Field experiments in retailing
… label and national brand products. A large-scale field experiment shows that private label demand is less price sensitive than national brand demand. The estimates from the experimental study are then compared with estimates using the same retailer's transaction history. This allows the evaluation …

A Measure Of Entrepreneurial Risk Preference And Optimism Using Field Experiments
… addresses this issue by examining newly gathered field data which captures the decision making and risk behaviors for a group of high-technology entrepreneurs. Two decision making tasks were used to elicit risk aversion measures and to test for any 'joy of winning' or judgmental errors, possibly …

The determinants of political behavior : evidence from three randomized field experiments
… and competence. I conducted three randomized field experiments in France and combined public electoral records with comprehensive phone and in person surveys to address the following questions: 1) What factors, including costs, information, and attitudes explain people's failure to register …

Combining field experiments, modeling, and analytics for integrated crop-livestock system management
… corn-cattle systems, through combining field experiments, data analytics, and model simulations. A three-year residue grazing trial was conducted on an integrated corn-cattle farm in central Illinois. Two grazing management practices (continuous grazing and strip grazing) were both …

The value of field experiments in estimating demand elasticities and maximizing profit
… are better suited to conducting and analyzing field experiments than to analyzing sophisticated demand models. However, the practical value of using field experiments to optimize marketing decisions remains relatively unstudied. We investigate category pricing decisions that require estimating …

High-accuracy distributed sensor time-space-position information system for captive-carry field experiments
Operational EW test and evaluation experiments require that the position of the aircraft and other moving objects on the range be known precisely as a function of time. Terminal Time-Space-Position Information (TSPI) systems involve the range platforms interacting at close distances and therefore …

Collaborative examinations in asyncronous learning networks : field experiments on collaborative learning through online assessments
… faculty satisfaction, and exam efficiency. A 1*3 field experiment was conducted to compare three exam modes: the traditional exam, the participatory exam, and the collaborative exam. Results show that the collaborative examination significantly enhanced interaction and promoted higher order …

Measuring the effects of online advertising on human behavior using natural and field experiments
… retail sales. Five chapters cover natural and field experiments used to measure these effects for both display and search advertising. The first chapter uses a natural experiment on the Yahoo! Front Page, aided by a flexible semiparametric model, to identify the causal effects of display ad …

Arguments for and field experiments in democratizing digital data collection : the case of Flocktracker
Data is becoming increasingly relevant to urban planning, serving as a key input for many conceptions of a "smart city." However, most urban data generation results from top-down processes, driven by government agencies or large companies. This provides limited opportunities for citizens to …

Essays on the design and targeting of financial products : evidence from field experiments in India
… information. In Chapter 1, I report on a field experiment in India that assesses (1) whether community members have information about one another that can be used to identify high-ability entrepreneurs and (2) whether techniques from mechanism design can be used to elicit truthful reports. …

The decline of Fowler's Toad (Bufo fowleri) in southern Louisiana: molecular genetics, field experiments and landscape studies
Two of the most pervasive threats to species biodiversity are invasive species and habitat loss and degradation. Invasive species are often relatively insensitive to disturbance and many expand their range into disturbed and fragmented habitats. This dissertation uses an interdisciplinary approach …

Goal Setting, Self-help Groups, and Incentives as a Poverty Alleviation Strategy: Evidence from Field Experiments in Indonesia, Colombia and Ethiopia
<p>Abstract: This study uses randomized field experiments conducted in Indonesia, Colombia and Ethiopia to evaluate the efficacy of the combination of goal-setting, self-help groups, and incentives as a poverty alleviation strategy. The experiment in each country had subjects randomly assigned to …

The Role of Trust in Knowledge Acquisition, Technology Adoption and Access to Bank Loans: Results from Field Experiments in the Ecuadorian Amazon
Ecuadorian farmers do not play the investment game (Berg 1995) the same with community farmers as they do with agricultural technicians. Women exhibit a preference for trust in agricultural technicians (vertical trust). Using experimental and survey data from 191 farmers we examine factors …

Improving high-frequency transit reliability : a case study of the MBTA Green Line through simulation and field experiments of real-time control strategies
… The simulation results inform the design of a field experiment, in which headway-based dispatching is implemented at a Green Line branch terminal. Terminal personnel are provided with tablet computers showing departure times optimized by an even-headway policy. When optimized departure times …
