Government initiated a new pension program, in which employees are allowed todetermine his/her annual pension contribution ratio. To investigate what factors will affectthe decision on contribution ratio, researcher surveyed 185 employees coming from 10 firmsand set up the following regression model.contrib, = Bo + Bearns, + B,age, + Bmale + B,mrate, + ue(1)Where, i denotes firm; e denotes employee; contrib, denotes firmi employee e'sannual pension contribution ratio; earns denotes the employee's annual income;age denotes the age of employee e;male is a dummy variable, with value of 1 if theemployee is male, 0 otherwise; mrate, denotes the pension contribution ratio made by firmi; u denotes the disturbance term. This model is satisfying the six assumptions for classiclinear regression model. OLS estimation results are reported as follows (standard errors arereported in the parentheses) :contrib,e = 0. 12 + 0.24earnsie + 1.2ageie - 2.46maleie + 0.66mrate;(0.06) (0.06)(0.31)(0.50)(0.12)R2 = 0.40 n = 185
