A set of su¢ cient conditions for representability of preference orders on real sequence spaces is analyzed. In particular, monotonicity and continuity of the order is not assumed. Two applications are worked out to demonstrate how such a result might be useful. Jel Codes: C60, D01

JEL Classification Code(s): J 31, J 71) "Perceptions of Discrimination, Effort to Obtain Psychological Balance, and Relative Wages: Can We Infer a Happiness Gradient?" There is a substantial literature that finds a linkage between happiness and relative economic well being as measured by earnings or wages. There is also a well documented racial gap in wages. One explanation for this is disparat...

A series of sphere-rod shape amphiphiles, in which a [60]fullerene (C60) sphere was connected to the center of an oligofluorene (OF) rod through a rigid linkage (OF-C60), were designed and synthesized. Alkyl chains of various lengths were attached onto the OFs on both sides of the C60 spheres. These compounds, denoted as alkyl-OF-C60, were fully characterized by (1)H NMR, (13)C NMR, and FTIR sp...

Water-soluble C60-porphyrin hybrid molecules were first synthesized toward their pharmaceutical applications.

Scanning tunneling microscopy (STM) was used to study the C60 adsorption on the Si rich (3x3) and C rich (43x43) surface of 6H-SiC(0001). At room temperature, triangular or hexagonal islands commensurating to the substrate structure at submonlayer coverages were observed. One of the interesting observations was the nucleation of the second layer of the C60 molecule^ even at submonlayer coverage...

The infraredand Raman-active vibrational modes of C60 were measured in the various structural states of Rb1C60. According to earlier studies, Rb1C60 has an fcc structure at temperatures above ∼ 100◦C, a linear chain polymer orthorhombic structure when slowly cooled, and an as yet undetermined structure when very rapidly cooled (“quenched”). We show that the spectra obtained in the polymer state...

This paper analyzes the problem faced by a risk-averse firm considering how much to invest in a risky project. The firm receives a signal about the value of the project. We derive necessary and sufficient conditions on the signal distribution such that (i) the agent’s investment is nondecreasing in the realization of the signal, and (ii) different signals can be ranked according to their ex ant...

A generalized version of the capital management problem posed in a classic paper by R. H. Strotz is analyzed for the case of the “naive” planner who fails to anticipate any impending change in his own preferences. By imposing progressively stronger restrictions on the primitives of the problem — namely, the planner’s discounting function, his utility index function, and the investment technolog...

Superconducting behavior even under harsh ambient conditions is expected to occur in La@C60 if it could be isolated from the primary metallofullerene soot when functionalized by CF3 radicals. We use ab initio density functional theory calculations to compare the stability and electronic structure of C60 and the La@C60 endohedral metallofullerene to their counterparts functionalized by CF3. We f...

The study of asset price characteristics of stochastic growth models such as the riskfree interest rate, equity premium and the Sharpe ratio has been limited by the lack of global and accurate methods to solve dynamic optimization models. In this paper a stochastic version of a dynamic programming method with adaptive grid scheme is applied to compute the above mentioned asset price characteris...
