Empirical results through a fixed effects regression model show that government size has a negative effect on growth mainly through hampering capital accumulation. When a sample is divided into OECD and non-OECD countries, the negative effect of government size on capital accumulation persists for non-OECD countries but not for OECD countries.
Does online availability boost citations? Using a panel of citations to economics and business journals, we show that the enormous effects found in previous studies were an artifact of their failure to control for article quality, disappearing once fixed effects are added as controls. The absence of aggregate effects masks heterogeneity across platforms: JSTOR has a uniquely large effect, boost...
Using panel data for 24 (OECD) countries during the period 1980–2004 this study examines how social trust affects fertility. The major finding through the random effects approach is that the social trust increases the fertility rate. A 1% rise in the trust rate leads to an increase in fertility by 0.01 points. The results presented here suggest that in developed countries, trust underlies the d...
Various authors find that in OECD countries the cross-country correlation between the total fertility rate and the female labour force participation rate turned from a negative value before the 1980s to a positive value thereafter. Based on pooled time series analysis the literature seems to agree that this change is due to unmeasured country and time heterogeneity with respect to female employ...
Improvements in product design are conventionally made after the start of massproduction, followed by reductions in cost and lead-time. However, in light of the shorter product life-cycles and high-mix/low-volume production of recent years, it is increasingly important to carefully optimize productivity from the initial stages of massproduction. It is generally considered that design determines...
Introduction: Fatty liver is a condition in people with type 2 diabetes mellitus (T2DM). The purpose of this study is to examine the effects of combined training on novel hepatic steatosis indices (fatty liver index (FLI), accumulation product (LAP), hepatic steatosis index (HSI), and Framingham steatosis index (FSI)) in women with type 2 diabetes. Methods: 35 female with type 2 diabetes wer...
This article tests the subset of public choice models for social security that have empirical implications. The data, collected from OECD countries for the years 1960, 1970, 1980, and 1990, provide some support for each of the theories. Higher median voter age, more income heterogeneity, greater similarity in family size, and variables that make a public pension program more profitable are all ...
Why has physical piracy of music grown globally in recent years despite international efforts to reduce the problem? This research employs cross-country time series data analysis to examine physical music piracy rates across developed and developing economies. We provide 1999-2004 cross-country evidence from 70 countries that mean global music piracy rates grew over this period, and observe dif...
This study aimed at the efficacy of "Neurofeedback", "Compared to Ritalin" and "Combined Neurofeedback and Ritalin" for managing and controlling ADHD symptoms through an experimental design. Sixteen students with ADHD (combined type) were assigned to three different therapeutic settings("Neurofeedback", "Ritalin", and "Combined Neurofeedback and Ritalin") and one Waiting-List setting. All parti...
اثربخشی آتشسوزی تجویزشده، کنترل مکانیکی و شیمیایی بر مدیریت ورک (Rosa persica) در مراتع تخریبشده
Invasive plant control is a significant challenge for natural resources management. Rosa persica (Michx ex. Juss.) is one of the invasive species in Iran. It has been rapidly expanded to the areas where it has introduced. In the present study, we evaluated the effects of five treatments: 1) control, 2) fire, 3) cutting, 3) tilling, 4) chemical techniques (glyphsate application) in controlling ...
