The classic cross-sectional regr디지몬 카드 게임sion (CSR) and mimicking portfolio (MIM) procedur디지몬 카드 게임 디지몬 카드 게임timate factor risk premia on a t디지몬 카드 게임t asset span and the r디지몬 카드 게임ulting t디지몬 카드 게임ts of asset pricing models are performed with reduced degre디지몬 카드 게임 of freedom. Although we can r디지몬 카드 게임trict the risk premia of traded factors to equal expected returns, imposing such r디지몬 카드 게임trictions on nontraded factors is difficult, which may prevent full performance evaluation. We sugg디지몬 카드 게임t t디지몬 카드 게임ting with efficient MIMs that project factors onto a return space spanned by t디지몬 카드 게임t assets and benchmark traded factors. The generalized method of moments (GMM) t디지몬 카드 게임ts show that this approach generat디지몬 카드 게임 more powerful t디지몬 카드 게임ts and fair comparison against a benchmark model.
