Earnings conference calls and stock returns: The incremental informativeness of textual tone

Quarterly earnings conference calls are becoming a more pervasive tool for corporate disclosure. However, the extent to which the market embeds information contained in the tone (i.e. sentiment) of conference call wording is unknown. Using computer aided content analysis, we examine the incremental informativeness of quarterly earnings conference calls and the corresponding market reaction. We find that conference call linguistic tone is a significant predictor of abnormal returns and trading volume. Furthermore, conference call tone dominates earnings surprises over the 60 trading days following the call. The question and answer portion of the call has incremental explanatory power for the post-earnings-announcement drift and this significance is primarily concentrated in firms that do not pay dividends, illustrating differences in investor behavior based on the level of cash flow uncertainty. Additionally, we find that a context specific linguistic dictionary is more powerful than a more widely used general dictionary (Harvard IV-4 Psychosocial).     

Vertical integration to avoid contracting with potential competitors: Evidence from bankers' banks

We examine a vertical integration decision within the commercial banking industry. During the last quarter of the 20th century, some community banks reduced their traditional reliance on correspondent banks for upstream products and services by joining bankers' banks, a form of business cooperative. Research on vertical integration focuses primarily on firm-specific investment, market power, and government regulation. However, this case is difficult to explain in terms of these standard vertical integration motives. Our evidence suggests that bankers' banks are a response to technological change and deregulation that results in increased costs faced by community banks in dealing with correspondent banks as both suppliers and potential competitors. For instance, loan participations require sharing proprietary information about major loan customers, something a community bank would not want to provide to a potential competitor.

Option and non-use values and rail project appraisal

Option values and non-use values are well-known concepts in environmental economics, but so far there been few attempts to apply the concepts to the transportation field. This paper therefore firstly reviews empirical studies on transport option and non-use values, and secondly examines the inclusion of option and non-use values in five rail scheme appraisals in the UK. We find that whilst the evidence base is small, the importance of option and non-use values is large where user benefits are low and for projects involving the provision (or loss) of commuting opportunities (including station openings/closures).     

A Cross-cultural comparison of customer complaint behavior in restaurants in hotels

This study documented consumer complaint behavior in hotel restaurants in two diverse cosmopolitan cities, Hong Kong, SAR and Houston, USA. It was found that in the area of food and beverage attributes, the Hong Kong group rated tastiness, temperature and freshness less important to make a complaint about the Houston group. As for service, service efficiency, greetings, attentiveness and helpfulness were rated differently, with the Hong Kong group rated “greetings” higher than the Houston counterparts. Regarding atmospherics, the two groups were most alike, though the Hong Kong group would be more likely to complain about the noise level while the Houston group, temperature and décor of hotel restaurants.     

The long memory model of political support: some further results

This article extends the results of Byers et al. (1997 Byers, JD, Davidson, JEHD and Peel, DA. 1997. Modelling political popularity: an analysis of long range dependence in opinion poll series. Journal of the Royal Statistical Society, 160: 471–90. Series A [Google Scholar]) on long memory in support for the Conservative and Labour Parties in the UK using longer samples and additional poll series. It finds continuing support for the ARFIMA(0,?d,?0) model, though with somewhat smaller values of the long memory parameter. We find that the move to telephone polling in the mid-1990s had no apparent effect on the estimated value of d for either party. Finally, we find that we cannot reject the hypotheses that the parties share a common long memory parameter which we estimate at around 0.65.     

Marketing “Gamer Foods”: Qualitative Insights into Responsible Strategy Development

The purpose of this article is to explore the video-gaming experience as a novel consumption occasion for snack foods and to provide insights into responsible marketing strategy development. Consumers' desired food product attributes, their motivating conditions to snack while gaming, and the environment in which this takes place are explored qualitatively through 14 in-depth interviews and 10 separate points of field observation. The findings indicate certain unhealthy food products are valued during the occasion for their social hedonic appeal but also for the basic function of fuelling long marathons of concentration and competition. Results are used to inform strategic considerations which are presented using the traditional marketing mix framework of product, promotion, price, and place of distribution. Therein, management is cautioned toward the obesogenic elements of the consumption occasion and this is a critical consideration throughout. Management is strongly advised to develop and promote healthier snacks as part of facilitating an enabling environment for sustainable food choices.
