No, not really. Responding to lingering concerns about the reliability of SVARs, Christiano et al (NBER Macro Annual, 2006, "CEV") propose to combine OLS estimates of a VAR with a spectral estimate of long-run variance. In principle, this could help alleviate specification problems of SVARs in...

We assess quantitatively the effect of exogenous reductions in fertility on output per capita. Our simulation model allows for effects that run through schooling, the size and age structure of the population, capital accumulation, parental time input into child-rearing, and crowding of fixed...

Credit constraints that link a private agent’s debt to market-determined prices embody a credit externality that drives a wedge between competitive and constrained socially optimal equilibria, inducing private agents to overborrow. The externality arises because agents fail to internalize the...

Many economists believe that, while openness to trade increases average GDP growth rates, it also raises output volatility by exposing countries to terms-oftrade shocks. This view does not take into account that, as suggested by a recent strand of the financial fragility literature, commercial...

The paper describes boom-and-bust cycles within Hayek's framework of order and aims to provide an understanding of recurring crises in recent financial history. We argue that a boom-and-bust cycle is initiated by a displacement that lowers the degree of (ex-post) plan coherence (or order) in an...

Why are some financial crises associated with political crises and some are not? Does political instability cause financial fragility or the other way around? What are the implications of political distortions for policy in countries experiencing financial turmoil? This paper studies these and...

I provide a framework for understanding debt deleveraging in a group of _nancially integrated countries. During an episode of international deleveraging world consumption demand is depressed and the world interest rate is low, reecting a high propensity to save. If exchange rates are allowed to...

The aim of this paper is to understand what a recession means for individual consumers, and to model in a life-cycle framework how individuals respond to recessions. Our focus is on the sharp increase in savings rates that have been observed in the current and recent recessions. We show...

This paper addresses the discussion between economic power and the power of politics with particular focus on financial markets. After general reflections about the economic basis of power, the paper discusses in a general equilibrium framework how financial innovations can lead to risk creation...
