Tracing Uganda’s global primary organic pineapple value chain

The organic sector is one of the fastest growing sectors globally. The sector provides an opportunity for developing countries to export high value products in the global market. One such opportunity for Uganda is the export of organic pineapples. The organic pineapple enterprise is relatively new, having existed for approximately 10 years. This paper traces the organic pineapple value chain, characterises and explains the functions of the actors in the chain. The study used the Global Value Chain Analysis Framework, using data obtained from 140 organic farmers, 10 exporters and 3 support institutions in Uganda. It is clear from the study that the chain is private- sector-driven, has relatively young smallholder farmers, and comprises of 10 small scale export companies. Only 45% of the organic pineapples produced by farmers reach the organic consumers. Reasons for this included limited processing capacity of exporters, competition from conventional buyers and the few local organic consumers. Other reasons were declining soil fertility, limited regulative institutional support and poor infrastructure. We recommend increased use of soil amendments, favourable legislations and investment environment, increased horizontal coordination among exporters and increasing the range of the organic export products in order to increase organic pineapple sales.Keywords: Certification, organic consumer value strea

Backward bending structure of Phillips Curve in Japan, France, Turkey and the U.S.A.

This work aims to analyse the cointegration and the causality relationship between inflation and unemployment by using nonlinear A.R.D.L. and two popular nonlinear causality tests for the period from 1960 to 2016 in Japan, Turkey, the U.S.A. and from 1970 to 2016 in France. This study complements the previous empirical papers. However, it differs from the existing literature with simultaneous use of nonlinear A.R.D.L. and causality methods. Nonlinear A.R.D.L. determined that there is a long run relationship between inflation and unemployment; between economic growth and unemployment for Japan, France, the U.S.A. and Turkey

A chain oligopoly model of merger strategies and competition

Competition along an agri-food chain is analysed with the use of a chain oligopoly model. This model includes an oligopoly facing an oligopsony, which are solved simultaneously. The results of standard industrial organization models are altered when oligopoly-oligopsony is modelled simultaneously. Verifying the countervailing power hypothesis, it is shown that it is not always profitable to exercise market power when there are firms with market power on the other side of the market. It is also shown that there are more powerful incentives for vertical than horizontal mergers in the case of chain oligopolies. The merger between MD FOODS and KLØVER MAELK in Denmark highlights several of the issues involved
