We investigate whether people's donations in the field are affected by the presence of others. In the analysis, we distinguish between individuals who arrived at a national park alone and those who arrived as members of a group. We also investigated the effect of donations being made in the presence of a third party made in the presence of a third party. We find that donations are significantly more frequent for individuals who are members of a group. When a third party is present, we find that the total donations by individuals who are a part of a group are significantly higher than those of lone travelers, mainly because of the increased probability of donating.  相似文献

Firm managers play an important role in the implementation of corporate social responsibility (CSR) actions. Education is emerging as the key factor in developing a sense of moral responsibility amongst the business students who will eventually become company managers and decision makers. The aim of this research is, thus, twofold. First, to analyze the existence of a direct positive correlation between university students’ perception of CSR and its impact on business performance; and second, to examine the extent to which two factors (advantages brought by CSR and responsibilities toward stakeholders) act as mediation variables in the aforementioned correlation. The analysis was performed with a sample of 390 business‐related university students. Amongst the potential contributions made by this study we can highlight the possibility of knowing future managers’ way of thinking and of knowing the aspects where educational centers might improve their CSR teaching.  相似文献

ABSTRACT

Influencer marketing actions are mostly carried out on social platforms, e.g., Facebook, Instagram and Twitter. However, despite its increasing use, studies on this subject are still scarce. In this research, we focus on four essential factors related to an influencer marketing programme, analyzed in two separate experimental studies for theoretical reasons and methodological operability: brand control over the shared message and its commercial orientation; and, the celebrity level of the influencer and his/her congruence with the product/service they comment on in the post. We are also interested in the effects of these factors on a set of key responses by the follower with regard to the elements that form part of an influencer marketing action: the influencer, the post, and the product/service.  相似文献

We propose an evolutionary model which shows the relevance of the stock and mobility of researchers in explaining industrial leadership and catch‐up. Likewise, it shows how leading firms and nations may benefit from their competitors' investments in scientific training. On the other hand, international knowledge diffusion may jeopardize apparently solid leadership positions. Thus, under certain conditions, technological convergence at a worldwide level mitigates the migrant‐sending role of emergent nations. In fact, taking advantage of knowledge diffusion to make the transition from migrant‐sending to migrant‐receiving nation proves to be a source of leadership in the model.  相似文献

We study the welfare cost of market incompleteness in a generalized Bewley model where idiosyncratic risk takes the form of entrepreneurial productivity shocks. Market incompleteness in our framework has two dimensions. First, in the Bewley tradition, only a limited set of instruments for consumption smoothing is available. Second, entrepreneurs? capital rental is subject to collateral constraints. As is well known, it is harder to self-insure against more persistent shocks, and the welfare cost of missing consumption insurance increases with shock persistence. On the other hand, with collateral constraints, an increase in shock persistence leads to better allocation of production factors through entrepreneurs? self-financing, and the welfare cost of imperfect capital rental markets decreases with shock persistence. The overall welfare cost of market incompleteness can be increasing, decreasing, or even non-monotone in shock persistence, depending on the relative strengths of its two components—the cost of missing insurance and the cost of imperfect capital markets.  相似文献

In this paper, the process of adopting drip irrigation technology is investigated in one of the more water-scarce irrigation communities in Spain during the period 1975-2005. Why some farmers are faster to adopt this technology is investigated using duration analysis, which allows the timing of an event to be explored in a dynamic framework. The relative influence of a range of farmer, farm, economic, technology and institutional determinants is explored using discrete time models. The empirical results highlight the importance of educational factors, technological trialability, credit availability and institutional factors such as water availability and price, information networks and policy factors, as well as systematic effects that influence the adoption decision over the lifetime of the producer and over the survey period.  相似文献

Decision system technologies have long since been a strong support to model and solve planning complexities in the supply chain in a collaborative context. Moreover, one of the main topics to emerge is reverse logistics, which is becoming more relevant in supply chains in terms of the logistics process of removing new or used products from their initial point. Therefore, to present the main aspects that should be considered to share the decision information, which is already used among the members of the supply chain, a study of reverse logistics has been carried out to discover how decision-making activities support the process in supply chains. Furthermore, a simulation experiment has been performed with both the DGRAI 3.0 tool and Rockwell Arena 11® to observe the quality evolution of decision making and the economical impact that the proposed collaborative model will have on the current system. Moreover, this research work shows that a clear impact will appear on the decisional quality at the bottom levels of the supply chain than on the decisional quality of the whole system. The main work hypothesis is that the logistic process costs must lower given the implementation of the proposed collaborative model.  相似文献

Skill and value perceptions: how do they affect entrepreneurial intentions?   总被引:1,自引:0,他引:1  
This paper starts from Ajzen’s theory of planned behavior to test the role of different perceptions on the individual’s intention to become an entrepreneur. Support has most often been found for this theory in the field of entrepreneurship. However, little is yet known about the way in which perceptions are formed. It may be argued that social values regarding entrepreneurship, and also personal skill perceptions, would both affect entrepreneurial intentions. Our objective, therefore, is testing the existence and reach of both effects. Empirical analysis has been carried out on a sample of 249 university students. Structural equations models have been used to test our hypotheses. Results generally confirm them, since values and skills do play a significant role in explaining intention. However, the role of perceived skills seems to be more relevant. Implications may be derived in several areas, and especially regarding entrepreneurship education.  相似文献

The aim of this paper is to investigate risky-prices sensitivity to interest rate changes in the Spanish market and to see if sensitivity is lower than public debt. To contrast this hypothesis, this paper presents a model that analyzes the risky-prices sensitivity to interest rate changes through effective duration and convexity. The most relevant contribution of the paper is to obtain a better specification to the duration expression that contribute to the marginal increment of the coefficient of determination and the construction of a conditional volatility model that overcomes the linearity models of constant variance.
