Business Cycle Phenomena in Overlapping Generations Economies with Stochastic Production

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...

Outcome, Process & Power in Direct Democracy

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...

Motivation, Knowledge Transfer, and Organizational Forms

"Employees are motivated intrinsically as well as extrinsically. Intrinsic motivation is crucial when tacit knowledge in and between teams must be transferred. Organizational forms enable different kinds of motivation and have different capacities to generate and transfer tacit knowledge. Since knowledge generation and transfer are essential for a firm’s sustainable...

External spillovers, internal spillovers and the geography of production and innovation

We consider a three-location duopoly model such that (i) firms choose production and innovation locations before (Bertrand) competition takes place and (ii) there are internal and external knowledge spillovers. We show: (1) agglomerations where firms earn negative profits may exist when there are both external and internal knowledge spillovers; (2) greater external spillovers do not...

Maximising Happiness?

"The measurement of individual happiness challenges the notion that revealed preferences only reliably reflect individual utility. Reported subjective well-being is a broader concept than traditional decision utility; it also includes concepts like experience and procedural utility. Micro- and macroeconometric happiness functions offer new insights on determinants of life...

Demokratieindizes für die Kantone der Schweiz

Die direkte Demokratie ist in den Kantonen der Schweiz unterschiedlich stark ausgeprägt. Die Beteiligung der Bürger im politischen Prozess via Verfassungs- und Gesetzesinitiative, Gesetzesreferendum und Finanzreferendum ist durch verschieden hohe Hürden eingeschränkt. Unterschiede bestehen beispielsweise bei der Anzahl Unterschriften, die verlangt werden, um ein Instrument zu...

Was bewirkt die Volkswirtschaftslehre?

"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”....

Multilaterale Abkommen für Direktinvestitionen - Lernen aus dem MAI?

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....

Innovation and the Emergence of Market Dominance

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...

Ageing of population and health care expenditure: a red herring?

This paper studies the relationship between health care expenditure (HCE) and age, using longitudinal rather than cross-sectional data. The econometric analysis of HCE in the last eight quarters of life of individuals who died during the period 1983-1992 indicates that HCE depends on remaining lifetime but not on calendar age, at least beyond 65+. The positive relationship between...

Fairness, Incentives, and Contractual Choices

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...

On the Nature of Fair Behavior

"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...

Environmental Tax Reform: Efficiency and Political Feasibility

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...

Art Fakes - What Fakes? An Economic View

"An economic analysis of fakes differs substantially from the legal and the art historic views which both tend to propose repressive policies against imitations. But there are large economic benefits from copying. In particular, the ""propagation effect"" yields utility to both consumers and creators of the original. In contrast, the harmful effects of fakes...

Happiness, Economy and Institutions

"A cross-regional econometric analysis is conducted suggesting that institutional factors in the form of direct democracy (via initiatives and referenda) and of federal structure (local autonomy) systematically and sizeably raise self-reported individual well-being. This positive effect can be attributed to political outcomes closer to voters preferences as well as to the...

Do Immigrants Displace Young Native Workers: The Austrian Experience

This paper studies the effect of increased immigration in Austria on the unemployment risk of young natives. Austria experienced a dramatic rise in the share of alien workers as a result of the breakdown of the former commu-nist regimes (especially from former Yugoslavia). We concentrate on unemployment entry of young male workers, who are supposed to compete most heavily with new...

Clever agents in Young's evolutionary bargaining model

In the models of Young (1993, Econometrica61, 57–84; 1993, J. Econ. Theory 59, 145–168), boundedly rational individuals are recurrently matched to play a game, and they play myopic best replies to the recent history of play. It could therefore be an advantage to instead play a myopic best reply to the myopic best reply, something boundedly rational players might conceivably also do....

Does Pay Motivate Volunteers?

Volunteer work is an increasingly large, yet ill-understood sector of the economy. We show that monetary rewards undermine the intrinsic motivation of volunteers. A unique data set from Switzerland allows us to assess the effects of financial rewards on the effort put into volunteer work. There is a fairly standard pattern regarding the volunteers reaction e.g. to more labor market...

Intra-firm Wage Dispersion and Firm Performance

Personnel economics has put forward conflicting arguments concerning the impact of increased wage dispersion within a firm on the productivity of its workers. Besides giving more incentives, bigger wage differentials might also give rise to less co-operation and more politicking amongst workers resulting in worse outcomes. We try to shed light on these issues using panel data for...
