In the context of conditional least-squares estimators, we have added Theorem 2.3, a sufficient condition for one of our assumptions, and Corollary 2.4 for a special case with a lighter condition on moments. This paper considers the estimation problem in dynamic games with finite actions. The relationship between ALS and maximum likelihood is discussed.

Founded in 1933 by a group of young British and American economists, The Review of Economic Studies aims to encourage research in theoretical and applied economics, especially by young economists. the method of least squares is a standard approach in regression analysis to approximate the solution of overdetermined systems (sets of equations in which there are more equations than unknowns) by minimizing the sum of the squares of the residuals (a residual being the difference between an observed value and the fitted value provided by a Tobit regression, Asymptotic Least Squares, Remittances, International migration. The usual method of estimation in this case is the least squares method, and the least squares estimator (LSE) is given by n = ( X n t X n) - 1 X n t Y, where the design matrix Xn is supposed to have full rank.
