This paper derives a general New Keynesian framework consistent with heterogeneous expectations by explicitly solving the micro-foundations underpinning the model. The resulting reduced form is analytically tractable and encompasses the representative rational agent benchmark as a special case....

This paper studies New Keynesian DSGE models with capital accumulation, different Taylor rules, and the potential for indeterminacy. It is shown that investment activity creates additional channels for monetary policy influence, which allow for the reconsideration of some of the key findings of...

We embed different instrument rules into a New Keynesian model for a small open economy that is augmented with technical trading in currency trade to examine the prerequisites for monetary policy. Specifically, this paper focuses on conditions for a determinate, least-squares learnable rational...

We embed an expectations-based optimal policy rule into a DSGE model for a small open economy that is augmented with trend extrapolation or chartism, which is a form of technical trading, in currency trade to examine the prerequisites for monetary policy. We find that a unique REE that is...

In this paper, we provide a set of sufficient conditions under which recursive competitive equilibrium exist and are unique for a large class of distorted dynamic equilibrium models with capital and elastic labor supply. We develop a monotone map approach to the problem. The class of economies...

This paper uses lattice programming methods along with the extension of Tarski's fixed point theorem due to Veinott (1992) and Zhou (1994) to establish sufficient conditions for existence of sequential symmetric Markov equilibrium in a large class of dynamic games. Our method is constructive and...

This paper considers a general class of nonlinear rational-expectations models in which policymakers seek to maximize an objective function that may be household expected utility. We show how to derive a target criterion that is 1) consistent with the model's structural equations, 2) strong...

State-dependent pricing models are now an operational framework for quantitative business cycle analysis. The analysis in Ball and Romer (1991), however, suggests that such models may be rife with multiple equilibria: in their static model price adjustment is always characterized by...

This paper considers a general class of nonlinear rational-expectations models in which policymakers seek to maximize an objective function that may be household expected utility. We show how to derive a target criterion that is 1) consistent with the model's structural equations, 2) strong...

In this paper we consider the entry and exit of RMS in a dynamic general equilibrium model with capital and a XED labour supply. At the firm level, there is a XED cost combined with increasing marginal cost, which gives a standard U-shaped cost curve with optimal firm size. At the aggregate...
