Market impact: a systematic study of the high frequency options market

This paper deals with a fundamental subject that has seldom been addressed in recent years, that of market impact in the options market. Our analysis is based on a proprietary database of metaorders—large orders that are split into smaller pieces before being sent to the market—on one of the main Asian markets. In line with our previous work on the equity market [Said, E., Bel Hadj Ayed, A., Husson, A. and Abergel, F., Market impact: A systematic study of limit orders. Mark. Microstruct. Liq., 2018, 3(3&4), 1850008.], we propose an algorithmic approach to identify metaorders, based on some implied volatility parameters, the at the money forward volatility and at the money forward skew. In both cases, we obtain results similar to the now well-understood equity market: Square-Root Law, Fair Pricing Condition and Market Impact Dynamics.     

Traders’ choice between limit and market orders: evidence from NYSE stocks

In this paper, we examine a trader's order choice between market and limit orders using a sample of orders submitted through NYSE SuperDot. We find that traders place more limit orders relative to market orders when: (1) the spread is large, (2) the order size is large, and (3) they expect high transitory price volatility. A rise in informational volatility appears neither to increase nor decrease the placement of limit orders. We also find that a rise in lagged price volatility decreases the size of spread, which is driven by the increase in the placement of limit orders.     

The Procompetitive Effect of Demand-Enhancing Check-Off Programs

This article explores demand-enhancing check-off programs and how such programs may influence both private programs as well as industry market structure. Under duopoly, a firm may increase its sales through privately funding product quality improvements. However, such endogenous sunk costs may also be used to exclude a rival. Industry-funded check-off programs affect firms' strategies and can be procompetitive. The rationale lies not only in how the check-off enhancement is perceived by consumers but also in the way the check-off's crowding-out effect reduces the ability of a firm to use its private expenditures to bar a rival's market access.     

开放准入秩序与我国内资企业创新活动——基于动态面板模型的经验分析

本文将我国民营企业发展、国有企业产权制度改革、外商直接投资的扩大、内资企业参与全球分工的深化纳入到诺思的开放准入秩序的分析框架,运用动态面板数据模型进行检验得出:非国有经济的发展、内资企业参与国际分工以及外资企业的研发活动对内资企业的创新活动产生了激励作用,但强度不大;而在民营经济发达地区,通过提高非国有经济占比来增加创新激励的效果已不明显,但参与国际分工与外资企业的研发活动产生的作用均有所加强。

Some Properties of Past Entropy and their Applications

In the context of information theory, measure of uncertainty in past lifetime distribution has been proposed by Di Crescenzo and Longobardi (J Appl Probab 39:434–440, 2002). In this paper, we study some ordering and aging properties in terms of past entropy (based on past lifetime) and develop some characterization results. Some discrete distribution results are also addressed here.     

Order aggressiveness and order book dynamics

In this paper, we study the determinants of order aggressiveness and traders’ order submission strategy in an open limit order book market. Applying an order classification scheme, we model the most aggressive market orders, limit orders as well as cancellations on both sides of the market employing a six-dimensional autoregressive conditional intensity model. Using order book data from the Australian Stock Exchange, we find that market depth, the queued volume, the bid-ask spread, recent volatility, as well as recent changes in both the order flow and the price play an important role in explaining the determinants of order aggressiveness. Overall, our empirical results broadly confirm theoretical predictions on limit order book trading. However, we also find evidence for behavior that can be attributed to particular liquidity and volatility effects.

A tale of two Italies: ‘access-orders’ and the Italian regional divide

ABSTRACT

This paper uses the ‘access orders’ paradigm developed by North, Wallis, and Weingast [(2009). Violence and social order: A conceptual framework for interpreting recorded human history. Cambridge: Cambridge University Press] to analyse the case of the Italian North–South economic divide. In line with their framework, we collect and discuss several social and political indicators over the long-run, at the regional level. Firstly we looked at data on the pre-conditions for the establishment of an open-access order, such as murders per capita (a proxy for control over violence), voting turnout and referendums participation (proxies for political legitimacy), and the impersonality of exchange. We then showed evidence of different access orders in the North and in the South, using the information on human capital formation, women participation in the labour market, and referendum results. On the basis of this evidence, we argue that, despite being part of the same State and subject to the same formal institutions, the North of the country progressively developed into an open-access order, while the South remained a form of limited access order.

Institutional differences are linked to specific aspects of the economic performance of the two areas, thus the ‘access order’ paradigm appears to be an effective conceptual scheme to explain the North–South economic divide.

Disclosure, leaks, and slips: Issues and strategies for prohibiting employee communication

Both popular and social science literature are replete with recommendations for enhancing communication effectiveness, typically defined as improving the clarity and impact of the spoken and written word. However, managing internal organizational processes and external market competitiveness often requires a different communication strategy, specifically silence and non-disclosure, while adhering to statutory regulations. This article summarizes the rationale for communication prohibitions, highlights counter forces mitigating their intended effects, and offers recommendations for successful implementation. The three major counter forces are: employee motivation and perception, changing socio-cultural norms, and organizational structures reflecting virtual teams and project teams. The eight recommendations for combating these forces are subsumed under one of two categories: creating an organizational culture supporting prohibitions, and executing the prohibitions with a minimum of employee resistance. In summary, employees charged with maintaining secrecy and adhering to non-disclosure prohibitions must view those restrictions as reasonable, warranted, equitable, and legal.
