试论内部审计的风险及其防范

在现代企业制度下，虽然经济监督的主体应该是由社会审计组织所实施的外部公证性监督，但外部审计能否顺利运作，企业内部审计状况是一个非常重要的制约条件。内部审计是审计体系的重要组成部分，在国民经济监督中占有一定的位置，发挥着不可估量的作用。

Renegotiation Design and Contract Solutions to the Hold-Up Problem

Abstract.  This paper surveys the literature on contractual solutions to the hold-up problem which has addressed the issue of how to design the optimal contractual arrangement to achieve efficient investments in the presence of contract incompleteness. Although scholars have argued that renegotiation design is a necessary condition to avoid the hold-up problem, some recent papers have seriously questioned this condition. We mainly show that renegotiation design remains a necessary condition to implement efficient investments.

Tighter bounds in triangular systems

We study a nonparametric triangular system with (potentially discrete) endogenous regressors and nonseparable errors. Like in other work in this area, the parameter of interest is the structural function evaluated at particular values. We impose a global exclusion and exogeneity condition, in contrast to Chesher (2005), but develop a rank condition which is weaker than Chesher’s. The alternative rank condition can be satisfied for binary endogenous regressors, and it often leads to an identified interval tighter than Chesher (2005)’s minimum length interval. We illustrate the potential of the new rank condition using the Angrist and Krueger (1991) data.     

An experimental test of behavior under team production

This study reports experiments that examine behavior under team production and a piece rate. In the experiments, participants complete a forecasting task and are rewarded based on the accuracy of their forecasts. In the piece‐rate condition, participants are paid based on their own performance, whereas the team‐production condition rewards participants based on the average performance of the team. Overall, there is no statistically significant difference in performance between the conditions. However, this result masks important differences in the behavior of men and women across the conditions. Men in the team‐production condition increase their performance relative to men in the piece‐rate condition. However, this gap in male performances across conditions diminishes over the course of the experiment. In contrast, women in the team‐production condition show significantly lower performance than the women in the piece rate. As a consequence of these differences, men in the team‐production condition show significantly better performance than women in the team‐production condition. We also find evidence that men show stronger performance when they are in teams with a larger variation in skill level. Copyright © 2010 John Wiley & Sons, Ltd.     

A necessary and sufficient condition for an NTU fuzzy game to have a non-empty fuzzy core

In 2004, Predtetchinski and Herings [A. Predtetchinski, P.J.J. Herings, “A necessary and sufficient condition for non-emptiness of the core of a non-transferable utility game”, Journal of Economic Theory 116 (2004) 84–92] provided a necessary and sufficient condition for non-emptiness of the core of a non-transferable utility game. In this paper, we extend this theorem to its counterpart in fuzzy games and give a necessary and sufficient condition for a non-transferable utility fuzzy game to have a non-empty fuzzy core. As a consequence, we derive a necessary and sufficient condition for non-emptiness of the fuzzy core of a TU fuzzy game.     

The geometry of arbitrage and the existence of competitive equilibrium

We present the basic geometry of arbitrage, and use this basic geometry to shed new light on the relationships between various no-arbitrage conditions found in the literature. For example, under very mild conditions, we show that the no-arbitrage conditions of Hart [Journal of Economic Theory 9 (1974) 293] and Werner [Econometrica 55 (1987) 1403] are equivalent and imply the compactness of the set of utility possibilities. Moreover, we show that if agents’ sets of useless net trades are linearly independent, then the Hart–Werner conditions are equivalent to the stronger condition of no-unbounded-arbitrage due to Page [Journal of Economic theory 41 (1987) 392]—and, in turn, all are equivalent to compactness of the set of rational allocations. We also consider the problem of existence of equilibrium. We show, for example, that under a uniformity condition on preferences weaker than Werner’s uniformity condition, the Hart–Werner no-arbitrage conditions are sufficient for existence. With an additional condition of weak no-half-lines—a condition weaker than Werner’s no-half-lines condition—we show that the Hart–Werner conditions are both necessary and sufficient for existence.     

Equivalence of utilitarian maximal and weakly maximal programs

For a class of aggregative optimal growth models, which allow for a non-convex and non-differentiable production technology, this paper examines whether the set of utilitarian maximal programs coincides with the set of weakly maximal programs. It identifies a condition, called the Phelps–Koopmans condition, under which the equivalence result holds. An example is provided to demonstrate that the equivalence result is invalid when the Phelps–Koopmans condition does not hold.     

Local and global consistency properties for student placement

In the context of resource allocation on the basis of priorities, Ergin (2002) identifies a necessary and sufficient condition on the priority structure such that the student-optimal stable mechanism satisfies a consistency principle. Ergin (2002) formulates consistency as a local property based on a fixed population of agents and fixed resources—we refer to this condition as local consistency and to his condition on the priority structure as local acyclicity. A related but stronger necessary and sufficient condition on the priority structure such that the student-optimal stable mechanism satisfies a more standard global consistency property is unit acyclicity.
