Determinants of tax revenue performance in the Southern African Development Community (SADC)

This paper investigates the determinants of tax revenue performance in all 15 Southern African Development Community countries during 1990-2010, using panel data. The investigation makes use of two estimation techniques in testing for country specificity. These are the least squares dummy variables fixed effects and the feasible generalised least squares by Park (1967) and Kmenta (1986). The extreme-bound analysis technique is also used in delineating the various causal relationships (including a sensitivity analysis).

Disentangling the exchange rate risk, sectoral export flows and financial development nexus

This paper examines the differential responses of various emerging market export sectors to exchange rate risk. This paper finds origin in initial theoretical posits of Ethier (1973) and Clark (1973) which both contend that exchange rate risk has a negative impact on the export flows of international trade participants who are assumed to be inherently risk averse.

The effect of tax harmonisation in the Southern African Development Community on Foreign Direct Investment

This paper investigates the effect of tax harmonisation on foreign direct investment (FDI) in the Southern African Development Community (SADC) region. Findings of a first attempt to investigate the linkage between taxation (tax rates and policy) and FDI (in all 15 countries), using an eclectic panel data modeling approach from 1990-2010 are presented.

Energy Consumption in South African Hotels: A Panel Data Analysis

Addressing the large energy consumption of hotels requires an understanding of the factors that drive this consumption. This enquiry is crucial for South Africa which has experienced significant strain in meeting its domestic energy demand. This has occurred alongside increases in international tourists, adding to the pressure on already strained resources. This paper tests hypotheses on drivers of energy consumption in hotels using a novel panel dataset which presents daily consumption data for 22 hotels across South Africa.

Non-Economic Quality of Life and Population Density in South Africa

The purpose of this study is to investigate the relationship between population density and non-economic quality of life. Popular opinion has generally been that population density can be seen as beneficial for economic growth, as it allows for greater productivity, greater incomes and can be translated into higher levels of quality of life. Recently though, growing evidence tends to suggest the exact opposite in that increases in productivity and incomes are not translated into better quality of life.
