This paper examines the effects of liquidity on the stock and portfolio risk measure by Value at Risk (VaR). Using daily stock returns and firm market capitalization, empirical calculation of VaR that confirmed not yet succeeded to prove pattern of relations between risk and liquidity both...

Especially with the evaluation of non-listed (medium-sized) companies, the following problems and significant restrictions pertaining to the applicability of the CAPM must be taken into account when determining cost of capital. 1. Homogeneity of expectations and planning consistency. Given the...

This paper examines the effects of liquidity on stock and portfolio risk measures by analyzing Value at Risk (VaR). Using daily stock returns and firm market capitalization, empirical calculations confirmed that VaR has not yet succeeded to prove patterns of relation between risk and liquidity,...

While most accounting information is idiosyncratic in nature, economy-wide factors such as accounting standards affect the quality of idiosyncratic accounting information of many firms simultaneously. We study idiosyncratic and systematic features of accounting information by embedding a...
