The Limits to Wage‐Led Growth in A Low‐Income Economy

Neo‐Kaleckian literature has actively debated whether growth is wage‐ or profit‐led in capitalist economies. However, existing studies tend to ignore the non‐tradable sector and heterogeneity within the tradable sector. This article shows that incorporating these features renders wage‐led growth in an open developing economy unfeasible in the traditional (Kaleckian) sense of the term. This result—which follows even if one sets aside the competitiveness considerations generally seen as impeding such growth—occurs due to the presence of a homogeneous goods‐producing tradable sector that sets the ceiling to steady‐state growth. A corollary, in light of findings from the ‘new new trade theory’ literature, is that increasing South‐South trade may tend to narrow room for wage‐led growth regardless of the other desirable effects of higher wages.     

DUAL LABOR MARKETS AND THE IMPACT OF MINIMUM WAGES ON ATYPICAL EMPLOYMENT

We present a growth model that contains minimum wages as one important element of a flexicurity economy where we allow for heterogeneous labor and for real wage rigidities. We show that the wage‐setting process, in its reference to the reservation wage of the first labor market, is crucial as regards stability of the economy and persistent or explosive oscillations may occur, in particular when the influence of the reservation wage on wage formation in the first labor market becomes too strong. Further, minimum wages can alleviate the negative consequences of economic downturns and help stabilize the economy.     

Redistribution in a Neo‐Kaleckian Two‐country Model

We investigate the interaction between demand‐driven growth and income distribution in open economies, by combining expenditure‐switching and demand spillover effects in a neo‐Kaleckian two country model. First, we specify elasticities of wage share and real exchange rate to the money wage relative to labor productivity, in order to precisely describe the distributive pass‐through from money wages to the labor share and the real exchange rate. Second, we analyze the demand effects of an increase in the money wage for given labor productivity (a redistribution towards labor) in both Home and Foreign country, as well as globally. We derive closed form results for two identical countries. These results indicate that redistribution towards labor at Home: (i) always increases growth globally if Home is wage‐led, but can lead to lower growth at Home relative to Foreign; and (ii) will always imply lower growth at Home relative to Foreign if Home is profit‐led, but can still be growth‐enhancing at Home. Thus, to the extent that countries are concerned with their relative economic performance, a fallacy of composition can emerge. Numerical simulations suggest that these fallacies could indeed occur. As a consequence, ‘returns to coordination’ over international labor policies might be substantial.     

Trade liberalization in asian newly industrialized countries

Singapore, South Korea, and Taiwan are often perceived as having achieved similar trade patterns; nevertheless, their trade policies and patterns differ in fundamental respects. In this study, three models are considered and different aspects of the trade liberalization policies of these three countries are highlighted. The model of South Korea underscores the significance of product market concentration in restraining real wage growth and contributing to income inequality. The model of Singapore highlights the role of foreign investment in producing manufactured goods for export and in raising real wages. The factor proportions model of a labor-abundant economy adequately describes the Taiwanese liberalization. The model's predictions of rising real wages and no monopoly profits are consistent with Taiwan's declining income inequality.     

Endogenous norms in wage and price setting and hysteresis in the real exchange rate

Real exchange rates are often ‘disconnected’ from fundamentals. Mean reversion toward equilibrium operates at a slow pace (if it operates at all), and when inflation is low the real exchange rate tracks closely the nominal exchange rate for prolonged periods of time. Using a simple open economy model, we show that including endogenous norms in wage and price setting in an open economy set‐up can lead to hysteresis in the real exchange rate. For a given set of fundamentals, the real exchange rate may settle down at different equilibria and exchange rate policies are not necessarily neutral in the long‐run.     

Monopsony distortions in an open economy: A theoretical analysis

This paper examines the positive and welfare implications of monopsony distortions in a small open economy. The equilibrium when one industry exercises its monopsony power is characterized by an endogenous differential between the marginal rates of substitution in production between the two industries. This monopsony distortion leads to various pathological positive results, including non-tangency of the commodity price-ratio with the shrunk-in distorted PPC, output responses unrelated to the convexity or concavity of the distorted PPC, reverse Stolper-Samuelson results, and opposite movements in real wages and real incomes. In addition, the welfare effect of trade liberalization is of ambiguous sign.     

Mind the Gender Wage Gap – the Impact of Trade and Competition on Sectoral Wage Differences

This paper examines differences between women’s and men’s wages in 18 selected OECD countries in the period 1970 to 2005. The study is based on 12 manufacturing sector‐ and skill‐specific sets of panel data on the gender wage gap. We apply a system generalised method of moments (GMM) estimator to the extended version of the conditional gender wage gap convergence equation, controlling for sector concentration and industry‐specific measures of openness using a difference‐in‐difference approach: trade‐affected concentrated sectors versus trade‐affected competitive sectors. The results indicate that: (i) an increase in sector concentration is associated with wage gap growth; (ii) both import and export penetration are associated with a reduction of the high‐skill gender wage gap growth in concentrated industries; (iii) there is evidence of a widening impact of trade on the medium and low‐skill occupational gender wage gap growth in less competitive industries; (iv) institutional regulations of the labour market have an impact on the development of the gender wage gap: for highly‐skilled labour an increase in labour market regulation raises the growth of the gender wage gap, while for medium‐ and low‐skilled workers, it lowers it.     

EXTERNAL SHOCKS AND THE URBAN POOR

This paper examines the effect of external shocks on urban poverty in a two‐household (rich and poor), two‐sector intertemporal model of an open economy with segmented labor markets. Skilled and unskilled labor are used in the formal sector, whereas only unskilled labor (which moves freely across sectors) is used in the informal economy. The extent to which a permanent increase in the world risk‐free interest rate affects the incidence and depth of poverty is shown to depend crucially on the wedge between consumption and product wages. The model is also extended to account for endogenous minimum wages and capital accumulation.     

Wage Inequality in the United Kingdom: Trade and/or Technology?

I employ two alternative intra‐industry trade Applied General Equilibrium (AGE) models to explain some stylised facts of the British economy. The model with skill‐biased technical change (i.e. exogenous skill‐biased technical change à la Solow) can explain the rise in wage inequality between skilled and unskilled workers, the decline in manufacturing and the expansion of modern services. However, the model where technical change is trade‐induced (i.e. endogenous sector‐biased technical change à la Romer) performs better, because it can also explain the exponential rise of imported intermediate capital goods and developments in the wage rate of unskilled workers.     

Trade, technology, and the rise of the service sector: The effects on US wage inequality

This paper uses a multi-sector version of the Ricardo-Viner model of international trade to quantify empirically the effects of technological changes, international trade, changes in the sectoral composition of the economy, and other factors on the US wage premium. The main finding of the paper is that changes in the sectoral composition of the economy were the most important force behind the widening of the wage gap, accounting for about 60% of the relative increase in wages of skilled workers between 1970 and 1996. In essence, capital was reallocated to sectors where it is relatively complementary to skilled workers.     

Balance‐of‐payments‐constrained cyclical growth with distributive class conflicts and productivity dynamics

This study builds a dynamic balance‐of‐payments‐constrained model that incorporates the endogenous determination of the economic growth rate, conflictive wage/price distribution and employment rate. The wages, commodity prices and employment rate are determined by the profit squeeze effect and labour‐saving technical change. The relative strength of these two effects generates different outcomes for the transitional dynamics and comparative statics analysis. Particularly, the model shows stability, instability and cyclical nature, the latter of which concurs with the evidence reported by previous empirical studies.     

THE WAGE–WAGE‐ . . . ‐WAGE–PROFIT RELATION IN A MULTISECTOR BARGAINING ECONOMY

The equalization of profit rates across industries subject to firm‐level bargaining over wages generates an interindustry wage structure with higher wages in capital‐intensive sectors. The familiar inverse wage–profit relation gives way to a wage–wage‐ . . . ‐wage–profit surface on which the profit rate can vary directly with the wage paid in an individual industry. Institutional changes that decrease workers' bargaining power and increase the incomes of the unemployed tend to compress the wage distribution; these changes draw political support from cross‐class coalitions of low‐wage workers and capital‐intensive firms. Some capital‐using, labor‐saving technical changes that raise capitalists' profits in current prices lower the equilibrium profit rate.     

The effects of a minimum wage on foreign factor rewards

A two-sector model is used to examine the effects on the foreign real wage of a binding minimum real wage introduced into an economy with monopoly power in trade. It is shown that the foreign real wage may fall in response to the introduction of a domestic wage floor.     

Trade, wages, and the political economy of trade protection: evidence from the Colombian trade reforms

Worker industry affiliation plays a crucial role in how trade policy affects wages in many trade models. Yet, most research has focused on how trade policy affects wages by altering the economy-wide returns to a specific worker characteristic (i.e., skill or education) rather than through worker industry affiliation. This paper exploits drastic trade liberalizations in Colombia in the 1980s and 1990s to investigate the relationship between protection and industry wage premiums. We relate wage premiums to trade policy in an empirical framework that accounts for the political economy of trade protection. Accounting for time-invariant political economy factors is critical. When we do not control for unobserved time-invariant industry characteristics, we find that workers in protected sectors earn less than workers with similar observable characteristics in unprotected sectors. Allowing for industry fixed effects reverses the result: trade protection increases relative wages. This positive relationship persists when we instrument for tariff changes. Our results are in line with short- and medium-run models of trade where labor is immobile across sectors or, alternatively, with the existence of industry rents that are reduced by trade liberalization. In the context of the current debate on the rising income inequality in developing countries, our findings point to a source of disparity beyond the well-documented rise in the economy-wide skill premium: because tariff reductions were proportionately larger in sectors employing a high fraction of less-skilled workers, the decrease in the wage premiums in these sectors affected such workers disproportionately.     

MONETARY AND FISCAL INTERACTIONS: SHORT‐RUN AND LONG‐RUN IMPLICATIONS

We model policy interactions in a growing economy. Unemployment can persist and matters for the real wage; conflicting claims underpin inflation outcomes; and aggregate demand determines capacity utilization and unemployment. Monetary policy is characterized by a Taylor rule. Fiscal policy is characterized by a marginal tendency to run deficits or surpluses. We address three questions: can monetary policy ensure macroeconomic stability in the absence of coordinated fiscal policy, can fiscal policy ensure macroeconomic stability when the monetary authority pegs the interest rate, and can policy authorities trade‐off some sustained inflation for a long‐run improvement in unemployment rates?     

Globalisation and Inter‐occupational Inequality: Empirical Evidence from OECD Countries

How does globalisation affect inter‐occupational wage inequality within countries? This paper examines this by focusing on two dimensions of globalisation: openness to trade and openness to capital flows, using a relatively new data set on occupational wages. Estimates from a dynamic model for 15 OECD countries spanning the period 1983–2003 suggest that increased openness increases occupational wage inequality in poorer OECD countries as predicted by the Heckscher–Ohlin–Samuelson model, but for the more advanced OECD countries, we find no significant effect. The absence of the expected result for the latter category can be due to a rapid increase in the supply of skilled labour, to outsourcing of skilled jobs or because changes in the trade flows are too small to have any significant effect in those countries.     

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.     

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.     

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.     

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.
