World-System Steady State Or Collapse

 

  State Space Model Estimation The Measurement Matrix for the  state space models  was constructed using  Principal Components Analysis  with  standardized  data from the  World Development Indicators . The statistical analysis was conducted in an extension of the  dse package . The package is currently supported by an online portal ( here ) and can be downloaded, with the R-programming language, for any personal computer  here .  Code for the state space  Dynamic Component models (DCMs)  is available on my Google drive ( here ) and referenced in each post. Atlanta Fed Economy Now My approach to forecasting is similar to the  EconomyNow model used by the Atlanta Federal Reserve . Since the new Republican Administration is signaling that they would like to eliminate the Federal Reserve, the app might well not be available in the future. While the app is still available, there have been some interesting development...

  From the perspective of Systems Theory (and a lot of commentary), there are three general futures for the World System: (1) Unlimited and Unending Exponential Growth , (2) Steady State Economy and (3) Growth and Collapse . My guess is that most people don't think much about these scenarios and assume that, in the future, things will continue pretty much as they have in the past (the Business-As-Usual Scenario, BAU ). Except for the short-term, BAU is the least likely scenario! This blog explores these and other scenarios using statistically estimated state-space time series models based on data from the World Bank (the World Development Indicators or WDI ) and other sources. All of these future modes of Development are considered by the Intergovernmental Panel on Climate Change  ( IPCC ) in their published Emission Scenarios (graphic above). There most likely scenarios are RCP8.5 (red line above, Growth and Steady State), RCP6 (black line, Growth and Collapse) and RCP2....
