In a market for a woodworking the inverse demand market function is given by p=100-Q and the marginal private cost of production for the aggregation of all firms is given by MC=10+Q. The environmental pollution due to deforestation creates external damage given by the external cost curve MEC=Q. Calculates the output and price of wood working if it is produced under competitive condition without regulation. Determine the socially efficient price and output of woodworking.
