The planning of mechanization requires the quantitative assessment of a mechanization index and the impact of this index on agricultural yield and economic factors. The purpose of this paper is to investigate the effect of the adoption of agricultural mechanization and scale production on labour...

Since the early 1990s, liberalization of the seed market in Tanzania has attracted several foreign companies that now market maize hybrids in the country. In this article, we analyze the impacts of proprietary hybrids on maize yields, production, and household living standards. We build on a...

Using household survey data from Ethiopia, this paper evaluates the impact of agricultural cooperatives on smallholders' technical efficiency. We utilize propensity score matching to compare the average difference in technical efficiency between cooperative farmers and similar independent...

What patterns can be discerned in the distribution of farm sizes across countries and over time? How does the behavior of individual economic agents interact with the natural environment and general economic development to affect farm size? How has concerted human intervention, understood as...

Small farms are the largest employment and small business group among the poor. Their businesses use mostly labor and local resources and face local constraints, but at the same time, they are affected by increasingly complex national and global economic changes, which lead to shifts in...

This paper shows that using yields may not be informative of the relationship between farm size and productivity in the context of small-scale farming. This occurs because, in addition to productivity, yields pick up size-dependent market distortions and decreasing returns to scale. As a result,...

This study assessed the determinants of intensity of adoption of Improved Rice Varieties (IRVs) and the effect of market participation on farmers' welfare in Nigeria using the Tobit and Heckman two-stage models, respectively. The sample consists of crosssectional data of 600 rice farmers...

This paper presents the impact evaluation of CRIAR program, implemented in rural areas in Bolivia. The objective of CRIAR is to increase smallholders' agricultural income and food security through productivity improvements triggered by technological adoption. In this study, we use data from a...

Do transgenic crops cause agrobiodiversity erosion? We hypothesize that they increase productivity and reduce production risk and may therefore reduce farmer demand for on-farm varietal diversity, especially when only a few transgenic varieties are available. We also hypothesize that varietal...
