(1) Compiling an accurate and dependable set of indicators that show the role each economic sector plays in Nebraska's economy and each sector's legal tax incidence by tax types. The purpose is to develop an appropriate share for each economic sector's responsibility for state and local taxes;

(2) The amount of taxes, fees, and other governmental costs imposed on each economic sector which amount shall include those taxes, fees, and other governmental costs imposed on individuals employed in industries in such sector; and

(3) If possible, an estimate of those state and local taxes, fees, and other governmental costs which are exported outside the state or offset by provisions of state and federal tax laws.
