Conspiracy Beliefs

Research suggests that conspiracy beliefs are adopted because they promise to reduce anxiety, uncertainty, and threat. However, little research has investigated whether conspiracy beliefs actually fulfill these promises. We conducted two longitudinal studies ( NStudy 1 = 405, NStudy 2 = 1,012) to examine how conspiracy beliefs result from, and in turn influence, anxiety, uncertainty aversion, and existential threat. Random intercept cross-lagged panel analyses indicate that people who were, on average, more anxious, uncertainty averse, and existentially threatened held stronger conspiracy beliefs. Increases in conspiracy beliefs were either unrelated to changes in anxiety, uncertainty aversion, and existential threat (Study 2), or even predicted increases in these variables (Study 1). In both studies, increases in conspiracy beliefs predicted subsequent increases in conspiracy beliefs, suggesting a self-reinforcing circle. We conclude that conspiracy beliefs likely do not have beneficial consequences, but may even reinforce the negative experience of anxiety, uncertainty aversion, and existential threat.

The One

This paper deals with the margins of entrepreneurship at which small business owners are working almost on their own with no or very few employees, and where some work for low returns and run firms that lack stability and/or prosperous dynamics. However, even the area of ‘entrepreneurship at the margins’ is a wide field, embracing not only the broad margins of entrepreneurship but also the fluid borders between entrepreneurship and the informal sector on the one side and the labour market system on the other. New firms – even those that are ultimately very successful – may be more or less created in an experimental market and product testing phase, in which business founders are still employed or registered as unemployed before becoming self-employed. In such cases, the practical starting-point of an entrepreneurial existence is part of a fluent continuum of different activities closely connected to the entrepreneur's sphere of dependent work as an employee or job-seeking during a period of unemployment. The paper addresses this area of entrepreneurship within an integrated framework, which combines entrepreneurship analysis with labour market research and studies on social stratification and social mobility. It contributes to the debate on entrepreneurship at the margins by combining selected empirical information on the case of Germany with conceptual ideas of a labour market perspective. The integrated approach highlights some key issues and raises further questions about the field of entrepreneurship.

The Impact

Purpose The purpose of this paper is to study the disposition effect that is exhibited by the investors through the review of research articles in the area of behavioral finance. When the investors are hesitant to realize the losses and quick to realize the gains, this phenomenon is known as the disposition effect. This paper explains various theories, which have been evolved over the years that has explained the phenomenon of disposition effect. It includes the behavior of individual investors, institutional investors and mutual fund managers. Design/methodology/approach The authors have used the existing literatures from the various authors, who have studied the disposition effect in either real market or the experimental market. This paper includes literature over a period of 40 years, that is, Dyl, 1977, in the form of tax loss selling, to the most recent paper, Surya et al. (2017). Some authors have used the PGR-PLR ratio for calculating the disposition effect in their study. However, some authors have used t-test, ANNOVA, Correlation coefficient, Standard deviation, Regression, etc., as a tool to find the presence of disposition effect. Findings The effect of disposition can be changed for different types of individual investors, institutional investors and mutual funds. The individual investors are largely prone to the disposition effect and the demographic variables like age, gender, experience, investor sophistication also impact the occurrence of the disposition effect. On the other side, the institutional investors and mutual funds managers may or may not be affected by the disposition effect. Practical implications The skilled understanding of the disposition effect will help the investors, financial institutions and policy-makers to reduce the adverse effect of this bias in the stock market. This paper contributes a detailed explanation of disposition effect and its impacts on the investors. The study of disposition effect has been found to be insufficient in the context of Indian capital market. Social implications The investors and society at large can gains insights about causes and influences of disposition effect which will be helpful to create sound investment decisions. Originality/value This paper has complied the 11 causes for the occurrence of disposition effect that are found by the different authors. The paper also highlights the impact of the disposition effect in the decision-making of various investors.
