Evaluating Different Growth Scenarios for Organic Farming Using Bayesian Techniques AgEcon
Gardebroek, Cornelis.
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...

Farm Size and the Share of Irrigated Land in total Landholding: the case of Water-Harvesting Irrigation in Ethiopia AgEcon
Wakeyo, Mekonnen B.; Gardebroek, Cornelis.
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...

Bargaining and market power in a GIS-based hedonic pricing model of the agricultural land market AgEcon
Cotteleer, Geerte; Gardebroek, Cornelis.
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.

Some like to join, others to deliver. An econometric analysis of farmers' relationships with agricultural co-operatives AgEcon
Pascucci, Stefano; Gardebroek, Cornelis.
In many European countries, farmers are a member of a processing or marketing co-operative, and most of these farmers also deliver their products to that co-operative. However, an extensive dataset of Italian farmers shows that not all members deliver to their co-op, and that there are also non-members that deliver. Using theoretical arguments from the New Institutional Economics literature, a bivariate probit model is estimated to explain co-op membership and delivery jointly. Results show that membership and delivering are indeed related, but also that different factors influence farmers’ decisions on membership and delivery.

Farm-Specific Factors Affecting the Choice Between Conventional and Organic Dairy Farming AgEcon
Gardebroek, Cornelis.
Organic dairy farming in the Netherlands is a growing sector. This paper investigates the impact of a number of economic and farm-specific variables on the choice between conventional and organic farming. Based on expected utility maximisation, a theoretical framework is developed that explicitly accounts for the impact of non-economics variables like age and education level and unobserved characteristics. The model is estimated with an unbalanced panel of Dutch dairy farms using a random effects probit specification.

Does microfinance reduce rural poverty? Evidence based on household panel data from northern Ethiopia AgEcon
Berhane, Guush; Gardebroek, Cornelis.
This paper evaluates the long-term impact of microfinance credit from the intensity of participation in borrowing. We use a four-round panel data set on 351 farm households that had access to microfinance in northern Ethiopia. Over the years 1997-2006, with three-year intervals, households are observed on key poverty indicators: improvements in annual consumption and housing improvements. The relatively long duration in the panel enables to measure household poverty changes between consecutive periods and see the long-run effects of exposure to microfinance from the intensity of participation borrowing. The fixed-effects model is innovatively modeled to account for potential selection biases due to both time-invariant and time-varying unobserved individual...

THE IMPACT OF MANURE PRODUCTION RIGHTS ON CAPITAL INVESTMENT IN THE DUTCH PIG SECTOR AgEcon
Gardebroek, Cornelis.
In this paper the effect of manure production rights on investment decisions of Dutch pig farmers is examined. A dynamic optimization model of investment that explicitly takes zero investments into account is augmented by a constraint on production arising from the introduction of manure production rights. In the theoretical model it is shown that such a constraint has a reducing effect on investment. The presence of this constraint is tested for using GMM structural break tests. The results provide evidence for the hypothesis that manure production rights have reduced investments through its effect on production.

Growth Dynamics of Dairy Processing Firms in the European Union AgEcon
Gardebroek, Cornelis; Turi, Kedir N.; Wijnands, Jo H.M..
The structure of the dairy processing industry in the European Union has changed enormously in recent decades. In many countries the industry is characterized by a few large companies with a big market share accompanied by many small processors that often produce for niche markets. This paper investigates which factors relate to growth of dairy processing firms. Using a unique ten-year panel data set and recently developed dynamic panel data estimators, the growth process of dairy processors is investigated for six rather diverse European countries. The data structure and the estimation method allow for dealing with endogeneity issues in an appropriate way. Firm size growth measured in total assets is found to be affected by firm size, firm age and...

Stimulating Organic Farming Via Public Services and an Auction-Based Subsidy AgEcon
Feinerman, Eli; Gardebroek, Cornelis.
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...

Joint-liability borrowing decisions under risk: Empirical evidence from rural microfinance in Ethiopia AgEcon
Berhane Tesfay, G.; Gardebroek, Cornelis.
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.

Do energy prices stimulate food price volatility? Examining volatility transmission between US oil, ethanol and corn markets AgEcon
Gardebroek, Cornelis; Hernandez, Manuel A..
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.

DYNAMIC MICROECONOMETRIC APPROACHES TO ANALYSING AGRICULTURAL POLICY AgEcon
Gardebroek, Cornelis; Oude Lansink, Alfons G.J.M..
Micro-econometric models have become a standard and powerful tool in analysing agricultural policies. In this paper we assess the contributions that have been made in the agricultural economics literature to dynamic microeconometric models of firms and households that are estimated using microdata. After discussing developments in dynamic investment models, dynamic household models, dynamic discrete choice models and dynamic efficiency models we give promising directions for future research and discuss implications for future data collection.
