KEYNESIAN CROSS: The standard diagram used in Keynesian economics to identify the equilibrium level of aggregate output (that is, gross domestic product), with aggregate expenditures measured on the vertical axis, and aggregate output measured on the horizontal axis. This diagram contains two key lines, the aggregate expenditure line and the 45-degree line. Intersection between these lines indicates equilibrium aggregate output. This intersection, or cross, is what gives rise to the name.

DECISION LAG The time lag that it takes government leaders and policy makers to determine the appropriate government action needed to address an economic problem. The decision lag arises because it takes time for policy makers to chose among the array of possible policy actions, each with assorted consequences that appeal differently to different political constituencies. This "inside lag" is one of four policy lags associated with monetary and fiscal policy. The other two "inside lags" are recognition lag and implementation lag, and one "outside lag" is implementation lag. All four policy lags can reduce the effectiveness of business-cycle stabilization policies and can even destabilize the economy.
