    Emissions Trading Schemes and Directed Technological Change: Evidence from China
    (2020-11) Tian, Ruijie; Department of Economics, University of Gothenburg
    This paper examines the impact of carbon emissions trading schemes (ETS) on technical change proxied by the number of green patents in the context of the pilot ETS in China. I find a small increase of 0.16 patents per firm and year. A 10 percent increase in carbon prices increases green patents by 2 percent. The strongest effects are for the two regions in the upper range of carbon prices and for more productive firms. However, there are contrasting patterns at the extensive and intensive margins of green innovation: the pilot ETS reduces entry into green innovative activities but increases levels of innovating for firms that were innovative before they were regulated by ETS, especially for the more productive firms. This indicates that an important policy challenge is to encourage the firms covered by ETS to start innovation in green technologies; this applies particularly to the larger and more productive firms.

    Impacts of Climate Policy and Natural Disasters: Evidence from China
    (2021-08-17) Tian, Ruijie
    The last decade has seen heightened interest in carbon pricing to reduce greenhouse gas emissions responsible for anthropogenic climate change. Over the past decade, China–responsible for over a quarter of global carbon emissions–has aimed to reduce its emissions through an ambitious Emissions Trading Scheme (ETS) which charges certain firms for the greenhouse gases they emit. This dissertation evaluates the behaviour of firms regulated by the pilot ETS and also studies the economic consequences of adverse shocks in the form of natural disasters. The first two chapters analyse the impact of the pilot ETS on firm behaviour in China. Chapter one assesses the impacts of the pilot ETS on technical change. The second chapter evaluates how the pilot ETS affected emissions reduction and whether the initial allowance allocation had no impact on emissions in subsequent years–a necessary condition for a cap-and-trade market to be efficient. The final chapter uses Chinese firm-level data to detect the international propagation of adverse shocks triggered by the US hurricane season in 2005.
