Henry George not only analyzed how the land tenure and taxation systems of his day, which have continued into our time, help cause social problems such as poverty and depressions, but also how such economic problems can be remedied. Basically, the Georgist or geo-economic remedy is a shift of taxation, untaxing incomes, sales, and buildings, and shifting taxation to land rent. An evident result of such a tax shift would be to increase the productivity of the economy.
Efficiency is increase first by the removal of the taxes on productive activity.
As we know from basic economics, goods in current production typically have an upward sloping supply curve. At higher prices, there is a greater quantity supplied. A tax shifts the supply curve up by the amount of the tax, since the supplier has the same costs of production. The price then moves up the demand curve, and the quantity of the good is correspondingly reduced. The tax itself is not a social loss, since it just transfers funds from one group to another.
