=== Social choice theory ===
Sen's work on 'Choice of Techniques' complemented that of [[Maurice Dobb]]. In a developing country, the Dobb-Sen strategy relied on maximising investible surpluses, maintaining constant real wages and using the entire increase in labour productivity, due to technological change, to raise the rate of accumulation. In other words, workers were expected to demand no improvement in their standard of living despite having become more productive.
Sen's papers in the late 1960s and early 1970s helped develop the theory of [[social choice]], which first came to prominence in the work by the American economist [[Kenneth Arrow]]. Arrow had most famously shown that when voters have three or more distinct alternatives (options), any [[Ranked voting system|ranked order]] [[voting system]] will in at least some situations inevitably conflict with what many assume to be basic democratic norms.
