Do microfinance institutions fulfil their promise? Evidence from cross-country data

The concept of microfinance promises poverty reduction and economic growth. We empirically challenge this economic and social promise in an attempt to prove its fulfilment. Our multivariate regressions of economic development variables such as per capita gross national income based on PPP converted to international dollars (GNI per capita PPP), GDP growth, as well as gross capital formation and labour participation rate against specific microfinance institutions’ (MFI) variables show that the success and performance of MFIs significantly influence economic development. Microfinance directly influences economic growth through the value that MFI performance adds to purchasing power. An indirect impact comes from an improvement in capital accumulation and employment rates. These insights are valuable as the interdependencies between microfinance and economic development that this article verifies offer new and progressive insights into purposeful action that can be taken to stimulate economic development and growth. Targeted development programmes as well as socially responsible investments can be applied in developing economies in order to strengthen their growth and alleviate poverty.     

Capital accumulation,income distribution and endogenous fertility in an overlapping generations general equilibrium model

A study is conducted in attempts to increase the understanding of the links between macroeconomic effects and causes of population growth in formulating policy. An overlapping generations general equilibrium model is employed aggregating household decisions about fertility, savings, and investment in the human capital of children with the objective of studying intertemporal relationships among population growth, income distribution, inter-generation social mobility, skill composition of the labor force, and household income. As a result of endogenous fertility, the equilibrium path attains steady state from the second generation. Income tax transfer, child taxation, and social security taxation policies are also examined in the paper. A structural explanation is given for the inverse household income-child quantity and negative child quality-quantity relationships seen in developing countries. In a Cobb-Douglas economy, these relationships hold in the short-run, potentially working over the long-run in other economies. Overall, the model shows that group interests may hinder emergence of perfect capital markets with private initiatives. Where developing countries are concerned, these results have strong implications for population policy. A policy mix of building good quality schools, or subsidizing rural education, introducing a formal social security program, and providing high-yield, risk-free investments, banking, and insurance services to the poor is recommended.     

Ecosystem Service Value and Agricultural Conversion in the Amazon: Implications for Policy Intervention

We explore the welfare implications of agricultural expansion in the Brazilian Amazon by comparing spatially explicit estimates of soybean rents and the value of ecosystem services. Although these estimates are generated from different datasets, models, and estimation techniques, the values are comparable, such that the value of ecosystem services is greater than soybean rents for about 61% of the total area and 24% of the area where soybean rents are positive if protected areas are well enforced. Based on the balance between the benefits and costs of conversion, failure to value ecosystem services reduces total social welfare by 7.13 billion dollars annually relative to an optimum. Policy instruments that internalize the value of ecosystem services via protected lands, land conversion taxes, conservation subsidies, or excise taxes can avoid much of this loss. Regardless of intervention regime, policy makers should be cognizant of the diminishing net benefits of converting natural ecosystems to agriculture. Realizing the final 3.8% requires the conversion of an additional 15% natural ecosystems to soybean production.
