Tariffs, production networks, and spillovers: the case of a US-China trade war

We study the short-run macroeconomic transmission of a US–China tariff war in an open economy multi-sector New Keynesian model with input–output linkages, sectoral nominal rigidities, and heterogeneous currency invoicing. A reciprocal 10 percentage-point tariff increase generates asymmetric incidence: the tariff-imposing country bears more of the inflationary burden, while the targeted country experiences the larger output contraction. Production networks amplify this contraction by propagating the shock beyond the directly tariffed bilateral margin.

A theory of bank liquidity requirements

We develop a general equilibrium theory of financial intermediation and its implications for liquidity regulation. The model is built around an agency problem arising from leveraged intermediation: banks finance loan origination with deposits and face moral hazard in risk management, while holding cash mitigates these incentives at the cost of foregone investment returns. Liquidity demand therefore emerges endogenously from incentive considerations rather than from exposure to exogenous funding shocks.

IFDP Paper: Multi-Plant Firms, Variable Capacity Utilization, and the Aggregate Hours Elasticity

Domenico Ferraro, Giuseppe Fiori, and Damian PierriWe develop a business cycle model with perfectly competitive product and labor markets in which production requires a minimum labor input, generating endogenous capacity utilization. The aggregate production function is kinked, featuring constant returns to scale below capacity—typically in recessions—and decreasing returns at capacity in expansions.
