Up to the 1930's, Argentina and Canada were very similar countries: rich, sparsely populated, income mostly from natural resources and agriculture, lots of immigrants, similar GDP per capita. Then after World War II, the economic fortunes of those two countries drifted apart. What happened?
Germán González and Valentina Viego think that Canada benefited from a rich and large neighbor that was a nice complement to Canada. Argentina, however, did not have this advantage and fell into a trap that made it more and more reliant on its core products and prevented it for following a "normal" development path towards industrialization. This conclusion comes from a fairly standard growth accounting exercise that highlights how Argentinian economic efficiency did not keep up with Canada's starting in the 1930's, primarily due to higher technology adoption in Canada. The latter is clearly helped by the vicinity of the US, while Argentina compounded things by adopting an ill-advised import substitution policy.
