Agricultural and Trade Policy Reform and Inequality: The Distributive Effects of Direct Payments to German Farmers under the EU's New Common Agricultural Policy AgEcon
von Witzke, Harald; Noleppa, Steffen.
The Common Agricultural Policy (CAP) of the European Union has been in a process of reform since the early 1990s. As a result of reforms, agricultural market regulations have become more liberal and direct payments have been introduced which are to a large extent decoupled from production. In this paper, we analyze the effects of the direct payments to farmers on inequality of profits in German agriculture. For this purpose, we decompose measures of absolute and relative inequality in total farm profits into the partial effects of the direct payments and all other profit determinants. Key results of the analysis are that the system of direct payments under the New CAP accounts for about one third of the observed inequality in family farms and for almost...

AGRICULTURAL POLICY PREFERENCES: WHEAT IN THE UNITED STATES, 1981-1990 AgEcon
Oskam, Arie J.; von Witzke, Harald.
This paper outlines DEBET (Decision Based Economic Theory), a method for determining revealed preferences of governments. DEBET is applied to US wheat policy decisions in the 1980s. This method has a number of advantages over alternative approaches to the analysis of revealed preferences of government. It makes use of information contained in policy alternatives contemplated but not agreed upon, and it is suitable for modeling the discrete - continuous choice problem of policy makers in a multi-instrument context.

Decoupled Payments to EU Farmers, Production, and Trade: An Economic Analysis for Germany AgEcon
von Witzke, Harald; Noleppa, Steffen; Schwarz, Gerald.
After an extended process of reform the European Union has introduced direct payments to farmers which are decoupled from production decisions as a central element of its Common Agricultural Policy. They are also referred to as Single Farm Payments. In this paper we analyze the production and trade effects of this policy and its compatibility with WTO international trade rules. A survey of the literature suggests that the system of direct payments in its present form has effects which are analogous to a subsidization of agricultural land. Thus, they act to increase production and trade. Furthermore we quantify the total economic cost of production of selected commodities in the European Union and compare them to the price at which EU production is sold in...

Determinants of the U.S. Wheat Producer Support Price: A Time Series Analysis AgEcon
von Witzke, Harald.
Public choice in agriculture is an emerging field in agricultural economic research. The paper's focus is on the determinants of the U.S. wheat producer support price. The econometric time-series analysis suggests that this price is largely determined by the previous price, the expected U.S. share in world exports, and expected program costs. Presidential elections also influence U.S. wheat price policies. All other things being equal, the support price tends to be lower in election years than in other years. This suggests that small interest groups' relative political economic power may be smaller in election years if they do not succeed in positioning themselves on the political economic market such that they contain the potentially decisive voter.

Determinants of Wages and Returns to Education in Rural India AgEcon
Subbaraman, Subhashini; von Witzke, Harald.
This study focuses on estimating determinants of wages across primary, secondary and tertiary sectors in rural India by the type of work contract involved. Casual labourers, with short term work contracts and nearly absent benefits and wage employees, with long term work contracts, higher wages and benefits represent dual sections of the labour market. Here we demonstrate that human capital and other factors that has been proven to explain variation in wages in other labour markets, explain little about wages in casual employment sector. Further, pattern of returns to education for casual labourers were found to decrease with increasing educational levels and was negative for higher education. Such a trend was no t noticed among wage employees, where...

ECONOMIC REFORMS IN POLAND: IMPLICATIONS FOR AGRICULTURE AgEcon
Hausner, Ulrich; Cichon, Janusz; von Witzke, Harald.
Throughout the world, agriculture has become integrated into the economy at large. Therefore, it is not possible to analyze the process of economic and political transformation of agriculture without reference to the general thrust and speed of reform (Pasour, 1992). In this paper, we will argue that Poland, like other countries in Central and Eastern Europe, faces a dilemma of economic and political reform. Further, we will discuss some of the central variables which tend to constrain the process of economic transition and recovery. Following we will first discuss some of the central effects of partial and stepwise economic reform. Second, we will analyze the pros and cons of economic shock therapy, i.e., of a rapid switch to a market...

Global agricultural market trends and their impacts on European Union agriculture AgEcon
von Witzke, Harald; Noleppa, Steffen; Schwarz, Gerald.
The economic, political and climatic conditions in which farmers around the world have to make their production and investment decisions are changing dramatically. This study analyses the driving forces of changes in agricultural world markets and their implications for European Union agriculture for the time period 2003/05 - 2013/15. The impacts on European Union agriculture are quantified using of a multi-market-model. The mega-trend of declining world market prices has ended. Since the turn of the millennium world market prices for agricultural goods have been increasing. This trend can be expected to continue. Not only will prices have a tendency to increase, but also fluctuations of agricultural world market prices are likely to be higher in the...

Landwirtschaft in der okologischen Marktwirtschaft: Sicherung der Welternahrung vs. Klimaschutz und Bioenergie AgEcon
von Witzke, Harald.
Ökologie und Klimaschutz sind in aller Munde. Die politischen Parteien in Deutschland und anderswo sind sich weitgehend einig. Die Marktwirtschaft soll "„ökologisch"“ sein. Für Ökonomen ist dies Problem zumindest theoretisch ziemlich trivial. Die Emission von Klimagasen ist eine negative Externalität und Klimaschutz ein öffentliches Gut. Beides sind Formen von sog. Marktversagen. Staatliche Aktivität hat dann das Potential, das Marktergebnis aus gesamtwirtschaftlicher Sicht noch zu verbessern. In jeder Einführungsveranstaltung zu den Grundlagen der Wirtschaftswissenschaften werden den Studierenden die Charakteristika von Externalitäten und öffentlichen Gütern beigebracht und auch die gesamtwirtschaftlich effizienten staatlichen Aktionen bei Auftreten von...

Social rate of return to plant breeding research in Germany AgEcon
von Witzke, Harald; Jechlitschka, Kurt; Kirschke, Dieter; Lotze-Campen, Hermann; Noleppa, Steffen.
This article focuses on the social rate of return to plant breeding investment in Germany between 1980-2000. Starting point of the analysis is the development of total factor productivity which is decomposed into the effects of factor input and research investment. Information on investment in plant breeding have been obtained via questionnaires sent to both private plant breeding companies and public research organizations. The empirical results suggest significant underinvestment in German plant breeding research, as the calculated social rate of return is in the range of 16 to 28%.
