需求多样化下非会计专业本科会计学教学改革探索 总被引:4,自引:0,他引:4
本文从对学生和社会本科会计学教学需求的调查中发现,社会与学生对本科会计学教学的需求具有多样性。这种多样性导致了严格的教学学时限制与教学内容丰富性要求的矛盾,难以简单地以增加授课内容的方式来满足。教学实践表明,在主要传授会计学基础内容的前提下,适当引导学生进行形式多样、内容丰富的自主学习,是解决这一矛盾的有效方式。 相似文献

Summary. We show the existence of a competitive equilibrium in an economy with many consumers whose preferences may change over time. The demand correspondence of an individual consumer is determined by the set of subgame-perfect equilibrium outcomes in his intrapersonal game. For additively separable preferences with concave period utility functions that are unbounded above, this demand correspondence will satisfy the usual boundary conditions. Whenever consumers can recall their own mixed actions, this correspondence is convex-valued. This ensures the existence of a symmetric competitive equilibrium.Received: 29 July 2004, Revised: 17 November 2004, JEL Classification Numbers:

The Monetary Policy of the European Central Bank 总被引:3,自引:0,他引:3

The first six years of ECB monetary policy are examined using a general framework that allows central bankers to weight differently positive and negative deviations of inflation, output and the interest rate from their reference values. The empirical analysis on synthetic euro‐area data suggests that the objective of price stability is symmetric, whereas the objectives of real activity and interest‐rate stabilizations are not. Output contractions imply larger policy responses than output expansions of the same size, while movements in the interest rate are larger when the level of the interest rate is relatively high. The hypothesis of M3 growth‐rate targeting is rejected. 相似文献

We incorporate Stone–Geary preferences into an overlapping generations economy under pure exchange, and explore stability, indeterminacy, and cycles with positive levels of saving and nonnegative public debt. A stable nontrivial steady state exists for parameter values, for which there does not exist equilibrium in the model with purely logarithmic utility function. We also show the possibility of a period-doubling bifurcation (a two-cycle). 相似文献

The paper considers what can be inferred about experimental subjects’ time preferences for consumption from responses to laboratory
tasks involving tradeoffs between sums of money at different dates, if subjects can reschedule consumption spending relative
to income in external capital markets. It distinguishes three approaches identifiable in the literature: the straightforward
view; the separation view; and the censored data view. It shows that none of these is fully satisfactory and discusses the
resulting implications for intertemporal decision-making experiments.

Summary. We show, in the Choquet expected utility model, that preference for diversification, that is, convex preferences, is equivalent
to a concave utility index and a convex capacity. We then introduce a weaker notion of diversification, namely “sure diversification.”
We show that this implies that the core of the capacity is non-empty. The converse holds under concavity of the utility index,
which is itself equivalent to the notion of comonotone diversification, that we introduce. In an Anscombe-Aumann setting,
preference for diversification is equivalent to convexity of the capacity and preference for sure diversification is equivalent
to non-empty core. In the expected utility model, all these notions of diversification are equivalent and are represented
by the concavity of the utility index.

The objective of this study is to determine factors influencing brand preferences of wine consumers in the Marmara region
where viniculture and wine production is so important in Turkey. First, the consumers’ preferences survey has been conducted
with 1022 persons in the region randomly selected and evaluated. Then, the informative factors influencing brand preferences
collected in these surveys have been determined by the multinomial logit model. A lot of independent variables have been used
in the multinomial logit model, but, because some independent variables were not found as significant according to Likelihood
Ratio test, these variables are not included in the multinomial logit analysis. Six important factors influencing wine brand
preferences have been determined. These factors are brand change causes of consumers, occupation of consumers, marital status
of consumers, birthplace of consumers, income of consumers and gender of consumers. In addition, whether the wine brand preferences
are independent, has been tested with Testing Independence of Irrelevant Alternatives of Hausman. According to this test,
it has been found that the wine brand preferences are independent. 相似文献

We explore the interaction between evolutionary stability and lexicographic preferences. To do so, we define a limit Nash equilibrium for a lexicographic game as the limit of Nash equilibria of nearby games with continuous preferences. Nash equilibria of lexicographic games are limit Nash equilibria, but not conversely. Modified evolutionarily stable strategies (Binmore and Samuelson, 1992. J. Econ. Theory 57, 278–305) are limit Nash equilibria. Modified evolutionary stability differs from “lexicographic evolutionarily stability” (defined by extending the common characterization of evolutionary stability to lexicographic preferences) in the order in which limits in the payoff space and the space of invasion barriers are taken. 相似文献

This paper investigates the impact of divergent consumer confidence on option prices. To model this, we assume that consumers
disagree on the expected growth rate of aggregate consumption. With other conditions unchanged in the discrete-time Black–Scholes
option-pricing model, we show that the representative consumer will have declining relative risk aversion instead of the assumed
constant relative risk aversion. In this case all options will be underpriced by the Black–Scholes model under the assumption
of bivariate lognormality.

信息不对称、管理者内生偏好与上市公司股权融资偏好 总被引:2,自引:0,他引:2
一般以为,上市公司的股权融资偏好是由于不合理的成本因素、有缺陷的监管制度和政策与低效的资本市场等原因造成的.本文分析认为,上市公司股权融资偏好产生的基本原因是管理者的内生融资偏好.如果公司绩效影响管理者的财富(或职位、声誉等),管理者的偏好将支配公司的融资决策;对称信息下,管理者将有充分的股权融资偏好.不对称信息下,如果管理者对公司项目(或资产)拥有私人信息,且厌恶风险,管理者将最大限度地使用股权融资,直至达到均衡.最后,本文提出,管理者对股权融资的偏好是内生的,治理目前上市公司股权融资偏好所产生危害的基本思路是"疏",而不是"堵". 相似文献
