This paper is concerned with a comparison of immigrants and Swiss citizens with respect to level of education, labor market outcomes and healthcare utilization. The evidence is based on data for 1999 from the first wave of the Swiss Household Panel. In order to control for confounding influences, linear and non-linear (negative binomial) regressio nmodels are used. The main result is that differences in economic position between immigrants and Swiss nationals tend to be smaller than those found in other countries. The observed differences (higher employment levels of immigrant women, lower earnings of immigrant men, higher healthcare utilization rates of all immigrants) tend to be no larger than those observed between Swiss citizens living in different parts of the country.

"We present a model in which two of the most important features of the long-run growth process are reconciled: the massive changes in the structure of production and employment; and the Kaldor facts of economic growth. We assume that households expand their consumption along a hierarchy of needs and firms introduce continuously new products. In equilibrium industries with an expanding and those with a declining employment share co-exist, and each such industry goes (or has already gone) through a cycle of take-off, maturity, and stagnation. Nonetheless macroeconomic aggregates grow pari passu at a constant rate."

The paper studies the demand for foreign university graduates at the firm level. Using a unique dataset on recruitment policies of firms in four European countries, the determinants of demand for internationally mobile highly skilled employees are established. I investigate the number, origin, skills, and functions of foreign graduates, as well as the experiences of firms recruiting internationally. A number of hypotheses for the international demand are formulated and assessed. Foreign highly-skilled employees are recruited mainly because of their special skills that are not available domestically, be it international competence or technical know-how.

Though the Multilateral Agreement on Investment (MAI) has failed, the original draft is likely to serve as a basis for future negotiations. This article gives a critical assessment of the draft from an industrial economics point of view. First, I summarize the contents of the agreement which is relevant for market structure and competition. Then I develop the industrial economics approach, which serves as a basis for criticism. I conclude that a multilateral agreement on investment should (i) recognize competition concerns, (ii) give a suitable de.nition of investment, and (iii) should help to establish competition authorities in less developed countries.

In 1997, the Swiss government introduced active labor market programs on a large scale to improve the job chances of unemployed workers. This paper evaluates the effect of these programs on the duration of unemployment. Our evaluation methodology allows for selectivity affecting the inflow into programs. We find that in most cases the programs do not reduce the duration of unemployment. The exception is the program of temporary wage subsidies which reduces unemployment, but only for foreign workers. From a cost-benefit point of view, temporary wage subsidies seem to be the only program worthwhile pursuing.

A substantial number of people exhibit social preferences, which means they are not solely motivated by material self-interest but also care positively or negatively for the material payoffs of relevant reference agents. We show empirically that economists fail to understand fundamental economic questions when they disregard social preferences, in particular, that without taking social preferences into account, it is not possible to understand adequately (i) the effects of competition on market outcomes, (ii) laws governing cooperation and collective action, (iii) effects and the determinants of material incentives, (iv) which contracts and property rights arrangements are optimal, and (v) important forces shaping social norms and market failures.

"""Winner-Take-All""-markets, i.e. markets in which the relative and not the absolute performance is decisive, have gained in importance. Such markets have a tendency to provoke inefficiently many entries. We investigate the functioning of such markets with the help of experiments and show that there are even more inefficient entries than predicted by the Nash equilibrium. Moreover, this effect increases with group size. Quantal response equilibrium predicts the increase in group size but fails to predict the excess entry in the smaller group. We show that the excess entry is not caused by coordination failures. Furthermore, individual entry behavior is not significantly linked to risk preferences. We discuss several concepts that might explain the observed excess entry."

Experimental games turned out to be remarkably productive tools for examining the nature of social preferences and social norms. This paper describes the methods and tools of experimental game theory and provides a selection of games that have been useful. We also discuss the role of evolutionary explanations of and social preference theory in organizing the data in a coherent way.

"This paper studies the role of money in environments where in each meeting there isna double coincidence of real wants. Traders who meet at random finance their purchases through current production, the sale of divisible money or both. It is shown that in the absence of valued money if traders have asymmetric tastes for each other’s good, they produce and exchange socially ine .cient quantities. With valued money, however, traders exchange efficient quantities if the asymmetry of tastes is not too large. It is shown that the gains from trade in the monetary economy are strictly greater than those in the corresponding barter economy, that the Friedman rule holds, and that the allocation of resources in the monetary economy converges to the allocation in the barter economy as the growth rate of the money supply is increased."

We use alternative assumptions about the divisibility of goods and money and thenability of agents to use lotteries on money to investigate to what extent the indivisibility of money is the cause for the typically inefficient production and consumption decisions in search-theoretic models of money. Our framework potentially generates three types of inefficiencies: the no-trade inefficiency, where no trade takes place even though it would be socially efficient to trade; and the too-much-trade and too-little-trade inefficiencies, where the quantities produced and exchanged are either larger or smaller than what the solution to a social planner's problem would mandate. It is shown that while the no-trade and the too-much-trade inefficiencies are caused by the indivisibility of money, the too-little-trade inefficiency remains even when money is divisible unless it is sufficiently valued.
