This book presents frontier research on the use of computational methods to model complex interactions in economics and finance. Artificial Intelligence, Machine Learning and simulations offer effective means of analyzing and learning from large as well as new types of data. These computational tools have permeated various subfields of economics, finance, and also across different schools of economic thought. Through 16 chapters written by pioneers in economics, finance, Computer Science, psychology, complexity and statistics/econometrics, the book introduces their original research and presents the findings they have yielded.

Algorithmic thinking is gradually becoming an indispensable feature of Economics and Finance. Computational modes of thinking increasingly influence how we model individuals, organisations, market interactions and macroeconomic dynamics. Consider some topics that are traditionally of interest to economists and scholars of finance: decision-making by economic actors; mechanisms through which agents learn, adapt and thrive in uncertain, complex environments; the impact of economic decisions by individuals, firms and institutions on others in an interconnected system; emergence and diffusion of innovations; understanding volatility in financial markets; modelling aggregate, macroeconomic dynamics and associated pathologies (inflation, unemployment, inequality); and modes of exercising control through policy. All these issues are being studied using computational methods to varying degrees within the field.

Computational thinking in Economics and Finance can take diverse forms, ranging from straightforward applications of computational tools to analyse economic data, study properties of theoretical models (e.g., Computable General Equilibrium models), simulate large-scale Agent-Based Models (ABMs) and network models, perform numerical simulations, investigate game-theoretic scenarios; all the way to developing full-fledged algorithmic frameworks such as computable economics.

Computational methods and simulations are heavily relied upon to perform counterfactual thought experiments in ways that surpass the barriers posed by traditional mathematical and statistical tools. On the empirical front, Machine Learning (ML) and simulations have offered effective methods to analyse and learn from new types of data. These computational tools have permeated various sub-fields of Economics, Finance, and different schools of economic thought.

The question of what really constitutes AI continues to be debated. We prefer to take a broader, more plural view of AI to cover a broad umbrella of concepts, approaches and tools. These include: symbolic and sub-symbolic, connectionist approaches to AI, a range of Machine Learning methods such as supervised learning (e.g., artificial neural networks, nearest neighbour methods, kernel smoothening, probably approximately correct (PAC) learning, tree-based methods, classification algorithms, and support vector machines), unsupervised learning (e.g., self-organising maps, k-means, clustering), semi-supervised learning, ensemble learning (e.g., random forests), reinforcement learning, Deep Learning, natural language processing (NLP), evolutionary computation, ABMs, causal inference tools, ant algorithms and swarm intelligence.
