Outline of Final Research Achievements

Econometricians often encounter problems in which the dependent variables (e.g., consumption and savings) are fully observed but the independent variables (e.g., assets and expected income) are partially observed. Most studies of such cases assume that the missing independent variables are missing at random (MAR). Using the partial identification approach, I identified sharp bounds on the parameters of the independent variables, some values of which are missing, without assuming MAR.
