The search for new ideas by profit-seeking firms and knowledge spillovers are well-known and fundamental sources of modern economic growth. This paper examines the implications of idea production and knowledge capital for monetary business cycles. We construct a sticky-wage model where workers...

We incorporate zero lower bound (ZLB) in monetary policy rule and asymmetric adjustment costs (AAC) in Rotemberg price setting mechanism and solve nonlinear New Keynesian DSGE models using projection method. And we estimate the latest Japanese economy between 1981:Q3 and 2015:Q1 from the...

The current account in developed countries is highly persistent and volatile in comparison to output growth. The standard intertemporal current account model with rational expectations (RE) fails to account for the observed current account dynamics together with persistent changes in...

This paper investigates the finite sample properties of the two-step estimators of dynamic factor models when unobservable common factors are estimated by the principal components methods in the first step. Effects of the number of individual series on the estimation of an auto-regressive model...

In this paper, we establish the consistency of the model selection criterion based on the quasi-marginal likelihood (QML) obtained from Laplace-type estimators. We consider cases in which parameters are strongly identified, weakly identified and partially identified. Our Monte Carlo results...

At the aggregate level, the evidence that deviations from purchasing power parity (PPP) are too persistent to be explained solely by nominal rigidities has long been a puzzle (Rogoff, 1996). Another puzzle from the micro price evidence of the law of one price (LOP), which is the basic building...

It has been claimed that the deviations from purchasing power parity are highly persistent and have quite long half-lives under the assumption of a linear adjustment of real exchange rates. However, inspired by trade cost models, nonlinear adjustment has been widely employed in recent empirical...

This paper considers the test of a unit root in transitional autoregressive models. In particular, we develop the asymptotic theory of the inf-t test for the null hypothesis of a unit root in a wide class of nonlinear autoregressive models having parameters that are identified only under the...

We examine whether the news shocks, as explored in Beaudry and Portier (2004), can be a major source of aggregate fluctuations. For this purpose, we extend a dynamic stochastic general equilibrium model, a la Christiano, Eichenbaum, and Evans (2005), by allowing news shocks on the total factor...

Volatile and persistent real exchange rates are observed not only in aggregate series but also in the individual good level data. Kehoe and Midrigan (2007) recently showed that, under a standard assumption on nominal price stickiness, empirical frequencies of micro price adjustment cannot...
