Fiscal Policy, Growth, and Design of Stabilization Programs Vito Tanzi The objectives of Fund-supported stabilization programs include a balance of payments viable over the medium run, the promotion of growth under a stable economic environment, price stability, and the prevention of excessive growth in external debt. These objectives do not have the same weight, but each is important in stabilization pro- grams. A narrow interpretation of the Fund's role would emphasize the balance of payments objective and de-emphasize the others. This paper deals with the role of fiscal policy in stabilization pro- grams, emphasizing the structural aspects of fiscal policies since, over the years, these aspects have attracted less attention than has demand management. The Baker initiative of October 1985 called attention to the importance of these structural aspects. The paper does not discuss other elements of program design, such as incentive measures imple- mented through the exchange rate, through import liberalization, through financial deregulation, or through pricing policy, even though these structural elements are obviously important. In coun- tries where institutions necessary for the effective use of other policies are not adequately developed, fiscal policy may be the main avenue to economic development and stability, although, unfortunately, politi- cal pressures, external shocks, and administrative shortcomings have frequently weakened government control over this instrument. Tax evasion, inflation, and the proliferation of exonerations have reduced the government's ability to control tax revenues, while political pres- sures, fragmentation of the public sector, and inadequate monitoring 121 ©International Monetary Fund.

Far from being the stabilizing factor in the economy that it should be, fiscal policy has itself, in too many instances, become a major destabilizing force contributing to disequilibrium in the exter- nal sector.1 In recent years the connection between fiscal developments and external sector developments has been increasingly recognized. Some have gone as far as to suggest a "fiscal approach to the balance of payments" that considers fiscal disequilibrium as the main cause of external imbalances.2 Although growth was always a primary objective of economic policy, the sustained rates of growth experienced by most countries until the mid-1970s (except for occasional and transitory periods of balance of payments difficulties) made it possible for the Fund, in negotiating stabilization programs, to concentrate on the objective of stabilization in which it had more expertise and an accepted mandate. The increase in oil prices during the 1970s and especially the more recent debt crisis accompanied by the sharp fall in commodity prices brought about a new environment in which external sector disequilibrium could not be easily financed. This forced many countries to pursue (over longer periods than had earlier been the case) stabilization policies aimed at reducing external imbalances or the rate of inflation, policies that some critics considered as inimical to growth. In the face of external shocks, some countries (for example, the Republic of Korea) succeeded in stabilizing their economies and in advancing once again along the road of economic development. Others were less successful. When the need to pursue stabilization policies extended over several years, the short-run political costs of these policies began to loom larger than the longer-run economic benefits; political fatigue set in and some countries became restive under the harness of traditional stabilization programs. The cries of critics that stabilization policies were inhibiting growth became louder and attracted a larger following. Critics advised policymakers to aban- 1 In this paper the impact of fiscal developments on the balance of payments is empha- sized. But, of course, the relationship is not unidirectional. In some cases fiscal dis- equilibrium may initially be created by developments in the balance of payments (say, a fall in export prices). In those cases the important question is whether the government should finance the shortcoming, or whether it should immediately or progressively lower domestic spending to reflect the lower real income of the country. On this, see Tanzi (1986), pp. 88-91; Tabellini (1985); and Chu (1987). 2 For the connection between the fiscal deficit and the balance of payments, see Kelly (1982), pp. 561-602.

They espoused the position that inflation is a lesser evil than stagnation and that the external sector can be kept in equilibrium through quantitative restrictions and export subsidies, or by repudiating external debt obligations. As already mentioned, stabilization and growth have always been legitimate policy objectives. Although in the past it was thought that at any given moment a country could focus on policies aimed specifically at one or the other of these objectives, the view that it is unwise to separate these objectives currently predominates. Stabilization pro- grams must pay attention to growth to ensure that stability is not won at the price of stagnation.3 Growth policy must pay attention to sta- bility to ensure that the pursuit of growth is not aborted by excessive inflation or by pressures on the external sector, as has happened in several cases in recent years. Growth without stability may be tech- nically impossible over the longer run; stability without growth may be politically impossible except in the short run. This paper attempts to reformulate the fiscal design of stabilization programs in order to emphasize the growth objective. If stabilization were the only objective of economic policy, stabiliza- tion programs could rely mostly on traditional demand-management policies.4 Stabilization with growth, however, requires that demand- management policies be complemented by policies aimed at in- creasing potential output. Misguided structural policies have reduced potential output by misallocating resources and by reducing the rate of growth of the factors of production. They have thus been the main cause of stagnation and a contributor to economic instability. The design of adjustment programs should integrate stabilization with growth, or demand-management policies with structural, supply-side policies. Fiscal Policy and the Design of Fund Programs Stabilization programs can, in theory, emphasize either specific or general fiscal policies. For example, the country and the Fund could 3 This is particularly important in order to reduce over time the burden of the foreign debt of the countries. 4 But, of course, changes in the exchange rate, which have often been part of traditional stabilization programs, have incentive effects in addition to their demand-management effect. ©International Monetary Fund. Not for Redistribution 124 VITO TANZI agree on a whole range of specific fiscal measures, such as changes in various taxes and tax rates and changes in specific public ex- penditures, subsidies, and public utility rates. These measures, how- ever, would have to add up to the required adjustment in aggregate demand and supply. They must reduce the balance of payments dis- equilibrium and the rate of inflation to the desired level by reducing aggregate demand and by increasing aggregate supply. For identifica- tion I shall call this the microeconomic approach to stabilization pro- grams, an approach that explicitly recognizes both the demand- management and the supply-management aspects of fiscal policy. It recognizes that fiscal policy changes usually affect not only aggregate demand but also aggregate supply.5 Alternatively, the country and the Fund could limit their agreement on a program to general, macroeconomic variables. In the extreme version of this alternative, the Fund and the country might not even discuss specific fiscal policies, but would limit not only their agreement but also their discussions to the size of the fiscal deficit and to the expansion of bank credit associated with that deficit. If specific poli- cies are discussed, it would be to assess their immediate impact on the size of the fiscal deficit and on aggregate demand. In this approach, supply-side aspects of fiscal policy (what I have called the supply-management aspects) would be largely ignored. I shall call this the macroeconomic approach to stabilization policy. This approach implies that once the size of the deficit has been determined, the balance of payments consequences of that deficit have also been determined regardless of the specific measures that the country will employ to achieve the stipulated level of fiscal deficit.6 Whether the 5 Over the years, what I have called the supply-management aspect of fiscal policy has received far less attention than the more traditional demand-management aspect. To put it differently, price (or micro) theory was rarely integrated with income (or macro) theory. Fiscal policy based on the Keynesian framework normally concentrated on the effects of changes in tax levels and public spending levels on aggregate demand. Supply management is a relative newcomer
