Tax-Induced Trading: The Effect of the 1986 Tax Reform Act on Stock Market Activity
研究1986年美国税改法案取消长期资本利得优惠税率后，投资者在1986年12月和1987年1月的交易行为变化，发现税改显著影响了交易量，尤其是长期盈利股票的相对交易量大幅上升。
The end of favorable tax treatment for long-term capital gains caused investors to reassess traditional tax-induced trading strategies. This study compares trading behavior in December 1986 and January 1987 with previous years. Our results indicate that these tax code changes had a powerful effect on trading behavior. Relative trading volume was considerably higher in December 1986 for long-term winners but not significantly lower for long-term losers. Results also indicate altered trading patterns based on short-term gains in December 1986 and for long-term winners in January 1987.
