“…Multi-band photometry for a huge number (∼23000) of southern field RRLs has also been released by CATALINA (Drake et al 2013;Torrealba et al 2014). Similar findings have been provided in the NIR bands by VVV for RRLs in the Galactic bulge (Minniti et al 2014) and by VMC (Moretti et al 2015, in preparation) for RRL in the MCs. New optical catalogs have also been released by large optical surveys such as SDSS and Pan-STARRS1 (Abbas et al 2014) and UV surveys such as GALEX (Gezari et al 2013;Kinman & Brown 2014).…”

We present new nonlinear, time-dependent convective hydrodynamical models of RR Lyrae stars computed assuming a constant helium-to-metal enrichment ratio and a broad range in metal abundances (Z = 0.0001-0.02). The stellar masses and luminosities adopted to construct the pulsation models were fixed according to detailed central He burning Horizontal Branch evolutionary models. The pulsation models cover a broad range in stellar luminosity and effective temperatures and the modal stability is investigated for both fundamental and first overtones. We predict the topology of the instability strip as a function of the metal content and new analytical relations for the edges of the instability strip in the observational plane. Moreover, a new analytical relation to constrain the pulsation mass of double pulsators as a function of the period ratio and the metal content is provided. We derive new Period-Radius-Metallicity relations for fundamental and first-overtone pulsators. They agree quite well with similar empirical and theoretical relations in the literature. From the predicted bolometric light curves, transformed into optical (U BVRI) and near-infrared (JHK) bands, we compute the intensity-averaged mean magnitudes along the entire pulsation cycle and, in turn, new and homogenous metaldependent (RI JHK) Period-Luminosity relations. Moreover, we compute new dual and triple band optical, optical-NIR and NIR Period-Wesenheit-Metallicity relations. Interestingly, we find that the optical Period-W(V, B − V) is independent of the metal content and that the accuracy of individual distances is a balance between the adopted diagnostics and the precision of photometric and spectroscopic datasets.

“…The seminal studies in this literature are Romer (1990), Segerstrom et al (1990), Grossman and Helpman (1991) and Aghion and Howitt (1992). Subsequent studies in this literature apply variants of the R&D-based growth model to explore the e¤ects of patent protection and R&D subsidies on innovation and economic growth; 3 see for example Peretto (1998) Minniti and Venturini (2014) and Kiedaisch (2015). These studies focus on a representative-household framework and do not consider the distributional implications of patent protection and R&D subsidies.…”

This study explores the e¤ects of patent protection and R&D subsidies on economic growth and income inequality using a Schumpeterian growth model with heterogeneous households. We …nd that although strengthening patent protection and raising R&D subsidies have the same macroeconomic e¤ect of stimulating economic growth, they have drastically di¤erent microeconomic implications on income inequality. Speci…cally, strengthening patent protection increases income inequality whereas raising R&D subsidies decreases (increases) it if the quality step size is su¢ ciently small (large). An empirically realistic quality step size is smaller than the threshold, implying a negative e¤ect of R&D subsidies on income inequality. We also calibrate the model to provide a quantitative analysis and …nd that strengthening patent protection causes a moderate increase in income inequality and a negligible increase in consumption inequality whereas raising R&D subsidies causes a relatively large decrease in both income inequality and consumption inequality.JEL classi…cation: D30, O30, O40

“…Conclusions indicating a long-run effect of tax incentives on R&D activities were drawn by Minniti and Venturini (2013) based on an analysis of nineteen industries in the U.S. between 1975 and 2000. Their study indicated that subsidies on research activity increase the R&D efforts and economic growth rates, but only temporarily.…”

Purpose:The article aimed to determine the general relationships between economic growth and development and selected innovativeness indicators in two countries belonging to the leaders of innovativeness in comparison with two countries of Central and Eastern Europe representing moderate innovators. Design/Methodology/Approach: Cluster analysis (agglomeration method), elements of descriptive statistics, correlation calculus, and the ADF test were used to study the stationarity of the variables initially. Findings: The results have shown that the analyzed innovativeness indicators have fluctuated to varying degrees, although in many cases, Poland and Hungary demonstrated high rates of growth, which could suggest a catching-up effect. Although the correlation coefficients between the levels of economic growth and development and the analyzed innovativeness variables were in many cases significant (usually positive), stationarity tests showed that the variables are in the vast majority non-stationary, which is a reason for further research when trying to build an econometric model. Practical Implications: A general analysis of the data indicated that the following stages of the study would require an expansion to include a cointegration account and determine the interrelationship of variables in both the short and long term, using autoregressive models. Originality/Value: Preliminary analysis of economic growth factors using descriptive statistics and correlation coefficients for selected countries (Sweden, the Netherlands, Poland, Hungary) based on available source data from OECD.
