Lead roasting firms are operating through Indonesia's coffee exporters to introduce voluntary sustainability standards (VSS) in an attempt to secure supply, and to simultaneously meet corporate social responsibility requirements, even as empirical studies continue to show uncertain benefits for producer livelihoods. Value chain interventions like VSS, however, are not rolled out over a blank canvas, and many contributing factors determine their overall impact on livelihoods, particularly the local institutional environment. This study assesses the extent to which variability of empirical outcomes is determined by the institutional environment, by identifying specific processes through which VSS interact with pre‐existing social, political and economic institutions to influence livelihood outcomes. These include: firm‐specific corporate strategies (including producer training); livelihood strategies of households (including access to assets); government programs; and local political economy, as manifest particularly through patronage between traders and suppliers. VSS have thereby become an additional institutional layer shaping livelihood strategies and regional development outcomes, best viewed as providing access to a new social network that may be exploited by producers. The interaction between VSS programs, livelihood strategies and pre‐existing institutional environments in a particular place often dictates the variable outcomes for producers, making attribution of impact causation to VSS enrolment problematic.

自愿性可持续标准对制度环境和生计的影响：苏门答腊南部咖啡行业的基于村庄的分析

铅焙烧公司正在通过印度尼西亚的咖啡出口商开展业务，以引入自愿性可持续性标准（VSS），以试图确保供应并同时满足企业的社会责任要求，即使实证研究继续显示出对生产者生计的不确定性收益。但是，像VSS这样的价值链干预措施并未在空白的画布上推出，许多贡献因素决定了它们对生计，特别是当地机构环境的总体影响。这项研究通过确定VSS与先前的社会，政治和经济机构互动以影响生计结果的具体过程，来评估制度环境决定经验结果变异性的程度。这些包括：公司特定的公司战略（包括生产者培训）；家庭的谋生策略（包括获得资产）；政府计划；以及当地的政治经济，尤其是通过贸易商和供应商之间的支持而体现出来​​的。因此，VSS已成为塑造民生战略和区域发展成果的附加制度层，最好被视为提供了对生产者可能利用的新社会网络的访问。VSS计划，生计策略和特定位置中先前存在的制度环境之间的相互作用通常决定了生产者的可变结果，从而使影响因果关系归因于VSS注册。以及当地的政治经济，尤其是通过贸易商和供应商之间的支持而体现出来​​的。因此，VSS已成为塑造民生战略和区域发展成果的附加制度层，最好被视为提供了对生产者可能利用的新社会网络的访问。VSS计划，生计策略和特定位置中先前存在的制度环境之间的相互作用通常决定了生产者的可变结果，从而使影响因果关系归因于VSS注册。以及当地的政治经济，尤其是通过贸易商和供应商之间的支持而体现出来​​的。因此，VSS已成为塑造民生战略和区域发展成果的附加制度层，最好被视为提供了对生产者可能利用的新社会网络的访问。VSS计划，生计策略和特定位置中先前存在的制度环境之间的相互作用通常决定了生产者的可变结果，从而使影响因果关系归因于VSS注册。最好被视为提供对可能被生产者利用的新社交网络的访问。VSS计划，生计策略和特定位置中先前存在的制度环境之间的相互作用通常决定了生产者的可变结果，从而使影响因果关系归因于VSS注册。最好被视为提供对可能被生产者利用的新社交网络的访问。VSS计划，生计策略和特定位置中先前存在的制度环境之间的相互作用通常决定了生产者的可变结果，从而使影响因果关系归因于VSS注册。
