The effect of internationalisation on the beef and maize sub-sectors: The relevance of revealed comparative advantage measures AgEcon
Jooste, Andre; Bahta, Sirak Teclemariam.
According to the RCA and RCA# the beef sub-sector in South Africa has shown a revealed comparative disadvantage for 17 out of the 22 years to 2002, while the maize sub-sector showed a revealed comparative advantage for 18 out of the same 22 years. However, this article argues that these results do not show the real state of competitiveness that exists in these sub-sectors, mainly because RCA measures should not be used to make definitive conclusions whether an industry, sector or sub-sector is competitive, nor whether it uses scare resources efficiently. RCA measures explain in more accurate ways, relative to a simple analysis of export trends, how a country features in the context of world trade. Hence, one possible application of RCA measures is to...

THE EFFECT OF THE SOUTH AFRICAN TRADE POLICY REGIME ON THE BEEF AND MAIZE SUB-SECTORS AgEcon
Bahta, Sirak Teclemariam.
Trade policies form the main economic 'buffer' between one national economy and another, i.e. the general and specific elements of each nation's trade policy interact directly or indirectly with those of other nations in all economic transactions across international borders. A nation's trade policy involves specific actions to encourage and promote or discourage foreign trade through the legal, financial and institutional environment within which foreign transactions occur. This study evaluates the trade policy applicable to the beef and maize sub-sectors in South Africa. Issues that are investigated include whether trade policy provides more or less protection than needed, whether it creates more openness for trade and the revealed comparative...

Estimation of Commodity Specific Production Costs Using German Farm Accountancy Data AgEcon
Bahta, Sirak Teclemariam; Berner, Anja; Offermann, Frank.
A central problem in estimating per unit costs of production originates from the fact that most farms produce multiple outputs and standard farm-accounting data are only available at the whole-farm level. The seemingly unrelated regression (SUR) approach is used to estimate per unit production costs based on German farm accountancy data. Special emphasis is put on outlier detection prior to the estimation of production costs to increase the robustness of the results. Outlier observations are identified based on the Mahalanobis distance for each observation on the data set. It was observed that less negative cost coefficients are estimated after the exclusion of the outliers. The time series analysis of cost estimation based on SUR regression shows the...
