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 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…

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…

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…

What were the asserted complementarities between the welfare state and full-employment policies, and why do these complementarities look less convincing today?

This paper shows that the liberalisation of foreign direct investment (FDI) tends to make the effect of labour costs on domestic investment and labour demand more negative. Using data from Germany, it…

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…

How do we explain the poor employment performance in Western Europe since about the-1970s? This question is in fact twofold : What initiated the dramatic rise in employment, and waht mechanisms have m…

This paper contributes to research endogenizing multinational firms in general-equilibrium trade models. We attempt to integrate separate contributions on horizontal multinationals which produce the s…

We propose a simple model to analyze the widespread idea that a necessary condition for firms to make foreign direct investments is that they have firm-specific advantages with respect to host country…

By combining unique data on Swedish multinationals with industry data for 18 countries, the influence of host country characteristics on the location of foreign production is analysed. Particular atte…

This paper studies how product differentiation affects collusive pricing in a duopoly when products are horizontally differentiated and firms compete in prices. In contrast to earlier work, the punish…

These notes discuss some of the main results and models from the theory of international trade under imperfect competition. They are necessairy both selective and superficial. Multinationals are consp…

This paper presents recent trends in the foreign activities of Swedish multinationals. The focus is on the distribution of production and R&D between the MNCs' domestic and foreign units, and the…

There is no simple relationship between internationalization of firms' operations and expanding trade. The variation in exports from Swedish affiliates is here shown to be influenced by properties rel…

Several recent articles claim that pre-tax income equality promotes growth. Equality is argued to dampen demand for redistributive economic policies that tax returns to growth-enhancing activities suc…

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

This paper examines the determinants of overseas R&D by Swedish multinationals. Our empirical results indicate that the location of R&D abroad to a large extent is motivated by the need to ada…

This paper analyzes the simultaneous relationship between R&D and foreign sales in Swedish multinational enterprises in the manufacturing sector. We argue that this two-way relationship should esp…

This paper examines whether Swedish multinational enterprises transfer R&D-generated knowledge to their foreign affiliates. The empirical results suggest that such technology transfer takes place…

A quality-adjusted specification of labor is suggested which allows firm training to affect labor efficiency. To assess the cost and productivity effects, this specification is integrated into a flexi…

This paper analyzes the interplay between economic incentives and social norms in a public finance context. We assume that to live off one's own work is a social norm, and that the larger the populati…

This thesis analyzes different aspects of research and development (R&D) and technology transfer by Swedish multinational enterprises (MNEs). Following an introductory chapter are four separate em…

In spite of some cutbacks in entitlements, many welfare states' spending has continuously increased over the past decades, leading to larger tax burdens and often higher marginal tax rates. Proposals…

This paper examines the evolution of a skew distribution of firm sizes from the viewpoint of the 'Bounds' approach to market structure. It confines attention to the role played by non-strategic factor…

The paper shows how prolonged price inertia can arise in a macroeconomic system in which there are temporary price rigidities as well as production lags in the use of intermediate goods. In this conte…

This paper examines equilibrium and stability in symmetric two-player cheap-talk games. In particular, we characterize the set of neutrally stable outcomes in finite cheap-talk 2 x 2 coordination game…

This dissertation examines some issues related to multinational corporations (MNCs). All studies are based on a unique data set of individual Swedish MNCs collected over many years by the Industrial I…
