+====Does Empirical Embeddedness Matter? Methodological Issues on Agent-Based Models for Analytical Social Science====

+** Abstract:** The paper deals with the use of empirical data in social science agent-based models. Agent-based models are too often viewed just as highly abstract thought experiments conducted in artificial worlds, in which the purpose is to generate and not to test theoretical hypotheses in an empirical way. On the contrary, they should be viewed as models that need to be embedded into **empirical data both to allow the calibration and the validation** of their findings. As a consequence, the search for strategies to find and extract data from reality, and integrate agent-based models with other traditional empirical social science methods, such as qualitative, quantitative, experimental and participatory methods, becomes a fundamental step of the modelling process. The paper argues that the characteristics of the empirical target matter. According to characteristics of the target, ABMs can be differentiated into case-based models, typifications and theoretical abstractions. These differences pose different challenges for empirical data gathering, and imply the use of different validation strategies.

+====Critique on agent-based simulation====
+Cosma Shalizi (blog: three-toed sloth) has many good links where you might find something relevant. Here's some:
+http://cscs.umich.edu/~crshalizi/notebooks/agent-based-modeling.html
+http://www.cscs.umich.edu/~crshalizi/weblog/517.html
+and his 'chaos, complexity and inference' course which puts ABM in a wider context:
+http://cscs.umich.edu/~crshalizi/weblog/598.html
+Somewhere - I can't find where - he also links to this paper:
+http://www.isi.edu/~lerman/papers/isitr529.pdf
+"A General Methodology for Mathematical Analysis of Multi-Agent Systems" which attempts to show that at least some set of ABMs can be replaced with differential equations - so an implicit critique.
