Wooldridge, Introductory Econometrics, Example 13.3 (the effect of a garbage incinerator's location on housing prices, with the data of Kiel and McClain 1995 on house sales in North Andover, Massachusetts, in 1978, before any rumours of the incinerator, and in 1981, when its construction began): pooling the two years, estimate by ordinary least squares a regression of the real house price (in 1978 dollars) on a dummy for 1981, a dummy for houses near the incinerator site, and the interaction of the two dummies. Report the coefficient on the interaction, the difference-in-differences estimate of the incinerator's effect on the price of nearby houses.
