This paper introduces the rank-based estimation method to modelling the Cobb-Douglas production function as an alternative to the least squares approach. The intent is to demonstrate how a nonparametric regression based ...

The power of the Granger and Lee (1989) model of asymmetry is examined via bootstrap simulation. The results of the bootstrap simulation indicate that the Granger and Lee model has low power in rejecting the null hypothesis ...

The Minimum Description Length (MDL), a less known criterion, is making great strides in model selection as compared to the widely known and used information criteria (AIC, BIC, etc). This study developed the MDL criterion ...

This study examines the effect of previous price and climatic variables on maize supply in Ghana. For this purpose, two separate approaches are used: (i) a lag model using the OLS technique and (ii) a quantile regression ...

Climate change tends to have negative effects on crop yield through its influence on crop production. Understanding the relationship between climatic variables, crop area and crop yield will facilitate development of ...

Land is an important asset that improves the livelihoods of poorer groups in every society, the world over but because of changes in some underlying factors, land is increasingly becoming a source of conflicts in Africa. ...

The study examined the outreach and sustainability of the inventory credit programme (ICP) in Ghana using both qualitative and quantitative data between 1996 and 2003. The findings revealed that the outreach of the ICP ...

Farm credit can stimulate the transfer of technology into agriculture and hence lead to increased crop yield. However, most often than not farmers are faced with the problem of loans received being far lower than what ...

A conventional approach to analysing asymmetric price transmission involves the use of the Houck’s static model. This paper compares this time invariant approach to a dynamic variant of the model. The static model is a ...

This study evaluates the performance of the recently developed model selection criteria (WIC) against commonly used alternatives (AIC and BIC) in terms of their ability to recover the true asymmetric data generating process. ...
