You have monthly data on gasoline prices in two cities—Vancouver and Toronto, for the years 2006–2010. In each month of each year, you observe the average price of gasoline in each city. Prices in Vancouver are usually higher than in Toronto, but the cities follow similar price trends, as prices rise in the summer months and respond similarly to demand and cost shocks. However, there are month-to-month fluctuations for various reasons.
Starting from January 1, 2008, Vancouver imposed a carbon tax which was expected to be reflected in higher gasoline prices. Explain how you would use a difference-in- differences framework to estimate the effect of the carbon tax. Carefully define any new variables you need based on the data provided. Then, write down a line of R code which will run the regression you need. Make sure you point out which regression coeffcient is the desired estimate.
