This study examines the environmental policy mix of tradable emission permits and emission taxes in a duopoly model with a consumer‐friendly firm. We analyse the interplay of the two policies and the welfare consequences in the presence of excess burden of taxation. We show that an emission tax can be redundant when both the excess burden of taxation and the degree of consumer friendliness are insignificant. However, when the excess burden of taxation is significant, tradable permits policy with tax treatment should be applied to enhance welfare in the presence of a consumer‐friendly firm. Finally, under the tax revenue‐neutral case where the excess burden of taxation does not matter, the environmental policy mix is also efficient if the degree of consumer friendliness is sufficiently high.  相似文献

ABSTRACT

Flow theory is used in this article [Csikszentmihalyi, M. (1990). The domain of creativity ] to determine whether gamified resources, named Accountingame and Marketingame, possess certain characteristics which, in the form of educational games, increase the performance of Portuguese undergraduate students attending Accounting (N?=?816) and Marketing (N?=?195) curricular units for the first time. A structural equation model was used to look into the direct effects of the characteristics of the game, such as Concentration, Clarity, Feedback, Challenge, Autonomy, Social Interaction, and Perceived Learning, on students’ learning Flow. Results clearly show that, with the exception of Feedback, all the other dimensions were Flow predictors. Overall, by introducing games into the curriculum, students’ motivation and interest increased and demonstrates that games can be an effective way for students to learn.  相似文献

An elicitation format prevalently applied in discrete choice experiments (DCE) is to offer each respondent a sequence of choice tasks containing more than two choice options. However, empirical evidence indicates that repeated choice tasks influence choice outcomes through order effects. The study reported in this article employs a split sample approach based on field surveys to expand the research on effects of repeated‐binary DCE elicitation formats. A single‐binary elicitation format is used as the baseline. Our results indicate that choice outcomes may vary across the single‐binary and repeated‐binary elicitation formats. The choice between the two elicitation formats may imply a trade‐off between decreased choice precision in the single‐binary and order effects that may be explained by strategic misrepresentation of preferences, cost uncertainty effects and reference effects in the repeated‐binary elicitation format.  相似文献

Public-sector services feature some very specific characteristics that frequently prove to be obstacles to innovation. This article therefore discusses how co-creation, within a Service-Dominant (S-D) logic, may contribute to innovation in these organisations and overcome the challenges posed by scarce resources and a multiplicity of clients and objectives and maintain citizen consensus around these activities. This discussion is backed up by examples drawn from the United Nations awards made annually for the best public-sector practices and innovations.  相似文献

This article investigates if investing in local hedge funds improves the risk-return relationship of Brazilian pension funds. Investment in hedge funds by pension funds is growing elsewhere, with an increasing utilization of a multiplicity of hedge funds specialized in specific strategies or niches. We analyzed the performance of a typical pension fund allocation in Brazil as well as alternate allocations that included hedge funds. We used robust estimates of the covariance matrix to mitigate the errors in variables that are problematic in the inputs of the optimization. The results show that hedge funds improve the risk-return relationship of the typical pension fund allocation, contribute to a higher accumulated return at the end of a one-year period, and reduce portfolio rebalancing. Investments in hedge funds ease reaching the typical 6% annual return target with less risk exposure.  相似文献

This study aims to investigate whether foreign direct investment (FDI) growth improved the Brazilian foreign trade in the long run and whether there is a predictable relationship between a firm's FDI strategy and a firm's foreign trade. We applied moderated multiple regressions and generalized linear models to test the effects of FDI on both export and import equations of 11 Brazilian industries from 1996 to 2009. Our data sources include the Ministry of Development, Industry and Foreign Trade Ministry, Central Bank of Brazil, and the Applied Research Institute. Results showed that FDI is correlated with increased exports in the short run, but not in the long run. In the long run, the positive relationship between FDI and exports will only occur for export-oriented industries in which resource-seeking strategies are preponderant. We found a positive relationship between imports and FDI in the short run, particularly in import-oriented industries. A negative relationship between FDI and imports was found in the long run.  相似文献

This paper is part of a research project which highlights the legal and ethical problems of mobile services aimed at children in Spain. The aim of the paper is to offer practical advice on self-regulation in the mobile telephone sector in Spain and to suggest measures that companies could adopt to protect children more effectively. A multivariate statistical analysis was carried out on the results of confidential surveys sent to companies, government agencies and child protection associations in order to establish the key issues to be taken into consideration when drawing up a collective agreement. Children have access to a wide range of services via their mobile phones. We question the suitability of these services and whether the age of the children should be verified before access to these services is allowed. Company policy should include the drawing up of codes of conduct along the lines of the agreement signed by the leading European mobile phone operators.  相似文献

Urban research has long related informality to a lack of state capacity or a failure of institutions. This assumption not only fails to account for the heterogeneous institutional relations in which informality is embedded, but has also created a dividing line between states. Whereas some states are understood to manage urban development through functioning institutions, others, in this view, fail to regulate. To deconstruct such understandings, this article explores informal practices through a multi‐sited individualizing comparison between three case studies of water governance, parking regulation and dwelling regimes in Bafatá (Guinea‐Bissau), Tallinn (Estonia) and Berlin (Germany), respectively. Our approach to understanding informality starts from the negotiation and contestation of order between differently positioned actors in the continuous making of states. From this point of view, informality is inherent in the architecture of states––emerging through legal systems, embedded in negotiations between and within institutions, and based on conflicts between state regulations and prevailing norms. Tracing how order takes shape though negotiation, improvisation, co‐production and translation not only highlights how informality constitutes a modus operandi in the everyday workings of the state in all three cases, but also provides a way to talk across these cases, i.e. to bring them together in one frame of analysis and overcome their presumed incommensurability.  相似文献

ABSTRACT

Entrepreneurship is becoming an important source of employment for women in many countries. There are different circumstances and motives that contribute to the decision to start a business. In this study, we developed a model that can estimate the probability of individuals becoming nascent entrepreneurs by opportunity or necessity. The model considers individuals' sociodemographic characteristics and European economies' perceived characteristics as oriented towards efficiency or innovation. Statistical logistic regression was used to test the model. The results show statistically significant differences between genders, European economies oriented either to efficiency or innovation, and entrepreneurs who are born out of opportunity or necessity.  相似文献
