The point of intersection between AA and DD curve denotes O simultaneous equilibrium in the goods and financial markets, since the negatively sloped DD curve collects all the combinations of Y and E that are equilibria in the goods market, and the positively sloped AA curve collects all the combinations of Y and E that are equilibria in the financial market. O simultaneous equilibrium in the goods and financial markets, since the positively sloped DD curve collects all the combinations of Y and E that are equilibria in the goods market, and the negatively sloped AA curve collects all the combinations of Y and E that are equilibria in the financial market. O simultaneous disequilibrium in the goods and financial markets, since the positively sloped DD curve collects all the combinations of Y and E that are equilibria in the goods market, and the negatively sloped AA curve collects all the combinations of Y and E that are equilibria in the financial market. O simultaneous equilibrium in the goods and financial markets, since the positively sloped DD curve collects all the combinations of Y and E that are equilibria in the financial market, and the negatively sloped AA curve collects all the combinations of Y and E that are equilibria in the goods market
