Monte Carlo simulations can be an efficient way to obtain accurate answers for computationally expensive problems. In the field of network exchange theory, finding the probability that an actor is included in an economic exchange is one such problem. An exchange occurs when two connected actors reach agreement to exchange valued goods. The negotiations determine how much each should profit. Research has shown that there is a positive correlation between an actor?s probability of being included and that actor?s profits from exchange. Since the probability of inclusion is a function of the actions of all actors in the network, precise methods to compute a rate of inclusion are computationally expensive for large numbers of connected actors. In this paper, we address this issue by constructing Monte Carlo methods for two existing methods of computing inclusion rates in exchange networks. [ABSTRACT FROM AUTHOR]

Digital Libraries are organized repositories of digitally saved material and are being built to house every type of data imaginable. The digital material of interest here is software applications for conducting experimental research in the area of Sociology. Instead of simply storing the program itself, in which a user would have to download and setup on their own, this paper presents ExNet 3.0, a Digital Library of online accessible software applications that is readily expandable. Applications created for ExNet 3.0 are stored as part of a library of available applications that a person may use a web browser to access and utilize. ExNet 3.0 allows programmers to construct a wide range of online applications for its Digital Library that can then be sequenced together. ExNet 3.0 is based on previous work and design of other software applications in this area. This paper recounts the history and developments that led to ExNet 3.0, as well as, an in depth look at its design. It concludes with a discussion of how ExNet 3.0 might influence the future development of experimental instruments in Sociology and how it can be further improved. [ABSTRACT FROM AUTHOR]
