We investigate determinants of investment decisions in investment‐based (equity and bond) crowdfunding campaigns, using a novel investment‐, investor‐ and campaign‐level database, where equity refers to investments in entrepreneurial start‐ups and bonds to large real estate projects. We find that investors who have higher social interactions invest more. Social interactions are important in an equity crowdfunding context but do not affect participation in bond investments. This is consistent with the view that investors' social networks help reduce information asymmetry. Women invest less in the riskiest (equity) investments but more in safer ones (bonds). These findings are better explained by differences in risk aversion than differences in overconfidence between men and women. Overall, the findings contribute to the understanding of how investment‐based crowdfunding can be a viable source of entrepreneurial finance and how entrepreneurs' campaign decisions affect investor participation in this new form of entrepreneurial finance.  相似文献

What causes adolescents to develop consumer’ ethical beliefs? Prior research has largely focused on the negative influence of peers and negative patterns of parent–child interactions to explain risky and unethical consumer behaviors. We take a different perspective by focusing on the positive support of parents and peers in adolescent social development. An integrative model is developed that links parental and peer support with adolescents’ self-worth motives, their materialistic tendencies, and their consumer ethical beliefs. In a study of 984 adolescents, we demonstrate support for a sequential mediation model in which peer and parental support is positively related to adolescents’ self-esteem and feelings of power, which are each associated with decreased materialism as a means of compensating for low self-worth. This reduced materialism is, in turn, associated with more ethical consumer beliefs.  相似文献

Opinion leaders propel the diffusion of innovation and exert a significant influence on the marketplace. This influence is especially pronounced during adolescence, a period marked by increasing reliance on peers and the emergence of a tension between two countervailing needs: assimilation and individuation. A survey of 1142 adolescents reveals that these developmental needs affect adolescent opinion leadership in the critical clothing market. Adolescent opinion leadership relies on a balance between desires for assimilation (i.e., centrality within the peer network) and individuation (i.e., need for uniqueness); adolescents' susceptibility to peers' normative influence and gender moderate these relationships. Adolescents who occupy central positions within their peer network tend to be opinion leaders, though only if they are not susceptible to normative influence. Position within the peer network is a key for girls, whereas need for uniqueness is a key for boys. These differences implicate different approaches for managers targeting adolescent males and females.  相似文献

As recently stakeholders complain about the use of conflict minerals in consumer products that are often invisible to them in final products, firms across industries implement conflict mineral management practices. Conflict minerals are those, whose systemic exploitation and trade contribute to human right violations in the country of extraction and surrounding areas. Particularly, supply chain managers in the Western world are challenged taking reasonable steps to identify and prevent risks associated with these resources due to the globally dispersed nature of supply chains and the opacity of the origin of commodities. Supply chain due diligence (SCDD) represents a holistic concept to proactively manage supply chains reducing the likelihood of the use of conflict minerals effectively. Based on an exploratory study with 27 semi-structured interviews within five European industries, we provide insights into patterns of implementation, key motivational factors, barriers and enablers, and impacts of SCDD in mineral supply chains. Our results contribute to both theory and practice as we provide first insights to SCDD practices and make recommendations for an industry-wide implementation of SCDD. Altogether, this study provides the basis for future theory testing research in the context of SCDD and conflict mineral management.  相似文献

Marketing research on adolescents’ ethical predispositions (EP) and risky behaviors (RB) has focused primarily on individual difference variables. The present study, in contrast, examines the social network positions that an adolescent occupies within a group. A survey of 984 adolescents demonstrates that EP and RB stem from a balance between assimilation (i.e., centralities within the peer network) and individuation (i.e., need for uniqueness). In particular, we show that adolescents with close first-degree relationships within a specific peer group (measured by high degree centrality) and/or high need for uniqueness have lower EP and engage in more RB, while adolescents that are more central to the entire network (measured by high closeness centrality) have higher EP. The theoretic and practical implications of these findings are discussed.  相似文献

The main objective of this paper is to show that the MultiNomial Logit (MNL) framework can be used for deriving simple acreage share models. More specifically we show that MNL acreage choice models can be defined as parts of consistent multicrop models. When coupled with suitably designed crop production models, e.g. a specific parameterization of the standard quadratic yield function, the parameters of these multicrop models are easily interpreted and estimated. Although MNL acreage choice models are usually derived by aggregating crop choices defined at the plot level, we show that these models can also be derived by considering a profit maximisation problem at the farm level. This provides a simple theoretical background for the Standard MNL acreage share model, as well as for simple extensions of these models: the Nested MNL acreage share models. An empirical application on French farm-level data over the period 1996–2007 investigates the empirical performances of the multicrop econometric models based on the proposed MNL framework for modelling acreage choices.  相似文献

We analyze the role of farm stock management on price volatility under liquidity constraints and heterogeneous price expectations. In commodity markets, speculative behaviors by stockholders tend to reduce price volatility, but this is not the case in certain agricultural markets, where speculation by farmers regarding decisions to sell or store grain is subject to liquidity constraints and heterogeneous price expectations. Like stockholders, most farmers sell grain if they expect a price drop in the near future, but unlike stockholders, they are not necessarily able to purchase grain if they expect a price increase in the next period. Heterogeneous price expectations can also lead to suboptimal storage decisions, further increasing price volatility. For these reasons, the storage management behavior of farmers often fails to mitigate price drops in the way that speculation by stockholders does. We merge historical data on maize prices and household storage collected in Burkina Faso in order to build a dynamic panel over the 2005–2012 period. We show that carryover from one season to the next is associated with unexpected price drops during the preceding lean season and that carryover is associated with more frequent unexpected price drops following the subsequent post‐harvest season.  相似文献

Agriculture is unique among economic sectors in the nature of impacts from climate change. The production activity that transforms inputs into agricultural outputs involves direct use of weather inputs (temperature, solar radiation available to the plant, and precipitation). Previous studies of the impacts of climate change on agriculture have reported substantial differences in outcomes such as prices, production, and trade arising from differences in model inputs and model specification. This article presents climate change results and underlying determinants from a model comparison exercise with 10 of the leading global economic models that include significant representation of agriculture. By harmonizing key drivers that include climate change effects, differences in model outcomes were reduced. The particular choice of climate change drivers for this comparison activity results in large and negative productivity effects. All models respond with higher prices. Producer behavior differs by model with some emphasizing area response and others yield response. Demand response is least important. The differences reflect both differences in model specification and perspectives on the future. The results from this study highlight the need to more fully compare the deep model parameters, to generate a call for a combination of econometric and validation studies to narrow the degree of uncertainty and variability in these parameters and to move to Monte Carlo type simulations to better map the contours of economic uncertainty.  相似文献

The implementation mechanisms of voluntary food safety systems   总被引:1,自引:0,他引:1  
The recent food scares have been the motivation for voluntary programmes on food safety being promoted by public authorities and voluntarily implemented by food operators. In this article, we take into account the nature of the contamination risk to investigate the complementarities between private and public mechanisms for those voluntary systems to be implemented by a firm. We show two main results. First, when the firm directly markets its products to consumers a strong mandatory threat is a sufficient condition to implement voluntary systems whatever the risk of contamination. In contrast, when the mandatory threat is weak voluntary systems should be more implemented in industries where the risk of food contamination is low (pesticide residue) than in industries where the risk of contamination is high (pathogenic contamination). Second, when the risk of food contamination is low and the firm is embedded in a supply chain where the retailer can impose its own safety system, a well-designed penalty contract will induce a voluntary implementation whatever the mandatory threat.  相似文献
