The concept of a livelihood strategy has become central to development practice in recent years. Nonetheless, precise identification of livelihoods in quantitative data has remained methodologically elusive. This paper uses cluster analysis to operationalise the concept of livelihood strategies...

We investigate the interactions between natural resource-based poverty traps and food security for smallholder farms in highland Kenya using a recently developed system dynamics bio-economic model. This approach permits examination of the complex interactions and feedback between farm-household...

We investigate natural resource-based poverty traps using a system dynamics model of smallholder farms in highland Kenya. System dynamics modeling is well-suited to examining the complex interactions and feedback between farm-household economic decision making and long-term soil dynamics which...

We develop a simple theoretical model of market participation over multiple seasons in the presence of liquidity constraints and transactions costs to explain the 'sell low, buy high' puzzle wherein certain households forego opportunities for intertemporal price arbitrage through storage and are...

In this paper we investigate the possibility that price transmission between spatially distinct markets might vary during periods with and without physical trade flows. We are able to test for differences in price transmission between trade and non-trade regimes by using Generalized Reduced Rank...

In this paper we introduce a switching error correction model (SECM) estimator that allows for the possibility that price transmission between markets might vary during periods with and without physical trade flows. Applying this new approach to semi-weekly data on tomato markets in Zimbabwe, we...
