The example of inside lag in monetary policy from the options provided is:
Members of the Board of Governors refuse to lower the discount rate until several months after a recession has begun.
Inside lag refers to the delay between the recognition of an economic issue (such as a recession) and the implementation of policy measures to address it. In this case, the delay in lowering the discount rate indicates an inside lag, as the decision-makers (the Board of Governors) are not acting promptly in response to the economic conditions.
