## Benderly and Zwick Data: Inflation, Growth and Stock Returns

### Description

Time series data, 1952–1982.

### Usage

    data("BenderlyZwick")

### Format

An annual multiple time series from 1952 to 1982 with 5 variables.

returns

  real annual returns on stocks, measured using the Ibbotson-Sinquefeld data base.

growth

  annual growth rate of output, measured by real GNP (from the given year to the next year).

inflation

  inflation rate, measured as growth of price rate (from December of the previous year to December of the present year).

growth2

  annual growth rate of real GNP as given by Baltagi.

inflation2

  inflation rate as given by Baltagi

### Source

The first three columns of the data are from Table 1 in Benderly and Zwick (1985). The remaining columns are taken from the online complements of Baltagi (2002). The first column is identical in both sources, the other two variables differ in their numeric values and additionally the growth series seems to be lagged differently. Baltagi (2002) states Lott and Ray (1992) as the source for his version of the data set.
