State Space Models

All state space models are written and estimated in the R programming language. The models are available here with instructions and R procedures for manipulating the models here here.

The Minsky-Kindleberger Framework


 

In a prior post on Theories of Great Depressions, the major input variable to the Systems Model was a "Shock". The shock could just be non-random "innovations" or it could be the outputs of some other system. Shocks themselves are "explained" by the Minsky-Kindleberger Framework, diagramed above.

During periods of Economic Stability, lending institutions start to expand credit. Expanded credit leads to more Speculation. When some trigger (shock) comes along (e.g., a bank failure, war, etc.) sellers panic sets in which leads to an Economic Crash, implementation of tighter Regulation and a return to Stability. 

The Crash can be prevented if a Lenders of Last Resort (Central Bank, Governments, or International Institutions such as the IMF) step in to provide liquidity and soak up non-performing assets. The model seems to fit the 1929 Great Depression, the 1997 Asian Financial Crisis, the 2000 Dot-com Bubble, the 2008 Global Financial Crisis and the Eurozone sovereign debt crisis (2009-2018).

Technology Long Waves

  


The Kondratiev Wave is an important element of World-Systems Theory. The graphic above is taken from Andreas Goldschmidt and gives historical specifics for technological cycles. Goldschmidt's formulation allows for the idea to be tested (one of the models I always test), is partially consistent with economic Growth theory (particularly if we do not assume a functional form for exogenous disembodied technological change in the Solow-Swan Model) and I can present some examples.
