702 Time Series Analysis of Wheat flour Price Shocks in Pakistan: A Case Analysis Asad Raza Abdi Assistant Professor; Department of Economics, Shah Abdul Latif University, Khairpur Mirs, Pakistan Ali Hassan Halepoto Assistant Professor; Department of Commerce, Shah Abdul Latif University, Khairpur Mirs, Pakistan Aisha Bashir Shah Assistant Professor; IBA, University of Sindh, Pakistan Faiz M. Shaikh Assistant Professor; SZABAC, Dokri, Larkana, Pakistan Abstract The current research investigates the wheat flour Price Shocks in Pakistan: A case analysis. Data was collected by using secondary sources by using Time series Analysis, and data were analyzed by using SPSS-20 version. It was revealed that the price of wheat flour increases from last four decades, and trend of price shocks shows that due to certain market variation and supply and demand shocks also play a positive relationship in price shocks in the wheat prices. It was further revealed that Government should take certain measures to Stable prices of wheat in Pakistan. Keywords: Time series, price, shocks, wheat Introduction 1 The agriculture sector continues to be an essential component of Pakistan’s economy. It currently contributes 21 percent to GDP Agriculture generates productive employment opportunities for 45 percent of the country’s labour force and 60 percent of the rural population depends upon this sector for its livelihood. It has a vital role in ensuring food security, generating overall economic growth, reducing poverty and the transforming towards industrialization. The present government is determined to improve the quality of life of the people and to banish hunger and malnutrition from the country by making agriculture an efficient, productive and profitable sector of the economy. 1 Corresponding author’s details: Name: Faiz M.Shaikh Email address: faizanmy2000@hotmail.com In order to improve governance in the public sector the government took bold steps and brought in the 18 th Amendment to the Constitution of 1973. Accordingly, Ministr ies performing tasks which were provincial subjects were devolved from the Federal level, including the Ministry of Food and Agriculture. However, realizing the food security concerns across the country the government took timely steps to establish the Ministry of National Food Security and Research to tackle the Food Security issues. The newly created Ministry, under the aegis of the present government, has planned to take two major steps in order to solve the food security issues on a permanent basis. The first step is the establishment of the National Food Security Council Federal, Province local level Governments. Secondly, through a Letter of Intent the Ministry, in collaboration with World Food Program, is launching the Zero Hunger Program worth US $ 1.6 billion to address the Asian Journal of Agriculture and Rural Development journal homepage: http://aessweb.com/journal-detail.php?id=5005 mailto:faizanmy2000@hotmail.com Asian Journal of Agriculture and Rural Development, 3(10) 2013: 702-708 703 food security objective. Under this Program the Ministry shall donate up to 500,000 metric tons of wheat per year and the World Food Program intends to negotiate with local producers to exchange part of the donated wheat for High Energy Biscuits (HEB) and similar products manufactured in Pakistan factories for distributions through WFP operations to primary school children, siblings of malnourished children and the vulnerable populations especially children at risk of malnutrition. The fund wil l a l so be converted to fortified wheat flour for distributions aimed at combating food insecurity in Pakistan. The W F P wi l l a l s o c o o p e r a t e in t h e c a p a c i t y WFP building of the Ministry’s officials in areas addressing food security and monitoring progress. In Pakistan, wheat being the staple diet is the most important crop and cultivated on the largest acreages in almost every part of the country. It contributes 14.4 percent to the value added in agriculture and 3.0 percent to GDP. Over the past three decades, increased agricultural productivity occurred largely due to the deployment of high-yielding cultivars and increased fertilizer use. With the introduction of semi-dwarf wheat cultivars, wheat productivity has been increased in all the major cropping systems representing the diverse and varying agro-ecological conditions. Wheat in Pakistan Pakistan has been divided into ten production zones because of great agro ecological areas where wheat is grown. The zoning is mainly based on cropping pattern, disease prevalence and climatological factors. However, production zones need to be revisited. In Pakistan, wheat is grown in different cropping systems, such as; cotton - wheat, rice - wheat, sugarcane - wheat, maize - wheat, fallow - wheat. Of these, Cotton-Wheat and Rice-Wheat systems together account about 60% of the total wheat area whereas rain-fed wheat covers more than 1.50 m ha area. Rotations with Maize- Sugarcane, Pulses and fallow are also important. Improved semi-dwarf wheat cultivars available in Pakistan have genetic yield potential of 6-8 t/ ha whereas our national average yields are about 2.7 t/ha. A large number of experiment stations and on-farm demonstrations have repeatedly shown high yield potential of the varieties. There are progressive farmers of irrigated area who are harvesting 6 to 7 tones yield per hectare. However, farmers yield ranges 0.5 to 1.3 tons per hectare depending on the amount of rainfall in rained areas and in irrigated areas it ranges from 2.5 to 3 tons per hectare depending upon the amount of water available and other factors.

There was huge difference year to year from 1961-2012. The Wheat flour price trend was found to be increasing trend. There was price shocked in the years 1955, 188, 2000.2007 where nearly 70- 80% prices were changed.

One way to analyze these beverages would be to postulate that they form a block independent group and then use demand equation. One disadvantage of this approach is that equation group the nose demand equation. One disadvantage of this approach is that equation involves real income and. through their influence on the Frisch price index log P, the price of other (i.e. non-Wheat) goods. Conditional demand equations deal only with Wheat and thus avoid he problem. Accordingly a system with a large number of commodities can be transformed into a number of smaller. Independent sub systems, one for each group of goods. In this section, we set out detail of this approach Recall from the retail price. Due to unstable prices of Wheat consumers are paying more every month. The recent price shocks have a negative impact on the consumers.

It has direct relationship with the demand of the market and supply shortage from time to time increased the prices of wheat in Pakistan. In Pakistan have genetic yield potential of 6-8 t/ ha whereas our national average yields are about 2.7 t/ha. A large number of experiment stations and on-farm demonstrations have repeatedly shown high yield potential of the varieties. There are progressive farmers of irrigated area who are harvesting 6 to 7 tonnes yield per hectare. However, farmers yield ranges 0.5 to 1.3 tons per hectare depending on the amount of rainfall in rain fed areas and in irrigated areas it ranges from 2.5 to 3 tons per hectare depending upon the amount of water available and other factors. Conclusion The current research explores the wheat prices shocks and wheat flour prices in Pakistan. The results of the analysis indicate that wheat growers are response to changes in the wheat of wheat in the case of production and acreage under wheat response. The lagged wheat of cotton has no significant impact on the production of wheat and acreage under wheat. This may attributed to the reason that cotton is grown on marginal lands and usually in the western areas of Pakistan. The cultivation of cotton is also risky due to the attack of pests. Government of Pakistan should fixed the price of the Wheat and also take some measures to control the prices of Wheat. References Cocharne, W. W. (1995).
