Current asset pricing models require mean-variance efficient benchmarks, which are generally unavailable because of partial securitization and free float restrictions. We provide a pricing model that uses inefficient benchmarks, a two-beta model, one induced by the benchmark and one adjusting...

This study examines, for the first time consistently, the performance of contrarian (value) strategies in the Athens Stock Exchange (ASE) based on the price/earnings ratios, dividend yields, size (in terms of market value), market to book ratios, financial leverage ratios and the beta...

This article reviews the recent scientific contributions which led to the emergence of the new multidisciplinary domain research of neurofinance, as a subsector of behavioral finance. Neurofinance as a cross-disciplinary field integrating Neurophysiology, Psychology and Finance adds to the...

We show the equivalence between the zero-beta version of a multi-factor arbitrage pricing model and a linear pricing model utilizing undiversified inefficient benchmarks in a given factor structure. The resulting linear model is a two-beta model, with one beta related to the inefficient...
