In this paper we introduce also a concern for efficiency in an social welfare model. We propose a simple but useful specification which combines three features: (i) the selection of measurement instruments in the relative and the absolute case on the grounds of their properties for applied work; (ii) a procedure to make welfare comparisons across households with different needs, in a model in which equivalence scales depend only on household size; an (iii) the use of house hold specific statistical price indices to make intertemporal comparisons in teal terms. The methodology is applied to the study of the role of prices and demographic effects in the evolution of the standard of living in Spain from 1973-74 to 1980-81.

Using data from the National Longitudinal Study of Adolescent Health (Add Health)we analize the influence of high school friends on the coresidence of young adults with their parents. We address the challenges in the identification of peer effects in a static framework and employ an instrumental variable technique and control for state fixed effects in order to mitigate them. We then move to a dynamic framework and exploit differences in the timing of leaving the parental home among peers. Our results indicate that there are statistically significant peer effects on the nest-leaving behavior of young adults.

In equilibrium, capacity is low and underused. Imposing a binding price cap leads to an increase of capacity as well as expected output and total surplus, and to a decrease of expected price. The optimal price cap trades off the incentives for capacity investment and capacity withholding, and is well above the marginal cost. Price cap regulation alone cannot eliminate inefficiencies. When the unit cost of capacity is high the comparative static properties of price caps relative to the price cap than maximizes capacity investment ρ* are analogous to those obtained when the demand is known with certainty, and the optimal price cap is ρ*. When the unit cost of capacity is low, however, the expected output and surplus decrease with the price cap above and around ρ*, and therefore the optimal price cap is below ρ*.

Firstly, a pair of normalization procedures should be compared using their own classification systems for evaluation purposes. Secondly, when the two procedures are noncomparable according to the above test, then evaluation using a third (or more) classification systems may be forthcoming. In the empirical part of the paper we use: (i) the IDCP method for the evaluation of normalization procedures; (ii) two nested classification systems consisting of 219 sub-fields and 19 fields, together with a systematic and a random assignment of articles to sub-fields (or fields) with the aim of maximizing or minimizing differences across sub-fields (or fields); (iii) six normalization procedures using mean citations in each of the classification systems as normalization factors, and (iv) a large dataset, indexed by Thomson Reuters, in which 4.4 million articles published in 1998-2003 with a five-year citation window are assigned to Web of Science subject-categories, or sub-fields using a fractional approach. The results obtained indicate that this methodology may lead to useful conclusions in specific instances. Tue, 30 Apr 2013 22:00:00 GMT http://hdl.handle.net/10016/16672 2013-04-30T22:00:00Z
