We analyse the effects of GMO regulations on bilateral trade through three main pathways: productivity enhancements in the exporting country, regulatory dissimilarities between trading partners and the influence of GMO approvals on demand in the importing country. Using a panel data set on corn trade and employing advanced econometric techniques, our findings reveal that GMO cultivation approvals in exporting countries have the most substantial and consistent positive effect on trade. Conversely, the impact of GMO demand approvals in importing countries is relatively smaller and negative. Additionally, regulatory dissimilarities between any two countries become negligible when accounting for the effects of cultivation and demand approvals. Thus, GMO approval regulations exert more significant multilateral effects on trade than bilateral ones.","PeriodicalId":55427,"journal":{"name":"Australian Journal of Agricultural and Resource Economics","volume":"69 1","pages":"157-177"},"PeriodicalIF":2.6,"publicationDate":"2024-10-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://onlinelibrary.wiley.com/doi/epdf/10.1111/1467-8489.12591","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143116220","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 doing so, they highlight their regional and varietal distinctiveness while keeping an eye on changes in consumer preferences for different varieties. This paper examines and seeks to explain the extent to which winegrape varietal mixes vary across regions and over time within Australia and relative to the rest of the world. It reports changes in indices of similarity across regions and indices of concentration in the winegrape varietal mix within regions. Nationally, the varietal mix has become less differentiated and closer to that of France and the world as a whole. However, individual regions within Australia are becoming more concentrated in their mix of varieties and more differentiated from other Australian regions. We estimate supply response models based on a Nerlovian adaptive profit expectations and partial acreage adjustment framework. These models do not provide insights into many of the variables influencing vignerons' planting decisions, but they help explain recent changes in varietal mixes. The results suggest that changes in varietal mixes are more motivated by expected revenues than by what may work best based on the climate of each region. In the wake of climate change and global wine demand premiumising, some Australian vignerons may find their region is too warm for producing high-quality wine with the winegrape varieties planted there.","PeriodicalId":55427,"journal":{"name":"Australian Journal of Agricultural and Resource Economics","volume":"69 1","pages":"121-136"},"PeriodicalIF":2.6,"publicationDate":"2024-10-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://onlinelibrary.wiley.com/doi/epdf/10.1111/1467-8489.12594","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143116219","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}

This has increased the incidents of human–wildlife conflict (HWC) due to competition for food and water, further complicating both conservation efforts and food security for farmer-households juxtaposed to wildlife corridors. We seek insights into these issues by examining the role of drought in inducing HWC in rural Zimbabwe and investigate the effect of HWC on the food-security status of rural households. We utilise data from the 2023 nationally representative survey of rural Zimbabwean households in this endeavour. To avoid the confounding problem associated with self-selection into a HWC household and taking into account the count nature of our outcome variable, we employ the endogenous switching regression model with count data. The results provide three major insights. First, drought occurrence increases the likelihood of HWC among rural farmer-households. Second, HWC increases rural household vulnerability to food insecurity. Finally, the HWC shock is inconsequential on farmer-household food insecurity if the farmer-household has already suffered the drought shock.","PeriodicalId":55427,"journal":{"name":"Australian Journal of Agricultural and Resource Economics","volume":"69 1","pages":"232-250"},"PeriodicalIF":2.6,"publicationDate":"2024-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143110602","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 paper applies biological scaling principles to develop a quantity metric in which areas of ecosystem (extent) scale allometrically to ecosystem services (a capacity measure) according to a scaling exponent defined by the fractal dimension of ecosystem vegetation. A key conclusion of this paper is that the quantity of ecosystem services arising from ecosystem degradation and conservation activities cannot be estimated unless information about the space-filling properties of vegetation is observed and included in the quantity measurement methodology. The paper demonstrates how remote sensing techniques can be applied to systematically measure ecosystem extent and fractal dimension. It illustrates the economic efficiency and environmental outcome implications of such a quantity metric through comparison with current quantity estimation methods that assume isometric scaling. The quantity metric proposed has potential applications to ecosystem accounting. It enables information currently reported in land accounts to be combined with information reported in ecosystem condition accounts to create ecosystem stock accounts measured in physical units.","PeriodicalId":55427,"journal":{"name":"Australian Journal of Agricultural and Resource Economics","volume":"68 4","pages":"769-783"},"PeriodicalIF":2.6,"publicationDate":"2024-09-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://onlinelibrary.wiley.com/doi/epdf/10.1111/1467-8489.12590","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142435500","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}

Within Australia's National Electricity Market (NEM), Run-of-Plant (RoP) Power Purchase Agreements (PPAs) became the most common form of contract with purchasers of wind and solar energy agreeing to pay a fixed price for energy irrespective of when it is produced and, therefore, its actual value to the market. In November 2023, the Commonwealth Government adopted a 32 GW RoP PPA Contract-for-Difference (CfD) underwriting policy that aims to effectively shield the generator from market price risk. This article discusses different contract structures and their impact on participant behaviour during periods of material oversupply and negative prices. We find that embedded solar PV exports into the distribution network, which are not required to dynamically participate in the wholesale market, have increased wholesale energy supply, enabling profit maximising vertically integrated renewable firms to drive prices lower in a manner that partially strands the output of RoP PPA CfD generators with a $0/MWh price floor. A key conclusion from our analysis is that requiring embedded solar PV to effectively participate in the wholesale market appears to be a pre-condition for the efficacy of government-initiated RoP PPA CfDs.","PeriodicalId":55427,"journal":{"name":"Australian Journal of Agricultural and Resource Economics","volume":"68 4","pages":"784-804"},"PeriodicalIF":2.6,"publicationDate":"2024-09-05","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://onlinelibrary.wiley.com/doi/epdf/10.1111/1467-8489.12588","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142435164","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}

This study employs a staggered difference-in-differences model to investigate the impact of the Crop Insurance Premium Subsidies Program (CISP) on cropland abandonment using representative household-level panel data from China spanning from 2004 to 2012. Our analysis reveals that crop insurance premium subsidies significantly mitigate cropland abandonment. This relationship is primarily due to the stabilisation of household income growth, which incentivises farmers to augment agricultural inputs and enhance development resilience. Furthermore, our heterogeneous analysis indicates that the effect of the CISP is more pronounced in households located in non-grain-producing regions or areas with lower economic development. These findings underscore the previously overlooked role of crop insurance premium subsidies in preventing cropland abandonment and offer new insights into measures aimed at ensuring food security.","PeriodicalId":55427,"journal":{"name":"Australian Journal of Agricultural and Resource Economics","volume":"68 4","pages":"891-911"},"PeriodicalIF":2.6,"publicationDate":"2024-09-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142435056","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}

The region has high biodiversity values and impressive scenery that provide attractive recreation experiences for visitors. We estimate the value of domestic recreation to the region using a travel cost model. Analysis includes two approaches for accounting for multi-destination trips (MDTs) given travel to remote sites are more likely to include these than shorter trips, and four specifications for the value of travel time. We estimate a total consumer surplus of A$110.34 million annually and find that adjusting travel costs for MDTs using stated survey information produces a better fitting model than using revealed travel information.
