Tax effects in the dutch bond market

In this paper an analysis of the Dutch bond market is made. The technique used is linear programming. Given the fact that coupon income and capital gains are taxed differently and that some investors are tax-exempt in the Netherlands, it is shown that there are overpriced bonds in the market. This is as can be expected. But it is found that there are bonds that a rational investor would never hold in his portpolio, whatever the tax rate the investor has to pay on coupon income. Given the fact that the Dutch bond market is very illiquid for some bonds, an analysis of the effects of bid-ask spreads is made. It is shown that the effect of these spreads cannot explain the existence of bonds that are overpriced. It is not clear where these remaining overpricings stem from.
