Conflict,growth, distribution,and employment: a long-run Kaleckian model

This paper presents a Kaleckian growth model in which (i) the rate of capacity utilization, the profit share, and the rate of employment are adjusted in the medium run, and (ii) the normal rate of capacity utilization and the expected rate of capital accumulation are adjusted in the long run. The long-run equilibrium is a continuum of equilibria and is characterized by hysteresis in that the long-run position of the economy depends on where it starts. An increase in the bargaining power of workers lowers the rate of unemployment in both the medium-run and the long-run equilibrium.     

Fiscal policy,government debt,and economic growth in the Kaleckian model of growth and distribution

This article presents the Kaleckian model of growth and distribution that sets a budget deficit ratio as an indicator of fiscal policy and examines the short- and long-run effects of an increase in budget deficits and a rise in income tax rates on the economy. The key short-run outcomes are as follows. First, expanded budget deficits have a positive effect on the rate of capacity utilization. Second, the tax rate for wage income does not affect the rate of capacity utilization, whereas the tax rate for capital income has a favorable impact on it. This result implies that raising the tax rate for capital income can be an important policy instrument for stimulating the economy. Third, we find that the economy exhibits a wage-led aggregate demand in the short run. The main long-run results are as follows. First, the effect of expanded budget deficits on the growth rate is ambiguous, since a higher debt burden negatively influences the rate of capacity utilization and hence economic growth, despite the increase in demand caused by government borrowing. A higher budget deficit ratio thus raises the growth rate only if a certain condition is satisfied. Second, the tax rate for capital income has a positive impact on the growth rate. Third, the economy shows a wage-led growth in the long run.     

Bargaining power, effective demand and technical progress: a Kaleckian model of growth

Following the Kaleckian tradition, this paper presents a demand-ledgrowth model in which the distribution of income is fully endogenised.This is done by introducing claims on income by workers andfirms. The bargaining power of these two groups affects, throughdistribution, the patterns of accumulation and inflation. Inturn, the bargaining power of workers is affected by the rateof change of employment. The paper discusses the model's static and dynamic implications,including the effects of exogenous and induced technical progress.The model confirms all the typical Kaleckian results, includingthe fact that increases in real wages may lead to acceleratingaccumulation as well as inflation. It also produces a new result:it is possible that an increase in the rate of change of labourproductivity may not lead to an increase in the rate of changeof employment.     

Income and wealth distribution in a simple model of growth

Summary. This paper studies a deterministic one-sector growth model with a constant returns to scale production function and endogenous labor supply. It is shown that the distribution of capital among the agents has an effect on the level of per-capita output. There exists a continuum of stationary equilibria with different levels of per-capita output. If the elasticity of intertemporal substitution is large, a higher output level can be achieved when income inequality is great, that is, when the income distribution is strongly dispersed. If the elasticity of intertemporal substitution is low, the reverse relation holds. The paper shows that countries with identical production technologies and identical preferences may have different GDP levels because wealth is distributed differently among their inhabitants.

Sources of energy productivity growth and its distribution dynamics in China

The purposes of this paper are to determine the sources of energy productivity growth at the provincial level in China and to examine the relative contributions of the sources and their impacts on regional inequality. Energy productivity change is first decomposed into five components attributable to changes in capital–energy ratio, labor–energy ratio, output structure, and technical efficiency change and technological change. Then a nonparametric analysis is implemented to statistically test the relative contributions of the components and their roles in the distribution dynamics of energy productivity. It is found that (1) changes in capital–energy ratio, output structure, and technological change contribute to energy productivity growth in China, (2) increase in capital–energy ratio caused by capital accumulation is the primary driving force for energy productivity growth, and (3) capital accumulation contributes to energy productivity convergence between Chinese provinces over the time period of 1990–2005.     

TFP growth and its determinants: a model averaging approach

Total Factor Productivity (TFP) accounts for a sizable proportion of the income differences across countries. Two challenges remain to researchers aiming to explain these differences: on the one hand, TFP growth is hard to measure empirically; on the other hand, model uncertainty hampers consensus on its key determinants. This paper combines a non-parametric measure of TFP growth with Bayesian model averaging techniques in order to address both issues. Our empirical findings suggest that the most robust TFP growth determinants are time-invariant unobserved heterogeneity and trade openness. We also investigate the main determinants of two TFP components: efficiency change (i.e., catching up) and technological progress.     

Kaleckian Effective Demand and Sraffian Normal Prices: Towards a reconciliation

Sraffians and Kaleckians alike reject the belief that higher rates of accumulation need be associated with lower real wage rates or higher propensities to save. The rejection of this proposition is mainly based on the endogeneity of the rate of capacity utilization, both in the short and the long run. This endogeneity often relies on a discrepancy between the realized and the normal rates of profit, or between the realized and the target rate of capacity utilization, a discrepancy which some authors believe is unwarranted in long run analysis. Various models that eliminate this divergence are outlined. In all these models, the normal rate of profit itself is taken as an endogenous variable. In the first two models, the normal rate of profit depends either on the realized profit rate or the rate of interest. Supply-led results may then reappear in long run analysis. In the last model, one introduces the possibility of a divergence between the rate of return as assessed and targeted by firms, and the rate of return that is actually incorporated into prices. This divergence arises because of the bargaining power of workers and their real wage resistance. Under these conditions, the demand-led results of the Kaleckian tradition are recovered in a model with definite solutions.     

Endogenous growth and income distribution

A theory of endogenous growth is based on an investment possibility function, relating the growth rate of output to the ratio of gross investment to output and the growth rate of employment as formulated originally by M. F. Scott. Consumers maximize an intertemporal utility function and producers maximize the value of the firm. The long-run rate of growth depends on consumer preferences, the exogenous growth of labor supply and the tax rate on output. The functional distribution of income is determined along with the investment ratio in the steady state. Labor market imperfections and real wage inertia induce transition processes, which are relevant for medium term growth.We are indebted to Olivier Blanchard, Casper van Ewijk, Frederick van der Ploeg, Anton van Schaik, Maurice Scott, Jacques Smulders, and two anonymous referees for their valuable comments on an earlier version.

Energy distribution and economic growth

This research examines the physical constraints on the growth process. In order to run, maintain and build capital energy is required to be distributed to geographically dispersed sites where investments are deemed profitable. We capture this aspect of physical reality by a network theory of electricity distribution. The model leads to a supply relation according to which feasible electricity consumption per capita rises with the size of the economy, as measured by capital per capita. Specifically, the relation is a simple power law with an exponent assigned to capital that is bounded between 1/2 and 3/4, depending on the efficiency of the network. Together with an energy conservation equation, capturing instantaneous aggregate demand for electricity, we are able to provide a metabolic-energetic founded law of motion for capital per capita that is mathematically isomorphic to the one emanating from the Solow growth model. Using data for the 50 US states 1960–2000, we examine the determination of growth in electricity consumption per capita and test the model structurally. The model fits the data well. The exponent in the power law connecting capital and electricity is 2/3.     

Technology, demand and distribution: a cumulative growth model with an application to the Dutch productivity growth slowdown

This paper argues that the case for real wage growth restraint,and the consequent restoration of profitability, which the mainstreamconsensus regards as a necessary condition for sustained outputand productivity growth, is based on weak foundations, becauseit neglects the negative impact of wage moderation on productivitygrowth. Using a general Keynesian growth model, which integratesa (wage-led or profit-led) demand regime and a productivityregime (incorporating the productivity-growth enhancing effectsof higher demand and higher real wages), the conditions areidentified under which real wage restraint fails to raise outputand productivity growth. The model is applied empirically tothe Netherlands (1960–2000).     

The normal distribution as a model of technological substitution

A model for forecasting technological substitution, based on the use of the normal distribution, is presented. Both mathematical and graphical techniques are discussed. Examples from the literature are used to illustrate the model.     

The ramsey model revisited: The optimality of cyclical consumption and growth

This paper reconsiders the familiar Ramsey model of optimal saving. This model is modified with two respects: direct spillovers (positive or negative) of capital on utility and penalties for changes of consumption. It will be shown that these two modifications may substantially change the stability properties of an optimal programme if capital provides utility directly (in addition to indirectly through production). More precisely, complex strategies such as (stable) limit cycles or even unstable policies may be optimal. Adjustment costs must be sufficiently high in order to obtain stable limit cycles (or even exploding spirals). This is quite surprising because large adjustment costs are expected to smooth intertemporal strategies.     

The early reactions to Value and capital: critics,critiques and correspondence in comparative perspective

The reception of Hick's Value and capitalis not as well documented as other important economics books of that period. In this article I shall analysis the main reviews of Value and capitalwith special emphasis on the critial reviews. Reference will be made to Hick's unpublished correspondence with Hawtrey, Kaldor and Robertson. Finally a consideration of the important issues of communicabilityand relevance will be undertaken.     

The engine of growth or its handmaiden?

This paper presents an analysis of time-series data for the countries in the Summers-Heston (1991) data set, in an attempt to ascertain the evidence for or against the export-led growth hypothesis. We find that standard methods of detecting export-led growth using Granger-causality tests may give misleading results if imports are not included in the system being analyzed. For this reason, our main statistical tool is the measure of conditional linear feedback developed by Geweke (1984), which allows us to examine the relationship between export growth and income growth while controlling for the growth of imports. These measures have two additional features which make them attractive for our work. First, they go beyond meredetection of evidence for export-led growth, to provide a measurement of itsstrength. Second, they enable us to determine the temporal pattern of the response of income to exports. In some cases export-led growth is a long-run phenomenon, in the sense that export promotion strategies adopted today have their strongest effect after eight to 16 years. In other cases the opposite is true; exports have their greatest influence in the short run (less than four years). We find modest support for the export-led growth hypothesis, if “support” is taken to mean a unidirectional causal ordering. Conditional on import growth, we find a causal ordering from export growth to income growth in 30 of the 126 countries analyzed; 25 have the reverse ordering. Using a weaker notion of “support”—stronger conditional feedback from exports to income than vice versa, 65 of the 126 countries support the export-led growth hypothesis, although the difference in strength is small. Finally, we find that for the “Asian Tiger” countries of the Pacific Rim, the relationship between export growth and output growth becomes clearer when conditioned on human capital and investment growth as well as import growth.     

Migration,growth, distribution and welfare

In this note we argue that the inverted U curve of inequality is a technical derivative of the attributes of the conventional indices of inequality; that these indices are inadequate measures of the change in welfare associated with the typical distributional consequences of rural-to-urban migration; and that an explicit welfare judgment with respect to this process should and can be made.     

Human capital distribution, growth and convergence

This paper studies the dynamic relationship between distribution and endogenous growth in an overlapping generations model with accumulation of human and physical capital. It is shown how human capital can determine a relationship between per capita growth rates and inequality in the distribution of income. Family background effects and spillovers in the transmission of human capital generate dynamics in which aggregate variables depend not only on the stock, but also on the distribution of human capital. The evolution of this distribution over time is then characterized under different assumptions on private returns and the form of the externality in the technology for human capital. Conditions for existence, uniqueness and stability of a constant growth equilibrium with a stationary distribution are derived. Increasing returns, idiosyncratic abilities and the possibility of poverty traps are explicitely characterized in a closed form solution of the equilibrium dynamics, showing the role played by technology and preferences parameters.
