The stochastic frontier analysis (Aigner et al., 1977, Meeusen and van de Broeck, 1977) is widely used to estimate individual efficiency scores. The basic idea lies in the introduction of an additive error term consisting of a noise and an inefficiency term. Most often the assumption of a...

In diesem Artikel wird eine Methode zur Gewinnung von Nutzerfeedback beschrieben, die eine Virtual-Reality-Applikation (VR) als Informationsträger für die Vermittlung der Befragungsinhalte einsetzt. Die Methode wurde im Rahmen des Forschungsprojekts „2049: Zeitreise Mobilität“ des...

When a durable good of uncertain quality is introduced to the market, some consumers strategically delay their buying to the next period with the hope of learning the unknown quality. We analyze the monopolist's pricing and waiting strategies when consumers have strategic delay incentives. We...

We show by Monte Carlo simulations that the jackknife estimation of QUENOUILLE (1956) provides substantial bias reduction for the estimation of short-term interest rate models applied in CHAN ET AL. (1992) - hereafter CKLS (1992). We find that an alternative estimation based on NOWMAN (1997)...

This paper proposes an equilibrium relationship between expected exchange rate changes and differentials in expected returns on risky assets. We show that when expected returns on a risky asset in a certain economy are higher than the returns that are expected from investing in a risky asset in...

The paper discusses global imbalances under the aspect of an asymmetric world monetary system. It identifies the US and Germany as center countries with rising / high current account deficits (US) and surpluses (Germany). These are matched by current account surpluses of countries stabilizing...

This paper investigates the degree of intergenerational transmission of education for individuals from the National Longitudinal Survey of Youth 1979. Rather than identifying the causal effect of parental education via instrumental variables we exploit the feature of the transmission mechanism...

This paper seeks to understand dynamics of inflation and marginal cost (labor share) in models that account for the inclusion of productivity shocks in standard New Keynesian Phillips Curve (NKPC). The question of interest is on the empirical importance of and whether productivity shocks shift...

This paper addresses the various methodological issues surrounding vector autoregressions, simultaneous equations, and chain reactions, and provides new evidence on the long-run inflation-unemployment tradeoff in the US. It is argued that money growth is a superior indicator of the monetary...

While the savings of retired singles tend to fall with age, those of retired couples tend to rise. We estimate a rich model of retired singles and couples with bequest motives and uncertain longevity and medical expenses. Our estimates imply that while medical expenses are an important driver of...
