First comes the labour of love; the endless stream of lectures, articles, internet-searches, conversa- tions and seminar presentations; the beer-soaked late-night dialogues reconciling venerable frameworks with what one fondly hopes are fresh insights. Then comes the miracle of compression; the stripping away of the inessential, the concentration of four years of rela- tively free-ranging thought into a handful of short chapters that are expected to bear some linear relation to one another.
Often the latter exercise obliterates all traces of the former. The complex influence of all the people without whom one’s dissertation would not have been started, sustained or completed is quite obscured behind the inscrutable theorems and cursory literature reviews. Luckily prefaces were invented to redress the balance - to remember, to recount, and above all, to give thanks. I was extremely fortunate in my choice of advisors.
David Weil walked me through the maze of graduate economics with Socratic forbearance and an unerring ability to tell the escape route from the blind alley. Oded Galor taught a course in growth theory so superb that it made my choice of specialization easy. Tony Lancaster gave me the confidence to embark on independent research by co-authoring a paper with me in my second year, and by reminding me that Time’s Winged Charriot Hurries Near. Several professors at Brown University commented on the papers that I wrote.
Peter Howitt encouraged me greatly by always being available to discuss ideas old and new. I received much guidance from John Driscoll, Pravin Krishna and Andrew Foster. My second summer in graduate school was spent at the IMF, where Chris Towe and Patricia Reynolds, with unusual kindness, put me to work on an independent project connected with vũ my research interests. My third summer was spent working in New Delhi with Surjit Bhalla, who taught me the practical value of triple-checking one’s data-set for inconsistencies before even thinking of running regressions.
From my friends and colleagues in the department I learned more than any book has ever taught me. Brown University enjoys considerable economies of scale in the large number of aspiring growth theorists that it produces; of these economies I was a grate- ful beneficiary. Areendam Chanda, Kyung-Mook Lim, Len Erickson, Seiro Ite, Azam Chaudhry, Phil Garner and several others conspired to make lunch in the Blue Room a source of intellectual inspiration. Jim Feyrer and Carl-Johan Dalgaard went a step further and wrote considerable bits of my dissertation for me.
My thanks must also wing their way to my families, who have supported me through thick and thin, wherever in the world I have found myself and however limitless my time in school has seemed to grow. Papa, Mum, Naiyya, Shahnaz, Gang: to you I owe far more than this Ph. Franziska Ohnsorge was force-fed early drafts of all my papers, each of which she was able to improve with casual ease. It is remotely possible that this dissertation would have heen written without her.
But in her absence its writing may not have seemed as worthwhile, nor my years in graduate school as enjoyable.

This paper argues that the dichotomy is spurious, resting on a conflation of the proximate determinants of income variation with the ultimate determinants of the same. Two important recent contributions to the debate are Klenow and Rodriguez-Clare (1997) and Hall and Jones (1999).
