dViswanath (1992) for a detailed discussion of this point. Appendix Proposition 1 If a positive probability of default exists, the insurer mayoptimally refrain from investing in tax-exempt bonds, even when thetax-exempt yield is greater than the after-tax yield from taxable bonds.However, the insurer may optimally refrain from investing in taxablebonds when the taxable yield is sufficiently close to (but larger than)the tax-exempt yield. Proof We first show that [Delta] [[Pi].sub.p]/[Delta] [Theta] evaluatedat [Theta] = 0 can be positive, even when [e.sup.[r.sub.e]] [is greaterthan] [e.sub.r]-[Tau]([e.sup.r]-1). From equation (7) we have (A1) [[Pi].sub.p] = [A.sub.0] - [[A.sub.1][e.sup.-r]N([-d.sup.2])- PV ([L.sub.1])N([-d.sub.1])+[Tau][{[[Pi].sub.p]+[A.sub.0] (1-[Theta])([e.sup.r]-1)} [e.sub.-r]N([-w.sub.2]) - PV([L.sub.1]) N([-w.sub.1])].Differentiating equation (A1) throughout by [Theta] and noting thatthe term [[A.sub.1] [e.sup.-r]N([-d.sub.2]) - PV([L.sub.1])([-d.sub.1])]is the present value of Max([A.sub.1] - [L.sub.1],0) and hence does notdepend on [Theta], (A2) [Delta] [[Pi].sub.p] / [Delta] [Theta] = [Delta] [A.sub.0]/[Delta] [Theta] + [Tau] [e.sup.-r]N([-w.sub.2])[[Delta] [[Pi].sub.p]/[Delta] [Theta] + (1-[Theta])([e.sup.r] - 1) [Delta] [A.sub.0] Bleu Jaune Nike air max 90 Homme / [Delta][Theta] - ([e.sup.r] - 1)[A.sub.0]].Noting that [A.sub.0] = [A.sub.1] [e.sup.[Alpha]] and using thedefinition of [Alpha], (A3) [Delta] [A.sub.0]/ [Delta] [Theta] = [A.sub.1][e.sup.-2[Alpha]] ([e.sup.r]-[e.sup.[r.sub.e]] Nike air max 90 Homme Blanc Noir .Using equation (A3) in (A2) and rearranging terms, (A4) [Delta] [[Pi].sub.p]/ [Delta] [Theta] = [[A.sub.1][e.sup.-2[Alpha] ([e.sup.r]-[e.sup.[r.sub.e]] + [Tau][e.sup.-r]N([-w.sub.2] [A.sub.1][[e.sup.-2[Alpha]](1-[Theta])([e.sup.r]-[e.sup.[r.sub.e]])-([e.sup.r]-1)[e.sup.-[Alpha]]]]/ 1-[Tau] [e.sup.-r]N([-w.sub.2]).The right-hand side of equation (A4) will be nonnegative adj.Of, relating to, or being a quantity that is either positive or zero.Adj. 1. nonnegative - either positive or zero at [Theta] =0 if (A5) ([e.sup.r] - [e.sup.[r.sub.e]]) [is greater than or equal to][Tau]N(-w.sub.2])([e.sup.r]-1)/ 1 + [Tau][e.sup.-r]N(-w.sub.2)([e.sup.r]-1).When [e.sup.[r.sub.e]] = [e.sup.r]-[Tau]([e.sup.r]-1), equation (A5)is satisfied as a strict inequality. It follows by the continuity of allthe functions in equation (AS) that it can hold as a strict inequalityeven for some values of [r.sub.e] such that [e.sup.re] Gris Blanc Bleu Nike air max 90 Homme [is greater than][e.sup.r]-[Tau]([e.sup.r]-1). Next we show that [Delta] [[Pi].sub.p]/ [Delta] [Theta] evaluatedat [Theta] = 1 can be negative even when r [is greater than] [r.sub.e].From equation (A4), [Delta] [[Pi].sub.p]/ [Delta] Nike air max 90 Gris Bleu Blanc Homme [Theta] [is less thanor equal to] 0 at [Theta] if (A6) (r - [r.sub.e]) [is less than or equal to] ln[[Tau][e.sup.-r]N ([-w.sub.2] Femme Nike air max 90 Gris Rose Bleu )([e.sup.r]-1) + 1].The above inequality is a strict inequality for r = [r.sub.e] Itfollows from the continuity of Nike air max 90 Noir Gris Blanc Femme,[www.airmax90chaussurespourfemme.com]
