Market definition with shock analysis
(Discussion paper, Working paper, 2007-11)The SSNIP test for market definition requires information about demand substitution and profitability. If detailed information about demand is not available, observed effects of a shock in the industry may be an alternative ... -
Market Power in Retail Gasoline Markets
(DP SAM;21/2019, Working paper, 2019-07)We estimate a structural model to uncover the degree of competition in retail gasoline markets using daily station-level data on quantity and price from the Swedish market. The structural model enables us to consider key ... -
Market shares in two-sided media industries
(Discussion paper, Working paper, 2009-03)This paper generalizes the frequently used Hotelling model for two-sided markets in order to determine the equilibrium market shares. We show that independent of whether consumers are uniformly or non-uniformly distributed, ... -
Markets for public and private health care : redistribution arguments for a mixed system
(Discussion paper, Working paper, 2001-04)Should health care provision be public, private, or both? We look at this question in a setting where people differ in their earnings capacity and express an inelastic demand for health care. We assume that illness reduces ... -
Markup cyclicality and input factor adjustments
(Discussion paper, Working paper, 2008-04)This paper investigates the existence of markups and their cyclical behaviour at industry sector level. Markups are given as a price-cost relation that is estimated from a dynamic, structural model of the firm. The firms ... -
Material resources and well-being – Evidence from an Ethiopian housing lottery
(DP SAM;11/2021, Working paper, 2021-04-26)Do better material conditions improve well-being and mental health? Or does any positive relationship merely reflect that psychological well-being promotes economic success? We supply new responses to these questions by ... -
Measuring heterogeneity in the returns to education in Norway using educational reforms
(Discussion paper, Working paper, 2003-07)The decision to take more education is complex, and is influenced by individual ability, financial constraints, family background, preferences, etc. Such factors, normally unobserved by the researcher, introduce endogeneity ... -
Measuring Market Power in Gasoline Retailing: A Market- or Station Phenomenon?
(DP SAM;6/2018, Working paper, 2018-04)Applying detailed consecutive daily micro data at the gasoline station level from Sweden we estimate a structural model to uncover the degree of competition in the gasoline retail market. We find that retailers do exercise ... -
Measuring the consumption value of higher education
(Discussion paper, Working paper, 2004-02)The consumption value of education is an important, but rather ignored factor behind the individual’s educational choice. This paper suggests a method for measuring the consumption value of education in a compensating ... -
Media competition on the Internet
(Discussion paper, Working paper, 2004-08)This paper presents a model of competition between two advertisingfinanced media firms, and we apply the model to analyze competition between portals on the Internet. First, we show that equilibrium prices of advertising ... -
Media market concentration, advertising levels, and ad prices
(Discussion Papers;24/2011, Working paper, 2011-12)Standard media economics models imply that increased platform com- petition decreases ad levels and that mergers reduce per-viewer ad prices. The empirical evidence, however, is mixed. We attribute the theoretical predictions ... -
Merger profitability in unionized oligopoly
(Discussion paper, Working paper, 2000-05)We examine how a merger affects wages of unionized labour and, in turn, the profitability of a merger under both Cournot and Bertrand competition. If unions are plant-specific, we find that a merger is more profitable ... -
Merger simulations with observed diversion ratios
(Discussion paper, Working paper, 2010-10)A common approach to merger simulations used in antitrust cases is to calibrate demand from market shares and a few additional parameters. When the products involved in the merger case are differentiated along several ... -
Mergers and partial ownership
(Discussion paper, Working paper, 2010-01)In this paper we compare the profitability of a merger to the profitability of a partial ownership arrangement and find that partial ownership arrangements can be more profitable for the acquiring and acquired firm because ... -
Modeling individual choices in experiments : reply to Conte and Moffatt
(Discussion paper, Working paper, 2009-07)In a comment to Cappelen, Hole, Sørensen, and Tungodden (2007b), Conte and Moffatt (2009) challenge our use of a random utility model when studying individual choices in a fairness experiment. They propose an alternative ... -
The more the merrier? : the effect of family composition on children’s education
(Discussion paper, Working paper, 2004-08)Among the perceived inputs in the “production” of child quality is family size; there is an extensive theoretical literature that postulates a tradeoff between child quantity and quality within a family. However, there is ... -
Motivating Low-Achievers—Relative Performance Feedback in Primary Schools
(DP SAM;14/2019, Working paper, 2019-11)Relative performance feedback (RPF) has often been shown to improve effort and performance in the workplace and educational settings. Yet, many studies also document substantial negative effects of RPF, in particular for ... -
Multidimensional screening in a monopolistic insurance market
(Discussion Papers;19/2011, Working paper, 2011-11)In this paper, we consider a population of individuals who differ in two dimensions: their risk type (expected loss) and their risk aversion. We solve for the profit maximizing menu of contracts that a monopolistic insurer ... -
Multidimensional screening in a monopolistic insurance market: proofs
(Discussion Papers;21/2011, Working paper, 2011-11)This technical paper contains the proofs of all lemmata, propo- sitions and other statements made in the paper Multidimensional screening in a monopolistic insurance market. -
Multinational firms : easy come, easy go?
