英文摘要：
  We propose a combinatorial model of economic development. An economy develops by acquiring new capabilities allowing for the production of an ever greater variety of products of increasingly complex products. Taking into account that economies abandon the least complex products as they develop over time, we show that variety first increases and then decreases in the course of economic development. This is consistent with the empirical pattern known as \'the hump\'. Our results question the common association of variety with complexity. We further discuss the implications of our model for future research.

中文摘要：
我们提出了一个经济发展的组合模型。一个经济体通过获得新的能力来发展，从而能够生产越来越复杂的产品和越来越多种类的产品。考虑到经济体在发展过程中会放弃最不复杂的产品，我们表明，在经济发展过程中，多样性首先增加，然后减少。这与被称为“驼峰”的经验模式是一致的。我们的结果对多样性与复杂性的共同联系提出了质疑。我们进一步讨论了我们的模型对未来研究的影响。
