The Impact of an EU–US Transatlantic Trade and Investment Partnership Agreement on Biofuel and Feedstock Markets 下载免费PDF全文
John C. Beghin Jean‐Christophe Bureau Alexandre Gohin 《Journal of Agricultural Economics》2017,68(2):321-344
We assess the impact of a potential TTIP bilateral free trade agreement on the EU and US bio‐economies (feedstock, biofuels, by‐products, and related competing crops) and major trade partners in these markets. The analysis develops a multi‐market model that incorporates bilateral trade flows (US to EU, EU to US, and similarly with third countries) and is calibrated to the OECD‐FAO baseline for 2013–2022 to account for recent policy decisions. The major policy reforms from a TTIP involve tariff and TRQ liberalisation and their direct contractionary impact on US sugar supply, EU biofuel production, and indirect negative effect on US high fructose corn syrup (HFCS) production. EU sugar and isoglucose production expand along with US ethanol and biodiesel and oilseed crushing. EU sugar would flow to the US, US biofuels and vegetable oil to the EU. We further quantify non‐tariff measures (NTM) affecting these trade flows between the EU and the US. EU oilseed production contracts, and EU crushing expands with improving crushing margins following reduced NTM frictions. Our analysis reveals limited net welfare gains with most net benefits reaped by Brazil and not the two trading partners of the TTIP. 相似文献

The Rise and Decline of Small‐Scale Sugarcane Production in South Africa: A Historical Perspective 下载免费PDF全文
Alex Dubb 《Journal of Agrarian Change》2016,16(4):518-542
South Africa's sugar industry has long been distinguished by its large number of small‐scale sugarcane growers (SSGs) farming on ‘communal’ land and its peculiar privately administered regulatory structure. In recent years, however, the numbers of small‐scale growers have declined precipitously. This paper argues that the relationship between the rise and fall of SSG production and the industry's governing regulatory structure is closer than usually appreciated. The emergence of SSG production in the late 1970s and the 1980s can be traced to industry‐subsidized initiatives, disguised as small‐scale credit, to bring commercially inalienable Bantustan land into cane production with strong miller oversight. From the late 1980s to 1990s, however, the elimination of these subsidies encouraged millers to subcontract support to farmers, while simultaneously instigating an increase in SSG numbers by removing restrictions on grower registration. Although low rainfall is a central proximal factor in the rapid decline of the SSGs in the 2000s, their rapid increase was structurally fragile. 相似文献
