Personal Disposable Income and Spending on Imports

By , About.com Guide

As incomes rise, it is interesting to see whether people spend more of their new wealth on imports or if they spend their money in their home country. A simple linear model to determine the spending on imported goods is:

Yt = b1 + b2 * Xt Where:
Yt is expenditure on imported goods.
Xt is personal disposable income.

For an econometrics paper, you can see if this relationship holds in the United States. You can use monthly import/export data that be can downloaded at:

The data is in Microsoft Excel format, but you should be able to convert it to any econometrics program you'd like.

You should consider the following issues in your paper:

  • How strong is the relationship between personal disposable income and imports?
  • Does the value of imports from some country rise faster than imports from other countries?
  • Should you use import data from one country? How about combining data from several countries? Should import data from each country be a seperate variable?
  • If extra variables are added, how should you deal with the problem of multicollinearity?
