An approach for designing a menu of comprehensive income products for retirement (CIPRs) is proposed and demonstrated. The approach entails for steps: defining and characterising member types based on selected attributes; specifying a utility function to capture the objectives and preferences of...

In this paper, we relax the restriction on the identical distribution for the random utility parts under discrete choice models. The derived new choice model can allow more flexible substitution pattern, and has the potential to describe choice behavior more accurately. If an alternative's...

This paper takes seriously that the quasilinear utility model is an approximation. We interpret approximation error as arising because individuals are satisficers. We investigate the consequences of individual satisficng for modelling aggregate demand, providing an approximate aggregation...

The St. Petersburg paradox is the oldest paradox in decision theory and has played a pivotal role in the introduction of increasing concave utility functions embodying risk aversion and decreasing marginal utility of gains. All attempts to resolve it have considered some variants of the original...

We study portfolio selection in a complete continuous-time market where the preference is dictated by the rank-dependent utility. As such a model is inherently time inconsistent due to the underlying probability weighting, we study the investment behavior of sophisticated consistent planners who...

In this paper we use the property that certainty equivalence, as implied by a first-order approximation to the solution of stochastic discrete-time models, breaks in its equivalent continuous-time version. We study the extent to which a first-order approximated solution built by perturbation...

Using a revealed preference approach, we conduct an experiment where subjects make choices from linear convex budgets in the domain of risk. We find that many individuals prefer mixtures of lotteries in ways that systematically rule out expected utility behavior. We explore the extent to which...

This paper theoretically derives a general utility function for inferior goods that accounts for the utility derived from both the quality and the quantity aspects of goods in a model with two substitutable consumption goods. We show the conditions under which a good becomes a normal, an...

The efficient-market hypothesis (EMH) is one of the most important economic and financial hypotheses that have been tested over the past century. Due to many abnormal phenomena and conflicting evidence, otherwise known as anomalies against EMH, some academics have questioned whether EMH is...
