Pairwise stability (Jackson and Wolinsky, 1996) is the standard stability concept in network formation. It assumes myopic behavior of the agents in the sense that they do not forecast how others might react to their actions. Assuming that agents are farsighted, related stability concepts have been proposed. We design a simple network formation experiment to test these theories. Our results prov...

abstract research and development (r&d;) spending plays a major role in innovation, raising productivity and increasing economic growth. the purpose of this paper is to investigate the impact of r&d; spending on growth and total factor productivity (tfp) in iran's agricultural sector. we estimate growth and productivity models using auto-regressive distributed lag (ardl) approach and data over ...

We examine a variety of stability and equilibrium de…nitions that have been used to study the formation of social networks among a group of players. In particular we compare variations on three types of de…nitions: those based on a pairwise stability notion, those based on the Nash equilibria of a link formation game, and those based on equilibria of a link formation game where transfers are po...

We study a resource constrained assembly line balancing problem (RCALBP) presented by Ağpak and Gökçen, who developed a 0-1 integer programming model to find the optimal solution. However, this model is inefficient in solving large-scale problems. In this paper, we propose a simple efficient heuristic that is based on the widely-used ranked positional weight (RPW) rule. The example given by Ağp...

t his paper investigates the asymmetric behavior of inflation. we use logistic smooth transition autoregressive (lstar) model to characterize the regime-switching behavior of iran’s monthly inflation during the period may 1990 to december 2013. we find that there is a triple relationship between the inflation level, its fluctuations and persistence. the findings imply that the behavior of infla...

abstract i n this paper, we investigate the existence and the nature of real exchange rate misalignment in organization of the petroleum exporting countries (opec). to do this we estimated a cross country basic real exchange rate determination model for 1990-2012 and extracted historic trend of misalignment. the results imply that all opec countries have had misalignment -of different kinds tho...

network effects, increase in the value of consuming a product if many other consumers use the same product, is a feature of many markets of high-technology products. frequently cited examples of products exhibiting network effects are telecommunication or software products. this research explores the role of network effects in the consumer´s choice of mobile operator in tehran. for our empirica...

We develop a model where workers, anticipating the possibility of unemployment, invest in connections to access information about available jobs. The investment in connections is high when the job separation rate is moderate, otherwise the investment in connections is low. The response of network investment to labor market conditions generates novel predictions. In particular, the probability t...

Many social and economic networks emerge among actors that only partially observe the network when forming network ties. We ask: what types of network architectures form when actors have limited observation, and does limited observation lead to less effi cient structures? We report numerous results from a laboratory experiment that varies both network observation and the cost of forming links. ...
