The relationship between foreign aid and economic growth has been the subject of much controversy. A recent theme suggesting that aid promotes growth, but only in a good policy environment has ratchet up that debate. In this paper, we assess the importance of policy and aid in generating growth when the aid, policy, and growth relationship is nonlinear. This allows us to examine the varying effects of aid and policy in different data segments, which we do without imposing any particular structure on the underlying relationship. We find that policy is an important determinant of growth. We also find partial corroboration of the view that aid is growth enhancing in a good policy environment, and some evidence of diminishing returns to aid. These findings suggest that nonlinearities if not appropriately addressed fail to capture the detailed underlying dynamics and thereby mask some key features of the aid-policy-growth relationship.

This paper explores how the optimal mode of public finance depends on the level of economic development. The theoretical analysis suggests that in the presence of capital market imperfection and liquidity shocks, the detrimental effect of inflation on growth is stronger (weaker) at lower (higher) levels of economic development. Consequently, income taxation (seigniorage) is a relatively less distortionary way of financing public expenditure for low-income (high-income) countries. We provide empirical support for our model’s predictions using a panel of 21 Organization for Economic Cooperation and Development countries and 40 developing countries observed over the period 1972–1999.

The growth in the share of resources devoted to food marketed through supermarkets and their accompanying marketing channels has grown at an unprecedented rate in developing countries during the 1990s. This article shows that differences in the relative capital intensity of the modern marketing channels, in contrast to the traditional channels, can explain part of this expansion as the process of economic growth gives rise to capital deepening in the economy even when the food share of total expenditures declines. In this case, the lack of complete markets and policy distortions can further exacerbate the effects of supermarkets on the traditional marketing system and the small farmers that it supports. The article proceeds by describing the conceptual framework of a Ramsey growth model to fit on data of the Moroccan economy. The empirical results show how capital deepening in transition growth can encourage the expansion of the supermarket system without the need to appeal to economies of scale or imperfect competition. The article concludes by noting how economic policy and other market imperfections can affect this process.

This article analyzes the role of foreign direct investment (FDI) and trade in promoting economic growth across selected developing countries and examines the interaction among FDI, trade, and economic growth. Data from 66 developing countries are examined. Results of the study suggest that FDI, trade, human capital, and domestic investment are important sources of economic growth for developing countries. It is discovered that there is a strong positive interaction between FDI and trade in advancing economic growth. Results also show that FDI stimulates domestic investment. The contribution of FDI to economic growth is enhanced by its positive interaction with human capital and sound macroeconomic policies and institutional stability. With the results, there is an implication that lowering the inflation rate, tax burden, and government consumption would advance economic growth in developing countries.
