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.  相似文献

This paper considers the Web as a big data container that can be used by Technology Observatories and administrations to track emerging issues and more specifically emerging technologies. It considers information that is available on the Internet for free from different sources, and proposes a framework that can be useful to characterise them and to detect patterns of dissemination. This framework is made up of 30 metrics obtained from different kinds of sources (general web, patents, scholars?…). Some of them are obtained directly as the number of hits retrieved by queries on a search engine, and other ones calculated by means of ratios. This paper contains the development of a complete case that utilises this framework to characterise emerging technologies included in the well-known Hype Cycle for Emerging Technologies, in this case the 2015 release1 and to analyze patterns of dissemination of these technologies on the Internet.  相似文献

ABSTRACT

The aim of this paper is to examine the relationship between external cooperation and entrepreneurial orientation (EO). This relationship is explored in cluster environment, wherein entrepreneurial organizations compete and cooperate simultaneously to pursue opportunities. The following hypothesis is tested: External cooperation is positively correlated with entrepreneurial orientation. The hypothesis is tested with a correlation analysis on a sample of 77 small-sized enterprises operating in the Malopolska region in Poland, wherein several clusters are active. Additionally, the regression analysis is conducted to examine the associations between inter-organizational cooperation and EO dimensions. The findings confirm that external cooperation is positively correlated with EO. This observation is confronted with a pro-competitive approach that is a constitutional element of the entrepreneurship concept. Moreover, the findings show that the correlation between external cooperation and a firm’s performance is stronger than between some other EO dimensions and performance. Additionally, the findings show the important role of relationships between organizations and their clients. In the paper, several remarks for development of the theory are discussed, including the need for incorporating inter-organizational cooperation into a set of entrepreneurial traits and reflecting it in entrepreneurial orientation scales. The findings confirm the importance of that direction of theory development that focuses on inter-organizational collaboration in the context of entrepreneurship.  相似文献

Pesticide mismanagement potentially has high risks for farmers, households living in the community and the environment. In Papua New Guinea where farming is the primary occupation, there is evidence of dangerous herbicide application methods being used by coffee growers. Using original survey data for coffee smallholders from four provinces, we assess the factors driving farmers' use of personal protective equipment when preparing and applying herbicides, and farmers' disposal of agro‐chemical containers. We control for households' demographic variables and measure the impact of farmers' training in pest and disease management. We use the special regressor method to estimate binary choice models featuring an endogenous binary regressor (training). Our results show that human capital (education) and training are important drivers of farmers' pesticide‐handling practices, with marginal effects estimated at 10 and 22 per cent, respectively.  相似文献

Drawing on the contextual perspective, this study provides novel empirical evidence on how the organisational context (specifically, the firm's human resource strategy) has an effect on employee proactivity. We use matched data from managers and employees in 102 Spanish professional service firms to examine how high performance work systems contribute to enhance employee proactive behaviours through two motivational variables: role breadth self‐efficacy and flexible role orientation. Results of a multilevel study demonstrate that role breadth self‐efficacy mediates between HPWS and employee proactivity, but flexible role orientation does not mediate this relationship.  相似文献

This article investigates how securities analysts help investors understand the value of diversification. By studying the research that analysts produce about companies that have announced corporate spin‐offs, we gain unique insights into how analysts portray diversified firms to the investment community. We find that while analysts' research about these companies is associated with improved forecast accuracy, the value of their research about the spun‐off subsidiaries is more limited. For both diversified firms and their spun‐off subsidiaries, analysts' research is more valuable when information asymmetry between the management of these entities and investors is higher. These findings contribute to the corporate strategy literature by shedding light on the roots of the diversification discount and by showing how analysts' research enables investors to overcome asymmetric information.

This paper aims to provide empirical evidence for the connections between new trade theory and the spatial distribution of economic activities, considering the results obtained by the literature on New Economic Geography as a starting point. To do this, we apply Social Network Analysis specifically to the World Automotive Trade Network. We explore the structural features of the auto network for the years 1996 and 2009 using data on trade flows for 172 countries. Our findings suggest that the auto network has become denser, more extensive and more integrated over time, depicting a center-periphery structure in which regional clusters play a prominent role. In this configuration, strong agglomeration forces generated by companies’ desire for large and rich market access with minimum transportation costs are balanced by the search for new high-potential markets.  相似文献

This paper analyzes factors explaining supply and demand of local public transportation. Together with variables related to traditional economic factors and mobility, we consider variables reflecting institutional characteristics and geographical patterns. Being a political capital increases supply and demand of local public transportation, inequality is associated with higher supply, and contracting out reduces supply. Furthermore, our regional analysis allows us capturing the effect of geographical characteristics and different traditions of government intervention. In all, we provide first evidence on the role played by institutional and regional characteristics useful to achieve a better understanding of local public transportation supply and demand.  相似文献

Purpose: The objective of this study is to contribute to the sales management literature by analyzing whether self-monitoring dimensions (the ability to adjust the presentation of one’s self and the sensitivity to the expressive behaviors of others) play a moderating role in the use of impression management—supervisor liking—performance rating nomological network.

Methodology/approach: Empirical analysis is based on dyadic data from 122 industrial salespeople and their sales managers in 9 different industries. Structural equation modelling was used to analyze the psychometric proprieties of the measurement scales, and conditional process analysis was used to test the proposed hypotheses.

Research implications: The results obtained indicate that the use of supervisor-focused impression management tactics is an indirect antecedent of a salesperson’s performance rating through sales manager liking, but not the self-focused tactics. Results also show that a self-monitoring dimension i.e., the ability to adjust the presentation of one’s self, moderates the “impression management—supervisor liking—performance rating” chain. These results provide an increased understanding of the processes involved in sales managers—salespeople’s interactions.

Practical implications: The main implication for salespeople is that the use of impression management tactics to influence performance ratings only is effective when they use supervisor-focused tactics because attempts to influence via self-focused tactics will not have any effect. The most important implication for sales managers’ is that not all impression management tactics are successfully executed and that the identification of combinations of impression management tactics and the levels of salespeople’s self-monitoring can positively influence performance appraisals by generating evaluative biases. Given that evaluative biases can produce inequitable behaviors by sales managers in the task assignments and support provided to the salespeople, it is important that sales managers are aware of when they can occur (i.e., when salespeople with a moderate ability to adjust their self-presentation use supervisor-focused tactics).

Originality/value/contribution of the article: This article contributes to the existing knowledge by two important means. First, this study proposes a model and presents an empirical test of constructs that mediate (i.e., supervisor liking) and moderate (i.e., self-monitoring dimensions) the “use of impression management tactics—sales manager liking—performance appraisal” relation. This model responds to calls for studies that analyze how impression management tactics are related to performance appraisal and when the relation between the use of these tactics and performance rating occurs. Two, this study uses data from both salespeople and their sales managers, which minimizes any risk of common method variance bias.  相似文献

This paper explores whether a board's gender diversity influences the voluntary formation of its board subcommittees. Female board directorship may become a business strategy for firms if it affects the appointment of board subcommittees. We hypothesize that the voluntary creation of board subcommittees is affected by the presence of female directors on boards; the presence of independent, executive, and institutional female directors; and the proportion of shares held by female directors on boards. Board gender diversity has been measured as a proportion and with Blau's index. The results show that independent female directors are positively associated with the likelihood of voluntarily setting up all or some of the committees and a supervision and control committee. The presence of executive female directors negatively influences the probability of forming all or some of the committees, an executive committee and a supervision and control committee. The percentage of shares held by female directors has a positive effect on the voluntary creation of an executive committee. The findings also report that women directors and institutional female directors do not contribute to the voluntary creation of board subcommittees. Our evidence shows that female board directorship impacts the demand of internal control mechanisms such as board subcommittees, suggesting that firms should take it into account as a business strategy. The main implications derived from this research are relevant for Spanish policymakers and researchers because board gender diversity may play a significant role in the decision‐making processes of firms and may influence firms' outcomes.  相似文献
