Publisher Connection: Export-Led Growth in the UAE: Multivariate Causality Between Primary Exports, Manufactured Exports and Economic Growth

The principal question that this research addresses is the validity of the Export-Led Growth hypothesis (ELG) in the United Arab Emirates (UAE) over the period 1981–2012, focusing on the causality between primary exports, manufactured exports and economic growth. Unit root tests are applied to examine the time-series properties of the variables, while the Johansen cointegration test is performed to confirm or not the existence of a long-run relationship between the variables. Moreover, the multivariate Granger causality test and a modified version of Wald test are applied to examine the direction of the short-run and long-run causality respectively. The cointegration analysis reveals that manufactured exports contribute more to economic growth than primary exports in the long-run. In addition, this research provides evidence to support a bi-directional causality between manufactured exports and economic growth in the short-run, while the Growth-Led Exports (GLE) hypothesis is valid in the long-run for UAE

Sraffians, other post-Keynesians, and the controversy over centres of gravitation

International audienceOver the last two decades, a number of Post-Keynesian methodologists have wondered whether the Sraffian school ought to be kept under the Post-Keynesian umbrella, many of them answering that indeed Sraffians ought to be ejected from the Post-Keynesian school if post-Keynesianism were to be methodologically coherent. This has been the position of, among others, Dow (1988), Gerrard (1989), Pratten (1996), Walters and Young (1997) and Dunn (2000, 2008). Stephen Dunn (2000, p. 350) claims that even Sraffians favourable to the project of keeping the Keynesian and Sraffian strands of Post-Keynesianism together have given up, writing that ‘Roncaglia (1995) has called for the abandonment of the project to integrate Sraffian and Post-Keynesian analysis’. Sheila Dow (2001, p. 18) makes an identical attribution, saying that ‘it has even been suggested that attempts to identify the Sraffian approach with Post Keynesianism should be discontinued’, citing the same Roncaglia (1995) paper in support of her claim
