تاثیر ورود رمز پول به عنوان جانشینی برای پول رایج در یک مدل dsge برای اقتصاد ایران

یکی از واژه‌هایی که در زندگی عصر حاضر به گوش می‌خورد، ارز دیجیتال است. ارز دیجیتال یکی از اجزای سیستم مالی غیر متمرکز جهت تسهیل مبادلات اقتصادی است که دست واسطه‌ها مثل بانک را تا حد ممکن از معاملات کوتاه می‌کند. یکی از اهداف رمزپول‌ها این بود که به مردم قدرت کنترل پول را بدهند و به بیان ساده واسطه‌ها (مثل بانک‌ها) را حذف کند. علی‌رغم ایجاد رمز پول‌ها و گسترش مبادلات این نوع ارزها هنوز ردپایی از این تکنولوژی جدید در مدل‌های اقتصادی از جمله مدل‌های مالی- پولی دیده نشده است. بنابراین هدف از این پژوهش بررسی این موضوع است که ورود رمزپول چه دلالت‌هایی بر اقتصاد خواهد داشت که برای تحقق هدف پژوهش از روش ورود رمز پول به مدل‌های dsge استفاده خواهد شد. نتایج نشان می‌دهد که یک اثر جانشینی قوی بین مانده حقیقی پول رایج و مانده حقیقی رمز پول در پاسخ به فناوری، ترجیحات و شوک‌های سیاست پولی وجود دارد. علاوه بر این مقایسه نتایج حاصل از پژوهش افزایش در تولید و تورم زمانی ‌که رمزپول در مبادلات وجود نداشته باشد نسبت به زمانی که رمزپول در مبادلات وجود داشته باشد، بیشتر است. این امر نشان از وجود تورم بیشتر در زمان عدم وجود رمزپول است.

the impact of cryptocurrency as a substitution for government currency on the iranian economy in a dsge model

introduction: one of the words that is heard in the present life is digital currency digital currency is a component of a decentralized financial system to facilitate economic transactions through evicting intermediaries such as banks as much as possible. in the meantime cryptocurrency is a digital or virtual currency that is secured by cryptography and made nearly impossible to counterfeit or double-spend. in the early 1990s, some elite people intended to give more freedom to the people through the use of the internet and reduce the power of governments. the main goal of these elites was to empower people to control money and information and to simply eliminate intermediaries such as banks.methodology: templates based on time series equations are a new type of economic modelling that dates back to the early 1970s. time series patterns include a wide range of economic patterns, the most important of which is the vector auto regression pattern. time series equations can be extracted in two ways, including a method of inference from theory and then modelling according to the researcher and the relevant statistical tests to determine the accuracy of the model and the estimated parameters. this type of modelling faces several problems such as unstructured parameters, structural shock detection, and specification error. due to the nature of partial equilibrium, they sometimes have difficulty understanding the economic conditions and erroneous predictions. the problems are due to the difference between the model and the economic theory. to solve these problems, dynamic stochastic general equilibrium (abbreviated as dsge, or dge, or sometimes sdge) models were used. this kind of modelling is a macroeconomic method often employed by monetary and fiscal authorities for policy analysis, explaining historical time-series data as well as future forecasting purposes. the present study has used the dsge method to estimate the model. in this model, it is assumed that households gain utility from consumption, government currency and cryptocurrency, and labor supply has inutility for those households. therefore, they try to maximize its utility by using their budget constraint. another part of this study is the entrepreneurial section (cryptocurrency miners), which assumes that there is a continuous chain of entrepreneurs denoted by n, and that each entrepreneur operates under conditions of perfect competition. the third part is the manufacturing firm, which assumes that firms are different in an exclusive competitive environment for the production of intermediate goods and have access to other intermediate goods of other firms to produce a final product under perfectly competitive market conditions. the last section is the central bank, which determines the monetary policies governing the society. in this study, it is assumed that the central bank uses the nominal interest rate as a rule set in a modified taylor (1993) model.results and discussion: this model is estimated using the monthly data of iran, and the results show that there is a strong substitution effect between the government currency real balance and the cryptocurrency real balance in response to technology, preferences and monetary policy shocks. in addition, government currency demand shocks have a greater impact on the economy than the cryptocurrency demand. cryptocurrency productivity shocks also lead to a decline in the nominal exchange rate. production and inflation decrease when nominal interest rates increase. however, the effects of these shocks are much less than those of traditional shocks.conclusion: overall, this study provides new insights and evidence on the underlying mechanisms of cryptocurrency and its effects on the economy.
