Formal Measures in Informal Management: Can a Balanced Scorecard Change a Culture?

By: Robert Gibbons and Robert S. Kaplan

Agency theorists, historically, have analyzed what kinds of performance measures should be used in formal incentive contracts. For example, after Kaplan-Norton proposed a balanced scorecard of both financial and non-financial measures, some envisioned its role only in... View Details

Deferred Acceptance Algorithms: History, Theory, Practice, and Open Questions

By: Alvin E. Roth

The deferred acceptance algorithm proposed by Gale and Shapley (1962) has had a profound influence on market design, both directly, by being adapted into practical matching mechanisms, and, indirectly, by raising new theoretical questions. Deferred acceptance... View Details

Estimating Causal Peer Influence in Homophilous Social Networks by Inferring Latent Locations.

By: Edward McFowland III and Cosma Rohilla Shalizi

Social influence cannot be identified from purely observational data on social networks, because such influence is generically confounded with latent homophily, that is, with a node’s network partners being informative about the node’s attributes and therefore its... View Details

Identifying Sources of Inefficiency in Health Care

By: Amitabh Chandra and Douglas O. Staiger

In medicine, the reasons for variation in treatment rates across hospitals serving similar patients are not well understood. Some interpret this variation as unwarranted and push standardization of care as a way of reducing allocative inefficiency. However, an... View Details

The Political Economy of 'Natural' Disasters

By: Charles Cohen and Eric D. Werker

Natural disasters occur in a political space. Although events beyond our control may trigger a disaster, the level of government preparedness and response greatly determines the extent of suffering incurred by the affected population. We use a political economy model... View Details

Accounting for Crises

By: Venky Nagar and Gwen Yu

We provide among the first empirical evidence consistent with recent macro global-game crisis models, which show that the precision of public signals can coordinate crises (e.g., Angeletos and Werning, 2006; Morris and Shin, 2002, 2003). In these models,... View Details

Minimally Altruistic Wages and Unemployment in a Matching Model

By: Julio J. Rotemberg

This paper presents a model in which firms recruit both unemployed and employed workers by posting vacancies. Firms act monopsonistically and set wages to retain their existing workers as well as to attract new ones. The model differs from Burdett and Mortensen (1998)... View Details

Respect for Improvements and Comparative Statics in Matching Markets

By: Scott Duke Kominers

One of the oldest results in the theory of two-sided matching is the entry comparative static, which shows that under the Gale–Shapley deferred acceptance algorithm, adding a new agent to one side of the market makes all the agents on the other side weakly... View Details
