会计稳健性根源探析

利益相关者之间的信息不对称是会计稳健性产生的根本原因。损失函数的不对称包括契约性的和非契约性的。遭受损失的契约方会向管理当局和非契约方寻求帮助以降低其损失,准则制定机构和法律制定机构会分别制定更加稳健的会计准则以及执行严格的法律法规,从而保证处于信息劣势方不发生损失或者降低损失程度。准则以及各项法律法规在一定程度上形成了外部公司治理机制,从而产生了会计稳健性。     

水泥稳定碎石的作用原理及在公路施工中的应用

Agent-based simulation of consumer purchase behaviour based on quality,price and promotion

ABSTRACT

This paper studies the influence factors in consumer purchase behaviour. First, through reading and analysing the related paper, the authors summarise a lot of influence factors. Second, combined with the theme of the study, experts and scholars discuss these influence factors and choose quality, price and promotion of commodity as the object of this paper. Third, this paper presents an agent-based model and simulation method on the consumer purchase behaviours based on quality, price and promotion of commodity. The utility function is used to describe the model, which is implemented under NetLogo simulation environment. The results show that the proposed model can analyse and predict the effects of different quality, price and promotion strategies by the emergence of consumer purchase behaviour.     

A note on forecasting the prices of gold and silver: Asymmetric loss and forecast rationality

Given that the prices of gold and silver have witnessed large and substantial swings in recent years, policymakers and investors need readily available and reliable forecasts of the prices of these two precious metals. Survey data of forecasts of the prices of gold and silver provide a particularly rich data environment for policymakers and investors to study developments in the markets for gold and silver. Our research helps to develop a deeper understanding of the properties of survey data of the prices of gold and silver. We study the shape of forecasters’ loss function and the rationality of their forecasts. Assuming an asymmetric loss function weakens evidence against forecast rationality, but results depend on the empirical model being studied.

Accounting for optimism and pessimism in expected utility

We provide a preference foundation for decision under risk resulting in a model where probability weighting is linear as long as the corresponding probabilities are not extreme (i.e., 0 or 1). This way, most of the elegance and mathematical tractability of expected utility is maintained and also much of its normative foundation. Yet, the new model can accommodate the extreme sensitivity towards changes from 0 to almost impossible and from almost certain to 1 that has widely been documented in the experimental literature. The model can be viewed as “expected utility with the best and worst in mind” as suggested by Chateauneuf, Eichberger and Grant (Chateauneuf, Alain, Eichberger, Jürgen, Grant, Simon, 2007. Choice under uncertainty with the best and worst in mind: NEO-Additive capacities. Journal of Economic Theory 137, 538–567) or, following our preference foundation, interpreted as “expected utility with consistent optimism and pessimism”.     

Equivalence of optimal noisy-ranking contests and Tullock contests

We analyze a noisy-ranking contest in which participants compete in several dimensions. The organizer randomly samples a number of dimensions and awards a prize to the most productive agent. When the contest is optimally designed, we establish a structural equivalence between this family of noisy-ranking contests and contests built upon Tullock contest success functions. Our result also shows that in this class of noisy-contests, the profit-maximization problem of the planner can be turned into a stochastic choice problem for a planner who has some deterministic preferences over the contestants’ win probabilities.
