The average worker in the US needs to work more than a year to earn his or her CEO's daily wage. The well-accepted justification among economists for these huge wage gaps is the necessity to achieve economic efficiency, in terms of efficient allocation in the labor market and incentivizing...

This article uses cross-country data to explore the role of cultural attributes in the inequality of income distribution and poverty within countries. Using the Hofstede cultural dimensions, we found that individualism is negatively correlated with the Gini index and the poverty ratio. We also...

In this paper we analytically study the effect of social hubs on the penetration of new products. Aggregating individual-level social network considerations to the market level, we identify boundary conditions for hubs' effect on diffusion. Our results demonstrate that seeding hubs has a...

Advertisements that present the image of the slim figures of models, movie actors and celebs are often blamed in triggering anorexia. In this paper we suggest that the slim model effect on consumers' weight is substantially greater than previously estimated due to its role in the emergence of...

Online communities exist in many forms and sizes. Yet, there is limited insight into why some online communities are sustainable, while others disappear. We find that in order to maintain sustainability, online communities exhibit a typical hierarchical social circle structure that balances...

We show how networks modify the diffusion curve by affecting its symmetry. We demonstrate that a network's degree distribution has significant impact on the contagion properties of the subsequent adoption process, and propose a method for uncovering the degree distribution of the adopter network...

The aim of this research is to explore the effect of a lower return on education in peripheral regions of a country compared to core regions on the decision of individuals in each region to acquire human capital by advancing their education. In addition, the study examines how these decisions...

In this research we show that workers aged 30-44 were significantly more likely than those aged 45-59 to find a job a year after being unemployed. The main contribution is demonstrating empirically that since older workers' difficulties are related to their age, while for younger individuals the...

Identifying the impact of tax structures on economy growth is crucial to those who create tax policies. In this paper we create a tool called the Tax Structure Efficiency Index that is based on the level of the concentration of the tax system for assessing the efficiency of the tax structure. We...
