Inflation in Brusov–Filatova–Orekhova Theory and in Its Perpetuity Limit: Modigliani–Miller Theory
摘要
In this Chapter the influence of inflation on capital cost and capitalization of the company within modern theory of capital cost and capital structure—Brusov–Filatova–Orekhova theory (BFO theory) (Brusov et al., Appl Financ Econ 21(11):815–824, 2011, Res J Econ Bus ICT 2:16–21, 2011, Res J Econ Bus ICT (UK) 2:11–15, 2011, Financ Credit 435:2–8, 2011, Res J Econ Bus ICT 2:16–21, 2011, Appl Financ Econ 22(13):1043–1052, 2012, J Rev Glob Econ 1:106–111, 2012, J Rev Glob Econ 2:94–116, 2013, J Rev Glob Econ 2:94–116, 2013, J Rev Glob Econ 2:183–193 2013, Cogent Econ Financ 2:1–13, 2014, J Rev Glob Econ 3:175–185, 2014; Filatova et al., Bull FU 48:68–77, 2008) and within its perpetuity limit—Modigliani–Miller theory (Мodigliani and Мiller, Am Econ Rev 48:261–297, 1958, Am Econ Rev 53:147–175, 1963, Am Econ Rev 56:333–391, 1966) is investigated. By direct incorporation of inflation into both theories, it is shown for the first time, that inflation not only increases the equity cost and the weighted average cost of capital, but as well it changes their dependence on leverage. In particular, it increases growing rate of equity cost with leverage. Capitalization of the company is decreased under accounting of inflation.
