In this paper, we introduce the notion of a linked domain and prove that a non-manipulable social choice function defined on such a domain must be dictatorial. This result not only generalizes the Gibbard-Satterthwaite Theorem but also demonstrates that the equivalence between dictatorship and...

It is often assumed that financial markets are frictionless. Bond markets are illiquid and bond prices are observed with errors. The magnitude of these errors leads to violation of no--arbitrage conditions and, consequently, prevents researchers from obtaining an estimate of the term structure...

Based on measurements among 332 owner-managers, we investigate how the global shape of the utility function (i.e., S-shaped versus concave or convex over the total range of outcomes) relates to choice behavior. We find that the global shape of the utility function differs across decision makers...

New results are presented for the wavevector-dependent susceptibility of Z-invariant periodic and quasiperiodic Ising models in the scaling limit, generalizing old results of Tracy and McCoy for the square lattice. Explicit results are worked out for the two leading singular terms of the...

The standard loss function gives the same weight to positive and negative deviations from the output and inflation targets. This short note criticizes this symmetry assumption. If the period covered is long enough output growth in excess of the target, and often also inflation rates that are...
