... The two key challenges in applied studies are 1) the resolution of statistical and identification problems that confound causal inference (Dehejia and Wahba, 2002;Heckman, et al., 1997;2001;Imbens and Angrist, 1994;LaLonde, 1986;Manski, 1995;Raphael and Stoll, 2006;Rosenbaum and Rubin, 1983;Rubin, 1974;Smith and Todd, 2005, and 2) the development of robust estimates of prices of criminal victimization in the absence of market data (Cohen, 1998;Cohen et al., 1994;Miller, et al., 1996;Miller, et al., 2001;Rajkumar and French, 1997). The scholarly literature on issues of causal inference with observational data is far more extensive than the price literature, and this is reflected in the focus of economic scholarship on theoretical questions with recalcitrant identification problems (Evans and Owens, 2007;Kessler and Levitt, 1997;Knowles, Persico and Todd, 2001;Levitt, 1996;1997;Ludwig and Kling, 2007;Raphael and Winter-Ebner, 2001;Waldfogel, 1993). ...
