This paper replicates them on the orbit of a neokeynesian dynamic stochastic general equilibrium (NK-DSGE) model characterized in particular by macroeconomic agents and derived from start to finish. Trust is specifically modeled as an endogenous variable characterized by a coalescence of three processes governed by a degree of volition, the processes being permanent technology, transient technology, and noise technology. The first two processes affect the actual production technology with a delay of one lag, while the third does not at all. The short-run responses to changes in confidence are shown whenever the degree of willingness allows confidence to change real consumption and aggregate labor, thus being non-negligible. Whenever the degree of volition was, by contrast, negligible, exogenous shocks in noise technology would cause no fluctuation in actual consumption and actual power.","PeriodicalId":367341,"journal":{"name":"Journal of Mathematical Economics and Finance","volume":"14 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-06-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127287152","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Thus, the general equilibrium does not need money metrics, unspeci ed money market and the complementing inappropriate incorporation of the Walras Law. Further, the main function of money is not that of a unit of account, but a means of exchange. If such type of a money market is introduced, the Walras symmetry holds but in the sense that the positive aggregate excess demand on the goods market matches the negative excess demand on the money market. Distinction is de ned between neoclassical, relative and monetary prices. Additional conditions must be met to allow for a closed monetary circulation.","PeriodicalId":367341,"journal":{"name":"Journal of Mathematical Economics and Finance","volume":"31 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-06-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115242939","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The equation of exchange is derived from a standpoint encompassing the physics and economics thereof, whereby the maximisation of a money value function, increasing in real output and decreasing in the real money supply, while accounting for time and space, subjected to a money constraint, at the macroeconomic level, gives rise to an optimal level of real output thereby, expressing the liquidity demand coefficient as the inverse quotient of space over time. The fusion of such a liquidity demand coefficient expression with the money constraint, which is the equilibrium Cambridge equation, in turn gives rise to an equation for space, being the position of money, whose differentiation is precisely instantaneous money velocity and thence the exchange equation as presented by Fisher. The present analysis also derives money position on account of non-constant instantaneous money velocity as instantiated by Fisher, advancing a framework for the macroeconomy’s general money value function and money constraint in the process. It likewise advances simulations of non-constant average and instantaneous money velocity, with a particular application to a stylised closed macroeconomy. It finally proceeds to remodel instantaneous money velocity through the use of ordinary differential equations (ODEs) for the money equations of motion, both generally, by letting the sum of the three equal a corrected exponential random walk with drift, and through a money force model, of free accumulation with financial assets resistance. This work thus remarks in sum that money velocity as customarily calculated, taught and understood is not univocal. \u0000 \u0000 \u0000","PeriodicalId":367341,"journal":{"name":"Journal of Mathematical Economics and Finance","volume":"79 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-12-31","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116753852","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
