This book about mathematics and methodology for economics is the result
of the lifelong experience of the authors. It is written for university
students as well as for students of applied sciences. This
self-contained book does not assume any previous knowledge of high
school mathematics and helps understanding the basics of economic
theory-building. Starting from set theory it thoroughly discusses linear
and non-linear functions, differential equations, difference equations,
and all necessary theoretical constructs for building sound economic
models. The authors also present a solid introduction to linear
optimisation and game theory using production systems. A detailed
discussion on market equilibrium, in particular on Nash Equilibrium, and
on non-linear optimisation is also provided. Throughout the book the
student is well supplied with numerous examples, some 2000 problems and
their solutions to apply the knowledge to economic theories and models.
