I use data from the South African Social Giving Survey to investigate the role of social capital and motivations for giving to formal charities and beggars. Results suggest that both impure altruism and inequality aversion positively influence giving to formal charities but they have no...

Purpose – This paper aims to examine the association between regulatory capital and risk of Indian commercial banks and the impacts of other relevant variables on them. Design/methodology/approach – The study is based on a secondary data set on Indian commercial banks collected from...

In this paper we analyze Granger causality testing in a mixed-frequency VAR, originally proposed by Ghysels 2012, where the difference in sampling frequencies of the variables is large. In particular, we investigate whether past information on a low-frequency variable help in forecasting a...

We study hypotheses testing in the presence of a possibly singular covariance matrix. We propose an alternative way to handle possible non-regularity in a covariance matrix of a Wald test, using the identity matrix as the weighting matrix when calculating the quadratic form. The resulting test...

This study investigates the impact of innovation support programmes on SME innovation in traditional manufacturing industries in seven EU regions. Recent literature identifying sources of potential government failure in innovation policy suggests that the effects of public support measures to...

In this paper we consider several modified wild bootstrap methods that, additionally to heteroskedasticity, can take dependence into account. The modified wild bootstrap methods are shown to correctly replicate an invariance principle for multivariate time series that are characterized by...

This paper considers estimation of factor-augmented panel data regression models with homogenous slope coefficients. One of the most popular approaches towards this end is the pooled common correlated effects CCE estimator of Pesaran 2006. For this estimator to be consistent at the usual sqrt-NT...

Using innovation survey data on a sample of UK manufacturing firms, Laursen and Salter 2006 documented a non-monotonous relationship between external search strategies and firm-level innovative performance. We find partially similar results in a combined sample of Nigerian manufacturing and...
