This paper presents a methodological discussion of two recent “endogeneity” critiques of the Kaleckian model and the concept of distribution-led growth. From a neo-Keynesian perspective, and following Kaldor (1955) and Robinson (1956), the model is criticized because it treats distribution as quasi-exogenous, while in Skott (2016) distribution is viewed as endogenously determined by a series of (exogenous) institutional factors and social norms, and therefore one should focus on these instead of the functional distribution of income per se. The paper discusses how abstraction is used in science and economics, and employs the criteria proposed by Lawson (1989) for what constitutes an appropriate abstraction. Based on this discussion, it concludes that the criticisms are not valid, although the issues raised by Skott provide some interesting directions for future work within the Kaleckian framework.

This paper contributes to the debate on income growth and distribution from a nonmainstream perspective. It looks, in particular, at the role that the degree of capacity utilization plays in the process of growth of an economy that is not perfectly competitive. The distinctive feature of the model presented in the paper is the hypothesis that the rate of capital depreciation is an increasing function of the degree of capacity utilization. This hypothesis implies analytical results that differ somewhat from those yielded by other Kaleckian models. Our model shows that, in a number of cases, the process of growth can be profit-led rather than wage-led. The model also determines the value to which the degree of capacity utilization converges in the long run.

In our era of global finance, the theory of aggregate demand management is alive and unwell, says Amit Bhaduri. In this policy brief, Bhaduri describes what he regards as a prevalent contemporary approach to demand management. Detached from its Keynesian roots, this “vulgar” version of demand management theory is being used to justify policies that stand in stark contrast to those prescribed by the original Keynesian model. Rising asset prices and private-debt-fueled consumption play the starring roles, while fiscal policy retreats into the background.

Returning to foundations laid down by Keynes and Kalecki, Bhaduri sets out to clarify whether there is any place for traditional demand management policies—featuring an active role for deficit spending and public investment—in the context of financial globalization. His conclusion: such policies are ultimately unavoidable if we are to revitalize the real economy and achieve stability. 

The Limits to Neo-Kaleckian Models and a Kaldorian Proposal

We argue that a fundamental difference between Post-Keynesian approaches to economic growth lies in their treatment of investment. Kaleckian-Robinsonian models postulate an investment function dependent on the accelerator and profitability. Some of these models rely on the importance of profitability, captured by the profit share, to make the case for profit-led growth. For their part, Kaldorian models place the emphasis on the accelerator. More important, investment is a derived demand; that is, it is ruled by the adjustment of capacity to exogenous demand, which, in turn, determines the normal level of capacity utilization.

In our view, the Kaldorian approach is better equipped to deal with some of the issues relating income distribution to accumulation with effective demand in the long run. We develop a Kaldorian open-economy model to examine the conditions under which an increase in real wages can produce profit or wage-led growth, showing that the limit to a wage-led expansion is a binding external constraint. The role and limitations of wages as a determinant of growth are further examined through spectral techniques and cycle analysis for a subset of developed economies. The evidence indicates that real wages are positively related to growth, investment, and capacity utilization. It also highlights the role of finance in sustaining expansions, suggesting that debt-led growth should not be identified with profit-led growth.

A Theoretical and Empirical Discussion of the Kaleckian Model of Growth and Distribution

This paper examines the “utilization controversy” around the Kaleckian model of growth and distribution. We show that the Federal Reserve data on capacity utilization, which have been used by both sides of this debate, are the wrong kind of data for the issue under examination. Instead, a more appropriate measurement can be derived from the data on the Average Workweek of Capital. We argue that the long-run dynamic adjustment proposed by Kaleckian scholars lacks a coherent economic rationale, and provide an alternative path toward the endogeneity of the desired utilization at the micro and macro levels. Finally, we examine the proposed adjustment mechanism econometrically. Our results verify the endogeneity of the normal utilization rate.

This paper examines the endogeneity (or lack thereof) of the rate of capacity utilization in the long run at the firm level. We provide economic justification for the adjustment of the desired rate of utilization toward the actual rate on behalf of a cost-minimizing firm after examining the factors that determine the utilization of resources. The cost-minimizing firm has an incentive to increase the utilization of its capital if the rate of the returns to scale decreases as its production increases. The theory of economies of scale provides justification for this kind of behavior. In this manner, the desired rate of utilization becomes endogenous.

Recently, some have wondered whether a fiscal stimulus plan could reduce the government’s budget deficit. Many also worry that fiscal austerity plans will only bring higher deficits. Issues of this kind involve endogenous changes in tax revenues that occur when output, real wages, and other variables are affected by changes in policy. Few would disagree that various paradoxes of austerity or stimulus might be relevant, but such issues can be clarified a great deal with the help of a complete heterodox model.

In light of recent world events, this paper seeks to improve our understanding of the dynamics of fiscal policy and financial crises within the context of two-dimensional (2D) and five-dimensional heterodox models. The nonlinear version of the 2D model incorporates curvilinear functions for investment and consumption out of unearned income. To bring in fiscal policy, I make use of a rule with either (1) dual targets of capacity utilization and public production, or (2) a balanced-budget target. Next, I add discrete jumps and policy-regime switches to the model in order to tell a story of a financial crisis followed by a move to fiscal austerity. Then, I return to the earlier model and add three more variables and equations: (1) I model the size of the private- and public-sector labor forces using a constant growth rate and account for their social reproduction by introducing an unemployment-insurance scheme; and (2) I make the markup endogenous, allowing its rate of change to depend, in a possibly nonlinear way, on capacity utilization, the real wage relative to a fixed norm, the employment rate, profitability, and the business sector’s desired capital-stock growth rate. In the conclusion, I comment on the implications of my results for various policy issues.

An Augmented Minskyan-Kaleckian Model

This paper augments the basic Post-Keynesian markup model to examine the effects of different fiscal policies on prices and income distribution. This is an approach à la Hyman P. Minsky, who argued that in the modern era, government is both “a blessing and a curse,” since it stabilizes profits and output by imparting an inflationary bias to the economy, but without stabilizing the economy at or near full employment. To build on these insights, the paper considers several distinct functions of government: 1) government as an income provider, 2) as an employer, and 3) as a buyer of goods and services. The inflationary and distributional effects of each of these fiscal policies differ considerably. First, the paper examines the effects of income transfers to individuals and firms (in the form of unemployment insurance and investment subsidies, respectively). Next, it considers government as an employer of workers (direct job creation) and as a buyer of goods and services (indirect job creation). Finally, it modifies the basic theoretical model to incorporate fiscal policy à laMinsky and John Maynard Keynes, where the government ensures full employment through direct job creation of all of the unemployed unable to find private sector work, irrespective of the phase of the business cycle. The paper specifically models Minsky’s proposal for government as the employer of last resort (ELR), but the findings would apply to any universal direct job creation plan of similar design. The paper derives a fundamental price equation for a full-employment economy with government. The model presents a “price rule” for government spending that ensures that the ELR is not a source of inflation. Indeed, the fundamental equation illustrates that in the presence of such a price rule, at full employment inflationary effects are observed from sources other thanthe public sector employment program.
