the paper presents an analysis of both energy intensity and energy demand for the italianindustrial sector. the aim of the paper is twofold: making a decomposition of energy intensity at the aggregate level and modeling energy demand at the firm level. the decomposition of energy intensity shows different patterns for the different sub-sectors in the period of interest. in the micro approach, p...

Drug abuse inflicts considerable harm on users, non-using persons and on society, and a variety of means to curtail consumption of illegal drugs have been adopted. The consumption of drugs differ from consumption of most other goods in that it involves addiction. Inter-temporal models are needed to encompass this aspect. The data for this study have been collected through interviews with heroin...

This paper studies panel quantile regression models with endogeneity and additive fixed effects. We focus on static panel model where regressors and instruments are not predetermined. The fixed effect approach causes an incidental parameter bias in the estimates of the parameters of interest, and we characterize this bias under an asymptotic where both panel dimensions become large. We encounte...

The commitment to public health insurance for children has increased in recent years, leading to two potentially contradictory concerns for public policy: that expanded availability of public insurance may lead families to decline private insurance for their children and that the additional public coverage may not reach many children without insurance. We use data from the 1987-1993 Surveys of ...

A new approach for analyzing state duration data in brand-choice studies is explored. This approach not only incorporates the correlation among repeated purchases for a subject, it also models the purchase timing and the brand decision jointly. The former is accomplished by applying transition model approaches from longitudinal studies while the latter is done by conditioning on the brand choic...

Abstract Purpose: This study investigates the effect of investment in intellectual capital and its components on performance Brazilian companies listed Brasil, Bolsa, Balcão (B3) exchange. More specifically, we examine whether a positive relationship exists between proxies for intellectual, structural, human, invested firms’ return assets equity. Originality/value: differs from those Richieri (...
