The purpose of the present article is to investigate the impact of fiscal corruption on government tax revenues and government expenditure in selected developing countries. To do so, by using from panel data method and statistical information of years (2000-2007) for 31 developing countries, the impact of fiscal corruption and other independent variables on government tax revenue and government expenditure have been investigated. The results show that, following the increase in fiscal corruption reduce government tax revenue relative share of gross domestic product. That means a negative impact on government tax revenues, the results also indicate that because of increase in corruption index (reduced levels of corruption), government expenditure increases as a percentage of gross domestic product.

Abstract:
In this paper, the effect of social capital on the efficiency of government expenditures has been studied in the two sectors of education and health during the period 1364-1396. social capital has been estimated by The Multiple Causes-Impact (MIMIC) approach, and efficiency of government expenditures in both education and health is estimated by the Data Envelopment Analysis (DEA) and Bootstrap data envelopment analysis approaches. The effect of social capital on the efficiency of government expenditures are measured by the regression model of the deficit probe in both education and health.
 The results of estimating social capital show that the trend of social capital is declining by the method of  Multiple Indicators and Multiple Causes during the study period. Also, the efficiency scores of government expenditures has been measured by Data Envelopment Analysis and Bootstrap Data Envelopment Analysis in Iran. The results show that on average, public spending is inefficient in education and health.
Findings of the fractional probit model show, the effect of social capital is positive and significant on the efficiency of government spending in both education and health. The effect of per capita income, economic growth, government size, inflation and trade openness is different on efficiency of government expenditures in education and health sectors.
 For example, the impact of economic growth­ is positive on the efficiency of government education and health spending. While the effect of government size is negative on the efficiency of government education and health spending.

The existence of a structural budget deficit in Iranian economy and the lack of fiscal discipline have raised concerns about the financial stability of governments among economists. In recent decades, fiscal rules have been considered as a way to establish fiscal discipline and financial sustainability of governments around the world. In this regard, the present study seeks to design a fiscal framework based on the three rules of debt ceiling, budget balance and expenditure for Iranian economy. The results of applying the stochastic simulation method show a high level of current public debt compared to the debt rule ceiling estimated by the model and the budget balance rule will be greatly effective in improving the future path of public debt. In other words, applying the budget balance rule reduces the fluctuations of the future path of public debt. It is also suggested to establish an institutional mechanism as a complementary institution with the aim of improving the performance and effectiveness of fiscal rules, especially for expenditures rule and ensuring their implementation
