我国上市银行外汇风险暴露的测度研究

伴随着金融全球化以及人民币国际化进程,商业银行作为外汇市场上的交易主体,其外汇风险暴露问题成为值得关注的问题。使用资本市场法对我国上市商业银行外汇风险暴露进行测度,结果表明我国50%的上市银行存在显著的外汇风险暴露,在人民币渐进升值、银行外汇资产迅速增加的背景下,我国上市银行需要加强对外汇风险的管理,提高稳健经营水平。     

跨国公司股东财富最大化与折算风险探讨

跨国公司折算风险的大小取决于在国外经营的程度与国外子公司所在地会计方法的选择。国际上大部分国家都根据子公司的类型选择折算方法。整体型子公司采用时态法,自主型子公司采用现行汇率法。折算方法要选择对合并利润最大化有利并设法使合并资产负债表上外币风险资产与外币负债趋于一致,以轧平净风险资产头寸,消除或减少因不可预期汇率变动而对公司现金流量与经济价值的影响。采取期货合同套期保值、远期合约套期保值、货币互换套期保值、货币期权套期保值的防范措施和规避方法,能使折算风险最小,股东财富最大化。     

Trade and the distribution of human capital

We develop a two-country, two-sector model of trade where the only difference between the two countries is their distribution of human capital endowments. We show that even if the two countries have identical aggregate human capital endowments the pattern of trade depends on the properties of the two human capital distributions. We also show that the two distributions of endowments also completely determine the effects of trade on income inequality. We also look at a simple majority voting model. It turns out autarky and free trade with and without compensation may be the voting outcome.     

Spurious welfare reversals in international business cycle models

Several papers have documented spurious welfare reversals: incomplete-markets economy produces a higher level of welfare than the complete-markets economy. This paper first demonstrates how conventional linearization can generate approximation errors that can result in welfare reversals. Using a two-country production economy, we argue that spurious welfare reversals are not only possible but also plausible under reasonable values for model parameters. This paper then proposes an approximation method that modifies the conventional linearization by a bias correction. This method can be easily implemented and approximates welfare as accurately as a second-order perturbation method.     

中国—东盟自由贸易区“10 1”方案的福利效应分析

中国—东盟自由贸易区的建立是双方加强经济合作的必然要求,同时也顺应了经济全球化和区域经济一体化的趋势,有利于双方更好地分享区域经济一体化所带来的好处。然而,当前我国和东盟各国的比较优势都集中在劳动密集型产品上,各成员国之间存在着较强的竞争性,自由贸易区建成后我国和东盟各国能否从中获得更大的利益?本文从福利经济学的角度出发,分析了建立“10 1”自由贸易区所可能产生的各种福利效应。     

Technological advances in digital cameras: Welfare analysis on easy-to-use characteristics

This paper examines the characteristics attributed to the success of digital cameras by studying both the demand and the supply sides of the digital-camera market. A discrete choice model is employed to investigate consumer preferences over digital camera characteristics during the period 1996–1998. The empirical findings reveal that Sony’s ‘Easy-to-Use’ storage system contributes significantly to Sony’s demand advantage and profitability. Also, the welfare analysis demonstrates that ‘Easy-to-Use’ attributes significantly contribute to social welfare improvement.

中美双边工业品增加值贸易隐含碳福利核算与分配问题研究

现代贸易方式不仅导致贸易利益在全球价值链上进行分配,还带来了贸易隐含污染排放在全球贸易网络中的分布。两国之间的贸易利益分配除了表现为贸易经济福利的分配,还表现为贸易隐含碳福利的分配。本文将贸易增加值分解法结合MRIO模型对2000—2014年中美双边工业品贸易增加值所隐含的碳福利分配及影响机制展开深入分析。研究结果表明:(1)在中美双边工业品增加值贸易隐含碳福利分配中,碳福利逆差在中国,碳福利顺差在美国;(2)中美工业品贸易碳福利级差经历了“先扩大,后收窄”的过程,美国次贷危机之后双边碳福利不平衡状况重新呈现扩大趋势;(3)中国碳排放强度下降、价值链地位提升以及对美进口规模扩大都有助于改善碳福利逆差的局面,但美国对中国不断扩大的中间品和最终品需求以及双边复杂的技术关联结构仍是中国碳福利逆差的主导因素;(4)全球价值链的深化可能将导致对出口国加征关税会通过降低进口消费侧排放的方式恶化加征国的贸易隐含碳福利。本文研究的时间范围同时覆盖中国加入WTO以及美国次贷危机两个重要节点,这对于重新审视中美经贸关系新格局下双边贸易隐含碳福利分配构建了一个新的分析视角,为中美未来贸易谈判以及全球碳排放责任认定提供了一个新的解读方向。     

Trade and financial liberalization with asymmetric information in bank financing

We investigate trade and financial openness in a small developing country where entrepreneurs need bank financing to operate in an import‐competing sector but banks do not observe their ability. This informational asymmetry causes adverse selection of low‐ability individuals into entrepreneurship and also prevents poor but able individuals from being entrepreneurs. We find that trade opening improves national welfare, but a tax is needed on foreign financial capital. Trade opening reduces an income gap between the rich and the poor, while financial opening affects this income gap ambiguously.
