Cost of equity estimation techniques used by valuation experts
Kolouchová, Petra; Novák, Jiří - 2010
most popular model for cost of equity estimation is CAPM, which is followed by the heuristic build up model. In the case of … CAPM, risk premiums for unsystematic risks are often applied. Such premiums depend to large extent on expert's own …

Conditionally parametric fits for CAPM betas
Abberger, Klaus - 2004
The CAPM model assumes stock returns to be a linear function of the market return. However, there is considerable …

One-factor-Garch models for German stocks: Estimation and forecasting
Kaiser, Thomas - 1996
This paper presents theoretical models and their empirical results for the return and variance dynamics of German stocks. A factor structure is used in order to allow for a parsimonious modeling of the first two moments of returns. Dynamic factor models with GARCH dynamics (GARCH(1,1)-M,...

Nonparametric identification and estimation with non-classical errors-in-variables
Evdokimov, Kirill S.; Zeleneev, Andrei - 2024
This paper considers nonparametric identification and estimation of the regression function when a covariate is mismeasured. The measurement error need not be classical. Employing the small measurement error approximation, we establish nonparametric identification under weak and...

Inference for rank-rank regressions
Chetverikov, Denis N.; Wilhelm, Daniel - 2023
Slope coefficients in rank-rank regressions are popular measures of intergenerational mobility, for instance in regressions of a child's income rank on their parent's income rank. In this paper, we first point out that commonly used variance estimators such as the homoskedastic or robust...

Design-based identification with formula instruments: A review
Borusyak, Kirill; Hull, Peter; Jaravel, Xavier - 2023
Many studies in economics use instruments or treatments which combine a set of exogenous shocks with other predetermined variables by a known formula. Examples include shift-share instruments and measures of social or spatial spillovers. We review recent econometric tools for this setting, which...

Identification based on higher moments
Lewis, Daniel J. - 2024
Identification based on higher moments has drawn increasing theoretical attention and been widely adopted in empirical practice in macroeconometrics in the last two decades. This article reviews two parallel strands of the literature: identification strategies based on heteroskedasticity and...

Robust estimation and inference in panels with interactive fixed effects
Armstrong, Timothy B.; Weidner, Martin; Zeleneev, Andrei - 2023
We consider estimation and inference for a regression coefficient in panels with interactive fixed effects (i.e., with a factor structure). We show that previously developed estimators and confidence intervals (CIs) might be heavily biased and size-distorted when some of the factors are weak. We...

The stable long-run CAPM and the cross-section of expected returns
Kim, Jeong-Ryeol - 2002
The capital-asset-pricing model (CAPM) is one of the most popular methods of financial market analysis. But, evidence … of the poor empirical performance of the CAPM has accumulated in the literature. For example, based on their empirical … results regarding the relation between market Beta and average return, Fama and French (1996) conclude that the CAPM is no …
