LINEAR INVERSE PROBLEMS IN STRUCTURAL ECONOMETRICS ESTIMATION BASED ON SPECTRAL DECOMPOSITION AND REGULARIZATION.

Chapter 8 of the book "Handbook of Econometrics," edited by James J. Heckman and Edward E. Leamer is presented. It presents an introduction to the estimation of the solution to inverse problems where the value of the function is known but the argument is undetermined. The integral equations of the first kind is also given emphasis. In addition, a review of the different regularization methods and a study about the properties of estimator are also tackled.
