Business cycle indicators are used to assess the economic situation of countries or regions. They are closely watched by the public, but are not easy to interpret. Does a current movement of the indicator signal a turning point or not? With the help of Markov Switching Models movements of...

Investment in equipment and machinery is a very important component of GDP. In this paper we examine whether data from business tendency sur- veys are useful for a timely assessment of current investment behavior. In addition we investigate whether the survey results are helpful for forecasting...

Business tendency surveys are a commonly accepted instrument for the assessment of the current business cycle course. Most of these surveys rely on qualitative questions about the current situation of the firms and about heir expectations for the next months. This paper analyzes whether...
