Peritoneal dialysis (PD) as a modality is underutilized in most parts of the world today despite several advantages including the possibility of it being offered in the remotest of locations and being significantly more affordable than haemodialysis (HD) in most cases. In this article, we will compare the cost of HD and PD in several countries to demonstrate that PD is less than, or at least as expensive as, HD. A thorough literature survey of EMBASE and PUBMED was conducted; 78 articles which compared the annual PD and annual HD costs were finally selected. Careful attention was paid to the methodology followed by each study and the year it was published in. Our final calculations included 46 countries (20 developed and 26 developing). We found that the cost of HD was between 1.25 and 2.35 times the cost of PD in 22 countries (17 developed and 5 developing), between 0.90 and 1.25 times the cost of PD in 15 countries (2 developed and 13 developing), and between 0.22 and 0.90 times the cost of PD in 9 countries (1 developed and 8 developing). From our analysis, it is evident that most developed countries can provide PD at a lesser expense to the healthcare system than HD. The evidence on developing countries is more mixed, but in most cases PD can be provided at a similar cost where economies of scale have been achieved, either by local production or by low import duties on PD equipment.

Terms of use: Documents in AbstractIn this paper we investigate the size of the consumption drop at retirement in Italy. We use micro data on food and total non-durable household spending covering the period 1993-2004, and evaluate the change in consumption that accompanies retirement by exploiting the exogenous variability in pension eligibility to correct for the endogenous nature of the retirement decision. We take a regression discontinuity approach, and make the identifying assumption that consumption would be the same around the threshold for pension eligibility if individuals would not retire. We check in our data that a non-negligible fraction of individuals retire as soon as they become eligible, and estimate at 9.8% the part of the non-durable consumption drop that is associated with retirement induced by eligibility. We show that such fall is not driven by liquidity problems for the less well off in the population, and can be accounted for by drops in goods that are work-related expenses or leisure substitutes. However, we also show that retirement induces a significant drop in the number of grown children living with their parents, and this can account for most of the retirement consumption drop.

Many students enrolled in academic programs around the world take longer to obtain a degree than the normal completion time while college tuition is typically constant during the years of enrollment. In particular, it does not increase when a student remains in a program beyond the normal completion time. Using a Regression Discontinuity Design on data from Bocconi University in Italy, this paper shows that an increase of 1,000 euro in the continuation tuition reduces the probability of late graduation by at least 6.1 percentage points with respect to a benchmark average probability of 80%. We conclude suggesting that an increase in continuation tuition is efficient when effort is suboptimally supplied, for instance in the presence of public subsidies to education, congestion externalities and/or peer effects.

In a sharp regression-discontinuity design (RDD) the participation status deterministically depends on whether a preprogramme characteristic is above or below a specified threshold. The attractiveness of such a design rests on close similarities with a formal experiment. Nevertheless, it is of limited applicability since participation into a programme is seldom determined according to this rule. Besides, in the presence of heterogeneous effects a sharp RDD only allows identification of mean effects for individuals around the threshold for participation. Two results are presented in this paper, and they both partially overcome the two limitations described above. We show that when individuals self-select into participation conditional on some eligibility criteria a sharp RDD provides a natural framework to define a specification test for the non-experimental estimation of programme effects for participants away from the threshold. We also show that, in this set-up, the regularity conditions required for the identification of the mean counterfactual outcome for participants marginally eligible for the programme are essentially the same as in a sharp RDD. r 2007 Elsevier B.V.
