We present an equilibrium theory of the organization of work in an economy where knowledge is an essential input in production and agents are heterogeneous in skill. Agents organize production by matching with others in knowledge hierarchies designed to use and communicate their knowledge efficiently. Relative to autarky, organization leads to larger(More)
Author disambiguation is the problem of determining whether records in a publications database refer to the same person. A common supervised machine learning approach is to build a classifier to predict whether a pair of records is coreferent, followed by a clustering step to enforce transitivity. However, this approach ignores powerful evidence obtainable(More)
A fundamental challenge in Internet computing (IC) is to efficiently schedule computations having complex inter job dependencies, given the unpredictability of remote machines, in availability and time of access. The recent IC scheduling theory focuses on these sources of unpredictability by crafting schedules that maximize the number of executable jobs at(More)
Information retrieval systems conventionally assess document relevance using the bag of words model. Consequently, relevance scores of documents retrieved for different queries are often difficult to compare, as they are computed on different (or even disjoint) sets of textual features. Many tasks, such as federation of search results or global thresholding(More)
We propose a broad generalization of standard choice-theoretic welfare economics that encompasses a wide variety of nonstandard behavioral models. Our approach exploits the coherent aspects of choice that those positive models typically attempt to capture. It replaces the standard revealed preference relation with an unambiguous choice relation: roughly, x(More)
This paper studies how the effects of government spending vary with the economic environment. Using a panel of OECD countries, we identify fiscal shocks as residuals from an estimated spending rule and trace their macroeconomic impact under different conditions regarding the exchange rate regime, public indebtedness, and health of the financial system. The(More)
Recent work in deduplication has shown that collective deduplication of different attribute types can improve performance. But although these techniques <i>cluster</i> the attributes collectively, they do not <i>model</i> them collectively. For example, in citations in the research literature, canonical venue strings and title strings are dependent --(More)
