“…The studies in Table 1 also use various econometric approaches to account for potential endogeneity of fiscal rule adoption ranging from a Difference-in-Difference (DiD) estimation (e.g., Carrieri & Martínez, 2021, Daniele et al, 2019), a combination of DiD with a Regression Discontinuity Design (RDD) which is labelled as Difference-in-Discontinuities (e.g. Grembi et al, 2016or Alpino et al, 2022, entropy balancing as a form of matching on covariates determining fiscal rule adoption on the country level (Vinturis, 2022), synthetic control methods (Salvi et al, 2020), or they use cross country fixed effects panel regressions to examine relationships between fiscal rules and public investments on the macro-level (Grosse-Steffen et al, 2021, Ardanaz et al, 2021, de Biase & Dougherty, 2022, Delgado-Téllez et al, 2022. Furthermore, available studies use heterogeneous accounting measures of public investments (partly due to the different empirical settings of the studies considered, e.g., local or national levels of observation).…”
