This paper makes a contribution to the application of nonlinear simultaneous equations estimation and nonparametric Bootstrapping techniques. The nonlinear demand model estimation work in this paper is in the context of the newly developed Quadratic Almost Ideal Demand System (QUAIDS) model, and provides substantive results in terms of both model estimation technique and empirical economic findings. For the first time, bootstrapping is used in this highly nonlinear modeling environment to estimate variability in demand model parameter estimates and associated demand elasticities. The application relates to Japanese consumer behavior relative to Wagyu Beef, Imported Beef, Pork, Chicken, and Fish demand, and the empirical results are highly relevant to U.S.... |

Foreign direct investment (FDI) is known as a very relevant driver of economic growth and has found increased attention in recent trade research. Existing theories differ, however, in their conclusion regarding the relation between trade in goods and FDI: they appear to be either complements or substitutes depending on the theory applied and specific country conditions. Benefits or losses for individual member countries resulting from these different relationships are relevant for evaluating the effects of regional trade areas as established by the Euro-Mediterranean Partnership. This paper offers an empirical analysis of the connection between trade and FDI flows in the agribusiness sector in the context of the Euro-Mediterranean partnership. It... |

This paper presents an application of Bayesian analysis to an AIDS model of Japanese meat demand extending previous approaches in three ways: (1) The methodology employed is robust with respect to the likelihood function but retains the generic, easily programmable character of algorithms offered by Monte Carlo Integration approaches based on the normal likelihood function. (2) In addition to inequality constraints, linear exact restrictions and stochastic prior information are subjected to a Bayesian posterior analysis of validity and incorporated into Bayesian point estimates of model parameters and elasticities. (3) In order to assess the influence of the prior density on posterior distributions of model parameters relative to the likelihood, a measure... |

This paper presents a short comparative analysis of USDA and FAPRI projections for world wheat market prices until 2005. The relevance of different model assumptions regarding assumed inflation, exchange rates, policy parameters as well as shifts in demand and production development are discussed. A subsequent section focuses on the problem of a "world market price concept" for evaluating the potential of unsubsidized EU cereal exports. The Annex provides more detailed information on model assumptions and a comparison of other projected values, also including agricultural products other than wheat. Dieses Diskussionspapier stellt eine kurze vergleichende Analyse aktueller USDA- und FAPRI- Projektionen von Weltmarktpreisen fur Weizen bis 2005 vor. Die... |

The research presented is part of a larger study aiming at the analysis of reform options for the EU sugar policy regime. This paper focuses on the effects of quota reduction and support price cuts. A thorough theoretical analysis investigates the implications of farm heterogeneity for aggregate supply modeling purposes under the current sugar regime. It can be shown that the treatment of sugar quantities produced under the different quotas and without quota can be treated as different products in an aggregate profit function analysis. Marginal and discrete price and quota effects are derived. Subsequently, the derived behavioral characteristics are implemented in the framework of the agricultural sector model CAPSIM to provide a broader policy evaluation.... |

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... |
