Could you please give me a step-by-step on how to answer these questions from the SCP model, I have chosen industry to base it on so I can obtain necessary information but I need this explained in order to do it since I don't understand it well, for example, How do I get economies of scale? ROE, Economic profit, and total shareholder returns?

The Structure-Conduct-Performance Model traces industry profitability to its root structural causes STRUCTURE-CONDUCT-PERFORMANCE (SCP) MODEL Structure Conduct Performance Financial metrics Economic Profit Competition focused on grabbing share or growing the pie in Pricing Strategy Capacity Investments R&D/M&A Innovation ROE/ROCE% Value Creation Total Shareholder Returns (TSR) Competitive Structure Concentration - Number and size of firms (Herfindal Index) Barriers to Entry and Exit Vertical integration Type of firms (state-owned)? Cost Structure Economies of scale (MES) Fixed vs Variable costs Demand Structure Underlying Growth Power/Size of customers Sales (contract length, purchase frequency, switching costs etc) Growth Implicit collusion
