Does informed trading occur in the options market? Some revealing clues

This paper analyses the relationship between proxy variables for informed trading in the options market and a set of exogenous news variables. The aim was to test directly for the presence or absence of informed trading in the options market and for the possible impact of this trading on underlying asset prices. Our findings reveal that potential informed trading in options markets is channelled basically through out‐of‐the‐money options, except for volatility trading which mainly involves at‐the‐money options because of their liquidity. In both cases, we have found evidence in favour of investors’ strategic fragmentation of transactions into intermediate size trades (stealth trading). Finally, it is shown that lack of consensus among agents also generates increased trading, particularly in out‐of‐the‐money and at‐the‐money options.     

Relationship between the Mean and the Constant in a Box–Jenkins Time Series Model

In some publications the mean is identified with the constant of a Box–Jenkins time series model. In this paper the relation between both terms is demonstrated. Furthermore, by means of an example, the errors which may be made if one does not use each term adequately are shown.     

Risk and Return Around Bond Rating Changes: New Evidence From the Spanish Stock Market

Abstract:  This study analyzes the effect of corporate bond rating changes on stock prices in the Spanish stock market. We explore their effects on excess of returns and systematic risk. Rating changes by Moody's, Standard and Poor's and FitchIBCA are analyzed. On an efficient market, these changes will only have some effect if they contain some new information or if they are associated to a redistribution of wealth between shareholders and bondholders. We use an extension of the event study dummy approach. Our results support the redistribution of wealth hypothesis in the abnormal returns behavior. We also find that changes in both directions cause a rebalancing effect in the total risk of the firm, with significant reductions on their systematic component.     

Does Family and Lone Founder Involvement Lead to Similar Indebtedness?

This study evaluates whether the presence of a lone founder and family involvement impact private firms’ leverage differently from a methodological view. Using a sample of 4,102 private firms in Spain and taking under consideration a panel data structure from 2006 to 2013, we find that lone founder and family involvement matter in capital structure decisions and size shapes the forementioned influence. Our findings show that lone founder involvement always implies higher debt than the rest of firms and suggest that firms with genuine family involvement are significantly low debt companies.     

Store attributes leading customer satisfaction with unplanned purchases

Understanding which specific factors of retail stores’ offering affect unplanned buyers’ satisfaction may be of great interest to store managers as they could set ad hoc strategies to target these consumers and establish long-term, profitable relationships with them. Satisfied unplanned buyers could indeed return to the store where they purchased their unplanned item(s) and/or positively talk about it with other customers. Nevertheless, we still know very little about such factors. To close this gap, this research gathered survey data on consumers’ store satisfaction and perceptions of store attributes in Spain during two time periods: in 2008, when the crisis was barely noticed by Spanish consumers, and five years later, when consumers were experiencing this economic situation. The results obtained evidence how grocery retailers can respond to customers’ awareness of the crisis by providing some managerial recommendations for bolstering satisfaction in consumer segments with diverse levels of unplanned buying behavior.     

The tourism SMEs in the global value chains: the case of Andalusia

This paper examines the implications of the globalization of value chains for the role of small and medium-sized enterprises (SMEs) in the tourism industry. To begin with, the configuration of the global tourism value chain is analysed. Next, the participation of Andalusian SMEs in the global tourism value chains is investigated. A number of case studies have been developed in two relevant sectors, hotels and travel agencies, giving priority to the main tourist typologies existing in Andalusia: sun and sand, business and congress, cultural and rural. As a result, a SWOT analysis has been produced. Finally, from the key findings some policy recommendations supporting the role of tourism SMEs in global value chain are made.

Do independent directors protect shareholder value?

The present global financial crisis has revived the notion that competitive markets may lead some directors and executives to behave in opportunistic ways considered unethical and even illegal, through the pursuit of self‐interest. This article proposes and tests an integrated model that offers new insights into the relationship between board structure, independence and firm value. By incorporating the proportion of independent directors on the board as a moderating factor in this relationship, this study contributes to a better understanding of the entrenchment and convergence‐of‐interests hypotheses. Using empirical data obtained from 114 Spanish listed companies in a context of economic crisis, from 2007 to 2010, we conclude that having a board with a greater proportion of independent directors reduces the negative association existing between firm value and a large board size and significant board share ownership.     

TQM and performance: Is the relationship so obvious?

This study explores the relationship between total quality management (TQM) and firm performance taking TQM as an internally consistent system of practices. The study tests the link between the two variables using the universal approach, analyzes whether the most competitive firms are those adopting TQM, and tests for an isomorphic effect on other firms. The study uses a sample of Spanish firms that have received TQM prizes at the national or regional level between 1997 and 2003 and a control sample for comparison. The findings indicate that in the absence of any evidence to confirm the universal hypothesis, TQM pioneers experience performance gains, because of the early implementation of the system; however, late adopters do not experience similar results. Firms using a TQM system are not necessarily better than their counterparts are, before putting the system into action. The study uses panel data that takes into account the unobservable heterogeneity between individuals and the dynamics of firms' financial variables.     

Legal dispossession and civil war in Colombia

How are institutions that regulate property rights related to the massive coercive dispossession of land that took place during the Colombian conflict? How did the workings of these institutions change during the conflict? We answer these questions through an analysis of a unique data set of rulings on land restitution issued between 2012 and 2015. The paper argues that the exclusionary nature of the institutions that regulate the access and assignment of property rights preceded the onset and escalation of the Colombian conflict, but shows how and why once the conflict began, the set of techniques used to promote coercive dispossession through those institutions could be significantly broadened and escalated. By doing so, it intends to advance the knowledge of how institutions are transformed, in this case in a deeply anti‐egalitarian and violent sense, during war.
