Agric. Econ. - Czech, 2019, 65(2):51-58 | DOI: 10.17221/79/2018-AGRICECON  

The paper incorporates manufacturing and agricultural pollution into a three-sector general equilibrium model with pollution externalities both on agricultural production and labour health. Manufacturing generates pollution that affects agricultural production and health, while agriculture employs the pollutant as a factor for production that only affects health. Under the framework, this paper investigates the impacts of environmental protection policies and a rise in the self-mitigation cost of skilled and unskilled labour on wage inequality. A larger environmental tax expands wage gap if partial elasticity of substitution between labour and dirty...

In Catalonia, agroecological cooperativism is part of a set of alternatives that appeared as a response to the current hegemonic food consumption model, controlled by large commercial establishments. It is defined by its promotion of short food supply chains (SFSCs), operates under the values of the social and solidarity economy (SSE) and holds a strong political commitment. This article, on the one hand, studies the setup of agroecological cooperativism understood as the outcome of a network of producers, intermediaries and consumers and, on the other hand, examines the impact of information and communication technologies (ICT) in the development...

In this paper, we employ the Generalized Supremum Augmented Dickey-Fuller test in order to identify the existence of multiple bubbles in natural rubber. This approach is practical for the using of time series and identifies the beginning and end points of multiple bubbles. The results reveal that there are five bubbles, where exist the divergences between natural rubber prices and their basic values on account of market fundamentals. The five bubbles are related to imbalance between supply and demand, inefficiencies of smallholders market, oil prices, exchange rate and climatic changes through analyses. Thus, the corresponding authorities are supposed...

Analysing the traceability system in herbal product industry by game theoryOriginal Paper

Mao-Chang Wang, Chin-Ying Yang

Agric. Econ. - Czech, 2019, 65(2):74-81 | DOI: 10.17221/102/2018-AGRICECON  

The agricultural traceability system provides information transparency throughout the agricultural supply chain. This paper applies game theory to analyse the traceability system used by the herbal product industry in order to elucidate the strategic choices made by government authorities, farmers (e.g. producers), certification agencies, and consumers. This paper clarifies how relevant variables affect the traceability system employed in the herbal product industry. The analysis yields strong results and indicates a superior equilibrium; the observed strategic choices comprise active traceability system promotion by authorities, development of a comprehensive...

Multiscale interdependence between the major agricultural commoditiesOriginal Paper

Dejan Živkov, Jovan Njegić, Marko Pećanac

Agric. Econ. - Czech, 2019, 65(2):82-92 | DOI: 10.17221/147/2018-AGRICECON  

This paper investigates multiscale dynamic interconnection between the five agricultural commodities - corn, wheat, soybean, rice and oats, covering more than 18 years period. For research purposes, two complementary methodologies were used - wavelet coherence and phase difference. Low coherence is present at shorter time-horizons, while at longer time-horizons high coherence areas are found, but they are not widespread in all wavelet coherence plots. These results speak in favour of diversification opportunities. Strong coherence in longer time-horizons indicates that common factors are likely to be the main determinants of the agricultural prices...

Firms' profitability from firm-specific factor, environmental turbulence, and macroeconomic: evidence from Taiwan's food industry - A reviewReview

Joe-Ming Lee, Shiu-Wan Hung, Chiao-Ming Li

Agric. Econ. - Czech, 2019, 65(2):93-101 | DOI: 10.17221/134/2018-AGRICECON  

After a series of shocking domestic food safety scandals in the past few years, environmental concerns have risen in the eyes of the public. The aim of this paper is to analyse the relationships among firm performance, customer capital, R&D innovation, structural capital, firm asset, environmental turbulence, and the macroeconomy by using the panel data model on Taiwanese food industry firms during 2010-2016 and by examining the results of the multiple regime panel smooth transition regression (MR-PSTR) model. The findings show that environmental turbulence and the misery index have a negative relationship on firms' performance, while there is...
