During the last decade, several studies have argued that sticky information model proposed by Mankiw and Reis (2002), in which firms update their information occasionally rather than instantaneously, explains some stylized facts about the inflation dynamics. Sticky information pricing model successfully captures the sluggish movement of aggregate prices in response to monetary policy shocks. Despite the importance of sticky information, no empirical studies have been done yet to estimate sticky information Philips Curve (SIPC) and its key parameter - the degree of information rigidity - in Iran. This paper is the first attempt to estimate the degree of information stickiness in Iran using the two stage empirical approach proposed by Khan and Zhu (2006). Having the correct structural parameter allows a better understanding of the dynamics of inflation. Results show that the average duration of information stickiness ranges from 3.2 to 4 quarters in Iran. In addition, the existence of threshold effects in SIPC is also tested in this paper. Based on the estimation of TAR model over 2002Q2- 2015Q1, firms update information faster when inflation is higher. This evidence suggests that firms are more aware of macroeconomic conditions when inflation is higher; that is, missing information during high inflation periods is costly.

With the growth of capital market, the shareholding structure of companies has become more complex. Direct ownership is easily recognizable through companies’ shareholders information, however with the formation of cross shareholding among companies, a kind of indirect and complex shareholding has emerged which is not observable. The primary owners (original owners) can take over other companies through intermediate owners. In this research a model is presented to identify and investigate the structure of indirect ownership. Identifying the hidden ownership relations together with determining the level of complexity of network and the degree of ownership concentration are among the capabilities of this model. To this end, the ownership network of Tehran Stock Exchange in June 2014 was analyzed. The results indicate that over 86 percent of all observed ownership relations have been formed by indirect ownership and at least with the presence of one intermediate owner. Moreover, 15.35 percent of the market’s total value (equals with 547 thousands billion Rials) was calculated twice and also studying the degree of concentration of ownership indicates that over 60 percent of the market’s total value belongs to only 10 percent of the shareholders.

In this paper we construct a modeling for detection of banks which are experiencing serious problems. Sample and variable set of the study contains 30 banks of Iran during 2006-2014 and their financial ratios. Well known multivariate statistical technique (principal component analysis) was used to explore the basic financial characteristics of the banks, and discriminant Logit and Probit models were estimated based on these characteristics. Results suggest that the model can be used as an analytical decision support tool in both on-site and off-site bank monitoring system to detect the banks which are experiencing serious problems.

In the classical Greek thought, the notion of “right” was concomitant with the “truth”. In the modern era, however, the notion of “right” became intertwined with the primacy of   “possessive individuality”. This primacy was, however, from the outset intellectually challenged. In the light of challenges posed, and by invoking the commonalities between Shahaboddin Suhrawardi and Martin Heidegger, the right to excellence is envisioned here as a maximal theory of “human rights”.
