This paper argues that a specification of stochastic volatility commonly used to analyze the Great Moderation in DSGE models may not be appropriate, because the level of a process with this specification does not have conditional or unconditional moments. This is unfortunate because agents may...

The outburst of the 2008 global economic crisis sparked myriad criticism on mainstream neoclassical economic theory, which is blamed for not even have considered the possibility of the kind of collapse that the subprime mortgage meltdown unleashed. In this paper, it is argued that what happened...

This paper assesses the role of sovereign risk in explaining macroeconomic fluctuations in Turkey. We estimate two versions of a simple New Keynesian small open economy model on quarterly data for the period 1994Q3-2008Q2: A basic version and a version augmented by a default premium on...

The interaction of input-output networks with industrial structure affects the propagation and amplification of shocks, and is an important consideration for business cycle fluctuations. This paper shows how the extensive margin of entry and exit can greatly amplify idiosyncratic shocks in the...

We implement a new approach for the identification of news shocks about future technology. In a VAR featuring a measure of aggregate technology and several forward-looking variables, we identify the news shock as the shock orthogonal to technology innovations that best explains future variation...

The presence of i) stochastic trends, ii) deterministic trends, and/or iii) stochastic volatility in DSGE models may imply that the agents' objective functions attain infinite values. We say that such models do not have a valid micro foundation. The paper derives sufficient conditions which...

We show how to implement a competitive search equilibrium in a fully-specified DSGE environment. Competitive search, an equilibrium concept well-understood in labor market theory, offers an alternative to the commonly-used Nash bargaining in search-based macro models. Our simulation-based...

Emerging market financial crises during the late 1990s were marked by sudden withdrawals of funds by foreign creditors, resulting in production declines. The IMF favored positive signals to potential foreign creditors and initially recommended disciplined fiscal policy during the height of...

This paper deals with aggregate demand fluctuations and their price and output effects. Starting with a nominal income solution, a rule for determining the inflation and output growth effects is presented. Assigning alternative values to the key parameters of the suggested rule generates...
