This paper develops estimation methods for network formation using observed data from a single large network. We characterize network formation as a simultaneousmove game with incomplete information, where we allow for utility externalities from indirect friends such as friends in common, so the expected utility from direct friends can be nonlinear. Nonlinearity poses a challenge in estimation ...

Crop models need accurate simulation of the interdependent processes of crop development and leaf area production. Crop development proceeds according to genotype characteristics and environmental influences, specifically temperature and photoperiod. It can be partly described by thermal requirements for development intervals and coefficients that describe genotype adaptation. The objectives of...

Extending an earlier simultaneous comparison of the three Synoptic Gospels to determine the probability of literary interdependence among them, this study continues the investigation by looking at the Gospels two a t a time to evaluate the same probability. The use of OT citations by these Gospels furnishes a standard for ascertaining literary interdependence when it reflects a 79% average of i...

Coevolution between strategy and network structure is established as a means to arrive at the optimal conditions needed to resolve social dilemmas. Yet recent research has highlighted that the interdependence between networks may be just as important as the structure of an individual network. We therefore introduce the coevolution of strategy and network interdependence to see whether this can ...

The objective of this paper is threefold: First is to produce a broad framework of the ways that state regulatory policies are interdependent. Second is to examine the factors that determine the nature of that interdependence. Third is to discuss the governance implications of different types of regulatory interdependencies. This analysis is applied to the spread of a new international sh inspe...

PC-based modeling activity by end-users, used for decision support, is dependent upon information from other models and sources outside the functional unit. Consequently, there is a need for coordination of the various functional unit models that comprise the distributed decision support system. To the extent that the information sharing among these models is timely, current and correct, the re...
