[We study the simultaneous impact of fiscal policy decisions on macroeconomic activity, wealth distribution, and asset prices. We consider a general equilibrium, overlapping generations model with incomplete markets and heterogeneous agents, where government debt and capital are imperfect substitutes. Increases in public debt lead to significant increases in the riskless rate and to a reduction in the equity premium, while higher capital income tax rates lead to a higher equity premium. The crowding-out effects (on capital and output) are much higher than in models where government debt and capital are perfect substitutes, which thus ignore households' portfolio reallocation decisions.]

The empirical pricing kernels estimated from index options are non-monotone (Rosenberg and Engle, 2002, Bakshi et al., 2010) and the corresponding risk-aversion functions can be negative (Aït-Sahalia and Lo, 2000, Jackwerth, 2000). We show theoretically that these and several other properties of empirical pricing kernels are consistent with rank-dependent utility model with probability weighting function, which overweights tail events. We also estimate the pricing kernels nonparametrically from the Standard & Poor's 500 index options and construct empirical probability weighting functions. The estimated probability weights typically have the inverse-S shape, which overweights tail events and is widely supported by the experimental decision theory.
