• Testing the Pricing-to-Market Hypothesis: Case of the Transportation Equipment Industry

  Staff Working Paper 2000-8 Lynda Khalaf, Maral Kichian

  Pricing-to-market (PTM) theory suggests that monopolistic firms which export adjust their destination-specific markups in reaction to exchange rate shocks. These adjustments limit changes in the price of their exports.

• Unit-Root Tests and Excess Returns

  Staff Working Paper 1996-10 Marie-Josée Godbout, Simon van Norden

  Several recent papers have presented evidence from foreign exchange and other markets suggesting that the log of excess returns can be characterized as first-order integrated processes (I(1)). This contrasts sharply with the "conventional" wisdom that log prices are integrated of order one I(1) and that log returns should therefore be integrated of order zero I(0), and even more sharply with the view that past returns have no ability to predict future returns (weak market efficiency).
