In a series of papers over the past 10 years, MIT Professor César Hidalgo and his collaborators have argued that the complexity of a country’s exports — not just their diversity but the expertise and technological infrastructure required to produce them — is a better predictor of future economic growth than factors economists have historically focused on, such as capital and education.
Now, a new paper by Hidalgo and his colleagues, appearing in the journal World Development, argues that everything else being equal, the complexity of a country’s exports also correlates with its degree of economic equality: The more complex a country’s products, the greater equality it enjoys relative to similar-sized countries with similar-sized economies.
“When people talk about the role of policy in inequality, there is an implicit assumption that you can always reduce inequality using only redistributive policies,” says Hidalgo, the Asahi Broadcasting Corporation Associate Professor of Media Arts and Sciences at the MIT Media Lab. “What these new results are telling us is that the effectiveness of policy is limited because inequality lives within a range of values that are determined by your underlying industrial structure.
“So if you’re a country like Venezuela, no matter how much money Chavez or Maduro gives out, you’re not going to be able to reduce inequality, because, well, all the money is coming in from one industry, and the 30,000 people involved in that industry of course are going to have an advantage in the economy. While if you’re in a country like Germany or Switzerland, where the economy is very diversified, and there are many people who are generating money in many different industries, firms are going to be under much more pressure to be more inclusive and redistributive.”
