In all three cases, when the rental contract expires in the long run, assuming revenues do not improve, the firm should exit this business. At the long run cost minimizing level of output LRTC = STC; LRATC = SATC and LRMC = SMC, the short-run cost curves being contingent on K being at its long-run optimal level. In the long run, purely competitive firms will be both productive and allocatively efficient. Microeconomics is all about how individual actors make decisions. Microeconomics looks at the individual markets that make up the market system and is concerned with the choices made by small economic units such as individual consumers, individual firms, or individual government agencies. https://www.thoughtco.com/the-short-run-vs-long-run-1146343 The long-run equilibrium is shown in the figure at point V, where the firm’s perceived demand curve touches the average cost curve.
