Crowding Out in the UK within an Optimal Control Framework

In: Journal of public policy, Band 2, Heft 1, S. 31-51

Abstract

ABSTRACTAn important issue in the discussion of fiscal policy is the contention that the public sector could expand only at the expense of the private sector, which must contract to provide the necessary room. This paper is concerned with 'financial' crowding out, which relates to the financing of public expenditure, rather than resource crowding out, which relates to the size of public expenditure. The paper attempts to determine empirically, using the National Institute of Economic and Social Research (NIESR) macroeconomic model of the UK economy, whether fiscal actions under different modes of finance affect some strategic economic variables. The paper utilises techniques of optimal control, which are considered superior to simulation. The main conclusion of the paper is that there is no significant crowding out in the NIESR model; it is, nevertheless, important to distinguish between money-financed and bond-financed increases in government expenditure.
