"Land" in economics has in the history of thought been defined as natural resources. Improvements such as landfill and the production of islands are capital goods, not natural resources. Space never gets altered and is always land, but soil and rocks after being altered by human action become capital goods. > Is that an > increase in the supply of "land" or an increase in > its productive capacity? Greater occupancy produces capital goods and makes more use of existing space.

Taxing buildings imposes an extra cost on producing capital goods.

But even in the short run, a tax shift raising the tax on land and reducing the tax on buildings can be made revenue neutral, thus with no loss of tax revenue. Fred Foldvary
