Economics Needs a Reality Check -

1/ Much of what's taught in economics classrooms doesn't match real-world evidence. Image
2/ Markets are complex, dynamic, and shaped by innovation, not static equilibrium.
3/ Power law distributions, not perfect competition, are the rule.
4/ Dominant firms can be efficient, and more firms don't always mean better outcomes.
5/ Income distribution shapes demand and market structure as much as preferences.
6/ We need economic models that reflect reality, not just elegant math.
7/ Policy should be grounded in evidence, not ideology.
8/ It's time for economics—and regulation—to catch up with the real world.
9/ Let's build a better economics for the 21st century.
10/ Want more reality-based #economics? Follow and join the conversation!

Mind you, that’s a very generous definition of “elegant”! Only a Neoclassical could love DSGE mythemagic (a better word than mathematics for what Neoclassical economists actually do).

1/8 Trade deficits: Buffett warns they bleed national wealth. Mosler claims they boost real prosperity. Who’s right? My analysis settles this economic cage fight. Image
2/8 Buffett’s view: A trade deficit = "selling the farm." You exchange assets (bonds, land) for imports today. Over time, foreigners own your capital. Squanderville parable shows how complacency leads to colonization-by-purchase.
3/8 Mosler (MMT) counters: Wealth = your "pile of stuff." Imports grow that pile; exports shrink it. Trade deficits = free goods! Just offset money outflow with government deficits. Simple?

(1/9) Finance YouTubers are screaming Japan will crash the global economy because a municipal bond auction failed. Japan's debt is 250% of GDP, and they think this proves that a collapse is coming. Image
(2/9) They're confusing city budgets with national budgets—it's like panicking that Samsung will shut down because your local electronics store ran out of Galaxy phones.
(3/9) When your city spends $1000, it takes existing money from someone else's bank account. Money just moves around the neighborhood. No new money gets created.

1/ Economist Paul Ormerod's simulations challenge everything we think we know about competition. Image
2/ He modeled 1,000 consumers with different preferences and firms with varied price/quality offers.
3/ Over 40 simulated quarters, prices fell and quality improved—even when a dominant firm remained.

1/ Did you learn in economics that firms always face rising marginal costs as they produce more? The real world tells a different story. Image
2/ Empirical research shows most firms operate with constant or even falling marginal costs as output increases. Efficiency often rises as they approach capacity.
3/ Traditional models assume diminishing marginal productivity, but real businesses get more efficient, not less, with scale.

(1/9) Netflix's Lucifer perfectly explains why economists ignore reality.

When the devil himself tells people who he is, they refuse to believe it.

The same thing happens when banks reveal how money really works; economists just pretend they never heard it. Image
(2/9) Your bank lied to you. They don't take your savings and lend them out. When you get a loan, they literally create new money out of thin air by typing numbers on a computer. Your deposit comes from someone else's loan, not the other way around.
(3/9) Don't believe me? In 2014, the Bank of England admitted it: "Bank lending creates deposits." Explanation: Banks create money when they make loans. They don't need your savings first. Economics textbooks have been teaching the opposite for 100+ years.

1 / Why deficit reduction could CRASH the economy - insights on Trump/Musk economic policies that conventional economists won't tell you. Government debt is NOT like household debt.

2/ The administration aims to cut $1 trillion in spending and eventually eliminate the deficit. But they fundamentally misunderstand how money works in our economy.
2/ The administration aims to cut $1 trillion in spending and eventually eliminate the deficit. But they fundamentally misunderstand how money works in our economy.
3/ Musk told Rogan: "If we don't take action...the entire government budget will be paying interest." But this ignores how our financial system actually operates.
