Are apparent findings of nonlinearity due to structural instability in economic time series?

, 2001
Many modelling issues and policy debates in macroeconomics depend on whether macroeconomic times series are best characterized as linear or nonlinear. If departures from linearity exist, it is important to know whether these are endogenously generated ...
