In the short run, both average total cost (ATC) and marginal cost (MC) will increase. Based on the law of diminishing marginal returns, when products expand, the return of per unit product is decreasing. On the on the other hand both MC and ATC are increasing. The examples in this case are The nature of the problems which can arise from this can be seen in the case of the increase in the cost of bananas associated with Cyclone Larry.
