The steady application of Quantitative Easing (QE) has been followed by big and non-monotonic effects on international asset prices and international capital flows. These are difficult to explain in conventional models, but arise naturally in a model with collateral. This paper develops a...

Data demonstrate a correlation between demographic variables and financial cycle: an increase in the working-age population is associated with an expansion of the financial cycle, that is, credit growth and increased housing prices. To account for this stylized fact, this paper uses an OLG model...

This paper surveys the literature on the linkages between asset prices and macroeconomic outcomes. It focuses on three major questions. First, what are the basic theoretical linkages between asset prices and macroeconomic outcomes? Second, what is the empirical evidence supporting these...

This paper surveys the theoretical and empirical literature on the macroeconomic implications of financial imperfections. It focuses on two major channels through which financial imperfections can affect macroeconomic outcomes. The first channel, which operates through the demand side of finance...

This paper argues that changes in the propagation of idiosyncratic shocks along firm networks are important to understanding variations in asset returns. When calibrated to match key features of supplier-customer networks in the United States, an equilibrium model in which investors have...

When modelling the aggregate behavior of a population over long periods of time the standard approach is to consider the system as always being in equilibrium -- using averaging procedures based upon assumptions of rationality, utility-maximization and a high degree of independence amongst the...

Small firms continue to experience difficulty accessing adequate finance from formal external sources, notwithstanding many and varied institutional and policy initiatives introduced to address this seemingly perennial problem. Underpinning research indicates that information asymmetry is the...

One of the most often committed mistakes in economic reasoning is the supposition about continuity of economic processes. Yet what dominates in reality is the process of permanent changes which sometimes happen not in a linear but in a cascade way. It must be acknowledged that the capitalist...
