The aim of this paper is to examine the positive and negative impacts of stock exchange mergers on the informational efficiency of the markets. We consider a range of factors in relation to the stock exchange merger, that can potentially affects market efficiency, after a merger. These factors...

This paper proposes nonparametric consistent tests of conditional stochastic dominance of arbitrary order in a dynamic setting. The novelty of these tests resides on the nonparametric manner of incorporating the information set into the test. The test allows for general forms of unknown serial...

In this paper we propose a new class of tests for the martingale difference hypothesis based on the moment conditions derived by Bierens (1982). In contrast with the existing consistent tests, the proposed test has a standard limiting distribution and is easy to implement. Comparing with the...
