i thought allocative efficiency occurs when the interplay of market forces govern resource allocation, resulting in a more efficient allocation of resources.
technical efficiency arises as a result of firms decreasing production costs, either through improving the productivity of labour, or through technology.
dynamic efficiecny occurs when firms are able to adapt to changes in teh external or internal economic environment. e.g., the fact that Australia has sustained economic growth of 3.8% despite world growth contracting to 1.7% reflects the increased dynamic efficiency of Australian firms.
