Constructing panel data estimators by aggregation: A general moment estimator and a suggested synthesis
(Discussion Papers;No. 420, Working paper, 2005)Abstract: A regression equation for panel data with two-way random or fixed effects and a set of individual specific and period specific `within individual' and `within period', estimators of its slope coefficients are ... -
The Distributional impact of public services when needs differ
(Discussion Papers;No. 621, Working paper, 2010)Abstract: Despite a broad consensus on the need to take into account the value of public services in distributional analysis, there is little reliable evidence on how the inclusion of such non-cash income actually affects ... -
How linear models can mask non-linear causal relationships : an application to family size and children's education
(Discussion Papers;586, Working paper, 2009)Many empirical studies specify outcomes as a linear function of endogenous regressors when conducting instrumental variable (IV) estimation. We show that commonly used tests for treatment effects, selection bias, and ... -
Modelling ‘crime-proneness’ : a comparison of models for repeated count outcomes
(Discussion Papers;611, Working paper, 2010)In the criminal career literature, the individual-level age-crime relationship is commonly modelled using generalized linear mixed models, where between-individual heterogeneity is then handled through specifying random ... -
Multivariate stochastic volatility models based on non-Gaussian Ornstein-Uhlenbeck processes : a quasi-likelihood approach
(Discussion Papers;614, Working paper, 2010)This paper extends the ordinary quasi-likelihood estimator for stochastic volatility models based on non-Gaussian Ornstein-Uhlenbeck (OU) processes to vector processes. Despite the fact that multivariate modeling of asset ... -
Non-parametric identication of the mixed proportional hazards model with interval-censored durations
(Discussion Papers;600, Working paper, 2009)This note presents identication results for the mixed proportional hazards model when duration data are interval-censored. Earlier positive results on identication under intervalcensoring require both parametric specication ... -
Optimal control and the Fibonacci sequence
(Discussion Papers;674, Working paper, 2012)We bridge mathematical number theory with that of optimal control and show that a generalised Fibonacci sequence enters the control function of finite horizon dynamic optimisation problems with one state and one control ... -
Trade liberalisation and import price behaviour : the case of textiles and wearing apparels
(Discussion Papers;605, Working paper, 2010)Previous studies on the relationship between exchange rates and traded goods prices typically find evidence of incomplete pass-through, usually explained by pricing-to-market behaviour. Although economic theory predicts ... -
Transitions to disability and rehabilitation
(Discussion Papers;641, Working paper, 2010)The discrete choice model of McFadden (1973) is used to quantify the desire for going into rehabilitation or disability among fully employed married women in Norway. Predictions using the model indicate that as much as 60 ... -
When can micro properties be used to predict aggregate demand?
(Discussion Papers;No. 452, Working paper, 2006)Abstract: Heterogeneity in consumer behaviour creates differences in demand responses, which may create problems with aggregation across consumers. If aggregation problems exist, results from estimation based on aggregate ...
