Monetary policy rule is an approach to avoid time inconsistency problem as regarded by new classical economist to choose a time plan for policy making in order to maximize households€™ well-being. The foundation of time inconsistency problem is not coincidence of expectations as an ex-ante variable, which is expected variable, with actual variable as an ex-post variable. Expectations in Finn Kydland and Edward Prescott as the 2004 laureates of the Nobel Memorial Prize in Economics, is rational and formed only by a representative agent because of the discretionary policy of benevolent planner. However the benevolent planner may be as an international planner. In this paper, we develop the model of Kydland and Prescott, by substituting the assumption of heterogeneous households (a domestic household and foreign household) instead of a representative agent and using heterogeneous beliefs. The recent assumption helps us to have an alternative time inconsistency equilibrium with at least two different sources of expectations, which is called Dichotomy Sources of Expectations (DSE) as the main contribution of this paper .We then use expectations-adjusted Phillips curve to see the conditions of time inconsistency of k percent monetary rule of Friedman in a framework of DSE €™s Model . The results show that expectations-adjusted Phillips curve in a society with DSE is not vertical and Friedman's k-percent rule may not be optimal. We find out that, not only an international benevolent planner but also a foreign household must set a rule to maximize the well-being of the world. Indeed, we need a multi-dimensional rule for any international monetary policy.   JEL Classification: D83, D81, D84, E52, E63

  This paper examines impact of trade liberalization on industrial growth of India. The research problem is expressed as €œTo what extent does trade liberalization or openness of the economy influence industrial growth of India?€ To identify the impacts of trade liberalization, total time period, 1970-2010, is divided into two sub periods of before trade liberalization i.e. (1970 to 1990) and after trade liberalization i.e. (1991 to 2010). The variables identified in the main objective of the study are tested hypothetically, and quantitative analytical methods are applied to make accurate and reliable conclusions. Graphical presentations and regression analyses are used to assess the degree of relationships among variables concerned. Further to test the structural changes in the country, the Chow test is applied. Findings of the study confirm that there is no evidence that the structural changes in industrial growth rates have been happened during the last four decades due to trade liberalization in India.

The Realization Optimality Theory is a recent development in the original Optimality Theory which is proposed to deal with morphological issues especially the inflectional ones. Its main idea is to consider the morphological realization rules as ranked violable language-specific constraints that control the realization processes and provide phonological information of grammatical morphemes. This article deals with the investigation of some morphosyntactic (inflectional) features of modern Persian in Realization Optimality Theory, and shows among the other things that it is a better model for treating inflection than the original Optimality Theory, but it still faces some problems with regard to a language like Modern Persian in which some morphosyntactic features are treated differently in formal and informal varieties, hence separate tableaux with different rankings of constraints are sometimes needed in order to select the optimal candidates in each of those varieties.
