In this paper we use the covariate quantile autoregression approach to test whether consumption is a constant unit root process, as predicted by the permanent income hypothesis (PIH). We find evidence that at low quantiles of the conditional quantile function of consumption the persistence of...

The paper estimates export demand elasticities for a large number of developing and developed countries, using time-series techniques that account for the nonstationarity in the data. The average long-run price and income elasticities are found to be approximately -1 and 1.5, respectively. Thus,...

This paper derives a structural import demand equation and estimates it for a large number of countries, using recent time series techniques that address the problem of nonstationarity. Because the statistical properties of the different estimators have been derived only asymptotically,...

This paper develops a dynamic model of rational behavior under uncertainty, in which the agent maximizes the stream of future τ-quantile utilities, for τ ∈ (0, 1). That is, the agent has a quantile utility preference instead of the standard expected utility. Quantile preferences have useful...

Testing for the money illusion hypothesis in aggregate consumption function generally involves a regression model that projects real consumption onto nominal disposable income and a consumer price index. Price data are usually available at a monthly level, but consumption and income data are...

Reflecting the nature of economic decisions, the error correction mechanism (ECM) in the error-correction representation of a system of co-integrated variables may arise from forward-looking behavior. In such a case, the estimated ECM coefficients may misleadingly appear to be insignificant or...

Various methods are available to extract the “business cycle component” of a given time series variable. These methods may be derived as solutions to frequency extraction or signal extraction problems and differ in both their handling of trends and noise and their assumptions about the ideal...

Short-term analysis is generally performed with seasonally adjusted data from which further estimation of the business cycle is performed through well-known filters (HP, Baxter-King). However, the whole procedure is not fully consistent, because seasonal adjustment and trend-cycle estimation do...

This paper investigates the properties of the decomposition of a time series presented in a companion paper (Lacroix, (2008)). The procedure relies upon an extension of Beveridge-Nelson methodology. We focus on its empirical implementation and show the need for additional steps in order to...

In this paper, I propose a simple methodology for inferring the correlation between permanent and transitory shocks in unidentified unobserved components (UC) models, where the correlation is not identified. However, I show that there is an upper bound of the correlation implied from the...
