Financial autonomy in Spanish local governments: Empirical evidence of beta and sigma convergence
研究了西班牙地方政府的财政自主权指标，通过β收敛和σ收敛方法分析不同规模城市是否呈现共同趋势，发现小城市收敛速度最快，对政策制定者有参考价值。
Territorially, Spanish public administrations are organized into State Administration, Autonomous Community Administration, and Local Administration. Local government has the closest contact with citizens and therefore the powers and decisions taken by local institutions have the greatest impact on the social welfare of citizens. To ensure this well-being, it is necessary to analyze and pay attention to the administrative and financial autonomy of local governments. Financial autonomy translates into the capacity of local entities to govern their respective finances, determining, within certain limits, the level of the volume of their own resources and organizing their expenditures. In this work, we study the Financial Autonomy Indicator, which aims to determine the tax resources available to the local entity. Taking into account that Spanish municipalities have, depending on their population size, different obligations when providing services to citizens, the convergence of financial autonomy is studied to detect whether there are common trends by applying the techniques of β-convergence and σ-convergence. It is analyzed whether municipalities starting from lower indicators achieve higher growth over time ( β-convergence), and whether dispersion between municipalities is reduced ( σ-convergence). Points for practitioners Local autonomy grants local entities the freedom to manage their own interests within the State's legal framework. Greater economic diversity and the ability to raise more money on their own through taxes, fees, and other sources characterize larger communities. They have a wider tax base thanks to their higher economic diversification, which opens up more opportunities for revenue collection. The speed of convergence is highest in the smallest municipalities. Knowing whether there is convergence or divergence in financial autonomy can help policy makers.
