A jump-diffusion approach to modelling vulnerable option pricing

Following the framework of Klein [1996. Journal of Banking and Finance 20, 1211–1229], this paper presents an improved method of pricing vulnerable options under jump diffusion assumptions about the underlying stock prices and firm values which are appropriate in many business situations. In contrast to Klein [1996. Journal of Banking and Finance 20, 1211–1229] model, jumps can be used to model sudden changes in stock prices and firm values. Further, with the jump risk, a firm can default instantaneously because of an unexpected drop in its value. Therefore, our model is able to provide sufficient conceptual insights about the economic mechanism of vulnerable option pricing. The numerical results show that a jump occurrence in firm values can increase the likelihood of default and reduce the vulnerable option prices.

高管政治背景与民营企业盈利能力的实证研究

本文以我国2003—2007年在沪深交易所上市的民营企业为样本,实证研究了政治关系对民营企业盈利能力的影响,结果发现,高管的政治背景对公司盈利能力有显著的正面影响。进一步的研究还发现,高管的地方政治背景对公司盈利能力的正面影响要比中央政治背景的影响显著,而且董事长（副董事长）的政治背景对公司盈利能力的正面影响要比总经理的政治背景的影响显著。这些结果表明,政治关系是一种有价值的资源,有利于民营企业的发展。     

我国“双反”措施的产业救济效果与福利效应——基于可计算局部均衡COMPAS模型的研究

本文利用可计算局部均衡COMPAS模型,基于2005～2009年我国鸡肉产品生产与进口的有关数据,就我国对美国白羽肉鸡产品反倾销、反补贴税的产业救济效果、福利效应等进行了实证模拟。模拟结果表明:在未来5年里,我国对美国白羽肉鸡产品的反倾销、反补贴税将使我国白羽肉鸡行业的产量和就业增加近26%,销售收入增加38.4%;但是,"双反"措施也将导致我国市场鸡肉价格大约上涨9.8%,消费量下降2.8%,消费者福利损失近10亿美元。     

石油企业增值税存在的问题及建议

国家对石油企业征收增值税，在理论和实践中尚存在一些问题。从石油企业增值税的实际运行情况看，生产型增值税对石油企业的适用程度低，增值税税负高于国内外水平，增值税与营业税、所得税重复征收等。建议对石油行业增值税的税率由17%下降至13%，对陆上石油行业实行消费型增值税试点，使增值税的征收适合我国的国情和促进经济的发展。     

The Hong Kong Fish Marketing Organization

This essay provides an explanation of the phenomenon of an apparent secular fall in captured fisheries outputs in Hong Kong transacted through the Fish Marketing Organisation. The latter is a government monopoly, with the power to compel sale of landed fish through its licensed buyers, established and protected by law. The institutional characteristic of this organisation can also explain the evolution of marine fish culture industry in the area that is not subject to the forced‐sale regulation of the Organisation, and the diversity of species commonly observed in the consumer market of cultured fish. The observed reduction in fisheries output in Hong Kong can be the consequence of regulation rather than a lack of regulation, as the ‘the tragedy of commons’ would seem to imply. Our analysis also demonstrates why the Fish Marketing Organisation has suffered from a growing budgetary deficit in recent years.     

浅析城市政体理论的发展与运用

城市的发展早已经不仅仅是物质层面、经济层面上的问题。随着城市规模的不断扩大和城市人群的日趋多元化,更多的城市问题被理解成为社会问题、政治问题。城市研究者把眼光转向城市内部,通过观察城市政府的政治行为,探索社会经济活动中政治结构的存在和发展规律。城市政体理论(UrbanRegimeTheory)即为探索该问题的理论流派。本文意在介绍这一思潮的基本思想、理论根源和发展历程,以及其在中国语境下的解读和运用。

Efficiency Wages and Nominal Income Targeting in an Open Economy

Abstract. This paper considers the choice between nominal income and money supply targeting in an open economy with efficiency wages. The results show that, when real unemployment benefits are rigid, both nominal income and money supply targeting have the same stabilizing performance. On the contrary, if nominal unemployment benefits are rigid, then we come to a conclusion that either in the face of goods demand shocks or aggregate supply shocks, a sufficient condition for nominal income targeting to be preferable is that the income elasticity of money demand be less than unity.     

Banks’ capital buffer,risk and performance in the Canadian banking system: Impact of business cycles and regulatory changes

Using quarterly financial statements and stock market data from 1982 to 2010 for the six largest Canadian chartered banks, this paper documents positive co-movement between Canadian banks’ capital buffer and business cycles. The adoption of Basel Accords and the balance sheet leverage cap imposed by Canadian banking regulations did not change this cyclical behavior of Canadian bank capital. We find Canadian banks to be well-capitalized and that they hold a larger capital buffer in expansion than in recession, which may explain how they weathered the recent subprime financial crisis so well. This evidence that Canadian banks ride the business and regulatory periods underscores the appropriateness of a both micro- and a macro-prudential “through-the-cycle” approach to capital adequacy as advocated in the proposed Basel III framework to strengthen the resilience of the banking sector.
