The effect of agricultural policy change on income risk in Swiss agriculture AgEcon
El Benni, Nadja; Finger, Robert; Mann, Stefan.
The study examines the effect of agricultural policy reforms on income variability of Swiss farmers. The observed heterogeneity in income risks across farms and time is explained with farm and regional characteristics. FADN data are used to construct coefficients of variation of total household income and gross revenues at farm-level over the period 1992-2009. Applying linear mixed effect models the effects of off-farm income, direct payments, farm size, specialisation and liquidity on gross revenue and household income variability in three different production regions are measured. The switch from market-based support to direct payments decreased the variability of farm revenues and household income. Off-farm income has a positive and farm size a negative...

Trade Restrictions on Farmland - a Utilitarian Analysis of Paternalistic Laws AgEcon
Mann, Stefan.
The aim of this paper is to approach the normative analysis of paternalistic laws. Our examples are restrictions on trade in agricultural land: a quantitative restriction in Switzerland and Germany and a fixed price range for lease land in France. We develop a normative framework from the literature and apply it to the restrictions. It shows that the quantitative restrictions apparently rest on a misunderstanding of structural change and can therefore hardly be justified, whereas the price allegation protects from information asymmetries which would lead to unfair results. Hence it can be shown that a normative analysis of paternalistic interventions can produce meaningful results.

Können Produktionsentscheidungen als Investitionsentscheidungen modelliert werden? AgEcon
Mann, Stefan; Mack, Gabriele; Ferjani, Ali.
Interviews with Swiss farmers lead to the hypotheses that production decisions, also in crop growing, are not made annually, but similarly to investment decisions in the long run. This hypothesis is backed by non-parametric time-series analysis for Switzerland and Germany. This creates a theoretical basis for combining Positive Mathematical Programming with flexibility constraints in optimization models. Results of the forecasting model SILAS show that forecasting quality is improved through this approach.

Distributional effects of direct payments in Switzerland AgEcon
El Benni, Nadja; Mann, Stefan; Lehmann, Bernard.
The switch from market-support to direct payments in Switzerland had impacts on the income distribution among farmers. In this paper, the distributional effect of the switch as a whole and of the different kinds of direct payments are elaborated through a presentation of different decomposed Gini coefficients. Although the income distribution in Swiss Agriculture is still more equal than in most other countries, the Gini coefficient has risen from 0.27 in 1990 to 0.38 in 2009 and is by now strongly dependent on the composition of direct payments. Off-farm income and direct payments decrease, while market income increases income inequality.

Deliberation, Responsivity and Power in German and Swiss Agricultural Policy AgEcon
Mann, Stefan.
Preferences with respect to agricultural policy have changed in Germany and Switzerland. In the middle of the 20th century, food self sufficiency and a certain cultural solidarity with farmers were central issues. Today, farmers are expected to contribute to environmental protection and safe food. Switzerland and Germany are two examples of countries where national agricultural policies have attempted to take the changing preferences into account. However, in Germany the government had a hard time succeeding since the general features of agricultural policy are decided by the EU. Comparing Germany with Switzerland indicates that it might be more appropriate to decide on agricultural policy on the national rather than on a regional or supranational level.

The Depopulation of Rural Areas and the Farming System AgEcon
Mann, Stefan.
Depopulation of rural areas can entail negative externalities. This paper examines, inter alia, the influence of the farming system on depopulation processes. The population change in rural communities in Switzerland (family-based farming system) and in the German Land Mecklenburg-Western Pomerania (fordistic farming system) is explained through regression analysis by the proportion of persons occupied in the three economic sectors and by other variables. In Switzerland, a high proportion of locals occupied in farming affects population dynamics positively; in Mecklenburg- Western Pomerania, the situation is exactly opposite. This can serve as an argument to support small and networked farms in rural problem regions.

Farm Entry Policy and Its Impact on Structural Change Analysed by and Agent-based Sector Model AgEcon
Mack, Gabriele; Mohring, Anke; Zimmermann, Albert; Gennaio, Maria-Pia; Mann, Stefan; Ferjani, Ali.
The Swiss agent-based model (SWISSland) claims to depict as realistically as possible the 50 000 family farms comprising the whole of Swiss agriculture in all their heterogeneity as regards farm and cost structures as well as farm decision-making behaviour and interactions, with the aim of improving the simulation and forecasting of structural change in agriculture. With the linking of different methods and recorded data, there is a marked increase in the quality of the assessment of policy consequences. Simulations are shown for policy measures which affect only farm entry by cutting socially motivated direct payments for young operators.

Modelling structural change in the agricultural sector – An Agent-based approach using FADN data from individual farms AgEcon
Mohring, Anke; Zimmermann, Albert; Mack, Gabriele; Mann, Stefan; Ferjani, Ali; Gennaio, Maria-Pia.
The development of multi-agent models for agriculture has allowed the inclusion of farm decision-making behaviour and interactions in the simulation of smaller agricultural regions. Important methodological impact for this has come in particular from scientists from Germany. Currently under construction, the SWISSland model claims to depict as realistically as possible the 50,000 family farms comprising the whole of Swiss agriculture in all their heterogeneity as regards farm and cost structures as well as farm decision behaviours, with the aim of improving the simulation and forecasting of structural change. This paper describes methodological aspects in the formation of the agent population by combining various data sources such as accounting and spatial...

Framing Obesity in Economic Theory and Policy AgEcon
Mann, Stefan.
While obesity is a growing problem that entails considerable costs, its causes for individuals are not yet well understood in economic terms. Three explanatory approaches are explored: obesity as a rational decision pursued by the individual, obesity as a problem of too little information and obesity as the result of a weak will. While the recent rise in obesity can be explained rationally by a changed environment, information deficiencies and akrasia contribute to explaining its frequency. If the state intervenes, a fat tax carries much higher allocative losses than taxing overweight directly.

Theorie und Empirie agrarstrukturellen Wandels? AgEcon
Mann, Stefan.
The paper examines to which extent the theory of the farm household and the argument of path dependencies can be confirmed through recent empirical contributions on structural change in agriculture. In addition, a model is developed that explains structural change through occupational choices in favour or against farming. The validity of this model is challenged by empirical results, too. It can be shown that all three theoretical approaches contribute to explaining structural change in agriculture, which results to a coexistence of small and large farms if not hampered by political interference.

Die Expertenbewertung als Alternative zur Kontingenzbewertung AgEcon
Mann, Stefan.
A lot of research is carried out on the Contingent Valuation Method to assess environmental goods. However, the method is rarely applied to quantify reimbursements for agri-environmental policy. In this paper, this contradiction is explained by conceptual shortcomings of the Contingent Valuation. It is suggested to discuss the utility of agri-environmental programs among experts. For that, a three-step methodology including a possible monetary evaluation is developed. The method is applied on agri-environmental programs in Switzerland.

Zur Effizienz der deutschen Agrarverwaltung AgEcon
Mann, Stefan.
The efficiency of agricultural administration is analysed in this article by costs that arise in a region for administring one hectare farmland or one farm. Variances of these costs between regions can be explained by intra-organisational efficiency on the one hand and by inter-organisational efficiency on the other. Costs for the administration of 131 German regions are empirically estimated. Costs per hectare vary between DM 44 and DM 183. By regression, cost variances can be explained by the area a regional office administers and by the participation of a district office in the system, two important inter-organisational factors. A comparison of services between “cheap” and “expensive” regions does not reveal clear differences.

Trends in family labour, hired labour and contract work on French and Swiss crop farms: The role of agricultural policies AgEcon
Dupraz, Pierre; Latruffe, Laure; Mann, Stefan.
The objective of this article is to analyse the trends in on-farm labour use, including own family labour, hired labour and contract work, and to assess the factors driving their evolution in France and in Switzerland during 1990-2007. A particular attention is given to agricultural policies, namely the level and type of support. Results indicate that crop area payments discourage the different labour demands in both countries, while environment and investment payments favour contract and hired labour in France. Contract labour and family labour are substitute and hired labour and family labour are complement in France.

Defining elasticities for PMP models by estimating marginal cost functions based on FADN Data - the case of Swiss dairy production AgEcon
Mack, Gabriele; Mann, Stefan.
The Swiss agricultural sectoral information and forecasting system (SILAS) is based on the PMP standard approach. The marginal cost functions are estimated by exogenous elasticities. Due to the lack of empirical data the elasticities were set for all activities to unity. Based on total milk production costs of FADN farms, regional supply functions were estimated. The results are used to adjust the marginal cost functions of organic and non-organic dairy cow activities in the model SILAS to the empirically estimated functions. The results show that the marginal cost functions in the sectoral model are in general a bit steeper than in the FADN estimations, when elasticities by the value one are applied. Major differences between organic and non-organic milk...

The Nature of the Diversified Farm Household AgEcon
Mann, Stefan.
This paper presents a theoretical approach that explains farm household diversification decisions by the relative attractiveness of both food production and family businesses. The empirical analysis of diversified activities of Swiss farm households shows that a low household income leads to diversification by off-farm activities, while a high income leads to diversification by on-farm activities. It is also shown that arable farms, mountain farms and farm households with a non-agricultural education are more likely to enter off-farm activities.

Population development in rural Switzerland: Do sectors matter? AgEcon
Mann, Stefan.
The paper approaches the question of the role of the three different sectors in rural population development. A regression with data from 1606 rural Swiss municipalities shows that activity in the farming sector enhances population growth to a greater degree than activity in the industrial sector. Employment in the service sector was not found to sustain population growth in rural municipalities, whereas commuting possibilities had a strongly stabilising impact. Other important determinants were wealth, the number of holiday homes and demographic factors. A qualitative study of four rural municipalities largely confirmed the findings of the regression, but also showed the importance of non-economic factors influencing the relative attractiveness of a rural...
