Segment Reporting： Value and Policy Choice

Evidences indicate that segment reporting has the ability to forecast firms＇ performance and reflect risks of stock market. However, there is no consensus between IAS and FASB on the choice of policy for segment reporting. Based on the analysis of IAS and FASB＇s statements for segment reporting, this paper points out that industry and geography are the two vital bases for determining the segments, and internal organizational structure also should be taken into account. Before segment reporting, a primary segment needs to be identified, and others can be regarded as secondary segments. The information of the segments can be disclosed in the form of supporting statement. This paper also gives a concrete format of segment reporting.     

Bequests, Inter Vivos Transfers, and Wealth Distribution

This paper constructs a heterogeneous agent overlapping generations model with bequests and inter vivos transfers. In the model, households in the same family line behave strategically to determine their consumption, working hours, gifts, and savings. Calibrating the model to the U.S. economy, the paper measures time preference and parental altruism consistent with the economy's capital-output ratio and the size of intergenerational transfers. The model with intergenerational transfers better explains, although not fully, the wealth distribution of the United States. The paper also analyzes the effects of government policy changes on wealth accumulation, distribution, and social welfare.

Publicly Provided Private Goods and Redistribution: A General Equilibrium Analysis

Public provision of private goods is examined within a self-selection framework where production depends on labour supply of different households and the level of public provision. It is shown that productivity and wage-structure effects can create a role for public provision, even if preferences are weakly separable between goods and leisure. Public provision of education may offer an intuitively appealing case for the production-side impacts. We also address the reasons for public provision in a dynamic, overlapping generations economy, whereby public provision may affect efficiency and social costs of redistribution of future generations as well.

Specialization in a dynamic trade model: An overlapping generations case

Abstract

We explore a small open economy with overlapping generations to show that demographic structure is an important factor for the determination of a production pattern in the dynamic trade theory. In the representative agent model, Baxter (1992) shows that even if there are two commodities and two production factors, there is a Ricardian implication that opening up to trade leads to perfect specialization in a small open economy. In contrast, using the overlapping generations model, we find that the heterogeneity of the economic agents generally makes imperfect specialization occur. We also find that whether the stability condition holds or not is crucial for the determination of the long-run production pattern.     

Trade Union and Global Economic Growth

Abstract

This paper develops a simple framework for examining the role of unions in a global economy. It builds on the model of different institutions by comparing America with a flexible wage and Europe with a rigid wage (the existence of union), where the two areas are integrated via perfect capital mobility. We find the necessary condition that the degree of wage orientation of the union is larger than the firm's bargaining power and determines the positive direction on global economic growth. In addition, the effect of union's bargaining power on global economic growth is ambiguous. If the sum of the elasticity of substitution between capital and labour and the output elasticity of labour is smaller than one, or the firms are characterized by a Leontief production function (Harrod–Domar growth model) or an extremely low substituting elasticity (much empirical literature is supported), the union's bargaining power will lead to an increase in the growth of the global economy. In the general Cobb–Douglas production function (Solow–Swan neoclassical growth model), the union's bargaining power will result in a decline in the growth of the global economy.     

上海国内航空客运市场特征分析

为深入了解上海航空客运市场特征,在分析上海航空运输市场发展环境的基础上,根据需求规模将上海航空客运市场细分为快线、大客流、中客流和低客流四类,并对每类细分市场分别从总体规模、航线机型匹配以及收益水平进行定量分析。结果表明,快线市场需求巨大供给充足,市场格局已经形成,大客流市场表现不稳定,中客流市场规模小,收益水平一般,而低客流市场收益良好,市场前景广阔。最后,根据市场特征给出航空公司进入上海市场的策略性建议。     

中国绿色食品消费群体市场细分研究——基于修正的食品相关生活方式量表

在中国频繁发生食品安全问题的大环境下,食品安全消费的研究就显得十分重要。文章对西方背景下开发的食品相关生活方式量表进行适合中国市场和文化的修正,并基于修正量表对中国食品消费者进行市场细分,经过两步骤聚类分析得出5个细分市场,分别是“传统居家型”（7.5%）、“保守节约型”（16.6%）、“现代都市型”（19.5%）、“享乐探险型”（23.8%）、“淡漠便利型”（32.6%）,并从中识别出“享乐探险型”“保守节约型”“传统居家型”三个细分市场为绿色食品消费群体,“现代都市型”为潜在绿色食品消费群体,“淡漠便利型”为非绿色食品消费群体,最后根据不同细分市场的特点为绿色食品企业提供营销建议。     

税制改革、经济效率和社会福利——基于A-KOLG框架下的动态CGE模拟分析

在经典的世代交叠动态一般均衡(A-K OLG)模型的基础上,建立了一个由一系列不等式方程组所构成的"跨期动态"模型,反现实地模拟了提高间接税同时降低直接税对我国社会福利、经济效率的影响。与基期相比,减少对资本征税会带来福利增长0.34%(纯经济效率提高0.25%),减少对劳动征税会带来福利增长0.1%(纯经济效率提高0.02%)。该实证结果证明了间接税比直接税更有利于实现经济效率的理论观点。因此,提高直接税的比重是需要以一定的经济效率损失为代价的,实行该项举措应该权衡好各方面利弊、把握好改革时机。     

风险、保险与投资在跨期模型中的关系研究

为了解释保险在经济个体最优决策中的作用,并探讨影响保费的因素,文章通过在跨期模型中引入风险、保险和投资等变量,给出了保费、保险金额、预期投资收益率、风险分布及相关系数等关键因子的理论关系,论证了保险将影响最优的投资水平,个体可以通过保险增加价值,以及影响保费的三个因素。通过对中国保险数据的实证检验,验证了模型中影响保费的因素,并阐明了中国需要加大对经济个体的风险保障水平。     

Taxation, Bequests, and Short and Long Run Timber Supplies: An Overlapping Generations Problem

This paper uses an overlapping generations model with one-sided altruism to study the effects of several forest taxes that target bequests and affect timber supply. Unlike previous work, we investigate bequests and timber supply in both the short and long run when bequests are costly (e.g., taxed). The landowner's problem is examined in the short run, while the government's problem is examined in the long run assuming the existence of a steady state. We also consider taxes targeting harvests, growth, savings and bequests. Several new results are established concerning the interactions of taxes that might be used by a government to alter short and long run forest capital stocks: (i) the presence of a forest bequest tax affects the neutrality of harvest tax in both the short and long run, (ii) in the long run the bequest tax decreases bequests and timber supplies. When the bequest tax is not present, the capital income tax is neutral with respect to bequest and timber supply, while the harvest tax is neutral only if forest productivity is also not taxed. Finally, (iii) in the short run, the substitution and total effects of taxes in landowner decisions generally depend on the presence of the bequest tax. The results have implications for Pigouvian tax design and second best tax choice.
