In New Keynesian models, a more persistent demand shock does not always generate a larger output multiplier. The interplay between persistence and monetary policy creates 3 regimes; in the empirically relevant one, the multiplier is hump-shaped.

Collateral protection laws have unintended consequences. We show the 2005 BAPCPA reform protected repo holders but incentivized dealer-banks to dramatically increase leverage, leading to sharper deleveraging during the downturn.

When the Fed sneezes, why does the world catch a cold? While the literature blames financial markets, we show trade is key: a US monetary tightening transmits abroad primarily by crushing US import demand.

Platforms shape what users see and choose. A new paper develops the concept of recommendation power, maps the objectives behind rankings, defaults and prominence, and examines how the EU Digital Markets Act constrains it.

Income uncertainty depresses fertility. I show that income-tested education subsidies mitigate this effect by providing insurance against income risk for households with children.

Labor market conditions shape on-the-job-behavior: as bankers' outside options improve, they are less likely to be dismissed for poor borrower performance. This facilitates riskier lending, with bank and systemic risk rising as a result.

Why are so few refugees hired as apprentices? Our study with 800 German firms points to a large hiring gap. But signals of reliability and motivation matter—and job-specific language training can significantly improve hiring chances.

We study effects of the U.S.-China trade war on third countries, using granular plant-level data. Impacts were highly heterogeneous and largely offsetting, yielding moderately negative net effects. Most economic reallocations happened within MNEs.

Do climate policies hurt industrial competitiveness? New evidence from German manufacturing finds little impact on jobs or wages. But support shielding firms from compliance costs may have significantly reduced plant closures. #ClimatePolicy

New research shows: Moral universalism, caring equally about all people, not just your own group, strongly predicts support for climate policies, from carbon taxes to international burden sharing on who should pay for climate action.

Marina Hoch examines how U.S. post-disaster government aid affects welfare: Although aid crowds out private insurance and encourages risky housing, it raises overall welfare. Providing aid independently of insurance coverage could improve welfare further.

US fertility is at record lows amid scarce, costly housing. One factor: empty-nesters and retirees rarely downsize, concentrating homes among the elderly and squeezing young families in their prime childbearing years. New paper explores the link.

Can Europe integrate its banks without increasing risk? Common deposit insurance removes ring-fencing and improves risk-sharing within banking groups. This encourages integration, but can also increase risk taking, with crucial welfare consequences.

What happens when labor demand expands? We study the
replacements of professors in East Germany after reunification, showing that hiring opened up to candidates from lower-ranked departments while the share of women did not increase. We quantify the associated efficiency losses.

How large should the Central Bank's balance sheet be? How large must it be if one wants to achieve certain objectives in terms of inflation or bank lending? How must fiscal and monetary policy be coordinated?

Why do cash transfers in poor economies raise output but barely move prices? New paper: firms sit on idle capacity, so the local GDP can be high. We estimate a structural model w/ an ongoing RCT in Malawi: the predicted multiplier is between 1.1 and 1.5.

People build mental models on incomplete information, then must revise as new variables appear. We find models are "sticky"—revisions stay anchored to the original. The driver: people allocate less cognitive effort to revising than to forming the model.

Does the spatial structure of housing shape how monetary policy works? This paper shows that higher residential concentration dampens consumption responses to interest rate changes, using a monetary business cycle model and satellite-based geospatial data.

Same machine, opposite lives: In 19th-C, the sewing machine pushed poor women into work, reduced fertility & delayed marriage. Wealthy women instead gained time for more children & civic life—showing how “labor-saving” tech can reinforce inequality.
