Abstract:

Does growth in the manufacturing sector of an economy spillover to agriculture, or do sectors share similar growth rates only when they share some common exogenous stimuli? The limited number of investigations of this issue, for cross-sections of countries, have found some evidence in favour of spillovers, though the methodologies used cannot readily separate correlation from causation. Adapting the Feder (1982) model of sectoral externalities to a time-series context, we examine how far agricultural output in Malaysia has been affected by inter-sectoral spillovers. Our results suggest that expansion of manufacturing output, though associated with reduced agricultural output in the short-run, is associated with agricultural expansion over the long-run. Service output growth on the other hand seems to have been inimical to agricultural growth in both the short- and long-runs, while causality testing supports the case for spillovers rather than 'common causes'. Evidence on sectoral productivity is consistent with neoclassical arguments suggesting that the benefits of higher productivity in manufacturing tend to spill over to agriculture, encouraging productivity convergence.
