Cournot markets in the field: Dynamic decision- making in non-standard markets
Lara-Arango, David; Gerber, Andreas; Nyanga, Progress; Kopainsky, Birgit (Conference object; Peer reviewed, 2017)The Cournot economic model is very useful for representing atomized markets in laboratory experiments. Ideally, such experiments are designed following a set of conditions in order to use the model properly. However, ... -
The Dynamics of Food Availability in sub-Saharan Africa: An Endogenous Perspective on Food Production Systems
Gerber, Andreas (Doctoral thesis, 2017-11-18)Food insecurity is a major challenge of our time: In 2015, 795 million people suffered from hunger worldwide. The eradication of hunger remains a target of high-level policy programs such as the United Nations’ Sustainable ... -
How do Zambian smallholder farmers allocate their budget? Evidence of dynamic decision-making based on a Cournot field experiment
Gerber, Andreas; Lara-Arango, David; Nyanga, Progress; Kopainsky, Birgit (Conference object; Peer reviewed, 2017)Smallholder farmers in sub-Saharan Africa repeatedly face situations of complex and dynamic decision trade-offs, which include allocating money across short-term and long-term production activities. Short-term activities ... -
Short-Term Success versus Long-Term Failure: A Simulation-Based Approach for Understanding the Potential of Zambia’s Fertilizer Subsidy Program in Enhancing Maize Availability
Gerber, Andreas (Peer reviewed; Journal article, 2016-11-19)In Sub-Saharan Africa, food-related policies such as fertilizer subsidy programs (FSPs) have undergone a revival and triggered a controversy about their impact. In this article I applied a simulation-based approach to ... -
Short-term versus long-term decision trade-offs: Evidence from a model-based observational experiment with African small-scale farmers
Kopainsky, Birgit; Gerber, Andreas; Lara Arango, David; Nyanga, Progress Hanzwida (Peer reviewed; Journal article, 2019)Smallholder farmers in sub‐Saharan Africa recurrently face situations of complex and dynamic decision trade‐offs. Short‐term‐oriented activities such as fertilizer application help to cover immediate food needs but compromise ... -
Why do some food availability policies fail? A simulation approach to understanding food production systems in south-east Africa
Gerber, Andreas (Peer reviewed; Journal article, 2017-07-20)Food production systems in south-east Africa face a persistent puzzle: despite the implementation of numerous plausible food availability policies, the region’s history is characterised by many cases of food production ...
