| This paper utilizes cointegration theory, error correcting model and Granger causality testing theory to make an empirical research on the relation between urbanization and GDP in China, and also implements a comparative analysis to the relation between three industries and degree of urbanization, the related coeffecient is 0.97, 0.95, 0.97, 0.97. And the result shows a long-term balance between these two factors, and the promoting effect to tertiary industry by urbanization is more obvious. Urbanization and economic growth are the long-term balanced relations. In the long-term balance, every 1% increment of urbanization can make 4.82% increment of GDP; In short-term balance, if the balance depart from the long-term balance at the i-th term, the model will... |

| According to the data from Investigation Report of Land Use Change in China, The Land Resources Communique of China and Chronicle of Statistical Data for Five Decades of New China issued from Ministry of Land Resources, we select two indices: change of farmland quantity and policy of farmland protection. According to econometric theory, by using Eviewes 5.1 software, co-integration analysis, Granger causality test, impulse response and other analysis methods, we analyze the relationship between change of farmland quantity and policy of farmland protection in China since the reform and opening-up. The results show that there is long-term balanced relationship between change of farmland quantity and policy of farmland protection, and there is a certain... |

| This paper examines the cross-impacts of food safety news concerning one product on the demand for another product, using the Danish demand for pasteurized eggs versus shell eggs as an illustrative case. The study identifies news with a temporary impact and news with a permanent impact on consumers' food demand behavior. The techniques used to identify the permanent versus temporary news are recursive estimation and parameter stability. Whereas "permanent" news is identified to be represented by a specific individual event, "temporary" news concerning salmonella in eggs is aggregated into a news-index variable. Both temporary and permanent news concerning salmonella in shell eggs appear to have significant positive impacts on the demand for pasteurized... |

| This paper presents an investigation into the market structure for three product types of salmon (smoked, fresh and whole salmon) in the UK retail market. Evidence of the potential for market power and pricing conduct is analysed using structural simultaneous system equations based on the Bresnahan (1982) model. The importance of the retail market is recognised given the dominance of supermarket chains which accounted for £1.6 billion sales of seafood and the share of about 87% of all seafood retail sales in 2004 as compared with only 16% in 1988. The results indicate that the system is well represented by the models and that the market is competitive for fresh fillets and whole salmon but retailers exert some market power for smoked salmon. The hypothesis... |

| A significant increase of concentration in the UK salmon retail subsector has heightened concerns about retail firms’ ability to exercise market power in the purchase of supplies (oligopsony power). To assess the extent to which retail firms have exercised oligopsony power, we develop a dynamic error correction translog profit function to model the behaviour of retailers in the input market for smoke, fillet and whole salmon. Initial estimates indicated violations of monotonicity and convexity conditions as implied by economic theory. In order to ameliorate the problem, a Bayesian technique was used to impose inequality restrictions to correct the anomaly. The final estimated indices of market power in the models were low and statistically significant but... |

| This paper examines the cointegration of grain market prices in Northern Ethiopia. Results are based on bi-monthly retail price data on wheat and teff collected from six markets in the Tigray region of Northern Ethiopia. The data has 55 observations for each of the two crops in each of the six markets ranging over a period of May 2006 to October 2008. Johansen’s cointegration test reveals that most markets are cointegrated in wheat and teff retail prices. There is an indication that retail prices at Abi-Adi, a town located relatively farther away from the main asphalt road, is less integrated to other markets. This implies that infrastructural development is crucial for spatial market integration through market information transmission and physical... |

| This paper examines the price discovery function for three U.S. wheat futures markets: the Chicago Board of Trade, Kansas City Board of Trade, and Minneapolis Grain Exchange. The maintained hypothesis is that futures markets search more for information than cash markets to find an equilibrium price, thus greatly improving the price discovery function. The tests reveal the existence of one equilibrium price across the three futures markets in the long run, but no cointegration among prices in the three representative cash markets. |

| By using error correction model, I conduct co-integration analysis on the research of the relationship between the per capita practical consumption and per capita practical disposable income of urban residents in Hunan Province from 1978 to 2009. The results show that there is a co-integration relationship between the per capita practical consumption and the practical per capita disposable income of urban residents, and based on these, the corresponding error correction model is established. Finally, corresponding countermeasures and suggestions are put forward as follows: broaden the income channel of urban residents; create goods consuming environment; perfect socialist security system. |

| The objective of this study was to determine whether long-run relationships existed between price premiums for wools with different fibre diameters. Based on cointegration analysis using monthly data from 1976.8 to 1999.10, the results showed that price premiums, in relative price terms, for fibre diameters between 19 and 23 micron were cointegrated. Furthermore, the price premiums for 19, 20 and 21 micron were found to be weakly exogenous. The latter result suggested that price premiums for finer wools tended to be more stable, compared with coarser wools which appeared to bear the burden of price adjustments. The implication is that wool producers would enjoy more stable prices, and hence income, by focusing on finer wools. |
