Hence there has actually been lot research and discussions come design and also determine the shape of the sales an answer curve or in other words the diagrammatic representation of the relationship of advertising expenditure and sales have been under lot debate.

Out of the full discussions 2 models have been conceptualized under proclaiming Sales an answer Models viz. The concave-downward function or the S-shaped solution curve.

1. The concave-downward function:

Julian Simon and Johan Arndt reviewed more than 100 research studies of the impacts of advertising on sales and concluded that the effects of heralding budgets follow the microeconomic law of diminishing returns. In other words increase in advertisement expenditure lead to decrease in the value.

Repetition of the advertisements and increase in advertisement expenditure do not wake up purchase amongst those civilization who execute not want to buy. With every repeat of the advertising there is no additional information provided to the currently potential buyers, which might persuade castle to go ahead and make the purchase. According to the concave-downward function model, the results of advertising start to diminish and hence low advertising expenditure may be needed to produce the optimal influence on sales.

The second set that opinions is depicted in the S-shaped response curve, which jobs an S-shaped response function to the budget outlay.

After a details amount of expenditure has been made i.e. The certain is in range B, advertising and promotional efforts begin to have actually an effect, as additional increments the expenditures result in raised sales. But this rise in sales continues only to a point and after the in selection С extr expenditures outcomes in practically no or very little sales.
