This paper discusses a longstanding debate between two empirical approaches to macroeconomics: the econometrics program represented by Lawrence R. Klein, and the statistical economics program represented by Milton Friedman. I argue that the differences between these two approaches do not consist...

In this paper we review the evolution of macroeconomic modelling in a policy environment that took place over the past sixty years. We identify and characterize four generations of macro models. Particular attention is paid to the fourth generation - dynamic stochastic general equilibrium...

Several formal methods have been proposed to check identification in DSGE models via (i) the autocovariogram (Iskrev 2010), (ii) the spectral density (Komunjer and Ng 2011; Qu and Tkachenko 2012), or (iii) Bayesian indicators (Koop et al 2012). Even though all methods seem similar, there has been no...

Chari, Kehoe, and McGrattan (2007) (CKM) show that a large class of dynamic stochastic general equilibrium (DSGE) models with various frictions and shocks is observationally equivalent to a benchmark real business cycle (RBC) model with correlated 'wedges' in the RBC model's first-order...

Despite closing output gaps and tightening labor markets, inflation has remained low inthe euro area. Based on an augmented Phillips Curve framework, we find that thisphenomenon-sometimes attributed to low global inflation-has been primarily causedby a remarkable persistence of inflation,...

ARC(advance-retreat course) is an analysis theory and method which aims at socio-economic development issues. The main viewpoint of ARC theory is that the human can design and implement his economic strategies initiatively, and the environment synthesized by various objective factors has to...

Advance-Retreat Course (ARC) analysis is a theoretical analysis and method on socio- economic development. The main point of ARC is that any economic development behavior will face various pressure coming from environment, that is to say, human beings can actively devise and implement his own...
