De/centralization in Argentina, 1862–2020.

Argentina exhibits an overall trend toward centralization, although not linear across time or policy areas, accompanied by strong centralization in the fiscal sphere, and greater politico-institutional autonomy for the provinces. These findings arise from a unique dataset gathered by 22 research assistants and curated by 18 experts for 22 policy areas, 5 fiscal dimensions, and 3 politico-institutional autonomy areas. In 1862, the country was very decentralized, but state building soon consolidated the federal government's role in policymaking and fiscal relations, while provinces struggled to keep their politico-institutional autonomy until the 1960s, when challenges to their autonomy started to decrease. A centralization peak is observed in 1949, while decentralization junctures took place after the military coups of 1955 and 1976, and during the 1990s. Regime change cannot explain these changes. Instead, policy and fiscal de/centralization is best explained by the state-building process, the strength of presidents, and the economic trends. [ABSTRACT FROM AUTHOR]
