International Trade and the Value of Time

I discuss a generalized Heckscher–Ohlin–Vanek (HOV) model in which consumption requires time as well as money (as in Becker's theory of the allocation of time) and the amount of work that a worker can do per unit of time—her “ability”—varies from country to country. High ability implies high income per hour, which implies a high value of time and, therefore, high consumption of the good that is more “time‐saving.” Therefore, if domestic production of this good is not commensurately high, it would have to be imported. In this way, I demonstrate that international differences in worker ability constitute an independent source of gains from trade. The model is able to explain several observed features of North–South trade that are not explained by the HOV model. The theoretical possibility of a Leontief paradox‐type trade pattern is also demonstrated.
