One of the most striking changes in economic, thinking which comes primarily with John Maynard Keynes, is his explicit focus on time. For example, it appears early in a part of Keynes's writings that prediction is a very difficult matter. Due to the near impossibility of prediction of the future, uncertainty is a central theme relatively early of Keynes's economic thinking. This theme regarding prediction also implies that Keynes makes a clear distinction between short- and long-term expectations. Theory was to be concerned mainly with the present and with short period situations and the explicit attention to the concept of time, and subsequent alternative method of analysis has led to a number of innovations in economic thinking. This paper will address Keynes's handling of the concept of time from three angles: studying his philosophical background, his understanding of society, and his development of economic theory. 展开更多
