This paper focuses on the volatility spillover effects among crude oil, metals, agriculture, and non-energy commodity markets. The results show financialization has an impact on the volatility of commodity prices, predominantly for non-energy commodities. However, the impact on volatility is not symmetric across all commodities. The analysis of index investment and investors’ positions in futures markets shows that, when a relationship exists, it is generally negatively correlated with the realized volatility of non-energy commodities. Using realized volatility in the difference-in-difference model provides estimates that are inconsistent with other findings that non-energy commodities, traded as a part of indices, have experienced higher volatility. The results are similar to the index investment and futures market analysis, where increased participation by investors through new investment products has put download pressure on realized volatility.","PeriodicalId":415933,"journal":{"name":"Agricultural Science Research Network (Forthcoming)","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-10-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"122534807","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}

Frempong","doi":"10.2139/ssrn.3230678","DOIUrl":"https://doi.org/10.2139/ssrn.3230678","url":null,"abstract":"In response to the perennial low harvest and high food prices, a number of Sub-Saharan African countries have instituted agricultural input subsidy programmes to increase food production and reduce poverty among small-scale farmers. Given that agriculture employs a large portion of working children on the continent, this paper studies the effect of these subsidy programmes on child labour. The paper analyses three rounds of the Malawi Integrated Household Panel Survey to answer the research question. The econometric results show that the farm input subsidy program in Malawi has a significant and positive impact on child labour in the country. The results suggest that in spite of the success of the programme in achieving its core aims, there are unintended negative consequences that could negatively affect human capital development. This could in turn adversely affect the ultimate poverty eradication efforts in the country and in the sub-region. To mitigate this problem, governments and implementing agencies should consider conditioning the distribution of the inputs on positive outcome like the school performance of the wards of beneficiaries.","PeriodicalId":415933,"journal":{"name":"Agricultural Science Research Network (Forthcoming)","volume":"93 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-08-31","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114070788","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}

Agriculture, End to End 农业，端到端

Chen","doi":"10.2139/ssrn.3218894","DOIUrl":"https://doi.org/10.2139/ssrn.3218894","url":null,"abstract":"Agriculture consists of a process for converting energy and biological information into physical products for human consumption. Increasingly sophisticated biotechnology in agricultural inputs makes manifest this definition of agriculture as information flow. The architectural ideal in information science is the end-to-end principle. All intelligence within an information platform arises from its ends. The corollary of the end-to-end principle, however, is that intervening layers facilitating the transmission of intelligence become “dumb pipe,” whose sole contribution consists of efficient transport of information. Within its own domain, agriculture has become dumb pipe. The rise of bioengineered inputs has rendered obsolete the evolutionary contribution of farmers. At the other end of the value chain, consumer-driven preferences in food restrict the inputs that farmers may deploy. “Intelligence” propelled by preferences and tastes among affluent consumers constrain choices traditionally exercised by farmers. This exercise in virtue signaling exerts further competitive pressure. Driving all intelligence in the agricultural supply chain to its ends — where biotechnology reinvents basic inputs in an epoch of resource exhaustion and where consumer tastes dictate practices on the farm — compels a fundamental reevaluation of agriculture’s legal and economic premises.","PeriodicalId":415933,"journal":{"name":"Agricultural Science Research Network (Forthcoming)","volume":"13 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-07-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130387781","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}
