t his paper investigates the asymmetric behavior of inflation. we use logistic smooth transition autoregressive (lstar) model to characterize the regime-switching behavior of iran’s monthly inflation during the period may 1990 to december 2013. we find that there is a triple relationship between the inflation level, its fluctuations and persistence. the findings imply that the behavior of infla...

abstract i n this paper, we investigate the existence and the nature of real exchange rate misalignment in organization of the petroleum exporting countries (opec). to do this we estimated a cross country basic real exchange rate determination model for 1990-2012 and extracted historic trend of misalignment. the results imply that all opec countries have had misalignment -of different kinds tho...

The study of Artificial Neural Networks derives from first trials to translate in mathematical models the principles of biological “processing”. An Artificial Neural Network deals with generating, in the fastest times, an implicit and predictive model of the evolution of a system. In particular, it derives from experience its ability to be able to recognize some behaviours or situations and to ...

JEL Classification Code(s): J 31, J 71) "Perceptions of Discrimination, Effort to Obtain Psychological Balance, and Relative Wages: Can We Infer a Happiness Gradient?" There is a substantial literature that finds a linkage between happiness and relative economic well being as measured by earnings or wages. There is also a well documented racial gap in wages. One explanation for this is disparat...

We develop a model of complex undescribable contingencies. These are contingencies that are understood by economic agents — their consequences and probabilities are known — but are such that every description of such events necessarily leaves out relevant features that have a non-negligible impact on the parties’ expected utilities. Using a simple co-insurance problem as backdrop, we introduce ...

abstract: decentralization is a process in which local affairs are administrated by local authorities outside of activities of the central government. today, decentralization policy is considered as one of the ways that most countries adopted to improve public sector performance. in this paper using geometric analysis, innovation that this paper represents, an econometric model is considered to...

s tructural change is defined as a change in the relative weight of the important constituents of the macro-economic indicator such as production, taxes, imports and exports, workforce etc. since the structure change is one of the main reasons for the growth and economic development of countries, the investigation of the trend of changes in economic important constituents is important. tax as a...

This paper aims to identify key challenges facing Iran and South Korea in their bilateral trade and investment relations. In particular, it is concerned with the policy implications which can be useful for policy makers and business people of both countries. For this purpose, we review and analyze the recent developments of the Iranian economy and bilateral trade and investment relations betwee...

This paper argues that a generalized model of social preferences must simultaneously pass two tests; the Variety Test (explain outcomes under variety, the V-test) and the Psychological Test (conform to psychological intuition, the P-test). It is shown that none of the models proposed to date unconditionally passes these tests. The paper extends the Fehr and Schmidt model of inequality-aversion ...

We decompose labor-productivity growth into components attributable to (1) technological change (shifts in the world production frontier), (2) technological catch-up (movements toward or away from the frontier), (3) human capital accumulation (changes in the efficiency of labor), and (4) physical capital accumulation (movement along the frontier). The world production frontier is constructed us...
