In recent years nonlinearities have gained increasing importance in
economic and econometric research, particularly after the financial
crisis and the economic downturn after 2007. This book contains
theoretical, computational and empirical papers that incorporate
nonlinearities in econometric models and apply them to real economic
problems. It intends to serve as an inspiration for researchers to take
potential nonlinearities in account. Researchers should be aware of
applying linear model-types spuriously to problems which include
non-linear features. It is indispensable to use the correct model type
in order to avoid biased recommendations for economic policy.
