Due to their low opportunity costs and high availability, university students are frequently recruited as the study population. Even though they are rather untypical with regard to many characteristics (e.g. age and income) compared to the representatives of the social group of interest, the experimental behaviours of students are sometimes prematurely generalised to other social groups or even to humans in general. Given the widespread challenges in the agricultural and environmental sector, it is particularly interesting to address farmers' decision-making. We analyse whether agricultural students can be used to approximate the behaviour of farmers in simple economic experiments, which are often used to measure risk aversion, impatience, positive reciprocity, negative reciprocity, altruism and trust. Moreover, we consider the role of systematically varied monetary incentives. We find no differences between agricultural students and farmers in their risk aversion; farmers' positive reciprocity and trust are positively associated with the incentive level, which cannot be observed with agricultural students. Findings regarding altruism in the two populations are mixed and challenge the finding of earlier studies of students being less pro-social. Agricultural students are a lower boundary of impatience and negative reciprocity. These heterogeneous results suggest that scientific inference from agricultural students to farmers should be made cautiously. However, we do not deal with a representative sample of our target population (e.g. gender). Replication studies are required to evaluate the generalisability of our findings.","PeriodicalId":55427,"journal":{"name":"Australian Journal of Agricultural and Resource Economics","volume":"66 3","pages":"471-504"},"PeriodicalIF":3.2,"publicationDate":"2022-06-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://onlinelibrary.wiley.com/doi/epdf/10.1111/1467-8489.12485","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"49136230","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"经济学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

We analyse the spatial diffusion of more efficient irrigation strategies in São Paulo, Brazil, comparing the two most common irrigation technologies: conventional sprinkler irrigation and the localised irrigation. We use longitudinal municipal-level information for 2006 and 2017 and test different spatial panel models' specifications, representing different hypotheses about technological transfer channels. Our results highlight how the diffusion of water-saving irrigation systems (localised irrigation) in one municipality is strongly influenced by the diffusion in neighbouring municipalities. Membership in cooperatives or farmers' associations plays a significant role in this technological transfer. On the other hand, the diffusion of less efficient systems (sprinkler irrigation) depends fundamentally on the local availability of water and unobservable factors in the neighbourhood. The discussion highlights how easing knowledge transmission may contribute to the diffusion of more sustainable agriculture practices.","PeriodicalId":55427,"journal":{"name":"Australian Journal of Agricultural and Resource Economics","volume":"66 3","pages":"690-712"},"PeriodicalIF":3.2,"publicationDate":"2022-06-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"43857548","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"经济学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This study explores consumer willingness to pay (WTP) to achieve higher environmental standards for sugar originating from the GBR catchments, through the use of a GBR-safe ecolabel. A Best-Worst Scaling (BWS) and a Contingent Valuation (CV) experiment are conducted on a random sample of 1,100 Australian residents. The BWS experiment reveals that personal health considerations are more important than sustainability and environmental factors, including impacts on the GBR. Results of the CV experiment show that respondents are more likely to pay a premium to support Reef-friendly sugar if they are living in urban areas, plan to visit the GBR in the future, think that the GBR condition has declined, and are generally concerned about keeping a healthy diet. We estimate that the average WTP is $24.5/year/household, which only represents 0.34 per cent of the average weekly grocery bill of Australian households. This small contribution through increased sugar prices could conservatively raise $46.9M/year in support of sugar producers to improve water quality in the GBR. Based on these results, we recommend policy-makers consider instruments that further involve sugar consumers.","PeriodicalId":55427,"journal":{"name":"Australian Journal of Agricultural and Resource Economics","volume":"66 3","pages":"505-531"},"PeriodicalIF":3.2,"publicationDate":"2022-06-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://onlinelibrary.wiley.com/doi/epdf/10.1111/1467-8489.12484","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"46852764","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"经济学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Four scenarios are simulated showing the trade and production effects of a gradual phasing-out of EU domestic support measures and EU import tariffs using two partial equilibrium models linked to each other. Compared with previous work, tariff rate quotas are represented in great detail, going beyond the classical single-origin, single-destination approach. Furthermore, supply functions of EU sugar processors are calibrated based on empirical data on production costs to overcome the problem of non-observed production costs due to the existence quota rents. Results suggest that, in particular, sugar production in Balkan countries is adversely affected by a liberalisation of the EU sugar regime. Moreover, the simulation shows that preferential LDC-ACP exporters, among them Fiji and Papua New Guinea, are displaced from the EU market leading to a decline in production. An elimination of EU import tariffs benefits in particular the Ukraine and the world's largest sugar producers, such as Australia, all with currently only limited preferential market access to the EU. During periods of low global sugar prices, these countries even increase sugar production, if the EU sugar market is completely liberalised.","PeriodicalId":55427,"journal":{"name":"Australian Journal of Agricultural and Resource Economics","volume":"66 3","pages":"638-667"},"PeriodicalIF":3.2,"publicationDate":"2022-06-05","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://onlinelibrary.wiley.com/doi/epdf/10.1111/1467-8489.12475","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"46417538","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"经济学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Our findings document that the world's second-largest rice exporter could produce 4 million tonnes more rice with the same water supply in the reasonably achievable case of 20 per cent SRI uptake across its provinces. In addition, we find that SRI also increases the output of other crops, due at least partly to its possible water savings and soil nutrition preservation in rice production. Moreover, we show that SRI is more likely to be adopted in provinces with a stronger quality of provincial institutions and a weaker agricultural capital base. Numerous selectivity and randomisation tests affirm that the water productivity effect of SRI is robust to selection in SRI uptake at the province and district levels and addressing potential unobservable and omitted variable problems.","PeriodicalId":55427,"journal":{"name":"Australian Journal of Agricultural and Resource Economics","volume":"66 3","pages":"581-611"},"PeriodicalIF":3.2,"publicationDate":"2022-06-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://onlinelibrary.wiley.com/doi/epdf/10.1111/1467-8489.12477","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"45365448","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"经济学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In this study, instrumental variables models are constructed to estimate the influence of the farm size and the number of farmland plots on household welfare proxied by income and the asset index in Vietnam. The study exploits the panel data of households collected from the Vietnam Access to Resources Household Survey (VARHS) every second year in the period 2008–2014, capturing cultural, political and socioeconomic dimensions of rural Vietnam. A positive relationship was found between farm size and household economic welfare proxied by household per capita income and a household asset index; however, this relationship was negative for the number of land plots. The main conclusion from our analysis is that household welfare would be aided by land policies towards increasing the size of farmland and decreasing land fragmentation. However, our findings also indicate that to be effective, these land policies should be complemented by rural education, effective community development and encouragement of non-farm employment activities.","PeriodicalId":55427,"journal":{"name":"Australian Journal of Agricultural and Resource Economics","volume":"66 3","pages":"561-580"},"PeriodicalIF":3.2,"publicationDate":"2022-05-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://onlinelibrary.wiley.com/doi/epdf/10.1111/1467-8489.12476","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"46768317","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"经济学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
