Disentangling the wage-productivity relationship: Evidence from select OECD member countries

Conventional theory proposes that firms reward productivity improvements with higher wages. Conversely, efficiency wage theory suggests that wages can induce greater productivity. This paper applies a statistical technique that disentangles the potential bidirectional feedback between wages and productivity. Wage strategies in six industrialized countries with various labor market institutions are examined. Conventional and efficiency wage practices vary systematically across the industrialized countries; these variations are consistent with the expected effects of labor market institutions.     

Is more mobility good?: Firm mobility and the low wage–low productivity trap

This paper explores the possibility that unregulated FDI flows are causally implicated in the decline in labor productivity growth in semi-industrialized economies. These effects are hypothesized to operate through the negative impact of firm mobility on worker bargaining power and thus wages. Downward pressure on wages can reduce the pressure on firms to raise productivity in defense of profits, contributing to a low wage-low productivity trap. This paper presents empirical evidence, based on panel data fixed effects and GMM estimation for 37 semi-industrialized economies that supports the causal link between increased firm mobility and lower wages, as well as slower productivity growth over the period 1970–2000.     

Robots and humans – complements or substitutes?

The effect of the spread of Artificial Intelligence (AI) on wages depends on both the form of aggregate production relationships and the elasticity of substitution between human and robotic labor. With a conventional production function involving labor, robots, and ordinary capital, an increase in robotic labor can have either a positive or a negative effect on wages. Alternatively, it is possible to estimate the aggregate production relationship without measuring capital or other fixed factors explicitly, using the procedure developed by Houthakker in the 1950s. Houthakker's method is based on the probability distribution of the productivity of the variable factor. Fitting different distributions to cross-sectional data on U.S. productivity, it is shown that if the elasticity of substitution between human and robotic labor is greater than about 1.9, the burgeoning of AI technologies will cause a decline in aggregate wages, other things equal. For the manufacturing sector, an even smaller human-robot elasticity of substitution is likely to result in declining wages of industrial workers as robots proliferate.     

The Fallacy of Free Trade *

The purpose of this paper is to explode the myth of free trade. Productivity and real wages in the United States rose sharply between 1950 and 1972, but since then real earnings have been falling in spite of a continuous rise in productivity. It turns out that America was more or less a closed economy until 1972, as its trade/GNP ratio was close to 10%; but since then it has become an open economy. the theoretical model shows how real wages may fall in an open economy, but not in a closed economy, in spite of rising productivity.     

MNEs and wages: The role of productivity spillovers and imperfect labor markets

Disentangling the labor market implications of increased foreign capital flows remains important. This paper provides a unifying framework allowing to study the wage implications of multinational enterprise (MNE) activities, pointing to the importance of controlling for both labor market imperfections and productivity spillovers from foreign to local firms. Results show that increased MNE activities increase average wages in the local economy while contributing to a larger wage dispersion between the MNE and local firms. While the results pertaining to average wages depends heavily on the frictions in the labor market, how much the wage dispersion alters also depends on the extent of productivity spillovers from the MNEs to the local firms and the complementarity between domestic and foreign capital.     

ARE WAGE INCREASES IN CHINESE STATE INDUSTRY EFFICIENT? PRODUCTIVITY IN NANJING'S MACHINE-BUILDING INDUSTRY

Since China's economic reform began, wages in state enterprises have increased at rates much faster than the rate of price inflation. This paper investigates the source of this rapid wage increase for a sample of Chinese state-owned machine-building enterprises to determine whether increased wages can be best explained by changes in productivity, changes in the output market, or changes in input markets. CES production function estimates find the marginal product of labor was stagnant between 1980 and 1992 but initially higher than wages. Rising wages were therefore consistent with other evidence that the reform process cost the state sector its labor monopsony. ( JEL P31)     

Privatization and efficiency wages

The impact of privatization is investigated in a shirking model of efficiency wages. Without trade unions, privatization — modeled as a stricter control of employees — lowers wages and raises employment, output, and profits, while effort and productivity effects depend on the employees' risk aversion. However, for a utilitarian monopoly union, facing a company characterized by a constant-elasticity labor-demand schedule, privatization raises efficiency wages. If privatization is modeled as a stronger profit orientation, wages, effort, and labor productivity will rise, while employment will shrink in a wage-setting firm. Again, wage and employment effects can be reversed in the case of wage negotiations.

Changes in income distribution and welfare from greater immigration of unskilled workers

This paper considers the consequences of greater immigration of unskilled labor on income distribution and welfare in the receiving country. To address these issues, both the sending and receiving countries are represented in a static general equilibrium model which distinguishes between skilled and unskilled labor and which allows prices to be determined endogenously. In this framework an inflow of unskilled labor is likely to reduce wages of unskilled labor, but whether capital or skilled labor benefits depends upon demand elasticities, elasticities of substitution in production, and differences across countries in the productivity of unskilled labor. National welfare in the receiving country is likely to rise, to the extent that the relative price of importable goods falls, non-residents already in the country receive lower wages, immigrants receive lower wages than those paid to domestic workers, and immigrants cause little increased demand for public services and transfer programs.     

Minimum Wages and Firm Productivity: Evidence from Vietnamese Manufacturing Firms

ABSTRACT

This paper empirically examines the minimum-wage impact on firm productivity. Using a detailed Vietnamese firm-level dataset from 2010 through 2015, the regression results suggest that firms raise their labor productivity, total factor productivity, capital intensity and revenue in response to increased minimum wage standards. Firms that pay their workers below the minimum wage react more positively in raising their labor productivity than high-wage firms. Minimum wages has had a more pronounced impact on firms’ labor productivity, total factor productivity and capital intensity since the uniform wage rate was introduced for both domestic private and foreign-invested enterprises in 2012.     

Wage differentials, discrimination and efficiency

I analyze a large labor market where homogeneous firms post wages to direct the search of workers who differ in productivity. I show that the model has a unique equilibrium. The wage differential depends positively on the workers’ productivity differential only when the latter is large. When the productivity differential is small, high-productivity workers get a lower wage than low-productivity workers. This reverse wage differential remains even when the productivity differential shrinks to zero. However, the equilibrium is socially efficient. High-productivity workers always get the employment priority and higher expected wages than low-productivity workers. Although discrimination in terms of expected wages does not exist, conventional measures are likely to incorrectly find discrimination in the model.     

Labor market institutions and industrial performance: an evolutionary study

This study investigates the impact of labor market institutions on industrial performance from a Schumpeterian perspective. We suggest that labor market institutions play a very important role in the process of creative destruction, because they may create an environment that encourages and enforces innovation, and help to reallocate resources, most importantly labor, through swift elimination of weak performers. We specifically look at the effects of the quantity of labor market regulations and inter-industry wage differentials on labor productivity for a panel of 44 countries for the period 1965–1999. Our findings suggest that those countries that introduce more regulations on conditions of employment and wages achieve higher levels of productivity. Moreover, wage compression raises productivity by reallocating resources to productive activities.     

Endogenous contract structure and monetary policy

We analyze the co-determination of monetary policy and the labor contracts chosen by members of the public, who can either fix or index their nominal wages. Fixed nominal wages allow the central bank to offset productivity shocks, while the public fix nominal wages in response to the central bank offsetting shocks; so there is an equilibrium in which, realistically, nominal wages are fixed and shocks offset: a result which holds in single- as well as in multi-period games. In addition, there may be equilibria in which agents index their nominal wages, and the central bank optimally responds by stabilizing price. In contrast to conventional models, the Ramsey rule may be implemented in a finitely repeated game. The central bank does not deviate for fear that agents would change their labor contracts such that the central bank's least favored equilibrium will subsequently be played.     

Real wages and labor-saving technical change: evidence from a panel of manufacturing industries in mature and labor-surplus economies

Recent theories have provided a persuasive account of a key stylized fact of mature economies: the common long-run trends of average real wages and labor productivity, and the ensuing stationarity of functional distribution. Central to these theories is the notion of directed technical change, which claims that a rise in labor costs sparks the adoption of labor-saving innovations. This paper empirically examines a core prediction of these theories, namely that shocks to functional distribution elicit compensatory adjustments in real product wages and labor productivity. Using two disaggregated data-sets of manufacturing industries (EU-Klems and Unido), I find evidence of cointegration and two-way, long-run Granger causality between these two variables. These findings suggest that directed technical change is indeed key for producing stationarity in functional distribution, and they complement the recent empirical literature on distributive cycles and productivity growth. Preliminary evidence from the Unido data-set also suggests the importance of directed technical change in developing countries. To illuminate the empirical procedure, I present a theoretical model of growth and distribution with directed technical change.     

The Division of Labor, Inequality and Growth

We present a model that links the division of labor and economic growth with the division of wealth in society. When capital market imperfections restrict the access of poor households to capital, the division of wealth affects individual incentives to invest in specialization. In turn, the division of labor determines the dynamics of the wealth distribution. A highly concentrated distribution of wealth leads to a low degree of specialization, low productivity, and low wages. In that case workers are unable to accumulate enough wealth to invest in specialization. Hence, in a highly unequal society, there is a vicious cycle in which the degree of specialization, productivity and wages stay low, wealth and income inequality stays high and the economy stagnates. By contrast, greater equality increases investment in specialization and leads to a greater division of labor and higher long run development.     

The role of unit labor costs in African manufacturing investment and export performance

Several studies have pointed out that manufacturing wages are relatively higher in African countries than in other countries at similar levels of development, and that this contributes to the continent's lower levels of manufacturing competitiveness. This paper derives unit labor costs (ULCs)—average wages relative to productivity—for two-digit manufacturing sectors across a sample of 79 developed and developing countries, including 13 African countries, over the 1990–2015 period. We benchmark the ULCs to China and estimate the relationship between relative ULCs and manufacturing sector investment rates and export performance. We find that relative ULCs have a smaller association with exports in Africa relative to other developing regions. There is some evidence that investment responds to changes in relative ULCs in Africa; however, the estimated effects are smaller than in the full sample. Further, we find that for Africa, the level of labor productivity has a quantitatively stronger and more robust association with manufacturing performance than the level of real wages. The results have important implications for industrial policy in African countries.     

Labor-Leisure Choice and Relative Income Concerns in the Shadow of the Housing Market

We theoretically examine the connection among labor productivity, work time, and housing costs in an economy with households differing in wages and neighborhoods differing in quality. We argue that the location rent component of housing cost is key to explicating the connection. We trace how the housing market makes relative income instrumental for maximizing utility even if households’ utility functions are not interdependent. Over time, productivity growth yields higher wages but households compete some of that away on the housing market. This structural inflation of location rents counteracts preferences to work less as wages rise and hinders the expansion of leisure. Relative income effects are shown to arise as a consequence of a market institution that monetizes socially-imbued preferences.     

Recalculating the agricultural labor force in China

In this study, we use a hypothetical method to recalculate the agricultural labor force based on statistical data on the labor force in China. We confirm the revised agricultural labor force data by estimating the agricultural production function. Through comparing the marginal labor productivity with the subsistence level of wages in the agricultural sector, we find that the overstated figures of agricultural labor force not only result in the underestimation of agricultural labor productivity but also are misleading by indicating that China reaches the Lewis turning point later than in actuality. The process of labor transfer in China, a large part of which is through rural migrant workers, has been much faster than expected.     

Labor Informality: Choice or Sign of Segmentation? A Quantile Regression Approach at the Regional Level for Colombia

The labor market in developing countries is remarkably heterogeneous, with a small productive formal sector characterized by high wages and attractive employment conditions, and a large informal sector characterized by low productivity and volatile wages. The informal sector is particularly diverse. In this paper, we examine the heterogeneity of the informal sector at the regional level in Colombia. In general, our findings suggest that both voluntary and involuntary informal employment co‐exist by choice and as a consequence of labor market segmentation. We also find that there are striking differences in labor market characteristics across cities, particularly with respect to informal employment.
