We study the effect of hospital adoption of electronic medical records (EMRs) on health outcomes, particularly patient safety indicators (PSIs). We find evidence of a positive impact of EMRs on PSIs via decision support rather than care coordination. Consistent with this mechanism, we find an...

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...

We examine the relationship between the adoption of EMR and hospital operating costs. We first identify a puzzle that has been seen in prior studies: Adoption of EMR is associated with a slight cost increase. We draw on the literature on IT and productivity to demonstrate that the average effect...

Does adoption of broadband internet in firms enhance labor productivity and increase wages? And is this technological change skill biased or factor neutral? We exploit rich Norwegian data to answer these questions. A public program with limited funding rolled out broadband access points, and...

This paper defines and analyzes a "sparse max" operator, which is a less than fully attentive and rational version of the traditional max operator. The agent builds (as economists do) a simplified model of the world which is sparse, considering only the variables of first-order importance. His...

This paper discusses and illustrates identification problems in personality psychology. The measures used by psychologists to infer traits are based on behaviors, broadly defined. These behaviors are produced from multiple traits interacting with incentives in situations. In general, measures...

We test empirically for evidence that government tariff-setting behavior depends on the degree of discretion with which policy-makers are endowed. We do this by studying government tariff choices under two distinct environments. One environment is that of tariffs set under the Escape Clause...

We present a model of endogenous firm growth with R&D investment and stochastic innovation as the engines of growth. The model for firm growth is a partial equilibrium model drawing on the quality ladder models in the macro growth literature, but also on the literature on patent races and the...

A vibrant literature has emerged that suggests willingness to pay and willingness to accept measures of value are quite different for inexperienced consumers but that value differences erode with market experience. One potential shortcoming of this literature is that market experience is...

This study explores the role of investor sentiment in a broad set of anomalies in cross-sectional stock returns. We consider a setting where the presence of market-wide sentiment is combined with the argument that overpricing should be more prevalent than underpricing, due to short-sale...
