　　五、报告摘要
　　We study continuous–time consumption and portfolio choice in the presence of Knightian uncertainty. We embed the problem into the framework of G-Brownian motion dealing in particular with the issue of non–equivalent multiple priors. The problem is completely solved by identifying the worst–case measure. The decision about participation in the asset market does not depend on volatility uncertainty. Our setup also allows to consider interest rate ambiguity; we show that under some robust parameter constellations, the investor optimally puts all his wealth into risky assets.
