My dissertation consists of two independent essays on macroeconomic volatility and monetary economics respectively. The first essay explores the implications of imperfect information on macroeconomic volatility. It offers a micro-founded theory of time variation in the volatility of aggregate...

We analyze the standard New Keynesian economy adjusted by a financial intermediation sector, heterogenous, imperfect knowledge, and adaptive learning. We consider two groups of agents (i) private agents (households, firms, private banks) and (ii) the central bank who differ in their knowledge...

Monthly data on the inflation expectations of financial analysts in the Czech Republic exhibit a tendency for permanent bias and ineffectiveness which violates the rational expectations hypothesis assumed in macroeconomic models. This paper asks whether the surveyed data include any...

We advance the proposition that dynamic stochastic general equilibrium (DSGE) models should not only be estimated and evaluated with full information methods. These require that the complete system of equations be specified properly. Some limited information analysis, which focuses upon specific...

In this paper, I examine the role of monetary policy in a heterogeneous expectations environment. I use a New Keynesian business cycle model as the experiment laboratory. I assume that the central bank and private economic agents (households and producing rms) have imperfect and heterogeneous...
