Was Ireland's Celtic Tiger Period Profit-led or Wage-led?

This paper examines the macroeconomic performance of the Irish economy in the years leading up to the Celtic Tiger period and afterward, from 1980 to 2011. The goal of the paper is to determine how a severe recession in the 1980s could be followed so quickly by the unprecedented boom years of the Celtic Tiger, and followed again by the marked economic downturn since 2007. I build a Keynesian model of growth that integrates effective demand and productivity regimes to allow for the possibility that a redistribution of income can either spur or retard growth, depending on whether the regime is wage-led or profit-led. Using data for the Irish economy I test this model for wage-led or profit-led growth, finding plausible evidence that the Celtic Tiger years were, in fact, profit led.     

Household Debt,Dynamic Stability,and Change in Demand Creation Patterns

This paper examines dynamic stability and demand creation patterns of an economy in the context of the augmentation of household debt. First, we investigate the dynamic characteristics specific to an economy with household borrowing. Second, we reveal how demand creation and economic growth pattern change with the introduction of households' active borrowing. Our results shows that it is more favorable for the stability of an economy to politically control the interest rate on lending rather than to leave it to be determined by private financial institutions. Our results also indicate that even if the demand regime is wage-led, paradoxically, a rise in wage share may not necessarily stimulate economic growth. On the other hand, profit-led growth is more likely.     

Distribution and growth reconsidered: empirical results for six OECD countries

We analyse the relationship between functional income distributionand economic growth in Austria, France, Germany, the Netherlands,the UK and the USA from 1960 until 2005. The analysis is basedon a demand-driven distribution and growth model for an openeconomy inspired by Bhaduri and Marglin, which allows for eitherprofit- or wage-led growth. We find that growth in France, Germany,the UK and the USA has been wage-led, whereas Austria and theNetherlands have been profit-led. In the case of Austria a domesticallywage-led economy changes to profit-led when including the effectof distribution on external trade. The Netherlands, however,are already profit-led without external trade. Our results sofar only partially confirm Bhaduri and Marglin's theoreticalconclusion that wage-led growth becomes less feasible when theeffects of distribution on foreign trade are taken into account.     

Demand regimes and income distribution reconsidered in an open economy portfolio balance framework

A large body of neo-Kaleckian literature has debated the distributional determinants of demand and growth. One general conclusion has been that open economy considerations weaken the potential for a wage-led growth regime. However, this literature has largely ignored asset portfolio considerations and the stock and flow interactions that result from the feedback from savings to wealth and from wealth to the current account. This study develops a theoretical framework that specifies a fuller system of (instantaneous) flow equilibria embedded in a medium-run framework with stable steady-state stocks of real and financial assets. The balance-of-payments constraint that results ensures that simply raising the wage does not yield a higher stock of real capital. A lower markup may increase the steady-state stock of capital but only through the relative price channel. These results are much stronger than those derived in the existing literature, and more important, emerge regardless of whether the demand regime is wage-led or profit-led in the absence of international trade.     

Productivity,real exchange rate,and aggregate demand: An empirical exercise applied to Brazil from 1960 to 2011

This research analyzes, from a post Kaleckian perspective, the interactions among the aggregate demand, the real exchange rate, productivity, and real wages in the Brazilian economy from 1960 to 2011. It adopts the longstanding perspective that demand is the driver of capital accumulation and economic growth. The research comprises the following steps: (a) a critical assessment of the growth regime literature, with a particular emphasis on issues related to productivity and the real exchange rate; (b) understanding the relationship between the real exchange rate and the productivity and growth regimes; (c) proposing a theoretical model that relates the real exchange rate, productivity, and the growth regime; and (d) an empirical test of the interaction between the real exchange rate, productivity, and the growth regime. Theoretically the study develops a model showing the interactions between the aggregate demand, the real exchange rate, productivity, and real wages. Furthermore, this research attempts to address the lack of theoretical and empirical studies about the relationship between the aggregate demand, the real exchange rate, productivity and real wages.     

An empirical test of the Post-Keynesian growth model applied to functional income distribution and the growth regime in Brazil

The main purpose of this paper is to empirically investigate whether, between 1970 and 2008, the Brazilian economy was profit-led or wage-led. To this end, we approach a canonical post-Keynesian growth model (PKGM) to estimate certain vector autoregressive (VAR) models and perform Granger non-causality tests. Three main results are extracted from the generalized impulse-response functions provided by the VAR models. First, a positive profit-share innovation affects economic growth and capacity utilization rate, both in the same direction, suggesting a profit-led pattern. Second, a profit share shock positively affects both the ratio actual/potential output, and capital accumulation, reinforcing the previous result. Third, a capacity utilization shock is shown to positively affect both output growth and capital accumulation via the accelerator effect. On the one hand, the pairwise Granger non-causality test does not provide any evidence of causality running from profit share to economic growth or capacity utilization. On the other hand, there is some evidence of Granger causality running from profit share to capital accumulation.     

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).     

Is the long-run equilibrium wage-led or profit-led? A Kaleckian approach

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 growth are adjusted in the long run. Both the Kalecki-type and the Marglin–Bhaduri-type investment functions are introduced. Using the model, we examine which regime is obtained in the long-run equilibrium, the wage-led growth regime or the profit-led growth regime.     

Functional distribution of income,aggregate demand,and economic growth in the Chinese economy, 1978–2007

This paper seeks to analyse the relationship between the functional distribution of income, aggregate demand and growth in the Chinese reform economy. For this purpose, the Bhaduri-Marglin Model is used to indicate the theoretical possibility of both profit-led and wage-led growth regimes. Previously, the principal literature on the evolution of factor shares in China was reviewed. The statistical series for the period 1978–2007 are reconstructed to carry out our analysis of the relations between capital share and investment, on one hand, and labour share and consumption, on the other. Supported by empirical analysis and the model estimations, it is argued that Chinese growth has been profit-driven. Finally, the implications are presented concerning Chinese economic prospects.     

Stagnation or transformation of a dual economy through endogenous productivity growth

A growth model is developed for an open dual economy. The economyexpands owing to a higher growth rate of labour productivityin the modern sector through the Kaldor–Verdoorn channeland higher effective demand through a Keynesian channel. Themodel incorporates a retardation mechanism affecting the slopesof productivity and output growth schedules as labour surplusand economies of scale diminish. A wage-led or profit-led regimeand initial conditions may give rise to: de-industrializationin terms of both output and employment; a growth trap sustaininga situation of structural heterogeneity; or sustainable employmentand adequate output and productivity growth.     

The North Will Rise Again: Pensions,Politics and Power in the 1980’s

I aim at contributing to the academic debate about the relationship between functional income distribution and economic growth in regard to the large and open economy of Turkey in the period from 1987 to 2006. To this end, I propose a simple post-Keynesian model, so as to test whether the Turkish economy is wage or profit-led. I find evidence that, while a rising wage has a positive effect on investment, it does not affect consumption in Turkey. Hence the combined effect of a rising wage share on domestic demand (investment plus consumption) is positive. However, since exports and imports are so sensitive to labor costs, as they are in the case of Turkey, the regime becomes profit-led.     

Endogenous technological change,income distribution,and unemployment with inter-class conflict

This paper presents a Kaleckian growth model that incorporates endogenous technological change. The model endogenously determines the rate of capacity utilization, the rate of economic growth, income distribution, and the employment rate in addition to technological change. The paper shows that whether or not an increase in the relative bargaining power of workers raises the long-run equilibrium unemployment rate depends on which regime is realized in the long-run equilibrium. If, for example, the long-run equilibrium corresponds to the wage-led growth regime, a rise in the relative bargaining power of workers leads to a decline in the unemployment rate. This result is never obtained from the mainstream NAIRU model.     

Some unpleasant currency-devaluation arithmetic in a post Keynesian macromodel

The conventional view argues that devaluation increases the price competitiveness of domestic goods, thus allowing the economy to achieve a higher level of economic activity. However, these theoretical treatments largely neglect two important effects following devaluation: (1) the inflationary impact on the price of imported intermediate inputs, which raises the prime costs of firms and deteriorates partially or totally their price competitiveness; and (2) the redistribution of income from wages to profits, which ambiguously affects the aggregate demand as workers and capitalists have different propensities to save. New structuralist economists have explored these stylized facts neglected by the orthodox literature and, by and large, conclude that devaluation has contractionary effects on growth and positive effects on the external balance. Given that empirical evidence on the correlation between devaluation and growth is quite mixed, we develop a more general Keynesian–Kaleckian model that takes into account both opposing views in order to analyze the net impact of currency depreciation on the short-run growth rate and the current account. We demonstrate that this impact can go either way, depending on several conditions such as the type of growth regime, that is, wage-led or profit-led, and the degree of international price competitiveness of domestic goods.     

Cyclical growth in a Goodwin–Kalecki–Marx model

This paper presents a disequilibrium macrodynamic model that incorporates certain elements from Goodwin (the dynamics of the rate of employment and income distribution), Kalecki (an investment function independent of savings, and mark-up pricing in oligopolistic goods markets), and Marx (the reserve-army and reserve-army-creation effects). The model has a system of differential equations for the rate of utilization, profit share, and rate of employment. We show that there exist limit cycles that depend on the sizes of the reserve-army effect and reserve-army-creation effect. This implies that there exists a situation in which the economy experiences endogenous and perpetual growth cycles. Moreover, we show that if the stable long-run equilibrium corresponds to the profit-led growth regime, an increase in the bargaining power of workers increases the rate of unemployment; conversely, if the equilibrium corresponds to the wage-led growth-regime, an increase in the bargaining power of workers decreases the rate of unemployment.     

On wage- and profit-led demand regimes: learning from the evidence

Abstract

This paper contributes to the empirical research around the “wage-led” or “profit-led” demand regimes. It first reviews how Kalecki, and then Steindl, approached the relationship between economic growth and income distribution. Then, empirical analysis carried out under the probabilistic approach to econometric modeling shows statistical evidence, estimated through cointegration analysis, that in the long run, in three very open economies—Mexico, France, and Korea—the wage share is positively associated with demand and output. It finally discusses the macroeconomic dilemma that almost all countries have to face, i.e., a positive effect of a high-wage policy on demand and employment may diverge from a negative effect on output compatible with external equilibrium.     

Wage–price dynamics and income distribution in a semi-structural Keynes–Goodwin model

The paper studies the role of income distribution within a medium-scale macrodynamic model built in a Keynesian and Goodwinian tradition. Combining a wage and price Phillips curve, adjustments of an inflation climate, an IS relationship determining output, Okun’s law for employment and the Taylor rule for monetary policy, a semi-structural model is obtained that incorporates the most important macroeconomic channels in a closed economy. After assessing the reasonable time series variabilities in stochastic simulations, a deeper analysis is concerned with the stabilizing and destabilizing effects of the model’s parameters, and with a structural shift in income distribution. In many details of these investigations, the distinction between a wage-led and profit-led regime becomes important.     

Testing the demand regime hypothesis in the Euro Area. Evidence from a VAR approach

The article brings new evidence that intra Euro Area trade imbalances should be thought of as the outcome of the interaction of opposing growth strategies between northern/surplus countries (Austria, Belgium, Germany, Netherlands) and southern/deficit countries (France, Italy, Portugal, Spain). By using a vector autoregression model, econometric evidence clarifies that the demand regime in the southern region is wage-led, while profit-led in the northern region. Moreover, a downward-wage adjustment in the northern region (negative wage shock) contributed to increasing the intra-EA trade surplus vis-à-vis the southern region by far more than an upward-wage adjustment in the southern region (positive wage shock).     

On the short-run relationship between the income distribution-growth and debt-growth regimes

This paper examines the short-run relationship between the income distribution-growth and debt-growth regimes using a simple, post-Keynesian, demand-driven model. While mechanisms of wage-led and profit-led growth have been revealed, their relationship with debt-led and debt-burdened growth is yet to be clarified, because arguments on these growth regimes were developed separately. This paper shows that the growth regimes transform as the regime-switching parameters in the IS balance change. By way of theoretical analysis, this paper presents some important implications for (i) the possibility of the combination of growth regimes; (ii) the features of post-Keynesian economic analysis of income distribution, debt, and demand-led growth, which sharply contrast with the basic neo-classical theory; and (iii) theoretical validation of recent empirical results. Moreover, this paper also suggests some policy implications or lessons for the combination of economic growth regimes.     

Functional income distribution and aggregate demand in the Euro area

An increase in the wage share has contradictory effects on thesubaggregates of aggregate demand. Private consumption expendituresought to increase because wage incomes typically are associatedwith higher consumption propensities than capital incomes. Investmentexpenditures ought to be negatively affected because investmentwill positively depend on profits. Net exports will be negativelyaffected because an increase in the wage share corresponds toan increase in unit labour costs and thus a loss in competitiveness.Therefore, theoretically, aggregate demand can be either wage-ledor profit-led depending on how these effects add up. The resultswill crucially depend on how open the economy is internationally.The paper estimates a post-Kaleckian macro model incorporatingthese effects for the Euro area and finds that the Euro areais presently in a wage-led demand regime. Implications for wagepolicies are discussed.     

Overhead labour and feedback effects between capacity utilization and income distribution: estimations for the USA economy

ABSTRACT

Empirical studies on the USA have not reached a consensus on whether its demand is wage- or profit-led, leading many scholars to scrutinize what drives the empirical results. This article tests two possible explanations for profit-led results which are related to the presence of overhead labour. To do so, a vector autoregression model is estimated for the USA from 1964 to 2010 and the wage share is split between supervisors/managers and direct workers. The results support the argument that the income redistribution away from workers and towards managers increased the likelihood of profit-led demand and suggest that an increase in the workers’ share of income would stimulate the economy. Also, increases in capacity utilization negatively affect the supervisors’ share, so that short-run profit-led results may be capturing the cyclical behaviour of the profit share, but the effect becomes positive as time goes by, suggesting a complex determination of functional income distribution, as capacity utilization affects it in ambiguous ways.
