This chapter surveys recent econometric methodologies for inference in large dimensional conditional factor models in finance. Changes in the business cycle and asset characteristics induce time variation in factor loadings and risk premia to be accounted for. The growing trend in the use of...

We compare valuation effects associated with debt issuance under SEC Rule 144A versus issuance in the public market. We find that nonconvertible debt Rule 144A issuers experience an incremental positive announcement effect when compared to their counterparts issuing in the public market. We...
