But if LVTs are so great, why are they so rare? One explanation is that it is too difficult to value land separately from what sits on it. There is not much of a market, for example, for undeveloped land in central London. However, some think this can be overcome. The 2010 Mirrlees Review of British taxation argued that bean-counters could compare the price of similar buildings in different locations, for instance. In any case, the efficiency of the tax does not depend on accurate valuations. The bigger barrier is political. LVTs would impose concentrated costs on today’s landowners, who face a new tax bill and a reduced sale price. The benefit, by contrast, is spread equally over today’s population and future generations. This problem is unlikely to be overcome. Economists will continue to advocate LVTs, and politicians will continue to ignore them.
