This paper surveys the recent body of work in economics on the importance of global value chains (GVCs) in shaping international trade flows and multinational activity. On the empirical front, we begin reviewing several variants of the "macro approach" to measuring the relevance of global...

How do you measure the value of a commodity that transacts at a price of zero from an economic standpoint? This study examines the potential for and extent of omission and misattribution in standard approaches to economic accounting with regards to open source software, an unpriced commodity in...

In recent decades, advances in information and communication technology and falling trade barriers have led firms to retain within their boundaries and in their domestic economies only a subset of their production stages. A key decision facing firms worldwide is the extent of control to exert...

This paper combines representative worker-level data that cover time-varying job-level task characteristics of an economy over a long time span with sector-level bilateral trade data for merchandize and services. We carefully create longitudinally consistent workplace characteristics from the...

The real effective exchange rate (REER) is one of the most cited statistical constructs in international macroeconomics. With the rising importance of offshoring and outsourcing, the standard measures are increasingly flawed. In addition, because different sectors within a country may...

The fragmentation of production across borders allows firms to make and export final goods, or to perform only intermediate stages of production by processing imported inputs for re-exporting. We examine how financial frictions affect companies' choice between processing and ordinary trade -...

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...

We propose two distinct approaches to the measurement of industry upstreamness (or average distance from final use) and show that they yield an equivalent measure. Furthermore, we provide two additional interpretations of this measure, one of them related to the concept of forward linkages in...
