Efficient estimation of the equity cost of public corporations is an essential component of computing the required rate of return of real investment projects, and therefore the basis for a rational investment policy. The accepted methodology relies on the CAPM model to define the return risk...

This paper makes specifics contributions in the methodology of event studies. First, it develops a financial econometrics framework for understanding, measuring and testing the impact of outlier returns on the estimated parameters of stock return models. Second, it presents a maximum likelihood...

Stock returns are decomposed into their regular and outlier components using a maximum likelihood outlier resistant estimation method. Analytical results depicting the impact of outliers on the OLS estimated models and CAR statistics are derived and validated using Monte Carlo simulations. The...

We investigate the determinants of the banks' propensity to make long-term business loans in an emerging market context. Using a large sample of Russian banks, we find that the median bank allocates only 0.5% of its assets in long-term business loans and that there is wide cross-sectional...

This paper discusses three families of flexible parametric probability density functions: the skewed generalized t, the exponential generalized beta of the second kind, and the inverse hyperbolic sin distributions. These families allow quite flexible modeling the first four moments of a...

This paper provides a survey of three families of flexible parametric probability density functions (the skewed generalized t, the exponential generalized beta of the second kind, and the inverse hyperbolic sine distributions) which can be used in modeling a wide variety of econometric problems....

We study an equilibrium risk and return model to explore the effects of the coronavirus crisis and associated skewness. We derive the moment and equilibrium equations, specifying skew-ness price of risk as an additive component of the effect of variance on mean expected return. We estimate our...
