Social learning among Ghanaian cocoa farmers: Choosing the optimal amounts of inputs
Švenka, David ; Janský, Petr (advisor) ; Havránek, Tomáš (referee)
In this thesis I inspect learning about adoption of technologies among cocoa farmers in Ghana, which are represented by non-labor inputs, particularly by fertilizer and hybrid seeds. Earlier research focused mainly on learning about returns associated with adoption of such innovative inputs. However, it is not clear whether the adopters learn about these returns or rather about what are the optimal amounts of these inputs. Therefore the focus of this thesis is to examine how do the farmers choose and learn about optimal amounts of inputs. Cocoa farming is very labor intensive, and thus this thesis concentrates on learning about both non-labor and labor inputs, which are closely connected. Similar research carried out in India suggests that heterogeneous returns among farmers might cause that the farmers rely rather on their own considerations than on observation of behavior of their village neighbors, i.e. social learning. The heterogeneous returns are also present among the Ghanaian cocoa farmers, which suggest that these farmers should similarly prefer individual learning over the social one. Using a model developed for estimation of the prevailing type of learning about the optimal amount of inputs, I show that the farmers do tend to prefer individual learning in case of the non-labor inputs but rather...
Commercialization in Microfinance
Švenka, David ; Chytilová, Julie (advisor) ; Kracík, Jiří (referee)
This thesis is focused on commercialization in microfinance. Particularly on one of its possible negative impacts - the mission drift. Microfinance could be described as a useful financial tool that makes it possible to provide banking services, usually small loans and deposits, to rural poor people who live in places where it is hard to access the traditional banking sector. Commercialization of microfinance institutions means that the MFIs seek for commercial ways of funding. This usually happens when, for instance, some of the microfinance NGOs transforms into regulated commercial entity. Mission drift is then a situation when the microfinance institutions (MFIs) commercialize and abandon some of their poorest clients in order to pursuit some non-social goal such as sustainability or profitability. Therefore the MFIs drift from their original mission which is usually to fight the poverty. So far, there has not been conducted a lot of research on this topic. Furthermore, neither the microfinance experts agree with each other about the existence of mission drift. Therefore the main goal of this thesis is to closer inspect the mission drift on data from the MIX database. To do this we have used the regression analysis, combined with analysis of historical performance of the observed MFIs.
