Participatory policy evaluation as an innovative method to improve processes of sustainable rural development AgEcon
Bocher, Michael.
This paper presents an innovative process-orientated self-evaluation method regarding sustainable rural development processes, developed by the University of Göttingen in cooperation with rural actors and a consultant. This method, which is also available online, can be employed by rural development initiatives in order to manage their own work successfully. The paper presents the general evaluation research design and the computer-based method for the self-evaluation of regional development initiatives. It also discuses the potential problems of such a participatory research design which emerged through important empirical findings

Spatial R&D Spillovers and Economic Growth - Evidence from West Germany AgEcon
Funke, Michael; Niebuhr, Annekatrin.
The paper bases itself on recent theoretical writings in growth economics that emphasize the effects of both own R&D efforts and of interregional technology spillovers on regions´ productivity. We propose robust estimation techniques to evaluate the R&D spillovers across West German functional regions during the period 1976 - 1996. The findings suggest the existence of knowledge spillovers across functional regional boundaries. Moreover, significant spillovers are mainly found among geographically close regions. This finding confirms the hypothesis that proximity matters. Das Papier basiert auf jüngeren Beiträgen zur Wachstumstheorie, die den Stellenwert eigener F&E-Anstrengungen und interregionaler Spillover-Effekte für die regionale...

Threshold Effects and Regional Economic Growth - Evidence from West Germany AgEcon
Funke, Michael; Niebuhr, Annekatrin.
We study an overlapping generations model of human capital accumulation with threshold effects using regional data for West Germany. Our basic goal is to shed light on the growth of West German regions. The paper finds that the relative income distribution appears to be stratifying into a trimodal distribution. Thus, application of the threshold model to a real world case, here West Germany, shows that the model might help to explain regional growth patterns. Ausgangspunkt der Analyse ist ein Modell überlappender Generationen der Humankapitalakkumulation mit Schwellenwert-Effekten. Die empirische Überprüfung des Modells basiert auf einem regionalen Datensatz für Westdeutschland. Das zentrale Ziel der Untersuchung ist es, Erkenntnisse zum Wachstum...

Farm Structural Change in German Regions - An Empirical Analysis using Micro and Macro Data AgEcon
Zimmermann, Andrea; Heckelei, Thomas.
General economic developments as well as recent fundamental changes in the Common Agricultural Policy will likely impact significantly on the European farm structure. Although a decline of total farm numbers continues to be the general observation, important differences occur across regions and farm types. These differentiated developments and their determinants are of high relevance for policy impact assessment at the regional level. The main objective of the analysis provided in this paper is to empirically identify whether regionally specific characteristics account for differences in regional farm structure development. This is exemplarily shown for German FADN regions. As methodological approach a combined time series, cross-sectional Markov chain...

The Emerging Role of E-Agribusiness - State of the Art and Perspectives in Germany AgEcon
Doluschitz, Reiner; Emmel, Markus; Kaiser, Fabian; Pape, Jens; Roth, Michael.
The aim of this paper is to describe and analyse the emerging role of electronic agribusiness and the corresponding consequences in Germany. The study was carried out as a consecutive step by step procedure, including empirical surveys in farm and agribusiness small and medium size enterprises, accompanied by case studies in agribusiness firms, and a technology assessment expert survey. The results indicate that internet penetration on farm and agribusiness enterprise levels is rather high, but currently information and communication activities clearly dominate over commercial business activities. The case studies show that the internal communication changed significantly due to the implementation of internet applications like emailing, newsgroups,...

The Transformation of the Agricultural Administration in East Germany Before and After Unification AgEcon
Wolz, Axel.
With the collapse of the socialist regime in East Germany in late 1989 and the rising political call for unification in early 1990, a deep change of the institutional structure became necessary. The (agricultural) administration had to be totally restructured. This referred not only to substance, functions and tasks which had to be adjusted – similar to all other transition economies - to the market-economic and pluralistic democratic system, but also the whole administrative set-up had to be re-established in line with the West German system. Hence, a new administrative system had to be built up from scratch in the East, while the socialist one had to be dismantled in a short period. Overall, this institutional change seems to have been accomplished...

Why do Farmers Spend Different Amounts of Transaction Costs in Agri-Environmental Schemes? AgEcon
Weber, Anja Michaela.
Agri-environmental schemes provide payments for farmers in return for environmental services. Implementation induces transaction costs (TCs). Borne by farmers (private TCs), their amount may inhibit participation. Research shows substantial variances in private TCs within single schemes, which are largely unexplained to date. Furthermore, no distinction has yet been made in research whether farmers spent TCs due to scheme-prescribed tasks, or voluntarily to achieve "transaction gains.‟ This might be an important factor in farmers‟ perceptions of TCs. The overall aim of this analysis is to explain within-scheme TC variances. TCs are defined functionally as “costs of participation.” The variance in TC spending is assumed to represent a different willingness...

Concentration and Specialisation Trends in Germany since Reunification AgEcon
Suedekum, Jens.
In this paper we describe the development of regional specialisation and geographical concentration in Germany between 1993 and 2001. Somewhat contrary to theoretical expectations derived from the recent literature in location theory, we neither find compelling evidence for a specialisation process of German regions, nor for a concentration process of industries. By and large and with some exceptions, this conclusion holds both for West Germany and Germany as a whole, as well as for all levels of territorial aggregation (NUTS1-NUTS3). Urban areas are stronger specialised than rural districts, but also subject to faster de-specialisation. Those regions, which have increased regional specialisation against the trend, have performed significantly better in...

Transaction costs in agri-environmental schemes: the principal-agent-point of view AgEcon
Weber, Anja Michaela; Nuppenau, Ernst-August.
Agri-environmental schemes provide payments for farmers in return for environmental services. Their implementation induces transaction costs for administration and farmers. Although transaction costs became subject of research in recent years, little attention has been paid to activities which create them. This paper uses insights from Principal-Agent-Theory to show, how information gaps between contracting partners result in tradeoffs inducing activities conducted at implementation level. A Grassland Extensification Scheme, provided in Hesse, Germany, serves as a case-study. The paper shows that attempts and incentives to overcome informational gaps are different for administration and farmer. Further, attempts to reduce transaction costs of own...

REMIND-D: A Hybrid Energy-Economy Model of Germany AgEcon
Schmid, Eva; Knopf, Brigitte; Bauer, Nico.
This paper presents a detailed documentation of the hybrid energy-economy model REMIND-D. REMIND-D is a Ramsey-type growth model for Germany that integrates a detailed bottom-up energy system module, coupled by a hard link. The model provides a quantitative framework for analyzing long-term domestic CO2 emission reduction scenarios. Due to its hybrid nature, REMIND-D facilitates an integrated analysis of the interplay between technological mitigation options in the different sectors of the energy system as well as overall macroeconomic dynamics. REMIND-D is an intertemporal optimization model, featuring optimal annual mitigation effort and technology deployment as a model output. In order to provide transparency on model assumptions, this paper gives an...

Elastizitäten der Nachfrage privater Haushalte nach Nahrungsmitteln – Schätzung eines AIDS auf Basis der Einkommens- und Verbrauchsstichprobe 2003 AgEcon
Thiele, Silke.
This paper presents price and income elasticities of food demand in Germany. Using cross sectional data from the 2003 German income and consumption survey a Linear Approximate Almost Ideal Demand System is employed. Two aspects which have to be taken into account when using cross-sectional data are insufficient price information and zero expenditures. An approach of COX and WOHLGENANT (1986) is applied to derive quality adjusted prices. In order to take into account censoring of the dependent variables a procedure of SHONKWILER and YEN (1999) was employed. A high expenditure elasticity is found for meat demand. The highest own-price elasticities are for the demand for meat/-products and milk/-products. Within the meat group, beef demand shows a particular...

Income Diversification of Farm Households: Relevance and Determinants in Germany AgEcon
Pieniadz, Agata; Renner, Swetlana; Rathmann, Christoph; Glauben, Thomas; Loy, Jens-Peter.
During recent years, the number of farms able to generate satisfactory income from agricultural production has continuously decreased in advanced economies. The main reasons are the implementation of the Common Agricultural Policy of 1992 and the increasing capitalization of the primary sector. The relevance of income diversification and interest in various development paths of rural households have, therefore, been renewed in political-economic debates in those countries. The aim of this study is to identify factors that determine income diversification in Germany. An econometric model has been estimated based on a comprehensive survey’s data. The results show that the main economic incentive for farm diversification is the expected income increase or...

Locating Foreign Affiliates in Germany: The Case of Swedish MNEs AgEcon
Braconier, Henrik; Ekholm, Karolina.
This paper uses a dataset on the foreign activities by Swedish manufacturing firms to examine the performance of German affiliates compared with affiliates in other locations. It is found that German affiliates, on average, have higher labour productivity, R&D expenditure per employee and skill-intensity. There is also evidence suggesting that German affiliates are more oriented towards selling in the local market than affiliates in other European countries. We also analyse the effect of labour costs in the Swedish multinational enterprises' (MNEs') decision to locate in Germany. We find that the location decision is sensitive to the level of wage costs in Germany and in other potential locations in high-income Europe, but not to the level of wage...

The Taste for Variety: A Hedonic Analysis AgEcon
Drescher, Larissa S.; Thiele, Silke; Weiss, Christoph R..
Based on the model of consumers' variety-seeking behavior introduced by Anderson et al. (1992), this paper derives a hedonic price function for a households' consumption bundle. The price a consumer pays for her consumption bundle reflects the values of the underlying attributes of goods purchased but also accounts for any preference for variety that she might have. The empirical analysis is conducted for 3,240 German households and their expenditure on 182 different soft drinks over a six-month period. We find that consumers have a preference for variety in food consumption, ceteris paribus. Furthermore, the per-unit price is found to be significantly larger for higher income households, as well as households where the principal wage earner has a high...

The Fertility Transition in Bavaria AgEcon
Brown, John C.; Guinnane, Timothy W..
The decline of human fertility that occurred in Europe and North America in the nineteenth century, and elsewhere in the twentieth century, remains a topic of debate largely because there is no accepted explanation for the event. Disagreement persists in part because researchers have rarely used the detailed quantitative information necessary to form adequate tests of alternative theories. This paper uses district-level data from Bavaria to study the correlates of the decline of fertility in that German kingdom in the nineteenth century. Bavaria’s fertility transition was later and less dramatic than in other parts of Germany. The European Fertility Project, the most influential study of the European fertility transition, used very large units of analysis...

Farm Structure and the Effects of Agri-Environmental Programs: Results from a Matching Analysis for European Countries AgEcon
Pufahl, Andrea; Weiss, Christoph R..
This paper extends previous research (Pufahl and Weiss, 2009) and applies a semi-parametric propensity score matching approach to evaluate the effects of agrienvironment (AE) programs on input use and farm output of individual farms in eight Member States of the European Union. We find substantial differences in treatment effects between countries. The analysis reveals significant effects of AE participation on production (Germany, France) and farm profits (France, Ireland, United Kingdom). AE participation sporadically reduces the intensity of land use as measured by the purchase of farm chemicals (fertilizer, pesticide) and grazing livestock densities. We also find differences in the treatment effect among farms with different farm size (heterogeneous...

Optimal Grain Marketing Revisited: A German and Polish Perspective AgEcon
Loy, Jens-Peter; Pieniadz, Agata.
Increasing grain price volatility over the last year has revived the discussion on optimal marketing strategies. Various models of optimal grain marketing have been proposed and simulated in the literature. In this study an overview on these models is presented and critical aspects are discussed. Optimal strategies are then applied to the wheat market in Germany and Poland. Results indicate that gains from optimal marketing are rather small and uncertain in the real world, indicating that scientific assistance might be of limited importance. However, an understanding of optimization and price generating processes is likely to improve farmers’ decisions, e.g. if farmers have additional (private) information to improve price forecasts.
