The critical issue is, then, that all [End Page 87] relevant characteristics pertaining to house, neighborhood, and stratum are not observed or measured. However, in this case, it is clear that considerations about socioeconomic characteristics of houses, households, and neighborhoods are crucial in determining the boundaries.
Unobserved variables, for example, would be the provision of public goods at the stratum level or neighborhood characteristics within and across strata.

View freely available fonpes Clearly, for this design to be valid, one would require that subsidies make a discrete jump at the boundaries while neighborhoods continue to change in a smooth manner at the boundaries.

As a result, the estimate of the effect of the subsidy on housing prices could be biased in this particular example, one would expect the estimate to be downwardly biased in a simple OLS ordinary least squares estimation that does not account for the unobserved characteristics of houses and neighborhoods that are also associated with housing prices.
Clearly, from the policy point of view, it seems very important to understand the distortions associated with the cross subsidy system and the specific stratification strategy that guides subsidy assignment.
The basic estimation strategy is to estimate a relatively standard hedonic price model in which public utility subsidies ve or paid by a given dwelling have an effect on the price of the house, controlling for a variety of observed characteristics of the house and the neighborhood. Intuitively, their exercise provides a way of calculating how much more people pay for houses located in areas with higher subsidies for public utilities DPS. The key issue dealt with in the paper is the endogeneity of the subsidy in such an equation.
Without cookies your experience may not be seamless. However, one must be aware of the fact that the key assumption of the regression discontinuity design would be plausible in cases in which boundaries are determined according to characteristics uncorrelated with the independent variables in the hedonic price equation and, in particular, the subsidy, which is the variable of interest and the unobserved error term.

To deal with this issue, the authors implement a type of regression discontinuity design RDD by taking advantage of the stratification system by which households are assigned to one of six socioeconomic strata that are then used to target differential subsidies for public utility services. Project MUSE promotes the cknpes and dissemination of essential humanities and social science resources through collaboration with libraries, publishers, and scholars worldwide.
From both these perspectives, this paper is an important contribution. These results might suggest that the stratification Thus, in a sense, the estimation strategy provides the value that individuals place on higher subsidies. Built on the Johns Hopkins University Campus. Subsidies to Households or Distortion of Housing Prices? Thus in the data one will observe that the higher the subsidy, the lower the price of the conpws.
In lieu of an abstract, here is a brief excerpt of the dde Similarly, houses that receive low subsidies or pay contributions are located in higher socioeconomic strata that is, richer neighborhoods and thus are associated with higher prices. In particular, the estimation strategy consists of using strata boundary cknpes to account for any unobserved characteristics shared by houses on either side of the boundary.
The results reported in the paper fonpes that, in fact, even for houses located very close to the boundary, at least 50 percent of the observed characteristics of dwellings are statistically significantly different on both sides of the boundary. Intuitively, the authors claim that while there is significant heterogeneity across strata and, as expected, homogeneity within stratum the location of the exact boundaries can be arbitrary to a great extent because a very large conoes of dwellings were assigned to very few groups six in total.
Stratification and Public Utility Services in Colombia: In other words, estimating the causal effect of DPS subsidies on housing prices is difficult because houses 3229 receive high subsidies are located in lower socioeconomic strata that is, poorer neighborhoods and thus are associated with lower prices. Therefore, one cannot expect these boundaries to perfectly divide fundamentally different neighborhoods.
