Abstract
Dominance of arid and semiarid climate in a vast area of Iran along with the water consumption growth necessitates a more sophisticated planning, a more efficient operation towards an optimal allocation and conservation of water resources in the country. In recent decades many countries, including Iran, have adopted increasing block tariffs for domestic water management. This policy is based on a progressive tariffs applied to control and manage the residential water consumption.
In this paper, we developed a panel data model to investigate the impact of increasing block pricing on the residential water consumption during 2004-2008. The average and marginal price models of demand for residential water have been estimated to examine the effects of households’ income and the climate conditions on the residential water consumption. Results show that the increasing block pricing system has not efficiently controlled the residential water consumption in Iran.

Abstract
The unmanaged control of liquidity growth has always been the concern of policymakers due to its negative consequences. Recently, policymakers have focused on the needing to control the liquidity growth. One of the liquidity drivers is the government borrowing from the central bank. In this regard, governments have concerned for the issue of not borrowing from the central bank since the 2000s onwards. Although governments are limiting themselves for this borrowing, they force banks and financial institutions to borrow from that source. For this purpose, this study designs a macroeconomic model by including the net debt of the public sector to the central bank as well as to banks and financial institutions via the government's financial balance channel. This model shows the relationships of economic variables in the framework of a stochastic dynamic general equilibrium (DSGE) model, considering nominal and real frictions. The results confirm the reliability of the model for simulating the economy of Iran after determining the input values and calibrating the parameters of the model using the Iran's economy data during 2000-2020. The findings from the research data show that the net increase in government sector debt to banks and non-banking credit institutions has a positive effect on investment, in such a way that new liquidity by the government obtained from institutions and banks It has been produced in the form of new deposits at the disposal of the department. The net impulse of public sector debt to the central bank causes an increase in consumption in the utility function and the total consumption of a combination of public goods and services provided by the government as well as private consumption goods and services. Also, the net impulse of public sector debt to the central bank causes an increase in inflation and a slight growth of production, and the net impulse of public sector debt to banks and credit institutions increases inflation and stimulates production.
