China's low-carbon city pilot policy (LCCPP) plays a crucial role in reducing carbon pollution and promoting green development. It stimulates enterprises' green innovation (GI), such as through the promotion of circular carbon technologies and energy-efficient practices. However, a negative...

The focus of climate economics has traditionally been on CO2 as a negative externality. For decades, this has led policymakers to strongly focus on carbon pricing as the preferred climate policy instrument. But addressing the climate crisis differs fundamentally from a pollution problem. It...

Climate policies do not operate in isolation but propagate through global production networks, affecting industries beyond national borders. This paper combines international input-output data with a granular instrumental variable approach to capture how foreign regulations transmit through...
