Real-World Economics Review

from Adam Smith The difference of natural talents in different men is, in reality, much less than we are aware of; and the very different genius which appears to distinguish men of different professions, when grown up to maturity, is not upon many occasions so much the cause as the effect of the division of labour.  The difference between the most dissimilar characters, between a philosopher [economist] and a common street porter, for example, seems to arise not so much from nature as...

from Steve Keen The key concept in Keynes’s summary was the impact of expectations upon investment, when those expectations were about what might happen in an uncertain future. Investment is undertaken to augment wealth, and yet the outcome of any investment depends upon economic circumstances in the relatively distant future. Since the future cannot be known, investment is necessarily undertaken on the basis of expectations formed under uncertainty. Keynes was at pains to distinguish...

from Lars Syll Kevin Lewis points us to this recent paper, “Can invasive species lead to sedentary behavior? The time use and obesity impacts of a forest-attacking pest,” published in Elsevier’s Journal of Environmental Economics and Management, which has the following abstract: “Invasive species can significantly disrupt environmental quality and flows of ecosystem services and we are still learning about their multidimensional impacts to economic outcomes of interest. In this work, I...

At this moment, there’s quite some ‘graphology’ when it comes to inflation. Here, an example by Paul Krugman. Here, Larry Summers. And an example by a younger chap, Joey Politano. (Caveat: ‘X’ kicked out some links when I was writing this blog (or at least they disappeared), it might happen again)). All of these economists are really ahead of the pack when it comes to knowledge of economic statistics (methodology as well as results). They also know a thing or two about economic theory....

from Blair Fix Have you ever wondered what it takes to become a billionaire? Do you need rare genius? Exceptional acumen? Miraculous foresight? An uncompromising work ethic? On all four counts, the answer is no. It turns out that to become a billionaire, what you really need is the right social setting. You need to live in a society that is suitably rich and appropriately unequal. Without those things, your chances of wearing the billionaire badge are low. In this post, I’ll do the math....

from Dean Baker As everyone learns in Econ 101, and immediately forgets, the purpose of the financial sector is to facilitate transactions and allocate capital. This seems like a simple and obvious point, but you would never know it in most discussions of the financial sector. The point here is that we need finance for these purposes. We don’t need finance to develop elaborate betting games and complex financial instruments. Financial instruments are only useful when they serve the...

from Lars Syll You ask me what all idiosyncrasy is in philosophers? … For instance their lack of the historical sense, their hatred even of the idea of Becoming, their Egyptianism. They imagine that they do honour to a thing by divorcing it from history sub specie æterni—when they make a mummy of it. Friedrich Nietzsche Nowadays there is almost no place whatsoever in economics education for courses in the history of economic thought and economic methodology. This is deeply worrying....

from Jason Hickel and RWER As the climate crisis worsens and the carbon budgets set out by the Paris Agreement shrink, climate scientists and ecologists have increasingly come to highlight economic growth as a matter of concern. Growth drives energy demand up and makes it significantly more difficult – and likely infeasible – for nations to transition to clean energy quickly enough to prevent potentially catastrophic levels of global warming. In recent years, IPCC scientists have argued...

from C. P. Chandrasekhar and Jayati Ghosh The dramatic increase in global oil and food prices from the start of the Ukraine War did not reflect real global supply shortages or demand-supply imbalances. Rather, it reflected the impact of market concentration and financial activity in commodity futures markets, which enabled some large private players particularly global agribusinesses and financial companies to make a killing. This is now so evident from the data that it is more widely...
