The purpose of this study is to investigate the effectiveness of ETF funds on Iran's stock market. The index investigated in this research is the degree of fragility of the stock market in Iran. For this purpose, a model has been used at first, which shows how much the entry of an ETF market fund can affect the stability and fragility of the stock market. Then, in order to analyze the issue, a series of ETF funds in Iran has been selected. We used price data of 21 different stocks included in ETF funds and the price of related ETF from 30-Jan 2022 till 28-Dec 2022. Using OLS regression analysis, the results and analysis give a pattern that with the entry of ETF funds, the nonsystematic value has increased values. Therefore, we conclude that the entry of ETF funds into the market increases the fragility in the Iranian stock market.

There is a vast line of research in misallocation like Hsieh and Klenow (2009), which see its roots in policy distortions. However, papers like Bill, Klenow, and Ruane(2020) argued differences in measured average products might reflect misspecification instead of actual marginal products. By focusing ...

There is a vast line of research in misallocation like Hsieh and Klenow (2009), which see its roots in policy distortions. However, papers like Bill, Klenow, and Ruane(2020) argued differences in measured average products might reflect misspecification instead of actual marginal products. By focusing on the Indian and Chinese manufacturing sectors, this paper shows that these results are sensitive to the parameters of the factor accumulation and the production function. Notably, the optimal dispersion depends on the parametrization, so one can't address the misallocation without a country-specific calibration of the model, we observe that the Hsieh and Klenow (2009) results are highly dependent on the measurement of the elasticity of substitution and capital share in production. Therefore, the assumption of the same parameters for all three countries could misguide us to a wrong measurement of the actual effects of misallocation. So we need to focus on the estimation of production function before any calculation on misallocation.

The present paper aims to test the new structural economics hypothesis in regard to the effect of development strategy on economic growth in a country that has witnessed an eight-year war and has suffered severe sanctions i.e., Iran. According to the new structural economics, if a country adopts a comparative advantage defying strategy, it will have poor growth performance. In contrast, to have a strong economic growth, it should employ a comparative advantage following strategy. the technology choice index (TCI) is utilized as a proxy of development strategy. Based on this indicator, increasing of TCI means that a country is conducting a comparative advantage defying strategy. The relationship is estimated by the ARDL bounds test approach. To run the model, the technology choice index (TCI), and a variety of control variables were included in the model. Hence, time-series data was collected from reliable databases for the period 1979-2018. The results in which their stability is checked, reveal a negative effect of adopting a comparative advantage defying strategy on economic growth, which supports Lin's hypothesis. In other words, it is shown that by increasing TCI, economic growth is declined significantly. So, to achieve economic growth, a kind of development strategy should be adopted that is based on pursuing comparative advantages.
