Merging art and design in foresight: Making sense of Emerge

Emerge: Artists and Scientists Redesign the Future, hosted by Arizona State University in 2012, united artists, engineers, bioscientists, social scientists, storytellers and designers to build, draw, write and play with the future. Over three days, and in nine different workshops, participants created games, products, monuments, images and stories in an effort to reveal the texture and feel of emergent futures. The Emerge workshops drew from a burgeoning field of future-oriented methods that infuse art, design and information technology into the development and delivery of scenarios and design fictions – a constellation of practices I call “mediated scenarios”. This introduction and the articles in this special issue, work to make sense of these emerging practices, and of Emerge itself, in order to develop appreciation of this rising genre. In doing so, the papers in this issue ask critical questions about the nature of these novel forms of foresight practice and investigate the trade-offs and potencies involved in the workings of mediated scenarios.     

Efficient market hypothesis and fraud on the market theory a new perspective for class actions

Following recent judgment of the Supreme Court of US (June 2014), several commentators had declared that “Securities class actions are here to stay” (insidecounsel.com—September 2014, 11). This paper provides a critical perspective on this judgment, which “implicates substantive issues at the intersection of economic theory, financial markets, and securities regulation” (128Harv. L. Rev. 291 2014–2015, 291), and shows that we must be much more careful. This recent judgment is based on the Fraud on the Market Doctrine, which was introduced in 1973 in order to preserve the class action procedure in securities fraud litigation. The characteristic of the Fraud on the Market Doctrine is to have been structured from one of the most popular financial theory: Efficient Market Hypothesis. In this paper, by analysing the implementation of the Efficient Market Hypothesis in Fraud on the Market Theory, we argue that if the Supreme Court had to take position for a second time about the Fraud on the Market Doctrine it is due to the practical difficulties inherited from Efficient Market Hypothesis and that have raised several problems to the US courts, including the Supreme Court. This issue is illustrated by the definition of Efficient Market Hypothesis lawyers used (“most” vs “all”/“fully”). As this paper shows, if “Securities class actions are here to stay”, the opportunity to open such a class action is strongly reduced in the facts.     

A perspective on systems science and systems philosophy

A philosophical survey of systems science and systems philosophy is offered to provide an integrated, if personal, view of the ideas within the contemporary systems movement. An attempt is made to establish the validity of the two disciplines by meeting some of the criticisms levelled at the systems paradigm—particularly Sir Karl Popper's attacks on holistic thought. During the discourse the arguments that rage around reductionism and holism will be seen to contain some confused thinking, and it is suggested that the philosophy, theories and methods in systems science and systems philosophy offer a means for bringing reductionism and holism into a satisfactory alliance.     

The investigation of the dynamic linkages between real estate market and stock market in Greece

ABSTRACT

We use quarterly data from Greece over the period 1997:1–2015:2 and investigate the dynamic linkages between the price of the real estate market and the price of the stock market focusing on two transmission mechanisms, namely the wealth and credit-price effects. The empirical analysis employs advanced methodological techniques and presents evidence supporting the existence of both the wealth effect and the credit effect in the long-run while in the short-run there is a one-way causal effect running from stock market towards house market. Results reveal asymmetric adjustment to equilibrium process and considerably stronger for positive deviations from the equilibrium.     

A network perspective of comovement and structural change: Evidence from the Chinese stock market

How to appropriately characterize the comovement between any pair of individual stocks and describe the market comovement structure is a great challenge and plays a key role in understanding emerging markets. This paper applies the complex network approach to deal with this issue for the Chinese stock market. Firstly, in view of the topological properties, we investigate the time-varying comovement between individual stocks by constructing 14 directed weighted stock networks. Furthermore, the weighted LeaderRank algorithm is employed to describe the comovement structure of the entire market. Most importantly, from the perspective of fundamental factors and industry factors, we reveal the driving factors of the comovement and structural change of the entire market. The empirical results suggest that: (i) Stocks with higher weighted LeaderRank algorithm scores generally have more long-term investment value; and the so-called views, “too big to fail” and “too connected to fail”, are further confirmed. (ii) ROE, BMratio and Growth are significantly positively correlated with the comovement between individual stocks, and Mvalue is significantly negatively correlated during normal periods. However, during the crisis, the signs of regression coefficients of above four explanatory variables are reversed. (iii) In normal periods, we only find that the agriculture, forestry, animal husbandry & fishery and composite have significant influence on the comovement structure of the entire market. Besides, public utilities and medias also have a significant impact during the crisis. In addition, a very interesting fact in point is that network density, average clustering coefficient, and global efficiency can provide an “early warning” for possible upcoming crises.     

Evaluation of the adaptive market hypothesis as an evolutionary perspective on market efficiency: Evidence from the Tehran stock exchange

This study evaluates the existence of the adaptive market hypothesis (AMH) as an evolutionary alternative to the efficient market hypothesis (EMH) by applying daily returns on the TEPIX index in the Tehran stock exchange (TSE) in Iran. The data span of daily returns is from 1999 to 2013. In this paper four different tests in the form of two distinguished classes (linear and nonlinear) have been used to study adaptive behavior of returns. The results that were obtained from linear (automatic variance ratio and automatic portmanteau) and nonlinear (generalized spectral and McLeod–Li) tests represent the oscillatory manner of returns about dependency and independency which corresponds with the adaptive market hypothesis.     

The dynamic relationship among the money market mutual funds,the commercial paper market,and the repo market

In this paper, we present the short-run and the long-run relationships among the financial assets of the money market funds, the commercial paper market, and the repurchase agreement market by undertaking a cointegration analysis of quarterly data over the 1985–2017 period. This was based on the empirical observation that the commercial paper and repo markets account for 50 percent of the assets of money market funds. The evidence suggests that there exists a common long-term cointegrating trend among these three components of the shadow banking system. Any disequilibrium in this long-run relationship among these variables is corrected by movement in the financial assets of money market funds. The Beveridge-Nelson decomposition from the estimated cointegrating relationship shows that the cyclical component of money market funds is large and captures huge swings in these markets during the financial crisis. We also find evidence of change in these dynamic relationships in the post-crisis period, where in addition to the money market funds, the commercial paper market also exhibits a tendency to correct for the disequilbrium.     

房地产市场运行及未来趋势展望

2011年在以限购为主的房地产调控政策作用下,市场需求受到抑制,商品房销售增速明显低于历史同期平均水平。保障性住房全年开工建设任务已经提前完成,受其拉动,房地产开发投资保持高位。当前,保障性住房建设全面展开,以限购为主的调控政策短期不会退出,并呈现向二三线城市扩大的趋势,一些前期房价上涨过快的城市降价促销愈演愈烈,商品房价格回调趋势明显。

A dynamic limit order market with fast and slow traders

This paper considers the role of high-frequency trading in a dynamic limit order market. Fast traders? ability to revise their quotes quickly after news arrivals helps to reduce the inefficiency that is rooted in the risk of being picked off, which increases trade. However, their presence induces slow traders to strategically submit limit orders with a lower execution probability, thereby reducing trade. Because speed is a source of market power, it enables fast traders to extract rents from other market participants and triggers a costly arms race that reduces social welfare. The model generates a number of testable implications concerning the effects of high-frequency trading in limit order markets.     

Options, short-sale constraints and market efficiency: A new perspective

This paper undertakes a new investigation of the potential for options to mitigate short-sale constraints. I find that option introduction alleviates 79% of the price adjustment efficiency disparity between short-sale constrained and unconstrained stocks in relation to negative news. No significant improvement in adjustment efficiency is found in response to positive information. These results are robust to controls for endogeneity biases associated with the option introduction selection process. Further, I find evidence that post-option improvement in efficiency is similar in relation to private and public information. This suggests that short-sale constraint effects stem, at least in part, from an irrational, optimism bias or another behavioral source as suggested theoretically by Miller (1977). Collectively, these results suggest that options act as an effective substitute to short-sales, significantly contributing to the informational efficiency of the market.
