2023/04: Job competition in civil servant public examinations and sick leave behavior

In several countries the entry system to access public service positions is the traditional public examination procedure. In this setting, candidates have to take passing exams that require a huge load of material to study, and therefore time. Candidates who are working while preparing the public exam may find it difficult to devote enough time to both tasks. Thus, they might experience increased stress/anxiety related to high stakes civil service recruitment testing. In this paper, we investigate the impact of new openings of civil servant positions on sickness absences. Using a unique administrative dataset on the universe of sickness absences and civil servant positions offered in Spain from 2009 to 2015, we find a significant increase in health-related absences several months before the examination date. In particular, this effect is stronger for individuals working in the educational sector as well as for calls offering a large number of positions. This effect is mostly driven by stress related absences. Finally, using data on medical visits (GP and specialist) we find evidence consistent with a deterioration in public sector workers’ health. Our results are important from a policy perspective as they highlight the existence of important negative consequences of the civil service recruitment process that have been previously overlooked.

2023/03: Optimal tax administration responses to fake mobility and underreporting

In a two-country model, the citizens of a ‘big home country’ can either fictitiously move residence to a ‘small foreign country’ where residence-based taxes are lower (external tax avoidance), or under-report the tax base at home (internal tax avoidance). Tax setting is the result of Cournot-Nash competition between revenue maximizing governments, with the home government also setting two types of administration policies, one for each form of tax avoidance. We show that although it is optimal to employ both types of administration policies, which in themselves are both effective at tackling the targeted form of tax avoidance, the optimum is characterized by a tradeoff in terms of policy outcomes: either internal avoidance increases and external avoidance decreases, or the opposite, depending on the characteristics of the fiscal environment.

2023/02: Fiscal knowledge and its impact on revealed MWTP in Covid times: Evidence from survey data

Individual preferences over public policies should ideally be based on the possession of correct information about their reality. To test whether this holds, we conducted four waves of a survey, every six months since May 2020 (still under the COVID-19-lockdown), asking basic macro questions regarding the level of tax burden, of public debt, and of the underground economy in Spain. The percentage of correct responses (defined within broad ranges) never reaches 35%, and it is by far lowest for public debt. For the tax burden, left-wing individuals (with respect to right-wing) make more errors, and highly educated people (with respect to the rest of society) make fewer.

2023/01: Place-based policies: Opportunity for deprived schools or zone-and-shame effect?

Even though place-based policies involve large transfers toward low-income neighborhoods, they may also produce territorial stigmatization. This paper appeals to the quasi-experimental discontinuity in a French reform that redrew the zoning map of subsidized neighborhoods on the basis of a sharp poverty cut-off to assess the effect of place-based policies on school enrollment into lower secondary education. Using a difference-in-differences approach, we find strong evidence of stigma from policy designation, as public middle schools in neighbourhoods below the policy cut-off, which qualified for place-based subsidies, saw a significant 3.5pp post-reform drop in pupil enrollment, compared to their counterfactual analogues in unlabeled areas lying just above the poverty threshold. This “zone-and-shame” effect is immediate but does not persist, as it is only found for the first pupil-entry cohort in middle schools immediately after the reform. We show that it was triggered by the behavioral reactions of parents from all socioeconomic backgrounds, who avoided public schools in policy areas and shifted to those in other areas or, only for richer parents, to private schools. We uncover, on the contrary, only weak evidence of stigma reversion after an area loses its designation, suggesting hysteresis in bad reputations.

2022/10: Decomposing the impact of immigration on house prices

Immigrant inflows affect local house prices by increasing housing demand when housing supply is fixed. In this paper, I show that we can formally decompose total demand changes into changes stemming from an immediate increase in population due to new arrivals (“partial effect”) and additional changes in demand from relocated natives (“induced effect”). I propose a methodology to separately estimate these two effects using Spanish provinces’ data from 2001- 2012. Applying an instrumental variables approach, I find that a 1 p.p. increase in the immigration rate increases average house prices by 3.3% and rents by 1%. Partial demand estimates are 24% smaller than the total estimates, due to immigrants and natives locating in the same provinces. The results show that accounting for the impact of immigration on native location choices is key to understanding net demand adjustments, as partial and total effects can significantly differ depending on native population mobility.

2022/09: (IN)convenient stores? What do policies pushing stores to town centres actually do?

England´s Town Centre First Policy, introduced in 1996, restricted the opening of new retail and other ‘traditional town centre activities’ to ‘Town Centre’ (TC) locations. The aim was to halt the decay of high streets. We explore the impact of the policy on the supply and location of grocery shops and patterns of shopping by comparing English with Scottish TCs before and after the policy change in England. Using store level census data, we show first that supply trends for grocery stores in TCs were similar in both countries prior to the implementation of the policy. After the policy took effect, however, stores in TCs increased relatively more strongly in England, but with no change in grocery employment. Second, using survey data, we show that the policy changed the composition of shops in TCs in favour of convenience-type shops supplied by the “big four” grocery chains. However, although it increased the number of TC shops, the policy had no effect on the number of shoppers choosing TC locations.
