Title: Some new views on product space and related diversification
Abstract: We aim to contribute to the literature on product space and
	 diversification by proposing a number of extensions of the current
	 literature: (1) we propose that the alternative but related idea of a
	 country space also has empirical and theoretical appeal; (2) we argue
	 that the loss of comparative advantage should be an integral part of
	 (testing the empirical relevance of) the product space idea; (3) we
	 propose several new indicators for measuring relatedness in the product
	 space; and (4) we propose a non-parametric statistical test based on
	 bootstrapping to test the empirical relevance of the product space idea.
