跨文化交际与出口商品商标词研究

出口商品商标是中国企业、商家走向国际市场不可缺少的开拓工具。出口商品商标的宣传已成为各国在国际市场上推销商品和参与商业竞争的战略之一。本旨在通过分析我国出口商品商标词的构成，从跨化角度出发探讨中国出口商品商标词国际化的途径。     

Valuation by Simulation of Contingent Claims with Multiple Early Exercise Opportunities

This paper introduces the application of Monte Carlo simulation technology to the valuation of securities that contain many (buying or selling) rights, but for which a limited number can be exercised per period, and penalties if a minimum quantity is not exercised before maturity. These securities combine the characteristics of American options, with the additional constraint that only a few rights can be exercised per period and therefore their price depends also on the number of living rights (i.e., American-Asian-style payoffs), and forward securities. These securities give flexibility-of-delivery options and are common in energy markets (e.g., take-or-pay or swing options) and as real options (e.g., the development of a mine). First, we derive a series of properties for the price and the optimal exercise frontier of these securities. Second, we price them by simulation, extending the Ibáñez and Zapatero (2004) method to this problem.     

MULTIVARIATE SUBORDINATION OF MARKOV PROCESSES WITH FINANCIAL APPLICATIONS

This paper develops the procedure of multivariate subordination for a collection of independent Markov processes with killing. Starting from d independent Markov processes with killing and an independent d‐dimensional time change , we construct a new process by time, changing each of the Markov processes with a coordinate . When is a d‐dimensional Lévy subordinator, the time changed process is a time‐homogeneous Markov process with state‐dependent jumps and killing in the product of the state spaces of . The dependence among jumps of its components is governed by the d‐dimensional Lévy measure of the subordinator. When is a d‐dimensional additive subordinator, Y is a time‐inhomogeneous Markov process. When with forming a multivariate Markov process, is a Markov process, where each plays a role of stochastic volatility of . This construction provides a rich modeling architecture for building multivariate models in finance with time‐ and state‐dependent jumps, stochastic volatility, and killing (default). The semigroup theory provides powerful analytical and computational tools for securities pricing in this framework. To illustrate, the paper considers applications to multiname unified credit‐equity models and correlated commodity models.     

从“知假买假”现象引发的思考

近年,假冒伪劣商品的泛滥不仅损害着消费者的健康和财产利益,还扰乱了市场经济秩序,自《消费者权益保护法》实施以来,旨在打假的"知假买假"现象在日益发展的市场经济社会中可谓屡见不鲜,我们称之为"王海现象"。然而"知假买假"者是不是消费者、受不受《消费者权益保护法》的保护、能否适用《消费者权益保护法》第四十九条的规定等问题引起了社会各界的广泛争议。要整治假冒伪劣行为,仅靠几个职能部门来打假治劣是远远不够的,必须发动更多的群众和职业打假者来依法监督生产经营者。应该本着对知假买假者打假行为认可和鼓励的态度使之适用于《消费者权益保护法》。     

Twenty years of jumps in commodity markets

In this article, we provide statistical evidence around jumps affecting commodity returns. Using nearly 20 years of daily data, we use Laurent, Lecourt, and Palm's (2011) methodology to jump extraction, and discuss various aspects of the estimated jump activity. On average across various commodity markets, we find a high number of days for which returns exhibit the presence of jumps, consistently with the intuition that commodities are affected by large price fluctuations. We emphasize that the post-jump average return depends on the commodity sector considered (e.g. agriculture, energy, or metals). We also show evidence of a jump-to-volatility channel for commodities (similar to the effect usually found for equities). Finally, we diagnose around 40 dates during which commodity indices, stocks, bonds and currencies `co-jump’, revealing a tail dependence between standard and alternative assets.     

Speculation and volatility—A time-varying approach applied on Chinese commodity futures markets

Experts have long discussed and empirically investigated whether speculative activity increases volatility on commodity futures markets. Little empirical research, however, analyzes the role of speculators on commodity futures markets in China. Using time-varying vector autoregression models with stochastic volatility, this paper investigates for four heavily traded metal and agricultural contracts, how the relationship between returns volatility and speculation evolves over time. Our findings indicate that speculative activity has little to no impact on volatility. On the contrary, for all commodities examined, returns volatility seems to amplify speculation.     

中国与海合会双边贸易的实证研究——兼论建立双边自贸区的对策

海合会是中国重要的贸易伙伴,也是中国最主要的石油进口来源地,是中国重要的货物出口市场.本文旨在研究中国与海合会的双边贸易关系,为中国海合会自贸区谈判提供理论依据.运用贸易结合度指数、可显示比较优势指数和出口相似度指数等指标进行了实证分析,发现中国与海合会双边贸易的比较密切;海合会国家在绝大多数产品生产上没有比较优势,中国具有比较优势的产品很多,双方的出口商品结构互补性很强,双方贸易竞争性很弱.自由贸易区建立以后,不会因为双边贸易的扩张导致任何一方产业受损.中国政府应加快双边自贸区谈判,并考虑签署投资自由化协议,促进双边能源产业相互投资;中国企业应积极拓展海合会商品市场,发展对海合会服务出口.     

我国物流市场的现状及发展对策

我国物流市场虽有一定的发展,但总体上,仍处于起步阶段,存在着企业物流发展滞后,物流人才短缺等问题.发展我国的物流市场,应以工业企业为核心,发展第三方物流,注入第四方物流,同时大力培养物流人才,以满足物流市场发展对人才的需要.     

Volatility Forecasting and Time‐varying Variance Risk Premiums in Grains Commodity Markets

In this paper we examine empirically the predictive power of model‐free option‐implied variance and skewness in wheat, maize and soybeans derivative markets. We find that option‐implied risk‐neutral variance outperforms historical variance as a predictor of future realised variance for these three commodities. In addition, we find that risk‐neutral option‐implied skewness significantly improves variance forecasting when added in the information variable set. Variance risk premia add significant predictive power when included as an additional factor for predicting future commodity returns.
