With a view to the unconventional monetary policy measures implemented in the euro area in recent years, this study aims to investigate whether the recent house price increases in Germany are signals of an incipient overheating of the German housing market.

This paper presents a valuation measure for residential property based on a large and exhaustive regional panel data set for Germany. The fitted house prices from a panel regression at the district level, taking into account spatial spillovers, are taken as a measure of the fundamental equilibrium house prices, which can be aggregated for various regional subsets.

The estimation results suggest that apartment prices over the past years substantially exceeded the fundamental price suggested by the model, in particular in the big cities. Single-family houses appear to be markedly overvalued mainly in the cities. The low level of interest rates in recent years appears to have contributed to the emergence of misalignments.

Exploiting the variation across local housing markets, the estimation approach provides value-add for the estimation of house price valuation results in various regional subsets, as conventional time-series approaches to valuing property are subject to severe data limitations in the case of Germany.

Drawing on the International Auditing and Assurance Standards Board (IAASB) audit quality framework and related knowledge management literature, this study aims to examine the influence of tacit knowledge sharing on audit quality inputs within small audit firms’ realm. It also investigated auditors’ social capital antecedent effect via tacit knowledge sharing on audit quality inputs.

An integrated model was developed to depict the study constructs’ relationships. The model was then tested using the partial least squares structural equation modelling based on data collected from auditors belonging to small audit firms in Jordan.

The results indicate that tacit knowledge sharing influences positively the auditors’ values, ethics, attitudes, experiences, skills and knowledge (i.e. audit quality inputs). This finding implies that active tacit knowledge sharing within a small audit firm is a strong driver for audit quality through improving its inputs. The results also demonstrate that structural, relational and cognitive social capital indirectly affect audit quality inputs through tacit knowledge sharing. Accordingly, social capital can be viewed as an audit firm resource that can smooth auditors’ tacit knowledge-sharing progress.

The IAASB encourages audit firms to explore ways to boost audit quality. This study offers empirical evidence on the influence of tacit knowledge sharing on audit quality inputs as a way to boost audit quality. It also offers insights into the value of social capital dimensions and indicates the driving forces to make auditors willing to engage in tacit knowledge sharing and, as a result, improve audit quality inputs.

The purpose of this paper is to investigate how new technology-based firms (NTBFs) overcome established notions of scale and scope through business model innovation, leveraging the value from digitalization.

The study adopts an exploratory research design, drawing on a novel data set of 50 publicly available interviews with vertical farming (VF) industry leaders and insiders who represent 36 different organizations from North America and Europe.

The study develops a framework showing how NTBFs leverage the value from digitalization via a paradoxical approach combining both efficiency and novelty value drivers.

The study extends current theorizing on the desirability of a combined business model approach leveraging both efficiency and novelty from digitalization. Furthermore, the study is among the first to investigate the unique and highly technological context of VF.

Procuring relief products and services is a challenging process for humanitarian organizations (HOs), yet it accounts for approximately 65% of relief operations’ costs (Moshtari et al., 2021). This paper aims to examine how procurement internal controls, materials and purchasing procedure standardization influence information integration and procurement performance.

In this study, partial least square structural equation models and multigroup analysis were used to analyze data collected from 170 HOs.

Procurement internal controls and material and purchasing procedure standardization fully mediate between information integration and procurement performance.

The study focuses only on HOs. Since humanitarian procurement projects take place over a period of several years, it is difficult to capture the long-term effects of information integration, procurement internal controls, material and purchasing procedure standardization and procurement performance. In this regard, a longitudinal study could be undertaken, provided that the required resources are available.

Procurement managers should implement information integration practices within acceptable procurement internal controls and standardize material and purchasing procedures to boost procurement performance.

By integrating information through procurement internal controls and standardizing material and purchasing procedures, procurement performance in a humanitarian setting can be systematically optimized.
