The question of how technology affects learning has been at the center of recent debates over educational inputs. In 1994, the Israeli State Lottery sponsored the installation of computers in many elementary and middle schools. This program provides an opportunity to estimate the impact of...

Recent studies show that programs offering structured, one-on-one coaching and tutoring tend to have large effects on the academic outcomes of both high school and college students. These programs are often costly to implement and difficult to scale, however, calling into question whether making...

We model early expectations about the value and technological importance ('quality') of a patented innovation as a latent variable common to a set of four indicators: the number of patent claims, forward citations, backward citations and family size. The model is estimated for four technology...

We show that grading standards for primary school exams in England have triggered an inflation of quality indicators in the national performance tables for almost two decades. The cumulative effects have resulted in significant differences in the quality signaled to parents for otherwise...

We structurally estimate a novel job search model with endogenous job search effort, job quality dispersion, and effort monitoring, taking into account that monitoring effects may be mitigated by on-the-job search and search channel substitution. The data are from a randomized experiment...

High rates of understatement are found for many government transfer programs and in many datasets. This understatement has major implications for our understanding of economic well-being and the effects of transfer programs. We provide estimates of the extent of under-reporting for ten transfer...

In this paper, I argue that intangible capital is not a distinct input to production like physical capital or labor but rather it is the glue that creates value from other inputs. This perspective naturally leads to an empirical model in which intangible capital is defined in terms of adjustment...

Concerns about the quality of China's official GDP statistics have been a perennial question in understanding its economic dynamics. We use data on satellite-recorded nighttime lights as an independent benchmark for comparing various published indicators of the state of the Chinese economy....

Previous research found that the initiation of Hospital Compare (HC) quality reporting had little impact on patient outcomes. However little is known about its impact on hospital prices, which may be significant since insurers are positioned to respond to quality information when engaging...

Reputation is critical to foster trust in online marketplaces, yet leaving feedback is a public good that can be under-provided unless buyers are rewarded for it. Signaling theory implies that only high quality sellers would reward buyers for truthful feedback. We explore this scope for...
