This paper proposes a new nonparametric test for conditional independence, which is based on the comparison of Bernstein copula densities using the Hellinger distance. The test is easy to implement because it does not involve a weighting function in the test statistic, and it can be applied in...

In this paper, we study the macroeconomic implications of sectoral heterogeneity and, in particular, heterogeneity in price setting, through the lens of a highly disaggregated multi-sector model. The model incorporates several realistic features and is estimated using a mix of aggregate and...

We consider the problem of testing whether the observations X1, ..., Xn of a time series are independent with unspecified (possibly nonidentical) distributions symmetric about a common known median. Various bounds on the distributions of serial correlation coefficients are proposed: exponential...

A chief goal of the Pigou cycle literature is to generate a boom in response to news of a future increase in productivity, and a bust if this improvement does not in fact take place. We nd that monetary policy can generate Pigou cycles in a two sector model with durables and non-durables, and...

This paper studies Tobin's proposition that inflation "greases" the wheels of the labor market. The analysis is carried out using a simple dynamic stochastic general equilibrium model with asymmetric wage adjustment costs. Optimal inflation is determined by a benevolent government that maximizes...

Statistical tests in vector autoregressive (VAR) models are typically based on large-sample approximations, involving the use of asymptotic distributions or bootstrap techniques. After documenting that such methods can be very misleading even with fairly large samples, especially when the number...

This paper constructs and estimates a sticky-price, Dynamic Stochastic General Equilibrium model with heterogenous production sectors. Sectors differ in price stickiness, capital-adjustment costs and production technology, and use output from each other as material and investment inputs...

Cet article cherche µa montrer l'interet de l'hypothµese de persistance des habitudes dans le comportement de consommation au regard des effets de la politique monetaire. Les mecanismes au coeur de certaines modµeles monetaires sont mis en exergue. Nous insistons alors, µa l'aide d'un...

This short paper employs individual voting records of the Monetary Policy Committee (MPC) of the Bank of England to study heterogeneity in policy preferences among committee members. The analysis is carried out using a simple generalization of the standard Neo Keynesian framework that allows...

In this paper, we study the macroeconomic implications of sectoral heterogeneity and, in particular, heterogeneity in price setting, through the lens of a highly disaggregated multi-sector model. The model incorporates several realistic features and is estimated using a mix of aggregate and...
