| Until now empirical analyses have not succeeded in the determination of a general upon agreed bunch of the most important driving forces of structural change in agriculture beyond the level of the national economy. It will be argued that the sometimes contradictory results of different studies are caused by the endogenous dynamics of structural change as well as by mixing up different levels of causality. The influence of single causes, therefore, is not necessarily characterised by linearity, symmetry and independence of other causes, of the location or of time. Multi-level-models are being presented as a method with the capability to cope with these problems by modelling hierarchical relations and dynamics in time simultaneously. The flexibility of the... |

| This paper provides an overview of grain transportation policy in Canada over the last 100 years, including the inception of the Crow Rate, the replacement of the Crow Rate with the Western Grain Transportation Act(WGTA), and finally, the repeal of the WGTA. Particular emphasis is placed on the structural change to the western agricultural economy that occurred following repeal of the WGTA in 1995. When grain transportation subsidies were removed, industry responded quickly to market signals through a diversification of crop patterns, an increase in livestock production, and an increase in value-added processing. Key Words: transportation policy, diversification, structural change |

| Rapid change in the size and ownership structure of U.S. hog production has created new and varied challenges for the industry. This report describes an industry becoming increasingly concentrated among fewer and larger farms, and becoming more economically efficient. These changes have not come without problems. The increasing market control and power concentrated among packers and large hog operations, and the manure management problem posed by an increasing concentration of hog manure on fewer operations, are paramount concerns. Addressing these concerns through regulations would likely impose economic costs that could be passed on to consumers. In addition, the relative mobility of the hog industry means that regulations could result in significant... |

| The dominant pattern in U.S. non-alcoholic drink: consumption over the past 25 years has been a steady increase in per capita soft-drink: consumption, largely at the expense of coffee (and to a lesser extent) milk consumption. Our findings suggest that the major factor governing this pattern is structural change. Specifically, trend was found to be statistically significant in three of the four equations estimated in the Rotterdam system. Moreover, the estimated trend-related changes in per capita consumption (-1.0 percent per year for milk, 2. 1 percent for soft drinks, and 3.7 percent for coffee and tea) leave at most 28 percent ofthe observed quantity variation for 1990-1994 to be accounted for by changes in relative prices, income, and advertising.... |

| An inverse live-hog model was estimated to analyze whether there has been a recent increase in the magnitude of live-hog, own-quantity demand flexibility. Estimating the impact of processing capacity-utilization rate changes on live-hog prices was a second objective of this research. Results indicate that live hog prices have become more responsive to changes in hog slaughter, slaughter weight, cold storage stocks, and changes in the processing capacity-utilization rate. Finally, model results indicate that the sharp increase in processing capacity-utilization rates, the increase in average dressed weight, and the increase in hog slaughter all had a negative effect on the live-hog prices. |

| Recent trends in mergers and acquisitions in the U.S. food sector food manufacturers, wholesalers, and retailers raise concerns about market power. In the presence of market power, farmers may receive lower than competitive farm prices, and consumers may pay higher than competitive retail prices. This study presents empirical tests of market power at the national level for seven food categories: beef, pork, poultry, eggs, dairy, fresh fruit, and fresh vegetables. At the national level, our tests provide evidence of competitive conduct in both the sale of final food products and the purchase of farm ingredients. |

| We use newly nonparametric volatility measures and break techniques to estimate common breaks across grain futures over the recent ten years. Our results show one structural change in realized volatilities occurred in 2006 for corn and in 2007 for soybean. But the date difference between them cannot be negligible. We disaggregate the realized volatilities into a continuous component and a jump part and found the source of structural beak in realized volatilities is from jumps. |

| This paper explains regionally differentiated patterns of structural change based on a theoretical framework dealing with strategic interaction of farms on the land market. The main research question focuses on the causes of regionally persistent structures. An empirical Markov chain model is defined for the West German agricultural sector. Thereby it is possible to explain the probabilities of farm growth, decline or exit in terms of the current and former regional farm size structure. Further, the impact of variables describing the regional farm structure, thereby indicating market power of the large, the potential of high competition for land within a region and possibly high rents of the status quo in combination with sunk costs, is quantified. The... |
