In lieu of an abstract, here is a brief excerpt of the content: 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.
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.
Intuitively, the authors claim that while there is significant heterogeneity across strata conles, as expected, homogeneity within stratum the location of the exact boundaries can be arbitrary to a great extent because a very large number of dwellings were assigned to very few groups six in total.

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.

Thus the authors argue that it is plausible to expect characteristics of households and neighborhoods to be quite similar at the boundaries. Thus in the data one will observe that the higher the subsidy, the lower the price of the house. The critical issue is, then, that all [End Page 87] relevant characteristics pertaining to house, neighborhood, and stratum are not observed or measured.

Unobserved variables, for example, would be the provision of public goods at the stratum level or neighborhood characteristics within and across strata. Built on the Johns Hopkins University Campus. Subsidies to Households or Distortion of Housing Prices?
The results reported in the 204 indicate that, in fact, even for houses located very close to conpfs boundary, at least 50 percent of the observed clnpes of dwellings are statistically conpe different on both sides of the boundary. 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.

Stratification and Public Utility Services in Colombia: From both these perspectives, this paper is an important contribution.
In particular, the estimation strategy consists of using strata boundary dummies to account for any unobserved characteristics shared by houses on either side of the boundary. 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. Thus, in a sense, the estimation strategy provides the value that individuals place on higher subsidies.
Therefore, one cannot expect these boundaries to perfectly divide fundamentally different neighborhoods. Forged from a partnership between a university press and a library, Project MUSE is a trusted part of the academic and scholarly community it serves. 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.

In other words, estimating the causal effect of DPS subsidies on housing prices is difficult because houses that receive high subsidies are located in lower socioeconomic strata that is, poorer neighborhoods and thus are associated with lower prices.
