Research Interests

Dr. Geylani develops economic models of firm behavior, finds new ways to evaluate firms' performance measures (i.e., productivity and efficiency), and analyzes large databases.

As an applied econometrician and micro-economist, her research uses a variety of methods, ranging from analysis of secondary data which involves analyzing firm performance measures using large panel databases of establishments and firms (e.g., US Census Bureau, ORBIS, Compustat, and KLD databases) to developing and analyzing surveys.

Her research is multi-disciplinary, using economics, business, and statistics theories, and is multi-level, examining economic behavior at the plant, firm, and industry/aggregate levels. 

Dr. Geylani’s training in applied microeconomics, environmental economics and econometrics has allowed her to channel research efforts into three main categories: (1) economics of productivity, efficiency, and innovation, (2) environmental economics, and (3) microeconomics of trade and investment.

She also investigates how innovation and technological change play a role in a firm's production decisions and analyzes the impact of the firm's involvement in international trade on its product mix, productivity, efficiency, cost structure and innovation.

Additionally, she examines environmentally friendly technical changes that alleviate a firm's existing polluting activities, designs effective policy instruments which lead to better outcomes for both the environment and producers, and analyzes the effect of corporate social responsibility on shareholder wealth.
