This paper systematically reviews ex-post empirical studies assessing the effects of climate change mitigation policies on emissions. The findings suggest that most policies effectively reduce emissions, with a median effect of about -5% per year, though with substantial variation across studies.

This report provides data on export restrictions of industrial raw materials across countries and products. It reveals restrictions have increased significantly, which risks disrupting supply chains. Reduced restriction would lead to a better balance between security and development goals.

This report provides an analysis of global trade in counterfeit and pirated goods.

Artificial intelligence (AI) could help to address sluggish productivity growth in OECD countries. This report provides evidence for policymakers, business leaders and researchers to help understand the adoption of AI in enterprises and the policies needed to enable this. Achieving higher rates of AI adoption could raise labour productivity and have other desirable outcomes.
