In particular, CD implies a deterministic comparative static of a change in decision when risk changes, but SD does not have such an implication. In this paper, we propose the first test of central dominance, which amounts to checking a functional inequality. We derive the asymptotic distribution of a lower bound of the proposed test and suggest a bootstrap procedure to compute the critical values. We also conduct simulations to evaluate the performance of this test. Our empirical study finds clear evidence of CD relations between the S&P 500 index return distributions during 2001–2013 and results in unambiguous implications for investment decisions. © 2016 Elsevier B.V. | 關聯: | Journal of Econometrics, 196(2), 368-378 | 資料類型: | article | DOI: | http://dx.doi.org/10.1016/j.jeconom.2016.07.008 |
