Consumption is the principal feature of Iran’s Gross National Production. Therefore, recognizing of factors that influence it is quite crucial. This article, investigates habit formation, durability, relative risk aversion and intertemporal substitution in consumption expenditures of Iranian households. For empirical study, at first, we constructed two weighted portfolio of the main assets re...

In this paper we find a possible continuation for quenching solutions to a system of heat equations coupled at the boundary condition. This system exhibits simultaneous and non-simultaneous quenching. For non-simultaneous quenching our continuation is a solution of a parabolic problem with Neumann boundary conditions. We also give some results for simultaneous quenching and present some numeric...

We consider solutions of normal form games that are invariant under strategic equivalence. We consider additional properties that can be expected (or be desired) from a solution of a game, and we observe the following: • Even the weakest notion of individual rationality restricts the set of solutions to be equilibria. This observation holds for all types of solutions: in pure-strategies, in mix...

extension of trade liberalization in countries is cause to increasing amount of goods in different sectors. exploit of global trade by increasing competitive power was regarded by researchers and policymakers in different countries. whereas abundance of production factor is one of the agent that makes advantage and qualitative land and labor force are two abundance production factors in agricul...

Aim/purpose – This paper aims to examine with new empirical evidence the joint rela- tionships between violence, income inequality, and real per capita in a simulta- neous equation framework using worldwide sample at country level. Design/methodology/approach To several simultaneous relationships variables, this study uses Seemingly Unrelated Regression (SUR) Three-Stage Least Squares (3SLS) tw...

We study a model of imperfectly discriminating contests with two ex ante symmetric agents. We consider four institutional settings: Contestants move either sequentially or simultaneously and in addition their types are either public or private information. We find that an effort-maximizing designer of the contest prefers the sequential to the simultaneous setting from an ex ante perspective. Mo...

empirical evidence seems to indicate that economic growth has varied inversely with natural resource abundance across countries, in which high natural resources dependent economies experience the low economic growth. this paper first reviews the literature of resources curse and shows that the most important challenges of economic development of iran are those mechanisms that change the blessin...

The ability to accurately assess others’ intents, beliefs, and emotions – called Theory of Mind (ToM) – is conjectured to be important for social cooperation. We study the role of ToM ability in fostering cooperation in the simultaneous and sequential prisoners dilemma (PD) games. Our norm-based model predicts that high ToM ability individuals will believe in more cooperation and cooperate at h...

This paper aims to provide a non-technical introduction into the SVAR methodology. Particular emphasize is put on the approach to identification in SVAR models, which is compared to identification in simultaneous equation models. It is shown that SVAR models are useful tools to analyze the dynamics of a model by subjecting it to an unexpected shock, whereas simultaneous equation models are bett...
