Der Beitrag schildert die Effekte von Antwortausfällen bei einzelnen Fragen ("item non-response") auf die Ergebnisse von multivariaten statistischen Analysen. Dabei wird das Verfahren der "Data Augmentation" angewendet, um die fehlenden Daten zu ersetzen (Schafer 1997). Anhand von Schätzungen...

This paper considers two models to deal with an outcome variable that contains a large fraction of zeros, such as individual expenditures on health care: a sample-selection model and a two-part model. The sample-selection model uses two possibly correlated processes to determine the outcome: a...

This paper demonstrates the application of Bayesian simulation-based estimation to a class of interest rate models known as Affine Term Structure (ATS) models. The technique used is based on a Markov Chain Monte Carlo algorithm, with the discrete observations on yields augmented by additional...

Der Beitrag schildert die Effekte partieller Antwortverweigerung auf die Ergebnisse multivariater statistischer Analysen anhand von Produktivitätsschätzungen auf Betriebsdatenebene. Als Datenbasis dient das IAB-Betriebspanel aus dem Jahr 2000, wobei fehlende Daten mit Hilfe des "Data...

A dynamic Tobit model with Time-varying parameters is proposed for the daily reaction function of the Open Market Desk of the US Federal Reserve. Such a model offers a more realistic depiction of the Desk's behavior than those of past contributions in the literature as it allows for both...

This paper provides an empirical analysis of a range of alternative single-factor continuous time models for the Australian short-term interest rate. The models are indexed by the level effect parameter for the volatility in the short rate process. The inferential approach adopted is Bayesian,...

Most macroeconomic indicators failed to capture the sharp economic fluctuations during the Corona crisis in a timely manner. Instead, alternative high-frequency data have been used, aiming to monitor the economic situation. However, these data are often only loosely related to the business cycle...
