We present a dynamic two-region model with overlapping generations. There are two types of productive public expenditure, education and infrastructure funding, and governments decide optimally on budget size (tax rate) and its allocation across the two outlays. Productivity of government infrastructure spending can differ across regions. This assumption follows well established empirical eviden...

BACKGROUND AND OBJECTIVES Diabetes affects approximately 1 million South Africans. Hospital admissions, the largest single item of diabetes expenditure, are often precipitated by hyperglycaemic emergencies. A recent survey of a 200- bed hospital, serving approximately 1.3 million Cape Town residents, showed that hyperglycaemic emergencies comprised 25.6% of high-care unit admissions. A study wa...

The impact of aid inflows on relative prices and output is ambiguous. Aid inflows that increase domestic expenditure are likely to cause real exchange rate appreciation, ceteris paribus. However, if this expenditure raises the capital stock in the traded goods sector, then output in this sector might not contract, at least in the steady state. Moreover, if investment in the nontraded goods sect...

Small cells technology has also strong potentials for enhancing cell coverage and network capacity of next-generation cellular networks including 5G. From mobile network operators’ perspective, small cell deployment will additionally achieve large reduction to the network costs in both fields of capital expenditure and operational expenditure. In this study, we analyze the benefits of small cel...

Background The escalating cost of pharmaceuticals is a global challenge and major hindrance to access to medicines in developing countries. Half of the Ugandan population lacks reliable access to essential medicines and out of pocket expenditure by patients is as high as 80% [1]. Generic medicines provide an opportunity for savings on medicine expenditure due to their cheaper price [2,3]. Gener...

The Cloud Computing concept offers dynamically scalable resources provisioned as a service over the Internet. Economic benefits are the main driver for the Cloud, since it promises the reduction of capital expenditure and operational expenditure. In order for this to become reality, however, there are still some challenges to be solved. Amongst these are security and trust issues, since the use...

Household survey data from the Kyrgyz Republic are used to analyse changes in the determinants of household expenditure during the transition from central planning. Quantile regression is applied to a human capital model with consumption related to the household head’s education and controlled for demographic and locational variables. Education, region, ethnicity and family size are all signifi...
