A number of studies have documented a reduction in aggregate macroeconomic volatility beginning in the early 1980s. Using an empirical model of business cycles, we extend this line of research to state-level employment data and find significant heterogeneity in the timing and magnitude of the...

In this paper, we present a dynamic optimizing model that allows explicitly for imperfect substitutability between different financial assets. This is specified in a manner which captures Tobin's (1969) view that an expansion of one asset's supply affects both the yield on that asset and the...

Woodford (2007) argues that it is not appropriate to regard inflation in the steady state of New Keynesian models as determined by steady-state money growth. Woodford instead argues that the intercept term in the monetary authority's interest-rate policy rule determines steady-state inflation....

We study how the use of judgement or "add-factors" in macroeconomic forecasting may disturb the set of equilibrium outcomes when agents learn using recursive methods. We isolate conditions under which new phenomena, which we call exuberance equilibria, can exist in standard macroeconomic...

This paper discusses criticisms of the IS-LM framework in the macroeconomic literature of the last 40 years, and how the modern optimizing version of IS-LM addresses those criticisms. It is argued that many of the criticisms had been addressed by best-practice traditional IS-LM. Relative to this...

In this paper we provide international evidence on the issue of whether the optimizing IS equation is more stable than a backward-looking alternative. The international evidence consist of estimates of IS equations on quarterly data for the UK and Australia, both for the full sample of the last...

This paper proposes a solution method to solve linear difference models with lagged expectations. Variables with lagged expectations expand the model's state space greatly when N is large; and getting the system into a canonical form solvable by the traditional methods involves substantial manual...
