Stefano Zambelli

Opis

Nonlinearity, Complexity and Randomness in Economics presents a variety of papers by leading economists, scientists, and philosophers who focus on different aspects of nonlinearity, complexity and randomness, and their implications for economics. A theme of the book is that economics should be based on algorithmic, computable mathematical foundations.

• Features an interdisciplinary collection of papers by economists, scientists, and philosophers
  
• Presents new approaches to macroeconomic modelling, agent-based modelling, financial markets, and emergent complexity
  
• Reveals how economics today must be based on algorithmic, computable mathematical foundations

Blurb

The "great crash of 2008" and its associated banking crisis have revealed the limitations of mainstream economics. While exposing the increasing irrelevance of the field, they have forced a number of economists to re–examine their discipline. The financial meltdown also showed how traditional linear or linearised models with well–behaved additive stochastic disturbances, based on orthodox "microeconomic foundations", are not adequate to deal with the complexities of today′s world. Nonlinearity, Complexity and Randomness in Economics presents a variety of cutting edge papers by leading economists, scientists, and philosophers. Topics explored include nonlinear macroeconomic modelling, agent–based modelling, information–theoretic modelling of financial markets, bounded rationality, and emergent complexity. Utilizing an interdisciplinary approach, Nonlinearity, Complexity and Randomness in Economics reveals how true intellectual rigour in economics requires a basis in algorithmic, computable mathematical foundations.
