Public Policy and Decision Science

This page is about the intersection of policy-making and machine learning For an overview of policy-making and decision science, please see the Wikipedia page on this topic.

When creating policies, decision-makers must often negotiate fundamental uncertainties in the underlying data and construct mathematical models to help them assess or trade off between different policy alternatives. ML can help alleviate some of this uncertainty by extracting information from satellite imagery, sensors, social media posts, policy documents, and other source and provide new techniques for working with models commonly used by decision-makers (e.g. integrated assessment models, multi-objective optimization, etc.) ML can also help retroactively, by analyzing the text of existing policies and by performing causal inference on historical data.

Generally speaking, carbon markets aim to reduce GHG emissions by setting limits on emissions and enabling the trading of emission units, which represent emission reductions. ML can help predict prices in carbon markets and analyze the main drivers of these prices to improve their efficiency. In terms of the design of market-based strategies, such as carbon tax or cap-and-trade programs, it is necessary to understand how effectively each strategy will reduce emissions, as well as how the underlying socio-technical system may be affected. ML can help assess the outcomes of market-based strategies to ensure they are effective and equitable.

Libraries and Tools
Given the importance of representing the impacts of decision-making and market-based strategies, interactive simulation tools and packages for multi-objective optimization are particularly useful in this application. Some of these are listed below:


 * Carbon market simulation tool: demystifies how to develop and implement a carbon portfolio management strategy, and demonstrates that results are driven by design.
 * Python packages for multi-objective optimization:
 * Evolutionary Multi-Objective Optimization (EMOO)
 * Platypus - Multi-objective Optimization in Python: Platypus is a framework for evolutionary computing in Python with a focus on multiobjective evolutionary algorithms (MOEAs), providing optimization algorithms and analysis tools for multiobjective optimization.
 * Matlab package for multi-objective optimization: Matlab package for multi-objective optimization, accompanied by tutorial videos and explanations.

Data
There are several sources of data at various global, regional, and national levels, all of which are useful for modeling the impact of policies, as well as markets
