Home Bias in Portfolios and Taxation of Asset Income

Abstract

Intuitively, the observed bias in individual portfolios plausibly explains the international capital immobility reported by Feldstein and Horioka (1980) as well as the survival of taxes on capital income. These intuitions are examined in a model where consumers prefer to consume domestically produced goods. The results show that international capital immobility is indeed present in the model: extra domestic savings generate extra investment primarily in the home country. When monetary policy focuses on exchange rate stabilization random domestic prices cause individuals to heavily invest in domestic equity as a hedge against price fluctuations. However our findings show that the specialization of equity portfolios does not necessarily facilitate the taxation of capital income. While random equity returns do facilitate taxes on equity income, as shown in Gordon and Varian (1989) and Huizinga and Nielsen (1997), random consumer prices appear to undermine taxes on capital income.
