Hicks on monetary theory and history: money as endogenous money

Hicks was never tired of saying that monetary theory is in history.What he meant was that monetary theory is intrinsically relatedto real events, and more importantly that monetary issues needto be analysed in a dynamic sequential context in which timeplays an essential part. He went on developing a particularsequential analysis: the study of what happens within a singleperiod (‘single-period theory’) and the study ofthe linkages between a succession of those periods (‘continuationtheory’). It is suggested that this distinction providesa useful lesson for modern endogenous money theorists.     

Insights on endogenous money and the liquidity preference theory of interest

It is argued that the debate between “structuralist” and “horizontalist” has long been obscured because of inadequate treatment, in both approaches, of the credit-money supply and of the total money supply. As a result, endogenous money models still have serious limitations today. On the one hand, the bank loan markup and the loan interest rate are exogenous in the horizontalist model, which supposes that they do not depend on the money/liquidity market conditions (as if bank loans did not compete with the existing liquidity). On the other hand, although interest rates are endogenous in the structuralist model, they result from inappropriate treatment of the loan supply and money/liquidity supply. This article aims to remove these shortcomings. It offers a theoretical framework and formal modeling where the creditworthy demand for loans determines the bank loan supply, given the central bank refinancing interest rate, while the total supply and demand for liquidity-money determines the markup and the market rate of interest in accordance with Keynes’s liquidity preference theory. In this framework, the post Keynesian theory of endogenous money and Keynes’s “verticalist” view prove to be analytically complementary.     

Further insights on endogenous money and the liquidity preference theory of interest

Abstract

We present a simple stock-flow consistent (SFC) model to discuss some recent claims made by Angel Asensio in a paper published in this journal regarding the relationship between endogenous money theory and the liquidity preference theory of the rate of interest. We incorporate Asensio’s assumptions as far as possible and use simulation experiments to investigate his arguments regarding the presence of a crowding-out effect, the relationship between interest rates and credit demand, and the ability of the central bank to steer interest rates through varying the stock of money. We show that in a fully-specified SFC model, some of Asensio’s conclusions are not generally valid (most importantly, the presence of a crowding-out effect is ambiguous), and that in any case, his use of a non-SFC framework leads him to leave aside important mechanisms which can contribute to a better understanding of the behavior of interest rates. More generally, this paper once more demonstrates the utility of the SFC approach in research on monetary economics.     

Schumpeterian endogenous growth theory and evolutionary economics

In this paper, we aim to discuss whether Schumpeterian models of endogenous growth can accommodate Schumpeters vision of development through creative destruction. Taking a methodological approach, our focus is on individual decision-making, technology, general equilibrium and welfare, and steady state dynamics as the fundamental principles underlying endogenous growth theory. In particular, the Aghion-Howitt model of Schumpeterian growth in various extended versions is analyzed in the light of Schumpeters work. Therefore, we also try to root Schumpeters work in historical context. We find endogenous growth theory far from carrying Schumpeters idea of an evolutionary approach to change and development. Rather the emergence of numerous models of an evolutionary type can be observed to provide for the formal structure appropriate to keeping Schumpeters legacy alive.JEL Classification: B1, B2, B4, O3, O4Corespondence to: Thomas Kuhn     

Post Keynesian endogenous money theory: A theoretical and empirical investigation of the credit demand schedule

The article investigates the relationship between interest rates and loan amounts provided by commercial banks from both a theoretical and an empirical perspective. Theoretically, some scholars belonging to the post Keynesian endogenous money tradition advocate that a decrease (increase) in interest rates leads to a positive (negative) effect on the amount of loans demanded by households and firms. On the other hand, some heterodox economists maintain that interest rates do not stimulate firms’ credit demand but that a certain degree of influence is allowed for loans provided to households. By applying a vector autoregression (VAR) and vector error-correction model (VECM) methodology to European Central Bank and Organisation for Economic Co-operation and Development data for the eurozone, this article proposes an empirical validation of such theoretical premises by analysing the relationship between the different types of credit provided by commercial banks and the corresponding interest rates. The main results show a negative relationship between the interest rates and the credit provided for the purchase of houses. Conversely, no significant relationship is found between loans granted to enterprises and loans for the purchase of consumption goods and the corresponding interest rates.     

Does modern endogenous growth theory adequately represent Allyn Young?

Endogenous growth theory is now fashionable. It seeks to explainwhy per capita income growth in capital abundant countries isoften faster than in capital poor countries and defies the operationof diminishing returns. This theory, which took off with Romerand Lucas, often makes Allyn Young's concept of increasing returnsand Marshall's distinction between internal and external economiesits starting point but considers their treatment of the subjectas not sufficiently rigorous. The modern endogenous growth theoriststhen claim to explain what they had in mind with greater clarity,rigour and depth. This paper argues that this is not the caseas these theorists actually misrepresent Young in importantways.     

The nature and role of monetary policy when money is endogenous

This paper considers the nature and role of monetary policywhen money is modelled as credit money endogenously createdwithin the private sector. There are currently two schools ofthought that view money as endogenous: one has been labelledthe ‘new consensus’ in macroeconomics, and the otheris the Keynesian endogenous (bank) money approach. The paperfirst explores the analysis of monetary policy in the ‘newconsensus’ macroeconomic model, followed by an examinationof the effectiveness of monetary policy in that analysis. TheKeynesian view of endogenous money is discussed, and the rolefor monetary policy in a Keynesian endogenous monetary policyanalysis is considered, including discussion of the objectivesand instruments of monetary policy.     

Monetising the Classical Equations: a theory of circulation

The Classical Equations describe output and income in real terms.To use them to analyse aggregate demand, the transactions theydescribe must be ‘monetised’. A sum of money equalto the wage bill of the capital goods sector can be shown tobe necessary and sufficient to carry out all transactions, ina process of circulation which also defines an expression forvelocity. When money has intrinsic value, the quantity approachmay hold in the short run but, in the long run, money will beendogenous. In these conditions, the rate of interest will bedetermined by the supply and demand for reserves, but when moneyis purely nominal, only a minimum rate will be fixed, and therate of interest will have to be pegged. The Appendix developsthe Classical Equations and shows that they define an invariableunit of account.     

Health and infrastructure in a model of endogenous growth

This paper studies the optimal allocation of government spending between infrastructure and health (which affects labor productivity as well as household utility) in an endogenous growth framework. A key feature of the model is that infrastructure affects not only the production of goods but also the supply of health services. The rate of time preference is also endogenously related to health outcomes. The first part considers the case where health enters as a flow in production and utility, whereas the second focuses on a “stock” approach. Growth- and welfare-maximizing rules for income taxation and the allocation of public spending are derived.     

Business cycles in a two-sector model of endogenous growth

Summary. This paper analyzes the impact of cyclical volatility on long-term economic growth: does growth increase or decrease with increased cyclical volatility? We construct a stochastic two-sector model of endogenous growth to analyze this question in detail. We will show that economic growth is higher in the presence of business cycles, since people devote more time to learning activities in an uncertain economic environment. Human capital is a hedge against future income uncertainty. Hence, the rate of economic growth will be higher in a stochastic environment. Based on a calibration of the model, we find that economic growth increases by 0.46%-point as a result of observed business cycle variability. When account is taken of the interaction between the model's general equilibrium and the cycle, welfare gains (measured in units of a permanent percentage increase in consumption) from eliminating business cycle volatility are approximately 1.87%.

Efficiency, depth and growth: Quantitative implications of finance and growth theory

We develop a parsimonious finance and endogenous growth model with microeconomic frictions in entrepreneurship and a role for credit constraints. We demonstrate that though an efficiency–growth relation will always exist, the efficiency–depth–growth relation may not. This has implications for the connection between the theory and empirics of finance and growth. We go on to ask whether the model can account for some historical trends in growth, financial depth and financial efficiency for the UK over the period 1850–1913. The best model of finance and growth is one that departs from the standard depth–growth link.

Recursive equilibrium in endogenous growth models with incomplete markets

This paper analyzes the existence of recursive equilibria in a class of convex growth models with incomplete markets. Households have identical CRRA-preferences, production displays constant returns to scale with respect to physical and human capital, and all markets are competitive. There are aggregate productivity shocks that affect aggregate returns to physical and human capital investment (stock returns and wages), and there are idiosyncratic shocks to human capital (idiosyncratic depreciation shocks) that only affect individual human capital returns. Aggregate and idiosyncratic shocks follow a joint Markov process. Conditional on the aggregate state, idiosyncratic shocks are independently distributed over time and identically distributed across households. Finally, households have the opportunity to trade assets in zero net supply with payoffs that depend on the aggregate shock, but markets are incomplete in the sense that there are no assets with payoffs depending on idiosyncratic shocks. It is shown that there exists a recursive equilibrium for which equilibrium prices (returns) only depend on the exogenous aggregate shock variable (the wealth distribution is not a relevant state variable). Moreover, the allocation associated with this recursive equilibrium is identical to the equilibrium allocation of an economy in which households live in autarky and face both aggregate and idiosyncratic risk.I would like to thank for helpful comments Peter Howitt, Bob Lucas, Michael Magill, Tomo Nakajima, Herakles Polemarchakis, Martine Quinzii, Kevin Reffett, an anonymous referee, and seminar participants at various universities and conferences.     

Government financing in an endogenous growth model with financial market restrictions

Summary. In this paper, we develop an endogenous growth model with market regulations on explicitly modeled financial intermediaries to examine the effects of alternative government financing schemes on growth, inflation, and welfare. In the presence of binding regulation, there is always a unique equilibrium. We perform four alternative policy experiments; a change in the seigniorage tax rate, a change in the seigniorage tax base, a change in the income tax and a change in the fiscal-monetary policy mix. We find that in the presence of binding legal reserve requirements, a marginal increase in government spending need not result in a reduction in the rate of economic growth if it is financed with an increase in the seigniorage tax rate. Raising the seigniorage tax base by means of an increase in the reserve requirement retards growth and it has an ambiguous effect on inflation. An increase in income tax financed government spending also suppresses growth and raises inflation although not to the extent that the required seigniorage tax rate alternative would. Switching from seigniorage to income taxation as a source of government finance is growth reducing but deflationary. From a welfare perspective, the least distortionary way of financing an increase in the government spending requirements is by means of a marginal increase in the seigniorage tax rate. Under the specification of logarithmic preferences, the optimal tax structure is indeterminate. Received: March 20, 2000; revised version: June 26, 2001     

A dynamic analysis of an endogenous growth model with leisure

Summary. The main goal in this paper is to analyze an economic model of endogenous growth where human capital accumulation acts as the engine propelling economic activity. The added ingredient in our model is that agents derive utility from consumption and leisure, where leisure is defined as the amount of time devoted to those activities augmented by the level of education. Under regular conditions we show that there is a unique globally stable balanced growth path. We also provide a characterization of the behavior of our economic variables along the transition.

A Schumpeterian model of endogenous innovation and growth

A disequilibrium model of endogenous innovation and growth is presented. The behaviour of the agents is supposed to be governed by routines, not by maximization. The entrepreneurs are assumed to invest a fraction of their operating profits in real capital accumulation, and another fraction in R&D. The latter leads to an increase in labour productivity via a R&D production function. In this Schumpeterian model, not only the R&D processes of innovations are considered, but the diffusion processes as well. As in Schumpeter's theory of economic development the economic impact of technical change is considered a disequilibrium phenomenon. Thus, in a capitalist economy characterized by ongoing diffusion processes of innovations, time averages are more important than steady state values even in a long run perspective.     

Optimal monetary policy in a New Keynesian model with endogenous growth

We study optimal monetary policy in a New Keynesian (NK) model with endogenous growth and knowledge spillovers external to each firm. We find that, in contrast with the standard NK model, the Ramsey dynamics implies deviation from full inflation targeting in response to technology and government spending shocks, while the optimal operational rule is backward looking and responds to inflation and output deviations from their long-run levels.     

Culture and human capital in a two-sector endogenous growth model

Recent literature in the field of cultural economics highlights a possible inversion in the usual causality relation (from economic growth to culture) and points out that culture may represent an important driver of economic growth. By viewing culture in line with Throsby’s (2001) definition of cultural capital (i.e., an asset of tangible and intangible cultural expressions), in this article we analyze one possible channel through which culture may positively affect economic growth, namely the existence of a relationship of complementarity between cultural and human capital investments. Using a two-sector endogenous growth model, we find that in the long run a higher growth rate of real per-capita income can be attained the more cultural and human capital investments are complementary for each other in the process leading to agents’ skill acquisition. We also analyze the conditions under which an increase of the cultural capital share in total GDP can be conducive to a rise of real per-capita income.     

Financial institutions and the Cambridge theory of distribution

This paper shows how the Cambridge theory of distribution isaffected by the nature of financial intermediation. When creditmarkets are akin to loanable funds markets in which lenderstransfer resources to borrowers, the Cambridge theory holdsand steady-state income distribution is independent of workers'saving behaviour. However, when credit markets embody endogenouslygenerated bank money, the Cambridge theory does not hold. Financialinstitutions and endogenous money therefore matter for long-runsteady-state outcomes, just as they do for short-run macroeconomicoutcomes.     

Real Indeterminacy in Monetary Models with Nominal Interest Rate Distortions

This paper demonstrates that in a standard flexible-price monetary model there exists real indeterminacy whenever the nominal interest rate moves too closely with either current or forecasted inflation. However, an aggressive response to lagged inflation will ensure determinacy. These conclusions are robust to a wide range of calibrations, and a monetary environment that allows for endogenous velocity. The results are affected by the inclusion of investment spending in the transactions constraint. Journal of Economic Literature Classification Numbers: E4, E5.
