| This study uses the inverse almost ideal demand system (IAIDS) to estimate demand flexibilities for beef, small ruminant (sheep and goat) meat, pork and poultry in Tanzania. Own uncompensated price flexibilities were less than one in absolute value, implying that both direct and indirect induced price effect through a change in total expenditure have little impact on budget shares. Estimated scale flexibilities were all negative, suggesting that increases in income will increase the quantities of meat consumed. Production of small ruminant meat was the most attractive investment compared to other meat commodities. |

| Based on China's Agricultural Regional Market Equilibrium Model (CARMEM), the paper projects the production and consumption of rice, wheat and maize in China toward 2010 at both national and regional level under two different scenarios. The results show that China can ensure a stable grain market development under more liberalized internal and external conditions. Transmission of the world market prices as projected by the World Bank (2003) to the Chinese domestic market would lead to a long-run recovery of the growth in grain production. Total production of paddy rice, wheat and maize is forecast to increase from 386 million tons in the base period 2002 to over 420 million tons in 2010. However, the rate of grain self-supply will be 91% due to higher... |

| In the context of a long run agricultural outlook on behalf of the European Environmental Agency a new methodology has been developed to systematically integrate external forecasts into a quite detailed agricultural sector model. External forecasts usually provide estimates for the exogenous variables in modelling work and frequently they are also used for comparisons and potential reassessment of empirical specifications. The innovative characteristic of this study is that expert forecasts have been used to specify parameter changes expressing structural change affecting behavioural functions. The outlook was therefore set up as a simultaneous estimation and forecasting effort which permitted to integrate various, usually contradictory expert forecasts... |

| This study examines retail fluid milk products purchase data from Nielsen 2005 home scan data. The demand for seven categories of fluid milk products were estimated: whole milk, whole flavored milk, reduced fat milk, flavored reduced fat milk, buttermilk, canned milk and all other fluid milk products. Analyses of the purchases of seven fluid milk categories based on the Nielsen 2005 home scan retail data are used to determine the roles marital status, age, race, education, female employment status and location play in the empirical estimations of aggregate demand elasticities. To derive the demand elasticities, a censored translog demand system is used. The results reveal that price and income are the main determinants of demand for fluid milk products... |

| A frequently encountered problem in import demand estimation is how to account for competition between imports and domestic production. Traditionally, use of the Armington model has been a way to handle this problem. This is a disaggregate model which distinguishes commodities by country of origin with import demand determined in a separable two-step procedure. The model appears frequently in analysis of international agricultural markets. However, the Armington model relies on a set of weak separability assumptions, which several authors have shown to be highly questionable. In this paper, a new aggregation theorem, the Generalized Composite Commodity Theorem (GCCT), is applied to test whether imports can be treated as a separate group. An advantage with... |

| The effects of various supply and demand shifts on beef price, quantity, and industry welfare have been widely studied under the assumption of beef quality homogeneity. In this paper, we construct a model of the beef sector that incorporates differences in beef quality. The model is used to analyze the effect of supply and demand shifts on changes in prices and quantities of high-and low-quality beef and changes in revenue accruing to producers of high-and low-quality beef. Model results indicate that supply and demand shocks have the potential to alter the average quality of beef on the market and the price premium charged for high-quality beef, which has important implications for retailers selling quality-differentiated beef and producers selling... |

| In this contribution, the development of price volatility on German agricultural markets is analyzed. We quantify the degree of price volatility for selected German agricultural markets and determine how it evolves over time and search for policy driven structural changes in volatility levels measured by the historical volatility. Based on annualised historical volatilities t test were performed to identify if the change in the volatility levels show any relationship to the process of reform of the CAP. An increase in volatility could be identified for the main German markets regulated by the Common Market Organisations. A positive relationship among the reform process of the CAP and the changes of the volatility levels could be identified particularly for... |

| It is commonly asserted that speculative buying by index funds in commodity futures and over–the–counter derivatives markets created a ‘‘bubble’’ in commodity prices, with the result that prices, and crude oil prices, in particular, far exceeded fundamental values at the peak. The purpose of this paper is to show that the bubble argument simply does not withstand close scrutiny. Four main points are explored. First, the arguments of bubble proponents are conceptually flawed and reflect fundamental and basic misunderstandings of how commodity futures markets actually work. Second, a number of facts about the situation in commodity markets are inconsistent with the existence of a substantial bubble in commodity prices. Third, available statistical evidence... |

| As events in the 2008/09 season have amply demonstrated, instability in staple food market remains a major problem in Zambia. A rise in world food price levels and instability, which is projected to occur in the near future according to several international institutes, will make it all more important for developing countries to consider the strengths and weaknesses of alternative approaches for buffering their domestic food systems from potential high volatility in world markets. These findings suggest that promoting more “rules based” approaches to... |
