According to Ogihara (1995), the usage of the embedded present in a speech report such as John said that Mary is in the room is restricted by the cause of John’s belief (the state that made John think that Mary is in the room): the present tense can be used only if this cause still holds at the time that John said that Mary is in the room is uttered.
This paper presents experimental evidence demonstrating that this is only one of the factors that licenses a felicitous usage of the embedded present tense. In particular, we show that the cause of belief still holding is not a necessary condition, and identify two additional, sufficient (but not necessary) factors: in cases of false belief, who is aware of the falsity of the belief and duration of the reported state. While these factors are independent, they collectively support the idea that the present tense encodes ‘current relevance’, even in embedded contexts (e.g. Costa 1972; McGilvray 1974). This gives rise to the question of how we can derive ‘current relevance’ and, in particular, whether previous analyses of the embedded present tense are adequately equipped to do so.
Money is more than memory
(2014)
Impersonal exchange is the hallmark of an advanced society. One key institution for impersonal exchange is money, which economic theory considers just a primitive arrangement for monitoring past conduct in society. If so, then a public record of past actions — or memory — supersedes the function performed by money. This intriguing theoretical postulate remains untested. In an experiment, we show that the suggested functional equality between money and memory does not translate into an empirical equivalence. Monetary systems perform a richer set of functions than just revealing past behaviors, which proves to be crucial in promoting large-scale cooperation.
