An integrated tax-subsidy policy for carbon emission reduction

A carbon tax is often cited by economists as an effective instrument to mitigate greenhouse gas emissions, but there is little political interest in the United States. In light of this political unpopularity, we develop and examine a net-revenue constrained carbon tax and subsidy program. The optimal revenue constrained tax and subsidy schedule based on our utility maximization model taxes energy sources with high emissions to energy price ratio, and subsidizes sources with low emissions to energy price ratios. This approach may be more palatable than a traditional carbon tax because it can change the relative price of low and high emissions energy sources while providing a mechanism to limit net tax increases and energy price increases. We find that a constrained tax/subsidy program provides welfare gains relative to a no-tax scenario. Welfare gains are estimated to be 1% and 36% of the welfare gains from a Pigouvian tax for the motor fuels industry and electric power industry, respectively. In contrast, subsidies for low-emitting energy sources funded from general tax funds rather than from high-emission energy tax revenues lead to welfare decreases substantially below our proposed tax/subsidy policy approach.     

Place in Entrepreneurial Storytelling: A Study of Cultural Entrepreneurship in a Deprived Context

We extend the cultural entrepreneurship perspective by investigating how entrepreneurs in deprived contexts gain legitimacy by leveraging proprietary and public places in their entrepreneurial storytelling. Inspired by the sociology of place, we present a longitudinal study of ten new venture journeys over four years in Kasoa, Ghana. We identify three distinct ways places are used in entrepreneurial narratives: projective significance of place, connective significance of place, and authoritative significance of place. We show how impoverished entrepreneurs construct and communicate places in diverse ways, not only as locations, but also as material and symbolic resources that provide legitimacy for their venturing activities. Drawing from our findings, we generate a model of place-based cultural entrepreneurship and elaborate place as a central resource in cultural entrepreneurship and new venture creation in deprived contexts.     

Gender- and frame-specific audience effects in dictator games

We study dictator allocations using a 2×2$2\times 2$ experimental design that varies the level of anonymity and the choice set, allowing observation of audience effects in both give and take frames. Changes in the distribution of responses across treatment cells allow us to distinguish among alternative motives as elaborated in recent theory. We observe significant audience effects that vary by both frame and gender. The pattern of responses suggests that heterogeneous concerns for reputation and self-signaling across gender give rise to the contextual effects associated with the give and take frames that have previously been observed in the literature.     

中国的社会团体、公民社会和国家组合主义：有争议的领域

20世纪90年代中期以来学术界展开了一场争论：一派认为,应该用公民社会概念来研究中国团体;另一派通过调查研究认为,中国几乎所有团体的生活在本质上是国家组合主义。公民社会和组合主义都关注国家和社会之间的社团和其他机构。但不同的是：公民社会站在社会的角度,发展自治社团,维护“公共领域”的能力,以界定和制约国家权力;组合主义则相反,从国家的角度,为实现政府自己的目的,与选定的社团发展一种特殊的关系。在深入细致的实证研究基础上,学者们考察了中国不同类型社团的活动,得出了不同的结论,同时他们也超越了国家、社会和组合主义以及公民社会的框架,阐明了别的一系列重要的问题。

Understanding perpetual R&D races

This paper presents an experimental study of dynamic indefinite horizon R&D races with uncertainty and multiple prizes. The theoretical predictions are highly sensitive: small parameter changes determine if we should expect technological competition, and if so whether it is sustained, or if the market converges into one with entrenched leadership and lower aggregate R&D. The subjects’ strategies are far less sensitive. In most of the treatments, the R&D races tend to converge to entrenched leadership. We propose and apply a quantal response extension of Markov perfection that is qualitatively and largely quantitatively consistent with the experimental observations.     

No End to the Racial Wage Hierarchy in South Africa?

The South African apartheid system formally ended with the election of the African National Congress at the first all-race elections held in 1994. As a result, racist policies such as color barring, that particularly hindered the advancement of black workers throughout the apartheid period, are no longer legal. Yet the legacy of apartheid may endure as a result of both the persistence of racial differences in human capital attributes and the possible continuation of discriminatory practices within employment. In this paper the authors examine the evolution of the racial wage hierarchy in the early post-apartheid era against the background of the long-term decline in racial wage disparities observed over the last years of the apartheid regime. They find evidence that the position of black workers between 1995 and 1997 actually deteriorated relative to the overall geometric mean wage, while that of colored, Asian, and white workers improved.     

Public–private partnerships: Task interdependence and contractibility

We examine the proper scope of public–private partnerships in the context of a project consisting of two tasks, building and operation of a facility. We investigate the optimal arrangement regarding bundling versus unbundling and private ownership versus public ownership. Like Bennett and Iossa (2006), we assume that the innovative activity in the building stage has impacts on, among other things, the subsequent operational cost. We relax the nature of task interdependence and study different contractual frameworks. The general insight is that given limitations in contractibility, contrary to common sense, complementarity between tasks favors unbundling over bundling.     

Students’ knowledge sources and knowledge sharing in the design studio—an exploratory study

Architectural design is a knowledge-intensive activity; however, students frequently lack sufficient knowledge when they practice design. Collaborative learning can supplement the students’ insufficient expertise. Successful collaborative learning relies on knowledge sharing between students. This implies that the peers are a considerable design knowledge source for the students. However, students are involved in grade competition. Students may not be willing to share because knowledge is a critical resource for students’ performance. The web technology has been used to facilitate knowledge exchange among students; nevertheless, the convenience of technology may tempt free riding behavior and impede the development of a knowledge sharing culture. The purpose of this exploratory study is to probe whether the peers and a web forum are the students’ primary knowledge source by investigating students’ knowledge sources during the design process. The results demonstrated that (1) studio-mates were a primary design knowledge source for the students, (2) the ill-defined nature of design problems may be the main contributing factor encouraging knowledge sharing behavior, (3) the shared web forum was not a primary knowledge source for the students and did not have a significant influence on the knowledge sharing culture, and (4) we can estimate the knowledge sharing culture in a design studio through investigating students’ knowledge sources. Furthermore, several additional findings and implications are elaborated.
