The paper provides a niche model for the lack and emergence of ethnic party fragmentation under different demographic conditions. The predictions are tested against the findings of Stroschein (2011) on Hungarian ethnic party success at municipal elections in three Romanian counties.

Imitation of first-mover firms in opting for a merger or acquisition (M&A) facilitates merger-wave formation. Empirical evidence suggests that, under uncertainty of outcomes, firms regret more not following their rivals’ strategy than possibly failing jointly by copying it. We explore the...

Organizational ecology models of market dynamics emphasize the competition-inducing role of inter-organizational niche overlap--targeting similar market niches increases competitive pressure and thus reduces organizations' fitness. Recent studies, however, have suggested that moderate niche...

Chinese employers practice extensive personal screening of job applicants. This study identifies four manifestations of this practice by motive – statistical, customer taste-based, employer taste-based, and regulatory – and evaluates their prevalence, economic determinants and implications...

Real-life utility networks such as smart grids, pipelines and water networks can be exposed to safety and security related risk. Preventative measures can be applied to mitigate such risks that may result in service interruptions for the users of these networks. An index of (dis)connectivity,...

In this paper, the multiple travelling salesperson problem with hotel selection (m-TSPHS) is presented. This combinatorial optimisation problem is a generalisation of both the travelling salesperson problem with hotel selection (TSPHS) and the multiple travelling salesperson problem (m-TSP). As...

In this paper we present a heuristic framework that is based on mathematical programming to solve network design problems. Our techniques combine local branching with locally exact refinements. In an iterative strategy an existing solution is refined by solving restricted mixed integer programs...
