“…We regress these companies' costs of debt on an ordered categorical variable indicating whether their local Indonesian audit firm was affiliated with (1) a Big4 audit firm, (2) a second‐tier audit firm, or (3) none of the two, together with various control variables, including interest coverage, profitability, leverage, asset tangibility, size, the occurrence of negative equity, age, growth, and cash flow performance. In line with prior studies (J. Francis, LaFond, Olsson, & Schipper, ; Minnis, ; Vander Bauwhede, De Meyere, & Van Cauwenberge, ), we proxy the cost of debt by the effective interest cost; that is, the ratio of the interest expense to the average amount of financial debt.…”
