企业价值评估方法研究

企业价值评估诸多方法中,现金流指标的重要性日益显现,其中,自由现金流量最具可行性。企业规模 的大小、发展的阶段和经营的盈亏成为影响企业现金流的基本内因,而季节性、周期性和竞争是其外因。企业价值评 估从企业历史业绩分析开始,再预测未来绩效,并评估连续价值,最终确定企业价值总额。

自由软件开发的模块化理论解释与启示

本文以GNU/Linux为例讨论了源代码的内部结构在自由软件开发中所起的重要作用。为此,我们考虑了源代码的模块化属性。源代码的模块化将直接影响开发者是否参与对自由软件的开发。基于模块化的自由软件开发不仅实现了劳动的分工,同时也实现了劳动价值的分割,在自由软件的开发过程中较好地解决了搭便车问题。同时,模块化理论对我国发展软件产业也有一定的借鉴作用。     

Country asymmetry,trade agreements,and transfers

Using a standard 2 × 2 trade agreement model, I show that the welfare effects of a free trade agreement (FTA) depend on the asymmetry on supply and demand functions. When countries are sufficiently asymmetric with respect to the size or the demand functions, the small country tends to be better off, while the large country is worse off. Thus, the small country must compensate the large country for the FTA to be incentive‐compatible. However, in the presence of sufficient asymmetry in the supply functions, the small country is worse off, while the bigger is better off. In this case, the transfer must flow from the large to the small country. This last finding helps explain why some FTAs between rich and poor countries provide for adjustment transfers to the latter.     

The determinants of FTA use in Southeast Asia: A firm-level analysis

The spread of free trade agreements (FTAs) in Southeast Asia has ignited a debate about their impact on enterprises including the business costs from the Asian ‘noodle bowl’ effect. This paper undertakes a comparative and firm-level analysis of the determinants of FTA use in Indonesia, Malaysia and the Philippines. The likelihood of firms using important ASEAN+1 FTAs (e.g. the ASEAN-China FTA, the ASEAN-Japan FTA and ASEAN-Korea FTA) is positively associated with acquiring knowledge about FTAs, building technological capabilities, and membership in industrial clusters. Non-use of FTAs is explained by a lack of information about FTAs and the absence of FTAs with major trading partners. Key policy implications are the need to improve business support for FTAs, to conclude FTAs with major trading partners, and to create a database on FTA preference use.

Tariffs and formation of free trade agreements networks

This paper examines the formation of bilateral free trade agreements (FTAs) on the basis of country heterogeneity in the tariff level. We demonstrate that a country's unilateral incentive to form an FTA depends on the relative magnitudes of the (negative) market concession effect and the (positive) market expansion effect, both of which are determined by the tariff levels of the two FTA partner countries. Global welfare is maximised when all country pairs form FTAs. Two countries in equilibrium are more likely to form an FTA when their tariff gap is smaller or when their tariff levels are neither very high nor very low. This finding is robust to several extensions of the model. Our preliminary empirical analysis provides some evidence for the finding.
