The purpose of this paper is to investigate the effect of firm CREDIT CONSTRAINT on unemployment in a dynamic stochastic general equilibrium model within the 1996-2017 period. In this study, the financial friction occurs through the existence of incomplete contracts in the market. In this model, the limitation of borrowing for the firm is in relation to the stock of capital, which leads to a very slow response of the labor market to productivity momentum. A characteristic of this pattern is that, in every period, employment (or unemployment) comes from the conditions that prevail the labor market. In each period, the number of people recruited depends on job opportunities created by businesses and the number of the unemployed. In this case, if the number of job opportunities is low or the number of the unemployment is high, voluntary unemployment emerges, which is more compatible with the Iranian economy. The results show that the CREDIT impulse caused by the firm's limitation in the financing of investment in the country increases unemployment. The results also indicate that the limitation of firm CREDIT in the borrowing process leads to a decrease in job capacities and the probability of finding jobs in the market.

his paper investigates the effect of monetary policy on the distribution of economic activity and agglomeration economies within a country. The considered channel for this effectiveness is the availability of CREDIT to firms in various regions and the effects on the labor and consumer welfare. For this purpose, data for manufacturing firms located in 30 different provinces in Iran during 2007 and 2014 gathered. The empirical results from spatial panel data show that beside conventional channel of effectiveness through consumer and labor force utility function, regional monetary policy implication through uneven distribution of regional loanable banking fund seems to be substantial centripetal force. In terms of most well-known NEG variable, uneven regional accessibility of CREDIT market has opposite regional implication as trade freeness. While the former leads to more concentration of economic activity across space, the latter tends to drive dispersion. It is assumable that monetary policy reduce the impact of CREDIT CONSTRAINTs on firms but the degree of CREDIT availability in regions is a significant driver for concentration of economic activity. The result shows the importance of accessibility to banking loans on distribution of economic activities within the country.

In this paper an uncertain multi objective closed-loop supply chain is developed. The first objective function is maximizing the total profit. The second objective function is minimizing the use of row materials. In the other word, the second objective function is maximizing the amount of remanufacturing and recycling. Genetic algorithm is used for optimization; and for finding the pareto optimal line, Epsilon-CONSTRAINT method is used. Finally a numerical example is solved with proposed approach and performance of the model is evaluated in different sizes. The results show that this approach is effective and useful for managerial decisions.

This study investigates the presence of financial CONSTRAINT and its possible effect on the level of rice production in Gilan and Mazandaran provinces. To this end, an Indirect Production Function was estimated using 2007 crop year production data. Results support the claim that shortage of financial resources is a limiting factor in all cities in these two provinces such that the available financial resources in Gilan and Mazandaran is 23.01 percent and 21.04 percent, respectively, less than the amount required to finance optimum level of production. This limitation has resulted in a 24.78 percent and 23.22 percent decline in production, respectively in Gilan and Mazandaran, as compared to a non-CONSTRAINT situation. Given the share of these two provinces in providing the rice product needed in the country, supplying sufficient level of financial resources can play a considerable role in reducing import of this product.

Constrain is the condition of driven by necessity. The principle of CONSTRAINT determines the duties of the person constrained. In jurisprudence, it includes a range of activities from cleanness to blood compensation. However, jurisprudents have discussed it mainly with regard to those that can be eaten and drunk, and presented three different interpretations: fear of losing one"s life; fear in general, including fear of losing one"s life, or one"s limb, etc.; and fear of things not related to oneself but to others. The roots of CONSTRAINT are compulsion, precautionary concealment, loss and necessity. The present article deals with a kind of CONSTRAINT whose source is necessiy. The Qur"an has explicitly excused the person constrained from duties provided that the oppressor shows no inclination to sin. Tradition says that "there is so unlawful act that God Almighty has not made it permissible under CONSTRAINT." The intellect also knows it permissible to give up necessary duties and to do the unlawful acts under CONSTRAINT. Finally, the writer presents the conditions under which the application of the principle of constrain is made permissible.

The concept of design is associated with the notion of CONSTRAINT as a limiting factor, and the search for the CONSTRAINT in the design process is essential in design research. This study applies the ontological method to define the domain and scope of CONSTRAINTs, their classes and subclasses, and how to apply them. We concluded that there are two types of CONSTRAINTs in design: inside the designer’, s mind or internal CONSTRAINT and outside it or external CONSTRAINT. Each of these is classified into two subclasses: internal CONSTRAINTs can be divided into deduced and subject CONSTRAINTs, and external CONSTRAINTs are categorised into imposed and intrinsic CONSTRAINTs. In the end, we proposed a model that shows that designers can identify, choose, manage, and even generate CONSTRAINTs in the design process to facilitate the restructuring of the design problem, which helps them solve the design problem.

This study aims to describe and explain the metanarrative of the fundamental idea and concept of authority in traditional societies, art, and architecture. There is much evidence that the formation of art and architecture, the socio-professional organisation of craftsmen, class structure, and behaviours of the traditional societies was based on a hierarchical pyramid system of patterns or spiritual and material references. Based on the historical interpretation methods, this article investigates the role and influence of the three sources, namely, metaphysics, nature (macrocosm), and humans (microcosm), together with all the concepts, principles, and elements related to them on the theory and practice of artisans/ architects. The findings show that these authoritative sources, who reach a sacred status in a hierarchical system, have control over the formation of art/ architecture and the artisans' professional life. Indeed, the idea of authority played a decisive role and authority in organising the structure and content of artisans' guilds, granting holiness and legitimacy to their craft, determining authoritative models and patterns, and judging them. It seems that the theoretical formulation of the idea of authority and the concept of hierarchy of authoritative sources, in addition to describing some manners and principles of traditional professions, can provide a new explanation of the theoretical origins of the creation of form in the world of tradition.
