Our new methodology builds an inter-country input-output table that distinguishes green products from the rest, allowing us to assess vulnerabilities in green value chains. In a multi-country, multi-sector model, our table reveals that a decoupling of green supply chains between a US-centric West and a China-centric East could globally cut trade in green products by up to 20%, lower welfare by up to 3% and raise yearly global greenhouse gas emissions by about 50 million tonnes.

Akos Horvath and Benjamin S. KayBuilding on queuing theory, we develop and empirically validate a novel theoretical model of residential mortgage supply. Our model gives insight into how the stochastic arrival and sequential servicing of loan applications affect mortgage origination. The model provides closed-form predictions for lenders’ optimal response to changes in the level and price elasticity of mortgage demand.

Dario Caldara, Haroon Mumtaz, and Molin ZhongWe characterize asymmetric tail risk across over one hundred U.S. macroeconomic and financial variables using a dynamic factor model with stochastic volatility. The model unifies growth-at-risk, inflation-at-risk, and sectoral heterogeneity through common factors whose volatility responds endogenously to shocks, combined with heterogeneous factor loadings.

Nils Gornemann, Eugenio Rojas, Felipe SaffieDoes global financial risk affect long-run growth? Using a panel state-space model for emerging and advanced small open economies, we measure the effects of U.S. monetary policy uncertainty shocks. A one-standard-deviation shock lowers the level of the stochastic trend in emerging markets by at least 25 basis points after three years, with little effect in advanced economies.
