Erlebniskommunikation — Vermittlung emotionalen Zusatznutzens

Zunehmende technische Konvergenz führt zu immer ?hnlicheren Produkten auf reifen M?rkten. Auf Basis physischer Produkteigenschaften lassen sich kaum noch Wettbewerbsvorteile erzielen. Anbieter versuchen deshalb gezielt mit ihren Produkten und Marken Mehrwert in Form von emotionalem Nutzen zu schaffen. Eine M?glichkeit, diesen zu transportieren, stellt die neue, innovative Kommunikationsform der Erlebniswelt dar, die bisher insbesondere von Automobilherstellern genutzt wird.     

Does direct democracy make for better citizens? A cautionary warning based on cross-country evidence

It has been shown that both formal existence and actual use of direct democratic institutions have effects on a number of variables such as fiscal policies, quality of governance but also economic growth. Further, it has been argued that direct democratic institutions would not only have an impact on policy outcomes but influence citizen participation and attitudes toward politics. For the first time, these conjectures are tested in a large cross-country sample here. Overall, we do not find strong effects and some of the significant correlations are rather small substantially. In contrast to previous studies, voter turnout is not higher when direct democracy is available or used. Further, and also in contrast to previous studies, citizens do not express a greater interest in politics in countries with direct democracy institutions. Finally, they display lower trust in government and parties but not in parliament. These results shed some doubt on the hope that direct democracy would make for better citizens.     

Econometric forecasts of tourism demand to 2005

A complete system of demand equations which was developed previously to generate forecasts of tourism imports and exports is modified to allow for destination-specific demand structures in the tourism export functions. The new model is shown to be considerably more realistic than the original one, and represents a major conceptual improvement. Furthermore, the modified complete system of demand equations yields more accurate outof-sample forecasts, across both varying time horizons and types of forecast. The new model is used to generate forecasts of tourism imports and exports for 18 countries and various major geographical areas, including the recently expanded European Union, for the period up to 2005 for different scenarios.     

Identifying Laffer Bounds: A Sufficient‐Statistics Approach with an Application to Germany

We derive a simple sufficient‐statistics test for whether a nonlinear tax‐transfer system is second‐best Pareto efficient. If it is not, then it is beyond the top of the Laffer curve and there exists a tax cut that is self‐financing. The test depends on the income distribution, extensive and intensive labor supply elasticities, and income effect parameters. A tax‐transfer system is likely to be inefficient if marginal tax rates are quickly falling in income. We apply this test to the German tax‐transfer system, and we find that the structure of effective marginal tax rates is likely to be inefficient in the region where transfers are phased out.     

Robustness and real consequences of nominal wage rigidity

Nominal wage rigidity has been shown to exist in periods of high inflation, while reduction in nominal pay has been hypothesized to occur in times of low inflation. Nominal wage rigidity would therefore become irrelevant because there is little need to cut nominal pay under high inflation, while the necessary cuts would occur under low inflation. We test this hypothesis by examining Swiss data in the 1990s, where wage inflation was low. Nominal wage rigidity proves robust in a low inflation environment, constituting a considerable obstacle to real wage adjustments. Real wages would indeed respond to unemployment without downward nominal rigidity. Moreover, wage sweep-ups caused by nominal rigidity correlate strongly to unemployment, suggesting downward nominal wage rigidity fuels unemployment.     

ON THE UNIQUENESS OF LIMIT CYCLES IN BUSINESS CYCLE THEORY

Abstract. The paper investigates sufficient conditions for the uniqueness of limit cycles in standard business cycle theory. The application of the Levinson/Smith theorem to the generalized Liénard equation reveals that these sufficient yet not necessary conditions usually imply that the uniqueness of limit cycles in, e.g., the Kaldor-model or the Phillips-multiplier-acceteralor model cannot be established without additional restrictive assumptions.
