Out of Africa : what drives the pressure to emigrate?
Dalen, Hendrik P. van; Groenewold, George; Schoorl, … - 2004
This paper evaluates the strength of social and economic forces that affect the pressure to emigrate 'out of Africa' for four distinctly different African countries (Morocco, Egypt, Senegal and Ghana). In general, great expectations about attaining a higher living standard and expected low job...

Remittances and their effect on emigration intentions in Egypt, Morocco and Turkey
Dalen, Hendrik P. van; Groenewold, George; Fokkema, Tineke - 2005
What determines remittances – altruism or enlightened self-interest - and do remittances trigger additional migration? These two questions are examined empirically in Egypt, Turkey and Morocco for households with family members living abroad. Results show, first, that one cannot clearly...

The effect of the great moderation on the US business cycle in a time-varying multivariate trend-cycle model
Creal, Drew; Koopman, Siem Jan; Zivot, Eric - 2008
accounts for time variation in macroeconomic volatility, known as the great moderation. In particular, we consider an … volatility processes and mixture distributions for the irregular components and the common cycle disturbances enable us to … that time-varying volatility is only present in the a selection of idiosyncratic components while the coefficients driving …

A dynamic multivariate heavy-tailed model for time-varying volatilities and correlations
Creal, Drew; Koopman, Siem Jan; Lucas, André - 2010
We propose a new class of observation-driven time-varying parameter models for dynamic volatilities and correlations to handle time series from heavy-tailed distributions. The model adopts generalized autoregressive score dynamics to obtain a time-varying covariance matrix of the multivariate...

Modeling dynamic volatilities and correlations under skewness and fat tails
Zhang, Xin; Creal, Drew; Koopman, Siem Jan; Lucas, André - 2011
We propose a new model for dynamic volatilities and correlations of skewed and heavy-tailed data. Our model endows the Generalized Hyperbolic distribution with time-varying parameters driven by the score of the observation density function. The key novelty in our approach is the fact that the...
