a All but the highest bracket are indexed since 2022. b Adjusted for average wage growth. c If inflation > 3%. Source: Authors’ compilation based on IBFD and official websites.
Notes: Assumed tax rate of 25 percent. Source: Authors’ calculations.
Assumptions: Tax rate: 25 percent, real return: 3 percent, real discount rate: 0 percent. For the 10-year distributing assets, all distributions (interest, rents, dividends) are assumed to be reinvested at the same conditions. Source: Authors’ calculations.
Source: Authors’ estimates.
Source: OECD’s effective tax rate database, WEO database, authors’ computations.
Notes: The calculations assume a CIT rate of 25 percent, both true economic depreciation and depreciation allowance of 12¼ percent, a real interest rate of 5 percent, and for the EATR, a financial return of 20 percent. Source: Authors’ calculations.
Notes: The graph gives debt shares (for three different inflation levels and a continuum of depreciation rates) for which a marginal increase in inflation leaves the optimal investment volume unaffected (equation 23). Firms with lower debt shares will reduce their investment volume in response to a marginal increase in inflation, while those above will increase it. The simulation assumes ϕ = δ, r = 0.05 and τ = 0.25.

Notes: Table summarizes results of OLS regressions. All specifications include a set of country and a set of year-fixed effects. The variable CIT rate is centred at its mean of 25 percent; the variable Inflation is centred at its median of 4 percent. *, **, and *** indicate statistical significance at the 10, 5, and 1 percent level, respectively. Standard errors in square brackets are heteroscedasticity robust.
