Using a threshold regression model and annual data (1960-2008), this paper examines the determinants of investment in Iran. We found that real GDP, the trade openness index and inflation can influence investment. However, the effect of inflation on investment follows an asymmetry adjustment...

The Iranian currency (rial) depreciated on average 12.2 per cent per annum against the U.S dollar during the period 1960-1998 but, despite continued two-digit rates of inflation, the rial has witnessed only a meagre 1.7 per cent fall in its value in the post 1998 era. This paper examines this...

The Zivot and Andrews (1992) one-break and Lumsdaine and Papell (1997) two-break unit root tests are used to investigate the random walk hypothesis in Thai stock prices for the period December 1987 to December 2005. The results provide strong evidence that the Thai stock prices are characterized...

This paper employs all available annual time series data to endogenously determine the timing of structural breaks for 10 macroeconomic variables in the Australian economy. The ADF (Augmented Dickey and Fuller) test and the LP (Lumsdaine and Papell, 1997) test are used to examine the time series...

This study employs all quarterly time series currently available to endogenously determine the timing of structural breaks for various monetary aggregates and interest rates in Australia over the last 30 years. The Innovational Outlier model (IO) and the Additive Outlier model (AO) are then used...

This paper employs all quarterly time series currently available to determine endogenously the time of structural breaks for three monetary aggregates—the long- and short-term interest rates as well as the consumer price index—in Australia using the ZA (Zivot and Andrews, 1992) test and the...

Over the past few decades the brisk development of information and communication technologies (ICT) has had a phenomenal impact on the economic stability and development of many countries. Empirical studies show that most developed economies have gained significant payoffs (in terms of economic...

This dissertation examines the major determinants of GDP growth in Iran using annual time series data spanning the years from 1960 through 2003. The Iranian economy has been subject to a multitude of structural changes and regime shifts during the sample period. Thus after applying conventional...

Most research on performance evaluation of agricultural crops in Iran analyzes technical efficiency with estimation of stochastic production function. In this paper in spite of past research we survey cost efficiency with panel data. Information about input prices, yield and production cost per...
