the main purpose of this paper is analyses the short and long run relationship between budget deficit and trade deficit in some mena countries. the data cover the period from 1971-2000 (and for i.r. iran 1 959-2003).the relationship between these variables will be analyses in short and long run by using johansen cointegration tests, ecm, and granger causality test. the empirical evidence provid...

The Purpose of this paper is to investigate the long-run effect of real effective exchange rate on Iran non-oil trade balance. The methodology is based on ARDL procedure that can be applied irrespective of whether the regressors are I(0) or I(1). The results show the real depreciation has not a favorable long - run effect on the non-oil trade balance of Iran from 1979 to 2001.

Theory tells us that output, the capital stock and the user cost of capital are cointegrated. From the capital accumulation identity, it also follows that the capital stock and investment have a long-run proportional relationship. This has been used to justify the estimation of investment equations embodying a long-run relation between investment and output, rather than between the capital stoc...

We model and analyze strategic interaction over time in a duopoly. Each period the …rms independently and simultaneously take two sequential decisions. First, they decide whether or not to advertise, then they set prices for goods which are imperfect substitutes. Not only the own, but also the other …rm’s past advertisement e¤orts a¤ect the current ‘sales potential’ of each …rm. How much of thi...

This paper uses recent developments in measuring correlation to examine the relationship between inflation and relative price variability. The results suggest that the positive correlation holds not only in the short-run but also in the long-run. This finding has important implications for theoretical models that purport to explain this relationship: such models must incorporate features that g...

T he main aim of this study is to investigate the impacts of population total, gross domestic product per capita, urbanization rate and energy use on carbon emissions in Nigeria for a period of 1981-2015 using autoregressive distributed lag approach to co-integration (ARDL). The empirical results revealed evidence of a long run relationship among the variables. The generalized ridge ...

Ambiguous beliefs may lead to speculative trade and bubbles. We demonstrate this by showing that the classical Harrison Kreps (1978) example of among agents with heterogeneous can be replicated having common but ambiguous beliefs. More precisely, we show same asset prices pattern obtained in equilibrium agents' recursive multiple-prior expected utilities set priors. While learning about true pr...

this study attempts to investigate the effect of oil returns and external debt on the government expenditure in syria over the period 1970-2010. the johansen cointegration test showed that oil returns and external debt have a positive and significant long run relationship with government expenditure. the granger causality test indicates unidirectional short-run causality relationships running f...
