I am a comparative sociologist by training and taste interested in variations in economic and political knowledge and practice across nations. My first book, Economists and Societies explored the distinctive character of the discipline and profession of economics in three countries. A second book, The Ordinal Society (with Kieran Healy), is under contract. A final book-length project, Measure for Measure: Social Ontologies of Classification will examine the cultural and institutional logic of what we may call “national classificatory styles” across a range of empirical domains. Other research focuses on the valuation of nature in comparative perspective; the moral regulation of states; the comparative study of political organization (with Evan Schofer and Brian Lande), and the microsociology of courtroom exchanges (with Roi Livne). Recent publications include "Ordinalization" (Sociological Theory 2016), “Seeing like a Market” (Socio-Economic Review 2016, co-authored with Kieran Healy) and "State Metrology: the Rating of Sovereigns and the Judgment of Nations" (in Kimberly Morgan and Ann Orloff (eds), The Many Hands of the State, 2017).
