ABSTRACT Context: natural experiments or quasi-experiments have become quite popular in management research. The differences-in-differences (DiD) estimator is possibly the workhorse of these techniques. Objective: the goal of this paper is to provide a tutorial that serves as practical guide for researchers considering using natural experiments to make causal inferences. Methods: we discuss the DiD advantages, concerns, and tests of validity. We also provide an application of the technique, in which we discuss the effect of government guarantees on banks' degree of risk, using the 2008 financial crisis as a natural experiment. The database used, as well as the Stata and the R scripts containing the analyses, are available as online appendices. Conclusion: DiD may be used to tackle endogeneity concerns when treatment assignment is random.

Presenting an analysis of higher education in eight countries in the Arab Middle East and North Africa, Degrees of Dignity works to dismantle narratives of crisis and assert approaches to institutional reform. Drawing on policy documents, media narratives, interviews, and personal experiences, Elizabeth Buckner explores how apolitical external reform models become contested and modified by local actors in ways that are simultaneously complicated, surprising, and even inspiring. Degrees of Dignity documents how the global discourses of neoliberalism have legitimized specific policy models for higher education reform in the Arab world, including quality assurance, privatization, and internationalization. Through a multi-level and comparative analysis, this book examines how policy models are implemented, with often complex results, in countries throughout the region. Ultimately, Degrees of Dignity calls on the field of higher education development to rethink current approaches to higher education reform: rather than viewing the Arab world as a site for intervention, it argues that the Arab world can act as a source for insight on resilient higher education systems. ; This book has been published with the help of a grant from the Federation for the Humanities and Social Sciences, through the Awards to Scholarly Publications Program, using funds provided by the Social Sciences and Humanities Research Council of Canada.
