This paper proposes a new heuristic for solving the economic lot scheduling problem in flow shops under the Power-of-Two policy. A review of relevant literature shows that the heuristic in Ouenniche and Boctor [15] not only solves this problem with the best objective function value among the existing solution approaches, but also generates a feasible production schedule. However there are sever...

Revealed preference tests are elegant nonparametric tools that ask whether individual or aggregate data conform to economic models of optimizing behavior. In designing a test using revealed preference, however, one faces a vexing tension between goodness-of-…t and power. If the test …nds violations, then one must ask if the test was too demanding— is there an acceptable tolerance for goodness-o...

This paper presents a two-agent economy, in which each agent has a consumption-dependent time preference. The optimal dynamic paths of accumulation will tend to one of many possible steady states, depending on the location of the initial capital level. One of the main results of this model arises in comparison with single-agent models. More precisely, one possible instance of the model consists...
