Based on a stochastic dynamic model of a firm’s optimal innovativebehavior we derive a simultaneous equation system for product andprocess innovations with intertemporal spillover effects. We estimatevarious versions of the model with dichotomous innovation data at thefirm level by using a...

The production index is an important indicator for assessing the cyclical state of the economy. Unfortunately, the monthly time series is contaminated by many noisy components like seasonal variations, calendar and vacation effects. Only part of those nuisance components are explicitly...

This paper presents a dynamic random effects probit model for the realization of private firms’ product and process innovations. We estimate the model with panel data collected by the Ifo Institute in Munich. The data covers the period between 1979 and 1986 and includes 301 firms of the West...

This paper deals with the residential demand for electricity. A theoretical model is formulated which is based on intertemporal optimization in a household production context. The model is estimated using a dynamic version of the PLS (partial-least-squares) approach. Most important determinants...

We test the hypothesis of a negative long-term trend and/or a structural break in total factor productivity (TFP) after the first oil price shock for West German manufacturing industries within an econometric model based on a flexible cost function with capital as a quasi-fixed factor. After...

We examine the economic and social determinants of suicide mortality in a panel of 25 OECD countries over the period 1970 - 2011 and explicitly analyze the effects of unemployment and labor market institutions on suicide rates. In line with a large body of literature, our results suggest that...
