The FOOD team is presently working on several topics.

  • Online food sales

    Online food sales

    FOOD aims to increase the understanding on how the introduction of internet stores offering food affects sales in traditional brick-and-mortar stores. Another question analyzed is whether the composition of products bought through the different channels differs. A master thesis is already written by Lundanes and Saltermark (2017) on this topic.

  • Individual pricing

    Individual pricing

    Digitalization of grocery stores allows for dynamic and individual price changes. We try to better understand how this affects sales and prices. For instance, how will various pricing strategies affect the sales of perishable products to minimize wastage? Will individualized prices benefit consumers or sellers? One master thesis (Chadoyan and Faramarzi, 2017) and one research paper (MAGMA, 2017) addressing these questions have so far been written.

  • Border trade

    Border trade

    Norwegians living along the border to Sweden benefit from lower prices on the Swedish side of the border and undertake a significant share of their grocery shopping in Sweden. We will try to quantify better what are the most important factors affecting this trade and also estimate the size of these factors, combining Norwegian and Swedish data.

  • Price sensitivity

    Price sensitivity

    By changing store prices in various ways we are tracing price sensitivity for individual consumers in order to understand how they react to different treatments of price changes, for instance how consumers react to ‘visible’ price changes versus ‘invisible’ price changes.

  • Productivity

    Productivity

    We work to establish better measures of productivity in the grocery sector. Partly by using data from SSB, but also using data from the NG chains. One master thesis (Kay and Sørlie, 2017) is written on this topic so far. Another issue that we will focus on is to better understand differences in productivity across individual stores. This fall a master thesis is focusing on this latter question.

  • Local competition

    Local competition

    How does closeness of rival stores affect prices locally? By looking at store and regional demography, and prices in some local areas, we are able to track some of these price effects. So far this has been the focus of one of our master theses (Olsen and Olsen, 2017).

  • Product range

    Product range

    There has been a large discussion on the potential scarcity of products in Norwegian stores as compared to other national markets. So far we have focused on how peoples’ choices react to changes in product range. This is reported in a recent master thesis (Nyerrød and Tronstad, 2017). We will look further into this topic by following individual buyers’ consumption patterns.

  • Concentration and demography

    Concentration and demography

    Norway stands out as compared to most other countries with regards to the national distribution costs and number of grocery stores. We have gathered information for Denmark, Sweden and Norway on demography, grocery concentration and number of shops over time to analyze to which extent differences in demography can explain differences across these three countries. So far the results are presented in a master thesis by Drager and Vågene, 2017.

  • Loyalty programs

    Loyalty programs

    How does loyalty programs affect consumers and their choices? By conducting surveys we try to better understand the working of loyalty programs. Already some information has been gathered through Chadoyan and Faramarzi’s (2017) recent master thesis. More information will be analyzed in two present master theses that will be complete during the fall of 2017.
