In this paper we examine the features of the US wage Phillips curve over different time horizons analyzing the original Phillips’ specification on a scale-by-scale basis with data transformed by wavelet and band-pass filtering methods. Our results provide compelling evidence that the wage...

The application of wavelet analysis provides an orthogonal decomposition of a time series by time scale, thereby facilitating the decomposition of a data series into the sum of a structural component and a random error component. The structural components revealed by the wavelet analysis yield...

The information content of several interest rate spreads for future output growth is analyzed using wavelet analysis. The “scale-by-scale” regression analysis shows that standard indicators of the stance of monetary policy, such as the shape of the yield curve, the real federal funds rate,...

The literature on aggregate investment has recently shifted attention away from the stock market in favor of the bond market as a consequence of the disappointing empirical results of stock market's Q and the ability of credit spreads to forecast investment and output growth. In this paper we...

In this paper we revisit the evidence recently provided by Philippon (2009) about the relationship among bond market's Q, stock market's Q and aggregate investments for the US. Specifically, we analyze the stability of the relationship between aggregate investment and the two measures of Q...

This paper uses the structural change model and wavelet exploratory analysis to re-examine Tobin's q theory of investment. There are two main results. First, wavelet exploratory analysis provides a useful complementary approach to standard confirmatory statistical analysis. Specifically, using...

The goal of the paper consists in investigating if comovements in some selected time series are common to various countries and periods of time. To do so, we use 18 economic time series between 1960: I- 1998: IV for 17 European countries. We found "regularity" in terms of comovements and...

In this paper we apply the wavelets methodology to the analysis of the industrial production index of the G-7 countries between 1961:1-2005:5. The analysis is performed using a multi-scaling approach which decomposes the variance of the industrial production index and the covariance between the...
