As the February 23 election approaches, Germany’s economy is at a crossroads. In this op-ed, Gernot Müller and I explore Germany’s economic stagnation. It is not just about weak demand—it’s a deeper supply-side problem. theconversation.com/german-elect... #EconSky #gdp #numbersday

German election: a triple crisis looms large at the heart of the economy

High energy prices, a weak labour force and low productivity growth are behind the ailing German economy – and voters are feeling the pinch.

A quantitative HANK model estimated with linear methods where aggregate uncertainty interacts with the illiquidity friction to drive business cycles and asset returns, from Cosmin L. Ilut, Ralph Luetticke, and Martin Schneider www.nber.org/papers/w33331

We further exploit the tractability of ambiguity to study the importance of precautionary pricing of firms. So much to unpack! Enjoy the holidays. : )

Our model can also explain averages better: Capital premium is 3.2% ambiguity + 2.3% illiquidity. Average wealth inequality is higher as well and there is a larger fraction of HtM households.

Ambiguity about TFP jointly explains more than 70% of the cyclical variation in key macroeconomic aggregates as well as in the excess return on capital and the real interest rate.

Portfolio substitution by rich capital owners is crucial to fit investment and return dynamics. They worry about low dividends + trading frictions, very different from the rep.agent who mostly earns labor income. This leads to a greater fall in investment and asset prices.

We exploit the tractability of ambiguity to fully estimate the effects of aggregate uncertainty on the ergodic distribution and dynamics of a 2-asset HANK model, while still using first-order perturbation techniques. We find a strong interaction of ambiguity with heterogeneity!

Ana has consistently demonstrated her ability to solve complex models, derive intuitive closed-form expressions, and effectively connect these models with empirical data. That's the perfect skill set for a modern macroeconomist!

Ana has another completed paper on optimal fiscal policy within the New Keynesian network model, co-authored with my colleague Gernot Müller as well as two papers on precautionary household behavior in response to risk and its significance for the business cycle.

Her JMP finds cost-push inflation to be twice as high once she introduces state-dep. pricing into NK network models. State-dep. price adjustments occur in 70% of US sectors and account for a substantial portion of price changes. Sectors with low price avg volatility matter most!
