 Roemer (1982, 1986c) proposes a renewed economic analysis of Marxian concepts, in particular exploitation. He shows that, even if the theory of labor value is flawed as a causal theory of prices, it may be consistently used in order to measure exploitation and analyze the correlation between exploitation and the class status of individuals. However, he considers that this concept of exploitation is ethically not very appealing, since it roughly amounts to requiring individual consumption to be proportional to labor, and he suggests a different definition of exploitation, in terms of undue advantage due to unequal distribution of some assets. This leads him eventually to merge this line of analysis with the general stream of egalitarian theories of justice. The idea that consumption should be proportional to labor has also received some attention in the theory of fair allocation (Moulin 1990, Roemer &amp; Silvestre 1993). See Roemer (1986a) for a collection of philosophical and economic essays on Marxism. There has been a recent wave of analysis of the concept of exploitation in economics, in particular under the impulsion of Veneziani and Yoshihara (2015, forthcoming).
