The Chinese government is promoting a waste classification policy to solve the increasingly serious issue of cities being besieged by waste. Only few studies investigate whether residents’ understanding of garbage classification policy has an impact on their garbage classification behaviour and the nature of such impact. The purposes of this study are twofold: first, to explore conceptually the mechanism behind any moderating effects of perceived policy effectiveness (PPE) on waste classification and, second, to examine empirically if and how PPE influences the relationships between attitude (ATT), subjective norm (SN), perceived behaviour control (PBC), awareness of consequence (AC) and waste classification intention (WCI). The conceptual model of the study is developed by combining insights from the theory of planned behaviour, norm activation theory and value–belief–norm theory. A total of 351 questionnaires were administered in person to households in Bengbu, China. The results based on structural equation modelling with partial least squares show that PPE negatively moderates the relationship between AC and WCI. AC is more strongly related with the intention to classify waste when PPE is weaker. Likewise, when PPE is higher, people’s awareness of consequences becomes less important for WCI. The findings have significant implications in policymakers’ developing guidelines and offer a framework for implementing more effective waste classification policy.

The per-capita demand of fish and fish products, and paired to it, their production and trade, have substantially increased during the last few decades. For many developing countries these developments open a channel for sustainable economic progress. Against this background, this article investigates whether fish exports Granger-cause long-run economic growth of the agricultural sector (“fish export-led growth”) in a panel of eight South and Southeast Asian countries. A dynamic panel autoregressive distributed lag (ARDL) model is estimated based on data for the years 2000 to 2018. The results indicate that fish exports have a significant positive impact on the growth of the agricultural sector in the long run. These findings apply to both the lower- and the upper-middle-income countries included in the analysis. Long-run Granger causality tests within a panel vector error correction model indicate that agricultural value added per worker reacts to deviations from the long-run equilibrium, whereas fish exports per worker are weakly exogenous. Thus, the paper finds supporting evidence for fish export-led growth. The paper concludes with some thoughts about how this finding can help policymakers in their attempt to induce sustainable agricultural development to eradicate poverty and to enhance living standards.

Factors and motivations that drive individuals’ decisions on seafood consumption vary by population group and geographical locations. These factors may differ from one particular species to the other. The purpose of this study is to understand fish/shrimp consumption frequency and consumers’ willingness to pay (WTP) more for shrimp locally farmed in Togo. We used a Poisson model to investigate the socioeconomic factors determining fish/shrimp consumption frequency, and a Heckman Selection model to analyze the extent to which consumers are willing to pay extra for locally produced shrimp. To this end, data on fish consumption were collected through a cross-sectional study that analyzed a quantitative survey of consumers (N = 308). Our results show that the populations sampled attach great importance to the quality of fish they consume. The econometric results indicate that the quality of the fish is positively related to fish consumption frequency while the monthly income and proximity of the sea show negative relationships with the outcome variable. In addition, the factors that influence the WTP for shrimp were consuming shrimp and the amount for expenditure on fish/shrimp consumption. Moreover, consumers are willing to pay, on average, 1.2 U.S Dollars (USD) as an extra amount relative to the average price per kilogram, and the extent of their WTP is positively related to the quality of the fish. However, the age of the respondents shows a negative relationship with the value they are willing to pay. In order to fulfill consumers’ needs and preferences, these findings jointly suggest that exceptional steps by the government are needed to value fish/shrimp in a way that persuades and encourages consumers to consume seafood at any age. More importantly, promoting the consumption of fish and shrimp requires action to help improve their quality. Government should: (a) be communicating and raising awareness more among the population on the nutritional value and health benefits of fish/shrimp consumption; (b) support fish/shrimp production through cost reduction actions for the fishermen who in turn can supply fish/shrimp at reasonable prices that encourage fish and shrimp consumption; (c) take appropriate measures to develop a logistics system as an effort to support fish, especially shrimp, supply in a timely way that might help to keep their good appearance and freshness for the consumers’ benefit.

Fish products comprise more than 20% of total Ecuadorian exports. Ecuador introduced the “National Green Export Review” (NGER) in 2015, which aims at making Ecuador’s fishing industry more sustainable to improve the international market access to Ecuador’s fish products. Has this policy achieved its goal? In order to answer this question, this article applies the local projection approach to explore the dynamic impact of the NGER on Ecuador’s share of fish exports in the world fish market. Contrary to expectations, the results are consistent with the view that the NGER does not enhance Ecuador’s competitiveness. The NGER is also not able to compensate for the fall in Ecuador’s share in the world fish market, which has been induced by a change in consumer preferences for tuna and shrimp, Ecuador’s main fish products. The concluding section of the paper provides policy advice on how to make the NGER more effective in achieving its goal.
