British Tax Policy 1979–90: equity and efficiency
研究了1980年代英国保守党政府的税制改革，评估其对效率和公平的影响，发现税收变得更累退，但效率提升不大。
The Conservative government in Britain in the 1980s was regarded as a tax reforming administration. ‘Tax reform’ is short-hand for efficiency in taxation which requires low rates on a wide base. There is a view that economic performance was improved, though at the expense of equity. This paper gives an account of the changes which took place and assesses their effects on both efficiency and equity. It finds that taxes became more regressive butt hat it is unlikely that there were any large efficiency gains. This is because though the rates of some taxes (especially income tax) were reduced, others were raised and, apart from corporation tax, tax bases remained the same or were narrowed. In particular the income tax base was made narrower by the introduction of new reliefs and the growth of old ones. Such changes are bad for both equity and efficiency.
