Abstract

In this study, first and second degree approximations of bivariate Lagrange INTERPOLATION is applied to make employment time series in construction sector for period of time 1345-1379 that there is missing data. Wage and value added in constant price 1376 is used for INTERPOLATION. INTERPOLATION function is made from two first degree polynomials. These polynomials use from two and three NODs, respectively. In addition, a two degree polynomial is introduced that uses from 3 NODs. The best estimation obtained from a combination of polynomials, that is, INTERPOLATION function is a multivalued function that for each given period of time uses one of polynomials. Then EMPLOYMENT FUNCTION is estimated that indicates R-square adjusted is 97.1 percent and all signs of coefficients estimated are reasonable.
