Objectives:Group-randomized designs are well suited for studies of professional development because they can accommodate programs that are delivered to intact groups (e.g., schools), the collaborative nature of professional development, and extant teacher/school assignments. Though group designs...

An important element for the public support of policies is their perceived justice. At the same time most policy choices have uncertain outcomes. We report the results of a first experiment investigating just allocations of resources when some recipients are exposed to uncertainty. Although,...

We elicit reciprocal preferences in a firm-worker gift-exchange setting and relate them to actual behavior in a repeated gift-exchange game. We find that only a small minority of 10 percent of workers is materially selfish whereas 90 percent exhibit reciprocal preferences. However, the intensity...

We consider a cheap-talk setting that mimics the situation where an incumbent firm the sender is endowed with incentives to understate the true size of the market demand to two potential entrants the receivers. Although our experimental data reveals that senders messages convey truthful...

The purpose of this paper is to suggest a simple way of determining the thermal characteristic of free-form buildings, which can be applied at an early stage of the design phase. The thermal load of a reference building estimated using TRNSYS 16 is compared with those for various free-form...

Does adverse selection hamper the effectiveness of voluntary risk sharing? How do differences in risk profiles affect adverse selection? We experimentally investigate individuals' willingness to share risks with others. Across treatments we vary how risk profiles differ between individuals. We...

To accurately predict behavior economists need reliable measures of individual time preferences and attitudes toward risk and typically need to assume stability of these characteristics over time and across decision domains. We test the reliability of two choice tasks for eliciting discount...

Storage and transport of temperature sensitive products have become an important issue worldwide. The enhancement of thermal performance of cold application is under investigation and implementing thermal energy storage (TES) systems by using phase change materials (PCM) is one of the solutions...

Turgo turbines are reported to be reliable, robust and able to operate efficiently over a range of flow rates. They are typically used in medium- to high-head applications. In this paper, the operation of a single-jet Turgo turbine outside of this typical application domain is investigated, at...
