Research / Scholarly interests

Edna's research examines the effect of foreign direct investment (FDI) and the multinational firm on economic growth and firm level productivity. She is interested in growth economics which, in her view, is the first step to improving the wellbeing of societies. Edna is also interested in the determinants of firm productivity, being an important contributor to economic growth. Her empirical research involves the use of panel datasets – hence, she is interested in applied panel data econometric methods.

Key funded projects

ESRC project, Evaluation of R&D expenditures, firm survival, firm growth and employment: UK evidence in OECD context, with Prof Mehmet Ugur (lead researcher), Dr Eshref Trushin (Durham university) and Dr Francesco Guidi. June 2013 to December 2014.

The research aims to investigate the effectiveness of the UK R&D tax credits policy on R&D expenditures and to examine the effect of R&D expenditures on firm survival, productivity and employment. The first part of the research aims to examine whether R&D policy is of value to the taxpayer by investigating whether it has achieved its purpose of increasing R&D effort of UK firms. The second part examines whether R&D expenditure by firms affects firm survival, productivity and employment. If R&D expenditures are key determines of firm survival and growth, then a policy implication is that R&D expenditures must be stimulated.
