Abstract
In this paper, we examine the large shocks due to major economic or financial events that affected U.S. macroeconomic time series on the period 1860–1988, using outlier methodology. We show that most of these shocks have a temporary effect, showing that the U.S. macroeconomic time series experienced only few large permanent shifts in the long term. Most of these large shocks can be explained by major recessions and World War II as well as by monetary policy for the interest rate data. We also find that some economic events seem to have the same effect (immediate, transitory or permanent) on a number of macroeconomic series. Finally, we show that most macroeconomic time series do not seem inconsistent with a stochastic trend once we adjusted the data for these shocks.

Notes
A number of tests have been then developed to take into account a structural change in which the date of the break is a priori unknown (e.g., Zivot and Andrews 1992; Li 1995; Perron 1997; Sen 2004; Montañés et al. 2005). Vogelsang (1999), Perron and Rodriguez (2003) and Haldrup and Sansó (2008) suggested procedures for detecting multiple additive outliers in non-stationary time series.
See Appendix for selected studies on the estimated break dates in the Nelson–Plosser data set.
Indeed, except for the case of IO, the effects of outliers on the observed series are independent of the model.
From a simulation study, Chen and Liu (1993a) showed that their procedure performs well in terms of detecting outliers and obtaining unbiased parameter estimates.
See Tolvi (2001) for detailed discussion on the outlier detection procedure.
Andreou and Spanos (2003) showed that several estimated models by Nelson and Plosser (1982) could be misspecified, thus potentially biasing the performance of the unit root tests. Based on estimated models which are statistically adequate, they obtained different conclusions on the unit root hypothesis.
The non-linearity displays by the velocity can be explained by the presence of conditional heteroscedasticity.
Note that using the ARIMA(0,1,0) model to improve the power of level shift detection, no level shift is misidentified as innovative outliers.
Carlson (2005) suggested that real economic shocks were important determinants of the nationwide scope of the panic of 1893, however at the local level, liquidity concerns are found to be a more important trigger of bank panics. Temin (1998) believe that this contraction was rather monetary in nature, caused by flirting with devaluation.
Odell and Weidenmier (2004) analyzed links between the 1906 San Francisco earthquake and the panic of 1907. Note that this panic led to an important change in American financial architecture: the creation of the Federal Reserve System in 1913 as well as the National Monetary Commission in 1909.
Friedman and Schwartz (1963) argued that the 1920–1921 recession was quite severe, and the result of monetary restraint. Indeed, with the exception of the Great Depression, the decline in the monetary base from October 1920 to January 1922 was also the largest recorded in so short a period (Homer and Sylla 1991).
The outliers with the higher t-statistics for the interest rate are not located by the various tests as they investigated the Nelson–Plosser data set until 1970.
Darné and Diebolt (2004) studied the sensitivity of the unit root tests to the two-steps tests (correcting outliers and testing unit roots on outlier-adjusted data) from simulation experiments. They showed that this procedure does not affect the presence of unit roots in time series. Osborn et al. (1999) also used this procedure for testing seasonal unit roots.
Ng and Perron (2001) argued that the Akaike and Schwarz information criteria tend to select values of k that are generally too small for unit root tests to have good sizes.
Since the nominal GNP, the industrial production, the nominal wages and the velocity present some non-linearity we also used the non-linear unit root test proposed by Kapetanios et al. (2003). The unit root test developed by Seo (1999) is also applied on the velocity in which conditional heteroscedasticity has been detected. The results obtained from these unit root tests are identical with those from the efficient unit root tests.
From unit root tests with two structural breaks, at the 5% significance level, the null of unit root is rejected for six series (real (p.c.) and nominal GNP, industrial production, employment and unemployment) with the Lumsdaine–Papell test; for four series (industrial production, unemployment, real wage and money stock) with the Lee–Strazicich test; and for three series (real (p.c.) GNP and employment) with the Papell–Prodan test when considering model A in all series and model C for the real wages and the stock prices. Note that Papell and Prodan (2007) did not study the unemployment.
