In their comment on the article on Uber driver-partners by Jonathan Hall and Alan Krueger, the authors analyze the article’s methodological problems, including sample bias, leading questions, selective reporting of findings, and an overestimation of driver earnings, which do not account for the full range of job-related expenses and is based on outdated data. The authors also argue that Hall and Krueger make unsubstantiated claims that extend beyond the scope of their research and ignore a rapidly growing literature that is critical of the Uber model as well as the broader for-hire vehicle industry in which Uber operates. As policymakers grapple with how to respond to transport network companies, the authors argue that a fuller understanding of the costs and benefits of services such as Uber is critical for making informed policies.

This paper tests whether a wage curve-a negative relationship between unemployment and payexisted in Santiago, Chile during 1957-1996. The analysis is divided into two periods corresponding to the distinct economic models in place in the country. For 1957For -1973, during the period of inward-led development, we reject the existence of a wage curve. The second period, 1974-1996, corresponds to an external opening of the economy and the deregulation of publicly controlled industries and labor relations. For this period, we find a wage curve of -0.08, which is similar to the United States and other western, capitalist economies.Disaggregating the analysis for different groups of workers, we find that since the economic reforms, women's pay falls three times more than men's when unemployment doubles. Also, non-university educated and public sector workers have suffered greater pay decreases from unemployment. Workers in the informal sector do not experience a drop in pay, contradicting the notion that the informal sector acts as a buffer for unemployed formal-sector workers.
