Hidden links in the warranted rate of growth: the supermultiplier way out

Post Keynesian models consider growth to be demand-led – a logical consequence of Keynes's principle of effective demand. After Harrod's seminal paper in 1939 Harrod, R. F. 1939. An essay in dynamic theory. Economic journal, 49, 14–33.[Crossref], [Web of Science ®] , [Google Scholar] they try to unearth the hidden variables that might allow the adaptation of the warranted rate, determined from the supply side, to demand-growth expectations that supposedly have an autonomous source. The purpose of this paper is to show that an investment function based on the accelerator and integrated in a supermultiplier is able to shape the warranted rate in consonance with the autonomous trend. The supermultiplier reveals itself as a stable and stabilising mechanism when demand is split into permanent and transient. Hopefully the paper will build bridges with other Keynesian, Kaleckian and Sraffian strands that have so far dismissed the supermultiplier solution because of its apparently inherent instability.     

Interest rate policy,effective demand,and growth in LDCs

Orthodox criticisms of ‘financial repression’ in LDCs argue that interest rate liberalization promotes investment and economic growth by increasing the supply of bank credit and improving the efficiency of credit allocation. The present paper develops a Kaleckian model in which increases in deposit interest rates may lower investment and growth by placing downward pressure on effective demand – even if interest rate liberalization results in decreased borrowing costs. The focus of the Kaleckian model on effective demand issues is then contrasted with prior criticisms of the proliberalization view. Finally, the relevance of the Kaleckian approach is demonstrated in connection with the important role of effective demand and distributional effects in the failure of the Chilean financial liberalization to promote a stable growth of output and investment.     

Variety,growth and demand

A dynamic model of demand compatible with a changing composition of the economic system is presented in this paper. Consumers are not expected to have completely formed preferences for radically new objects of consumption. Consumers adopt new goods or services ,created by innovation, only if three barriers are overcome: 1) a critical (minimum) level of income, 2) critical human capital, 3) critical fitness. However, even a new good or service with a fitness higher than that of pre-existing ones, will not be immediately adopted. Consumers'.limited knowledge will slow down the rate of adoption of any new good or service.     

Aggregate demand shocks and economic growth

The traditional view of growth and fluctuations implies that aggregate demand shocks result in only transitory departures from trend or “normal” output, which is determined exclusively by aggregate supply factors. Using a simple dynamic framework for a less-developed economy, a series of models is developed to show that aggregate demand can have a permanent effect on economic growth. It is shown that even if the economy converges to some “normal” path, this path itself may be altered by large demand shocks, due to increasing returns and hysteresis effects in labor markets and balance of payments constraints. It is also shown that the economy may not converge to its “normal” path, in which case fiscal and monetary policy will have long-term effects on output and growth.     

Estimating the interest rate semi-elasticity of the demand for money in low interest rate environments

We estimate the time profile of the interest rate semi-elasticity of the demand for money that is theoretically derived from a money-in-the-utility-function (MIUF) model. This semi-elasticity increases to infinity as interest rates fall to zero. Therefore, the use of this semi-elasticity has an advantage when examining the highly interest-elastic demand for money in low interest rate environments. Using Japanese and U.S. data, we find that the semi-elasticity increases exponentially in low interest rate environments. For example, the highest value of the semi-elasticity in Japan is observed in 2005, and is approximately 350 times larger than the value in 1990.     

Aggregate demand, food prices, and the underlying rate of inflation

With the inflation rate rising in the 1970s, the concept of an underlying rate of inflation became increasingly popular. The rationale for subtracting out food and fuel price increases was straightforward: such increases were viewed as reflecting special supply-side factors likely to be temporary and reversible or, at worst, one-time rises in relative prices with no lasting effect on the inflation rate. This paper presents empirical evidence that raises serious questions about these assumptions and procedures. More specifically, shifts in aggregate demand have a statistically significant cumulative effect on food prices and this effect increases quantitatively as food moves from the farm to the retail level. The cumulative effect of demand on food prices was also found to have increased over time (as farmers' value-added declined) and demand appears to effect prices more quickly at the wholesale level than at the retail level.     

The co-evolution of innovation,demand and growth

In order to explain long-run economic development, we analyse in this paper the interplay between supply-side and demand-side processes. On the supply side, three different innovation processes are observed and interact: (i) growing productive efficiency, (ii) the emergence of new sectors and (iii) the increasing quality and differentiation of existing products. On the demand side, we analyse the meaning of disposable income and varying preference systems. The analysis is undertaken with the help of a numerical model of economic growth by the emergence of new industries. Our results show that the time path of economic development which we observe could not have been generated by taking into account a supply-side-based view on innovations alone. Without making reference to the formation of an adequate demand, development processes cannot be explained. The three processes need to be combined because each one individually would not suffice to generate long-run economic development. However, only with the formation of an adequate demand long-run economic development becomes sustainable.     

A demand and supply analysis of productivity growth

The paper rejects growth accounting as failing to reveal the economic forces that drive growth. Instead, it seeks to explain changing productivity growth in terms of economic phenomena such as the changing structure of output, the rate of adoption of new technology, and the strength of aggregrate demand. We introduce such a model and test it using pooled cross section and time series data for 16 OECD economies over a 30 year period. The parameter estimates allow us to decompose each economy's productivity growth into the part caused by its changing structure and the part explained by demand conditions. The estimates are used to account for the productivity slowdown that occurred in these economies after 1973, and to examine the recent productivity increase in the US. The model fully explains this growth surge in terms of the changed demand factors and structure of the US economy. We conclude by arguing that a prime benefit of strong aggregate demand is its stimulation of investment and technological change, leading to the adoption of new technology on a broad front.     

A note on the implicit interest rate on demand deposits

This paper examines the significance of several estimated measures of the implicit interest rate on demand deposits in an annual demand-for-money function. The evidence demonstrates that the coefficient estimates of the implicit interest rate are not positive and statistically significant as predicted due to the scarcity of data points and the high collinearity with other opportunity cost variables.     

Exchange rate sensitivity of the demand for money in developing countries

There is consensus among researches that under the present floating exchange rate system although developing countries peg their exchange rate to a major currency, they cannot avoid fluctuation in their effective exchange rates as long as major currencies fluctuate against one another. Few authors have investigated the effects of changes in effective exchange rates of developing countries on their imports, exports, trade balance, demand for international reserves, inflation etc. In this paper we try to inestigate the effects of effective exchange rates of developing countries on their demand for money. Previous authors who have estimated a money demand function, inclusive of an exchange rate variable (bilateral or effective), have restricted themselves to industrial countries only. By using quarterly data over the 1973–85 period, it is shown that in most developing countries, while the short-run effcts of depreciation could be in either direction, its long-run effects are negative indicating that depreciation causes a decline in the demand for domestic currency.     

Effects of exchange rate flexibility on the demand for international reserves

We incorporate a measure of exchange rate flexibility into the standard reserve demand equation and present empirical results for the 1976–1985 period which are consistent with the work of Officer (1976) and Frenkel and Jovanovic (1981) indicating the existence of economies of scale and the demand for reserves.     

Exchange rate volatility and the demand for money in the U.S.

This paper examines the effect of changes in the level and volatility of exchange rates on the demand for money. It hypothesizes that exchange rate volatility exerts a negative influence on money demand separate from the effect of the level of exchange rates. Using U.S. data covering the period from 1974.1 to 1990.4, it is found that, regardless of whether the adjustment process is modeled as an error-correction or a partial-adjustment model, exchange rate volatility is negatively related to the demand for real M2 balances. This relationship is found to be more pronounced when exchange rates are expressed in real terms. The results imply that money demand responds to both the volatility of domestic prices relative to foreign prices and to the volatility of nominal exchange rates. Little evidence is found in support of the hypothesis that the level of exchange rates exerts a significant influence on money demand.     

An alternative demand indicator: the 'non-accelerating inflation rate of capacity utilization'

This article examines the usefulness of the NAIRCU, the ‘non-accelerating inflation rate of capacity utilization’ as a demand indicator of inflation for eight European countries. So far the NAIRCU has been estimated for the USA only, where it serves as a useful indicator for inflation. In most European countries, deviations from the equilibrium level of capacity utilization influence inflation significantly. Further, the results not only indicate that in more recent periods the NAIRCU has shifted upward, indicating higher efficiency of the production process, but also that confidence intervals have increased over time reducing the usefulness of the NAIRCU somewhat.     

The demand for money and the variability of the rate of inflation : An emperical note

In this note we incorporate the effect of inflation variability on the demand for money in Pakistan. It is found that this variable has a significant impact on money demand function. Our results are similar to those of Klein while they differ with Blejer.     

Learning to consume – A theory of wants and the growth of demand

The theory of economic growth takes little notice of what is happening on the demand side of the markets so that ever more goods and services can be sold. In order to make progress, this paper revives a classical notion in economics, the concept of wants, and re-casts it in terms of a behavioral theory. Hypotheses are discussed concerning the wants people pursue, the changes in these wants, and the corresponding consumption knowledge. The implications derived focus on why, in spite of the historically unique growth of per capita income in the modern economies, consumption has not been altogether satiated. In the suggested explanation, increasing variety of consumption items offered in the markets and increasing specialization of the consumers in their demand activities play a key role.     

On the relations between demand creation and growth in a monopolistic firm

This paper deals with the allocation of resources over time by a monopolistic firm between growth of the productive capacity and growth of the market-demand capacity. As the demand-creation relations follow an S-shaped curve, different phases in the behavior of the growing firm are conceived in which investment cycles occur both in productive and demand-creation activities.The paper analyzes the case of homogeneous resources as well as nonhomogeneous resources. It is shown that in general the phases in the behavior of the growing firm are preserved in both cases. In the homogeneous case, when there are investment activities in both types of capital, it is shown that the firm will allocate its resources between the two activities in such a way that the ratio of the rate of growth of demand price (with respect to demand-creation capital) and the rate of growth of output (with respect to productive capital) will be equal to one plus the reciprocal of the elasticity of demand and will, therefore, be bounded between zero and one.     

Asymmetric effects of exchange rate changes on the demand for money in Africa

In order to account for currency substitution, the exchange rate is included in the demand for money. More recent studies have demonstrated that exchange rate changes could have asymmetric effects on the demand for money or domestic currency. In this paper, we consider the experiences of 18 African countries and show that in most countries, indeed exchange rate changes have short-run asymmetric effects on the demand for money. However, short-run effects translate to long-run asymmetric effects only in a limited number of African countries.     

The recent growth of the internet and changes in household-level demand for entertainment

This paper investigates whether the recent growth of the Internet complements or substitutes for consumption of existing entertainment goods. Applying a difference-in-differences approach to the Consumer Expenditure Survey, I find varying degrees of potential substitutability between Internet growth and consumer expenditures across different entertainment goods. For most goods, these negative effects appear to be sensitive to changes in specifications. In contrast, the negative effect on recorded music expenditure is statistically significant and robust to different specifications.     

Asymmetric effects of exchange rate changes on the demand for money in China

In order to account for currency substitution, the majority of recent studies relating to the specification of the demand for money include the exchange rate as another determinant of the demand for money. However, those who have estimated the demand for money in China have been unable to find any significant effects of exchange rate changes on the demand for money by the Chinese. We show that this is due to the assumption that exchange rate changes have symmetric effects. Once depreciations are separated from appreciations of the yuan, those exchange rate changes are shown to have significant effects on the demand for money in China, but in an asymmetric manner.     

Innovation and growth: supply and demand factors in the recent US expansion

It is widely held that the social-economic context of the US,characterised by labour market flexibility and deregulationof product and capital markets, lies at the basis of the innovativecapacity displayed by the country's productive system in the1990s, thus accounting for the growth differential with Europe.Starting from a different interpretative model of innovationand growth, the paper focuses on both supply (institutionaland technological) and demand factors. It is argued that, whentheir interaction is taken into account, there is no strongevidence that more deregulated labour and product markets areamong the factors allowing for US growth. In accordance withthe view that there is no single road to innovation and growth,this leaves room for the exploration and implementation of policiesthat might reconcile innovation and growth with safeguards suchas those provided by Europe's social institutions.
