The purpose of this project was to examine the effects of payroll taxes on employment in the service sector. According to economic theory, the effects on employment are ambiguous. On the one hand, payroll tax reductions stimulate demand for labour in the short run. On the other hand, wages may increase in the long run as they are re-negotiated, which tends to reduce employment.
The effects of a natural experiment in taxation – a reduction of payroll taxes for youth (but not for older employees) during 2007–2009 – are investigated for a particular industry, namely retail. The project considers effects on the number of employees, work hours and wages. Effects on wages per hour (instead of wage bill per employee) and hours have not been considered in the previous literature. Effects on hours may be important in service industries which typically employ workers on a part-time basis.
The project was financed by a research grant from The Institute for Evaluation of Labour Market and Education Policy (IFAU).

Effects of School Choice
In this project, we test how the option to choose between different schools has affected students’ results. Do school choice and competition between schools lead to better results for all through better quality in all schools, and through a better match between students and schools? Or are there also losers from school choice? School choice in Sweden was widely increased in 1992 when a reform allowed students and parents to choose between different municipal, as well as independent, schools. Previous research has shown that competition from independent schools has led to better results in all schools. However, the effect of school choice between municipal schools has not been evaluated to the same extent, even thought this part of the reform may also have had substantial effects.

File sharing, the entertainment industry, and the IPRED-law
We investigate the relationship between file sharing and music and movie sales by evaluating the effects of the Swedish implementation of the IPRED law in 2009.
During the last decade global music sales have fallen drastically. The music industry has claimed that file sharing is the main reason for this. In 2009, the IPRED-law was implemented in Sweden where the aim was to control the widespread practice of file sharing of music and movies. We investigate the effects of the IPRED-law on illegal file sharing of music and movies in Sweden and the indirect the effects of file sharing on music and movie sales.

Incentives in organizations and markets: A development of multi principal agent theory with applications for privatization, competition and outsourcing
This project aims at deepening the study of the intersection between markets and hierarchy/bureaucracy.
This project is partly motivated by a number of questions related to the organization of the public sector that have only been analyzed to a small extent, and also by the lack of a unifying conceptual framwork for studying how incentives are determined in markets, in hierarchies/bureaucracies and in the intersection between markets and organizations. The project aims both to develop theory for how incentives are determined within organizations and in markets, and to apply this theory on questions regarding the organization of public sector services, with a particular focus on Swedish health-care.

Public Services from the Voters' Perspective
We study the interaction of voters and politicans regarding public services. How do voters react to changes in prices and supply of public services?
Public consumption makes up 51 percent of public expenditures in Sweden and consists almost exclusively of services. Counties and municipalities have tried different approaches to meet the voters' demand for public services such as health care, education and elderly care. We capture the voters' opinions by using opinion surveys, such as the Swedish Election Studies.
The project was financed by a program grant from the Jan Wallander and Tom Hedelius Foundation.

Public and Private Production of Publicly Financed Services
There is a trend moving towards private production of publicly financed services. This project studies the economic consequences of the choice between public and private production in terms of cost and quality.
International studies indicate that public procurement of transportations and technical activities may result in cost reductions of up to 30 per cent compared with public production. For "softer" activities the cost savings potential is considerably smaller and for health-care it is highly uncertain. According to the judgment of the Swedish Competition Authority, public services of about 250 billion SEK could be opened to competition between private producers. On the other hand, private production comes with a loss of control for the public principal with the risk of reduced service quality.
A starting-point is that all public services are not equally suited to contracting out. Differences between public and private production arise in the interplay of production mode, competition, and difficulties of contracting. The output of the project will include a survey paper on outsourcing of publicly financed services and an empirical study of Swedish municipalities.

Public Service Contracting and Regional Development
Service contracting makes up a significant and increasing share of public expenditure in Swedish municipalities. Previous research has compared cost and quality of publicly financed services that are either produced in house or purchased from private companies. This project studied how this make or buy decision in Swedish municipalities varies with regional business structure and economic development. In particular the political explanations of public sector outsourcing was studied.

Child Care and Long Run Labor Supply
The purpose of the project was to study the effects of subsidized childcare on long run labor supply and access to human capital.
Child care costs and accessibility can impact long run labor supply by affecting the size and quality of tomorrow’s labor force: size, through the birth rate, and quality, through a child’s development and human capital accumulation later in life. Understanding the determinants of fertility is central in today’s Europe, where problems arising from low fertility are of great concern. Moreover, in a knowledge-based society, it is important to uncover the preconditions for human capital accumulation, both for the growth potential of the economy, and to prevent disadvantaged children from falling behind.
Three topics were studied in the project:
1) Exploiting the natural experiment created by the implementation of the Swedish childcare cost reform of 2002, we study the causal effect of child care costs on fertility.
2) Using the same natural experiment as above, we study the impact of child care on child and parent health as measured by patient- and insurance register data.
3) Long run causal effects of childcare on education in adulthood are identified using regional variation in the timing of the Swedish 1970´s childcare expansion.
The project was financed by a research grant from the Bank of Sweden Tercentenary Foundation.

COINVEST – Competitiveness, Innovation and Intangible Investment in Europe
The project was aimed at understanding the contributions of intangible investments to innovation, competitiveness, growth and productivity in Europe. Intangible investments are, with a few exceptions, either not measured, or treated as an intermediate input into production. This means that they are assumed to produce no durable assets for firms or economies. Some knowledge investment is counted as such in the key economic measures such as GDP (e.g. software). However, R&D and other knowledge investment (like investment in human capital via training, investment in reputation capital, investment in organisational capital etc) are all treated as day-to-day expenses, not investment. Thus, under current conventions, investment and GDP in an economy whose businesses spend €1 more on almost all knowledge investment is the same as an economy whose businesses turn up their air-conditioning. The researchers working on the project have collected data on a wide range of intangible investments and incorporated these into economic performance measures in order to improve our understanding of knowledge-driven economies and firms.
COINVEST was a collaborative project involving seven European research organizations (in Belgium, Bulgaria, France, Germany, Portugal, Sweden, and the UK). The project is supported by funding from the European Commission under its Seventh Framework Programme.

Platforms and Policy in the Telecommunications and High-Technology Industry
In two-sided markets, platforms connect and facilitate transactions between separate groups of agents that value each other’s presence. Platforms are common in the telecommunications and high-technology sectors. For example, in telecommunications, Internet service providers connect consumers and companies providing services over the internet. In the high-tech sector, software and hardware companies connect consumers and companies developing applications for the platform. Platforms in these markets must serve both groups of customers and design pricing and business strategies so as to get both sides onboard.
This research project aims to develop the theory of two-sided markets and use this theory to provide guidance for regulation and policy in the telecommunications and high-technology industry. The focus is two-fold.
1. To evaluate Net neutrality regulation on the Internet. An important feature of the Internet is that it can be characterized as a two-sided market. Since the inception of the Internet, information packets are transported on the Internet under “net neutrality,” a regime that does not distinguish in terms of price between bits or packets depending on the services that these bits and packets are used for. But recently, Internet broadband access providers in the Unites States have demanded rights to additional compensation for carrying valuable digital services. Granting them this would be a sharp departure from the net neutrality regime and has started an intensive debate about the underlying structure of the Internet and how communications companies operating the network should be regulated.
2. To develop theory and to evaluate policy relating to open and closed platforms. It is important to recognize that many software and hardware platforms in two-sided markets have a choice. They could allow external companies to interface with their product (and provide open platforms), or they could choose to close the interface (and provide closed platforms).

Competition and Regulation in Electronic Communications
The purpose of this research project is to contribute to the understanding of the determinants of interconnection charges in electronic communications and the effect of competition and regulatory policies on market conduct.
Broadly speaking, the purpose of this research project is to analyze three issues. First, how does the mobile telecom market function, and what is the need for public intervention? Despite the many sources of market failure in telecommunications, the benefits of public intervention are uncertain. In fact, there are estimates that the 26 US states with price controls had prices that where 15 percent higher than the states without price controls, holding other economic factors equal. Second, how should one evaluate the effects of political intervention in the mobile telecom industry? Concerning the new European regulatory framework such an evaluation is already scheduled to be started in about two years time. Third, how should the national regulatory agencies carry out their duties, such as delineating markets, measuring market power and metering out appropriate remedies, under the new regulatory framework?
