Presidential administrations and the day-of-the-week effect in stock returns

This study examines the presence of a day-of-the-week effect over different presidential administrations. The results indicate that the day-of-the-week effect prevails during the Democratic and Republican administrations. However, the pattern of the day-of-the-week effect differs between the two presidential administrations. Specifically, the negative returns on Monday are more pronounced during the Republican than during the Democratic administrations. Therefore, explanations for the day-of-the-week effect should take into account the changing pattern of the day-of-the-week effect across presidential administrations.     

Trends and cycles in economic time series: A Bayesian approach

Trends and cyclical components in economic time series are modeled in a Bayesian framework. This enables prior notions about the duration of cycles to be used, while the generalized class of stochastic cycles employed allows the possibility of relatively smooth cycles being extracted. The posterior distributions of such underlying cycles can be very informative for policy makers, particularly with regard to the size and direction of the output gap and potential turning points. From the technical point of view a contribution is made in investigating the most appropriate prior distributions for the parameters in the cyclical components and in developing Markov chain Monte Carlo methods for both univariate and multivariate models. Applications to US macroeconomic series are presented.     

The effects of executives' experiences and perceptions on their assessment of potential technological alliances

Researchers have only begun to provide explanations of how top executives' experiences and perceptions influence organizational decisions. Drawing from a broad theoretical base, this study tests the contention that top executives' personal experiences (age, educational background, and work experience), their perceptions of their firms' attitudes toward technology and risk, and their perceptions regarding their firms' past success with collaborative technological development influence their cognitive assessments of potential technological alliances. Results from the study suggest that top executives with a technical education place more weight on the opportunities provided by the alliance than those with other types of education. Moreover, executives from firms that are perceived to emphasize technology and to have had success with technological alliances in the past tend to focus more on the opportunities provided by the alliance and less on the riskiness of the venture. © 1998 John Wiley & Sons, Ltd     

Examining the influence of servant and entrepreneurial leadership on the work outcomes of employees in social enterprises

Abstract

The present study examines the relative influence of two distinct leadership styles, servant leadership and entrepreneurial leadership, on the organizational commitment and innovative behavior of employees working in social enterprises. Analyzing data from 169 employees and 42 social entrepreneurs, we found that, although servant leadership was positively related to followers’ organizational commitment, the relationship between entrepreneurial leadership and organizational commitment was insignificant. In contrast, whilst we found evidence that entrepreneurial leadership was positively related to followers’ innovative behavior, the relationship between servant leadership and employees’ innovative behavior was insignificant. Our research contributes to the underdeveloped literature on leadership in social enterprises by exploring the relative effectiveness of different leadership styles (namely an entrepreneurial leadership style and a servant leadership style) in promoting follower work attitudes and behaviors in social enterprises. In addition, our research demonstrates the importance of leadership over and above followers’ individual differences such as pro-social motivation and creative self-efficacy.     

Health Literacy,Health Numeracy,and Trust in Doctor: Effects on Key Patient Health Outcomes

This research examines the roles of health literacy, health numeracy, and trust in doctor on: (1) patient anxiety when consulting a doctor; (2) frequency of physician consultations; and (3) patient subjective well-being (SWB). Our sample consisted of 4,040 adults representative of the United States in terms of age, income, and education, but equally split among White/Caucasian (50%) and Black/African American (50%) respondents. We found that functional and communicative health literacy and trust in doctor have linear and curvilinear relationships with anxiety when consulting a doctor. Health numeracy had no effect. Anxiety when consulting a doctor was associated with a lower number of physician consultations and lower SWB. We observed direct linear effects of health literacy, health numeracy, and trust in doctor on frequency of physician consultations and SWB, as well as some curvilinear effects. We found a negative relationship between health numeracy and SWB. We discuss implications of these findings for health and public policy.     

Interconnections Between Eurozone and US Booms and Busts Using a Bayesian Panel Markov‐Switching VAR Model

The proposed panel Markov‐switching VAR model accommodates changes in low and high data frequencies and incorporates endogenous time‐varying transition matrices of country‐specific Markov chains, allowing for interconnections. An efficient multi‐move sampling algorithm draws time‐varying Markov‐switching chains. Using industrial production growth and credit spread data, several important data features are obtained. Three regimes appear, with slow growth becoming persistent in the eurozone. Turning point analysis indicates the USA leading the eurozone cycle. Amplification effects influence recession probabilities for Eurozone countries. A credit shock results in temporary negative industrial production growth in Germany, Spain and the USA. Core and peripheral countries exist in the eurozone. Copyright © 2016 John Wiley & Sons, Ltd.     

Centre‐based and expedition‐based (wilderness) adventure experiential learning regarding personal effectiveness: an explorative enquiry

The purpose of this study is to compare a centre‐based adventure programme (CBAP) with an expedition‐based wilderness programme (EBWP) with regard to personal effectiveness. In comparing these two programmes, this study made use of a crossover research design with data collection according to DE Vos. Participants were 28 third‐year students (14 men and 14 women), aged 20 to 23 ( x = 21.6 ± 0.7) from the Northwest University (Potchefstroom Campus) in South Africa. Both interviews and questionnaires (n = 28) were used to gather comprehensive data. Results indicated medium‐(d = 0.5) to‐practically significant (d ≥ 0.8) changes in most of the ROPELOC (Review of Personal Effectiveness and Locus of Control) variables. Each programme offered unique benefits. The EBWP resulted mainly in improvements in terms of the personal aspects of the ROPELOC, whereas the CBAP mainly delivered in terms of its social aspects. Even though both programmes seem to be beneficial for the facilitation of personal effectiveness, each programme should be selected according to the envisaged outcomes and intervention criteria. For the improvement of personal effectiveness, the EBWP seems to be of relatively more value – mainly on account of the impact of the wilderness environment. This translates into unique experiences of solitude, privacy and freedom of choice, spiritual upliftment, and restoration.     

A synthesis of pure demand analysis

Abstract

§ 1. Summary and comments. Since Augustin Cournot, the pure theory of economic equilibrium consists in a separate analysis of demand and supply, the chief problem being- to prove the existence of a price constellation for which demand equals supply. In the theory of demand involved, it is a fundamental principle that demand is uniquely determined by income and prices. This principle is the central theme of the present paper.
