This book is written in English and Thai languages. The researcher constructs a base-salary model and a corresponding base-salary scale table for government officers that are adjustable to changing economic conditions. This book adopts an econometric approach in accordance with which stochastic frontier analysis (SFA) was conducted by means of an application of the maximum likelihood estimation (MLE) technique. The base - salary of the military officers is adjustable to prevailing economic conditions. The objective is to be able to calculate the maximum/minimum rate of the salary structure. It also aims to calculate the step-range for each work group.
