Generalizing Cooper-Kaplanis (1994), we estimate implied costs that reconcile international portfolios with InCAPM predictions. Costs depend on home- and host-country characteristics and on interactions; we estimate risk tolerance rather than pre-specifying it; and we control for currency risk,...

Using an international Thomson Reuters Datastream database, where size coverage is unusually wide and data errors have been reduced to a low level, we show that some specification decisions, and especially those related to size, may have a significant impact on asset-pricing test results. We...

The martingale hypothesis for futures prices is investigated using a nonparametric approach where it is assumed that the expected futures returns depend (nonparametrically) on a linear combination of predictors. We first collapse the predictors into a single‐index variable where the weights...

Regressions often use pre-orthogonalized regressors: prior to the main regression, an independent variable xi is regressed upon the other regressor(s), and its residuals are used in the right-hand side of the main regression instead of the raw variable itself. For example, the exposure of a...
