Imports of pulpwood and price discrimination: A test of buying power in the swedish pulpwood market
- 1999

Tidskriftsartikel (refereegranskat)abstract
- The Swedish pulp and paper industry's ability to exert monopsony power is tested both with a conjectural variation model, which parameterizes the firms' expectations about other firms' behavior, and with a model that estimates country-specific effects and effects of currency fluctuations on import prices. We use industry data for the 1970-1993 period and find only weak evidence of market power, in spite of the apparent lack of competition.

Emendment to the term complex in: “Guide for geological nomenclature in Sweden” (Kumpulainen 2016)

Tidskriftsartikel (övrigt vetenskapligt/konstnärligt)abstract
- Since the publication of Kumpulainen (2016), the Committeehave been alerted by the investigation and subsequent changesto the North American Stratigraphic Code concerning thelithodemic unit“complex”(Easton et al.2016; North Ameri-can Commission on Stratigraphic Nomenclature (NACSN)2017). These changes concern the introduction of the nomen-clature unit“Intrusive Complex”. In the original version(NACSN1983), as well as in the Swedish Guide for nomencla-ture (Kumpulainen2016), the unit“complex”is defined ascontaining at least two genetic classes of rocks, i.e., igneous,sedimentary, or metamorphic.

The impact of generic drug competition on brand name market shares - evidence from micro data
- 2001
-
Ingår i: Review of Industrial Organization. - : Kluwer Academic Publishers. - 0889-938X .- 1573-7160. ; 19:4, s. 423-433
-
Tidskriftsartikel (refereegranskat)abstract
- This paper analyses how market shares for brand name drugs are affected by generic competition. The analysis is based on micro data for twelve different original drugs, which are all subject to generic competition. For five of these drugs, we find that the price of the original relative to the average price of the generic substitutes significantly affects the market share of the original drug. In addition, the introduction of a so called "reference price" system appears to have had a significant impact on the market shares of five original drugs.

Auditing and compliance in public procurement – an empirical assessment
- 2023
-
Ingår i: Journal of Public Procurement. - : Emerald Group Publishing Limited. - 1535-0118 .- 2150-6930. ; 23:2, s. 125-144
-
Tidskriftsartikel (refereegranskat)abstract
- Purpose: This study aims to empirically evaluate the effectiveness of government auditing of local authorities’ compliance with the procurement rules.Design/methodology/approach: A diff-in-diff approach is used where the measure of compliance is (changes in) the incidence of private litigation under the Public Procurement Act, in audited vs non-audited municipalities. Further, semi-structured interviews were conducted with chief procurement officials.Findings: No statistically significant effect is found. While strong effects of audits can be ruled out, the statistical results and the interviews do not, however, contradict a modest but long-lasting effect.Originality/value: Few studies have addressed the effect of public procurement auditing on compliance. This study develops an empirical framework and presents empirical results.

Choice and Competition in the Welfare State : Home Care as the Ideal Quasi-market
- 2018
-
Rapport (populärvet., debatt m.m.)abstract
- We study a reform by which a standardized model of choice and competition was introduced in tax-financed home care in a majority of Swedish municipalities. The market for home care is of particular interest since it is close to the ideal quasi-market. For identification, we exploit the different timing of reform implementation across municipalities. We find that the introduction of free choice and free entry in home care increased perceived quality by about one quarter of a standard deviation without affecting costs. Since satisfaction is unrelated to the private market share, the underlying mechanism seems to be new choice opportunities rather than competition or an advantage of private providers.

Comparing merger policies in the European Union and the United States
- 2010
-
Ingår i: Review of Industrial Organization. - : Springer. - 0889-938X .- 1573-7160. ; 36:4, s. 305-331
-
Tidskriftsartikel (refereegranskat)abstract
- We collect a sample of EU and US merger investigations, estimate models of the regulatory decisions, and use the models to compare merger policies. Our approach allows us to decompose observed differences into policy effects and case-mix effects. Focusing on dominance mergers, we find that the EU is tougher than the US on average, in particular for mergers resulting in moderate market shares. However, the US appears to be more aggressive for coordinated interaction and non-dominance unilateral effects cases. Overall, our analysis detects substantial differences in policies, but it does not classify one regime as being more aggressive than the other.

Does Merger Policy Converge After the 2004 European Union Reform?
- 2019
-
Ingår i: Journal of Competition Law and Economics. - : Oxford University Press. - 1744-6414 .- 1744-6422. ; 15:1, s. 664-689
-
Tidskriftsartikel (refereegranskat)abstract
- The European Union (EU) formally changed its merger policy in 2004, moving from a dominance standard to one based on a significant impediment of effective competition, which appears more closely aligned with the U.S. substantial lessening of competition standard. We use data from both before and after this reform to explore whether EU policy has converged toward the U.S. standard. We start by identifying changes in the EU regime and detect a softer EU policy for unilateral effects. We model the outcomes of EU and U.S. investigations with logit models and use their predictions in decompositions and other exercises to show policy convergence for unilateral effects cases.

Interactions Across Firms and Bid Rigging
- 2020

Ingår i: Review of Industrial Organization. - : Springer. - 0889-938X .- 1573-7160. ; 56:1, s. 107-130

Tidskriftsartikel (refereegranskat)abstract
- We evaluate whether an econometric technique that is used in the spatial econometrics and network effects literature can be adopted as a test for collusive bidding in public procurement auctions. The proposed method is applied to the Swedish asphalt cartel that was discovered in 2001. Our dataset covers the period 1995–2009, which makes it possible to test for conditional independence between complementary cartel bids before and after 2001. Our estimates show a significant positive correlation between complementary cartel bids during the cartel period, whereas a non-significant correlation is shown during the later period. The variance of the parameter estimate of interest also differs between the periods, which suggests a structural change in bidding behavior among cartel members between the two periods.
