Effort Elicitation,Wage Differentials and Income Distribution in A Wage‐Led Growth Regime

Motivated by the empirical evidence on endogenous labor effort and wage differentials, this paper explores implications for distribution and growth of firms using different strategies to elicit effort from workers. The frequency distribution of effort‐elicitation strategies across firms is governed by a replicator dynamic that generates wage differential as a long‐run equilibrium. Although firms willing to elicit more effort have to compensate workers with a higher wage rate, a larger proportion of firms adopting such strategy will not necessarily produce a higher wage share and thereby a higher growth rate. The intuition is that, depending on the accompanying rise in labor productivity, the wage share may not vary positively with the proportion of firms paying higher wages.     

Demand‐led growth with endogenous innovation

This paper contributes to the recent macro‐dynamics literature on demand‐led growth, drawing upon the seminal idea that the implications of Harrodian instability may be tamed by a source of autonomous expenditure in the economy. Contrary to the other contributions in this literature, real autonomous expenditure is not growing at an exogenously given rate, and partly consists of a flow of profit‐seeking R&D and innovation expenditures raising labour productivity through time. If the state of distribution, hence the wage share, is exogenously fixed and constant, the model gives rise to dynamics in a two dimensional state space, that may converge to, or give rise to a limit cycle around, an endogenous growth path. An exogenous rise of the profit share exerts negative effects on long‐run growth and employment, showing that growth is wage led.     

Conspicuous Consumption,Inequality and Debt: The Nature of Consumption‐driven Profit‐led Regimes

This paper extends the theoretical concept of wage‐led and profit‐led demand regimes by incorporating relative consumption concerns. Specifically, it integrates the Veblenian concept of conspicuous consumption into the Bhaduri–Marglin model by assuming that relative consumption concerns matter primarily within the working class. If in such a framework the profit share increases and the corresponding decrease in workers' income is distributed unevenly, efforts to ‘keep up with the Joneses’ may increase consumption and, hence, lead to a consumption‐driven profit‐led regime.     

WAGE POLICY IN AN OPEN‐ECONOMY KALECKI–KALDOR MODEL: A SIMULATION STUDY

This paper discusses a Post‐Keynesian model of income, production and trade. The one‐country, one‐sector model features Kaleckian investment demand, Kaldorian productivity and a labor market module based on a wage–price spiral. The model is first presented for a closed economy with exogenous real wages; second, for a closed economy with endogenous real wages; third, for an economy open to trade with endogenous real wages. Simulations with different calibrations show key characteristics of the model. Monte Carlo simulations over reasonable parameter ranges shed some light on the effectiveness of wage policies in open economies.     

Foreign direct investment and wage differentials in Taiwan

Abstract

The ease of restrictions on foreign direct investment in China since 1990 has attracted a continuous and dramatic flow of outward investment from Taiwan to the mainland. At the same time, the relative wages for skilled workers in Taiwan have risen mildly despite a rapid increase in the share of educated workers in its labor market. The aim of this paper is to explore the linkage between capital outflows to China and the wage share of skilled workers in Taiwan over the period 1991 – 2001. We find that the pattern of changes in relative wages is consistent with shifts in the relative demand for skilled labor. For the most part, the increases in the relative demand for skilled workers could be attributable to within-industry factors. Findings also indicate that outward direct investment to China has a significantly positive impact on the skilled labor wage share.     

Trend and business cycles with external markets: Non‐capacity generating semi‐autonomous expenditures and effective demand

The Global Financial Crisis has underlined the importance of developments in the household sector to explaining macro patterns. Some recent papers have discussed the role of non‐capacity generating semi‐autonomous expenditures in growth theory. This literature ties together several aspects of heterodox thought: growth and distribution; the Sraffian supermultiplier; Duesenberry's relative income hypothesis; the endogenous money approach and Kalecki–Luxemburg external markets. The basic message is that non‐wage sources of effective demand, based on mortgage and consumer credit, can play a key role in inducing capacity investment and driving long‐run output growth. This article gives a broad overview of the role of financed‐induced semi‐autonomous expenditures in growth, cycles and crises, and thus criticizes some of the previous approaches that claim to mimic actual cycles while abstracting from these crucial determinants of economic activity.     

THE DOUBLE ROLE OF SKILLED LABOR,NEW TECHNOLOGIES AND WAGE INEQUALITY

We examine the relationship between the supply of skilled labor, technological change and relative wages. In accounting for the role of skilled labor in both production activities and productivity‐ enhancing ‘support’ activities we derive the following results. First, an increase in the supply of skilled labor raises the employment share of non‐production labor within firms, without lowering relative wages. Second, new technologies raise wage inequality only in so far as they give incentives to firms to reallocate skilled labor towards non‐production activities. In contrast, skill‐biased technological change of the sort usually considered in the literature does not affect wage inequality.     

SCALE‐INDEPENDENT TECHNOLOGICAL‐KNOWLEDGE BIAS,HUMAN‐CAPITAL ACCUMULATION AND GENDER INEQUALITY

We present a dynamic, non‐scale general‐equilibrium model with female and male human capital where Schumpeterian R&D and human‐capital accumulation are the engines of growth and gender wage inequality. Gender wage inequality is encouraged by changes in relative supply and relative demand of both human‐capital types. Relative supply restricts the levels of employed human capital. Relative demand is affected by the technological‐knowledge bias, which is driven by the price channel and is affected by human‐capital accumulation. In particular, the female‐premium per unit of human capital and per worker increases when the observed discrimination against women decreases or is removed.     

The economics of the super‐multiplier: A comprehensive treatment with labor markets

This paper links the super‐multiplier to Keynesian macroeconomics, showing it to be the most Keynesian of growth perspectives. Next, the paper shows that the super‐multiplier is a micro‐economically coherent theory of investment and capital accumulation. Firms’ decisions regarding capital accumulation coordinate demand and supply growth in goods markets. The paper then explores the implications of incorporating the super‐multiplier in the neo‐Kaleckian and Cambridge growth models. Lastly, it shows how labor markets and unemployment can be added into super‐multiplier models to provide a comprehensive growth model that addresses Solow's (1956, Journal of Economics, 70, 65–94) labor market knife‐edge problem. Incorporating labor markets does not change the fundamental super‐multiplier result that growth is determined by the growth of autonomous demand.     

Cost share‐induced technological change and Kaldor’s stylized facts

This paper presents a theory of induced technological change in which firms pursue a random, local, and bounded search for productivity‐enhancing innovations. Firms implement profitable innovations at fixed prices, which then spread through the economy. After diffusion, all firms adjust prices and wages. The model is consistent with a variety of price‐setting behaviors, which determine equilibrium positions characterized by constant cost shares and productivity growth rates. A fixed mark‐up can yield Marx‐biased technological change. Target‐return pricing yields Harrod‐neutral technological change with a fixed wage share as a stable equilibrium, consistent with Kaldor's stylized facts, while allowing for deviations from equilibrium, as observed in the longer historical record.     

Impact of Trade on Canada's Employment,Skill and Wage Structure

Using newly constructed data for 88 Canadian industries (including primary, manufacturing and services), for 15 years (1992–2007), we analyse the impact of trade and technological change on labour demand, skill structure, wage premiums and welfare in Canada. Results show that export growth has no impact, whereas import growth reduces employment growth. But contrary to popular belief, Canada's job loss due to imports has been very small, only about 6,000 persons annually. China's negative impacts are more pronounced in industries where the share of information and communication technology (ICT) capital is rising fast and among low R&D intensive industries. In terms of skill change, ICT use and real exchange rate appreciation are biased towards high skill workers. Imports from the United States and China are skill‐neutral, whereas imports from Mexico are skill‐upgrading. Overall, neither export nor import growth has an impact on the wage rate. However, had there been no imports from China, the annual wage growth rate of high skill manufacturing workers would have been 0.6 per cent higher. Between 1992 and 2007, there was an annual net gain from the rise in imports at about 0.4 per cent of GDP, in addition to the gains obtained from 1992 import levels vis‐à‐vis autarky.     

SEARCH AND STOCHASTIC DYNAMICS IN THE OLD KEYNESIAN ECONOMICS: A RATIONALE FOR THE SHIMER PUZZLE

Following Farmer's micro‐foundation of the General Theory, I build a competitive search model in which agents are divided in two categories, i.e. wage and profit earners. Within this framework, I show that the model economy has a continuum of equilibria that might be consistent with a certain degree of endogenous real stickiness. Moreover, calibrating and simulating the model in order to fit US first‐moment data, I show that this setting can provide a rationale for the Shimer puzzle, i.e. the relative stability of labor productivity in spite of the large volatility of labor market tightness.     

Induced Innovation,Endogenous Technical Change and Income Distribution in a Labor‐Constrained Model of Classical Growth

We present a steady state analysis of a labor‐constrained classical growth model with endogenous direction and intensity of technical change. Firms use retained profits to raise their productive capacity and to improve labor and capital productivities. Investments are planned to maximize instantaneous profits. Comparative dynamics exercises show that (1) an increase in the saving rate and in R&D subsidies raises the steady state labor share, labor productivity growth and the employment rate, and (2) a rise in workers' bargaining power reduces the employment rate while leaving productivity growth and distribution unaffected.     

THE PROFIT–INVESTMENT–UNEMPLOYMENT NEXUS AND CAPACITY UTILIZATION IN A STOCK‐FLOW CONSISTENT MODEL

This paper studies under which conditions the share of profit in value‐added, financial constraints on investment and capital shortage may foster unemployment and may limit the growth of capital and/or the growth of aggregate demand, in a stock‐flow consistent model. The efficiency of demand‐side versus supply‐side economic policies (decrease of the real interest rate and/or of the real wage, increase of the leverage ceiling constraint) depends on capital shortage and credit rationing, which are not necessarily simultaneous due to the effects of investment on aggregate demand and supply.     

On the inflation-unit labor cost relation

This paper investigates the independent effects of wage and productivity growth on inflation utilizing Weintraub's Wage-Cost-Markup (WCM) model. An Alternative WCM model formed by considering asymmetry in adjustment speeds of wage and productivity growth on pricing produces long-run effects conforming to a priori expectations concerning the magnitude and equality of inflation's response to wage and productivity growth. The model also produces improved predictive performance when compared with an estimated equation relating inflation to current unit labor cost growth. The findings offer a price equation that can be employed in econometric models relating inflation to unit labor cost growth.     

Income shares,secular stagnation and the long-run distribution of wealth

Four alarming stylized facts have recently emerged in the United States: (a) a decline in the labor share of income; (b) a decline in labor productivity; (c) an increase in the top 1% wealth share and (d) an increase in the capital-income ratio. In Capital in the XXI Century, Thomas Piketty's argument is that the r > g inequality determines an increase in the capital-income ratio; if the elasticity of substitution in production is above one, the profit share rises. We provide a contrasting explanation that draws from the Post Keynesian approach to differential saving propensities between classes and the Classical-Marxian theory of induced technical change. In a simple model of “capitalists” and “workers,” we show that institutional changes that lower the labor share—declining unionization, increasing monopsony power in the labor market, the global ‘race to the bottom' in unit labor costs or the exhaustion of path-breaking scientific discoveries—can reduce labor productivity growth because of the lessened incentives to innovate to save on labor costs. A falling labor share reduces workers' total savings, and wealth concentrates in the capitalists' hands. A higher profit share and wealth share both put pressure on accumulation: but the long-run growth rate, which is anchored to labor productivity growth, has fallen. To restore balanced growth, the capital-income ratio must rise, independent of the elasticity of substitution. These tendencies are not inevitable: taxation can be used to implement any wealth distribution targeted by policymakers, while worker-crushing institutional arrangements can also in principle be reversed through policy. Neither change appears likely given the current institutional and global policy climate.     

KEYNES' WAGE–PRICE DYNAMICS

The paper presents a simple loglinear macroeconomic model designed to discuss the essentials of Keynes' dynamic analysis in the General Theory and in the Treatise on Money. The model has a conventional static Aggregate Demand—Aggregate Supply block plus a three‐dimensional dynamic system involving the money wage and the expected level and rate of change of the output price. It illustrates Keynes' ideas, in particular on the nature of unemployment and on the stabilizing nature of money (as opposed to real) wage stickiness. It also allows to reconcile with empirical observations Keynes' (false) conjecture on the negative correlation of money and real wages.     

Redistribution of Trade Gains in the Presence of Firm and Worker Heterogeneity

Trade gains are unequally distributed; in particular, low‐ability workers lose out in terms of wages and employment probability. In this paper, we investigate the impact of redistribution schemes on aggregate and disaggregate variables. To this end, we built a trade model with trade unions, heterogeneous firms and workers. Three redistribution schemes are distinguished: unemployment benefits financed by either a wage tax, a payroll tax or a profit tax. We find that: (i) all three redistribution schemes reduce output per capita; (ii) but the marginal reduction is lowest in the wage tax funding scenario; and (iii) If the profit tax is used, labour demand for low‐ability workers increases.     

A Kaldor–Hicks–Goodwin–Tobin–Kalecki model of growth and distribution

This paper presents a Kaldorian model of growth that incorporates both Kaldor's theory of income distribution and his endogenous technical progress function. Growth is driven by demand‐side forces that induce supply‐side accommodation. The model incorporates Hicksian induced innovation; Goodwin Marxist style labor conflict that affects wage bill division between workers and managers; Tobin inflation effects; and Kalecki monopoly power effects. Unlike the neo‐Kaleckian model, a Kaldorian economy operates at normal capacity utilization. Monopoly power plays a role as a barrier to entry rather than determining the functional distribution of income.
