Untangling the Benefits of Protected Areas in Fisheries

Studies of marine protected areas as a tool for fisheries management have shown that protected areas have the potential to improve the level of resource rent generated in the fishery. The benefits to the fishery from protected areas have been shown to increase with sub-optimal management. However, some benefit that is derived from protected area creation in these circumstances is attributed to changes in effort levels. Both unique benefits, such as the hedge benefits of protected area creation, and non-unique benefits, such as shifts in effort levels towards optimal levels, are explored. Examples are taken from analysis of protected area creation in a predator-prey meta-population fishery under several different scenarios. It is suggested that much of the gain from protected area creation under sub-optimal management can be attributed to non-unique benefits, with the policy implications of this analysis also explored.Bioeconomics, fisheries management, marine protected areas, Environmental Economics and Policy, Q22,

Bioeconomic analysis of protected area use in fisheries management

Protected areas in fishery management have been suggested to hedge management failures and variation in harvests. In this paper, a stochastic bioeconomic model of a two-species fishery in the Manning Bioregion is used to test the performance of protected areas as a management tool in a fishery. The establishment of a protected area is analysed under the assumption of heterogenous environments that are linked via density-dependent or sink-source stock dispersal relationships. The sensitivity of the results to different degrees of management is also explored. The model is applied to the Ocean Prawn Trawl, and Ocean Trap and Line fisheries within Manning Bioregion in New South Wales, Australia. The focus of the study is placed on the biological and institutional characteristics that yield benefits to the fishery. It was found that protected area use in the Manning Bioregion is likely to have differing effects on the two fisheries examined, benefiting Ocean Trap and Line fishers but adversely affecting Ocean Prawn Trawl fishers. Overall, it is unlikely that protected area use will lead to an increase resource rent in the fishery.bioeconomics, fisheries management, marine protected areas, Resource /Energy Economics and Policy,

Tariffs and Steel: The US Safeguard Actions

This paper presents a multi-product price linked spatial equilibrium model of world steel trade. The model is used to analyse the impacts of the safeguard trade barriers brought about by the United States in order to protect their domestic industry from so called unfair competition. Emphasis is placed on the likely effect to the Australian industry and possible policy responses available to the industry. A case study is made on Australia's three largest export products, namely slab, hot-rolled and cold-rolled steel, which share some substitutability in supply and demand due to the nature of the industry.trade, spatial equilibrium model, steel, International Relations/Trade,

Tariffs and steel: US safeguard actions

A multiproduct spatial equilibrium model of world steel trade is presented in this paper. The model is used to analyse the impacts of the safeguard trade barriers brought about by the USA in order to protect their domestic industry from the so-called unfair competition. Emphasis is placed on the likely effect on the Australian industry and possible policy responses available to the industry. A case study is made of Australia’s three largest export products; namely, slab, hot-rolled and cold-rolled steel, which share some substitutability in supply and demand because of the nature of the industry. As a result of the safeguard barriers to steel trade, world steel prices fell and trade shifted away from the USA to other importing regions.spatial equilibrium model, steel, trade, International Relations/Trade,
