear model. As a result, only three possibilities are admissible in terms of long term dynamics: the equilibrium may be a stable node, an unstable node or a saddle point. Fixed point stability (a stable...

In late 2008 and early 2009, there has been a serious deterioration in the economic outlook of political leaders, the media and many economic analysts. Comparisons of recent performance and the outlook have degenerated into comparisons with the Great Depression of the 1930s, suggesting that the...

The two episodes of food price surges in 2007 and 2011 have been particularly challenging for developing and emerging economies' central banks and have raised the question of how monetary authorities should react to such external relative price shocks. We develop a new-keynesian small...

This paper studies the effects of the European monetary unification on the volatility of the extensive margin of trade. First, we highlight empirical novel facts about the effects of monetary unification. We build country-level measures of the extensive margin of intra-EMU exports and describe...

Using a dynamic stochastic general equilibrium (DSGE) model that accounts for credit constraints, we study the effects of fiscal stimulus on the macroeconomy. We show that the presence of credit constraints results in larger fiscal multipliers than indicated by the standard DSGE models. If...

This paper suggests that non-fundamental component in asset prices is one of the drivers of financial and credit cycle. Presented model builds on the financial accelerator literature by including a stock market where limitedly-liable investors trade stocks of productive firms with stochastic...
