‘This tendency to Diminishing Returns was the cause of Abraham’s parting from Lot, and of most of the migrations of which history tells’ wrote the founder of neo-classical economics, Alfred Marshall, in the first edition of his textbook Principles of Economics (1890). In a footnote he refers to the Bible’s Genesis xiii : 6: ‘And the land was not able to bear them that they might dwell together; for their substance was great so they could not dwell together’. (Marshall 1890: 201)
Marshall’s observation also applies to today’s migration patterns: from countries where most activities are subject to constant or diminishing returns to countries whose key economic activities are subject to increasing returns to scale. Diminishing returns occur when one factor of production is limited by nature, which means that it occurs in agriculture, mining, and fisheries. Normally the best land, the best ore, and the richest fishing grounds are exploited first, and – after a point – the more a country specialises in these activities, the poorer it gets. OECD (2018) shows how this occurs in Chilean copper mining: every ton of copper is produced with a higher cost than the previous ton.
In Alfred Marshall’s theory, the ‘Law of Diminishing Returns’ is juxtaposed with ‘The Law of Increasing Returns’, also called economies of scale. Here we find the opposite phenomenon; the larger the volume of production, the cheaper the next unit of production becomes. Traditionally economies of scale were mainly found in manufacturing industry, and increasing returns combined with technological change has for centuries been the main driving force of economic growth. Increasing returns creates imperfect competition, market power and large barriers to entry for challengers – companies or nations – making it difficult for them to enter these industries. In contrast to the rents produced under conditions of increasing returns, raw materials – commodities – on the other hand, are subject to perfect markets, and productivity improvements spread as lowered prices. This is the essence of the theory which explains why former World Bank Chief Economist Justin Yifu Lin was correct hen he asserted that ‘Except for a few oil-exporting countries, no countries have ever gotten rich without industrialization first’ (Lin 2012 : 350).Read More »
In his report on the Minimum Core Doctrine (MCD) John Tasioulas states:
“the essence of the concept will be taken to be the sub-set of obligations associated with socio-economic rights that must be immediately complied with in full (obligations of immediate effect)” (p. 3).
He contrasts these against those obligations that require significant resources and are therefore subject to ‘progressive realization’. Thus, the defining characteristic of MCD is that it differentiates obligations between those of immediate effect and those of progressive realization. And the focus is on the nature of the obligations (what the state must do when) rather than the nature of substantive rights (the condition of people’s lives).
However, the discussion about what constitutes minimum core obligations in substance focuses on the nature of rights enjoyment and a package of minimum goods and services that would be required rather than the nature of obligations. This starts with General Comment 3 that refers to ‘a minimum core obligation to ensure the satisfaction of, at the very least, minimum essential levels of each of the rights’, and to the provision of ‘essential primary health care’ (ICESCR quoted in Tasioulas p. 5). Further, human rights-based practice begins to specify specific types of diseases to be treated and goods and services that would be included in the minimum, as under the ‘selective primary health care model’ adopted by UNICEF (Tasioulas p. 5).Read More »
The theme of the 2018 World Economic Forum was, “Creating a Shared Future in a Fractured World.” Its six richest attendees each boasted an estimated net worth of $5.2 billion or more, or the same amount as the total burden of Somalia’s outstanding debt, which, amid the splendor of the event, Somali Prime Minister Hassan Ali Khayre met with IMF Managing Director Christine Lagarde to discuss clearing. In this era of extreme global inequality, it is estimated that the United Nations agenda of seventeen sustainable development goals (SDGs) known as Agenda 2030, will require 4.5 trillion dollars of investment per year to be realized, or more than twice the amount expected to be available from traditional official development assistance (ODA) alone. Due to the increasing concentration of private wealth in the global economy, discussions around development finance have focused on private sector engagement, rather than more traditional, ODA from predominantly Western donor governments and multilateral institutions.Read More »
This July and August, I led an international group of experts in preparing an Economic Report on the role of the BRICS countries (Brazil, China, India, Russia and South Africa) in the world economy and international development. The Report was commissioned as an input to the Summit of BRICS countries that took place in early September 2017 in Xiamen, China.
It surveys the BRICS countries’ sizable contribution to global growth, trade and investment, evaluates the prospects for this to continue in the future, and explores the possible role that these countries can play in bolstering the global economy, in reshaping international economic arrangements and in contributing to the Sustainable Development Goals and to international development generally. An important conclusion in the report is that continued BRICS growth as well as policy initiatives can substantially benefit other developing countries (the report uses the IMF category of Emerging Market and Developing Countries, or EMDCs) – and developed countries too. I will be pleased if the report will be circulated widely, and welcome all reactions.Read More »
