In some cases of insurgency, the combat frontier is contested and erratic, as rebels target cities as their economic prey. In other cases, it is tidy and stable, seemingly representing an equilibrium in which cities are effectively protected from violent non-state actors. What factors account for these differences in the interface urban-based states and rural-based challengers? To explore this question, this book examines two regions representing two dramatically different outcomes. In West Africa (Liberia and Sierra Leone), capital cities became economic targets for rebels, who posed dire threats to the survival of the state. In Maoist India, despite an insurgent ideology aiming to overthrow the state via a strategy of progressive city capture, the combat frontier effectively firewalls cities from Maoist violence. This book argues that trade networks underpinning the economic relationship between rural and urban areas—termed “interstitial economies”—may differ dramatically in their impact on (and response to) the combat frontier. It explains rebel predatory tendencies toward cities as a function of transport networks allowing monopoly profits to be made by urban-based traders. It explains combat frontier delineation as a function of the social structure of the trade networks: hierarchical networks permit elite–elite bargains that cohere the frontier. These factors represent what might be termed respectively the “hardware” and “software” of the rural–urban economic relationship. Of interest to any student of political economy and violence, this book presents new arguments and insights about the relationships between violence and the economy, predation and production, core and periphery.

Attachment Mechanism

AbstractFailing to consider the strong correlations between weights and topological properties in capacity-weighted networks renders test results on the scale-free property unreliable. According to the preferential attachment mechanism, existing high-degree nodes normally attract new nodes. However, in capacity-weighted networks, the weights of existing edges increase as the network grows. We propose an optimized simplification method and apply it to international trade networks. Our study covers more than 1200 product categories annually from 1995 to 2018. We find that, on average, 38%, 38% and 69% of product networks in export, import and total trade are scale-free. Furthermore, the scale-free characteristics differ depending on the technology. Counter to expectations, the exports of high-technology products are distributed worldwide rather than concentrated in a few developed countries. Our research extends the scale-free exploration of capacity-weighted networks and demonstrates that choosing appropriate filtering methods can clarify the properties of complex networks.

This study used social network analysis, which is often adopted to analyze changes in trade structures and the world trade network for faux fur products, which are alternative materials used in vegan fashion. The data on the total trade value of artificial fur (HS Code: 4304) and animal fur and leather (HS Code: 0505) imports and exports between countries were collected through UN Comtrade, and the degree and betweenness centralities were used to analyze the trade structure of faux fur in 2009, 2014, and 2019 using NodeXL 1.0.1 programs. The results of the study are as follows: First, while the total amount of export and import of faux fur is increasing globally every day, the total amount of export and import in other Asian countries and Vietnam is decreasing. Second, due to the reduction in exports of the main producing countries of animal materials such as China, global imports of animal fur and leather decreased. Third, China was the largest ex-porter of faux fur, exporting to a large number of countries; it also played an important role in the intermediation and control over faux fur export. In exporting faux fur, the influence of other Asian countries declined over time, and Vietnam and the United States played an outstanding role as arbitrators in the export network. Fourth, Italy and France were the largest importers of faux fur from various countries and exerted significant influence as intermediaries in the import network of faux fur. On the other hand, Vietnam’s influence in import network decreased. Saudi Arabia appeared to be an important arbitrator in mediating the import. This study is significant due to its findings, obtained through micro-trading data, in respect of industrial moves of ethical fashion in the form of increased trade in faux fur and decline in the trade of animal fur and leather.

The article discusses the ways in which, in the seventeenth century, as India drew the attention of more Europeans, both as private traders and as part of larger east India companies, networks of contacts were established. Two ports in particular, Surat and Madras (now Chennai), became points of intersection of Europeans and Asians, through the multi-pronged trade networks that linked these two ports to other ports in the Indian Ocean world, through traders from across regions. Focus is on the English in particular, as their main port of trade for Mughal North India was Surat, and Madras, their first fortified establishment on the coast of India.
