PurposeThe purpose of this paper is to investigate the influence of six determinants on taxpayers' intention to adopt e‐file systems. The proposed model integrates technology adoption factors from the unified theory of acceptance and use of technology (UTAUT) model with personal perceptions on trust, efficacy, and security into one parsimonious yet explanatory model of e‐file adoption.Design/methodology/approachA survey was administered to 304 US taxpayers to capture their perceptions of e‐filing. The survey was developed using existing scales in the literature. Responses were measured on a seven‐point Likert scale, ranging from 1 (strongly disagree) to 7 (strongly agree). The results were tested using multiple linear regression analysis.FindingsThe findings of this research show that theoretical constructs from the UTAUT model are well suited in explaining intentions to use multiple e‐government services. Specifically, the results indicate that three factors from the UTAUT model (performance expectancy, effort expectancy, and social influence) play a significant role in predicting taxpayers' e‐filing intentions. More importantly, the research findings indicate that personal factors (web‐specific self‐efficacy (WSSE) and perceived security control), along with UTAUT factors, have a significant impact on taxpayers' e‐file intentions. The proposed model explains 63.5 percent of the variance in taxpayers' e‐file intentions.Research limitations/implicationsThis study contributes to the literature by integrating determinants from the UTAUT model with personal perception factors to explain e‐file adoption. This merging of UTAUT with theories, such as social cognition, that emphasize human perception, is the direction that must be taken by researchers in an effort to understand taxpayers' intentions to adopt e‐file systems. While the proposed model explained 63.5 percent of the variation in e‐file use intention, there are limitations to this research. The participants in this research are not sufficiently diverse in culture, socio‐economic level, etc. and 89 percent of the research participants are Caucasian. In addition, the participants were recruited from limited geographical locations. The strength of the model should be validated using more diverse research participants that will increase the variation in the data collected.Originality/valueThe paper presents a parsimonious, yet integrated, model of e‐file diffusion. The integration of adoption factors with personal perceptions of trust, efficacy, and security represents a significant step forward in explaining e‐file adoption.

This study aims to examine the effect on stock returns of 28 terrorist and military events occurring between 1963 and 2012. The authors divide the sample and examine these attacks on the basis of industry, country targeted, location, terrorism versus militarism and predicted overall impact. The authors measure the effects of the events in our sample along several dimensions: in the aggregate; comparatively across industries; by each event's predicted level of impact; by the type of event (terrorist versus military); by the location of the attack (USA or outside the USA); and by whether the USA was, directly or by proxy, the primary target of the attack. Findings: Stock returns are significantly lower for those industries predicted to be most hurt than for other industries. Events that the authors predict to be of high impact to the market are followed by significantly lower returns than events we predict to be of low impact. Stocks perform significantly worse on the days of terrorist events than on the days of military events, but the opposite is true for the day after. Significantly lower returns follow events that occur inside the USA or where the USA was the primary target.

We examine the 'disappearing dividends' era documented by Fama and French (2001) with respect to the traditional theory of signalling, wherein the positive signal is one of high future cash flows and continued payments. We report several new findings. First, during the disappearing dividends era, dividends vanished not only because they were less frequently initiated-the oft-cited reason-but also because, once initiated, they were less likely to be sustained. Second, we find that although future performance does increase with dividend sustainability, performance is merely average for permanent payers and poor for temporary payers. Third, we find that the market responded favourably to initiations but did not distinguish ex-ante between short-run and longrun payers. Fourth, we find that despite the market's similar treatment of shorter-and longer-term payers, dividend sustainability was in fact predictable out of sample, using information strictly available to investors at the time of the announcement. Fifth, we find that performance is predictable through sustainability; the firms we predict to become permanent payers significantly outperform their counterparts in subsequent years. Overall, our findings run counter to the traditional signalling theory of dividends in terms of both overall firm performance and the market's reaction to initiations.

Noting increasing economic equality in three developed nations and using a theoretical economic model, Kuznets hypothesized that economic development was associated with initial increasing economic inequality followed by decreasing economic inequality. GDP and population data from 36 nations and regions, comprising the entire global economy and population, demonstrate a global Kuznets curve.
