Re-examining the role of attitude in information system acceptance: a model from the satisfaction–dissatisfaction perspective

This study attempts to re-examine the role of attitude in voluntary information system (IS) acceptance and usage, which has often been discounted in the previous technology acceptance research. We extend the unidimensional view of attitude into a bidimensional one, because of the simultaneous existence of both positive and negative evaluation towards IS in technology acceptance behaviour. In doing so, attitude construct is divided into two components: satisfaction as the positive attitudinal component and dissatisfaction as the negative attitudinal component. We argue that satisfaction and dissatisfaction will interactively affect technology usage intention. Besides, we explore the predictors of satisfaction and dissatisfaction based on the disconfirmation theory. Empirical results from a longitudinal study on bulletin board system (BBS) usage confirm the interaction effect of satisfaction and dissatisfaction on usage intention. Moreover, perceived task-related value has a significant effect on satisfaction, while perceived personal value has a significant effect on dissatisfaction. We also discuss the theoretical and managerial implications of our findings.     

Does investor sentiment impact the returns and volatility of Islamic equities?

In this paper, we estimate generalized autoregressive conditional heteroskedasticity (GARCH) and vector autoregressive (VAR) models to examine whether investor sentiment impacts the returns and volatility of various U.S. Dow Jones Islamic equity indices. The results from GARCH estimations show that changes in investor sentiment are positively correlated with the returns of the Shari’ah-compliant market portfolio. In addition, we find similar results for the three Shari’ah-compliant firm-size portfolios (i.e., large-, medium-, and small-cap). However, this relationship is stronger for harder to arbitrage Shari’ah-compliant stocks; that is, investor sentiment has a greater influence on small-cap equities. Additionally, estimations from the vector autoregressive model confirm the aforementioned results. In terms of volatility, GARCH estimations suggest that bullish shifts in investor sentiment in the current period are accompanied by lower conditional volatility in the ensuing period. In general, our findings suggest that as noise traders create more risk the market seems to reward them with higher expected returns.     

The role of the public sector in the provision of housing supply in Turkey, 1950–2009

This study examines the changing role of the public sector in Turkey with regard to housing provision since 1950, and particularly since 2000, and seeks to clarify how public intervention has affected housing provision and urban development dynamics in major cities. Three periods may be identified, with central government acting as a regulator in a first period characterized by a ‘housing boom’. During the second period, from 1980 to 2000, a new mass housing law spurred construction activity, although the main beneficiaries of the housing fund tended to be the middle classes. After 2000, contrary to emerging trends in both Northern and Southern European countries, the public sector in Turkey became actively involved in housing provision. During this process, new housing estates were created on greenfield sites on the outskirts of cities, instead of efforts being made to rehabilitate, restore or renew existing housing stock in the cities. Meanwhile, the concept of ‘urban regeneration’ has been opportunistically incorporated into the planning agenda of the public sector, and — under the pretext of regenerating squatter housing areas — existing residents have been moved out, while channels for community participation have been bypassed.     

The risk–return relation in the corporate loan market

This paper analyzes the hypothesis that returns play a risk-compensating role in the market for corporate revolving lines of credit. Specifically, we test whether borrower risk and the expected return on these debt instruments are positively related. Our main findings support this prediction, in contrast to the only previous work that examined this problem two decades ago. Nevertheless, we find evidence of mispricing regarding the risk of deteriorating firms using their facilities more intensively and during the subprime crisis.     

The Russia–Ukraine conflict and investor psychology in financial markets

This study examines the effect of the Russia–Ukraine conflict on global financial markets and the resulting changes in investor psychology. We have analysed weekly data from January 2021 to March 2023, including indicators such as gross national income, Bitcoin historical price, Standard and Poor 500 index, US consumer price index, US dollar index, and investor psychology index, using a variety of econometric techniques. Our findings reveal a positive and significant correlation between investor psychology and market returns. These results highlight the importance of monitoring investor psychology during times of conflict as it can greatly impact investment decisions in financial markets, providing valuable insights for investors and policymakers.     

The intranet's role in newcomer socialization in the hotel industry in Taiwan – technology acceptance model analysis

This study examined a research model for explaining the relationships of intranet adoption and newcomers' organizational socialization in the hotel industry. Data were gathered for a structural equation model (SEM) analysis, from 298 individual participants, who had only worked in a hotel for 6 months to 1 year. The research results demonstrated the mediation role of the perceived usefulness (PU) and perceived ease of use of the intranet. The SEM results also revealed that usage of the intranet did increase the extent of an employee's socialization into the organization. Moreover, PU has direct and indirect effects on socialization. Tests on gender and age differences were conducted. The invariance analysis of the theory model showed that both males and females demonstrated the same patterns in performing technology acceptance factors and socialization, whereas different age groups demonstrated significantly different paths. The direct effect of PU was not significant for the newcomers aged over 35.     

Decomposing the effects of crowd-wisdom aggregators: The bias–information–noise (BIN) model

Aggregating predictions from multiple judges often yields more accurate predictions than relying on a single judge, which is known as the wisdom-of-the-crowd effect. However, a wide range of aggregation methods are available, which range from one-size-fits-all techniques, such as simple averaging, prediction markets, and Bayesian aggregators, to customized (supervised) techniques that require past performance data, such as weighted averaging. In this study, we applied a wide range of aggregation methods to subjective probability estimates from geopolitical forecasting tournaments. We used the bias–information–noise (BIN) model to disentangle three mechanisms that allow aggregators to improve the accuracy of predictions: reducing bias and noise, and extracting valid information across forecasters. Simple averaging operates almost entirely by reducing noise, whereas more complex techniques such as prediction markets and Bayesian aggregators exploit all three pathways to allow better signal extraction as well as greater noise and bias reduction. Finally, we explored the utility of a BIN approach for the modular construction of aggregators.     

Factors affecting delinquency of household credit in the U.S.: Does consumer sentiment play a role?

In this study, we provide both theoretical and empirical evidence on the determinants of household loan delinquency for home ownership, credit card and auto loans for the U.S. states in a panel framework over a period from 2003 through 2017. In particular, we examine the impact of consumer sentiments on loan delinquency rates. We show that improved current consumer sentiment significantly induce lower mortgage, credit card and automobile loan defaults in the American states subdivided into four different regions. We also find that the higher overall and expected consumer sentiment raise loan delinquencies. Implicit in this finding is the apparently excessive and inappropriate expansion of loans in the U.S. economy in the face of consumers’ optimism, which in turn, provides an intuitive understanding of the circumstances that could precede a depression or outbreak of anomalies in the financial sector. Our general findings further exhibit significant positive effect of unemployment rate and mostly adverse effect of per capita income on mortgage and automobile loan delinquency rates. The results provide some compelling evidence with regard to the effect of consumer confidence on household credit delinquency rates across various states in the U.S. and are robust to alternative measures of income and mortgage rates.     

The relation between the equity risk premium and the bond maturity premium in the UK: 1900–2006

Using a rich data set for the UK for over a century, we find that the relation between the equity risk premium and the government bond maturity premium is nonlinear and subject to stochastic regime switching. We identify a regime in which both premia are jointly characterized by low volatility and another regime in which both premia are characterized by high volatility. The occurrence of the high volatility regime chronologically coincides with major changes in the pound exchange rate. The low volatility regime has a higher probability of turning up over two consecutive years than the high volatility regime, but it is not perceived by investors to be an absorbing regime. The lagged maturity premium is a strong predictor of the equity risk premium only in the regime of low volatility. In addition, the lagged equity premium is a predictor of the maturity premium also in the low volatility regime. This result on regime-dependent bidirectional predictability is robust to alternative definitions of the equity premium, and to the inclusion of real interest rate and real growth effects.

Economic policy uncertainty,investor sentiment and financial stability—an empirical study based on the time varying parameter-vector autoregression model

This paper applies the time varying parameter-vector autoregression model to explore the dynamic relationship between economic policy uncertainty, investor sentiment and financial stability in China in different periods and at different time points. The empirical results show that economic policy uncertainty has an obvious negative impact on investor sentiment before 2012 and financial stability in the short term, and the influence of economic policy uncertainty on investor sentiment is greater than that of economic policy uncertainty on financial stability. These influences were more significant during the period of the global financial crisis in 2008. Moreover, investor sentiment had a positive and gradually increasing effect on financial stability, while after 2010, the positive impact gradually weakened. Furthermore, economic policy uncertainty is negatively affected by financial stability, and the effect of financial stability on investor sentiment is positive. In terms of mediating effects, economic policy uncertainty has an indirect impact on financial stability through investor sentiment and vice versa. This paper provides a new solution to economic problems explored in behavioral finance research. Additionally, Chinese government agencies can achieve the goal of preventing financial crises and maintaining financial stability by monitoring investor sentiment and implementing targeted economic policies.

     

The role of villages in households’ poverty exit: evidence from a multilevel model for rural Vietnam

Vietnam experienced a dramatic drop in overall poverty during the 90s. However, the poverty reduction showed substantial variation across households, villages and regions. Using a multilevel model on panel data from the rural sample of the Vietnam Living Standard Measurement Survey we demonstrate the important role of villages in household poverty exit dynamics. We also show how an analysis of village-level random effects predictions can help targeting of policies to reduce poverty.     

French multinational companies’ strategies and co-ordination mechanisms: the role of human resource management in Europe and Nigeria

The everchanging European context may well lead to the evolution of MNCs’ strategies in Europe and to the evolution of the control mechanisms within their subsidiaries. The author analyses the issue from the angle of human resources management, considered as an informal control tool that is widely recognized by both scholars and managers. This research therefore aims at analysing whether or not and how HRM systems embody a possible integration process in the European economic space. The methodology is based on a case study from a French multinational company belonging to the automobile industry while the investigation, a comparative analysis of the headquarters-subsidiaries relationships in England, Spain and Nigeria, points out the specificity of the European context regarding corporate strategy orientations, subsidiary roles and personnel transfer policies. The major conclusions from such an analysis suggest a framework that gives prominence to the differentiation of the management process between Europe and Nigeria.

These results confirm previous literature on co-ordination mechanisms in complex business organizations.     

The effect of unethical behavior on trust in a buyer–supplier relationship: The mediating role of psychological contract violation

Research on trust in buyer–supplier relationships has tended to focus on the performance outcomes of a trusting relationship, as well as the processes that serve to build trust. Largely absent from the buyer–supplier literature is an in-depth examination of activities that break down trust, and the resulting effect on supplier trust in the buyer. The authors propose and test a model that evaluates psychological contract violations between a buyer and a supplier as a mediating variable of the effect of unethical activities on trust within a partnership. Survey data was collected from 110 tier one suppliers of major corporations in the state of Ohio. Our results show how a supplier's perception of a violation of the psychological contract either partially mediates or fully mediates the relationship between the buyers unethical activity and the suppliers trust in that buyer. We discuss how suppliers may demonstrate bounded ethicality when they overlook perceived unethical behaviors by the buyer.     

Protective faith? The role of religiosity in the stressor-strain relationship in helping professions

Abstract

Working conditions in western economies keep fueling work stress and psychological ill-health among employees. Job resources as well as personal resources play important roles in alleviating the adverse outcomes. In this article, we analyze religiosity as a rather neglected personal resource and its role in the stressor–strain relationship. Five dimensions of religiosity (intellect, ideology, public practice, private practice, and experience) are tested for their buffering effect on the relationship between work stress, measured as effort-reward imbalance, and psychological strain as well as for their direct relationship with psychological strain. The sample consists of 792 helping professionals and a comparison group of 172 non-helping professionals. The results show that public practice is negatively related to psychological strain for helping professionals while none of the religiosity dimensions has an effect among non-helping professionals. A buffering effect of religiosity on the relationship between work stress and psychological strain is not observed. The results contribute to the literature on the model of effort-reward imbalance as well as religiosity in the workplace and the role of personal resources in the stress process.     

The role of political tactics on the organizational context–career success relationship

Drawing from the norm of reciprocity, signal theory, and psychological contracts, we argue that the use of different types of political tactics, based on their social desirability, can be reciprocal behavioral reactions to contextual cues (i.e. perceptions of organizational support and politics) that can predict career success. Using a sample of 117 middle managers, our findings suggest that the use of sanctioned political tactics partially mediates the relationship between perceptions of organizational support and career success, while non-sanctioned political tactics suppress the relationship between perceptions of organizational politics and career success.     

Regulating Audit in Europe: The Case of the Implementation of the EU Eighth Directive in Denmark 1984–2006

This paper examines the extent of financial information disclosure on the Internet by the largest companies in the UK in 1998. Companies were surveyed to establish whether they had a website and if so whether financial information was available. We also investigated whether that information was in summary form or whether the full annual report was available. This study finds a statistically significant positive relationship between the size of a company and the use and extent of disclosure on the Internet. There was no significant association between industry type and disclosure.     

The role of lending-relationship banks in the underwriting of seasoned equity offerings: Conflict of interest or certification?

Sections 20 and 32 of the 1933 Glass–Steagall Act address a potential conflict of interest by banning commercial banks from the market for corporate securities underwriting. This restriction was officially rescinded in 1999 by the Gramm–Leach–Bliley Financial Modernization Act. In turn, this development has piqued the interest of scholars and renewed the debate on the role that commercial banks play, as well as the consequences of this role in equity offerings, which may either result in conflict of interest or certification. In this study, we comprehensively examine whether conflict of interest or certification more accurately characterizes the underwriting of seasoned equity offerings (SEOs) by lending-relationship banks. Overall, the results suggest that the presence of lending-relationship banks lowers the gross spreads and underpricing of SEOs. Furthermore, our evidence shows that SEOs led by lending-relationship banks exhibit better long-run performance than other SEOs, which supports the certification hypothesis.     

Suppes–Sen maximality of cyclical consumption: The neoclassical growth model

In this paper we demonstrate the existence of cyclical consumption that are maximal according to the Suppes–Sen grading principle for the Aggregative Growth Model. The paper demonstrates the optimality of cyclical consumption paths in the absence of discounting for the smooth neoclassical growth model. The process of this verification allows us to develop the theory of weakly maximal paths for a non-concave and discontinuous utility function extending previous results from Optimal Growth Theory.     

On Kullback–Leibler information of order statistics in terms of the relative risk

The representation of the entropy in terms of the hazard function and its extensions have been studied by many authors including Teitler et al. (IEEE Trans Reliab 35:391–395, 1986). In this paper, we consider a representation of the Kullback–Leibler information of the first \(r\) order statistics in terms of the relative risk (Park and Shin in Statistics, 2012), the ratio of hazard functions, and extend it to the progressively Type II censored data. Then we study the change in Kullback–Leibler information of the first \(r\) order statistics according to \(r\) and discuss its relation with Fisher information in order statistics.     

Recasting the “middle man:” the role of charities in the age of disintermediation

The number of people donating to charities is declining at a time when technology is enabling a proliferation of new ways of offering support—from crowdfunding to hacking commercial platforms like AirBnB for novel purposes. There is a risk that charities could lose their traditional position as a trusted intermediary between individuals who want to help and people who need their support. This paper offers some suggestions as to why disintermediated giving may, in some situations, offer a more attractive donor experience than traditional charitable giving and suggests some possible areas for further study.
