Liquidity Provision of Limit Order Trading in the Futures Market Under Bull and Bear Markets

Abstract:  This study investigates how limit orders affect liquidity in a purely order-driven futures market. Additionally, the possible asymmetric relationship between market depth and transitory volatility in bull and bear markets and the effect of institutional trading on liquidity provision behavior are examined as well. The empirical results demonstrate that subsequent market depth increases as transient volatility increases in bull markets. Market depth exhibits significantly positive relationship to subsequent transient volatility in bull markets. Additionally, although trading volume positively influences transient volatility in bull markets, no such relationship exists in bear markets. Liquidity provision decreases when institutional trading activity intensifies during bear markets. Thus, liquidity provision for limit orders differs between bull and bear markets.

The Diversification Discount Puzzle: Evidence for a Transaction-Cost Resolution

The literature on the corporate diversification discount and the relative efficiency of internal versus external capital markets provides mixed results. We argue that transaction-cost economics is useful in understanding this puzzle. According to transaction-cost economics, diversified firms should outperform single segment firms in industries with higher external transaction costs (e.g., emergent industries) and under-perform in industries with low external transaction costs and high agency and other internal costs (e.g., some mature industries). This paper provides evidence supporting these contentions.     

Why integrating purchasing with marketing is both inevitable and beneficial

The shift away from manufacturing in Western developed economies has resulted in economies in which service industries are dominant. Marketing itself has undergone a paradigmatic shift from a focus on the exchange of goods to the provision of capabilities. This paper examines the relationship between marketing and purchasing as a result of the shift from product- to capability-focused commerce. We suggest that the marketing and purchasing departments will become closer due to two major reasons. First, as marketers increasingly become solution-oriented rather than product-focused, they will need to source products and services from third-party vendors and will require deeper involvement of the purchasing department. Second, with the emergence of customer-centric marketing coupled with build-to-order manufacturing, marketing and purchasing will have to be better aligned to deliver solutions to customers. These new dimensions in the marketing–purchasing interaction will also lead to changes in the selection, training, and recruitment of marketers and purchasers as well as their roles in the supply chain. We elaborate on these changes likely to occur in business-to-business organizations and along with implications for managers.     

重构企业R＆D项目战略投资决策方法体系

传统的投资决策方法是一种建立在广泛应用的以货币的时间价值为基础的投资决策方法,它已越来越不能适应当今充满不确定性和竞争性的市场需要.实物期权方法比传统的折现现金流法（DCF）更适合来分析不确定条件下的投资决策问题,但仅凭实物期权方法还不能对不完全竞争环境下的企业R＆D项目战略投资问题进行准确分析和估价,而引入期权博弈理论恰好能克服这些缺陷.文章从理论上阐述了重构企业R＆D项目投资决策方法体系的可能性和必要性,并由此提出了研究的基本框架.     

企业战略投资的分类治理——基于交易治理期权观的视角

在不确定和竞争的环境下,企业战略投资价值实现方式的选择或治理模式的选择成为关系战略投资战略价值实现的根本问题。若基于交易成本理论来选择战略投资的治理模式,势必影响企业的重大战略时机和战略价值的实现;而基于期权观的治理理论来选择战略投资的治理模式,不但可以确保战略投资灵活性期权价值的实现,而且能最大化实现企业的战略价值。本文对企业的4类战略投资(技术研发投资、战略原料投资、战略市场投资、战略人力资本投资)的治理问题的具体分析证明了期权治理观的观点。     

内部资本市场功能异化与公司治理

内部资本市场缓解了企业集团的融资约束,提升了投资效率,但也增加了公司治理的难度。在缺乏有效公司治理机制的情况下,内部资本市场的功能部分地被异化为经理人寻租或控股股东进行“利益输送”的渠道。本文讨论了内部资本市场功能异化与公司治理的关系,分析了内部资本市场的部分功能异化的原因,提出了治理的建议。     

Did immigration contribute to wage stagnation of unskilled workers?

In this paper we first show that the timing and skill distribution of Immigrants to the U.S. between 1970 and 2014 imply they did not contribute to the decline in the wages of native, non-college educated workers – including high school dropouts – at the national level. We then review other evidence at the local level, which implies immigration is not associated with lower non-college wages. Rather, higher immigration seems associated with higher average (and college-level) wages. Local externalities, complementarities, efficient specialization and appropriate technological choice suggest at least part of the positive association is causal.     

From COVID-19 herd immunity to investor herding in international stock markets: The role of government and regulatory restrictions

We study if government response to the novel coronavirus COVID-19 pandemic can mitigate investor herding behaviour in international stock markets. Our empirical analysis is informed by daily stock market data from 72 countries from both developed and emerging economies in the first quarter of 2020. The government response to the COVID-19 outbreak is measured by means of the Oxford COVID-19 Government Response Tracker, where higher scores are associated with greater stringency. Three main findings are in order. First, results show evidence of investor herding in international stock markets. Second, we document that the Oxford Government Response Stringency Index mitigates investor herding behaviour, by way of reducing multidimensional uncertainty. Third, short-selling restrictions, temporarily imposed by the national and supranational regulatory authorities of the European Union, appear to exert a mitigating effect on herding. Finally, our results are robust to a range of model specifications.
