As many more clinical trials collect economic information within their study design, so health economics analysts are increasingly working with patient-level data on both costs and effects. In this paper, we review recent advances in the use of statistical methods for economic analysis of information collected alongside clinical trials. In particular, we focus on the handling and presentation o...

Epistasis that may explain a large portion of the phenotypic variation for complex economic traits of animals has been ignored in many genetic association studies. A Baysian method was introduced to draw inferences about multilocus genotypic effects based on their marginal posterior distributions by a Gibbs sampler. A simulation study was conducted to provide statistical powers under various un...

Designing an online resource exchange system is challenging, especially when that system is decentralized and its members fully autonomous. To facilitate the system architecture and protocol design, it is important to understand the behavior of the users and the impact system parameters play on their actions. In this paper we identify key attributes, such as trust and the rate of contribution, ...

I examine the incentives for software providers to design appropriate user interfaces. There are two sorts of costs involved when one uses software: the fixed cost of learning to use a piece of software and the variable cost of operating the software. I show that a monopoly provider of software generally invests the right amount of resources in making the software easy to learn, but too little ...

Spacecraft and launch systems are examples of complex products which require a careful balance between competing concerns, such as performance, weight, and reliability, to serve their mission. Complexity requires design by large engineering organizations, so this balance must be achieved across many teams of people working on various components. This paper uses optimization theory to derive a m...
