    • “All along the curves”: Bridging the gap between comparative statics and simultaneous econometric models 

      Brækkan, Eivind Hestvik; Myrland, Øystein (Journal article; Tidsskriftartikkel; Peer reviewed, 2019-10-31)
      A simultaneous econometric model of supply and demand provides estimates of own-price effects and the effect of exogenous variables on supply or demand. Most of the time economists use elasticities derived from econometric analysis in a ceteris paribus context, more seldom in a total elasticity setting (Buse in J Farm Econ 40:881–891, 1958). Perhaps even more seldom net effects of exogenous changes ...

    • Asymmetric price transmission in a changing food supply chain 

      Kidane, Dejene Gizaw; Myrland, Øystein; Xie, Jinghua (Journal article; Tidsskriftartikkel; Peer reviewed, 2020-08-26)
      The farmed salmon supply chain in Europe is changing. There is a growing concentration at intermediary levels in the supply chain and more product differentiation in the market. This means that different price determination processes could apply in various product sub-markets. In this study, price transmission relationships in the salmon value chain were investigated at two different product levels. ...

    • Consumer preference for fish safety inspection in Bangladesh 

      Hoque, Mohammed Ziaul; Myrland, Øystein (Journal article; Tidsskriftartikkel; Peer reviewed, 2022-01-13)
      Consumers are entitled to eat safe food, so authorities should ensure that this right is preserved by enacting regulations and ensuring compliance through enforcement activities. Safety inspection is key to the enforcement system. Therefore, this paper presents an analysis of consumer responses to a regulatory scheme for safe seafood. The regulations consist of national and local authority enforcement ...

    • The demands they are a-changin' 

      Brækkan, Eivind Hestvik; Thyholdt, Sverre Braathen; Asche, Frank; Myrland, Øystein (Journal article; Tidsskriftartikkel; Peer reviewed, 2018-03-15)
      Smooth operators such as time trends are often applied to deal with unidentified demand shifters. However, if unknown factors affect demand irregularly, a time trend fails to capture the variation. We present an index approach for estimating irregular demand shifts, decomposing total demand shifts into predicted and unexplained effects. This allows separating demand shifts caused by known factors ...

    • Determinants of trip duration for international tourists in Norway; a parametric survival analysis 

      Alizadeh Ashrafi, Tannaz; Myrland, Øystein (Journal article; Tidsskriftartikkel; Peer reviewed, 2017-10-10)
      How long a tourist stays in a host country acts as an indicator of tourism industry’s contribution towards the national economy. The purpose of this study is to examine how socio-demographic characteristics of international tourists, their travelling purpose, tourism products and characteristics of the destination influence the length of stay in Norway, by estimating a parametric survival model. ...

    • Effects of ‘doctor shopping’ behaviour on prescription of addictive drugs in Sweden 

      Zykova, Yana; Mannberg, Andrea; Myrland, Øystein (Journal article; Tidsskriftartikkel; Peer reviewed, 2022-01-22)
      Free choice of health care providers is aimed to improve the quality of health care by increasing both access to it and the competition between providers. However, it may also give patients possibilities for doctor shopping (DS) behaviour, i.e., visiting different providers to receive illicit drug prescriptions. Abuse of prescribed addictive drugs is a growing problem worldwide and is associated ...

    • Extending the Rotterdam Demand Model to Analyze Market Participation 

      Xie, Jinghua; Myrland, Øystein (Journal article; Tidsskriftartikkel; Peer reviewed, 2018-03-01)
      The dependent variable in the Rotterdam model is shown to consist of two additive components: the proportionate change in the average product weight consumed by existing buyers and the proportionate change in the share of total consumers who actually purchase the product. Applying the extended model to household data on salmon consumption in France, results suggest prices have a larger effect on ...

    • Firm Size, Commodity Price, and Interdependence between Firm-Level Stock Prices: The Case of Norwegian Salmon Industry 

      Zhang, Dengjun; Myrland, Øystein; Xie, Jinghua (Journal article; Tidsskriftartikkel; Peer reviewed, 2016-09-08)
      This study aims to investigate the interdependence between stock prices of salmon firms listed at Oslo Stock Exchange and to evaluate how this correlation is affected by firm size and salmon commodity price. Technically, we apply the Johansen’s approach (Johansen, 1991) to test cointegration between stock prices and between individual stock prices and commodity price. The time path of the long-run ...

    • How exchange rate affects Chinese processing trade? The case of ground fish 

      Zhang, Dengjun; Xie, Jinghua; Myrland, Øystein (Journal article; Tidsskriftartikkel; Peer reviewed, 2017-09-25)
      As imports destined for primary processing and then exporting occur across industries, in this study we developed a structural model to examine how exchange rate affects the exports of processed ground fish from China. The home demand for processed goods is incorporated into the model in accordance with the fact that the share of processed goods remaining in China tends to increase over time. ...

    • Measuring inventory turnover efficiency using stochastic frontier analysis: building materials and hardware retail chains in Norway. 

      Breivik, Jørgen; Larsen, Nils Magne; Thyholdt, Sverre Braathen; Myrland, Øystein (Journal article; Tidsskriftartikkel; Peer reviewed, 2021-08-26)
      Operational efficiency in the retail business is vital in order to be profitable in a competitive environment. This paper investigates how environmental factors, firm size and time trends are linked to inventory performance. We use location data, demographic data and 16 years of financial accounting data from small and medium-sized home improvement retailers to explain inventory performance at a ...

    • A note on measuring the effects of exchange rate changes on Norwegian exports of seafood 

      Myrland, Øystein (Working paper; Arbeidsnotat, 2002-09)
      The purpose of this note is to develop a very simple, yet consistent structural model of the Norwegian seafood trade that highlights how trade flows and prices are affected by changes in exchange rates. By using a class of models called Equilibrium Displacement Models (EDM’s) the model is solved for the reduced-form elasticities to indicate the effects exchange rates changes has on producer ...

    • ShinyRBase: Near real-time energy saving models using reactive programming 

      Myrland, Øystein; Severinsen, Alexander (Journal article; Tidsskriftartikkel; Peer reviewed, 2022-08-16)
      To document energy savings from retrofitting a building, a reliable baseline model is needed. The development and implementation of the baseline model is an important step in the measurement and verification (M&V) process. Usually, an energy analyst enters the stage, collects data, do the estimation and delivers the baseline model. The modeling work of the energy analyst is done on either a proprietary ...

    • Statistical learning to estimate energy savings from retrofitting in the Norwegian food retail market 

      Severinsen, Alexander; Myrland, Øystein (Journal article; Tidsskriftartikkel; Peer reviewed, 2022-06-16)
      Buildings worldwide consume about 40% of all produced energy and are major contributors to GHG emissions. Hence, to reach the 2030 European energy efficiency target it is vital to reduce the energy consumption in buildings. An important barrier that hinders renovation projects is uncertainty regarding the expected savings. The main objective of this paper is to present two different statistical ...
