Veblen's evolutionary programme: a promise unfulfilled
详细考察凡勃伦如何试图为其1898年论文中提出的演化经济学纲领赋予理论形式，指出其基于达尔文方法论构建的纯粹因果性制度演化理论未能令人满意地发展，最终成为一个未实现的承诺。
This article examines in detail the way in which Veblen attempted to give theoretical expression to the programme for an evolutionary economics that he outlined in methodological terms in his 1898 essay ‘Why is Economics Not an Evolutionary Science?’ Veblen's conception of ‘Darwinian’ methodological principles led him to attempt to develop a theory of institutional evolution that was purely ‘causal’ in nature. This theory was never satisfactorily developed by Veblen. At base, his theory was one of new technology changing economic conditions, and new economic conditions leading to new ways of thinking and to new institutions through a (non-intentional) process of ‘habituation’. Those who attempted to follow Veblen, such as Hoxie and Mitchell, found difficulties with the key aspects of this theory, and both men came to abandon it. Institutionalism in the interwar period is devoid of attempts to develop Veblen's theory, and Veblen's programme remained a promise unfulfilled.
