This paper characterizes the optimal first-price auction (FPA) and second-price auction (SPA) for selling rights, contracts, or licenses that involve ensuing payoff uncertainty for the winning bidder. The distribution of the random payoff is common knowledge, except that bidders have private...

The second welfare theorem and the core-equivalence theorem have been proved to be fundamental tools for obtaining equilibrium existence theorems, especially in an infinite dimensional setting. For well-behaved exchange economies that we call proper economies, this paper gives (minimal)...

We prove existence of a competitive equilibrium in a version of a Ramsey (one sector) model in which agents are heterogeneous and gross investment is constrained to be non negative. We do so by converting the infinite-dimensional fixed point problem stated in terms of prices and commodities into...

We provide a nonparametric 'revealed preference' characterization of rational household behavior in terms of the collective consumption model, while accounting for general (possibly non-convex) individual preferences. We establish a Collective Axiom of Revealed Preference (CARP), which provides...

Searching for sustainable regional trade agreements (RTAs) for East Asia, we quantitatively evaluated the likely impact of proposed East Asian RTA strategies─(i) the AFTA (a being-left-alone strategy), (ii) an ASEAN Hub RTA (a hub-and-spoke type of overlapping RTA strategy), (iii) the AFTA vs...

We present the results of an experiment measuring social preferences within couples in a context where intra-household pay-off inequality can be reduced at the cost of diminishing household income. We measure social norms regarding this efficiency-equality trade-off and implement a cross-country...

The paper analyzes nonlinear tax schedules that are identified by maximizing a welfare function represented by a weighted summation of net utilities over a set of n=3 differing individuals. We demonstrate that some of the feasible and Pareto efficient tax schedules that satisfy self-selection...

When rational risk-averse agents must choose among and share monetary risks, it is known that efficient sharing is typically nonlinear, even with common beliefs. Wherever it is, the sharing rule may affect the choice, randomized choice may allow everyone to gain, and indeed a randomized choice...
