Topics in Applied Macrodynamic Theory [PDF ebook] 

This book is about the study of topics in macro dynamics from an applied, empirical perspective. The modeling philosophy behind most of the chapters ofthisbookisof Keynesiannature, representinganattempttorevivethist- oreticalperspectiveontheworkingofthemacroeconomy. Themacroeconomic research pursued here is somewhat di?erent from the mainstream literature using the Dynamic Stochastic General Equilibrium (DSGE) approach as the basic modeling device. The main features of the latter are the assumptions of intertemporally optimizing agents, rational expectations, competitive m- kets and price mediated market clearing through su?ciently ?exible prices and wages. The New Keynesian approach to macroeconomics has, in the last decade or so, to a large extent, also adopted the DSGE framework, building on intertemporally optimizing agents and market clearing, but favoring more the concept of monopolistic competition, sticky wages and prices and nominal as well as real rigidities. An path breaking work of this type is the recent book by Woodford (2003). However, it is well known that the intertemporal approach of smoothly optimizing agents and fast adjustments in order to establish temporal or — tertemporal marginal conditions in the product market, labor and capital markets, has not been very successful to match certain stylized facts on those markets. A further de?ciency of those intertemporal decision models is that macroeconomic feedback e?ects—and their stabilizing or destabilizing impact on the macroeconomy—have rarely been considered in those models. Yet, those feedback mechanisms, relevant for the interaction of all three markets, have been theoretically and empirically explored since the 1930s.
