Risk and time are intertwined. The present is known while the future is inherently risky. This is problematic when studying time preferences since uncontrolled risk can generate apparently present-biased behavior. We systematically manipulate risk in an intertemporal choice experiment. Discounted expected utility performs well with risk, but when certainty is added common ratio predictions fail sharply. The data cannot be explained by prospect theory, hyperbolic discounting, or preferences for resolution of uncertainty, but seem consistent with a direct preference for certainty. The data suggest strongly a difference between risk and time preferences. (JEL C91 D81 D91)

Can the well-known experimental phenomenon of present-bias in intertemporal choice be confounded with the risks associated with receiving payment? Can measurements of risk preferences be used to represent desires for smoothness in intertemporal payments? In our two 2012 papers in this journal we explored these two questions and found the answer to the first to be yes and the second to be no. We feel the three papers inspired by our work and published here underscore these arguments and point to interesting new possibilities for modeling and measuring risk over time. (JEL C91, D81, D91)

Theorists of justice have to steer between two rocks. On the one hand, there is the intuition that an individual's morally permitted preferences should be respected: it is not justifiable to intervene with them. On the other hand, such preferences are the result of formation processes, which are notoriously vulnerable to manipulation. Does justice demand respect for preferences that produce or perpetuate injustices, suffered either by the individual herself or by others? In this paper, I will investigate this problem in the context of the ambiguous tenet of neutrality. The field of gender justice has extended Rawlsian theories of justice in order to account for structural factors, such as socialisation. Some theorists have argued that the justice-inhibiting character of some preferences implies that the first intuition should be rejected in favour of the second in some cases, which leads to the conclusion that some preferences are like obstacles standing in the way of justice and should thus be reformed. I will call this the 'Normative Hierarchy View' and argue that it is problematic. It presupposes a certain attitude with respect to those who hold the preferences, which forecloses a politically salient kind of respect. Furthermore, at the
