• Collateral and Repeated Lending 

      Karapetyan, Artashes; Stacescu, Bogdan (Working Papers;18/2012, Working paper, 2012)
      Lending is often associated with significant asymmetric information issues between suppliers of funds and their potential borrowers. Banks can screen their borrowers, or can require them to post collateral in order to ...
    • Credit, House Prices, and Risk Taking by Banks in Norway 

      Karapetyan, Artashes (Staff Memo;13/2011, Working paper, 2011)
      Motivated by alternative explanations of the financial crisis (e.g., Acharya and Richardson, 2010; Taylor, 2007), I study, first, repercussions between house price growth and household credit growth in Norway, and second, ...
    • Does Information Sharing Reduce the Role of Collateral as a Screening Device? 

      Karapetyan, Artashes; Stacescu, Bogdan (Working Papers;19/2012, Working paper, 2012)
      Information sharing and collateral reduce adverse selection costs, but are costly for lenders. When a bank learns more about the types of its rival's borrowers through information sharing (e.g., credit bureaus), it might ...
    • Information Sharing and Information Acquisition in Credit Markets 

      Karapetyan, Artashes; Stacescu, Bogdan (Working Papers;24/2010, Working paper, 2010)

    • Information Sharing and Information Acquisition: Ownership and Coverage 

      Karapetyan, Artashes; Stacescu, Bogdan (Working Papers;23/2011, Working paper, 2011)
      We examine the conditions required for the existence of private credit bureaus, their ownership and coverage. Our model implies that bank consortia will most likely be preferred by banks, but that they will lead to restricted ...
    • Mental Accounting in the Housing Market 

      Almenberg, Johan; Karapetyan, Artashes (Working Papers;20/2010, Working paper, 2010)
      We report evidence that salience may have economically significant effects on homeowners' borrowing behavior, through a bias in favour of less salient but more costly loans. We outline a simple model in which some consumers ...
    • Salience of Debt and Homebuyers’ Credit Decisions 

      Agarwal, Sumit; Karapetyan, Artashes (Working Papers;21/2015, Working paper, 2015)
      We show how a regulatory disclosure of hidden debt can eliminate a large mispricing in housing. In a setting where homebuyers must combine several sources of debt, they are biased towards hidden loans, especially if they ...
    • The Hidden Costs of Hidden Debt 

      Almenberg, Johan; Karapetyan, Artashes (Working Papers;22/2011, Working paper, 2011)
      We report evidence that salience may have economically significant effects on homeowners’ borrowing behavior, through a bias in favour of less salient but more costly loans. Survey evidence corroborates the existence of ...
    • The Risk-Taking Channel of Monetary Policy in Norway 

      Karapetyan, Artashes (Working Papers;5/2016, Working paper, 2016)
      We identify the effects of monetary policy on credit risk-taking using a unique dataset covering the population of corporate borrowers in Norway. We find that a lower benchmark interest rate (interbank rates or overnight ...
