## Strike Durations

### Description

Data on the duration of strikes in US manufacturing industries, 1968–1976.

### Usage

data("StrikeDuration")

### Format

A data frame containing 62 observations on 2 variables for the period 1968–1976.

- duration
strike duration in days.

- uoutput
unanticipated output (a measure of unanticipated aggregate
industrial production net of seasonal and trend components).

### Details

The original data provided by Kennan (1985) are on a monthly basis, for the period 1968(1) through 1976(12). Greene (2003) only provides the June data for each year. Also, the duration for observation 36 is given as 3 by Greene while Kennan has 2. Here we use Greene's version.

`uoutput`

is the residual from a regression of the logarithm of industrial production in manufacturing on time, time squared, and monthly dummy variables.
