Many studies explore only use or non-use of capital budgeting methods, and not the factors that determine the selection of the method used in UAE or the region. The relationships between use and independent variables that affect the selection of the method have been studied. The study attempts to fill a gap in the existing literature of capital budgeting practice in the developed and developing...

Oil price shocks are the major source of economic instability in oil exporting developing countries, including Iran. In this paper a Multi Sector Dynamic Stochastic General Equilibrium model, with emphasis on optimization of oil sector as a producing sector is designed. Furthermore, an optimizing import sector is introduced into the model by considering the price rigidity in imported goods as a...

In this paper we intend to examine the application of Kullback-Leibler, Hellinger and LINEX loss function in Dynamic Linear Model using the real price of oil for 106 years of data from 1913 to 2018 concerning the asymmetric problem in filtering and forecasting. We use DLM form of the basic Hoteling Model under Quadratic loss function, Kullback-Leibler, Hellinger and LINEX trying to address the ...

This paper presents a toolkit for generating optimal policy projections. It makes five contributions. First, the requires minimal set of inputs: only baseline projection target and instrument variables impulse responses those to shocks. Second, it solves projections under commitment, limited-time discretion. Third, handles multiple instruments. Fourth, constraints on instruments such as lower b...

This paper evaluates the interacted effects of the fiscal and monetary policies on the nominal and real macro-variables of the Iranian economy. Our analysis is thus based on the optimal control theory by which the optimal path of the control variables including monetary and fiscal tools are determined over the period 1963-2006. We also use a macro-econometric model in form of a simultaneous equ...

We study a continuous-time problem of optimal public good contribution under uncertainty for an economy with a finite number of agents. Each agent can allocate his wealth between private consumption and repeated but irreversible contributions to increase the stock of some public good. We study the corresponding social planner problem and the case of strategic interaction between the agents and ...

For portfolio choice problems with proportional transaction costs, we discuss whether or not there exists a shadow price, i.e., a least favorable frictionless market extension leading to the same optimal strategy and utility. By means of an explicit counter-example, we show that shadow prices may fail to exist even in seemingly perfectly benign situations, i.e., for a log-investor trading in an...

How to determine how much and what produce? This is one of the great unknowns in economics. paper proposes study recipes offered by conventional economics, keynesian Economics, Austrian school questioning use assumptions mathematical tools. In addition, we will analyze concept dynamic efficiency, which provides a contribution debate. The importance analyzing various focuses on highlight that mi...

The Journal of Economic Literature codes classification system (JEL) published by the American Association (AEA) is de facto standard for research literature in economics. JEL used to classify articles, dissertations, books, book reviews, and working papers EconLit, a database maintained AEA. Over time, it has evolved extended with over 850 subclasses. This paper reviews history development sys...
