„State support remains a leading cause of tension in international commercial relations. Governments can see trade distortions that look like they were caused by industrial subsidies, but they lack the data to illuminate that state support. In the 1980s at the height of the farm wars the Organisation for Economic Co-operation and Development (OECD) developed an index that helped countries to see the overall incidence of agricultural subsidies, initially called the Producer Subsidy Equivalent (PSE) and the Consumer Subsidy Equivalent (CSE). Are there lessons for today in the PSE approach? This paper tries to answer that question from the standpoint of economics: how did the PSE evolve, what is it, is the concept relevant to industrial subsidies? And of politics: how was OECD able to create the tool, and do present conditions permit something similar? The brief answer is that the PSE was a response to a shared perception of crisis, but it was pushed by finance not trade or agriculture ministers. It drew on well-established concepts in the agricultural economics and trade literatures. And it works best in a context where market power is sufficiently diffuse that a price gap between domestic and world prices can be calculated. Only some of those conditions can be met when applying the approach to concentrated industries dominated by large firms that operate in multi-country supply chains.“
