Does Family Composition Affect Social Networking?
This paper analyzes the effect of family composition, and in particular the number of children, the age gap between the oldest and youngest child and the age of the youngest child, on parents' involvement in social networks. The predictions of a simple theoretical model are confirmed by an empirical analysis of Israeli Social Survey data for 2002-2006. The number of children has a U -shaped effect on parents' involvement in social networks, with substantial differences between fathers and mothers. The negative effect is dominant on the mothers' involvement in social networks, while the positive effect is dominant on the father's involvement in social networks. The age gap between children has a positive effect on both parents' involvement in social networks, while the age of the youngest child has a positive effect on the father's involvement in social networks. These results imply that social network considerations might be important for fertility decisions.social networks, family composition, children
Who Will Be Idol? The Importance of Social Networks for Winning on Reality Shows
This paper examines, both theoretically and empirically, the effect of social networks and belonging to minority groups (or race) on the probability of winning in reality television shows. We develop a theoretical model that studies viewer behavior by presenting a framework of competition between two contestants from two different groups. The results are examined empirically using unique contestant data from the highly popular reality show "A Star Is Born", the Israeli counterpart of "American Idol". Our main finding is that social networks and belonging to minority groups play key roles in the contestant’s victory, but their effects are nonlinear: the social network effect is U-shaped, whereas that of belonging to a minority group follows an inverted U shape. Beyond the world of reality TV, this paper sheds light on the general behavior of social networks as well.American Idol, social networks, minority groups, contest, voting
Illegal Migration, Enforcement and Minimum Wage
This paper examines the connection between illegal migration, minimum wages and enforcement policy. We first explore the employers' decision regarding the employment of illegal migrants in the presence of an effective minimum wage. We show that the employers' decision depends on the wage gap between those of the legal and illegal workers and on the penalty for employing illegal workers. We consider the effects a change in the minimum wage has on the employment of illegal immigrants and local workers. We conclude by considering the optimal migration policy taking into consideration social welfare issues.illegal immigration, migration policy, minimum wage, interest groups
Network Formations among Immigrants and Natives
In this paper we examine possible network formations among immigrants and natives with endogenous investment. We consider a model of a network formation where the initiator of the link bears its cost while both agents benefit from it. We present the model by considering possible interactions between immigrants and the new society in the host country: assimilation, separation, integration and marginalization. The paper highlights different aspects of immigrants’ behavior and their interaction with the members of the host country (society) and their source country (society). We found that when the stock of the immigrants in the host country increases, the immigrants' investment in the middlemen increases and the natives may bear the cost of link formation with the middlemen.assimilation and separation, social networks, network formations
Does Family Composition Affect Social Networking?
This paper analyzes the effect of family composition, and in particular the number of
children, the age gap between the oldest and youngest child and the age of the youngest
child, on parents’ involvement in social networks. The predictions of a simple theoretical
model are confirmed by an empirical analysis of Israeli Social Survey data for 2002-
2006. The number of children has a U -shaped effect on parents' involvement in social
networks, with substantial differences between fathers and mothers. The negative effect
is dominant on the mothers’ involvement in social networks, while the positive effect is
dominant on the father's involvement in social networks. The age gap between children
has a positive effect on both parents’ involvement in social networks, while the age of the
youngest child has a positive effect on the father's involvement in social networks. These
results imply that social network considerations might be important for fertility decisions
The Formation of Immigrant Networks in the Short and the Long Run
In this paper, we present a formal framework of possible network formations among immigrants. After arriving in the new country, one of the new immigrant’s important decisions is with whom to maintain a link in the foreign country. We find that the behavior of the first two immigrants affects all those who come after them. We also find that in the long run, under specific conditions, the first immigrant will become the leader of the immigrant society. Over time, as the stock of immigrants in the host country increases, the investment in the link with the leader will increase as well
Sociability and the timing of first marriage
This paper investigates, both theoretically and empirically, the effect of sociability on the age of marriage. Theoretically, a more sociable individual has higher chances of finding a suitable partner for marriage early in life, and hence is expected to marry earlier than an otherwise similar unsociable individual. On the other hand, a more sociable individual can afford to be more selective in choosing a mate and therefore will tend to postpone marriage until the most suitable partner is found. Using a survival model applied to Israeli data, we show that the first effect is dominant for relatively less sociable individuals, whereas the second effect is dominant for relatively more sociable individuals. Hence, people with intermediate levels of sociability will tend to marry earlier. In an era of increasing individualism and decreasing sociability, these results have important implications for marriage rates, fertility, housing markets and financial markets
