The stationarity of consumption-income ratios: evidence from South American countries

This paper analyzes the order of integration of the consumption-income ratio in 10 South American countries. To do this, the individual ADF test, its panel versions and theMinimumLMunit root test with structural break(s) were employed. While the former tests found more favorable evidence of an integ...
