Alcohol demand among young people in Spain: an addictive QUAIDS

This paper analyzes the demand for alcoholic beverages among young people in Spain. To that end, we develop a theoretical model which combines elements from the Theory of Two-Stage Budgeting and the Theory of Addiction, with this being empirically translated into a Quadratic Almost Ideal Demand System (QUAIDS) in which the particular characteristics of young people are introduced by Price Scaling (PS) techniques. We then estimate this specification by using data drawn from the Spanish National Survey on Drug Use in the School Population (2000) and the Spanish National Household Survey (2000). Given that wine, beer and spirits all have normal demands, our results suggest that a tax increase imposed with the intention of reducing alcohol consumption would appear to be efficient.

An application of padé approximation to volatility modeling

This paper studies the dynamic relationship between future volatility and implied and historical volatility using data from Alegría and Rodríguez [1997]. The methodological approach forms part of the theoretical research being carried out in numerical analysis and especially from the rational Padé approximation. This tool helps to characterize simple computational methods in order to study questions about dynamic modelization of doubly infinite series. Considering noncausal series, where the expectations provided by economic theory or empirical evidence are included in available sample data, leads to dynamic specifications suitable not only from the perspective of fitting available data, but also from their predictive performance when compared to traditionally used formulae based merely on data analysis.     

Testing PPP for the South African Rand/US Dollar Real Exchange Rate at Different Data Frequencies

This paper tests the PPP hypothesis for the South African rand/US dollar real exchange rate using a fractional integration framework. The results suggest that the real exchange rate of the South African rand with respect to the US dollar is a highly dependent variable with an order of integration very close to 1. This finding is not affected by the data frequency considered (daily, weekly or monthly). Also, there appears to be a single break in December 2001 (possibly corresponding to a change in the monetary policy framework), with the unit root null being rejected in favour of d > 1 for the periods before the break, but not afterwards. Thus, our results strongly reject the PPP hypothesis for the South African rand/US dollar rate across data frequencies, since shocks are found to affect the exchange rate forever.     

Single european currency: Effects on firm structure and personnel management

This paper examines the likely effects of the introduction of the single European currency, whose arrival means that the development of the economic space of the European Union will be completed. Two aspects of the forthcoming changes are analyzed. First is the process of monetary integration, which will spread over three years, and is here reviewed chronologically. Second is the final effect of this process on firms—how different company structures will adapt and what actions will have to be taken with regard to the management of human resources.

Lobbying contests with alternative instruments

This is a model of a contest where, in order to win, each opponent can use two instruments. The probabilities of winning are explored, as well as the expenditures of the interest groups, and the relative rent-dissipation in both cases where the players have the option to use only one instrument (the standard Tullock contest) and where the players have the option to use two instruments in the contest. We show that the use of two instruments strengthens the player with the higher stake, decreases the relative rent dissipation and it decreases total expenditure if the parties are sufficiently asymmetric.

The use of Zostavax in Spain: the economic case for vaccination of individuals aged 50 years and older

Background Population aging brings up a number of health issues, one of which is an increased incidence of herpes zoster (HZ) and its complication, post-herpetic neuralgia (PHN). Zostavax vaccine has recently become available to prevent HZ and PHN. This study evaluates the cost-effectiveness of vaccination against HZ in Spain considering a vaccination of the population aged 50 years and older and comparing this to the current situation where no vaccination is being administered.

Methods An existing, validated, and published economic model was adapted to Spain using relevant local input parameters and costs from 2013.

Results Vaccinating 30% of the Spanish population aged 50 years and older resulted in €16,577/QALY gained, €2025/HZ case avoided, and €5594/PHN case avoided under the third-party payer perspective. From a societal perspective, the ICERs increased by 6%, due to the higher price of the vaccine. The number needed to vaccinate to prevent one case was 20 for HZ, and 63 for PHN3. Sensitivity analyses showed that the model was most sensitive to the HZ and PHN epidemiological data, the health state utilities values, and vaccine price used.

Conclusion Considering an acceptable range of cost-effectiveness of €30,000–€50,000 per QALY gained, vaccination of the 50+ population in Spain against HZ with a new vaccine, Zostavax, is cost-effective and makes good use of the valuable healthcare budget.     

Inflation convergence in Central and Eastern Europe vs. the Eurozone: Non‐linearities and long memory

In this paper, we consider inflation rate differentials between seven Central and Eastern European Countries (CEECs) and the Eurozone. We test for convergence in the inflation rate differentials, incorporating non‐linearities in the autoregressive parameters, fractional integration with endogenous structural changes, and also consider club convergence analysis for the CEECs over the period 1997 to 2015 based on monthly data. Our empirical findings suggest that the majority of countries experience non‐linearities in the inflation rate differential; however, there is only evidence of a persistent difference in some countries. Complementary to this analysis we apply the Phillips and Sul (2007) test for club convergence and find that there is evidence that most of the CEECs converge to a common steady state.     

Assessing the Enlargement and Deepening of the European Union

This paper estimates a theoretically‐motivated gravity model to examine the effect of the European Union (EU) on trade and whether the order of entry has affected the trade performance of member countries. Additionally, we analyse the impact of the different phases of EU integration on trade. The results show that both original countries and successive enlargements boost intra‐bloc trade. Moreover, the results suggest that the deepening in the integration process has led to more trade creation among members. Finally, only the latter phase of the European integration process (the single currency) has increased trade with non‐members.
