JAPAN: JP1 Growth and Collapse Forecasts

This page is UNDER CONSTRUCTION.

There are two attractive modes for the Economy of Japan: (1) Growth as a regional player in Southeast Asia (AJ) or (2) Business-As-Usual (BAU, see the JP_LM BAU Model). Each of these "attractive" growth modes are compared to a Random Walk (RW or Muddling Through) in the graphic above.

There are also three Geopolitical Collapse Modes or Japan: (1) AXJ, alignment to the Asia Region without regard for the Japanese economy, (2) US, alignment with the United States and (3) W, alignment with the world-system (displayed above).

You can run the JP_LM BAU model using R-code on my Google site (here). Data is from the Maddison Project.

Notes

• Economy of Japan a highly developed mixed economy. It is known as an East Asian model for its public investment into strategic sectors. Japan is the fourth-largest economy in the world by nominal GDP and the fifth-largest by purchasing power parity (PPP).
• Politics of Japan a framework of a dominant-party bicameral parliamentary representative democratic constitutional monarchy. A hereditary monarch, currently Emperor Naruhito, serves as head of state while the Prime Minister of Japan, currently Sanae Takaichi since 2025, serves as the elected head of government.
• History of Japan The first human inhabitants of the Japanese archipelago have been traced to the Paleolithic, around 38–39,000 years ago.^[1] The Jōmon period, named after its cord-marked pottery, was followed by the Yayoi period in the first millennium BC when new inventions were introduced from Asia. During this period, the first known written reference to Japan was recorded in the Chinese Book of Han in the first century AD.
• Economic History of Japan Deflation in Japan started in the early 1990s. On 19 March 2001, the Bank of Japan and the Japanese government tried to eliminate deflation in the economy by reducing interest rates (part of their 'quantitative easing' policy). Despite having interest rates near zero for a long period, this strategy did not succeed.
• Japanese Economic Miracle a period of economic growth in post–World War II Japan. It generally refers to the period from 1955, around which time the per capita gross national income of the country recovered to pre-war levels, and to the onset of the 1973 oil crisis.
• Geography of Japan  an archipelagic country comprising a stratovolcanic archipelago over 3,000 km (1,900 mi) along the Pacific coast of East Asia. It consists of 14,125 islands. The five main islands are Hokkaido, Honshu, Kyushu, Shikoku, and Okinawa. The other 14,120 islands are classified as "remote islands" by the Japanese government. The Ryukyu Islands and Nanpō Islands are south and east of the main islands.

JP_LM Measurement Model

The JP_LM model has three component state variables that explain 100% of the variation in the indicators. JP1 = (Overall Growth), JP2 = (XREAL-HOURS) an Export-Employment controller and JP3 = (HOURS+XREAL - N) a Population-Export-Employment controller.

JP_LM AIC Statistics

All the Akaike Information Criterion (AIC) statistics have overlapping confidence intervals; models have to be chosen on other criteria.

JP_LM BAU Model

The JP_LM BAU model is unstable but easily stabilized by reduction growth rates (see the JP_LM Model in my Google site).
