Fiscal Policy and Asset Prices with Incomplete Markets
研究了在不完全市场和异质性代理人条件下，财政政策（公共债务和资本所得税）如何同时影响宏观经济、财富分配和资产价格，发现债务与资本的不完全替代性放大了挤出效应。
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.
