We use topic modeling to study research articles in environmental and resource economics journals in the period 2000–2019. Topic modeling based on machine learning allows us to identify and track latent topics in the literature over time and across journals, and further to study the role of different journals in different topics and the changing emphasis on topics in different journals. The most prevalent topics in environmental and resource economics research in this period are growth and sustainable development and theory and methodology. Topics on climate change and energy economics have emerged with the strongest upward trends. When we look at our results across journals, we see that journals have different topical profiles and that many topics mainly appear in one or a few selected journals. Further investigation reveal latent semantic structures across research themes that only the insider would be aware.

This research presents a theoretical model and examines it empirically to associate attachment orientations with various types of entrepreneurs. The results show clear evidence that attachment orientations not only predict an adult’s tendency to become an entrepreneur but also the type of entrepreneur he will become. Specifically, the results show that attachment anxiety is the dimension that is the most responsible for the variability of becoming an entrepreneur, while anxiety and avoidant dimensions predict his characteristics and attitudes as an entrepreneur. This paper makes five important contributions to the research of both attachment theory and entrepreneurship. First, it adds to the theoretical understanding of the psychology of entrepreneurs. Second, the attachment theory enables us to extend our understanding beyond the predictions of personality traits regarding entrepreneurial intentions in order to further predict the type of entrepreneur he will turn out to be. Third, it stresses the role of early childhood events regarding the prediction of future entrepreneurial orientation. Fourth, it uses a unique data set of real young entrepreneurs in a single industry homogenous design in Israel, which is known worldwide as a startup nation. Fifth, it focuses on the opportunity validation stage (rather than the opportunity identification of the resource allocation stages), which is often neglected in entrepreneur personality research.  相似文献

Exaggerated portion sizes are generally pictured on the front of product packaging in order to stimulate food craving and encourage consumer purchasing decisions. However, one problem with such images is that they can set inappropriate norms as far as food consumption is concerned and hence result in people serving themselves more than they otherwise might. The research reported here builds on the fact that depicting a food portion in a smaller (vs. larger) container (i.e., plate or bowl) creates the illusion of a larger (vs. smaller) portion, although the actual quantity of food remains the same (this is known as the Delboeuf illusion). Here, we demonstrate in two experiments that by presenting food in a smaller container (thus giving rise to the illusion of a relatively larger portion), participants have higher purchase intentions (study 1) and perceive the food as being more appetizing (study 2) but, crucially, decrease the size of the portion that they serve themselves (studies 1 and 2). Overall, by giving the impression of a larger portion on product packaging, the Delboeuf illusion could potentially be used to nudge consumers to find food more desirable, while at the same time leading them to reduce their serving, thus potentially benefitting both consumers and the food industry.  相似文献

Drawing upon the theory of virtue ethics, this study builds a decision tree predictive model to explore the anticipated impact of good traits (i.e., virtuous and personality traits) on socially responsible consumption. Using R statistical software, we generate a classification tree and cross-validate the model on two independent datasets. The results indicate that the virtuous traits of self-efficacy, courage, and self-control, as well as the personality traits of openness and conscientiousness, predict socially responsible purchase and disposal behavior. Remarkably, the largest segment of socially responsible consumers in the study (41 %) scored high in self-efficacy and openness. This result suggests that marketers should focus on these good traits when creating advertisements to encourage sustainable consumption. Our study contributes to enhancing knowledge about the social and psychological aspects of the sustainability movement and provides a new analytical approach to predicting socially responsible consumption.  相似文献

Supermarket retailers typically operate with relatively low margins, suggesting a highly competitive retail environment. However, despite the fact that consumers purchase an entire shopping basket at a time from supermarkets, this evidence is largely based on models of retail competition with single-category purchases. In this paper, we develop and test an empirical model of retail price competition that explicitly accounts for the effect of demand complementarity among items in consumer shopping baskets. Relative to the case where consumers purchase products with independent demands, we demonstrate that equilibrium prices are higher for all items when retailers take demand-complementarity into account. Our findings indicate that non-price strategies intended to encourage complementarity, such as co-merchandising, strategic shelf-positioning, or featuring complementary goods tend to soften price competition, and lead to higher equilibrium prices.  相似文献

This paper investigates how the timing of social support, both emotional and instrumental support, affects entrepreneurial persistence of nascent entrepreneurs. Drawing on social support theory, we hypothesize that the effectiveness of support depends on when, during the venture development process (number of gestation activities completed), it is provided. We also propose that the impact of social support depends on when during the entrepreneur’s life stage (age) that support is made available. Testing our hypotheses using a longitudinal dataset of nascent entrepreneurs, we find that emotional support is most relevant earlier on during venture development, while instrumental support is most relevant for entrepreneurs who begin their businesses in earlier life stages.  相似文献

One common justification for the pursuit of profit by business firms within a market economy is that profit is not an end in itself but a means to more efficiently produce and allocate resources. Profit, in short, is a mechanism that serves the market’s purpose of producing Pareto superior outcomes for society. This discussion examines whether such a justification, if correct, requires business managers to remain attentive to how their firm’s operation impacts the market’s purpose. In particular, it is argued that the value of efficiency, despite views to the contrary, cannot be fully separated from the planning and intentions of business managers as long as those managers direct their firms in an ethically responsible fashion. This position is inspired by, and serves as a supportive clarification of Joseph Heath’s so-called “market failures approach” to business ethics.  相似文献

Drawing on Denison and Mishra (1995)’s framework of organizational culture, this study examines why and when organizational culture is related to knowledge workers’ affective commitment. Data were collected from 640 employees working in three high-technology companies in China. The findings indicate that the relationship between organizational culture and affective commitment is mediated by perceived psychological contract fulfilment. In addition, organizational tenure moderates the relationship between two external dimensions (i.e. adaptability and mission) of organizational culture and perceived psychological contract fulfilment. This study extends the current theoretical framework of organizational culture by demonstrating the underlying mechanism and the boundary condition of the relationship between organizational culture and affective commitment. The findings also provide practical implications for international managers to design appropriate human resource management policies and practices in China.  相似文献
