Politics in Wage setting: Does government colour matter?
This paper studies the relationship between wage formation and the political colour of the government in an economy with centralized wage bargaining. Ideological, organizational and personal ties between the central trade union and the social democratic political party suggest that the trade union may behave significantly different in wage negotiations under a social democratic than under a conservative government. Using time series data for Norway, we estimate that changing from a conservative to a social democratic central government significantly reduces manufacturing wages and makes wages more responsive to unemployment. This result is consistent with a wage bargaining model augmented by political preferences of the union leaders and suggests that the effect of bargaining coordination depends on the political colour of the government. The estimated effects are both robust with respect to model specification and stable over time.Wages; political regime;time series analysis

Effects of strong and weak non-pharmaceutical interventions on stock market returns: A comparative analysis of Norway and Sweden during the initial phase of the COVID-19 pandemic
In this paper, we examine the behaviour of stock market returns in Norway and Sweden during the early days of the COVID-19 pandemic. We test how the different government interventions chosen in Norway and Sweden, including restrictions such as school closures and travel prohibitions along with economic support, affected equity markets in both countries. Our dataset comprises a panel of data for Norway and Sweden over 221 trading days during the period 1 January to 5 November 2020. The result show that while non-pharmaceutical interventions had few or no effects on Norwegian stock market returns, they positively affected the stock market in Sweden, although the strength of this effect weakened with the increasing number of confirmed COVID-19 cases.publishedVersio
Modeling markups and its determinants: The case of Norwegian industries and regions
In this paper we use an innovative and nonstandard approach to model and estimate markups and market power. The approach uses a regression framework with determinants as well as a random component. We use this innovative tool to investigate the level of market power in Norwegian industries and regions. Norway is an interesting case study because in Norway prices on most consumer goods and services are higher than in similar countries. Given that many studies show substantial and an increasing trend in markup, it is naturally interesting to investigate the market power in different industries and different regions in Norway. We use an unbalanced panel collected by The Norwegian Tax Administration for the period 2000-2018 to address this issue. We find low and non-increasing market power in Norway, which is different from other countries. Further, we find that market powers decrease with firm-size, increase with geographical industrial concentration and decrease with rural location.publishedVersio
Price differentiation in the alpine skiing industry-The challenges of demand shifting and capacity constraints under pandemics
The implementation of variable pricing at ski resorts can shift demand from peak periods to off-peak periods if at least some skiers have the flexibility and willingness to do so. This is often referred to as diversion, or demand shifting, and can directly affect the profit-maximizing prices ski resorts should set for their tickets. In this paper, we first model how diversion is related to various levels of the intra-weekly price differences at a ski resort. Then we use this model to recalculate the optimal variable prices a ski resort should set when accounting for the demand shifting and capacity constraints. The results show that the optimal prices the ski resort should set are influenced by both diversion and capacity constraints. The latter aspect is particularly relevant in the ongoing global pandemic. Ski resort managers can make direct use of our modelling framework and results when implementing new pricing strategies.publishedVersio
Willingness to pay for âgreen skiingâ
In this note we provide preliminary empirical evidence on Norwegian alpine skiersâ willingness-to-pay for season pass attributes that make alpine skiing more sustainable. We focus on two key attributes; (1) compensating for the CO2 emissions associated with the activity by purchasing CO2 quotas and (2) compulsory use of public transportation to/from the ski resort. The results show that there is a substantial interest in season passes that includes CO2 compensation. However, combining season passes with compulsory use of public transportation (ski bus) does not seem to be attractive to Norwegian alpine skiers/snowboarders. The optimal prices of the two alternatives are approximately 11.5% higher (CO2 version) and 25% lower (ski bus version) when compared to are gular season pass.publishedVersio
Economies of scope and scale in the Norwegian electricity industry
Š 2019 The Authors. Published by Elsevier B.V. This is an open access article under the CC BY-NC-ND licenseAn important issue for multi-product firms to consider is economies of scope, i.e., whether there is any benefit from producing two or more products, or whether specializing in producing only one product would be less costly. We examined the economies of scope for Norwegian electricity companies because policy makers have decided to force companies that both generates and distributes electricity to split their operations into two companies, one engaged in generation only and the other in distribution only. We set out to test the validity of the policy makers decision on unbundling generation and distribution. Using data from Norwegian electricity companies for the period 2004â2014, we found evidence of economies of scope, meaning that policy makersâ insistence on separating generation and distribution companies will have increased costs. We also found evidence of economies of scale, meaning that there are cost savings in expanding outputs. Our findings provide important information to consider in future policy decisions in the Norwegian electricity industry, probably with implications for other countriespublishedVersio
Essays on efficiency and economies of scope and scale in electricity networks
The electricity market in Norway has undergone substantial changes in recent decades, which
prompts the need for research on how the industry should be organized. In an indivisible
electricity industry that, on the one side, consists of market-oriented competitive entities in
production and power trading, and, on the other side, natural monopolies within transmission
and distribution, it is of interest to perform cost analysis within the productivity and efficiency
framework. The electricity industry is complex, owing to the fact that production and
consumption must happen simultaneously. After the Energy Act of Norway came into force on
January 1, 1991, only transmission and distribution remained regulated. The regulation of
transmission and distribution serves to avoid the typical disadvantages arising from natural
monopolies. Many countries have gone through the same or similar changes in their respective
industries. In a developing and increasingly global industry regarding power trading, more
regulation is probably needed, not less. The possible future changes in the power gridâowing
to private firms and the ability of households to take advantage of the technological
developments in solar and wind generationâwill probably also affect the regulating task in the
future. The main objective of this thesis is to improve the understanding of efficiency measures
and methods, and to increase the knowledge of the market structure in the Norwegian electricity
distribution industry.
In Essay 1 âEconomies of scale in Norwegian electricity distribution: A quantile regression
approachâ, we investigate scale economies to see if the structure of the industry affects the
costs. If a restructure of the industry would reduce costs for the firms, and, hence, in the
industry, it would mean increased productivity and efficiency. In Essay 2, âEconomies of Scope
and Scale in the Norwegian Electricity Industryâ, we study scale and scope economies.
Economies of scope measures the synergies of producing more than one output. Some
electricity companies in Norway both generate and distribute electricity. If there exist some
positive synergies from producing more than one output, it means that the cost would be higher
if two separate firms produced the same amounts of output of each product as the one firm
producing both products. In Essay 3, âLost economies of scope and potential merger gains in
the Norwegian electricity industryâ, I investigate what are the potential gains from merging the
distribution companies in Norway. Both Essay 1 and Essay 2 state that there are economies of
scale in the industry, meaning that the industry would benefit from increasing the size of the
companies in terms of increased output. Because the output is given, this means that companies
must merge. In Essay 2, we report that there exist economies of scope. Due to the change in the
Energy Act of Norway in 2016, we find that the separation of the integrated firms producing
both generation and distribution services, would increase costs to the industry and, hence, incur
losses by not utilizing economies of scope. If disentangling generation and distribution of
electricity would lead to more mergers of the distribution companies, it is of interest to seek the
potential gains in terms of cost reductions to the industry from such mergers. In Essay 4
âDisentangling Costs of Persistent and Transient Technical Inefficiency and Input
Misallocation: The Case of Norwegian Electricity Distribution Firmsâ, we focus on the fact that
many efficiency studies neglect allocative efficiency, and only concentrate on technical
efficiency. In addition, we also disentangle costs of persistent and transient inefficiency, and
include determinants for both persistent and transient inefficiency

Understanding private equity performance : a review of dynamics driving fund performance
In recent years, more papers on private equity performance have emerged, casting light over a market that earlier was characterised by privacy and secrecy. Early studies mostly use VentureXpert as a data provider, however, data from this provider has been under a lot of criticism lately, and new data providers have emerged. In this thesis, we study the performance of buyout and venture funds from 1990 to 2008 using a dataset from Preqin. Previous studies have mostly focused on IRR or a modification of this metric. We have compared these findings with our results and use a widely reported investment multiple to see if there are discrepancies that can explain the differences in results. Based on findings from other papers, the dataset is of high quality and is less prone to bias compared to datasets previously used in private equity research.
In our study of fund types, we see a general tendency of buyout outperforming venture. We have also looked more closely at sequence numbers and see that there is a negative correlation between performance and sequence numbers. This suggests that experience is not necessarily a contributing factor for good performance. We find indications that past performance may be well suited for risk reduction, but is not necessarily indicative for future performance.
As Preqin has been little used in private equity research, our results contribute to this field by showing that Preqin, as a data provider, is well suited for academic research. We also test the validity of past research and show that, although the concepts are still valid, an update based on newer data points is warranted.nhhma
