On the limitations of armchair economics: Some views of an armchair agricultural economist
讨论了扶手椅经济学在解释和预测总体现象方面的局限性，指出由于复杂理论的模糊性和实证估计中的补偿性错误，其局限性可能比主流经济学界普遍承认的更严重。
A large portion of economists' activities can be labelled armchair economics. In this paper the limitations of armchair economics with respect to explaining and predicting aggregate phenomena are discussed. It is argued that, due to ambiguity of sophisticated theory and compensating errors in empirical estimations, armchair economics is likely to face more serious limitations than is generally acknowledged by the mainstream of the profession.
