Purpose This article emphasises the role of constraints when humans establish organisations. Previous research explains organisations because of individuals’ motivations.

Balancing Different Goals: How An NGO Struggles to ‘Implement’Empowerment

S Combes, D Kardiana, E Le Grand Available at SSRN 4255178, 2022

NGOs claim they are against the State. However, this is challenged in the literature. Here, we attempt to show that the micro activity of an NGOs is torn between two views about the NGO. On one side, the view that the NGO has some production that is quantified, time limited, bounded in terms of activities....

This article questions the elephant in the room of Cost-Benefit Analysis: the costs. From the 1970s onward, most, if not all, the research has focused on the measurement of benefits, this led to different techniques used to allocate resources. To try to respond to this issue we use a macroeconomic framework to propose a new...

Beyond budget constraints, a new constraint measure based on resources, with an application to Health Technology Assessment

S Combes, F Becker With an Application to Health Technology Assessment (January 30, 2022), 2022

In Health Technology Assessment (HTA), commonly used techniques apply piecewise comparisons of two or more alternatives, comparing costs and outcomes associated with each treatment. According to the definition by Robbins, who considers economics the study of ‘alternative uses’ of resources (Robbins, 1984, 1932), HTA can be considered a branch of health economics. However, we argue...
