My paper on fiscal consolidation, its growth effects and implications for debt sustainability assessments is out in the December '25 issue of "Review of Evolutionary Political Economy". I review €zone fiscal consolidations and what the research record shows about growth effects.

German exports in machinery and autos/parts to China have declined strongly. The decline is ~0.8%-points of GDP per year relative to the peak export shares.

John Maynard Keynes wasn’t just a legendary economic and philosophical thinker, he was also an exceptional investor. Managing King’s College Cambridge’s endowment (1922–1946), he delivered ~15% annual investment returns, outperforming equity markets.

Lending rates are falling as monetary policy eases, but unevenly. Household borrowing costs have declined less than those of firms, as household loans are typically tied to longer-term rates and fixed for longer periods, while long-term market rates have fallen only modestly.

The 2002 steel tariffs in the US (under president George W. Bush) created persistent negative employment effects in manufacturing industries that rely on steel as an input - despite being removed after 18 months.

The Austrian National Bank (OeNB) will fund our 3-year project “Understanding people’s views on fiscal policy.” We'll use survey experiments to study expectations about fiscal policy effects, views on propagation mechanisms, fiscal preferences shaped by trust and trade-offs etc.

This is an interesting summary of the IMF's shifting recommendations regarding the appropriate fiscal stance in advanced economies.
Neuer #Fiskalrat-#Budget-Bericht: Doppelbudget ist auf Kurs, aber es bleibt viel zu tun, um die mittelfristigen Budgetziele zu erreichen - insbesondere für das #Budget2027. Implizite Aussage: Die jüngste mediale Aufregung um angeblich explodierende Länder-Defizite bleibt nicht nachvollziehbar. Ein 🧵

Corporate tax cuts have received a lot of intention in debates on reforms as a source of economic growth. Given the variance, there may be cases with positive or negative growth effects of corporate tax cuts, but our results suggest that this focus has often be exaggerated. /7

Our findings are consistent with the nuanced recent theoretical growth literature stressing various (partly competing) channels – such as knock-on effects on R&D incentives or labour supply – through which corporate tax changes can affect growth both positively and negatively. /6

We also find that several factors influence reported estimates, including researcher choices concerning the measurement of growth and corporate taxes, and controlling for other budgetary components. /5

Correcting for this bias, we cannot reject the hypothesis that the effect of corporate taxes on growth is zero. We show that this finding holds when we account for potential endogeneity issues between corporate taxes and growth. /4

According to the average of all estimates, a cut in the corporate tax rate by 10 percentage points would significantly increase annual GDP growth rates by about 0.2 percentage points. This result, however, is driven by publication bias in favour of growth-enhancing effects. /3

We analyse the existing corporate tax-economic growth literature. We collect 441 estimates from 42 primary studies. Reported results are ambiguous: Corporate tax cuts increase, reduce, or do not significantly affect growth /2

Our paper on the inflated effects of corporate tax cuts on economic growth, published in the European Economic Review, is the journal’s most downloaded paper and has attracted the most attention on social media over the last 3 years. It's also among the most widely cited papers🧵

The ultra-rich escape taxation. Effective income tax rates climb steadily for most of the population but fall sharply for billionaires and centi-millionaires.

"The top 0.001% (about 56,000 adults) have 3 times more wealth than half of the entire world population combined."

Greece is running large primary fiscal surpluses of more than 4% of GDP (i.e. revenue > spending excl. interest payments). Italy is also back to running (smaller) primary surpluses. Germany's primary deficit is set to increase as defence and infrastructure spending rises.

Prestige bias in academic research:

Paper submissions from authors affiliated with top-20 ranked institutions receive higher reviewer scores, an effect that vanishes when reviews are blinded. Blinded reviewing narrows disparities in reviewer evaluations and acceptance rates.
