Business Strategy and the Environment, EarlyView.ABSTRACT This study examines how sustainability performance affects the cost of debt financing in the hospitality and tourism industry and whether institutional environment quality moderates this relationship. Using a dataset of 2302 firm‐year observations from 34 countries between 2010 and 2022, the results show that sustainability performance is ...

New approach to finding eigenvectors for repeated eigenvalues of a matrix
Sistemnì Doslìdženâ ta Informacìjnì TehnologìïAn efficient method of calculating eigenvectors for multiple eigenvalues of a matrix is proposed. This method is based on a formalized transformation of the problem of solving degenerate systems of equations into a regular problem by “repairing” their ...

Environmental Performance Drivers: A Political Cost Approach
Business Strategy and the Environment, EarlyView.ABSTRACT We contribute to the business strategy and the environment literature by examining the effect of political cost pressures on corporate environmental performance in the context of United Kingdom‐listed firms. Drawing on a sample of non‐financial firms from the FTSE All‐Share Index over a period of 10 years (2013–2022), we construct novel ...

Robust Regularized Locality Preserving Indexing for Fiedler Vector Estimation
IEEE Open Journal of Signal ProcessingThe Fiedler vector is the eigenvector associated with the algebraic connectivity of the graph Laplacian. It is central to graph analysis as it provides substantial information to learn the latent structure of a graph. In real-world applications, however,

A Markov approach to credit rating migration conditional on economic states
Canadian Journal of Statistics, EarlyView.Abstract We develop a model for credit rating migration that accounts for the impact of economic state fluctuations on default probabilities. The joint process for the economic state and the rating is modelled as a time‐homogeneous Markov chain. While the rating process itself possesses the Markov property only under restrictive conditions, methods ...
