On Government-industry Nexus and Indigenous Armed Resistance

This paper proposes a simple game-theoretic framework for analyzing the relationship between the government, industry and indigenous community, especially in the context of mounting violence surrounding displacement of indigenous communities by governments for the purposes of commercial use of their habitat. It specifically takes into account the possibility of alleged ‘nexus’ between the government and the industry and explores its implications on the level of allocation and utilities of the players. We find that the bias in allocation that occurs when the government and the industry enter a ‘nexus’ can be rectified when there is resistance from the indigenous groups. Moreover, rebellion is a dominant strategy of the indigenous community, irrespective of whether there is ‘nexus’ or not, and being in ‘nexus’ with the government is a best response for the industry. The unique SPNE occurs when there is ‘nexus’ between the industry and the government and resistance by the indigenous groups, corroborating the widespread allegations of ‘nexus’ and evidence of resistance worldwide. We also explore a few extensions of the basic model and present some narrative evidence in support of the theoretical model.     

Military Off the Shelf Procurements: A Norwegian Case Study

Buying off the shelf procurements (OTS) has become an important part of the national acquisition strategy in several countries, and this paper seeks to bring empirical evidence on OTS as the preferred acquisition strategy by use of data from 2015 to 2022 investment portfolio of the Norwegian Armed Forces. We develop definitions for three categories of procurement – OTS, modified OTS and development projects – as well as a method to classify projects into these categories. Our first finding is that the characteristics of OTS projects correspond to modified OTS and development projects. Our second finding indicates that OTS projects perform better when it comes to the completion of projects according to the initial schedule, compared to development projects.
