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

This thesis consists of four essays. Its main theme is the location of production in multinational firms. Subsidizing away exports? - A note on strategic trade policy, investigates how strategic trade…

This paper proposes an approach for prediction the pattern of mergers when different mergers are feasible. It generalizes the traditional IO approach, employing ideas on coalition-formation from coope…

By perturbing symmetric coordination games à la Bryant [Bryant, J., 1983. Quarterly Journal of Economics 98, 525–528] we derive unique solutions, the noise-proof equilibria. Our results agree with the…

It is extraordinarily difficult to determine the extent to which the gender wage gap reflects discriminatory behaviors by employers or differences in productive capacities between men and women. We no…

The analysis provides a new explanation for two widespread problems concerning European unemployment policy: the disappointingly small effect of many past reform measures on employment, and the politi…

Sweden experienced exceptionally fast economic growth during the century-long period 1870-1970. This illustrates that a decentralized market economy, highly open to international transactions, may be…

This paper considers the possibility of letting a pay-go pension system mimic a fully funded pension system. Generically, it turns out to be impossible to make a less than fully funded pension system…

This thesis contains two studies. The first study investigates the income distribution among Namibian households. The second study examines the differences in earnings between males and females in the…

Three empirical models for the choice of entry mode in foreign direct investment are compared. In contrast to the models used in earlier studies where the entry decision is taken to be predetermined,…

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…

Theoretical studies have shown that capital gains taxes in the housing market may create lock-in effects, but, so far, no empirical evidence has been presented regarding the size of these effects. For…

This paper takes a step towards formalizing the theoretical interconnections among four post-Industrial Revolution phenomena - the industrialization and growth take-off of rich "northern" nations, mas…

Lam and Schoeni (1993) consider an equation where earnings are explained by schooling and ability. They assume that ability data are lacking and that schooling is measured with error. The estimate obt…

In an analysis of the risk-sharing properties of different types of pension systems, we show that only a fixed-fee pay-as-you-go (PAYG) pension systems can provide intergenerational risk sharing for l…

Based on the notion of affiliation a model is developed which suggests that laws which restrict the firm's flexibility to adjust its employment force resume in higher requirements on potential employe…

The focus of this book is to illustrate successful strategies employed by Nordic firms to internationalize their capital expenditure. Some of the cases capture solutions for companies residing in high…

Global changes and new technologies are in the process of changing the foundations on which society is based. How does the process of globalisation affect business enterprise and economic policy? Hum…

The Geography of Multinational Firms addresses the implications of multinational production, and the forces that determine location. The analytical framework builds on recent developments in the theor…

This paper studies relative productivity and R&D expenditures as detenninants of foreign acquisitions of Swedish manufacturing firms, as well as, the productivity and R&D performance of these…

In a recent review article Jonas Agell, Thomas Lindh and Henry Ohlsson (1997) claim that theoretical and empirical evidence does not allow any conclusion on whether there is a relationship between the…

We compare the relation between foreign affiliate production and parent employment in U.S. manufacturing multinationals with that in Swedish firms. U.S. multinationals appear to have allocated some of…

We compare the relation between foreign affiliate production and parent employment in US manufacturing multinationals with that in Swedish firms. US multinationals appear to have allocated some of the…

We use a specific-factor model to examine the conditions under which policy-makers are able to increase aggregate production of high-tech goods by production or R&D-subsidies in the short and long…

Evolutionary game theory studies the robustness of strategy profiles and sets of strategy profiles with respect to evolutionary forces in games played repeatedly in large populations of boundedly rati…

The paper demonstrates how trade between developing countries can cause the divergence of long-run growth among these countries. The model describes two symmetric countries trading with each other and…

Evolutionary theorizing has a long tradition in economics. Only recently has this approach been brought into the framework of non-cooperative game theory. Evolutionary game theory studies the robustne…

Given a compulsory pension system, we calculate the optimal ratio of marginal contributions to benefits. This ratio is independent of the labor supply elasticity, it increases in the rate of return in…

R&D externalities can imply ranges of aggregate increasing returns to scale in R&D. As a consequence several equilibria can exist involving different numbers of firms and different R&D inv…

This paper deals with the effects of European integration in the EC and EFTA on economic growth. Base regressions suggest that EC and EFTA memberships do in fact have a positive and significant effect…

Demand for less skilled workers decreased dramatically in the US and in other developed countries over the past two decades. We argue that pervasive skill biased technological change rather than incre…

We analyse symmetric coordination games à la Bryant (1983) where a number of players simultaneously choose efforts from a compact interval and the lowest effort determines the output of a publi…

This study investigates changes in the number and the size distribution of firms in Sweden in the period 1968-1993. The number and the size distribution of Swedish firms are compared to the number and…

What factors determine national differences in the size and industry distribution of employment? This study stresses the role of business taxation, employment security laws, credit market policies, wa…

This paper addresses various attempts by so-called new Keynesians, writing mainly in the 1980s and 1990s, to strengthen the analytical basis, in particular the microeconomic foundations, of these asse…

Attention is called to a little explored scarce resource, named 'economic competence', which combines features of human capital and bounded rationality, and can be defined as the non-transferable ('ta…

This paper develops a new analytical approach to the old question whether market conditions may influence the internal efficiency of firms. The basic textbook model of the firm is slightly extended to…

This note elaborates an extension of the paper "Social Norms, the Welfare State, and Voting" by Lindbeck, Nyberg, and Weibull [1]. That paper studies the effects of a social norm against living off ot…

Market exchange is subject to an endogenously-determined level of predation which impedes specialization and gains from trade. Utility-maximizing agents opt between careers in specialized production a…

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

This thesis consists of one essay in industrial organization and two essays in noncooperative game theory. The  first essay (Chapter I) concerns credibility in multimarket competition. The analysis fo…

Post World War II European welfare states experienced several decades of relatively low unemployment, followed by a plague of persistently high unemployment since the 1980's. We impute the higher unem…

This thesis consists of one essay in industrial organization and two essays in non-cooperative game theory.

This paper asks whether net trade in the Middle East and North Africa (MENA) can be explained by differences in comparative costs and in the exploitation of scale economies. Based on a sample of six c…

This paper analyzes the utilization of R&D results in the home and foreign plants of Swedish multinational enterprises (MNEs). The findings indicate that firms' R&D undertaken in the home coun…

The increased use of equity issues on both domestic and foreign capital markets from the early 1980s raises the research question addressed in this article: What are the significant reasons for raisin…

This study investigates changes in the number and the size distribution of firms in Sweden in the period 1968-1993. The number and the size distribution of Swedish firms are compared to the number and…

The strategic importance of risk-management is a concern at the forefront of most organisations. Increasingly, uncertainty about macroeconomic environment of the firm is a major concern. It is essenti…

Institutions and policies in the economic and social fields have been rather experimental in Sweden. The experiences of some of these experiments are also relevant, positively or negatively, for other…

What is the relationship between technological innovation and economic growth? In Technological Systems and Industrial Dynamics, this question is answered through an analysis of four ¿technological sy…

This paper deals, in a general way, with the achievements and problems of welfare state arrangements inwestern Europe. These arrangements naturally differ among countries. In particular, the extent to…

A central dilemma for overburdened welfare states is that many proposed reform strategies either lead to higher marginal effects of taxes and subsidies (called the marginal tax rate from here onwards)…

This study is a background study for Sida's financial sector support strategy. The focus is on southern and eastern Africa. It belongs to a series of background studies commissioned by Sida's task for…

This paper analyses the effect of allowing for a more general production structure in the core-periphery (CP) modeI. Two special cases of fully horizontally and fully vertically integrated fmns are tr…

The paper examines the implications of an important aspect of the ongoing reorganization of work - the move from occupational specialization toward multi-tasking - for centralized wage bargaining. The…

This paper develops a new analytical approach to the old question whether market conditions may influence the internal efficiency of firms. The basic textbook model of the firm is slightly extended to…

The main issue addressed in this paper concerns the relationship between firms' endowments in intangible proprietary assets and their export performance. The impact of investments in foreign productio…

A class of evolutionary selection dynamics is defined, and the defining property, convex monotonicity, is shown to be sufficient and essentially necessary for the elimination of strictly dominated pur…

This paper presents a dynamic general equilibrium model of trade between two advanced countries in which both innovation and skilled acquisition rates are endogenously determined. The model offers a N…

For the U.S. and for Norway it has been established that men and women working in the same occupation for the same employer receive more or less the same pay. So-called within-job wage discrimination…
