Here are two common myths about big business and why they are wrong.

The failure of the Solow model to duplicate the growth data quantitatively leads us to look for differences across countries in productivity. Why do some countries get less output from the same level of inputs as do other countries? The first half of...

The Solow model is consistent with some aspects of the data on growth but not with other aspects. What do we learn from the consistencies and the inconsistencies?

The Solow Model is a workhorse model of economic growth. Many subsequent papers in growth theory (and in business cycle theory) build on this model. A model of growth helps us to structure our thinking. Why is it, for example, that China is growing...

How do we compare the standard of living in two different countries or in the same country over time? Comparisons of per capita Gross Domestic Product are one possible answer but what is GDP? What is nominal GDP? What is real GDP? And how do we compare...

The rule of 70 is a useful rule of thumb for quickly calculating the doubling time for something (e.g. population, GDP, internet nodes) that is growing at a constant rate; it says the doubling time is 70/growth rate. See the video for details and some...

Do rapid rates of growth propel developing nations to fully developed status, or do some countries tend to get "stuck"?  The latter seems to be true, so here's a look at what we know about a puzzling and important phenomenon.

This is a quick look at one of the basic models of economic growth, explained with words only.  It's an introduction to the more mathematical videos on the Solow model, but if you don't get the math it is also fine to stop here.
