Demand, Production, and the Determinants of Distribution: A Caveat on "Wage-Led Growth"

The incomes of workers and capitalists pertain to different moments of accumulation. Wages are shares of capital outlays sustaining production; profits are shares of commodity sales. If aggregate demand and the scale of productive undertakings are shaped with a measure of mutual autonomy, the class distribution of income and the measure of economic activity are jointly determined by the same processes. In those settings “wage-led growth” has neither analytical nor policy purchase as associations between wage shares and levels of output (or growth) are confounded consequences of distinct effects on each measure of broader developments in the economy. A more appropriate dichotomy is that between “investment-led” and “consumption-led” growth, with the former resulting in comparatively higher wage shares. After advancing and illustrating these points, this paper motivates its approach to class income flows and the role of demand--which draw on the Circuit of Capital--in relation to the equivalent Kaleckian approaches sustaining arguments for “wage-led growth”

Credit, Profitability and Instability: A Strictly Structural Approach

This paper offers a purely structural characterisation of the content, limits and contradictions of credit relations in capitalist accumulation. Considering steady-state evolutions and step-change perturbations in a dynamic model of the Marxian circuit of capital, it establishes that sustained paces of net credit extension may boost aggregate profitability, the rate of accumulation, and the aggregate financial robustness of capitalist enterprises. These gains are limited by the economy’s dynamic productive capacities, and tempered by the risks of credit and monetary disruptions created payment obligations established by credit. Economies with higher paces of net credit extension are shown to be more vulnerable to the disruptions to accumulation variously emphasised by Marxian, Keynesian and Post-Keynesian contributions.

A completeness-like relation for Bessel functions

Completeness relations are associated through Mercer's theorem to complete orthonormal basis of square integrable functions, and prescribe how a Dirac delta function can be decomposed into basis of eigenfunctions of a Sturm-Liouville problem. We use Gegenbauer's addition theorem to prove a relation very close to a completeness relation, but for a set of Bessel functions not known to form a complete basis in $L^2[0, 1]$
