We extend the identification results for nonparametric simultaneous equations models in Matzkin (2008) to situations where the observations on the vector of dependent variables might be limited, and where the number of exogenous unobservable variables is larger than the number of dependent variables. 相似文献
This paper presents a qualitative analysis about the determinants related to rescheduling travel mode decisions during the activity scheduling process. Notably, we were interested to study changes between intention and behavior. Data used came from an in-depth Computer Assisted Telephone Interview (CATI) follow up survey to habitual drivers carried out during the implementation of a panel survey. An interpretative qualitative method based on Analytic Induction was used to cope with the complex nature of rescheduling decisions and the characteristics of the data. The Theory of Planned Behavior has been used to gain a better understanding of the reasons associated with rescheduling travel mode decisions and to obtain a possible explanation of the phenomena studied. In our sample, 12 codes were identified as the main determinants of travel mode changing. Main reasons for rescheduling a travel mode are different considering gender, age, and the type of travel mode change. Main reasons for changing a nonprivate preplanned travel mode to a private travel mode are different considering the type of travel mode preplanned. New determinants of rescheduling decisions different from those associated with other activity scheduling decisions previously identified emerge when analyzing travel mode changes. A number of important sustainable transportation policies to reduce car use in urban areas are derived from the results of this study. 相似文献

An innovative way to support cultural institutions is through reward-based crowdfunding, an online funding mechanism for a specific project, which offers donors a reward for their donation. We explored employees' perceptions of crowdfunding and focused on the question: “How do employees of cultural institutions running a crowdfunding campaign perceive the use of crowdfunding to collect funds?” To answer this question, we focus on interpretive research using semi-structured interviews (n = 15) among Dutch cultural institutions' employees responsible for running the crowdfunding. We used earlier findings on psychological ownership to structure the interviews. Psychological ownership is the feeling that the project has become an employee's extension, and previous research linked it to success on the work floor. Our findings claim four lessons. First, crowdfunding is a full-time job and not an extra activity. Second, crowdfunding differs from traditional fundraising: it contains specific content-related tasks they do not perform as fundraisers. Third, crowdfunding asks for teamwork. While autonomy is valued, one employee should not be responsible for the campaign. Fourth, crowdfunding does not come naturally to all cultural institutions. This research provides a basis for further specification of crowdfunding and its implementation in the cultural sector. 相似文献
The present study examined how the multi-country green technology co-patenting network structure evolved from 1997 to 2016. For that purpose, we used Social Network Analysis tools, which allowed us to assess the network structure from a visual and quantitative perspective. The results indicate that the network expanded as the number of participating countries and ties increased. In all periods, the network grew significantly centralized around a small group of countries, in which the U.S., Great Britain, Germany, France, and Canada had paramount weight. Emerging countries like India and China also stood out due to their growth over time, as they eventually managed to gain central positions in the network. Other developing countries remained marginal, such as Brazil.
In this article, which is based on an empirical analysis of neoliberal restructuring in Leipzig, East Germany, I describe how the study of affective atmospheres adds to our understanding of urban restructuring, showing how collective moods affect (de)mobilization, contestation and the regulation of urban political economy to shed light on the relation between institutional, political and social processes. I demonstrate the relevance of affect for power relations, political interactions beyond rationality, and the rhythms and temporalities of urban restructuring, as exemplified by two prominent atmospheres that characterize Leipzig—post shrinkage depression (PSD) and anticipatory hope (AH). 相似文献
The Catalan case in south-western Europe offers us the opportunity to take a detailed look at the impact a lowering of the interest rate may have had on the poor of a specific area. It is vital to examine how property rights operated in specific contexts, given the close relationship between land and credit markets. Our working hypothesis is that, in some instances where property rights were redefined, as happened in eighteenth-century Catalonia, the reduction of the interest rate in secured loans benefitted the poorer social groups. The findings of this research, in line with those of some development economists, suggest that only an empirical and bottom-up perspective allows for a proper analysis of the eradication of poverty by placing it within the real picture of social change. 相似文献
A manufacturer relies on an exclusive subcontractor for production and competes horizontally against an integrated rival that produces in-house. The exclusive agent is privately informed about the marginal cost of production. When marginal costs are correlated across companies, information sharing benefits both companies due to reduced uncertainty, but it affects the contracting terms within the vertical hierarchy and creates horizontal externalities between companies. We show that the manufacturer who suffers from agency cost benefits more from sharing information than his rival performing in-house production only when costs are highly correlated, and in this case, information sharing may actually benefit consumers. 相似文献
