Drawing on recent structural transformation literature, this paper seeks explanations for this unusual phenomenon, which is all the more striking because agriculture's share of employment continued to decline throughout and growth in manufacturing was being stimulated by tariff protection from imports. Several factors contributed, including a huge land frontier that took more than a century for settlers to explore, rapid declines in initially crippling domestic and ocean trade costs for farm products, the absence of a need to do any processing of the two main exports during that period (gold and wool) and innovations by farmers and via a strong public agricultural R&D system that contributed to farm labour productivity nearly doubling over those 10 decades. The ban on iron ore exports from 1938 and low export prices for fuels, minerals and metals during the two world wars and in the intervening decades also contributed.","PeriodicalId":55427,"journal":{"name":"Australian Journal of Agricultural and Resource Economics","volume":"68 1","pages":"1-22"},"PeriodicalIF":3.2,"publicationDate":"2023-11-09","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://onlinelibrary.wiley.com/doi/epdf/10.1111/1467-8489.12540","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"135242697","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}

To provide insights into the importance of representing weather-year sequence in farm modelling, two whole-farm optimisation models are constructed and applied to a mixed enterprise farming system in a subregion of Western Australia. The frameworks are (i) four-stage single-sequence stochastic programming with recourse (4-SPR) to capture weather-year variation and management tactics tailored to each weather-year and (ii) eight-stage multi-sequence stochastic programming with recourse (8-SPR) to outline weather-year sequences and management tactics tailored to particular weather-year sequences. Results show that single-year stochastic programming generates similar expected profit and strategic management as multi-year stochastic programming. However, optimal tactical farm management is affected by the outcome of the previous year. Tactical decision-making in response to the outcome of the preceding weather-year increases profitability by 14%. Technology changes over the last decade, particularly the increase in computer speed and computational power, increase the ease of construction and application of the 4-SPR and 8-SPR frameworks. Nonetheless, choosing which framework is best to apply to a particular issue or opportunity remains a challenge.","PeriodicalId":55427,"journal":{"name":"Australian Journal of Agricultural and Resource Economics","volume":"68 1","pages":"44-59"},"PeriodicalIF":3.2,"publicationDate":"2023-11-05","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://onlinelibrary.wiley.com/doi/epdf/10.1111/1467-8489.12539","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"135726258","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 test whether grassroots programs can additionally relax behavioural constraints, potentially enhancing the adoption of diversified production systems. In Odisha, India, using a series of laboratory-in-field experiments and survey instruments to elicit farmers' preferences for risk, agency and aspirations for themselves and their children, we find that respondents in villages where grassroots interventions were promoted showed significantly lower levels of risk aversion and higher aspirations for themselves and their children, along with improvements in production and consumption diversity. However, we do not find a mediating role of reduced risk aversion in improving direct program outcomes. Our results show that grassroots approaches are effective in inducing a shift towards changing production systems, and relaxing behavioural constraints, that can be leveraged over time to strengthen impacts.","PeriodicalId":55427,"journal":{"name":"Australian Journal of Agricultural and Resource Economics","volume":"68 1","pages":"101-124"},"PeriodicalIF":3.2,"publicationDate":"2023-10-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"135413457","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}

While many studies have found that CA increases farm productivity, little is known about the components of the productivity gains related to CA adoption. CA is a knowledge-intensive technology, and it is expected to affect both technical efficiency (TE) and input productivity positively. Using cross-sectional farm-level data of 220 maize farmers in Bangladesh, we measure the impact of CA on farmers' TE. We first apply propensity score matching (PSM) to create comparable counterfactual groups of CA and non-CA farmers. Then, we use a stochastic frontier with correction for self-selection bias to analyse TE. Finally, we fit a stochastic meta-frontier (SMF) model to the data and use it to compare TE across the two farmer groups. The analysis showed that CA farmers exhibit greater TE levels than non-CA farmers. This can be attributed to enhancements in farm management, leading to 8% and 9% increases in their productivity and TE, respectively. Thus, there is a case for policymakers to strengthen programs delivering CA technologies that improve food security in Bangladesh.","PeriodicalId":55427,"journal":{"name":"Australian Journal of Agricultural and Resource Economics","volume":"68 1","pages":"125-145"},"PeriodicalIF":3.2,"publicationDate":"2023-10-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://onlinelibrary.wiley.com/doi/epdf/10.1111/1467-8489.12537","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"135859103","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}
