    • Economic performance and capacity utilisation in vietnamese purse seine fishery 

      Cao, Thi Hong Nga; Eide, Arne; Armstrong, Claire W.; Long, Le Kim (Journal article; Tidsskriftartikkel; Peer reviewed, 2020)
      This study identifies differences in vessel efficiency amongst purse seiners in Vietnamese fishery. Deterministic data envelopment analysis (DEA) was used to assess relative capacity utilisation of each vessel, and double bootstrap DEA was adopted to overcome some of the drawbacks of nonparametric DEA. The study was based on a survey of costs and earnings from 52 purse seiners in 2016, revealing ...

    • Economic performance, technical efficiency and fishers’ perceptions of factors affecting fishing activities. A study of a Vietnamese purse seine fleet 

      Cao, Thi Hong Nga (Doctoral thesis; Doktorgradsavhandling, 2022-12-19)
      <p>The focus of this thesis is on the economic performance and technical efficiency of a Vietnamese fishing fleet by the use of data envelopment analysis (DEA). The double bootstrap method has been used to overcome some of the limitations of DEA. In addition, the dissertation evaluates fishers’ perceptions of negative events affecting the fishing activities. <p>The first of three papers presents ...

    • Measuring capacity utilization in fisheries using physical or economic variables: A data envelope analysis of a Vietnamese purse seine fishery 

      Cao, Thi Hong Nga; Eide, Arne; Armstrong, Claire W.; Long, Le Kim (Journal article; Tidsskriftartikkel; Peer reviewed, 2021-07-26)
      Data Envelopment Analysis (DEA) studies of fisheries usually apply output oriented capacity utilization based on physical measures. Although physical measures capture important input factors employed in fishing activities (such as boat size, engine power), economic measures directly reflect the cost of inputs employed. This case study investigates whether economic measures are vital or whether ...

    • A study on the economic efficiency of the offshore long line fishery in Khanh Hoa province, Vietnam 

      Cao, Thi Hong Nga (Master thesis; Mastergradsoppgave, 2010-05-17)
      Since the 1990s, Vietnam’s government has made great efforts to develop the offshore fisheries development program. Study on the economic efficiency of the offshore long-line fishery is needed to evaluate and improve the program’s effectiveness. This thesis presents findings based on survey data collected through a representative sample of 37 registered offshore vessels operating in the Vietnam’s ...
