Asset prices are well known to lead the business cycle, yet most modern models generate
movements in prices and quantities that are roughly contemporaneous. In US data, for
example, equity returns and the short-term interest rate lead GDP growth by one or two
quarters, while growth rates of consumption, investment, and employment growth move
more or less together with GDP. We show how all of these features can be reproduced in
variant of the Kydland-Prescott model with recursive preferences and a predictable component in productivity growth. A loglinear approximation is featured throughout; as a result,
interest rates have a linear structure similar to popular affine models.
