Gecko Insurance is planning to offer a new type of combined auto and renter's insurance product. Their chief statistician, Albert Gorithm, estimated the parameters of Bass's diffusion model for two potential markets. The results follow:

Market 1: S_t= 2650 + 0.57Y_t-1 - .00022y²_t-1

Market 2: S_t= 14380-0.36Y_t-1 - .00065²_t-1

Remember that the general equation for sales in any time period t is:

S_t= p₀m+(q-p₀)Y_t-1- (q/m)Y²_t-1

Where S (t)= sales ('000s) in period t; p = coefficient of innovation; q = coefficient of imitation; m= sales potential or saturation level; Y_t-1=total people who have ever bought (cumulative sales) by end of period t-1

Draw the shape of the predicted sales curve for each market and explain your answer in each case. Show the starting sales level (period 1) and draw the shape carefully.
