Experimentation and Competition [PDF]
This paper examines the effect of competition on firms' efforts to experiment and learn about market demand. Consumers are assumed to know prices only at sellers they have actually visited, but must bear search costs to find the prices of other sellers.

Controlled experimentation in continuous experimentation: Knowledge and challenges
Context: Continuous experimentation and A/B testing is an established industry practice that has been researched for more than 10 years. Our aim is to synthesize the conducted research. Objective: We wanted to find the core constituents of a framework for continuous experimentation and the solutions that are applied within the field.

Monopoly Experimentation [PDF]
This paper considers a firm facing an uncertain demand curve. The firm can experimentally adjust its output in order to gain information that willincrease expected future profits. We examine two basic questions. Under whatconditions is it worthwhile for the firm to experiment?

Experimental evolution: experimental evolution and evolvability [PDF]
The suggestion that there are characteristics of living organisms that have evolved because they increase the rate of evolution is controversial and difficult to study. In this review, we examine the role that experimental evolution might play in resolving this issue.

This chapter reviews experimental evolution. Many of the evolutionary processes extend over long periods of time—long, that is, on human timescales of a few decades. With the resource of a laboratory, we can follow the evolution of large populations over thousands of generations in a few months.

Introduction To date, most animal studies of myocardial ischemia have used open-chest models with direct surgical coronary artery ligation. We aimed to develop a novel, percutaneous, minimally-invasive, closed-chest model of experimental myocardial ...

Experimental and Quasi-Experimental Research in CSCL
(Quasi-)experimental designs play an important role in CSCL research. By actively manipulating one or several independent variables while keeping other influencing factors constant and through the use of randomization, they allow to determine the causal effects of such independent variables on one or more dependent variable(s) that may be of interest ...
