A government agency caps aggregate emissions of an air pollutant within its borders, establishes initial pollution allowances across all firms, and grants the firms the right to trade these allowances among themselves. The demand and supply curves for these pollution allowances have normal shapes and intersect at a positive price. Explain in your own words the government's likely goal in establishing this private market for pollution allowances.

Thus authorities tends to encourage firms can barter the permissions to themselves in any occasion as their produce greater contaminants than even the ceiling allowed so at penalty of buying paid these. This government expects the lessen the quantity the chemicals discharged into rivers inside this fashion. With strengthening that sector, it company expects it achieve target degree of carbon as reduce impurities.

This provision on exemptions derives by enterprises that already have empty permissions owing to low emissions. Such profit comes from companies producing extra waste.

This value during which the supply sought licenses balances the supplied wants to clear any industry with permission. This is now the cost over which the economy deletes. This higher pricing below shows its costs for the business in producing each individual component environmental pollute. The cost is $P$where its market forces curves cross there in example figure.
