This paper attempts to reconcile the contradictory findings in the debate over school resources and school effectiveness by highlighting the role of aggregation in the presence of omitted variables bias. While data aggregation for well-specified linear models yields unbiased parameter estimates,...

A simple yet easy to implement method is proposed to further improve the finite sample approximation by central limit theorems for aggregate efficiency. By adopt- ing the correction method in Simar and Zelenyuk (2020, EJOR), we further propose plugging the bias-corrected mean efficiency estimate...

Many believe that we ought to save a large number from being permanently bedridden rather than save one from death. Many also believe that we ought to save one from death rather than a multitude from a very minor harm, no matter how large this multitude. I argue that a principle I call...

In this paper, we exploit establishment-level data to examine the relationship between microeconomic productivity dynamics and aggregate productivity growth. After synthesizing the evidence from recent studies, we conduct our own analysis using establishment-level data for U.S. manufacturing...

The study presented here uses data from the NORC General Social Surveys to explore the effects of measurable school characteristics on student achievement. What separates this study from many others is the use of aggregate data on older cohorts, usually associated with research on the influence...

Proper measurement and aggregation of trade costs is of paramount importance for sound academic and policy analysis of the determinants - particularly those of policy - of economic outcomes. The international trade profession has witnessed significant new developments, both on the theoretical...

Explanations of procyclical productivity play a key role in a variety of business-cycle models. Most of these models, however, explain this procyclicality within a representative-firm paradigm. This procedure is misleading. We decompose aggregate productivity changes into several terms, each of...

Can a group be an orthodox rational agent? This requires the group's aggregate preferences to follow expected utility (static rationality) and to evolve by Bayesian updating (dynamic rationality). Group rationality is possible, but the only preference aggregation rules which achieve it (and are...

We study a monopolist that uses the following scheme to gauge market traction for its common-value, excludible product. The monopolist offers its product at a given price, and each potential consumer decides whether to buy it. The contributions are collected. The product is supplied only if the...
