Let C ( x , φ ) denote a firm’s cost of abating pollution to level x , where c ( x , φ ) = 0, c ( 0, φ ) > 0, and c x < 0. φ is a variable that affect the firm’s costs. This parameter is known to the firm, but is uncertain for the planner. Let D ( x ) denote the social damage caused by pollution level x . Finally, let P ( x ; s , l , p ) = sx + p max [ x- l ,0 ] be the penalty function that the planner uses to regulate pollution. Thus, the planner’s problem is min x E [ D ( x ) + C ( x , φ )] and the firm’s problem is min x P ( x ) + C ( x , φ ) ....
