At the Marginal Revolution, based on a paper by Omar Lizardo:
…the data supplied by Professor Lizardo show that the poorer a country, the more likely it will buy and listen to its own domestic music. This makes sense given that music is a form of social networking and the relevant networks are primarily local.
There is an article discussing the same subject on the NYT written by the author of Marginal Revolution.
I skimmed through the paper for regression analysis and I found this on page 15:
Malaysia is somewhere in the middle, above the regression line. You may take a closer look at the graph by clicking on it.
I wonder how the inclusion of population size would affect the analysis.
