Dynamics of HPV vaccination initiation in Flanders (Belgium) 2007-2009: a Cox regression model

<p>Abstract</p> <p>Background</p> <p>We investigated dynamic patterns and predictors of HPV vaccination initiation in Flanders (Belgium) by girls aged 12 to 18, between 2007 and 2009, the period immediately after the introduction of the HPV vaccines on the Belgian market. During this period the initiative for vaccination was taken by the girl, her family or the general practitioner/pediatrician/gynecologist.</p> <p>Methods</p> <p>We used a Cox regression model with time constant and time varying predictors to model hazard rates of HPV vaccination initiation. The sample existed of 117,151 female members of the National Alliance of Christian Mutualities, the largest sickness fund in Flanders.</p> <p>Results</p> <p>The study showed that the hazard of HPV vaccination initiation was higher (1) for older girls, (2) for girls with a more favorable socio-economic background, (3) under more generous reimbursement regimes (with this effect being more pronounced for girls with weak socioeconomic backgrounds), (4) for girls that were informed personally about the reimbursement rules.</p> <p>Conclusions</p> <p>When the initiative for HPV vaccination lies with the girls, their families or the physicians (no organized setting) the uptake of the vaccines is affected by both individual and organizational factors.</p

Bank location and financial liberalization reforms: evidence from microgeographic data

We examine the effects of bank deregulation on the spatial dynamics of retail-bank branching, exploiting, much like a quasi-natural experiment, the context of intense liberalization reforms in Belgium in the late nineties. Using .ne-grained data on branch network dynamics within the metropolitan area of Antwerp and advancing novel spatial econometric techniques, we show that these liberalization reforms radically shifted and accelerated branch network dynamics. Entry and exit dynamics substantially intensified, the level change in financial void grew significantly, and bank choice markedly declined. Moreover, all these changes consistently extended (even with greater intensity) after the liberalization peak. However, the immediate and longer-term spatial ramifications of the financial sector liberalization were very distinct. All immediate changes systematically, differentially impacted the poorer and wealthier neighborhoods, disenfranchising the poorer neighbourhoods and favoring their wealthier counterparts. The longer-term effects on spatial patterns of change no longer exhibited this systematic relationship with neighborhood income. We draw out the policy implications of our finding

Child Benefit Support and Method of Payment: Evidence from a Randomized Experiment in Belgium

We examine the effects of information and information presentation format on individuals' choice of payment method in a large randomized experiment carried out with the Belgian National Office for Family Benefits. We find that a one-time mailing providing information about method of payment for child benefit support caused a fourfold increase in parents' decision to switch from payment by check to electronic payment. Simple, low-cost supplements significantly raised people's responsiveness to the mailing. Our results suggest that complexity and information (processing) costs pose significant barriers to transitioning to electronic payment methods, and that deliberate efforts to lower these costs can contribute to large behavioral changes.

Dynamics of retail-bank branching in Antwerp (Belgium) 1991–2006: evidence from micro-geographic data

We exploit a comprehensive new panel dataset on retailbank branch locations in 233 neighborhoods (local markets) in the metropolitan area of Antwerp to describe (i) how between 1991 and 2006 the patterns of bank presence, entry, exit and choice deeply evolve and (ii) whether and how changes in these "on the ground" patterns systematically diverge across Antwerp's different, highly segregated neighborhoods. We show that over the 15-year period under study entry and exit dynamics substantially intensify, the level change in branch desert grows significantly, and bank choice markedly declines; and that between 1996 and 2001, these changes are robustly associated with the neighborhood average income. In doing so, we advance a new technique for generating spatial measures that both minimize the discretization bias and can be reliably linked to neighborhoods. We demonstrate that the resulting measures are indeed more precise than traditional count measures
