This paper provides a unified explanation for why blacks commit more crime, are located in poorer neighborhoods and receive lower wages than whites. If everybody believes that blacks are more criminal…

We develop a model in which delinquents compete with each other in criminal activities but may benefit from being friends with other criminals by learning and acquiring proper know-how on the crime bu…

We analyze an oligopoly model in which differentiated criminal organizations globally compete on criminal activities and engage in local corruption to avoid punishment. When law enforcers are sufficie…

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…

Value Based Management (VBM) has become a common tool for evaluating corporate strategies and projects from the perspective of shareholder value maximization, and can be an important input for corpora…

The new information and communication technology, ICT, induces households to take over tasks from firms and government agencies, using tools and systems provided by these very same organizations. The…

This paper presents a new approach to the theory of the firm by identifying factor complementarities as central to the determination of the firm's boundaries. The factor complementarities may take a v…

The expansion of welfare-state arrangements is seen as the result of dynamic interaction between market behaviour and political behaviour, often with considerable time lags, sometimes generating eithe…

The regional voting pattern of the Swedish EU-membership referendum is analyzed to determine voters' preferences over two fiscal regimes: an autonomous Sweden, or Sweden as part of the EU. A major dif…

This paper aims to explain the spatial variations of crime, both between and within cities. Two types of mechanisms are put forward: Social interactions that stipulate that an individual is more likel…

The paper analyses the interaction between economic incentives and work norms in the context of social insurance. If the work norm is endogenous in the sense that it is weaker when the population shar…

We analyze the development of the Swedish ownership model after World War II. The controlling ownership in Swedish firms is typically concentrated to one or two owners. Often, but not always, the cont…

In Europe, accounting standards prevent larger expenditures on employer-sponsored training from being treated as investments. Using Sweden as example, we discuss two consequences for training. First,…

We classify social security pension systems in three dimensions: actuarial versus non-actuarial, funded versus unfunded, and defined-benefit versus defined-contribution systems. Recent pension reforms…

A "chain of replacement" model is used to examine the effects of automobile taxes and of a scrappage premium on the life length of cars, and on the size of the car fleet. The predictions of the model…

The Knowledge Capital Model (KC-model), described in Markusen (2002), encompasses both market size (horizontal) as well as factor endowment (vertical) explanations to why multinational production occu…

In imperfectly competitive markets firms with high costs produce positive output. The market’s ability to minimize costs is also constrained by the fact that firms’ costs are often private information.…

We investigate experimentally how the share of experienced traders in double-auction asset markets affects trading, in particular the occurrence of bubble-crash pricing patterns. In each session, six…

The achievements of social-welfare arrangements in Western Europe are well known: considerable income security, relatively little poverty and, in some countries, ample supply of social services. But t…

At the end of the last millennium, we experienced a boom in merger and acquisition (M&A) deals in the world. The value of all M&As as a share of world GDP rose from 0.3 per cent in 1980 to 8 p…

Den Europeiska unionen har de närmaste åren att hantera tre stora utmaningar. För det första står östutvidgningen för dörren. Vi kommer att få se en större och samtidigt mer heterogen union. De politi…

This book addresses the controversial call for international labor standards, seeking to productively further this debate by considering the economic implications and history of these standards. A res…

Vad skulle en anslutning till den europeiska gemensamma valutan innebära för Sverige? Frågorna är många om vad som i så fall händer med priser, företag, kapital och den enskildes ekonomi. I Därför eur…

This book was the first in a groundbreaking series of annual volumes utilized in the development of an American Law Institute (ALI) project on World Trade Organization Law. The project undertakes year…

‘These eleven small, open economies teach us a great deal about the behaviour of money and financial markets. This volume sets the standard for investigating them. Any future serious work must take ac…

This thesis consists of three essays, which all concern the dynamics ofpension reform. The first essay analyzes the dynamic properties of therecently reformed Swedish pay-as-you-go pension system. The…

We provide a cultural explanation to the phenomenon of corruption in the framework of an overlapping generations model with intergenerational transmission of values. We show that the economy has two s…

The growth effects of international financial liberalization and integration are investigated using the methodology and data developed by Rajan and Zingales (1998). The main result is that industries…

The paper analyses the interaction between economic incentives and work norms in the context of social insurance. If the work norm is endogenous in the sense that it is weaker when the population shar…

This paper considers the effects of union-bargained minimum wages on transitions into and out of employment in the hotels and catering industry over the period 1979–99. This industry is characterised…

In this paper, I analyze the commercialization of patents in the Swedish medicine & hygiene sector. A unique database makes it possible to use a new method, where I follow the commercialization pr…

We construct a model in which a number of equally powerful ethnic groups compete for power by engaging in civil war. In non-redistributive equilibrium, ethnically homogeneous and ethnically diverse co…

If protectionist trade policies aim to insure domestic industries against swings in world market prices, the development of financial markets could lead to trade liberalization. Likewise, trade libera…

A people's culture, norms and habits are important determinants not just of the quality of social life but of economic progress and growth. In this paper we take the view that while the importance of…

Developing countries, in particular the least developed ones, probably have more to learn from social policies in Europe during the early 20th century than from the elaborate welfare-state arrangement…

We characterize pension systems along three dimensions: 1) actuarial vs. non-actuarial, 2) funded vs. pay-as-you-go, 3) defined-contribution vs. defined-benefit. Increasing the degree of actuarial fai…

An important issue in the debate on voucher systems and school choice is what effects competition from independent schools will have on public schools. Sweden has made a radical reform of its system f…

This study explores how relative skilled-wage premia affect FDI. Contrary to previous studies based on factor endowment differences, we find strong support for vertical FDI, in the sense that more FDI…

Dynamic decision-making without commitment is usually modelled as a game between the current and future selves of the decision maker. It has been observed that if the time-horizon is infinite, then su…

Real exchange and interest rates may still fluctuate inside the EMU and give rise to changes in competitiveness. We find, in contrast to what is generally expected, no convergence in these variables a…

Is discounting of future instantaneous utilities consistent with altruism towards future selves? More precisely, can temporal preferences, expressed as a sum of discounted instantaneous utilities, be…

Value Based Management (VBM) has become a common tool for ex ante and ex post evaluation of corporate strategies and projects from the perspective of shareholder value maximization (SVM). VBM-framewor…

This paper analyses simultaneous regulation of cost and quality when firms have private, correlated information about productivity and the regulator receives a signal about quality. It is shown that m…

We investigate whether temporal preferences expressed as a sum of discounted consumption utilities can be derived from a welfare representation in the form of a sum of discounted total utilities. We f…

Increased integration and growing macroeconomic fluctuations require more attention to be paid to the link between the ”noise” that these fluctuations represent and the company’s own development. For…

We investigate the interaction between cross-border acquisitions and greenfield entry in a multi-firm setting. It is shown that the net profits of the acquirer may decrease when the acquisition gives…

In the traditional trade literature, there is a well-developed area analyzing the effect of growth on trade and its reflection on income growth. This literature developed already in the 1950s and 1960…

This paper analyzes the simultaneous relationship between R&D and foreign sales in Swedish multinational enterprises (MNEs). We argue that this two-way relationship should especially apply to mult…

Experiences of social policies during the first decades of the 20th century in Europe underline the important role of informal systems for income security and personal services at low levels of econom…
