West Nile virus in Spain: Forecasting the geographical distribution of risky areas with an ecological niche modelling approach.
2021
West Nile virus (WNV), a well-known emerging vector-borne arbovirus with a zoonotic life cycle, represents a threat to both public and animal health. Transmitted by ornithophilic mosquitoes, its transmission is difficult to predict and even more difficult to prevent. The massive and unprecedented number of human cases and equid outbreaks in Spain during 2020 interpellates for new approaches. For the first time, we present an integrate analysis from a niche perspective to provide an insight to the situation of West Nile disease (WND) in Spain. Our modelling approach benefits from the combined use of global occurrence records of outbreaks of WND in equids and of its two alleged main vectors i…
The expression of virulence during double infections by different parasites with conflicting host exploitation and transmission strategies
2011
In many natural populations, hosts are found to be infected by more than one parasite species. When these parasites have different host exploitation strategies and transmission modes, a conflict among them may arise. Such a conflict may reduce the success of both parasites, but could work to the benefit of the host. For example, the less-virulent parasite may protect the host against the more-virulent competitor. We examine this conflict using the waterflea Daphnia magna and two of its sympatric parasites: the blood-infecting bacterium Pasteuria ramosa that transmits horizontally and the intracellular microsporidium Octosporea bayeri that can concurrently transmit horizontally and verticall…
Metropolitan wastewater analysis for COVID-19 epidemiological surveillance
2020
The COVID-19 disease, caused by severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), is a rapidly emerging pandemic which has enforced extreme containment measures worldwide. In the absence of a vaccine or efficient treatment, cost-effective epidemiological surveillance strategies are urgently needed. Here, we have used RT-qPCR for SARS-CoV-2 detection in a series of longitudinal metropolitan wastewaters samples collected from February to April 2020, during the earliest stages of the epidemic in the Region of Valencia, Spain. We were able to consistently detect SARS-CoV-2 RNA in samples taken in late February, when communicated cases in that region were only incipient. We also find…
Salud pública, espacio urbano y exclusión social en la España de posguerra: la epidemia de tifus exantemático en la ciudad de Valencia, 1941-1943
2019
Resumen Tras la Guerra Civil, las deficientes condiciones higiénico-dietéticas de gran parte de la población española favorecieron la aparición de enfermedades epidémicas. El tifus exantemático puso en jaque a las autoridades sanitarias, especialmente durante la primavera de 1941, cuando el ciclo epidemiológico de la enfermedad y la falta de infraestructuras se aliaron para provocar una grave crisis sanitaria. El régimen franquista, consciente de que esta situación dificultaba su legitimación, no dudó en utilizar la exclusión social como parte de su política sanitaria contra esta epidemia. El artículo analiza en profundidad el caso de Valencia, una ciudad que durante la guerra, por hallarse…
The euro area sovereign debt crisis: Can contagion spread from the periphery to the core?
2014
Abstract We examine the determinants of joint default risk of euro area countries during 2007–2011. To accomplish this, we recover joint default probabilities from individual CDS contracts. In contrast to earlier theoretical studies, we find that financial linkages are an active contagion transmission channel only in the case of the troubled periphery euro area economies. During the current sovereign debt crisis, real economy linkages play a more important role in transmitting shocks from the euro area periphery towards its core. Countries that have stronger trade interconnections with troubled economies tend to have a higher expected joint default risk.
Nonlinearity in intergenerational income transmission: A cross-country analysis
2016
Abstract The aim of this paper is to explore nonlinearity in intergenerational income transmission. We use a set of occupational tables in different countries to test nonlinearity. We also empirically address how policy variables can affect nonlinearity. Our findings suggest that concavity is supported in those societies with less credit constraints, but with more poverty and income inequality; education has an increasing effect on convexity.
Region vs. Industry Effects and Volatility Transmission
2006
This article presents an analysis of the relative importance of region versus industry effects in stock returns, as opposed to the extensively analyzed country versus industry effects. The sample includes the period after the bursting of the technology bubble. Moreover, volatility transmission patterns are analyzed within an industry across regions to assess whether the same international links found in aggregate stock market indices exist at the industry level. The results confirm the dominance of region effects over industry effects, except during the bubble period. The results of the volatility transmission analysis suggest that the importance of spillovers depends on the industry.
Job protection deregulation in good and bad times
2019
Abstract This paper explores the short-term employment effect of deregulating job protection for regular workers and how it varies with prevailing business cycle conditions. We apply the local projection method to a newly constructed dataset of major regular job protection reforms covering 26 advanced economies over the past four decades. The analysis relies on country-sector-level data, using as identifying assumption the fact that stringent dismissal regulations are more binding in sectors that are characterized by a higher ‘natural’ propensity to make regular adjustments to the workforce. We find that the response of sectoral employment to deregulation depends crucially on the state of t…
Employment protection : its effects on different skill groups and on the incentive to become skilled
2005
Summary Employment protection affects labour market outcomes and hence the incentive to acquire skills. Using a matching model with two education levels in which workers decide ex-ante on their skill formation, it is shown that employment protection can raise the fraction of skilled workers. This will be the case if workers obtain a sufficiently large fraction of the rent created by skill formation. Furthermore, it will be shown that high-skilled workers face shorter unemployment duration and lower dismissal probabilities.
Globalization of Monitoring Practices: The Case of American Influences on the Dismissal Risk of European CEOs
2013
Accepted version of an article from the Journal of Economics and Business This study examines globalization of monitoring practices by focusing on how American (U.S.) influences on European firms impact the dismissal risk for these firms' CEOs. Specifically, we argue that the stronger short term orientation of the American corporate governance system increase the dismissal performance sensitivity faced by European CEOs, indirectly and directly. The former materializes via European firms cross-listing on U.S. exchanges, the latter results from European firms hiring U.S. independent board members. Both influences are expected to result in increased dismissal performance sensitivity. Based on …
