The Duration of Immigrants? Unemployment Spells: Evidence from Sweden
Hansen, Jörgen - 2000
Using a proportional hazard model with multiple exits, this paper analyzes whether immigrants' unemployment spells differ from natives', and if so, how the difference vary with time spent in Sweden and across immigrant cohorts. A unique data set taken from the Swedish unemployment registers is...

The effect of protest votes on the estimates of willingness to pay for use values of recreational sites
Strazzera, Elisabetta; Genius, Margarita; Scarpa, Riccardo - 2001
Selectivity bias caused by protest responses in Contingent Valuation studies can be detected and corrected by means of sample selection models. This paper compares two methods: the Heckman 2-steps method and the full ML, applied to data on forest recreation - where WTP is elicited as a...

Recurrent support vector regression for a nonlinear ARMA model with applications to forecasting financial returns
Chen, Shiyi; Jeong, Kiho; Härdle, Wolfgang Karl - 2008
recurrent SVR is compared with three competing methods, MLE, recurrent MLP and feedforward SVR. Theoretically, MLE and MLP only … metrics (NSME and sign). That is, for one-step-ahead forecasting, the recurrent SVR is consistently better than the MLE and …

Marshall-Olkin Power Lomax distribution for modeling of wind speed data
Ul Haq, Muhammad Ahsan; Rao, G. Srinivasa; Albassam, … - In: Energy Reports 6 (2020), pp. 1118-1123
Accurate collection of wind speed records is significant for numerous wind power applications. The present investigation aims to highlight the use of the Marshall-Olkin Power Lomax (MOPLx) distribution for wind speed data. We examine the actual wind speed records gathered from three stations...

Hidden Markov model for stock selection
Nguyen, Nguyet; Nguyen, Dung - In: Risks 3 (2015) 4, pp. 455-473
The hidden Markov model (HMM) is typically used to predict the hidden regimes of observation data. Therefore, this model finds applications in many different areas, such as speech recognition systems, computational molecular biology and financial market predictions. In this paper, we use HMM for...

Heteroskedasticity of unknown form in spatial autoregressive models with a moving average disturbance term
Doğan, Osman - In: Econometrics 3 (2015) 1, pp. 101-127
In this study, I investigate the necessary condition for the consistency of the maximum likelihood estimator (MLE) of … spatial models with a spatial moving average process in the disturbance term. I show that the MLE of spatial autoregressive … estimation. I also show that the MLE of parameters of exogenous variables is inconsistent and determine its asymptotic bias. I …

Microstructure noise in the continuous case: the pre-averaging approach
Jacod, Jean; Li, Yingying; Mykland, Per A.; Podolskij, Mark - 2007
This paper presents a generalized pre-averaging approach for estimating the integrated volatility. This approach also provides consistent estimators of other powers of volatility in particular, it gives feasible ways to consistently estimate the asymptotic variance of the estimator of the...

Preferences under ignorance
Gossner, Olivier; Kuzmics, Christoph - 2015
A decision maker (DM) makes choices from different sets of alternatives. The DM is initially fully ignorant of the payoff associated to each alternative, and learns these payoffs only after a large number of choices have been made. We show that, in the presence of an outside option once payoffs...
