“…Brenton, Portugal‐Perez, and Regolo (2014) demonstrate that markets are more integrated within countries in Central and Eastern Africa. Similar results are reported in Southern Africa (Balchin, Edwards, & Sundaram, 2015; Nchake, Edwards, & Rankin, 2014); East Africa (Getnek, 2007) and West Africa (Oladapo & Momoh, 2008; Zakari, Ying, & Song, 2014). Nchake et al (2014), Balchin et al (2015), Brenton et al (2014), and Versailles (2012) report that members of the same regional trade agreements have substantially thinner borders with other members.…”

This paper examines-post-dollarization in Zimbabwe-the extent of price dispersion within Zimbabwe and between Zimbabwe and South Africa. We document the adjustment process, and the mechanisms of price adjustment after the introduction of the new currency system in Zimbabwe. We show that prices converged post-dollarization. We argue that the fall in price dispersion is not a product or a Southern Africa region effect. Rather it is a Zimbabwe specific effect and given that price convergence happens quicker the closer the month is to the dollarization, we argue that the observed results are driven by the change in currency. Price dispersion happens faster between major cities and secondary cities, suggesting improvements in information and trade signals between major and secondary cities. These results suggest that the positive effects of a stable currency fall disproportionally on secondary cities, implying price stability not only has macroeconomic benefits, but also developmental benefits since secondary cities and rural areas are on average, poorer than main cities.

“…In the first stage, we check for nonstationary or existence of unit root in the time series data. Due to the argument Zakari et al, [31], for the test to be accurate, the time series analysis must have the same order of integration. Augmented Dickey-Fuller (ADF) tests of unit root were used.…”

Afghanistan is overwhelmed with food insecurity that is a large percentage of the population lacks reliable access to food supplies. Grains play a vital role in the country's food security due to their importance in terms of consumption and production quantity. This paper estimates cereal self-sufficiency and then makes a food balance forecast of the three major food crops cultivated in Afghanistan over six-decades. Descriptive statistics and coarse metric techniques were employed to determine cereal self-sufficiency and food balance forecast. The econometric analysis demonstrated that (1) Afghanistan is not yet self-sufficient in meeting grain consumption, and the production and consumption ratio declined from 0.9 to 0.55 from 1979 to 2030. (2) The gap of theoretical food imbalance will increase, and by the year 2030, cereal production will likely be sufficient for only 49.8 percentage of inhabitants, leaving a high shortage equivalent to the amount required by 24.4 million people. By evaluating the quantitative food balance and the growing population change, this study presents an analysis of the emerging threat to Afghanistan's food security and suggests a solution for food security, should increase the size of public agricultural expenditure, improve the level of agriculture infrastructure, and continue to introduce a policy to achieve higher yield.

“…The model is widely used both to test the presence of price transmission asymmetry as well as to measure the degree of spatial integration of markets (Zakari et al, 2014). For the sake of brevity, we will not dwell much in discussing the structure of the model.…”

Price Transmission Asymmetry in Spatial Grain Markets in Ethiopia

Acknowledging the link between competitive and efficient spatial agricultural markets and farm productivity, the government of Ethiopia has implemented various market enhancing policy and institutional measures. The effectiveness of these measures to achieve their policy goals, among others, depends on the degree of symmetry prices transmit across spatial markets as well as on the efficiency of spatial arbitrage. We tested the presence of asymmetric price adjustment in the spatial grain markets in Ethiopia. The result provided clear evidence of asymmetric price adjustment for teff crops, but not for maize. For teff crops, prices adjust quickly to shocks that increase price than shocks that reduce prices. The analysis on the efficiency of the grain markets also showed that the spatial markets are characterized by a significant level of inefficiency. Although further research is necessary to establish the real causes for the observed asymmetric price transmission and market inefficiency, the finding suggests that departure from perfectly competitive settings are partly to be blamed for the recent food crops price hikes. In addition to their undesirable redistributional consequences, price transmissions asymmetry and inefficiency are expected to entail efficiency loss. Future empirical work in this area should strive to explain the underlying reasons for the observed asymmetric price transmission and market inefficiency.
