However, as adopting innovations can lead to risks, it is important to understand the role of farmers’ risk attitudes. We quantified Dutch arable farmers’ risk attitudes based on the Cumulative Prospect Theory (CPT), and used the Benefit of the Doubt (BoD) approach to obtain an innovation index based on expert elicitations and adopted innovations. Subsequently, we used a Fractional Response Model to test our pre-registered hypothesis and investigate the association between the parameters of farmers’ risk attitude and farm level innovation. We find no statistically significant association between CPT parameters and the innovation index. Our results therefore cast doubts on the potential of revealed risk preferences to understand real-world behaviour.","PeriodicalId":87350,"journal":{"name":"Q open","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2023-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"135510074","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

They can also address habitat fragmentation if a bonus is added to the homogenous base payment when conservation measures are implemented next to other conserved lands. However, if conservation costs differ spatially, the spatial aggregation of habitat can be costly, and the cost-effective generation of contiguous habitats is an issue. Here we use a stylised agent-based simulation model to demonstrate that land-use induced by agglomeration bonus schemes can exhibit hysteresis, meaning that the amount and aggregation of conservation is to some extent resilient to changes in payment levels. This suggests that staggered payment schemes in which a relative large bonus is used to establish a habitat network and lowered afterwards to a level sufficient to sustain the habitat network, may be more cost-effective than a scheme with a constant bonus. We show that low base payments and relatively high bonuses can create hysteresis, and staggered payments based on this design principle can—especially at high spatial variation of conservation costs and long-term time preference in the decision maker—generate cost-effectiveness gains.","PeriodicalId":87350,"journal":{"name":"Q open","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2023-10-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"136078791","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Worldwide, countries have set agricultural GHG reduction goals and discussed methods to reach them. A crucial aspect is, whether the policy target level is set at the individual farm or at a regional level. In this context, we assess the advantages regarding cost-effectiveness and GHG-reduction potential of targets at the regional level. First, we use the bioeconomic farm-level model FarmDyn to simulate the changes in income and GHG emissions of 65 Swiss dairy farms. Secondly, we develop an optimization algorithm to compare the efficiency and efficacy of these two target approaches. Our analysis reveals that regional targets, which consider the heterogenous abatement costs of the sector, are more cost-efficient than farm-level ones. Specifically, they enable a 10 per cent GHG reduction at 88 per cent lower costs, suggesting they might be a more cost-effective alternative to taxation.","PeriodicalId":87350,"journal":{"name":"Q open","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2023-10-06","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"134944384","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

We estimate the impact of biofuel plants on the agricultural economy with county-level data on the number of farm operators, net farm income, and agricultural land values during 1997 to 2017 for 798 counties in twelve Great Plains states. We find that biofuel production facilities have a small negative association with the number of farm operators, but positive associations with net farm income and farmland values in the county where the biofuel plant is located and neighboring (adjacent) counties. Sustained positive associations of biofuel production with farm income and land values are likely to depend on the continuation of national and state government programs of ethanol blend mandates and tax credits. Diminished government bioenergy support could lead to declining farm income and land values in areas near plants.","PeriodicalId":87350,"journal":{"name":"Q open","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2023-09-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"135579944","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This may cause different carbon prices for climate gasses across countries, between a country's emission sectors, and within the same sector. Our focus is on methane, which is a major emitter from agriculture, but also linked to livestock farming which is a core activity in agriculture worldwide. We analyse the potential effects of domestic carbon pricing regimes for agriculture in a non-cooperative game theoretic setting using a global agricultural sector model. Our results indicate no ‘race to the bottom’ to apply carbon pricing regimes that result in lowest implicit carbon prices for methane. Enforcing a uniform regime can reduce additional global warming with up to 0.02 °C, but runs the risk of agreeing to lower emission cuts than a nationally determined choice would suggest.","PeriodicalId":87350,"journal":{"name":"Q open","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2023-07-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"48936335","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This study uses data from a 2018 survey of 763 vegetable smallholder farms in China to estimate the impact of ICT on technical efficiency (TE). We adopt propensity score matching to create a balanced sample of ICT users and non-users, and a stochastic frontier model with sample selection correction to compare the two groups’ TE. After accounting for self-selection bias from both observables and unobservables, the study finds a positive effect of ICT use on TE. On average, the TE score of ICT users is 0.64, whereas ICT non-users have a lower score of 0.57. A quantile regression analysis further reveals a heterogeneous impact of ICT on TE, with the largest effects among less efficient farms. These results suggest that vegetable farmers’ performance could be fostered by the widespread use of ICT.
