Abstract

A B S T R A C T 
Monetary policy refers to the set of measures that monetary policymakers employ to control economic activities and achieve economic objectives. The impact of monetary policy on various micro and macroeconomic sectors takes shape through a process known as the monetary policy transmission mechanism. This process begins with the application of monetary policy tools and culminates in output and other final real economic variables. The objective of this article is to examine the effect of monetary policy on the performance of firms facing financial constraints. For this purpose, quarterly data from 79 non-financial firms active in the Tehran Stock Exchange during the period from the second quarter of 2013 to the first quarter of 2024, along with the Generalized Method of Moments (GMM) technique, were used. Initially, the role of the balance sheet channel on firm performance was confirmed, indicating that these firms face financial constraints. Furthermore, with the implementation of expansionary monetary policy, the impact of financial constraints on firm performance diminished. Finally, one of the economic variables affecting firms' ability to cope with financial constraints was their asset size, which was incorporated orthogonally into the final model. The results indicated that as size increases, due to a reduction in the degree of financial constraints, the sensitivity of firm performance to the monetary policy implemented by economic policymakers decreases. Consequently, the impact of financial constraints on the composite index of firm performance changed from -0.8065 in the initial model to -0.0631 in the final model, which included the firm size variable.
