Statistical Analysis in surveys is often facing missing data. As case-wise deletion and single imputation prove to have undesired properties, multiple imputation remains as a measure to handle this problem. In a longitudinal study, where for some missing values past or future data points might...

Recent years have seen an unprecedented increase in the provision of R&D tax incentives. A growing empirical literature suggests that R&D tax incentives are instrumental in raising domestic R&D activity. In policy debates this fi nding is often interpreted to lend support to the notion that R&D...

We study the effect of railroad access on urban population growth. Using GIS techniques, we match triennial population data for roughly 1,000 cities in nineteenth-century Prussia to georeferenced maps of the German railroad network. We find positive short- and long-term effects of having a...

In this paper we explore the possibility of the application of GAMLSS regression techniques for the analysis of income distributions in Germany following the reunification. We find that conditional income distributions can generally be modelled using the three parameter Dagum distribution and...

Based on the Canadian National Population Health Survey we estimate the effects of individ-ual sports and exercise on individual labor market outcomes. The data covers the period from 1994 to 2008. It is longitudinal and rich in life-style, health, and physical activity in-formation. Exploiting...

We study for a sample of international mergers and acquisitions the effectiveness of three takeover bidding strategies first in preventing bidder contests and second, if a contest has occurred, in increasing the probability of a successful offer. Our results indicate that support for the...

In this study, we examine how the interaction between monetary policy and macroeconomic conditions affects inflation uncertainty in the long-term. The unobservable inflation uncertainty is quantified by means of the slowly evolving unconditional variance component of inflation in the framework...

Using data from social security records on Spanish males, we investigate the wage effects of working under a fixed-term contract. In a first step, we provide fixed-effects estimates of the wage effect of working under a fixed-term contract for low-skilled, medium-skilled, and high-skilled men...

This paper provides a systematic analysis of individual attitudes towards ambiguity, based on laboratory experiments. The design of the analysis allows to capture individual behavior across various levels of ambiguity, ranging from low to high. Attitudes towards risk and attitudes towards...

Several formal methods have been proposed to check identification in DSGE models via (i) the autocovariogram (Iskrev 2010), (ii) the spectral density (Komunjer and Ng 2011; Qu and Tkachenko 2012), or (iii) Bayesian indicators (Koop et al 2012). Even though all methods seem similar, there has been no...
