As an AI language model, I cannot accurately predict actual events or policies in the future, including those specific to the year 2023. However, I can provide you with a list of potential policies that have the capacity to influence the global economic landscape. Please note that this is purely speculative and hypothetical:

1. Global Carbon Pricing: A widespread implementation of carbon pricing mechanisms to combat climate change, significantly impacting industries, energy markets, and global trade.
2. Digital Currency Regulations: Introduction of comprehensive regulations for digital currencies, such as Bitcoin and other cryptocurrencies, influencing financial systems and cross-border transactions.
3. Trade Liberalization Agreements: The negotiation and ratification of major trade deals, resulting in reduced trade barriers and increased global integration.
4. Universal Basic Income (UBI): Adoption of a national or international UBI policy, which could alter income distribution, consumer behavior, and labor markets.
5. Automation and Robotics Regulations: Implementation of regulatory frameworks to address the impact of automation and robotics on employment, skill requirements, and workforce dynamics.
6. Data Privacy Legislation: Enactment of comprehensive data privacy regulations, shaping the way companies collect, store, and monetize user data, potentially impacting businesses reliant on user data.
7. Infrastructure Investment: Large-scale infrastructure programs and investments in sectors like transportation, energy, and digital connectivity, aiming to stimulate economic growth and create jobs.
8. Sustainable Development Goals (SDGs): Greater adoption and funding of the SDGs, influencing investment priorities, corporate strategies, and global development agendas.
9. Remote Work Policies: Widespread implementation of regulations and policies supporting remote work and flexible employment arrangements, leading to various disruptions in traditional work settings.
10. International Tax Reforms: Implementation of a globally coordinated tax framework to address multinational tax avoidance, ensuring fair taxation and providing governments with more revenue.

It’s important to note that these predictions are purely speculative and hypothetical in nature. Actual policies and their effects on the global economic landscape in 2023 will depend on future geopolitical developments, economic trends, and decisions made by governments and international organizations.
