Stochastic and Club Convergence in Real Wages in European Union: Evidence from Aggregate and Sector Level Data

The paper examined real wage convergence across 27 European economies, at aggregate and sectoral levels, using the panel unit root tests of stochastic convergence and the club clustering procedure. Convergence was absent for a panel as a whole, but present within the clubs. In most sectors, the common component of the relative wages was stationary, while idiosyncratic component contained unit roots, suggesting the country- and sector-specific drivers of convergence and only transitory effects of exogenous forces. The most pronounced club convergence was observed in the sectors characterized by significant labor mobility, knowledge intensity and speed of technological change.

Real Wage Convergence in Romania: Empirical Evidence Based on Club Converging

Abstract The study aims to explore the real wage convergence across the 42 Romanian counties from 1991 to 2016 by using the convergence algorithm developed by Phillips and Sul (2007). The process of divergence is identified in the period of 1991-2016 as well as a number of 4 convergence subgroups (clusters). Transitional curves indicate that over the long-run the real wage tends to converge. Policy implications of the paper’s findings are also provided.

The intertemporal evolution of agriculture and labor over a rapid structural transformation: Lessons from Vietnam

We combine nationally representative household and labor force survey data from 1992 to 2016 to provide a detailed description of rural labor market evolution and how it relates to the structural transformation of rural Vietnam, especially within the agricultural sector. Our study adds to the emerging literature on structural transformation in low-income countries using micro-level data and helps to answer several policy-related questions. We find limited employment creation potential of agriculture, especially for youth. Rural-urban real wage convergence has gone hand-in-hand with increased diversification of the rural economy into the non-farm sector nationwide and rapid advances in educational attainment in all sectors’ and regions’ workforce. Minimum wage laws seem to have played no significant role in increasing agricultural wages. This enhanced integration also manifests in steady attenuation of the longstanding inverse farm size-yield relationship. Farming has remained securely household-based and the family farmland distribution has remained largely unchanged. Small farm sizes have not obstructed mechanization nor the uptake of labor-saving pesticides, consistent with factor substitution induced by rising real wage rates. As rural households rely more heavily on the labor market, human capital accumulation (rather than land endowments) have become the key correlate of improvements in rural household well-being.

The Decline of the U.S. Labor Share Across Sectors

This paper provides novel insights on the changing functional distribution of income in the post-war US economy. We present a Divisia index decomposition of the US labor share (1948–2017) by fourteen sectors. The decomposition method furnishes exact contributions from four components towards aggregate changes of the labor share: sectoral real compensation, sectoral labor productivity, the structure of the economy as measured by employment shares, and the structure of markets as measured by relative prices. Results are presented for the entire period as well as the “golden age” (1948–1979) and a “neoliberal era” (1979–2017), painting a rich and detailed picture of structural changes in the US economy. The manufacturing sector plays a dominant role: despite its continuously falling employment share, growth of real compensation matches that of labor productivity in the early period but falls far behind during the neoliberal era. Further, employment shifts towards stagnant sectors with relatively low real wages and productivity. We discuss these results in the context of Baumol’s and Lewis’s seminal contributions on dual economies. While the cost disease is apparent—employment shifts towards stagnant sectors, their relative prices rise, and the aggregate growth rate (of productivity) decreases—the originally suggested mechanism of upward real wage convergence is muted. The observed changes are instead compatible with a “reverse-Lewis” shift, where stagnant sectors act as a labor surplus sink, and dynamic sector labor experiences slowing real wage growth.

Does real wage converge in China?

This study adopts flexible Fourier unit root test proposed by Enders and Lee (Oxf Bull Econ Stat 74(4):574, 2012) to explore real wage convergence in China in the process of market-oriented reform. We find that our approximation has higher power to detect U-shaped and smooth breaks than linear method if the true data generating process of relative real wage is in fact a stationary non-liner process. The empirical results show that property of stationarity of relative real wage varies across different regions. Specifically, stationarity prevails in eastern and western regions, implying the regional development strategies launched there enhance labor migration, commodity trade and thus wage convergence. In contrast, almost all provinces in northeastern and central regions show non-stationarity, indicating the strategies there are less effective in promoting wage convergence. These results have practical policy implications for China’s regional development and income equality.

Regional wage convergence in Spain 1850–1930

This paper presents a new regional database on real wages for Spain from 1850 to 1930. This evidence is used to analyze the evolution of wages across regions and occupations. Substantial wage convergence occurred from 1850 to 1914, despite low rates of internal migration. World War I and the subsequent globalization backlash were associated with a spectacular increase in wage differentials. However, real wage convergence across Spanish provinces resumed during the 1920s, this time accompanied by high rates of internal migration.

Tests of the Factor Price Equalization Theorem

Using annual data for 21 OECD countries over the period 1960 to 1993 this paper tests whether real wages have converged to a common mean alongside with increasing openness, as predicted by the factor price equalization theorem. The empirical estimates suggest that real wage convergence has taken place in most OECD countries. ([EL F02, J3)
