There is a growing interest in deriving value from user-generated comments and reviews online. For businesses and consumers using online platforms, the reviews serve as quality metrics and influence consumers purchasing decision. This study examines the relationship between guests reviews, used as a proxy for quality, and the price set by hosts on the Airbnb platform in Boston. Using sentiment analysis to derive the quality from the reviews and a hedonic spatial autoregressive model applied to rental room prices on Airbnb, we find that prices are strategic complements and are influenced by the review score, the characteristics of the room, and the features of the neighborhood. The marketing implication is that consumers respond to the contents of online reviews, in addition to customer ratings. Policies that improve the quality of the room for one host will have a spillover effect on the price of rooms offered by other hosts.  
Immigration Reform and Farm Labor Markets -- Timothy J. Richards

Farmers throughout the United States report a shortage of workers. At the same time, there are proposals to strengthen the enforcement of existing immigration laws. In this paper, we develop an equilibrium approach to examine the impact of removing undocumented workers from the California agricultural labor market and to infer whether there is evidence of shortages using individual-worker data. We find evidence that is consistent with a persistent shortage in some sub-sectors of the California farm labor market. Further, we find that removing all undocumented farm workers from the state would lead to a nearly 50% increase in wages.

This paper estimates how household-level water consumption may be impacted by the distribution of Home Water Use Reports (HWURs) by Dropcountr (DC), a digital and web-based consumption analytics platform. Similar to Opower in the energy sector, DC offers a social comparison, consumption analytics, and conservation information to residential accounts, primarily through digital communications. In this paper, we use daily data from January-2013 to May-2017 from a mid-sized California water utility and monthly data from May-2012 to May-2017 from a major utility in the southwest of the United States. Results indicate an economically and statistically significant 5−15% and 3−13% reduction in average daily household water consumption for the California and the southwest utility, respectively, for the typical household under treatment of the DC program. We observe significant variation in the DC`s effect across households’ dependent on the baseline consumption quintile for both utilities. Furthermore, results suggest that the effect of DC varies by the number of months being in the program, the day of the week, quartile of the year, message type, and enrollment wave. Early findings indicate these responses to DC program is coming from the moral suasion channel rather than information.
Bio-fuels, Price Supports, and Urban Growth in the American -- Dr. William Hoyt

This study provides evidence of the impact of agricultural rent on urban growth. We measure the opportunity cost of land by the annual weighted revenue and cost per acre of farm land, which are based on price, cost, land used, and productivity data on nine major agricultural commodities at county levels in U.S. We estimate that urban population will be 1.8% percent lower when agricultural revenue doubles, and 1.3% higher when agricultural cost doubles; urban population growth rate will be 1.1 (0.6) percent point lower (higher) when agricultural revenue (cost) doubles. These estimates of the impacts agricultural revenues and costs on urban growth, as well as the impacts of government subsidies, are then used to simulate the impacts of changes in governments subsidies, bio-fuel subsidies, and technological change in agriculture on urban growth .
Household Consumption Responses to SNAP Participation -- Shaheer Burney

Obesity is inordinately prevalent among food insecure households in the US. Some researchers have identified the consumption of unhealthy food as one of the sources of this seemingly paradoxical relationship. One of the goals of the Supplemental Nutrition Assistance Program (SNAP), formerly known as the Food Stamp Program, is to encourage healthy eating behavior among low-income households. However, literature lacks conclusive evidence for the success of the program in achieving that goal. This paper exploits an underutilized source of variation, the early-2000s recession in the US, to determine the impact of SNAP participation on household Food Away From Home (FAFH) expenditures. A difference in difference model is constructed using high post-recession growth in SNAP caseloads as treatment. The results show that households in the treatment cohort significantly decrease consumption of FAFH relative to households in the control group after the early-2000s recession. This provides evidence that SNAP participation may lead households to make healthier eating choices.
