Empirically testing ES success factors in business process reengineering

Previously proposed success factors for Expert Systems implementation are field tested in the context of business process reengineering (BPR) projects. Due to its nature mimicking human expert behavior, ES technology applications in BPR provide a unique opportunity to study major organization changes within a relatively short time. Using Pearson correlations and multivariate regression analysis, eight ES implementation success factors proposed in the literature were empirically tested in this study in terms of their importance to the BPR benefits derived from the application. Sixty-two ES applications within E.I. Dupont de Nemours and Company dealing with business process changes significant enough to be called BPR were used. Despite the relatively small sample size, six of the eight success factors were corroborated: user satisfaction with the ES, the importance and difficulty of the business problem addressed, user attitudes toward ES technology and the particular ES project, the degree of user involvement in the ES implementation process, and the ES developer(s) skills.     

Insider trading and firm-specific return volatility

Roll (J Financ 43:541–566, 1988) argues that firm-specific stock return volatility may result either from informed trading or from noise trading that is unrelated to information. In this paper we provide evidence that insider purchases are inversely related to the idiosyncratic volatility of stocks. We also find that stock idiosyncratic volatilities are generally inversely related to future 6- and 12-month returns. Our results are primarily driven by the timing of insider sales rather than insider purchases. The results are consistent with an information-based explanation of firm-specific return volatility.     

Narrative Transportation and Paratextual Features of Social Media in Viral Advertising

This study establishes that the experience of narrative transportation has a positive influence on viral advertising. The relative strength of this relationship, however, depends on several boundary conditions associated with the paratextual features of social networking service (SNS) environments. Specifically, it is stronger if the senders and intended receivers have personal ties. Moreover, the influence of narrative transportation is negatively moderated by advertising disclosure that elicits persuasion knowledge. Finally, the negative effect of persuasion knowledge is reduced if the ad appears with a higher number of “likes,” which increases social proof for viral ads. Implications regarding viral advertising and social media behaviors are discussed.     

Attracting Comments: Digital Engagement Metrics on Facebook and Financial Performance

Many companies are now using social media such as Facebook for advertising and marketing purposes. To understand how using social media affects a company's business performance from a digital engagement perspective, this study examines how user comments on company Facebook posts influence company revenue. S&P 500 companies' revenue information in a five-year time span (from 2010 to 2015) is collected, and this information is matched to more than 24 million user comments directed at these companies' Facebook posts. The hypotheses are tested using static (fixed effects [FE] and random effects [RE]) as well as dynamic (generalized method of moments [GMM]) panel data analyses in econometric methods. The estimation results indicate that digital engagement volume, defined as the total number of Facebook comments a company received, has a significant and positive effect on revenue. In addition, digital engagement valence, defined as the average tone of Facebook comments directed toward a company, also has a significant and positive effect on revenue. Implications and directions for future research are discussed.     

The Korea-Vietnam trade and the bilateral exchange rate: Asymmetric evidence from commodity trade data

The contribution of the current article is to detect the asymmetric impact that exchange rate fluctuations have on Korea's trade with Vietnam. To this end, the nonlinear autoregressive distributed lag (NARDL) process is applied to export and import data disaggregated by 25 commodities. We uncover that the ups and downs of exchange rates have an asymmetric impact on some, though not all, types of Korea's commodities exported to and imported from Vietnam in both the long- and short-run.     

Tying in two-sided markets with heterogeneous advertising revenues and negative pricing

We offer a theory of anticompetitive tying in two-sided markets when below-cost or negative pricing is possible. With the coexistence of two consumer groups (one regarding tying and tied goods as complementary and the other as independent), a tying-good monopolist may face difficulties in extracting rent under separate sales and wish to use tying to directly capture the large advertising revenue created in the complementary segment. We uncover two distinct mechanisms by which tying raises monopoly profits but reduces social welfare. Our theory of tying can be applied to real-world antitrust law enforcement, such as the Google Android case.     

Auditors’ scepticism in response to audit committee oversight behaviour

We use two experiments and a survey to examine how audit committee (hereafter, AC) oversight behaviour, particularly AC sceptical attitude and proactive behaviour, affects auditor scepticism, and whether the influence is driven by the risk aspect of auditors’ assessment of AC oversight behaviour. We find that when ACs exercise insufficient scepticism, auditors (junior auditors, managers, and partners) perceive AC oversight as weak, and increase their scepticism. However, AC proactive behaviour does not significantly influence auditor scepticism. Our findings suggest auditors view weak AC oversight as a risk indicator and respond by exercising greater scepticism.     

Does venture capital investment enhance corporate innovation? Evidence from Korea

We examine whether venture capital (VC) investment enhances corporate innovation in Korea. Using a matched sample of 802 firms from 1998 to 2012, we find that after the first round of VC investment, VC-backed firms are more innovative than non-VC-backed firms. Our results suggest that the positive influence of VC investment largely comes from the ability of VC firms to reduce information asymmetry between investors and ventures: VC funds managed by independent venture capitalists significantly enhance corporate innovation, whereas those managed by governmental venture capitalists do not. Furthermore, this positive influence becomes more pronounced where there is greater information asymmetry. Finally, we show that funds with profit-based compensation structures are more likely to encourage corporate innovation than those with fee-based compensation structures.     

The impact of COVID-19 on consumer evaluation of authentic advertising messages

This study investigates the relationship between the COVID-19 threat and consumer evaluation of a product with authenticity appeals in advertisements. We propose that threatening situations like COVID-19 motivate consumers to lower their uncertainty and increase their preference for products with authentic advertising messages. Because individuals react differently to threatening environments according to their early-life experiences, commonly reflected in childhood socioeconomic status, we examined whether childhood socioeconomic status moderates the relationship between threat and consumer evaluation of authenticity in advertisements. First, secondary data from Google Trends provided empirical support for our predictions. In additional experimental studies, participants evaluated different target products in four studies that either manipulated (Studies 2 and 3) or measured (Studies 4 and 5) COVID-19 threat. Our results provide converging evidence that consumers positively evaluate products with authentic advertising messages under the COVID-19 threat. Consumers' motivation to lower their uncertainty underlies the effect of COVID-19 threat on their evaluation of authentic messages (Study 3). This attempt to reduce uncertainty is more likely to occur for consumers with relatively higher childhood socioeconomic status (Studies 4 and 5). These findings suggest that using authenticity appeals during a pandemic could effectively reduce consumers' perceived uncertainty and generate positive consumer evaluations.     

THE IMPACT OF LOCAL FISCAL AND MIGRATION POLICIES ON HUMAN CAPITAL ACCUMULATION AND INEQUALITY IN CHINA

We develop and estimate a spatial overlapping generations model with heterogeneous households to study the feasibility of a recently proposed reform of internal migration policies that offers the potential of decreasing inequality within China. We find that this policy change significantly increases the college attainment of migrant children born in rural areas and, therefore, promises to increase the number of high-skill workers. However, it requires significant tax increases to offset the reduction of the positive fiscal externalities provided by migrants.
