- Argentina is a federal republic made up of 23 provinces and an autonomous city (Buenos Aires). It has a population of over 43 million people. - Sub-national governments rely on direct taxes like sales tax and property tax as well as federal transfers for revenue. More developed provinces receive a larger share of transfers. - Provinces have jurisdiction over areas like education and police, while the federal government oversees customs, defense, and foreign relations. - Provincial debt levels rose significantly after the peso was devalued in 2001. Mechanisms to collateralize debt include intercepting federal revenue shares and using natural resources royalties. Experience with provincial bonds has been mixed.
