Buku Pemikiran 100 Ekonom Indonesia Edisi Kedua merupakan kumpulan tulisan para ekonom Indonesia yang diharapkan mampu memberikan kontribusi substantif, setidaknya dalam enam subjek penting dan beragam perspektif. Kontribusi substantif tersebut dibagi dalam enam bagian besar, yaitu (1) sinergi stimulus fiskal dan percepatan infrastruktur, (2) inklusi keuangan, (3) usaha mikro, kecil dan menengah (UMKM), industri dan persaingan usaha, (4) sumber daya manusia, daya saing dan kemandirian ekonomi, (5) pembangunan pertanian pedesaan, dan daerah tertinggal dan (6) tantangan mewujudkan kesejahteraan. Bagian I dari buku Pemikiran 100 ekonom ini membahas sinergi stimulus fiskal dan percepatan infrastruktur, dengan argumen bahwa pengeluaran ekstra besar untuk percepatan pembangunan infrastruktur masih senantiasa dibayangi sekian macam risiko fiskal. Bagian II membedah inklusi keuangan, karena para ekonom amat peduli pada tingkat suku bunga perbankan di Indonesia yang tercatat amat tinggi, yang tentu amat mempengaruhi akses keuangan, terutama bagi kelompok usaha kecil dan menengah. Bagian III membahas UMKM, industri dan persaingan usaha dengan berbagai spektrum. Hampir semua ekonom sepakat tentang potensi besar UMKM sebagai basis ekonomi, termasuk revitalisasi koperasi sebagai amanat konstitusi untuk memajukan kesejahteraan umum, tantangan UMKM era disrupsi teknologi dan sebagainya. Bagian IV membahas sumber daya manusia (SDM), daya saing dan kemandirian ekonomi, yang juga mendapat perhatian Pemerintah, setidaknya telah tercantum dalam rancangan teknokratik Rencana Pembangunan Jangka Menengah (RPJM) 2020-2024. Bagian V menyoroti secara khusus pembangunan pertanian perdesaan, dan daerah tertinggal, yang selama beberapa tahun terakhir masih mengandalkan intervensi negara melalui APBN dan terlalu fokus pada program swasembada pajale (padi-jagung-kedelai). Bagian VI atau terakhir membahas beberapa perspektif penting dan tantangan strategis dalam mewujudkan kesejahteraan umum. Para ekonom cukup prihatin terhadap lambannya penurunan kemiskinan dan ketimpangan pendapatan, walaupun kinerja pertumbuhan ekonomi masih di atas 5 persen per tahun.

Numerous studies have examined modern supply chains particularly agribusiness firms in the agrifood transformation, but how the transformation excludes or includes growers and how social factors, particularly relationship quality, influence growers to participate are limited to be investigated. Focusing on Indonesian potato producers, this thesis addresses the literature in five essential ways. Firstly, most current studies use farmers' capacity and demography variables, but pay less attention to the social capital contributing to farmers' participation. Secondly, few studies utilize per capita income to analyze the impact of farmers' participation in modern supply chains. Thirdly, numerous studies examine the ex post perspective of potato farmers' motives to contract with modern supply chains; however, ex ante motives are seldom highlighted. Fourthly, the topic of relationship quality in relational marketing with buyers in the emerging markets has received little attention. Finally, limited research draws attention to women's roles in emerging markets and the gender differences related to agribusiness relational marketing. This thesis addresses how the potato producers make marketing decisions and interact with their buyers and what influences them to engage in the modern supply chains to improve their business performance. The specific research objectives are to investigate: (1) the factors influencing farmers' participation in the modern supply chains and the impacts of contract farming with the modern supply chain on the potato farmers' income; (2) the motivations for the potato farmers to engage in contracting; (3) the determinants of trust as a construct of relationship quality within the groups of potato farmers; and (4) the differences of relationship quality factors between males and females. A farmers' participation model was developed. It includes socio-demographics, contextual characteristics, farm capacity, and incentives as determinant factors involved in the emerging markets. Furthermore, the farmers' participation is associated with an increased per capita income. The analysis from an ex ante perspective of farmers engaging in contracts shows four factors influencing farmers' motivations: (1) market uncertainty; (2) direct benefits; (3) economic motive; and (4) intangible benefits. The research demonstrates the determinants of relationship quality between three groups of potato producers and buyers including communication, flexibility, dependence, and joint problem solving. In addition, this study finds relational variables which differ between male and female farmers among the groups i.e. communication, reputation, joint problem solving, price fairness, uncertainty, performance and organizational culture. Although the females' roles in production and marketing are significant, the females tend to rate the relational factors lower than the males. The results of this study have crucial implications on how to enhance smallholders' participation in modern supply chains. The results confirm that integrating smallholders should be promoted as a strategic policy for assisting farmers to raise income. Developing and establishing relational quality between farmers and their buyers will create efficiency in marketing as it reduces transactions costs. Agribusiness firms or retailers need to maintain and improve the quality of their relationships with potato farmers. The government should pay attention to production and market infrastructure, and access to production inputs and credits through increasing national budget for agricultural infrastructure and development to support small farmers' entrance into modern supply chains.
