| This paper examines volatility transmission in oil, ethanol and corn prices in the United States between 1997 and 2011. We follow a multivariate GARCH approach to evaluate the level of interdependence and the dynamics of volatility across these markets. Preliminary results indicate a higher interaction between ethanol and corn markets in recent years, particularly after 2006. We only observe, however, significant volatility spillovers from corn to ethanol prices but not the converse. We also do not find major cross-volatility effects from oil to corn markets. The results do not provide evidence of volatility in energy markets stimulating price volatility in grain markets. |

| In order to stimulate organic farming governments generally use a mix of temporary hectare payments and provision of public services for stimulating the development of the organic sector. In this paper a conceptual model is developed for determining a socially optimal hectare payment for any given level of public services. Farm heterogeneity, due to the variability of soil quality and management skills, is explicitly taken into account. Using an n-th price auction mechanism farmers indicate what their reservation subsidy is for a given level of public input provision. The outcome of this problem is utilized in the government's optimization problem. We found that the level of per hectare socially optimal subsidy increases significantly with the elasticity... |

| Different views exist on the future development of organic agriculture. The Dutch government believes that in 2010 10% of the farm land will be used for organic farming. Others have a more radical view: due to increasing emphasis on sustainable production in the end all farming will be organic. Others believe in a more pessimistic scenario in which the recent growth in organic was just a temporary upswing and that the share of organic farmers already reached its maximum. In this paper different potential scenarios for the further growth of organic farming are evaluated using Bayesian techniques. A nonlinear logistic growth model explaining the share of organic farms is estimated using available historical data for Dutch agriculture. Various scenarios imply... |

| Rain-fall shortage constrains production in small-holder agriculture in developing countries and with ongoing climate change these shortages may increase. Rain-water harvesting are interesting technologies that decrease this risk. Therefore, one would expect an increasing use of these technologies in drought-prone areas. However, data collected in Ethiopia shows that the share of irrigated land in total landholding declines with farm size. This study investigates why the share declines with farm size using panel data collected in 2005 and in 2010. A random-effect tobit model is estimated for the share of irrigated land as a function of variables affecting returns, market prices, source of finance and expectation formation. The findings show farm-specific... |

| This paper investigates borrowing decisions of rural households from a microfinance in Tigray, Ethiopia using household panel data on 5 years and a dynamic panel probit model. The theoretical model takes two types of risk involved in joint-liability lending explicitly into account: risk of partner failure and the risk of losing future access to credit. Empirical results show that these risks are important in explaining borrowing decisions. Another finding is that the probability of repeat-borrowing is higher than the probability of new participation, with possible implications that perceived joint-liability threats deter participation and easing stringent punishments might help poor households’ access to credit. |

| Agricultural land markets differ greatly from the textbook-case of perfect competition. This is why standard hedonic pricing techniques should be revised before applying this technique to this market. The objective of this paper is to determine (a) the deviation from the competitive market price of agricultural land in the Netherlands due to market power and the existence of an excess surplus and (b) the effect of bargaining power on the division of excess surplus between the eventual seller and the buyer in the market for agricultural land. |
