Monopolistic competition Monopolistic competition is a form of imperfect competition where many competing producers sell products that are differentiated from one another (that is‚ the products are substitutes‚ but‚ with differences such as branding‚ are not exactly alike). In monopolistic competition firms can behave like monopolies in the short-run‚ including using market power to generate profit. In the long-run‚ other firms enter the market and the benefits of differentiation decrease with

DEMAND FORECASTING Demand forecasting is the process of predicting future average sales on the basis of historical data samples and market intelligence. The volatility of demand from an average level is supplied from the safety inventory. Any forecast is likely to be wrong‚ so the focus should be on understanding the range of potential forecast errors and the level of safety inventory that will cater for peak demand. An important additional calculation is forecast bias. This is the cumulative
