Mangoes are one of Pakistan's most important fruits; the country is the world's fourth largest producer and exporter of mangoes. Integrated markets are those where price signals are transferred from one to another, allowing physical arbitrage to adjust any disturbances in these markets; integrated markets are thus a sign of efficiency. From this viewpoint, we investigate domestic integration among ten major mango markets, i.e., Lahore, Faisalabad, Multan, Gujranwala, Sargodha, Karachi, Hyderabad, Sukkur, Peshawar, and Quetta employing Johansen's cointegration approach and error correction model. Data on monthly wholesale prices data (PRs/100 kg) were obtained from the agricultural and livestock marketing advisor, Government of Pakistan. The results of the study confirm the presence of integration among major mango markets in Pakistan. These markets were able to adjust for 16 to 68% of disequilibrium in one month, implying that it takes almost two to six months to remove any disequilibrium and to move back to long-run equilibrium. The Granger causality test shows that the Karachi market has bidirectional causality with Lahore, Faisalabad, Multan, Hyderabad, and Sukkur, and a unidirectional relationship with the rest. An impulse response analysis was also conducted to check the stability of these markets given a standard error shock to the Karachi base market. JEL Classification: A10, C01.

This paper attempts to evaluate the impact of monetary and macroeconomic factors on real wheat prices in Pakistan for the period 1976-2010, using Johansen's co-integration approach. The Augmented Dickey-Fuller test reveals that all the variables used are first-difference stationary, except the trade openness indicator, which is second-difference stationary. There is also a longrun equilibrium relationship among these variables. The results indicate that real money supply, openness of the economy, and the real exchange rate have a significant effect on real wheat prices in the long run. The impulse response function shows that a trade openness shock impacted wheat prices to some extent and that it took three to four years for prices to become stable, following the shock. The findings of the study suggest that the policy thrust should focus on increasing wheat supply in the country by enhancing production or by liberalizing trade. Efforts should also be directed toward stabilizing the value of the Pakistani rupee against foreign currencies, especially the US dollar.

This paper analyzes the impact of major factors on the export of mangoes from Pakistan. We use a cointegration approach and error correction mechanism applied to data for the period 1970–2005. Mango exports are regressed against the index of relative prices of mango exports (2000 = 100), the quantity of domestic mango production, real agricultural gross domestic product (GDP), the length of all-weather roads, and international standardization, i.e., the impact of the World Trade Organization agreement. The results of the augmented Dickey-Fuller test reveal that all the data series are I(1). Applying Johansen’s test shows that the highest elasticity coefficients are found for mango production in the short and long run, followed by real agricultural GDP. The Granger causality test points to the bi-directional causality of mango exports with the relative price index and allweather roads, and unidirectional causality with real agricultural GDP and mango production. The study recommends promoting proper orchard management, developing the appropriate infrastructure, and stabilizing export prices to increase mango exports from Pakistan.
