# Kreps Porteus Certainty Equivalent Intuition

In Epstein-Zin recursive preferences, the Kreps-Porteus certainty equivalent is defined by $$$$\mathcal{R}_t(V_{t+1}) = (\mathbb{E}_t V_{t+1}^{1 - \gamma})^{1 /(1 - \gamma)}.$$$$ where $$\gamma$$ governs risk aversion and $$V_{t+1}$$ is utility tomorrow, as opposed to some level of consumption.

Is there some reason/intuition for taking a certainty equivalent of utilities rather than bundles that has something to do with Epstein-Zin? Is it due to the preference over the timing of resolution? Thanks!
