At the unregulated competitive equilibrium, marginal social cost is greater than marginal social benefit. You can view marginal benefit as the satisfaction that a consumer might receive from purchasing an additional product. In the move from Q1to Q2, private agents reduce their costs by f (they are producing less so costs should be less; f is the area underneath the marginal private cost curve between Q2andQ1) but also decrease their benefit by e+f (the area under the marginal private benefit curve between the two quantities of interest). Instead they could wait until the price goes down. We're going to talk about this idea right over here that some of these consumers are getting more for their money than what they have to pay, or at least in their own minds they are. @reasonStore I mean just another trivial example of utility function U=x at such utility marginal utility is given by 1.
