Environmental Policy and Directed Technical Change in a Global Economy: The Dynamic Impact of Unilateral Environmental Policies
نویسنده
چکیده
This paper builds a two-country (North, South), two-sector (polluting, nonpolluting) trade model with directed technical change, examining whether unilateral environmental policies can ensure sustainable growth. The polluting good is produced with a clean and a dirty input. A temporary Northern policy combining clean research subsidies and a trade tax can ensure sustainable growth but Northern carbon taxes alone cannot. Trade and directed technical change accelerate environmental degradation either under laissez-faire, or if the North implements carbon taxes, yet both help reduce environmental degradation under the appropriate unilateral policy. I characterize the optimal unilateral policy analytically and numerically using calibrated simulations. JEL Classi cation: F18, F42, F43, O32, O33, O41, Q54, Q55

The Dynamic Impact of Unilateral Environmental Policies
This paper builds a two-country, two-sector (polluting, nonpolluting) trade model with directed technical change, examining whether unilateral environmental policies can ensure sustainable growth. The polluting good generates more or less emissions depending on its relative use of a clean and a dirty input. I show that a unilateral policy combining clean research subsidies and a trade tax can e...
متن کاملEnvironmental Policy and Directed Technical Change in a Global Economy: Is There a Case for Carbon Tariffs?
In an open economy, can unilateral environmental policies undertaken by a group of committed countries ensure sustainable growth? This paper addresses this question in a dynamic model with directed technical change. There are two countries and two tradeable goods. One of the two goods (the polluting good) is produced with a clean input and a dirty input, which causes a global externality. Innov...
متن کاملUpgrading Wastewater Treatment Plants Based on Reuse Demand, Technical and Environmental Policies (A Case Study)
Reclamation and reuse programs are an indispensable part of integrated water resource management, particularly in arid and semi arid regions. Yet, the feasibility of sustainable application not only is relied on design, operation and maintenance of wastewater treatment plants, but also could be influenced by the economical and environmental aspects of reuse demands. This study is aimed to illus...
متن کاملCarbon and energy taxes in a small and open country
Malaysia, as a small and developing country, must reduce carbon emissions because the country is one of the top CO2-emitting countries in the ASEAN region. Therefore, the current study implements two environmental tax policies; carbon and energy taxes, in order to examine the impacts of these policies on the reduction of carbon emission in the whole of the economy by applying a compu...
متن کاملThe Impact of Macro-prudential policies on the Vulnerability of the Banking System: Dynamic Panel Model
In the aftermath of the global financial crisis (2007-2009), policymakers in the developing countries and emerging economies have generally relied on macroprudential policies to achieve financial stability. Since the banking systemchr('39')s vulnerability plays an essential role in financial instability, and the banking systemchr('39')s stability is exposed to vulnerability, we examine macropru...
