RE‐EXAMINING THE IMPLICATIONS OF THE NEW CONSENSUS: ENDOGENOUS MONEY AND TAYLOR RULES IN A SIMPLE NEOCLASSICAL MACRO MODEL

This paper re‐examines the impact of endogenous money in a neoclassical model with interest‐sensitive expenditures. It first outlines a benchmark model with exogenous money and the usual full employment and money growth‐determined inflation results. It then replaces exogenous money with endogenous money, which is shown to generate model indeterminacy. Two methods of resolving this indeterminacy are then explored: money illusion and a Taylor rule for monetary policy, a key feature of new consensus models. The paper concludes that endogenous money has negative implications for the behaviour and interpretation of neoclassical and new consensus models.     

MODELS OF COMPETITION BETWEEN FIRMS: ENDOGENOUS MARKET STRUCTURE IN THE KALECKIAN MODEL

The purpose of this paper is to incorporate free entry into the Kaleckian model. To this end, we consider a model with monopolistic competition, mark‐up pricing and a free‐entry condition. Using this model, the Kaleckian model is unstable under a wage‐led growth regime, and it is stable under a profit‐led growth regime, when the interest rate is supposed to be constant. Stability under a wage‐led growth can be achieved if the interest rate is allowed to respond positively to capacity utilization. We also find that a goods market policy, but not an income distribution policy, is then effective from an economic growth perspective.     

COMPETING VIEWS OF THE MONEY SUPPLY PROCESS: THEORY AND EVIDENCE

This paper examines three competing approaches to the determination of the money supply. The first approach is labelled the pure portfolio approach, and corresponds to the orthodox approach to the money supply. The second approach is labelled the pure loan demand approach, and corresponds to the Post Keynesian accommodationist view of endogenous money. The third approach is labelled the mixed portfolio-loan demand approach, and corresponds to the Post Keynesian structuralist view of endogenous money. The critical theoretical difference between the latter two models is identified in terms of the importance of the private initiatives of banks in accommodating expansions of loan demand. The paper then provides Granger-causality evidence on the three approaches, and concludes in favor of the mixed portfolio-loan demand approach.     

A NONLINEAR MODEL OF THE BUSINESS CYCLE WITH MONEY AND FINANCE (*)

In this paper we analyze the working of a capitalist system with sophisticated financial institutions, where the Modigliani-Miller theorem does not apply, so that the financial part of the economy affects the working of the real side. This model, in which the real and the financial sectors are connected throught a simple portfolio approach, and where the ratio between cash flow and debt commitment affects the pace of investment, explains the emergence of instability and, more generally, the cyclical behavior of the economy as an internally generated phenomenon of a capitalist system. As far as the dynamic behavior of the model is concerned, we can envisage the following process: when investment activity is low, the system evolves toward a stationary state; as soon as the accumulation rate starts growing, the model shows the existence of limited cycles and, when the elasticity of investment to internal finance increases further, a chaotic dynamic appears. Finally, we expect a situation of financial crisis to emerge when the elasticity of investment to internal financing constraint goes beyond a certain level, i.e. when the realized flow of profits is not sufficiently high to validate the debt commitments. The working of the model is referred to an economics with no technical change, while its dynamic properties will be investigated by the use of numerical simulation.     

ENDOGENOUS QUALITY CHOICE AND THE IMPACT OF QUANTITATIVE RESTRICTIONS

In this article a model of vertical product differentiation with two firms (a home firm and a foreign firm) engaged in endogenous quality competition. The firms engage in a two-stage game, where in the first stage they choose qualities in a sequential manner. In the second stage, the firms compete in quantities (a la Cournot) moving sequentially again. In the second part of this article, the impact of quantitative restrictions (ike a VER or quota) on the quality choices and other related variables like prices, firm profitability, consumer surplus, etc.

A MODEL OF INTERACTION BETWEEN THE VIRTUAL AND THE REAL ECONOMY

This paper demonstrates through a formal model how the wealth effect created by a stock market boom leads to the expansion of demand and output mostly through debt‐financed private consumption. However, inherent in this expansion is the threat of a subsequent contraction caused by the rising burden of servicing debt and falling creditworthiness. The formal analysis captures more precisely these conditions; it shows that, even in the medium run, the growth rates of the wealth in the stock market and of the real economy may move in opposite directions.     

A MODEL OF THE FIRM'S DEMAND FOR MONEY UNDER UNCERTAINTY

Recently, economists have centered their explanation of the demand for money balances on the transactions motive. The roles of precautionary and speculative motives remain ambiguous. The purpose of this paper is to fill this void. We develop a static model of the individual firm's demand for money in which prices and the interest rate are assumed to be random variables. In this model, the entrepreneur must decide his money holdings ex ante, and both capital and labor inputs are determined ex post. The demand for money corresponding to the various motives is a consequence of analyzing the ex ante profit function. Implications for monetary policy are derived from this analysis.

ON THE EXISTENCE OF THE ENDOGENOUS MORTGAGE RATE PROCESS

The mortgage rate is a major factor in the refinancing decision. The refinancing behavior influences cash flow and, therefore, mortgage price. The prices of mortgage instruments drives the mortgage rates. We consider a problem of the existence of a dynamic mortgage rate process which resolves this circular dependence. The existence is proved by constructing a solution using a newly proposed level set method.     

THE INTELLECTUAL FOUNDATION OF THE JOURNAL OF BUSINESS LOGISTICS AND ITS EVOLUTION BETWEEN 1978 AND 2007

Many logistics and supply chain management researchers have so far studied the nature of logistics and supply chain management research in terms of its domain and scope, its epistemological assumptions, and its evolution. However, the knowledge repository on which the scientific research community draws, that is, its intellectual foundation, has not yet been studied. Studying the intellectual foundation of research provides an unbiased and comprehensive picture of the development, dissemination, and utilization of its knowledge. In this article, we identify the most contributive works—in terms of citations received—that have been used in 497 articles published in the Journal of Business Logistics (JBL) between 1978 and 2007. By means of citation and co‐citation analysis, the intellectual structure of research in JBL is revealed and transformations therein are explored. Overall, the most frequently‐cited literature can be classified into six themes: physical distribution; inventory models; customer service; interorganizational relationships; competitive strategy; and empirical methodologies for socio‐scientific research. Furthermore, we determined a development in citation frequencies to these themes: literature related to physical distribution and inventory management declined over the three decades under study, whereas literature related to competitive strategy and empirical methods gained in importance. This development indicates a shift from an operational focus to a prioritization of managerial issues. Moreover, our results demonstrate a shift towards more relational and institutional research in logistics (management), which has been typically linked with the notion of supply chain management since the 1990's.     

THE LABOUR MARKET AND TECHNICAL CHANGE IN ENDOGENOUS CYCLES

The paper examines how a macro model, where there is an endogenous technical progress and strong interdependence between real and monetary aspects in both the labour and capital markets, can generate endogenous business cycles. This approach helps to understand the ambiguity of the NAIRU, the nature of the Phillips curve and the impact of labour productivity changes on the curve itself. Finally, the presence of expectation functions based upon a Markov‐switching time series process fosters endogenous dynamics and contributes to make asymmetries an important feature of the cycles.
