The Technological Elements of Artificial Intelligence
Taddy, Matthew Alan - 2018
We have seen in the past decade a sharp increase in the extent that companies use data to optimize their businesses. Variously called the `Big Data' or `Data Science' revolution, this has been characterized by massive amounts of data, including unstructured and nontraditional data like text and...

Organizing the Global Value Chain
Antras, Pol - 2012
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...

Conceptual Aspects of Global Value Chains
Antras, Pol - 2019
I offer an overview of some key conceptual aspects associated with the rise of global value chains (GVCs). I outline a series of alternative interpretations and definitions of what the rise of GVCs entails, and I trace the implications of these alternative conceptualizations for the measurement...

A Spatial Approach to Energy Economics
Moreno Cruz, Juan Bernardo - 2014
We develop a spatial model of energy exploitation where energy sources are differentiated by their geographic location and energy density. The spatial setting creates a scaling law that magnifies the importance of differences across energy sources. As a result, renewable sources twice as dense,...

Internalizing Global Value Chains : A Firm-Level Analysis
Alfaro, Laura - 2015
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...

Global Value Chains and Effective Exchange Rates at the Country-Sector Level
Patel, Nikhil - 2014
The real effective exchange rate (REER) is one of the most cited statistical constructs in open-economy macroeconomics. We show that the models used to compute these numbers are not rich enough to allow for the rising importance of global value chains. Moreover, because different sectors within...

The Need for (Long) Chains in Kidney Exchange
Ashlagi, Itai - 2012
It has been previously shown that for sufficiently large pools of patient-donor pairs, (almost) efficient kidney exchange can be achieved by using at most 3-way cycles, i.e. by using cycles among no more than 3 patient-donor pairs. However, as kidney exchange has grown in practice, cycles among...

Financing as a Supply Chain : The Capital Structure of Banks and Borrowers
Gornall, Will - 2013
We develop a model of the joint capital structure decisions of banks and their borrowers. Strikingly high bank leverage emerges naturally from the interplay between two sets of forces. First, seniority and diversification reduce bank asset volatility by an order of magnitude relative to that of...
