COVID-19, spatial market integration and producer prices: A case study of EU agri-food markets

The spread of COVID-19 has had a significant impact on economic and social activities, with the agri-food sector being no exception. Since the COVID-19 outbreak, numerous studies investigating its sectoral influence have been carried out, putting emphasis on demand and supply shocks and changes in trade volumes. However, there has not been much research into the implications of the pandemic for prices. To fill the research gap, this paper is an attempt to examine the impact of COVID-19 on producer prices in the EU-27 in Q2 and Q3 of 2020. The study is based on monthly data on trade in agri-food commodities according to the SITC classification in 2015-2020 and the monthly producer prices index of food (2015 = 100) in the EU countries. It was assumed that the agri-food trade balance is the key factor determining the level and changes of domestic prices. The theoretical background for empirical research is provided by a spatial partial equilibrium model and the concept of spatial market integration. The results of the study reveal that there is a negative and statistically significant relationship between an export-import ratio (which illustrates the country’s self-sufficiency level) in the pre-COVID-19 period and price changes in Q2 of ...

Implications of conceptual and data complexities on time-series econometric applications in market integration analysis

This article demonstrates and highlights the conceptual limits of current empirical market integration (MI) time series models (threshold models) and their implications on market efficiency and competitive equilibrium conclusions. The complexities and diversities that characterise the analysis of the concept of market integration are evaluated within the framework of EnkeSamuelson-Takayama-Judge (ESTJ) spatial equilibrium theory. The efficiency and competiveness implications drawn from MI models are limited by how the data generation process (DGP) is influenced by equilibrium conditions, by the tradability restrictions of the inter-markets relationships and by the presence of unobserved transactions costs. However, empirical applications scarcely address these limitations. Two sets of synthesized data with varying levels of non-linear complexity implied by alternating equilibrium conditions are generated to demonstrate conceptual limits of current threshold models in market integration analysis. Inconsistent conclusions that linear representations imply for threshold propagated DGP will also apply for conclusions derived from threshold models if markets are characterised by switching equilibria conditions.
