R. Deb et S. Ohseto, Strategy-proof and individually rational social choice functions for public good economies: A note, ECON THEORY, 14(3), 1999, pp. 685-689
Serizawa [3] characterized the set of strategy-proof, individually rational
, no exploitative, and non-bossy social choice functions in economies with
pure public goods. He left an open question whether non-bossiness is necess
ary for his characterization. We will prove that nan-bossiness is implied b
y the other three axioms in his characterization.
