网络环境下会计信息系统审计的风险及其防范

一、网络环境下会计信息系统审计的风险 会计信息系统审计（AIS Audit）指“通过一定的技术手段收集并评估证据,以判断一个会计信息系统是否做到安全、可靠和有效,同时又能最经济的使用资源”。这一定义既包括信息系统的外部审计的鉴证目标——即对被审计单位的会计信息系统安全性和可靠性的审查,又包含内部审计的管理目标——即不仅包括被审计会计信息系统安全性和可靠性而且包括会计信息系统的有效性和效率性目标。

VOLATILITY STRUCTURES OF FORWARD RATES AND THE DYNAMICS OF THE TERM STRUCTURE1

For general volatility structures for forward rates, the evolution of interest rates may not be Markovian and the entire path may be necessary to capture the dynamics of the term structure. This article identifies conditions on the volatility structure of forward rates that permit the dynamics of the term structure to be represented by a two-dimensional state variable Markov process. the permissible set of volatility structures that accomplishes this goal is shown to be quite large and includes many stochastic structures. In general, analytical characterization of the terminal distributions of the two state variables is unlikely, and numerical procedures are required to value claims. Efficient simulation algorithms using control variates are developed to price claims against the term structure.     

我国海外并购中潜在法律风险探微

近年来,我国企业纷纷以跨国并购的方式向海外输出资本。随着年并购额的逐年攀升,盲目注重并购规模和数量的劣势已初露端倪;另一方面并购技术的稚嫩和对海外并购潜在法律风险的忽视使得我国企业在并购中屡遭挫败。目前学界已经开始对海外并购法律风险和规避措施进行系统研究。本文拟从反垄断法和劳工标准两方面阐述其法律风险的产生原因及应对措施,并对海外并购法律风险的不可预测性及发展趋势进行初步探究。

QUASI-LINEAR UTILITY FUNCTIONS AND THE DYNAMICS OF PURE EXCHANGE OVERLAPPING GENERATIONS MODELS

This paper considers the dynamics of pure exchange OLG models with stationary population (each agent living for two periods), tastes and endowments, homogeneous agents and well behaved preferences. It is shown that any kind of dynamics that can emerge from this class of models can be generated by a subclass of models where preferences are described by quasi-linear utility functions.     

INCOME DISTRIBUTION,TECHNICAL CHANGE AND THE DYNAMICS OF INTERNATIONAL ECONOMIC INTEGRATION

This paper explores the features of a dynamic multisectoral model that focuses on the relationship between income distribution, growth and international specialization. The model is explored both for the steady‐state properties and the transitory dynamics of integrated economies. Income inequality affects the patterns of growth and international specialization as the model uses non‐linear Engel curves and hence different income groups are characterized by different expenditure patterns. At the same time income distribution is also reflected in the relative wage rates of skilled to unskilled workers, i.e. the skill premium, and hence the wage structure affects comparative costs of industries which have different skill intensities. The model is applied to a situation that analyses qualitatively different economic development strategies of catching‐up economies (a ‘Latin American’ scenario and a ‘East Asian’ scenario).     

HYSTERESIS IN THE DYNAMICS OF EMPLOYMENT

In this paper, we derive a micro model of employment demand with hysteresis whereby firms can adjust along an intensive (employment) and an extensive (hours of work) margin. A mechanism of aggregation over heterogeneous firms is used to generate the corresponding aggregate dynamics. Longitudinal micro monthly data on a representative sample of Portuguese manufacturing firms are used in the empirical analysis. Our results indicate that signs of hysteresis found at the micro level do not vanish completely by aggregation and that hysteresis is magnified by the existence of an additional margin of adjustment (the hours adjustment margin).     

THE EVOLUTIONARY DYNAMICS OF FINANCIAL PRACTICES

This paper presents a model in which financial practices are chosen by decentralized units on the basis of expectations regarding financial market conditions, while the probability distribution governing market conditions itself depends on the choices made. If all agents are unboundedly rational, there is a unique equilibrium in which expectations are self-fulfilling. The assumption of universal unbounded rationality is relaxed by introducing an optimization cost, which leads to the possibility that optimizers may not have a sufficiently great evolutionary advantage to eliminate nonoptimizers entirely. In this case behavioral heterogeneity can persist even in the long run. For certain classes of probability distributions governing financial conditions, the evolutionary dynamics of population composition can help explain a number of stylized facts regarding the dynamics of financial practices which have hitherto been explained on the basis of learning dynamics or systematic cognitive biases.
