"Due to its formality and highly analytic thinking, economics is often attributed a leading role among the social sciences and a prominent position as contributor to economic or social issues in the real world. Fact is, however, that the empirical proof for such a claim is either missing or anecdotal. This paper aims to outline the “economics of economics”. It surveys and compares approaches of impact measurement such as a production function of economics or the demand and supply of trained economists and discusses the determinants of the strength of the influence of economics. It furthermore discriminates between the impact of economic ideas versus that of economists as scientists or politicians."

This paper provides a critical review of the recent literature on inequality and growth. After discussing historical and more recent distributional trends as well as empirical evidence on the relationship between inequality and growth, I focus on recent explanations of the inequality-growth puzzle. I consider both the impact of the functional and the personal distribution on long-run growth rates. A final section discusses a rather neglected issue in the recent literature: the impact of expected demand for innovation decisions.

This paper analyzes economic fluctuations in an overlapping generations economy with productive capital in which random shocks in aggregate productivity are present. Under specific assumptions we obtain an explicit solution of the model. Applying random dynamical systems theory, we can prove that the long-run behavior of the economy is uniquely described by an asymptotically stable random fixed point. The statistical properties of the aggregates output, consumption, capital stock, and real wage are investigated numerically. We find that our artificial economy displays several real world business cycle phenomena.nn

According to the widely used Managerial Power Model, a higher hierarchical position with associated higher power leads to higher compensation. In contrast, the Compensating Wage Differentials Model argues that there is a non-positive relationship between positional power and total compensation. Both power and income yield utility and in equilibrium managers are prepared to trade-off the two elements. The two opposing propositions are tested using a large survey data set from Switzerland. The results suggest that power positions do not yield higher compensation. Rather, there is a non-positive relationship between power position and compensation, if one takes into account all relevant factors influencing total compensation.

Based on survey data for Switzerland, new empirical findings on direct democracy are presented. In the first part, we show that, on average, public employees receive lower financial compensation under more direct democratic institutions. However, top bureaucrats are more constrained in direct democracies and have to be compensated by higher wages for that loss of power. In the second part, we demonstrate that reported subjective well-being of the population is much higher in jurisdictions with stronger direct democratic rights. This is not only the case because people value political outcomes higher but they derive utility from the political process itself.

This paper analyzes a model of oligopolistic competition with ongoing investment. It incorporates the following models as special cases: incremental investment, patent races, learning-by-doing, and network externalities. We investigate circumstances under which a firm with low costs or high quality will extend its initial lead through further cost-reducing or quality-improving investments. In many commonly-studied oligopoly games, such investments are strategic substitutes. We derive a new comparative statics result that applies to games with strategic substitutes, and we use the result to derive conditions under which leading firms invest more than lagging firms. We show that the conditions are satisfied in a variety of commonly-studied oligopoly models. We also highlight plausible countervailing effects from two distinct sources. First, leading firms may find it more costly than others to achieve the same increment to their state. This force is particularly salient inmany models of patentn races, where firms make research investments in an attempt to find a new technology that delivers a given level of cost or quality. Second, countervailing effects may arise in dynamic games with more than two firms are sufficiently patient.

Die Verhandlungen innerhalb der OECD zu einem multilateralen Abkommen ueber Investitionen (MAI) sind gescheitert. Damit werden Direktinvestitionen gegenwaertig weiterhin durch bilaterale Vertraege und durch einige wenige multilaterale Abkommen geregelt. In Zukunft ist jedoch weiterhin damit zu rechnen, daß diese durch ein allgemeines Rahmenwerk nach Vorlage des MAI ersetzt werden. Der vorliegende Aufsatz erlaeutert zunaechst die bestehenden multilateralen Rahmenbedingungen der WTO und der OECD. Anschließend werden die wesentlichen Inhalte des Vertragsentwurfs zum MAI vorgestellt und aus oekonomischer Sicht diskutiert. Ich komme zu der Einschaetzung, daß in einem zukuenftigen Investitionsabkommen (i) wettbewerbspolitische Inhalte, (ii) Ausnahmeregeln in bezug auf wenig industrialisierte Laender und (iii) ein differenzierter Investitionsbegriff enthalten sein sollten. Als Forum fuer ein multilaterales Investitionsabkommen bietet sich die WTO an.

This paper examines how the presence of a non-negligible fraction of reciprocally fair actors changes the provision of incentives through contracts. We provide experimental evidence that principals have a strong preference for less complete contracts although the standard self-interest model predicts that they should prefer the more complete contract. Our theoretical analysis shows that fairness concerns can explain this preference for less completeness. Fair principals keep their promises which provides strong pecuniary incentives through an incomplete contract. Selfish principals free-ride and exploit the agents. Counter-intuitively, selfish agents are induced to work by an incomplete contract while fair agents shirk.

"This paper shows that identical offers in an ultimatum game generate systematically different rejection rates depending on the other offers that are available to the proposer. This result casts doubt on the consequentialist practice in economics to define the utility of an action solely in terms of the consequences of the action irrespective of the set of alternatives. It means, in particular, that negatively reciprocal behavior cannot be fully captured by equity models that are exclusively based on preferences over the distribution of material payoffs. Models that take into account players’ fairness intentions and distributional preferences are consistent with our data while models that focus exclusively on intentions or on the distribution of material payoffs are not."

Command-and-control measures, despite their inefficiencies, are still the standard in environmental policy. This might be due to the fact that command-and-control instruments prevent monetary redistribution between sectors and households and leave property rights on remaining pollution with the emittents. The present paper interprets the no-redistribution policy as a political constraint and investigates on more efficient alternatives to command-and-control, using a computable general equilibrium model for Switzerland. Simulation results render schemes that refund environmental tax revenues by a sector-by-sector-subsidy on labor or output as welfare enhancing.
