In this paper, we examine a supply chain in which a single supplier sells to a downstream newsvendor-type retailer. We make two assumptions that enrich this simple and well-understood model. First, we consider a multi-period model, in which the sequence of events is as follows. In a period, t,...

We study the impact of the Covid-19 pandemic on Euro Area inflation and how it compares to the experiences of other countries, such as the United States, over the two-year period 2020-21. Our model-based calibration exercises deliver four key results: 1) Compositional effects – the switch from...

This paper provides direct empirical evidence on the relationship between technology and firms' global sourcing strategies. Using new data on U.S. firms' decisions to contract for manufacturing services from domestic or foreign suppliers, I show that a firm's adoption of communication technology...

The United States imports intermediate inputs from China, helping downstream US firms to expand employment. Using a cross-regional reduced-form specification but differing from the existing literature, this paper (a) incorporates a supply chain perspective, (b) uses intermediate input imports...

We study how the technological importance of inputs – measured by cost shares – is related to the decision to “make” or “buy” that input. Using detailed French international trade data and an instrumental variable approach based on self-constructed input-output tables, we show that...

We develop a tractable model of strategic debt renegotiation in which businesses are sequentially interconnected through their liabilities. This financing structure, which we refer to as a debt chain, gives rise to externalities as a lender’s willingness to provide concessions to his...

More advanced technologies demand higher degrees of specialization - and longer chains of production connecting raw inputs to final outputs. Longer production chains are subject to a "weakest link" effect: they are more fragile and more prone to failure. Optimal chain length is determined by the...

This paper provides both a conceptual framework for decomposing a country's gross exports into value-added components by source and a new bilateral database on value-added trade. Our parsimonious framework integrates all previous measures of vertical specialization and value-added trade in the...

This paper updates the conceptual foundations for measuring real effective exchange rates (REERs) to allow for vertical specialization in trade. We derive a value-added REER describing how demand for the value added that a country produces changes as the price of its value added changes relative...

We develop a property-rights model of the firm in which production entails a continuum of uniquely sequenced stages. In each stage, a final-good producer contracts with a distinct supplier for the procurement of a customized stage-specific component. Our model yields a sharp characterization for...
