17-year-old IISL Fellow's research on the #Evolution of the #PoliticalEconomy uses #SystemDynamics to explore how #VarietiesOfCapitalism perform against each other under #LimitsToGrowth. Nonlinear 11th order system of differential equations causes overshoot, limit cycles & chaos.

Congratulations to @MIT for being ranked the world's top university for the 14th consecutive year in the 2026 @worlduniranking. IISL's research on 'The Evolution of Economic Ecosystems' began at MIT 25 years ago, using #SystemDynamics, which was invented at MIT 70 years ago.

IISL's annual 'Strategic Thought Leadership' Award goes to @MIT Professor & @NobelPrize winner @DAcemogluMIT for his empirically-grounded formal mathematical models of the evolution of the global political economy - the IISL's core mission - which he has called "The Holy Grail".

Congratulations to @MIT for being ranked #1 in the world for the 13th consecutive year in the 2025 @worlduniranking. IISL's research on 'The Evolution of Economic Ecosystems' began at MIT nearly 25 years ago, using #SystemDynamics, which was invented at MIT nearly 70 years ago.

IISL's youngest Fellow and @Stanford sophomore's research uses #SystemDynamics to model how capital & labor interact to co-create & distribute the wealth of nations. If the UK were to join the US as its 51st state, it would be last in terms of GDP per capita behind Mississippi.

Congratulations to IISL's youngest Fellow and @Stanford sophomore who was today awarded a University 'Major Grant' for his #SystemDynamics research: "Toward a Theory of the Evolution of the Global Political Economy: Trajectories of Capitalism and Democracy in the 21st Century".

IISL research on 'The Evolution of the Global Political Economy' long-predicted this ideological gender gap opening as economic growth rates decrease, with 'Coordinated Market Economies' (Germany & South Korea) being more conservative across genders than 'Liberal MEs' of US & UK.

The IISL's 'Evolution of Economic Ecosystems' research long-predicted that slowing economic growth in the 21st century would cause #Democracy to decline in Liberal Market Economies compared to Coordinated Market Economies. IISL's 'Meta-Index of Democracy Indices' confirms this:

IISL's annual 'Strategic Thought Leadership' Award goes to Professor Jorgen Randers for his intellectual courage and innovative research in advancing heterodox economics via #SystemDynamics and his tireless advocacy of #Sustainability dating back 50+ years to the #LimitsToGrowth.

IISL's youngest Fellow and @stanford sophomore's 'Dynamic Theory of the Evolution of Capital Structure': Which is better, debt or equity financing? It depends on the growth rate of the industry. Leverage is helpful in accelerating markets, but harmful in decelerating markets.

Congratulations to the IISL's youngest Fellow and @Stanford sophomore, whose proposal, "Toward a Theory of the Evolution of the Global Political Economy: Integrating Piketty’s Economic Inequality and Summers’ Secular Stagnation", was accepted to a special edition of @ReviewofPE.

Congratulations to the teenage @Stanford @SIEPR & IISL Fellow, who was only 15 when he made this short video of IISL's research on 'The Evolution of Economic Ecosystems' (aka #RedBlue), which now has over 10,000 views. Feel free to view, like & subscribe: https://t.co/FFTTNxA8PU

50+ years ago, the ground-breaking #SystemDynamics #LimitsToGrowth research of @MIT & @ClubOfRome showed that in the 'Status Quo' scenario, 'Industrial Output' would peak mid-21st century. @TheEconomist implied they were wrong as it has not yet happened. https://t.co/38U6cD6d5r

Teenage @Stanford IISL Fellow mathematically proved that offering $100 is a Subgame Perfect Nash Equilibrium of his 'Ultimate Ultimatum Game' (i.e. full altruism is rational under a wide range of discount factors). Almost 1/3 of voters came to this counterintuitive conclusion.

Teenage @Stanford IISL Fellow is conducting independent research on his 'Ultimate Ultimatum Game' which explores the trade-offs between selfishness & altruism, competition & cooperation, efficiency & equ(al)ity. Be the 1st to play. Please vote & retweet. https://t.co/CCfKnNASfT

Example: Round 1, Fund=$100 Player A proposes $50 to Player B B accepts A gets $50, B gets $50 Round 2, Fund=$100+$50=$150 B proposes $1 to A A rejects A gets $0, B gets $0 Round 3, Fund=$150+$0=$150 A proposes $50 to B B accepts A gets $100, B gets $50 Repeat infinitely.

You are given a $100 fund & must propose a split with a stranger. If they accept, you both get the split. If they reject, you both get $0. The roles are then reversed & the new fund to split = previous fund + previously accepted offer. Repeat infinitely. What is your proposal?

IISL's inaugural 'Strategic Thought-Leadership' Award goes to @ProfSteveKeen for his intellectually courageous and innovative research & advocacy in challenging neoclassical economics (e.g. #ClimateCrisis & #MMT) and advancing heterodox economics (via #SystemDynamics & #Minsky).

IISL presents its annual rankings of the world's top universities based on a longitudinal meta-analysis of independent data sources: #1: @Harvard #2: @Stanford #3: @MIT IISL's award-winning research on 'The Evolution of Economic Ecosystems' is/has been based out of all three.

19-year-old IISL Fellow presented his #SystemDynamics research today at the #SVOC #VarietiesOfCapitalism conference in Budapest, explaining why Liberal Market Economies outperformed Coordinated MEs from 1800-1970 and why this has reversed and will continue in the 21st century.

The human population reached #8billion today, during #COP27. #LimitsToGrowth predicted this 'business as usual' scenario 50 years ago using #SystemDynamics. IISL research predicts that when we reach 8 billion again on the way down in 2050 +/-, #Capitalism will be in 'chaos'.
