There is a typesetting error in the first equation of Results section d. In the article, the (incorrect) equation reads:

$${\psi }_{T_s|a}(\tau )=\mathbb{E}[{\text{e}}^{\tau T_s}|a]=\mathbb{E}[e^{\tau T_s}{V}_s,a|a]=\mathbb{E}[{\psi }_{T_s|V_s,a}(\tau )|a].$$

It should read as:

$$\begin{array}{rl}{\psi }_{T_S|a}(\tau )& =\mathbb{E}[{\text{e}}^{\tau T_S}|a]=\mathbb{E}[\mathbb{E}[{\text{e}}^{\tau T_S}|V_S,a]|a]\\ & =\mathbb{E}[{\psi }_{T_S|V_S,a}(\tau )|a].\end{array}$$
