This paper presents a generic modeling framework to simultaneously decide about production quantities and maintenance operations for a capacitated resource facing a dynamic demand for di erent types of products. As the resource needs to be setup for each speci c type of product, a lot-sizing...

In this paper, we consider a detailed decomposition method for limited dependent variable models. That means, we propose a method to decompose the differential in the (limited dependent) outcome variable between two groups into the contributions of the explanatory variables. We provide a...

A positive view of the self is often portrayed as a valuable asset in the sense that it can have performance enhancing properties. Using data on self-esteem - the most fundamental manifestation of positive self evaluations - and high school grade point averages of American students we produce...

We set up a three-period overlapping generation model in which young individuals allocate their time to schooling and work, healthy middle aged individuals allocate their time to leisure and work and their income to consumption and savings for retirement, and old age individuals live off their...

Als Teil des operationellen Risikos stellt das Modellrisiko eine wichtige Komponente für die Risikoermittlung bei Finanzinstitutionen dar. Da letztere z.B. bei der Tarifierung und Bepreisung von Derivaten bzw. Portfolien oder bei der Markt- und Kreditrisikoberechnung auf stochastische Modelle...

This paper analyses the effects of discretionary fiscal policy by presenting new empirical evidence for Germany within a structural vector autoregression (SVAR) framework. Following Blanchard and Perotti (2002), the SVAR model is identified by applying institutional information. We find no...

This paper develops a comprehensive endogenous growth framework to determine the optimal mix of growth policies. The analysis is novel in that we capture important elements of the tax-transfer system and fully take into account transitional dynamics in our numerical analysis. Currently, for...

We consider a recently proposed class of nonlinear time series models and focus mainly on misspecification testing for models of such type. Following the modeling cycle for nonlinear time series models of specification, estimation and evaluation we first treat how to choose an adequate...

This paper proposes a model of urban agglomeration in conjunction with imperfect competition and endogenous product R\&D of firms. The quality of differentiated manufacturing goods is a result of R\&D services provided by research firms. Sectoral interactions are subject to spatially dependent...

Previous research on optimal R\& D subsidies has focussed on the long run. This paper characterizes the optimal time path of R\& D subsidization in a semi- endogenous growth model, by exploiting a recently developed numerical method. Starting from the steady state under current R\& D...
