The sharing economy model of Uber has been replicated in other similar areas. Ride sharing economy gave birth to food and grocery delivery systems. Uber launched a food-ordering app called UberEATS which not only allows users to order food, but also enables users to register to be UberEATS drivers. Similar to Uber drivers, UberEATS drivers get paid for delivering food.  An example of grocery delivery in sharing economy is Instakart. It has the same business model as that of sharing economy based companies like Uber, Airbnb, or CanYa.  Instacart uses resources that are readily available, and the shoppers shop at existing grocery shops. The contract workers use their personal vehicles to deliver groceries to customers. Instacart manages to keep its cost low as it does not require any infrastructure to store goods. In addition to having contract workers, Instacart allows signing up to be a "personal shopper" for Instacart through its official web page.  
In Texas, black and Hispanic students tend to enter school with lower initial achievement. Does this matter? Hoxby finds that it does. Students who are exposed to unusually low achieving cohorts tend to score lower themselves. Interestingly enough, black students appear to be particularly affected by the achievement of other black students. Hispanic students appear to be particularly affected by the achievement of other Hispanic students. In fact, Hispanic students do better when in majority Hispanic cohorts, even though the additional Hispanic students tend to have lower initial achievement. It may be that in classes with more Hispanics, a student who is learning English is more likely to find a bilingual student who helps him out.
