摘要翻译:
在平衡问题的激励下,我们证明了一类具有二次非线性且间断的马尔可夫倒向随机微分方程在$Z$中解的存在性。利用唯一连续性和向后唯一性,我们证明了间断集具有测度零点。在一个连续时间的禀赋经济随机模型中,我们证明了具有非退化内生波动的不完全Radner均衡的存在性。

英文摘要:
Motivated by an equilibrium problem, we establish the existence of a solution for a family of Markovian backward stochastic differential equations with quadratic nonlinearity and discontinuity in $Z$. Using unique continuation and backward uniqueness, we show that the set of discontinuity has measure zero. In a continuous-time stochastic model of an endowment economy, we prove the existence of an incomplete Radner equilibrium with nondegenerate endogenous volatility.
