We analyze a monetary model with flexible labor supply, cash-inadvance constraints and seigniorage-financed government deficits. If the intertemporal elasticity of substitution of labor is greater than one, there are two steady states, one determinate and the other indeterminate. If the...

We consider the stability under adaptive learning of the complete set of solutions to the model x_i=beta(Ei*)(x_i+1) when |beat| 1. In addition to the fundamentals solution, the literature describes both finite-state Markov sunspot solutions and autoregressive solutions depending on an arbitrary...

We examine the nonlinear model x_t = E_t F(x_(t+1)). Markov SSEs exist near an indeterminate steady state, hat(x)=F(hat(x)), provided |F'(hat(x)| 1. Despite the importance of indeterminancy in macroeconomics, earlier results have not provided conditions for the existance of adaptively stable...

This paper sets up a sticky price model with external habit formations. It shows that the cross-correlation between output and interest rates as well as prices match the data well when there is habit formation. Consumption as well as output display a hump-shaped response to a positive monetary...

The Thanksgiving-Christmas holiday period is a major sales period for US retailers. Due to higher store traffic, tasks such as restocking shelves, handling customers’ questions and inquiries, running cash registers, cleaning, and bagging, become more urgent during holidays. As a result, the...

This paper studies the welfare consequences of exogenous variations in trend inflation in a New Keynesian economy. Consumption and leisure respond asymmetrically to a rise and a decline in trend inflation. As a result, an increase in the variance of shocks to the trend inflation process...

In the standard new Keynesian models, the optimal inflation rate is zero while the long-run inflation rate is non-zero positive in many countries. In this paper, we provide a new rationale for the non-zero trend inflation by utilizing the productivity gap between the intermediate-goods sector...

This paper presents a new mechanism through which monetary policy rules affect inflation persistence. When assuming that price reset hazard functions are not constant, backward-looking dynamics emerge in the NKPC. This new mechanism makes the traditional demand channel of monetary transmission...

This paper proposes a new econometric framework for estimating trend inflation and the slope of the Phillips curve with a regime-switching model. As a unique aspect of our approach, we assume regimes for the trend inflation at one-percent intervals, and estimate the probability of the trend...
