williamsProf Colin Williams, GREY Project coordinator, School of Management


Colin Williams is Professor of Public Policy and joined the Management School at the University of Sheffield in September 2006. Prior to this, he was a professor in the School of Management at the University of Leiceste
Colin’s broad research interests are in re-theorising the nature of economic development and investigating the implications for public policy. Spatially, his interests range across the full spectrum from local and regional economic development in the UK through to the restructuring of western economies, post-socialist societies and the third (majority) world. Much of his work focuses upon rethinking the meanings of ‘economic’ and ‘development,’ which directly feeds into the work of the Centre for Regional Economic and Enterprise Development (CREED). Colin’s particular research interest is in studying the magnitude and character of the informal economy and evaluating different public policy approaches and initiatives for tackling this sphere.
Colin currently serves as Editor of The International Journal of Sociology and Social Policy and the International Journal of Community Currency Research.

Marijana-BaricMarijana Baric

Marijana is a final year Management PhD student researching the extent and nature of undeclared work in Croatia. Her PhD focuses on developing a theoretical framework for studying undeclared work from a social exchange perspective. Such an approach allows the investigation of both the government/citizen relationships as well as the interactions and networks of the workers themselves. She chose Split in Croatia as her research context as that is where she is originally from. Marijana was recently involved in a project funded by the European Foundation of the Improvement of Living and Working Conditions where the outcome was producing national reports of undeclared work and how it is being tackled in Croatia and 4 EU candidate countries.
Broadly she is interested in social exchange theory and how it can be reconceptualised and used to study a variety of work-based and social situations. Although her work focuses mainly on policy she is also interested in many aspects of organisational behaviour and HRM research.

marinaMarina Polak

Marina Polak is an early stage researcher and a second year Management PhD student at the University of Sheffield. Prior to her PhD, Marina obtained a Bachelor’s degree in Management from the University of Sheffield. Her current research is looking at the nature and characteristics of undeclared work in Slovenia, as well as the use of social networks in the informal sphere. She is particularly interested in both paid and unpaid favours and the use of informal networks.  She is very keen to find out how widely people still rely on informal networks to get things done in comparison to other post-socialist countries, as well as the unwritten rules and expectations that apply between two parties involved in an informal transaction. She chose to do her research within the context of Celje, Slovenia as that is where Marina is originally from. Although Marina’s work mainly focuses on policy implications, she is also interested in many other aspects of HRM research.
