Transaction costs play a key role in the behaviour of smallholders in developing countries. We investigate smallholder tobacco cultivation in Malawi, Malawi's major export crop, and exploit the introduction of an additional tobacco auction floor to measure the impact of a reduction in...

I use the quasi experimental nature of the roll-out of the mobile phone network in Mozambique to estimate the impact of search costs on the dispersion of maize prices and transport costs. The introduction of mobile phone services from 1997 to 2009 explains a 4.5-11% percent reduction in price...

We investigate to what extent the roll-out of the mobile phone network in Mozambique reduced transport costs and search costs, and thereby decreased spatial price dispersion and improved market efficiency. Estimations are based on data of transport costs of maize grain and maize market prices....

We estimate to what extent bridges in Mozambique lead to transport cost reductions and attribute these reductions to key determinants, in particular road distance, road quality and crossing borders. For identification we exploit the introduction of a road bridge over the Zambezi river, in August...

Prior to 2009, there was no direct road connection between the southern regions of Mozambique - where the capital city is located - and the more agriculturally-productive central and northern regions. In this paper, we leverage the opening of a major road bridge to identify the impact of...

We measure the impact of search costs on farmers' and traders' transaction prices in Mozambique by investigating to what extent the introduction of mobile phones has affected the margin between recorded maize producer and retail market prices, and by exploring if producers or traders benefit...

Risks management studies in the agri-food sector predominately focus on the technical methods and the capability to perceive, prevent, mitigate, and recover from diverse risks. In most economic publications the risks are usually studied as other commodity regulated by the market supply and...

Empirical studies on efficiency of the governance system in agriculture are very rare. That is a consequence of both theoretical and practical challenges. The criteria and approach for assessing social efficiency are still debated while appropriate statistical, accountancy, etc. data for...
