The OECD Business and Finance Outlook 2016 highlights the ongoing challenges in global business investment and productivity growth, particularly in a fragmented regulatory environment. It identifies factors inhibiting investment, such as high excess capacity and insufficient corporate restructuring, and emphasizes the necessity of targeted fiscal incentives for research and development to drive productivity. The document also discusses the impact of bribery and investment treaty fragmentation on corporate governance and the need for consistent enforcement of anti-corruption measures.
