The paper presents the topic modeling technique known as Latent Dirichlet Allocation (LDA), a form of text-mining aiming at discovering the hidden (latent) thematic structure in large archives of documents. By applying LDA to the full text of the economics articles stored in the JSTOR database, we show how to construct a map of the discipline over time, and illustrate the potentialities of the technique for the study of the shifting structure of economics in a time of (possible) fragmentation.
There is considerable discussion on so-called 'mainstream pluralism' , that is, on the co-presence of a variety of research programmes in today's mainstream economics that: 1. significantly deviate from the neoclassical core; 2. are pursued by different, often separate communities of researchers; 3. have their origins outside economics. The literature tends to regard mainstream pluralism as a transitory state towards a new, post-neoclassical, mainstream. This paper advances a new interpretation: it suggests that the changing and fragmented state of mainstream economics is likely to persist over time under the impact of specialization (as a self-reinforcing mechanism) and the creation of new specialties and approaches, also through collaboration with researchers from other disciplines.
Th e paper aims at showing that revisiting Keynes's early writings on international economic relations and some less well-known episodes of his economic diplomacy, with special attention being paid to the methodological issues involved, may disclose useful insights in understanding the features of his desired new global order. We contrast the three main pillars of Keynes's vision as detected in this revisitation (coordinated multilateral responses to global imbalances, a rational international monetary regime, and enhanced policy space) with the major shortcomings of the current non-system, and show the continuing relevance not only of Keynes's specifi c proposals for global reform, but also, and most importantly, the legacy of his way of reasoning about international economic relations.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
