Consider the following model of revenue: REVit = so x Kg; x L'5 xA1_\"_p I tl itl Where REV\" is the revenue (in millions of dollars) of iirm i in period t, Kt_ _1 is the capita expenditure of the rm 1n period t 1, Lit_ is the labour input of the rm 1n period t1 and AM is the advertising expenditure oi the rm in period t 1. We know that the most popular empirical model in Finance is Ordinary Least Square (0L8) which is also known as the Best Linear Unbiased Estimator (BLUE). Suggest how can yo estimate the revenue model using 0L8? How would you interpret the a and [3 coefcients from the OLS model? You ohserve the following data regarding the key parameters and inputs of the model based on historical data:
