Perfect bidder collusion through bribe and request

Games and Economic Behavior, 129, s. 1- 14. Doi: 10.1016/j.geb.2021.05.001

We study collusion in a second-price auction with two bidders in a dynamic environment. One bidder can make a take-it-or-leave-it collusion proposal, which consists of both an offer and a request of bribes, to the opponent. We show that there always exists a robust equilibrium in which the collusion success probability is one. In the equilibrium, for each type of initiator the expected payoff is generally higher than the counterpart in any robust equilibria of the single-option model (Esö and Schummer (2004)) and any other separating equilibria in our model.

Klimatilpasning av vårt bygde miljø og utfordringer ved dagens kost-nytteanalyser

Praktisk økonomi & finans, 37(01), s. 63- 82. Doi: 10.18261/issn.1504-2871-2021-01-07 - Full text in research archive

I løpet av dette århundret vil klimaet endre seg så betydelig i Norge at vi risikerer at vårt eksisterende bygde miljø ikke vil tåle endringene. Bygg og infrastruktur har et planlagt livsløp som strekker seg langt frem i tid, til et klima som er våtere, villere og varmere enn det vi har i dag. For å sikre at våre hjem, skoler, sykehus, arbeidsplasser, veier og annen infrastruktur er robuste på lengre sikt, må vi allerede i dag planlegge for det fremtidige klimaet. All samfunnsplanlegging og investering skal være velbegrunnet og gjennomtenkt. Samfunnsøkonomiske analyser er ofte et krav og en viktig del av beslutningsgrunnlaget til våre forvaltningsorgan. Men, dagens kost-nytteanalyser fanger verken opp kostnadene av klimaendringene godt nok eller nyttene ved ulike klimatilpasningstiltak. Kost-nytteanalyser generelt er heller ikke velegnet til å sikre helhetlig klimatilpasning og samordning på tvers av sektorer. Til dette trenger vi nye metoder og verktøy.

Contract renewal and incentives in public procurement

International Journal of Industrial Organization, 24(2), s. 269- 285.

This paper explores how the government's choice of renewal policy in public procurement programs can be used as a mechanism to provide firms with incentives to supply quality. A public service is produced by several firms. The firms participate in a tournament where they are ranked according to the quality of their services, and rewarded in terms of contract renewals. We analyse the firms' incentives to produce high-quality services, and find that they are maximised if 50% of the contracts are renewed. The optimal renewal policy trades off incentive provision (which requires that a relatively large fraction of the firms are replaced each period) against the entry costs of new firms.
