Higher Order Expansions in the Weak Instrument Case


  • Econometric Society 2004 North American Winter Meetings


  • We provide an argument for the limitation of Edgeworth expansions to many commonly used statistics in the weak instrument framework. However, we show that Edgeworth expansions hold for approximately similar tests regardless of the identification conditions. Finally, we consider simulation techniques to adjust the size of these tests.
