The competitive effect of international market integration in industries with imperfect competition is of great policy interest. This paper focuses on the link between monopolization and market segmen…

What is the impact of the increasing dominance of conventional firms in e-commerce? We use a simple model to show that retailers who only sell through Internet have lower on-line prices than retailers…

Markets with imperfect competition do not induce a cost-minimizing allocation of production between firms. The market's ability to rationalize production is even more limited if costs are private info…

This paper considers a small open economy with an input–output industrial structure that creates vertical linkages and multiple equilibria. An imperfect labor market is introduced by assuming unionize…

This report studies the importance of efficiency gains from horizontal mergers. A general theme throughout this report is that efficiency gains, and their pass-on to consumers, may vary substantially…

Children who can count on support from altruistic parents may not try hard to succeed in the labor market. Moreover, parental altruism makes withdrawal of such support non-credible. To promote work ef…

In Capitalism, Socialism and Democracy Joseph A. Schumpeter concluded that socialism would eventually displace capitalism in Western democracies. This would come about as a result of the superior perf…

In intermediate goods markets, both buyers and sellers normally have market power, and sales are based on bilaterally negotiated contracts specifying both price and quantity. In our model, pairs of bu…

This article argues that the body of foreign direct investment (FDI) literature in general and the ownership, location, and internalization (OLI) paradigm in particular would be enriched if finance-sp…

Multinational enterprises (MNEs) are important in transmitting technology across national borders. Not only do they allow for transfer of technology within the firm, but it is also believed that they…

The poorest nations of the world suffer from extreme disease burdens, which go largely untreated because weak incomes and the prevailing system of intellectual property rights fail to provide sufficie…

Mergers and acquisitions (M&A) is the dominant form of Foreign Direct Investment (FDI), but has only received scarce attention in the theory literature on trade and investment. This paper highligh…

Most econometric studies of equity market integration suggest that national markets are increasingly becoming part of a global equity market. As regards the extent of this integration, however, the re…

Recent developments in society have generated misalignment between the welfare state and socio-economic conditions and preferences. This paper emphasis developments in the labor market and the structu…

We analyse the effect on agglomeration tendencies of allowing multi‐region firms in a standard trade and location model, the core–periphery (CP) model developed by Kurgman (1991). The introduction of…

Unlike previous analyses, we consider (i) that IT may affect productivity growth both directly and indirectly, through human capital interactions, and (ii) possible externalities in the use of IT. Exa…

The paper discusses the consequences for the functioning of different pension systems of various types of socioeconomic changes, mainly demographic developments, variations in productivity growth and…

A unique database on individual proposals is used to analyse competition among consulting firms (CFs) for international projects. CFs, which sell services based on human capital, focus on developing c…

Standards and technical regulations which govern the admissibility of imported goods into an economy raise costs of exporters entering new markets, and may have a particularly high impact on firms see…

imports is unlimited, the manufacturer chooses deterrence and international prices converge. Second, with endogenously limited arbitrage the manufacturing firm accommodates and the price in the home m…

This thesis consists of a collection of essays on endogenous merger theory. Essay I: The empirical puzzle why mergers reduce profits, and raise share prices is explained in this essay. If being an "in…

Med Nicefördraget löstes en del institutionella frågor, men resultatet anses allmänt vara minimalt i förhållande till vad som hade behövts. För första gången sedan vi blev medlemmar 1995 är Sverige un…

We derive a family of probabilistic choice models including the multinomial logit model, from a microeconomic model in which the decision maker has to make some effort in order to avoid mistakes when…

The purpose of this report is to contribute to the analysis of two questions. Should a merger control system take into account efficiency gains from horizontal mergers, and balance these gains against…

In this paper, a model of product innovation is developed that endogenizes the degree of cooperation. Two opposing forces affect firm profit in an R&D joint venture. Cooperation increases the qual…

Anticompetitive mergers increase competitors' profits, since they reduce competition. Using a model of endogenous mergers, we show that such mergers nevertheless may reduce the competitors' share-pric…

Anticompetitive mergers benefit competitors more than the merging firms. We show that such externalities reduce firms' incentives to merge (a holdup mechanism). Firms delay merger proposals, thereby f…

This paper presents the results of a survey of Swedish multinationals conducted in 1999. The survey was carried out in order to update an existing database on Swedish manufacturing firms with producin…

This paper analyzes empirically the relationship between R&D and growth. The estimated elasticity of per capita R&D expenditures with respect to domestic per capita incomes lies between 1.81 a…

The main result of this study is that a financial constraint may serve as a disciplining device on the internal efficiency of a firm, and the tougher the product market competition, the higher the dis…

A model of occupational choice and human capital investment is developed and tested. The model allows family background to influence occupational choice via access to economic resources, differences i…

This paper analyses the effects of price and market size variables on the investment propensities in the pulp and paper industry. A panel of 15 European countries in the time period 1984 - 1997 is use…

Decentralisation of decision-making in active labour market policy makes it possible to use local information to the fullest, but may also impinge on the fulfilment of national objectives, as suggeste…

This paper determines the equilibrium market structure in a mixed international oligopoly, where the state assets are sold at an auction. The model suggests that low greenfield costs and low trade cos…

This study uses data on Swedish multinationals to estimate cross‐elasticities of labor demand in different locations. With a vertical decomposition of the firm’s activities, whether there is substitut…

I study the evolution of rationality, using an indirect evolutionary approach, in which nature selects a decision-making procedure, and the procedure chooses actions in matching-games. The main result…

This paper presents a unified analytical framework for the analysis of social security reform. It discusses reform along two dimensions: Pay-As-You-Go versus fully funded on the one hand, and actuaria…

This paper examines equilibrium and stability in symmetric two-player cheap-talk games and specifically characterizes the set of neutrally stable outcomes in cheap-talk 2 × 2 coordination games. With…

This paper provides deterministic approximation results for stochastic processes that arise when finite populations recurrently play finite games. The deterministic approximation is defined in continu…

The classical Roy-model of selection on the labor market is extended in order to analyze intergenerational mobility. This is done by linking ability uncertainty to family background. I derive implicat…

The purpose of this article is to examine the effects of European integration on the location of investments by Swedish multinational corporations (MNCs). Evidence is presented about the extent to whi…

Consulting firms (CFs) sell services on a project basis to many clients and must therefore continuously tender for new contracts. One frequently used strategy by CFs is to visit the clients in connect…

This paper determines the equilibrium market structure in an international oligopoly which is opened up by a privatization. Market power is shown to be an important determinant of the equilibrium mark…

The recent 'scientification' of commercial technology has brought the interface between universities and industry into sharp focus. In particular, academic entrepreneurship, i.e., the variety of ways…

Centralized wage-setting institutions compress relative wages. Motivated by this fact, we investigate the effects of centralized wage setting on the industry distribution of employment. We examine Swe…

Most econometric studies of equity market integration suggest that national markets are increasingly becoming part of a global equity market. As regards the extent of this integration, however, the re…

The paper examines the determinants of the division of labor within firms. It provides an explanation of the pervasive observed changes in work organization away from the traditional functional depart…

Experimentalists frequently claim that human subjects in the laboratory violate such game-theoretic solutions as Nash equilibrium and subgame perfect equilibrium. It is here argued that this claim is…

Under de förestående 40 åren kommer den allt större andelen av pensionärer i samhället sannolikt leda till en avsevärd ökning av den offentliga sektorns pensionsutgifter som andel av BNP. Denna ökning…

Most previous studies have found evidence at the aggregate level that female entrepreneurs underperform relative to their male counterparts. This study conducts a comprehensive test of this finding. T…

New information and communication technology (ICT) makes consumers better informed about available products, product quality and prices, which mitigates problems of asymmetric information. The entry o…

Europasamarbetet går in i ett nytt årtusende. När kalenderns årssiffror förra gången alla samtidigt slog om, befann vi oss i början av medeltiden. Ytterligare en gång tidigare, vid den västerländska t…
