RT Journal Article T1 Tax autonomy mitigates soft budget constraint: evidence from Spanish Regions A1 Arespa-Castelló, Marta A1 González-Alegre, Juan K1 política regional AB Within the framework of the soft budget constraint problem, this article investigates theimpact of a legislative reform that increased regional tax autonomy on the propensity ofSpanish regional governments to incur a deficit. For this purpose, a dynamic panel datamodel is estimated, using data for the period 1984–2019. The sample shows a breakpoint in2002, when the reform of the regional financing system came into force, providing Spanishregions with greater tax autonomy, more fiscal competency, and lower intergovernmentaltransfers. Results show that the budget constraint has hardened, as regions have fewerincentives to accumulate budgetary deficits with the expectation of future compensationsfrom the central government. A comprehensive review of the evolution of other factorspreviously identified as determinants of soft budget constraints, and the analysis of tworegions not included in this financing system, suggest no other possible explanation forthese results.
