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…

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…

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…

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…

Success Strategies and Knowledge Transfer in Cross-Border Consulting Operations analyzes the international operations of consulting firms. Apart from developing a theoretical framework which differs f…

Dagens konjunkturuppgång betyder inte att alla problem är övervunna. De kvarvarande problemen i Sveriges ekonomi vittnar om brister i våra politiska institutioner. Bristerna bildar ett tydligt mönster…

Vid en högtidlighet på Kungl. Vetenskapsakademien den 20 januari 2000 utdelades till professor Jörgen W. Weibull det Söderbergska priset 1999 i ekonomi på 500 000 kr. Prissumman har ställts till förfo…

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…

This paper discusses how ICT and emerging electronic commerce in consumer products influence the relative efficiency in production of households and firms, resulting in changes in the division of task…

Bergin and Lipman (1996) show that the refinement effect from the random mutations in the adaptive population dynamics in Kandori, Mailath and Rob (1993) and Young (1993) is due to restrictions on how…

This paper presents a model to explain why both industry leaders and follower firms often invest in R&D and explores the welfare implications of these R&D investment choices. Regardless of ini…

Sunk Costs, Firm Size, and Internationalization. — One strand of the industrial organization literature argues that outlays on sunk costs are endogenous in market expansion, implying an adaptive adjus…

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

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…

The purpose of this paper 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 which…

Investigating the robustness of the skill-biased technical change hypothesis, this analysis incorporates two novel features. First, effective labor is modeled as the product of a quantity measure - nu…

The expected consumer’s surplus (ECS) is often used as a monetary measure of consumer welfare. Examples include the theory of regulation, competition policy, and price stabilization. This paper shows…

This paper studies the interaction between the incentives for predation and mergers. I show that the incentive for predation in an oligopoly is limited by the subsequent competition for the prey. This…

A quality-adjusted measure of labour is developed, where labour efficiency depends on firm training. This specification is integrated into a flexible neoclassical cost function, representing the firm'…

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

In a recent review article, Agell et al. (ALO) [Agell, J., Lindh, T., Ohlsson, H., 1997. Growth and the public sector: a critical review essay. European Journal of Political Economy 13, 33–52.] claim…

In the models of Young (1993, Econometrica 61, 57–84; 1993, J. Econ. Theory 59, 145–168), boundedly rational individuals are recurrently matched to play a game, and they play myopic best replies to th…

This thesis consists of two parts, dealing with equilibrium selection in noncooperative games and strategic interaction in international markets, respectively. The main issue raised in each part is di…

FDI has received surprisingly little attention in theoretical and empirical work on openness and growth. This paper presents a theoretical growth model where MNCs directly affect the endogenous growth…

This paper analyzes a three-stage optimization problem in which a firm chooses (i) its technology, by deciding on a level of R&D, (ii) whether this technology is to be used in a domestic or in a f…

We demonstrate a "preemptive merger mechanism" which may explain the empirical puzzle why mergers reduce profits, and raise share prices. A merger may confer strong negative externalities on the firms…

We incorporate transaction taxes in a housing market search model with endogeneous house prices and show that these taxes unambiguously create lock-in effects that reduce welfare. The lock-in effects…

In conjunction with its tercentenary celebrations in 1968, Sveriges Riksbank (Bank of Sweden) instituted a new award, "The Central Bank of Sweden Prize in Economic Sciences in Memory of Alfred Nobel"…

This paper analyzes the interplay between social norms and economic incentives in the context of work decisions in the modem welfare state. We assume that to live off one's own work is a social norm,…

The search for growth-promoting policies is found to demand knowledge of how growth depends upon actions of entrepreneurs and how these actions depend upon the prevailing institutions. While instituti…

This paper considers a small open economy whit an input-output industrial structure that creates vertical linkages multiple equilibria. An imperfect labor market is introduced by assuming unionized la…

What forces determine national differences in the size and industry distribution of employment? We stress the role of the economic policy environment as determined by business taxes, employment securi…

The purpose of the present paper is twofold. First, we formulate a general method of identifying clusters of economic activity in a country or region. The methodology is based on generally available i…

In this paper it is argued that the size distribution of firms may largely be determined by institutional factors. This hypothesis is tested in an exploratory fashion by studying the evolution of the…

MUST (Macroeconomic Uncertainty Strategy) analysis can help identify the demand side of competitive intelligence. It is a key tool by which relevant economic variables can be identified for companies.…

Här diskuteras hur ”samverkan”, ”samarbete” och ”samgående” – tre betydelser av den europeiska integrationen – förhåller sig till varandra på olika sakområden. De ekonomiska artiklarna handlar om hur…

Regleringar och bristande konkurrens i den svenska ekonomin medför betydande kostnader för den enskilde konsumenten. De går hand i hand med höga priser och låg kvalitet på varor och tjänster. På längr…

Utredningar som ligger till grund för pensionsreformer bygger vanligtvis på antaganden om den framtida demografiska och ekonomiska utvecklingen. Dessa är givetvis osäkra och därför öppna för kritik. I…

Mellan 1985 och 1995 minskade antalet sysselsatta industriarbetare med högst grundskoleutbildning från 435.000 till 240.000. Denna studie analyserar en viktig del av denna utveckling, nämligen nedgång…
