浅谈资本运营中的风险管理

资本运营活动会带来未来收益的不确定性。而这种不确定性主要源于环境的不确定性。其表现主要有资本运营操作者对环境的认识能力有限和环境自身的动态变化。企业资本运营风险管理的基本方法主要有风险规避、风险控制、风险隔离、风险转移、风险分散等方法。企业不仅要及时识别资本运营中存在的风险,还需要建立一套风险管理机制,即建立风险报告、考评制度和企业财务风险防范制度,从而加强资本运营风险的控制。     

Robust Event Studies for Derogation from Suspension of Concentrations in Greece during the Period 1995–2008

This paper examines the possible effect of the derogation from suspension of concentrations by the Hellenic Competition Commission (HCC) on the stock performance of the requested companies. For this reason, we examined 16 companies listed in the Athens Stock Exchange (A.S.E) that are involved to 13 requested derogations from suspension during the period 1995–2008 by applying and assessing the results of three different event study methodologies (market model, mean adjusted return model and market adjusted return model). From the empirical findings, we conclude that the argument of the requested companies concerning the subsequent negative effect on their stock performance if the derogation from suspension by the HCC is delayed or not granted does not hold. On the contrary, the average abnormal and cumulative returns of the requested companies are positive and statistical significant. In addition, the results of the three event study methodologies are robust.     

Barcode Empires: Politics,Digital Technology,and Comparative Retail Firm Strategies

Like other service sectors, information technology has dramatically altered the growth and character of the retail trade sector in the affluent economies. Nevertheless, significant variation exists in the typical strategies of retail firms in different countries. This article explores this variation and proposes an explanation for why retailers achieved scale and solved their make, buy, and partner decisions along such different trajectories. It argues that national bases for scale retailing were shaped by a series of political negotiations starting in the 1960s and 1970s. This demonstrates once again that technology implementation is rarely determined by the technology itself, but more often by social and political rules. Future technology platforms, such as web-based or mobile commerce, should be expected to follow similar political logics. As multinational retailing firms spread around the globe, this has important implications for national competition policy.     

Value Capture and Policy Design in a Digital Economy

Pervasive information and communication technology (ICT), intertwined with global dispersion of supply chains, is inducing a sizable structural transformation. All the articles in this special issue highlight that even though technology is the key driver, the reactions of businesses and countries to these transformations will depend on economic, political, and social arrangements within each organization and society. The competitive landscape of the ICT industry itself is likely to remain in flux. Also in other industries, both value creation and value capture are becoming increasingly complex—and remain more favorable for the developed countries than some commonly used measures suggest. According to the prevailing economic thinking, public policies should set market-friendly “rules of the game” and then stay out of the way. In the ICT domain, technical standards, spectrum allocations, and market power associated with various types of lock-ins play crucial roles calling for more active public involvement. In particular, the dynamic aspects of competition and anti-trust policies are important yet complex. While there is limited scope for sectoral or horizontal industrial policies, this special issue provides alternative avenues for considering matrix or systemic policies emphasizing education, openness, and national competitiveness.

Minimax price bounds in incomplete markets

This paper develops an approach to tighten the bounds on asset prices in an incomplete market by combining no-arbitrage pricing and preference-based pricing, and the approach is applied to a call option in the absence of dynamic rebalancing. With the no-arbitrage pricing, it is straightforward to obtain the initial bounds, which are too wide to be of practical uses. By accepting that a representative agent exhibits risk aversion from a benchmark pricing kernel, it is possible to narrow the bounds considerably. Using the unbiased minimax deviation implicit in the parameters, one can restrict further the set of reasonable values on assets in incomplete markets.     

Monday returns and asset pricing

The seasonal patterns observed on Monday stock returns are still unexplained by different asset pricing models. We attempt to fill this gap in the finance literature by using the Fama-French (Journal of Financial Economics 33:3–56, 1993) risk factors to explain the Monday seasonal. The results in the study show that Monday returns are explained by risk factors such as the market return, the size of the firms, and the book-to-market ratios of firms.
