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 input in the urban unskilled sector is small enough. More restrictive agricultural pollutants control narrows down the wage gap. The impact of an increase in the self-mitigation cost of skilled labour on wage inequality is ambiguous, depending on the factors substitution in agriculture and the elasticity of manufacturing pollution on agricultural production, while a larger self-mitigation cost of unskilled labour brings down the wage gap.

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 of this consumption model. The data has been obtained through on-site interviews and online research on the 56 consumer groups and cooperatives present in Barcelona. Descriptive statistics and correlation analysis have been used to study them. The results prove the salient role that ICT has as a facilitator in the relational network established between the agents that take part in it, thus becoming a key characteristic element of the new agroecological consumer cooperativism.

Abstract: 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 to identify bubbles and consider their evolutions, which is beneficial to the stability of natural rubber price.

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 traceability system by farmers, maintenance of independence by certification agencies, and purchase of herbal products by consumers. The traceability system and existing herbal product safety programs must be refined because they are crucial to consumers, farmers, and people who support agricultural communities. These results contribute to the literature in the field, serving as a reference for members of the herbal product industry, government authorities, and academics.

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 in the long-run. On the other hand, rare high coherence areas at lower scales suggest that monetary and financial activities are most likely the causes that have affected the comovements of the grain prices in the short-term horizons. Phase difference discloses a relatively stable pattern between corn-soybean, corn-wheat, rice-oats and oats-soybean in the longer time-horizons. Taking into account investors' diversification benefits and the leading (lagging) connections in long-run, corn and oats are the most appropriate cereals to be combined in an n-asset portfolio, since these two cereals constantly and very steadily lag soybean, whereas strong coherence between corn and oats does not frequently occur in all wavelet scales.

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 a positive relationship between customer capital and firm performance. However, under high environmental turbulence, customer capital and firm performance are negatively related, meaning that a firm's marketing promotion will be ineffective. This study recommends that the food industry establish a high degree of trust from society and consumers. It is also important for the food industry to establishes a positive attitude towards quality requirements.
