Due to the fact that mediation model involves several linear regression equations, there is concern not only when the data contain observations that are extreme in the response variable but also in the regressor space, namely the leverage points. The Diagnostic Robust Generalized Potentials (DRGP) procedure in multiple linear regression incorporated the Robust Mahanalobis Distance based on the ...

In modern portfolio theory, the balancing of expected returns on investments against uncertainties in those returns is aided by the use of utility functions. The Kelly criterion offers another approach, rooted in information theory, that always implies logarithmic utility. The two approaches seem incompatible, too loosely or too tightly constraining investors’ risk preferences, from their respe...

Current theories of capital structure have difficulty explaining the aspects of financing behavior we document. In contrast to the tradeoff theory, seasoned equity offers frequently move firms away from their target leverage ratios. At odds with the pecking-order theory, SEO firms typically are financially healthy companies with low leverage, unused debt capacity and substantial cash balances. ...

We analyze equilibrium leverage dynamics in a dynamic tradeoff model when the firm is unable to commit to a leverage policy ex ante. We develop a methodology to characterize equilibrium equity and debt prices in a general jump-diffusion framework, and apply our approach to the standard Leland (1998) setting. Absent commitment, the leverage ratchet effect (Admati et al. 2015) causes firms to tak...

This paper incorporates the cost of adjustment between observed and optimal leverage in explaining the variation in firm’s equity or bank-debt financing investments. Using a dynamic adjustment approach identifies the determinants to capital structure between different financial systems. In relation to firm sales U.K and U.S firms have 50-100 percent more equity financing than Swedish firms depe...
