A Jump-diffusion Model for Exchange Rates in a Target Zone

We propose a simple jump-diffusion model for an exchange rate target zone. The model captures most stylized facts from the existing target zone models while remaining analytically tractable. The model is based on a modified two-limit version of the C OX , I NGERSOLL and R OSS (1985) model. In the model the exchange rate is kept within the band because the variance decreases as the exchange rate approaches the upper or lower limits of the band. We also consider an extension of the model with parity adjustments, which are modeled as Poisson jumps. Estimation of the model is by GMM based on conditional moments. We derive prices of currency options in our model, assuming that realignment jump risk is idiosyncratic. Throughout, we apply the theory to EMS exchange rate data. We show that, after the EMS crisis of 1993, currencies remain in an implicit target zone which is narrower than the officially announced target zones.     

AIG在次贷危机中所扮演的角色及其启示

美国的次贷危机已经演变成波及全球的金融危机，在此次危机中有许多国际知名的金融企业陷入困境，其中就包括美国国际集团（AIG）。作为全球首屈一指的保险业巨头，AIG在次贷危机中由于流动性不足，从一家纯粹的私人企业变成了“半国有化”的企业，其根源在于制度层面的投资过度集中、风险管理缺失、创新工具滥用，和技术层面的数据充足性、假设准确性、模型有效性等问题。     

The assignment of call option rights between partners in international joint ventures

We examine call option rights as a contractual clause in international joint ventures (IJVs) and propose that the assignment of the call option right in an IJV is determined by certain ex ante asymmetries between the partners. Results show that between the two partners in an IJV, the firm with greater complementarity with the venture and greater prior IJV experience is more likely to hold the call option right; in addition, the firm's contractual choice on the call option right and its ownership choice on a greater initial equity stake are substitutive. Our focus on explicit call options advances the real options theory of collaborative agreements, and our results also highlight that option rights be considered an important part of alliance design.

PRICING CHAINED OPTIONS WITH CURVED BARRIERS

This paper studies barrier options which are chained together, each with payoff contingent on curved barriers. When the underlying asset price hits a primary curved barrier, a secondary barrier option is given to a primary barrier option holder. Then if the asset price hits another curved barrier, a third barrier option is given, and so on. We provide explicit price formulas for these options when two or more barrier options with exponential barriers are chained together. We then extend the results to the options with general curved barriers.     

Pricing the Chicago Board of Trade T-Bond futures

The aim of this paper is to investigate the pricing of the Chicago Board of Trade (CBOT) Treasury-Bond futures. The difficulty in pricing it arises from its multiple inter-dependent embedded delivery options, which can be exercised at various times and dates during the delivery month. We consider a general Markov diffusion process model for stochastic interest rates and propose a pricing algorithm that can handle all the delivery rules embedded in the CBOT T-Bond futures. Our procedure combines dynamic programming, finite-elements approximation, and fixed-point evaluation. Numerical illustrations are provided under the one-factor Vasicek and Cox–Ingesoll–Ross models, and under the time in-homogeneous Hull–White model.     

The Differential Value Relevance of S&P's Core Earnings Versus GAAP Earnings: The Role of Stock Option Expense

In 2002, Standard & Poor's (S&P) introduced Core Earnings as a proprietary, uniform earnings metric, with the goal of improving financial reporting. The distinguishing feature of Core Earnings is its consistent treatment of seven adjustments to GAAP earnings for which there is no consensus adjustment by managers and analysts. We use stock price and return data to assess whether investors perceive Core Earnings to be more value relevant than GAAP earnings. The implementation of FASB 123R changed the calculation of GAAP and Core Earnings. This change allows us to assess the role of stock option expense in the valuation of earnings numbers by partitioning the sample into pre‐ and post‐FASB 123R periods and creating consistent measures of GAAP and Core Earnings. Our price results indicate that Core Earnings is more value relevant than GAAP earnings in the pre‐period after controlling for stock option expense, and in the post‐FASB 123R periods. The price results provide empirical evidence consistent with S&P's expectation that a uniformly calculated earnings measure is a more consistent and useful indicator of current performance and future earnings.     

权变视角下现代企业激励机制研究

传统激励理论以人的共性为出发点,忽视了不同个体问的差异性及情境因素的影响,激励效果较差.权变激励针对个体特殊性、情境多样性和社会复杂性,通过情感激励、按需激励、培训激励、股票期权激励等几种运行方式,以动态、多维的新视角寻找激励结构中各种关系的最佳匹配,从而优化激励过程,提高激励的有效性.     

Economic development lessons from and for North American Indian economies*

This paper reviews the literature on economic development as it relates to indigenous people in the United States and Canada, and focuses on how institutions affect economic development of reservation and reserve economies. Evidence shows that strong property rights to reservation and reserve land and natural resources, whether communal or individual, are and always have been important determinants of productivity. Political and legal institutions that are perceived as stable and predictable to tribal members and to non‐Natives also improve economic opportunities for indigenous people living on reservations and reserves. Research reviewed here also shows that culture and acculturation are important in the development process. Although our emphasis is on North America, the findings are applicable to indigenous people in other parts of the world and shed light on growth questions that loom large for developing countries around the world.     

Bounds on European Option Prices under Stochastic Volatility

In this paper we consider the range of prices consistent with no arbitrage for European options in a general stochastic volatility model. We give conditions under which the infimum and the supremum of the possible option prices are equal to the intrinsic value of the option and to the current price of the stock, respectively, and show that these conditions are satisfied in most of the stochastic volatility models from the financial literature. We also discuss properties of Black–Scholes hedging strategies in stochastic volatility models where the volatility is bounded.
