Revisiting the nexus betwixt fiscal decentralization and regime size - The office of ethnic fragmentation

Abstract

The extant literature on the human relationship betwixt fiscal decentralization and authorities size provides mixed evidence. In this paper, we apply a console of 65 developed and developing countries from 1972 to 2013 to analyse the role of ethnic fragmentation as a mediator in this human relationship. Using FGLS for heterogeneous panels, arrangement GMM and instrumental variable methods, we discover that financial decentralization is inversely associated with government size, but the relationship is positive and significant when variation in ethnic fragmentation is considered. Our findings support the theory that the heterogeneous needs and preferences of an ethnically fragmented region lead to an increment in the demand for public appurtenances and services provision, thereby increasing the level of aggregate government spending through financial decentralization. The results are robust across alternate definitions of fiscal decentralization, model specification, and estimation methods.

Introduction

Understanding fiscal decentralization is key in the study of fiscal policy and decentralization reforms, and then the topic has earned a great deal of attention in public finance (Oates, 2005; Weingast, 2014). Studies on financial decentralization look both at its determinants (Oates, 1972; Panizza, 1999; Letelier, 2005; Bodman and Hodge, 2010; Canavire-Bacarreza et al., 2016) and its impacts on other economic factors, including government size, government spending composition, economical growth, regional disparity, governance quality, and corruption (Martinez–Vazquez et al., 2017).1 Increasing rates of fiscal decentralization policy across the globe imply a more urgent demand to sympathize it (Garman et al., 2001; Hooghe et al., 2010).

In this paper, nosotros re-visit the impact of financial decentralization on government size where no consensus has been reached in the extant literature, either in theoretical or empirical terms (Golem, 2010; Martinez–Vazquez et al., 2017) and examine the office of indigenous fragmentation backside such mixed findings. The 2 contradicting views of the impact of fiscal decentralization on government size are attributed to two different generations of theories of fiscal federalism. The older theory holds that financial decentralization is associated with an overall increase in government spending. The theoretical justification is that since fiscal decentralization brings the public jurisdiction closer to the needs and preferences of the local people, it augments the efficiency and quality of governance in public service delivery. This happens especially in the existence of heterogeneity in demand and preferences of public goods and services across jurisdictions (Tiebout, 1956; Oates, 1972).

Newer theory suggests that fiscal decentralization restricts overall public spending. The main idea behind this hypothesis is that, under decentralization, the mobility of firms and citizens across jurisdictions gives rising to a competitive pressure level to reduce the "tax price". This ultimately results in bringing downwardly the Leviathan monopoly of the government, which otherwise aims to maximize its size of revenues through higher levels of taxation. This brings the local preferences of people closer to the jurisdiction, thereby resulting in less bureaucratic waste material of public resources and reducing the overall size of government spending (Oates, 1985; Weingast, 2009).

Both theories focus on local needs and preferences for public goods provision as an explanation for the effects of fiscal decentralization. In this study we use the mediating cistron of ethnic fragmentation to bridge these opposing effects. Indigenous fragmentation refers to individuals within a country belonging to many different cultural, linguistic, and/or religious groups (Alesina et al., 1999). Higher ethnic diversity implies heterogeneous preferences, which we might wait would atomic number 82 to bigger increases in government spending when decentralization occurs than in a more homogenous area (Panizza, 1999; Tanzi, 2000; Dreher et al., 2018).

We test this hypothesis on a console ready of 65 developed and developing countries spanning over the fourth dimension period of 1972–2013. We find that the impact of financial decentralization on regime size is negative in general, just with ethnic fragmentation as a mediating factor, this relation is positive. These key results are robust to the apply of alternative indicators, different subsamples, the employ of urbanization as an musical instrument, and other robustness tests.

The paper is structured equally follows: Section 2 reviews the literature, the empirical specification and data are in Section iii, the results are in Section 4, the robustness checks are in Section v, limitations of this written report are outlined in Department 6, and finally, Department 7 concludes.

Financial decentralization and government size

Two major strains of literature on the relationship between fiscal decentralization and government size support the theory that the effect should be positive, and that information technology should exist negative. These sides can be regarded equally focusing on demand side and supply side explanations respectively (Qiao et al., 2019). The need side caption can be attributed to the traditional theories of financial federalism, known as the first generation theory of fiscal federalism, with seminal works by Musgrave

Estimation procedure

In gild to examine the touch on of fiscal decentralization upon regime size with the mediating effect of indigenous diversity, nosotros estimate the model in Equation (one): Grand it  =α +βFD information technology  +πEFI information technology  +γ(FD it *EFI it ) +θX it  +Ω i  + t  +μ it where Yard information technology refers to aggregate government size measured in terms of general government expenditure as a percentage of GDP in country i and time period t. EFI it is the ethnic fragmentation alphabetize, and FD information technology *EFI it , the variable of interest, is the interaction between financial

Main results

Table 3 shows results from the baseline FGLS regression model with heteroscedastic panels, with and without the consideration of time effects under each of its respective specifications. Results show that fiscal decentralization is associated with a decrease in government size. Taking column ane every bit a reference, the coefficient on fiscal decentralization is negative and statistically significant. This supports the 2d generation theory of fiscal federalism. This result is robust to the

Robustness checks

In this section we check if the primary results of the baseline model in Table 3 are robust across alternative measures of fiscal decentralization, alternative econometric models, and alternative sample. Additionally, potential endogeneity issue in the model has been addressed by two-stride arrangement GMM interpretation and use of instruments.

Limitations of this study and scope for future work

We acknowledge that the present written report considers only aggregate measures of government size or expenditure and not the expenditure components.ix As pointed out past Gisselquist (2014), the outcome of regime size and financial decentralization might depend on the different types of authorities expenditure considered. However, due to sporadic and uneven data availability, this practice could non exist considered at present and remains a possible future

Conclusion

Despite improvements in sample size, measurement, and methodology in the literature on the relationship between fiscal decentralization and regime size, there has been no consensus on the sign of the effect. Both theoretical and empirical papers take opposing findings. To address this theoretical and empirical ambivalence, we include ethnic fragmentation, a determinant of need for public goods provision, as a mediator of the effect. By focusing on the demand side office of ethnic diversity,
