This research project explores the future of the sharing economy and its profound effects on housing markets, white-collar labor dynamics, and socio-economic challenges in large metropolitan areas. Using quantitative economics and econometric techniques, the study evaluates how platforms such as Airbnb, Uber, and coworking spaces are reshaping urban life, exacerbating housing affordability issues, and altering labor market structures. By analyzing housing market data, labor statistics, and platform economy data from major cities like New York, London, and Istanbul, this research provides empirical insights into how the sharing economy influences urban economic landscapes. The study employs difference-in-differences (DiD) and multivariate regression models to assess causal relationships, particularly in terms of housing market disruptions caused by short-term rental platforms and labor market fragmentation driven by the rise of gig and remote work. Spatial econometric techniques are also used to explore geographic disparities in housing and employment impacts across urban districts. Preliminary findings indicate that the proliferation of sharing economy platforms has contributed to housing shortages and increased prices in central urban areas, while labor markets experience growing polarization, with high-skilled workers benefiting from remote work opportunities and low-skilled gig workers facing economic precarity. This research offers valuable policy insights into the regulation of short-term rentals and the protection of gig economy workers, highlighting the need for regulatory frameworks that address urban inequality and labor market shifts. By integrating data from multiple sources, this study contributes to the academic discourse on urban economics and provides a framework for understanding the long-term socio-economic implications of the sharing economy in big cities.
