Exploring the design of conscious media

Our existing model of media, based upon a consumptive-materialist–atomistic orientation, falls short in seeking to promote mainstream awareness of systemic and integral thinking in society-at-large. This paper presents evolutionary guidance media, a new model for media arising from evolutionary perspectives including systems science, humanistic, transpersonal and integral studies designed to promote planetary consciousness and give rise to an ecological–spiritual–integral mindset. Two key elements of evolutionary guidance media are discussed: a databank containing purposeful data from nine or more dimensions of human activity, and transception, the infusion of cyberception with qualities arising from mutual causality. Specific types of transception are introduced including Gaiaception, Agoraception, and Dharmaception. Organizations and companies already in the process of creating green media, socially responsible media, and spiritual, or transformational media are vanguards of the development of conscious media.

PRICING ASIAN OPTIONS FOR JUMP DIFFUSION

We construct a sequence of functions that uniformly converge (on compact sets) to the price of an Asian option, which is written on a stock whose dynamics follow a jump diffusion. The convergence is exponentially fast. We show that each element in this sequence is the unique classical solution of a parabolic partial differential equation (not an integro‐differential equation). As a result we obtain a fast numerical approximation scheme whose accuracy versus speed characteristics can be controlled. We analyze the performance of our numerical algorithm on several examples.     

基于期权定价理论的风险投资决策

项目评价的传统方法———净现值(NPV)法在应用于风险投资项目时,由于低估了投资价值,往往会使得投资者失去一些有价值的投资机会。结合风险投资的特性,将期权定价理论应用于风险投资决策中,并建立连续及离散两种状态下的决策模型

Is the January effect still alive in the futures markets?

The January effect concerns the fact that small capitalization stocks have historically outperformed large capitalized stocks in January. We analyze evidence as to whether this anomaly can be exploited in the futures markets as a speculative investment or to add risk-adjusted value to portfolio performance. We find that the January effect is still alive in the futures markets on the Value Line minus S&P 500 spread trade, but that the marginal liquidity of the Value Line stock index futures contract has made it very risky to exploit the effect. Historically from 1982/3 to 2004/5, the trade has been profitable. This anomaly was also exploitable through a Russell 2000 minus S&P 500 spread trade from 1993/4 to 2004/5.

Machine learning for pricing American options in high-dimensional Markovian and non-Markovian models

In this paper we propose two efficient techniques which allow one to compute the price of American basket options. In particular, we consider a basket of assets that follow a multi-dimensional Black–Scholes dynamics. The proposed techniques, called GPR Tree (GRP-Tree) and GPR Exact Integration (GPR-EI), are both based on Machine Learning, exploited together with binomial trees or with a closed form formula for integration. Moreover, these two methods solve the backward dynamic programing problem considering a Bermudan approximation of the American option. On the exercise dates, the value of the option is first computed as the maximum between the exercise value and the continuation value and then approximated by means of Gaussian Process Regression. The two methods mainly differ in the approach used to compute the continuation value: a single step of the binomial tree or integration according to the probability density of the process. Numerical results show that these two methods are accurate and reliable in handling American options on very large baskets of assets. Moreover we also consider the rough Bergomi model, which provides stochastic volatility with memory. Despite that this model is only bidimensional, the whole history of the process impacts on the price, and how to handle all this information is not obvious at all. To this aim, we present how to adapt the GPR-Tree and GPR-EI methods and we focus on pricing American options in this non-Markovian framework.     

Real call options to enlarge foreign subsidiaries – The moderating effect of irreversibility on the influence of economic volatility and political instability on subsequent FDI

This paper develops a real option model to explain the decision of enlarging a new foreign subsidiary by subsequent investment. The model is tested on a panel of 1148 subsidiaries in 22 host countries. The findings complement the traditional process model of firm internationalization. Rather than abiding by an incremental pattern of investment, internationalizing firms seem to keep foreign investment strategies flexible and build up their subsidiaries contingent upon the interaction of economic volatility and irreversibility of investment. However, the moderating effect of irreversibility on the relationship between uncertainty and investment may not hold for downside risks such as political instability.
