Ricardian trade theory — how is this still a thing? On Saturday, April 19th 1817, David Ricardo published The Principles of Political Economy and Taxation, where he laid out the idea of comparative advantage, which since has become the foundation of neoclassical, ‘mainstream’ international trade theory … This week we saw lots of praise of Ricardo, by the likes of The Economist, CNN, Forbes and Vox. Mainstream economists today tend to see the rejection of...

What is Post-Keynesian economics?  [embedded content] Advertisements

Paul Krugman has repeatedly over the years argued that we should continue to use neoclassical hobby horses like IS-LM and AS-AD models. Here’s one example: So why do AS-AD? … We do want, somewhere along the way, to get across the notion of the self-correcting economy, the notion that in the long run, we may all be dead, but that we also have a tendency to return to full employment via price flexibility. Or to put it differently, you do want somehow to make clear the notion...

In the 1870s, a handful of aspiring economists hoped to make economics a science as reputable as physics. Awed by Newton’s insights on the physical laws of motion – laws that so elegantly describe the trajectory of falling apples and orbiting moons – they sought to create an economic theory that matched his legacy. And so pioneering economists such as William Stanley Jevons and Léon Walras drew their diagrams in clear imitation of Newton’s style and, inspired by the way that...

David Ricardo and comparative advantage — a bicentennial assessment Two hundred years ago, on 19 April 1817, David Ricardo’s Principles was published. In it he presented a theory that was meant to explain why countries trade and, based on the concept of opportunity cost, how the pattern of export and import is ruled by countries exporting goods in which they have comparative advantage and importing goods in which they have a comparative disadvantage....

Is having infinitely many models really a sign of progress in economics? In Dani Rodrik’s Economics Rules it is argud that ‘the multiplicity of models is economics’ strength,’ and that a science that has a different model for everything is non-problematic, since economic models are cases that come with explicit user’s guides — teaching notes on how to apply them. That’s because they are transparent about their critical assumptions and behavioral...

Cutting wages is no panacea Falling wages might provide a short-term boost to corporate profits, but the reduced purchasing power of working people would soon cause people to buy less. That is disastrous in advanced capitalist countries, where consumer spending generally accounts for anywhere from 60 to 70 percent of gross domestic product … Falling wages were a reality during the Great Depression, but that didn’t help matters. By 1933 in the United States,...

Learning to think like an economist It takes some courage, maturity, and perception for the self-discovery that one is engaged in a fraudulent enterprise … Our teachers never talked about ideologies or the larger issues, and seemed content with discussing arcane mathematics — DELIBERATE deception involves knowing the truth and then using lies to hide it.This does not seem to be the modus operandi. Rather, after the initial discomfort of swallowing certain...
