“…Many studies suggest that the size of any plea-trial sentencing differences likely varies by jurisdiction (Brereton and Casper, 1982;Eisenstein and Jacob, 1977;King et al, 2005;Nardulli, Eisenstein, and Flemming, 1988;Ulmer, 1997). Specifically, scholars have debated the relationship between trial penalties-plea rewards and court caseloads, with some arguing that heavy caseloads drive mode of conviction differences, and others that such differences are independent of caseload pressure (for reviews, see Brereton and Casper, 1982;Dixon, 1995;Farr, 1984;Holmes, Daudistel, and Taggart, 1992;Meeker and Pontell, 1985;Nardulli, Eisenstein, and Flemming, 1988;Wooldredge, 1989). Furthermore, trial penalties have been found to be stronger for defendants with more substantial criminal histories (for example, Smith, 1986;Ulmer, 1997), and to be stronger for blacks (Ulmer, 1997).…”
