In this paper we propose a robust Bayesian procedure of estimation, testing, validation and selection of spatio-temporal autoregressive models (STAR) with neighbourhood effects applied to the appraisal of dwelling prices. The methodology does not depend on asymptotic results and, unlike previously procedures proposed in the literature, takes into account the uncertainty associated to the estimation of the neighbourhood parameters of the model, giving more realism to the analysis. Moreover, a sequential algorithm to elaborate fast on-line forecast, is provided. The methodology is illustrated by means of a practical case of the real estate market of Zaragoza. 相似文献

In 1998, the left‐of‐centre government of Hungary carved out a second‐pillar mandatory private pension scheme from the original mono‐pillar public system. Participation in the two‐pillar system was optional for those who were already working, but mandatory for new entrants to the workforce. About 50 per cent of the workforce joined the second pillar voluntarily and another 25 per cent were mandated to do so by law between 1999 and 2010. The second pillar has not improved the financial stability of the social security system. Moreover, the international financial and economic crisis has highlighted the transition costs that are associated with moving, even if only partially, to a system of pre‐funding. In 2010, the conservative government de facto “nationalized” the second pillar, and it is to use part of the accumulated pension capital to reduce Hungary's excessive public debt and annual budget deficit and to compensate for income tax reductions. 相似文献

Objective. To examine the relationship between firm‐level cooperation, inequality, and redistribution in 18 advanced industrialized democracies. Methods. The relationships are investigated using multiple regression analyses of institutional, political, and economic variables. Results. Multilevel models reveal that contrary to neocorporatism, firm‐level cooperative ties have significant inegalitarian effects, particularly in the distribution of pretax, pretransfer market income. The effects, however, are also felt in the distribution of posttax, posttransfer income. Conclusion. By paying attention to the effect of firm‐level cooperation, the study sheds new light on inequality in the OECD as a result of both market‐based and nonmarket coordination. 相似文献

Objective. This study explores whether the earnings of U.S.‐born cross‐border workers differ from those of their U.S.‐employed counterparts. We also analyze whether the cross‐border/non‐cross‐border wage differential changed during the 1990s—a decade when U.S.‐Mexico trade intensified and the maquiladora industry expanded. Methods. Employing decennial U.S. Census data from 1990 and 2000, this article estimates earnings functions and uses wage decomposition analysis to study changes in the earnings of U.S.‐born Hispanic and non‐Hispanic cross‐border workers. Results. The number of U.S.‐native cross‐border workers, while relatively small, increased significantly between 1990 and 2000, as did their earnings. A closer examination reveals that this cross‐border earnings premium only developed among non‐Hispanics. Conclusions. These findings indicate that some U.S. natives find lucrative employment opportunities on the Mexican side of the border, which might be diminished by additional restrictions for U.S.‐born residents to easily cross back and forth into Mexico. 相似文献

This article aims to offer an ex ante evaluation of the impact of a parametric reform of the Spanish pension system that would involve increasing the reference period used to calculate benefits, an approach proposed many times by various actors in the socio‐economic field. Such gradual change may be categorized as a non‐structural reform of the pension system. This contrasts with reforms of a structural nature that have been very popular in Latin America and elsewhere, involving the creation of defined contribution individual account schemes. As regards the parametric reform proposed in this article, the main findings indicate that it would have a small but negative impact on pension income for pensioners and would reduce income distribution. 相似文献

This paper is intended to make a contribution to the ongoing debate about declining social mobility in Great Britain by analyzing mobility tables based on data from the 1991 British Household Panel Survey and the 2005 General Household Survey. The models proposed here generalize Hauser's levels models and allow for a semi-parametric analysis of change in social mobility. The cell frequencies are assumed to be equal to the product of three effects: the effect of the father's position for the given year, the effect of the son's position for the given year, and the mobility effect related to the difference between the father's and the son's positions. A generalization of the iterative proportional fitting procedure is proposed and applied to computing the maximum likelihood estimates of the cell frequencies. The standard errors of the estimated parameters are computed under the product-multinomial sampling assumption. The results indicate opposing trends of mobility between the two timepoints. Fewer steps up or down in the society became less likely, while more steps became somewhat more likely. 相似文献

In this paper, it is demonstrated that coefficient of determination of an ANOVA linear model provides a measure of polarization. Taking as the starting point the link between polarization and dispersion, we reformulate the measure of polarization of Zhang and Kanbur using the decomposition of the variance instead of the decomposition of the Theil index. We show that the proposed measure is equivalent to the coefficient of determination of an ANOVA linear model that explains, for example, the income of the households as a function of any population characteristic such as education, gender, occupation, etc. This result provides an alternative way to analyse polarization by sub-populations characteristics and at the same time allows us to compare sub-populations via the estimated coefficients of the ANOVA model. 相似文献

The purpose of this paper is to develop a Bayesian analysis for the right-censored survival data when immune or cured individuals
may be present in the population from which the data is taken. In our approach the number of competing causes of the event
of interest follows the Conway–Maxwell–Poisson distribution which generalizes the Poisson distribution. Markov chain Monte
Carlo (MCMC) methods are used to develop a Bayesian procedure for the proposed model. Also, some discussions on the model
selection and an illustration with a real data set are considered. 相似文献

The aim of this paper is to analyse the effect of the onset of disability on life satisfaction and five different domains of satisfaction (health, household income, housing, job, leisure) for German individuals. Particular attention is paid to examining whether individuals can adapt to disability over time before and after its onset in terms of satisfaction. Using longitudinal data from the German Socio-Economic Panel (GSOEP) for the period 1984?C2008, we estimate an innovative fixed-effects model on life satisfaction and each domain of satisfaction for working-age males (aged 21?C58), which allows us to estimate lag and lead effects and thus to test the anticipation and adaptation hypotheses. Although individual obtain complete adaptation to disability in terms of global life satisfaction (5?years after the onset), this adaptation is not complete in all domains of satisfaction. For example, despite the fact that the levels of health satisfaction drop as the individual becomes disabled, after the onset it increases but the levels are lower than those reached before the onset. In contrast, the adaptation is especially faster in the terms of leisure satisfaction (3?years after the onset), household income and housing satisfaction (5?years after the onset in both cases). Our results support the findings obtained in other psychological studies that conclude that the domain of disability extends far beyond health related concerns to encompass the person??s well-being definition of self and social position. Finally, these findings may help policy makers and government to promote social and economic measures and actions lead to increase the scores of global well-being and specific domains of satisfaction of this collective. 相似文献
