This paper uses a stochastic frontier and inefficiency model to test the efficiency of grape production in the Western Cape. The data covers two panels of wine grape farms (34 in Robertson and 36 in Worcester) for 2003 and 2004 and 37 table grape farms in De Doorns for 2004 only. Tests show that...

This paper fits a translog stochastic production frontier with inefficiency effects to a panel of 693 UK dairy farms for the period from 1982 to 1997. The Cobb Douglas is rejected as inadequate relative to the less restrictive translog functional form and the frontier model is statistically...

An error correction model (ECM) of induced innovation, based on the two-stage CES production function allows direct tests of the inducement hypothesis, which are applied to U.S. data for 1880–1990. The time series properties of the variables include a structural break in 1920, cointegration is...

Analysis of a survey of the 1998-99 and 1999-2000 seasons for the same 100 smallholders in the Makhathini Flats region of KwaZulu-Natal shows that Bt cotton has performed better than other varieties. Having two years of data for the same farmers allows innate efficiency differences, due to...

Intellectual property protection, globalization, and pressure on public budgets in many industrialized countries have shifted the balance of plant breeding activity from the public to the private sector. Several economic factors influence the relative shares of public versus private sector plant...

This paper models dairy farms in KwaZulu-Natal, South Africa, emphasising the complexities unique to this multi-product industry. Net and gross output approaches to measuring production are discussed and then tested using panel data from 37 dairy farms in KwaZulu-Natal from 1999 and 2007....

This paper focuses on assessing the benefits of research expenditures on maize production in South Africa. Both the production and supply function approaches are used to calculate elasticities of research expenditure on output and yield. Cointegration is used to establish long-run relationships...

This paper uses non-parametric approach to measure technical innovation and productivity growth at the smallholder farm-level in dry-land sub-Saharan Africa during the initial years of the structural adjustment programmes for agriculture. Data from Kenya for two production years, 1991/2 and...

The paper presents an empirical investigation of the production response of small scale producers of maize and cotton for communal agriculture in Zimbabwe. The error correction model, which employs the concept of cointegration to avoid spurious regressions, is used in the analysis. The factors...
