Optimal Environmental Policy Differentials in Open Economies under Emissions Constraints

Is there a case for preferential treatment of the exposed sector in an economy when compliance to an aggregate emissions constraint induced by an international environmental agreement is mandatory? This question is being debated in many countries in the context of the implementation of the Kyoto Protocol. We address the issue in a general equilibrium framework and theoretically cover several market structures, including perfect competition, the large country case and oligopoly. We identify the conditions under which preferential treatment of the exposed sector is not warranted from the point of view of maximizing social welfare. In addition, we demonstrate that in the case of oligopoly, instituting a more stringent environmental policy on the exposed sector might be profit-enhancing for this sector. This finding lends theoretical support to a specific interpretation of the Porter hypothesis.     

The effects of agglomeration externalities on urban green total-factor productivity in China

For China's urban industrial layout and green development, determining which types of agglomeration externalities are most advantageous to the rise of green total-factor productivity has both theoretical and practical relevance. This research experimentally studies the effects of three types of agglomeration externalities on urban green total-factor productivity using the data of 285 Chinese cities from 2003 to 2018. The findings demonstrate that urban green total-factor output is rising, albeit with certain differences during different time periods. Both the Jacobs externality and the Porter externality are favorable for increasing urban green total-factor production when all cities are evaluated together, although the latter has a stronger promoting influence. The effect of the Marshall-Arrow-Romer externality, on the other hand, is not significant. Furthermore, these effects also depend on the stage of economic development and population size.     

Corporate governance,environmental regulations,and technological change

This paper investigates the relationship between environmental regulations and innovation by focusing on the automobile industry in a cross-country setting. We provide empirical evidence that the presence of agency problems mitigates the negative effects of environmental regulations on overall R&D activity, which leads to full compensation when the degree of agency problems is sufficiently high. Guiding our empirical analysis, we provide a general model consistent with the structure of existing ownership data. Specifically, we model ownership structure as a combination of two extreme corporate governance types. On the one extreme there are profit maximizers, and on the other extreme there are managers who are only concerned with their private benefits. The model leads to a simple country level ownership indicator and shows that if an economy is dominated by firms with higher agency problems, then pollution tax might even increase overall R&D, while reducing pollution. According to our estimations, such an outcome is possible only for out-of-sample values of the ownership indicator, where the degree of agency problems is extremely high.     

The environmental Porter hypothesis: theory,evidence, and a model of timing of adoption

The Porter hypothesis postulates that the costs of compliance with environmental standards may be offset by adoption of innovations they trigger. We model this hypothesis using a game of timing of technology adoption. We will show that times of adoption will be earlier if the non-adoption tax is higher. The environmental tax will turn the preemption game with low profits into a game with credible precommitment generating higher profits (pro-Porter). If there is a precommitment game without environmental taxes, the introduction of a tax will lead to lower profits (anti-Porter). An evaluation of the empirical literature indicates that the Porter hypothesis will hold even for profit-maximizing firms under multiple market imperfections such as imperfect competition, X-inefficiency, and agency costs. These are more likely to be present in sectors with large firms. In many case studies that we have evaluated, though, we detected an element of explicit or implicit subsidies for environmentally friendly behaviour, which is in line with Pigovian policies.     

Can voluntary environmental regulation promote corporate technological innovation?

The impact of environmental regulation on technological innovation has been widely discussed in the academic circle. Based on the panel data of 403 Chinese manufacturing firms from 2010 to 2015, this paper explored the role of voluntary environmental regulation in technological innovation. The results showed the following: First, both voluntary environmental information disclosure and environmental management system certification had a positive effect on corporate innovation investment. Second, compared with the impact of environmental information disclosure, the impact of environmental management system certification on corporate innovation investment was more significant. Third, there was a significant positive interaction between environmental information disclosure and environmental management system certification. Finally, the effect of voluntary environmental regulation on corporate technological innovation in heavily polluting industries was stronger than that in lightly polluting industries.     

British overseas retailing, 1900–60: International firm characteristics,market selections and entry modes

We examine the historical developments of the environmental adaptation process at one Swedish metal smelting firm, contrasting the result with cases in Canada. The findings suggest that the Swedish system in excluding stakeholders, focusing on plant emissions and stipulating pollution reduction at economically feasible costs mitigated risk which resulted in long-term contracts in a cooperative framework in which engineers were given a high degree of discretion. This enabled an ‘expansion-for-emission-reduction’ strategy which is consistent with the so-called Porter and van der Linde hypothesis. Moreover, the findings suggest that environmental management systems should be considered in the Environmental Kuznets Curve (EKC) research.
