We study how between-group wealth and size asymmetries affect aggregate rentseeking efforts when two groups compete for the allocation of a pure public good. Unlike with previous analyses on between-group asymmetries, we measure the utility cost of rent-seeking in terms of the loss in private consumption an individual faces when contributing to this activity. Our main result is that fewer betweengroup asymmetries do not necessarily imply greater aggregate rent-seeking efforts. The result is at odds with the commonly held notion that the more homogeneous the contestants in a static rent-seeking model, the greater the aggregate rent-seeking efforts. 1 Cheikbossian (2008) studies group size asymmetries in a context in which the magnitude of the public rents being allocated in the contest is not fixed, but changes with group size. Thus, in Cheikbossian's model group size affects rent-seeking efforts not only through the relative influence of each group but also through the size of the rents being contested. Actually, this feature of the public rents drives the results in his model. Unlike this study, and in the line of Katz et al. (1990) and Riaz et al. (1995), we consider a contest for a unique "pure" public good, which "rents" are constant for each group. Thus, as we will see, the channel through which group size affect aggregate rent-seeking in our framework is totally different to that considered by Cheikbossian (2008).
