This article introduces discourse analysis as a theoretical concept and an empirical methodology that may enable the endogenization of path creation and path breaking changes in conventional models of political path dependencies. Economic criteria such as rents created by a policy do not always provide a comprehensive explanation for path dependent political decisions. Discourse theory implies that specific interpretative schemata and narratives, such as storylines in the mass media, heavily influence the political discourse. Discourses themselves exercise a constitutive power that constrains decision-making processes and, thus, influence the ensuing policy creation path. Hence, discourses must be taken into account when political path creation is... |

‘Productivity and efficiency growth enhances competitiveness’. Similarly formulated statements are common in the literature on the economic performance of firms, industries and nations. This conventional perception in the economic literature, originating from trade and growth theory models, however, lacks a clearly defined mathematical formulation. Earlier work by Page (1980) and Nishimizu and Page (1986) provides an elegant formalization of the relationship between the productivity growth and competitiveness measured by the Domestic Resource Costs (DRC) ratio. However, the relationship between technical efficiency and competitiveness has not been addressed in the literature. Moreover, the DRC is a biased measure of competitiveness. We propose static and... |

Since the late 1980s, agriculture in Central and Eastern European Countries (CEECs) has been under considerable adjustment pressure due to changing political, economic and institutional environments. These changes have been linked to the transition process, as well as the ongoing integration into the European Union and the world market. Reduced subsidies, increased environmental and food quality demands, as well as structural changes in the supply, processing and food retailing sector call for major structural adjustments and the improvement of farmers’ managerial abilities. Though such changes always carry significant threats to farms, they also offer new opportunities for the farms' entrepreneurial engagement. Upcoming changes in the agricultural... |

The Israeli citrus export sector was liberalized in 1991 with the aim to increase citrus growers' income and to improve overall efficiency of the international citrus marketing channel. However, the former government export monopoly's activities were mainly taken over by four large companies accounting for over 90% of total Israeli citrus market exports. In addition, citrus exporters maintained the monopoly's consignment system, substantially limiting transparency on how the grower price is determined. This lead the government to intervene in the newly liberalized market by implementing a minimum price agreement in the 1994/95 season to protect citrus growers against exporters' abuse of market power. In this paper we analyze whether market power was... |

We propose a three-step procedure to estimate a regime-dependent vector error correction model (VECM). In this model, not only the short-run adjustment process towards equilibrium is non-linear, as in threshold VECM and Markov switching VECM frameworks, but the long-run equilibrium relationship itself can also display threshold-type non-linearity. The proposed approach is unique in explicitly testing the null hypothesis of linear cointegration against the alternative of threshold cointegration based on the Gonzalo AND PITARAKIS (2006) test. The model is applied to apple price data on wholesale markets in Hamburg and Munich, using the share of domestic apples in total wholesale trade as the threshold variable. We identify four price transmission regimes... |

This study uses a rich dataset of 85 market pairs between January 2000 and October 2008 for Kenya, Tanzanian and Uganda, the three largest member countries of the East Africa Community, to analyze the factors determining national and cross-national maize price transmission. Although the three countries are members of the community’s customs union and they each claim to pursue maize trade without borders, their agricultural trade policies still differ, thus affecting prices and trade flows to different extents. This analysis extends the existing border effects literature in three ways. First, it assesses the magnitude of price transmission, instead of analyzing trade flows or price variability. Second, distance is shown to have a significant impact on price... |

Diese Arbeit analysiert Faktoren, die Einfluß auf das Ausmaß der inländischen und grenz-übergreifenden Integration der Maismärkte Kenias, Tansanias und Ugandas ausüben. Die Stärke der Reaktion der Preise auf Abweichungen von ihren Langzeitgleichgewichtswerten als Maß der Marktintegration und die Determinanten dieser Reaktion werden für 85 Marktpaare von Januar 2000 bis Oktober 2008 untersucht. Zu diesem Zweck wird ein semi-parametrisches partiell-lineares Regressionsmodell genutzt, das imstande ist, den Einfluß der Marktentfernung, der sich als nichtlinear herausstellt, adäquat zu modellieren. Die Ergebnisse der Untersuchung sind kohärent mit der ökonomischen Theorie und von politischem Interesse. Ein Grenzeffekt wird identifiziert, der in dem Sinne... |

We study vertical price transmission between Israel and the EU in the imperfectly competitive Israeli citrus export sector, which emerged after the former parastatal marketing board was liberalised in 1991. We find evidence of positive asymmetry in price transmission, implying that Israeli exporters’ profits increase at the expense of grapefruit growers, and we argue that this is evidence that Israeli citrus exporters exert market power vis-à-vis Israeli citrus growers. This study is unique in investigating vertical price transmission in the international supply chain for fresh fruits and vegetables (FFV). International FFV trade is especially susceptible to the abuse of market power since transparency regarding the determination of the grower price is... |

Due to the complexity of general and partial equilibrium models, conventional sensitivity analysis, qualitative reviews or literature-based meta-analyses do not allow for detailed assessments of the role of individual parameters and policy shocks across different models. Therefore, the partial equilibrium model “GSIM” and a single country CGE are employed to generate synthetic scenarios based on randomly specified combinations of base data, elasticities and tariff changes selected from previously specified, plausible ranges. The synthetic meta-data has the advantage that the values of explanatory variables are measured exactly. This makes it possible to explore complex issues of functional form and interaction between variables in the estimation of the... |
