Ayman Tibi أيمن الطّيبي
I am a PhD candidate in Economics at the University of Mannheim. My research interests are in development economics, international trade, industrial policy, and geoeconomics.
I am particularly interested in how economic policies shape development outcomes and firm behavior in developing countries and the EU.
In my work, I create novel datasets, conduct empirical analysis, and develop quantitative general equilibrium models to answer questions.

Abstract
This paper examines how conditional trade policies with input-sourcing requirements affect firms’ exports, production, and labor outcomes. I study Egypt’s Qualifying Industrial Zones (QIZ) program, which grants duty-free access to the U.S. market conditional on sourcing inputs from Israel. I estimate event-study and triple-difference specifications using firm-level customs data, industrial census records, and labor force surveys. I find large and persistent export gains along both intensive and extensive margins alongside improvements in output, productivity, employment, and wages. The improvements are driven by U.S. market access rather than the quality of Israeli inputs. To map these firm-level responses into aggregate and welfare implications, I develop a quantitative heterogeneous-firm trade model with endogenous QIZ compliance, rules-of-origin costs, and productivity upgrading. The framework is used to quantify the program’s economy-wide effects and conduct counterfactual analyses that vary the Israeli content requirement, highlighting the trade-off between lower tariffs and higher input costs.

From Code to Factory Floor: Software Parks and Manufacturing in IndiaWith Tanay Agrawal
Abstract
This project studies whether the expansion of Software Technology Parks in India, introduced to promote IT and software exports, generated spillovers to the manufacturing sector. The question speaks to broader debates on services-led growth, premature deindustrialization, and whether productivity gains in tradable services can complement rather than displace manufacturing in developing economies. I first document that these parks created a large productivity shock in the IT sector in treated districts, and then examine whether this shock affected manufacturing firms using variation across districts and firms in exposure to the parks. In particular, I test whether firms that relied more on software and IT inputs before the policy benefited more from improvements in local IT productivity. To better understand the mechanisms and broader equilibrium implications, I plan to develop a model that can capture how services productivity shocks transmit to manufacturing outcomes.
