ing a problem or puzzle, then building a model to explicate the logic of an explanation for the puzzle or problem, often in the context of a unique case. The method involves several steps. First, the use of narrative to elucidate the principal players, their preferences, the key decision points and possible choices, and the rules of game, all in a textured and sequenced account. Second, building a model of the sequence of interaction, including predicted outcomes. And, third, the evaluation of the model through comparative statics and the testable implications the model generates. The analytic narrative approach is most useful to scholars who seek to evaluate the strength of parsimonious causal mechanisms in the context of a specific and often unique case. The requirement of explicit formal theorizing (or at least theory that could be formalized) compels scholars to make causal statements and to identify a small number of variables as central to understanding the case.Case studies abound in the study of development. A weakness of case studies per se is that there typically exist multiple ways to interpret a given case. How are we to know which interpretation makes most sense? What gives us confidence in the particular interpretation offered? This problem is particularly difficult where the uniqueness of the situation precludes the collection of a data set that encompasses multiple cases. Many scholars augment their case study with a model. The model adds some discipline to the account. For example, observed choices must be consistent with the
