This article tries to disaggregate the changes in South Africa’s rugby ideology during and after the Rugby World Cup tournament of 1995. The nature of support for the victorious Springbok team which in a rare historical moment seemed to transcend race, is explained in the light of contextual influences. Likewise, the significance of subsequent events till the middle of 1997 which appeared to co...
Political reconciliation involves the repairing of damaged political relationships. This paper considers the possibility and moral justifiability of pursuing political reconciliation in the aftermath of systematic and egregious wrongdoing, in particular genocide. The first two sections discuss what political reconciliation specifically requires. I argue that it neither entails nor necessitates ...
A [Ir(ppy)2(dtb-bpy)]PF6-catalyzed intramolecular radical cyclization of o-iodophenylacrylamides affording indolin-2-ones in moderate to excellent yields via 5-exo-trig radical cyclization under visible light is presented. This method provides new access to the synthesis of indolin-2-ones under mild reaction conditions.
This paper investigates the nature of U.S. fiscal policy in the aftermath of 9/11. We argue that the recent dramatic fall in the government surplus and the large fall in tax rates cannot be accounted for by either the state of the U.S. economy as of 9/11 or as the typical response of fiscal policy to a large exogenous rise in military expenditures. Our evidence suggests that, had tax rates resp...
Prior to the 2007–2008 financial crisis, banking sector profits were very high but the profitability of financial intermediation was poor. Using a novel model of banking, this article argues that the high profits were achieved through balance sheet expansion and growing default, liquidity, and term risk mismatches between assets and liabilities. As a result, large banks’ financial leverage rose...
This paper presents new evidence that immigrants have better health than natives upon arrival to their destination. It analyzes a very interesting episode in international migration, namely the exodus of Ecuadorians in the aftermath of the economic collapse in the late 1990s. More than 600,000 Ecuadorians from 1999 to 2005 left their homeland, most relocating in Spain. Using information from th...
