摘要：
Many on-demand platforms use crowdsourced contractors to meet customer demand for service. For example, ride-hailing platforms such as Uber and Lyft rely on free-lance drivers who decide when and how long to work by themselves. Those platforms set two critical controls, i.e., the price they charge the customers and the wage they pay the service providers, in a centralized and dynamic manner This allows them to balance demand and supply under varying market conditions. Even though both price and wage may be adjusted dynamically as the market condition changes, in practice it is common for platforms to charge a flat, across-the-board commission that applies to all market conditions.
In this paper, we study the price and wage decisions of such a platform and the performance of the fixed commission contract (or FCC in short, measured by the fraction of the optimal expected profit it can achieve). We show that the performance of FCC is determined by the dispersion of the demand and supply elasticities (with respect to the price and wage, respectively) in different market conditions. Further, we provide a lower bound on its performance as a function of those elasticities. In the special case where supply is a concave function of the wage, we show that the best FCC achieves at least 75% of the optimal expected profit. Our theoretical bounds also enable us to evaluate the worst-case performance of the fixed commission contract based on the empirical findings in the economic literature on demand and supply elasticities for ride-hailing services.
We then study several extensions of the model. We consider the model with price-setting suppliers (instead of letting the platform set the price) and the model with long-term committed suppliers (whose surplus is determined by the long-run average earnings across different market conditions). For both models, we show that our main result remains valid. We also consider an extension where the platform maximizes the supply side surplus or the social welfare. We show that when the platform makes an effort to improve the welfare on the supply or demand side, the other side tends to be benefitted as well.
