We consider the situation in which a purchaser can either buy a large quantity at the same time or sequentially in a number of smaller lots. Buying in a number of smaller lots obviously increases transaction costs. But buying in smaller lots provides the opportunity to the supplier to learn by discovering the true costs of supplying every lot. This is especially interesting for purchasers (and ...

In particular, consequentialist decisions such as sacrificing one life to save an even greater number of lives can lead to unfavorable character evaluations, even when they are viewed as the preferred course of action.

1.3. There is increasing recognition, however, that smaller business customers, and in particular sole traders and micro businesses, are likely to face many of the same problems as individual consumers when making purchasing decisions, especially for purchases that are not directly linked to their particular trade.
