Real-World Economics Review

The ´natural rate of unemployment´, also called ´Non-Accelerating Inflation Rate of Unemployment´ (NAIRU) or ´Non-Accelerating Wage Rate of Unemployment´ (NAWRU), is as, on this blog, Lars Syll states (here and here), a dangerous tool. According to NAIRU/NAWRU theory, a) When unemployment falls below a certain threshold, an inexorable increase in inflation will start. This is simply not true, considering the facts. b) As NAIRU/NAWRU theory is untrue, it can´t be measured by...

from Lars Syll Sixty years ago Milton Friedman wrote an (in)famous article arguing that (1) the natural rate of unemployment was independent of monetary policy and that (2) trying to keep the unemployment rate below the natural rate would only give rise to higher and higher inflation. The hypothesis has always been controversial, and much theoretical and empirical work has questioned the real-world relevance of the idea that unemployment really is independent of monetary policy and that...

Who decides what statistical offices measure and how they measure it? And what are the implicit values embedded in these decisions? Recently, the ILO issued a new manual on measuring productivity. Below, I´ll discuss the questions posed. But for starters, it is essential to realize that economists measure monetary productivity, not physical productivity, which leads to problems with ever-changing prices. This will be part of the discussion. The ILO (International Labour Organization)...

Peak Babies was in 2012. At this moment, we´re back to the level of forty years ago (and the most recent data may well be an overestimate). For the first time in centuries, cohorts entering the global labour market will soon be smaller than the cohorts preceding them. Even when there are significant differences in levels between countries, the years around 1970 were a turning point everywhere. In 1965, the relentless movement towards below-replacement human reproduction started....

from Lars Syll The NAIRU story has always had a very clear policy implication — attempts to promote full employment are doomed to fail since governments and central banks can’t push unemployment below the critical NAIRU threshold without causing harmful runaway inflation. Although a lot of mainstream economists and politicians have a touching faith in the NAIRU fairy tale, it doesn’t hold water when scrutinized. One of the main problems with NAIRU is that it is essentially a timeless...

Like John Stuart Mill, I´m more interested in credit than in money. Developments in the amount of credit provided are much more instructive to the economist than data on money. Look at the graph below (no. 2 in the ECB press release) , a highly Post-Keynesian graph that originated from the pre-Euro Bundesbank and is now published by the European Central Bank. It shows that money growth in the EU is relatively moderate and, more interesting, caused by a combination of 1) lather large...

Hyperinflation is defined as over 50% inflation per month. Let´s define ´normal´ inflation as anything between 0 and 1% per month and anything between 1 and 50% per month as superinflation (1% a month is still a lot, yearly!). Before President Milei, Argentina already knew superinflation. After Milei, inflation accelerated, and the country almost entered a period of hyperinflation. It´s still nearly 200% a year. The maximum monthly increase of the consumer price index was over 24%. These...

from Peter Radford Take four. I continue to listen in on the conversation. The election reverberates loudly around leftish circles. Recriminations mount. Criticisms fly. Finger pointing and over-analysis have become all too common. And this is after just a week. Imagine what a month can produce. So far the central narrative seems to be that the Democrats have become isolated from the most consequential issues that regular folk feel are important. The explanation being that the party is...

Eurostat published new data on employment in Europe. Average employment growth is +0,9%. The average hides stark differences. A Germany-centered core consisting of Germany, Austria, Sweden, Estonia, Finland, and Hungary shows declines. Surprisingly, it excludes Denmark, Belgium and the Netherlands. The South does better. Countries like Portugal, France, Greece, and, especially, Spain post above-average increases. But unemployment in these countries is still high (over 5%), even when EU...

Executive summary: if investments are needed, do not reform. Invest. Investments are the reform. Angus Maddison (historical patterns of growth) and Jan Kregel (leading post-Keynesian economist) were the intellectually dominant forces during my economics study in Groningen around 1982. Let´s apply their frameworks to Greece. Growth, as we measure it, has many sources: increasing the productivity of existing activities (the mechanization of the potato harvest), shifting labour from...
