The government's public expenditure has grown rapidly over the years, which is believed to have a significant impact on the country's financial performance. Due to the existence of consequences due to the expansion of government spending on the economy, it is necessary to understand the factors that cause the growth of government spending. For this purpose, this study uses a modified version of Wagner's law by combining new variables such as oil income, trade openness, public debt, exchange rate, domestic production, taxes and inflation to determine their effect on the size of government spending in Iran using To examine the time series data between 1978 and 2019 with the autoregression method with distributed lag (ARDL). The findings of this study show that oil revenue, GDP, population, trade openness, taxes, inflation, and public debt are important determinants of government spending. The short-term and long-term results confirm Wagner's law in Iran and show that the effort to develop and diversify has forced the government to expand public spending by building public infrastructure (railways, electricity, etc.).

Wagner law is the first model of government expenditures in the public finance literature. In addition to testing the traditional version of Wagner's law, also the augmented version of this law, which is introduced by Murthy (1994) is examined in order to find a long-term relationship between government spending and economic development in Iran. The main objective of this study is to evaluate a short-term and long-term relationship between government expenditures (per capita) and GDP (per capita) using annual data for the Iranian economy during the period 1392-1357. Therefore, in this article, the validity of this relationship is checked by six different formulations of the Wagner Law (the desire to increase government spending by economic growth), and the causality between variables are considered with using boundary F-test and error correction model (ECM). Among the studied models, the Wagner law is executable in terms of income elasticity only in Peacock and Musgrave version and in generalized version. The results of the Bound Test indicate that long-term relationship between the variables exists in three versions of Wagner’s law. In addition, causality test with using an error correction model represents a one-way path from the income on government spending for short periods in five models. Overall, the results show that the Wagner law is confirmed in the third group of models for short-run in the Iranian economy.

The determination of factors affecting government expenditure has been raised in the economy of public sector from the long ago. Adolf Wagner (1967)، the German economist has studied the growth of public sector of some European countries، the United States and Japan، and his theory is based on these experiences. Based on the theory، by increasing income in these countries، the government expenditure has increased more. Most of the studies conducted on the Wagner theory have been at the macro-level for Iran or between country، and only one study has been done in provinces of the country by cross section data for 1994. In this study، it is tried the impact of the economy size (income and per capita income) on the size of the government (government expenditure، government expenditure relative to income and per capita government expenditure) in the form of Four Alternative Specification of the Wagner''s hypothesis for the provinces of Iran in 2001-2012 are to taken into account using the panel data. For this purpose، the effect of income، population density، the urbanization rate and the unemployment rate are examined on the size of the government. The results indicate the acceptance of Wagner’s law in provinces of Iran.

Over the past few decades, the validity of Wagner’s law has been studied in many countries. According to this law, economic growth has led to the growth of the public sector. Our goal in this paper is to explore the validity of Wagner’s law in Iran during the period 1349-1389 for real oil GDP and non-oil GDP. We used econometric techniques to examine how far Wagner’s law could be applied to Iran’s economy during that period of time. The results suggest that a long-run relationship exists between variables in the case of total GDP. In the case of non-oil GDP, however, Wagner’s law has been applicable in all the six interpretations. According to the error correction model, in the case of non-oil GDP, there is only one valid interpretation of the Wagner law (i.e. Peacock-Wiseman). This result has been confirmed by the Granger causality test. Thus, the validity of Wagner's law is proved in one interpretation in the oil sector and all the six interpretation in the non-oil sector.

This paper studies the validity of Wagner law in selected OIC (Organization of Islamic Conference) member states by classifying them based on their income levels and degrees of corruption. For doing so، the Pesaran Cross-sectional Dependency (CD) test، cross-sectional augmented ADF (CADF) as well as Wasteland and Edgerton''s panel co integration tests have been employed. To estimate the coefficients، the continuous-updated and fully modified (CUP-FM) estimator has been used. The results confirm validity of Wagner law in all economies، having different income levels and corruption degrees.

One of the most well known methods for explaining the growth in public sector is Wagner's law, which explains the growth of government size. Wagner argues that the more per capita income in economy, the bigger would be the government size. Using panel data method, this paper is analyzing Wagner's law for Iran and southeastern Asian countries. The results confirm the consistency of Wagner's law for both Iran and those selected countries.
