A Comparison of Threshold Cointegration and Markov-Switching Vector Error Correction Models in Price Transmission Analysis 31
Ihle, Rico; von Cramon-Taubadel, Stephan.
We compare two regime-dependent econometric models for price transmission analysis, namely the threshold vector error correction model and Markov-switching vector error correction model. We first provide a detailed characterization of each of the models which is followed by a comprehensive comparison. We find that the assumptions regarding the nature of their regime-switching mechanisms are fundamentally different so that each model is suitable for a certain type of nonlinear price transmission. Furthermore, we conduct a Monte Carlo experiment in order to study the performance of the estimation techniques of both models for simulated data. We find that both models are adequate for studying price transmission since their characteristics match the underlying...

A DISCOURSE ANALYSIS APPROACH TO EXPLAIN THE PATH DEPENDENCY OF SEASONAL FARM LABOUR REGULATIONS IN GERMANY 31
Hess, Sebastian; Kleinschmit, Daniela; Theuvsen, Ludwig; von Cramon-Taubadel, Stephan; Zschache, Ulrike.
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...

A Note on Technical Efficiency, Productivity Growth and Competitiveness 31
Nivievskyi, Oleg; Brümmer, Bernhard; von Cramon-Taubadel, Stephan.
‘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...

Agglomeration Economies in Ukrainian Dairy Sector: a Marked Point Process Approach 31
Brümmer, Bernhard; von Cramon-Taubadel, Stephan; Nivievskyi, Oleg; Schlather, Martin.
Even after more than 15 years of transition from plan to market, agriculture in Ukraine still faces many challenges in terms of its structure. The evidence in the literature points to significant heterogeneity of technical efficiency and productivity scores in Ukraine. Moreover, both the recently approved WTO accession, and the ongoing negotiations on a free trade agreement with the EU will require further improvements in productivity and competitiveness at the farm level. Using farm-level data for 2004-2005, we study the presence and possible causes of agglomeration economies in Ukrainian dairy sector. One of the most important results is that there are agglomeration effects in the sector. The performance of dairy farms is influenced by the performance of...

Agricultural Trade Policy Modelling: Insights from a Meta-Analysis of Doha Development Agenda Outcomes 31
Hess, Sebastian; von Cramon-Taubadel, Stephan.
In a meta-analysis of trade policy models, Hess and von Cramon-Taubadel (2008) use over 5800 simulated welfare effects from 110 studies of potential Doha Development Agenda outcomes to identify characteristics of models, data and policy experiments that influence simulation results. This meta-analysis, which is recapitulated here, produces plausible results and explains a significant proportion of the variation in simulated welfare effects. However, due to insufficient documentation and the complexity of the general and partial equilibrium models in the literature sample, many explanatory variables employed in this analysis are binary. This precludes more detailed analysis of their impacts across models. Therefore, a partial equilibrium model and a single...

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...

Asymmetric Price Transmission in the Israeli Citrus Export Sector in the Aftermath of Liberalization 31
von Cramon-Taubadel, Stephan; Goetz, Linde.
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...

Considering threshold effects in the long-run equilibrium in a vector error correction model: An application to the German apple market 31
Goetz, Linde; von Cramon-Taubadel, Stephan.
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...

Country and border effects in the transmission of maize prices in Eastern Africa: evidence from a semi-parametric regression model 31
Ihle, Rico; von Cramon-Taubadel, Stephan; Zorya, Sergiy.
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...

Data Aggregation and Vertical Price Transmission: An Experiment with German Food Prices 31
von Cramon-Taubadel, Stephan; Loy, Jens-Peter; Meyer, Jochen.
The impact of cross sectional aggregation over individual retail stores on the estimation and testing of vertical price transmission between the wholesale and retail levels is investigated using a unique data set of individual retail prices in Germany. Systematic differences between the results of estimations using aggregated data on the one hand, and disaggregated data on the other, are discussed theoretically and confirmed empirically. The results suggest that estimation with aggregated data generates misleading conclusions about price transmission behavior at the level of the individual units (i.e. retail stores) that underlie these aggregates.

Grenzeffekte in der Marktintegration bei Mais in Ostafrika: Einsichten aus einem semi-parametrischen Regressionsmodell 31
Ihle, Rico; Amikuzuno, Joseph; von Cramon-Taubadel, Stephan; Zorya, Sergiy.
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...

Measuring Price Transmission in the International Fresh Fruit and Vegetable Supply Chain: The Case of Israeli Grapefruit Exports to the EU 31
Goetz, Linde; von Cramon-Taubadel, Stephan; Kachel, Yael.
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...

Meta Response Surface Design for General and Partial Equilibrium Models 31
Hess, Sebastian; von Cramon-Taubadel, Stephan.
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...
