| In this paper we investigate the role of poultry in the livelihoods portfolios of households and the impact of supply and demand shocks that may be caused by Highly Pathogenic Avian Influenza (HPAI) on various livelihoods outcomes of households in four Sub-Saharan African (SSA) countries. The study countries include Ethiopia and Kenya in East Africa and Ghana and Nigeria in West Africa. These countries represent a spectrum of SSA countries in terms of disease status, role of poultry sector and means of disease spread. By using nationally representative household level secondary data and discrete choice methods (probit model and zero inflated negative binomial model) we profile the household, farm and regional characteristics of those households who are... |

| Reliable marketing opportunities in both interregional and international trade are an important precondition for further development of the agricultural sector. In this study we assess interregional integration of Kazakh wheat markets. We apply asymmetric threshold error correction models to assess the co-movement of elevator prices at three grain-trading spots in the northern and central parts of the country. Results suggest that markets of two northern grain-trading spots (Petropavlovsk and Kokshetau) are closely connected with each other while their connection with Karaganda in central Kazakhstan is much weaker. Here, levelling out price gaps through arbitrage trade only occurs after a threshold of considerable extent has been surpassed. |

| Reliable marketing opportunities in both interregional and international trade along with relatively low transportation [and transaction] costs are essential to profitability of wheat production. In this study we have investigated one aspect of the quality of marketing and trade opportunities in the Kazakh wheat sector, that is the extent and nature of integration among regional wheat markets. We applied threshold cointegration technique to assess the co-movement between time series of elevator prices at three grain-trading (and producing) spots in the northern and central parts of the country. Results suggest that markets of two northern grain trading spots (Petropavlovsk and Kokshetau) are closely connected with each other while their connection with... |
