Impact of Regional Economic Integration in East Asia

The current study evaluates the economy wide impact of trade liberalization in the ASEAN region along with China, Japan and Korea (ASEAN + 3) by the year 2020 using the GTAP framework. The study also assesses the environmental impact of the trade liberalization in the region focusing on the seven environmental indicators (CO₂, CH₄, N₂O, BOD, COD, Suspended Solid and Industrial Waste). The result shows that the countries under agreement (ASEAN + 3) will benefit with increased output, expansion of trade and welfare due to trade reforms. Further, the integration will increase the global welfare, although the regions not under agreement in the world will show a decline in output growth. Vietnam will be gaining with the highest output growth among the ASEAN region; however, the impact on the environment would not be favourable. The environmental impact reveals a mixed outcome for participating countries under the agreement. The paper provides useful insight in pursuing greater trade liberalization among the countries under the study.     

The representation of American options prices under stochastic volatility and jump-diffusion dynamics

This paper considers the problem of pricing American options when the dynamics of the underlying are driven by both stochastic volatility following a square-root process as used by Heston [Rev. Financial Stud., 1993, 6, 327–343], and by a Poisson jump process as introduced by Merton [J. Financial Econ., 1976, 3, 125–144]. Probability arguments are invoked to find a representation of the solution in terms of expectations over the joint distribution of the underlying process. A combination of Fourier transform in the log stock price and Laplace transform in the volatility is then applied to find the transition probability density function of the underlying process. It turns out that the price is given by an integral dependent upon the early exercise surface, for which a corresponding integral equation is obtained. The solution generalizes in an intuitive way the structure of the solution to the corresponding European option pricing problem obtained by Scott [Math. Finance, 1997, 7(4), 413–426], but here in the case of a call option and constant interest rates.

北美自由贸易区经济周期协动性的实证研究

自《北关自由贸易协议》签订并实施以来,美国、加拿大、墨西哥三国间的经贸联系日益密切。三国间经贸投资联系的加强必然会作用于三国宏观经济波动的传导,并改变北美自由贸易区内美、加、墨三国经济周期协同的特点。本文首先探讨了《北美自由贸易协议》对美国、加拿大、墨西哥三国间贸易与投资的积极效应,然后对三国在北美自由贸易区成立前后的经济周期协动性变化的特征事实进行了分析,最后考察并检验了《北美自由贸易协议》对三国间经济周期协动性的影响。     

International R&D Rivalry with Spillovers and Tariff Policies

This paper investigates the effects of R&D spillovers on the R&D choices of foreign exporters when the importing country adopts either uniform or discriminatory alternative tariff regimes. We show that the importing country should optimally choose a uniform tariff regime. A uniform tariff regime is also advantageous for foreign exporters if the R&D spillovers are sufficiently large. A comparison of free trade with the two tariff regimes reveals that there are some situations in which both the importing country and foreign exporters are better off under free trade, which supports trade liberalization.

基于自由现金流量假说的盈余管理动因研究——来自中国上市公司的经验证据

基于代理成本理论及自由现金流量假说分析框架,研究了我国上市公司自由现金流量引发的盈余管理行为,并以2004~2006年我国A股上市公司为样本,运用面板数据分析方法进行了相应的实证研究。研究发现,自由现金流的代理成本是激发我国上市公司管理者进行盈余管理的重要原因;企业债务对自由现金流引发的盈余管理行为具有一定的抑制作用,但债务的软约束现象仍然存在。     

The Creation,Maintenance and Governance of Public Goods and Free Goods

The theory of public goods is largely irrelevant to their management and governance. It is highly normative but is unused in the policy area. It remains centred on highly idealized and dichotomized characteristics (non-rivalrousness and non-excludability) of public goods despite important theoretical progress in the last twenty years. It is suggested that public goods are as much social as technological constructions, but there is no explanation of how such goods come into existence. It is argued that they are often subject to evolution that changes the balance of their characteristics between being public or private goods. Present theory bears little relationship to the governmental budgetary processes assumed necessary to finance such goods, yet all management and maintenance costs, often high enough to deter such funding, are ignored. While there is recognition that the intensive use of a public good often imposes costs directly upon users, there is no corresponding recognition either that inappropriate and intensive usage can erode public goods as assets or that such usage is difficult to control. Free goods are described and mooted as specific and important types of public goods. Illustrative examples of public and free goods, mainly from Australia and the Pacific, are cited.     

Religion, longevity, and cooperation: The case of the craft guild

When the mortality rate is high, repeated interaction alone may not sustain cooperation, and religion may play an important role in shaping economic institutions. This insight explains why during the fourteenth century, when plagues decimated populations and the church promoted the doctrine of purgatory, guilds that bundled together religious and occupational activities dominated manufacturing and commerce. During the sixteenth century, the disease environment eased, and the Reformation dispelled the doctrine of purgatory, necessitating the development of new methods of organizing industry. The logic underlying this conclusion has implications for the study of institutions, economics, and religion throughout history and in the developing world today.     

全球经济衰退背景下的中印自由贸易区建设——基于实证的研究

中国和印度作为世界上最大的两个发展中国家,相互间经贸合作稳步推进,已互为对方的对外贸易、投资和经济交流的重要伙伴。在全球经济衰退的大背景下,"龙象"合作对包括两国和全球在内的三方都是有好处的。本文通过对双方经济开放度、贸易结合度、贸易竞争性与经济互补性、以及贸易量与GDP之间关系的实证研究,计算了GDP对贸易额的弹性系数,分析表明,中印两国构建自由贸易区不仅具有现实的政治经济基础,更是在日益恶化的世界经济环境下中印和世界的理性选择,只有中印两国携手,才可以稀释衰退的负面影响。     

INTRAINDUSTRY SPECIALIZATION AND THE UNITED STATES–CENTRAL AMERICA–DOMINICAN REPUBLIC FREE TRADE AGREEMENT

This paper examines changes in intraindustry specialization indicators over the 1992–2004 period to assess the potential for structural adjustment problems that may arise in the United States with growth in trade resulting from the United States–Central America–Dominican Republic Free Trade Agreement (CAFTA‐DR) between the United States and six Central American countries—Guatemala, Honduras, El Salvador, Nicaragua, Costa Rica, and the Dominican Republic. CAFTA‐DR will expand market access for US exporters. Few US industries are likely to encounter structural adjustment problems. Given the relatively large size of the US economy, and the small number of industries that face potential adjustment pressures, the United States should have liberalized all trade immediately. When potential adjustment pressures are indicated, long tariff phaseouts, complex rules of origin, and import safeguards are used to delay factor adjustments in import‐sensitive industries.
