THE IMPORTANCE OF SKILL MEASUREMENT FOR GROWTH ACCOUNTING

In a growth accounting context one usually constructs a quality adjusted index of labor services by aggregating over predefined groups of workers, using the groups' relative wage bills as weights. In this article we suggest a method based on decomposing individual predicted wages into a skill‐related part and a part unrelated to skill, where the former consists of both observed and unobserved components. The predicted wages, associated with individual skill attributes, are sorted and classified into deciles. The median predicted skill‐related wage in each decile is used to construct an alternative skill‐adjusted index of labor services. We find that total factor productivity (TFP) growth decreases significantly when using the latter method. This means that when using the alternative method one explains more of the growth in labor productivity than what a more traditional labor quality adjustment procedure does.     

Economic Growth and Wage Stagnation in Peru: 1998–2012

From 1998 to 2012, the Peruvian economy exhibited rapid growth. Moreover, the composition of the labor force improved in terms of education and experience, two variables that are typically associated to higher human capital. The average worker in 2012 had a higher level of education and was one and a half years older than in 1998, reflecting the impact of the demographic transition. However, the average real wage was roughly constant. We show that a decline in the wage premium for education, and to a minor extent for experience, is responsible for the lack of growth in the average real wage. Had these two premia remained constant throughout the period of analysis, average labor earnings would have increased by about 2.6% per year, of which 0.7 percentage points are accounted for by the changes in the composition of the labor force in terms of age and education. We explore the role of the relative supply of workers with different levels of human capital as an explanation for the decline in the wage premium for education. Finally, we analyze the implications of these findings for some macroeconomic variables, as earnings and wage inequality, the labor share and total factor productivity.     

Reducing Start‐up Costs for New Firms: The Double Dividend on the Labor Market*

Starting a firm with expansive potential is an option for educated and high‐skilled workers. If there are labor market frictions, this additional option can be seen as reducing the chances of ending up in a low‐wage job and hence as increasing the incentives for education. In a matching model, we show that reducing the start‐up costs for new firms results in higher take‐up rates of education. It also gives rise—through a thick‐market externality—to higher rates of job creation for high‐skilled labor as well as average match productivity. We provide empirical evidence to support our argument.     

QUANTITY OR QUALITY: THE IMPACT OF LABOUR SAVING INNOVATION ON US AND JAPANESE GROWTH RATES, 1960–2004*

This article deals with both theoretical and empirical analyses of the post‐war (1960–2004) growth for the USA and Japan. We investigated three factors contributing to growth: the growth rates of capital, labour and labour saving innovation. In Japan, the growth rate of the labour force has been much less important than its quality improvement—i.e. labour saving technical change—while in the USA, the growth rates of labour and population have contributed more than their quality improvement. The policy implication is that Japan's declining population can be compensated for by additional quality improvement of the existing labour force.     

中国的粮食生产力革命——1953—2003年中国主要粮食作物全要素生产率增长及其对产出的贡献

1953—2003年中国主要粮食的TFP都实现了正向增长,但呈现出明显的波动性特征。以1979年为分界点,中国主要粮食产出增长的源泉经历了一场以投入增加为主向以全要素生产率增长为主的粮食生产力革命。1997年以来中国主要粮食产出增长下降的主要原因是投入要素的下降。从政策角度看,一方面,中国未来要养活自己还主要依赖于粮食生产率的提高,这需要进行一些政策改革以挖掘生产率增长的潜力;另一方面,要提高种粮的收益,建立起可持续的粮食生产投入机制。     

Relative Demand for Skills in Swedish Manufacturing: Technology or Trade?

The rate of change in the share of skilled labor has increased steadily over the past 35 years in Swedish manufacturing. A closer inspection of the period after 1970 indicates that, while relative supply changes of skilled labor seem to have been the main driving force behind the growing skill shares in manufacturing industries over the period 1970–85, an acceleration in the relative demand for skills appears to have propelled higher skill shares during the late 1980s and at the beginning of the 1990s. Consistent with such a development is the finding of an increasing degree of complementarity between knowledge capital and skilled labor, and that Swedish manufacturing firms, in recent years, have invested heavily in R&D. There is also some support for the belief that intensified competition from the South has increased the relative demand for skilled labor. However, the impact appears to be small and essentially driven by the textile industry.     

Skill upgrading and exports

This paper analyzes the effects of international trade on the relative demand for skilled workers in Italian local labor markets. We find that exports cause a sizable skill upgrading in the labor force by increasing the average level of education of the workforce and the share of white-collars workers.     

A REVISIONIST VIEW OF CHINESE AGRICULTURAL PRODUCTIVITY?

Although productivity increased during the initial Chinese agricultural reforms, there is less clarity about subsequent reform efforts. Several studies find that productivity growth either slowed or stopped in the mid-1980s, but these studies use official labor statistics that indicate an increasing farm labor force during the late 1980s and early 1990s. Using an alternative calculation of China's farm labor force showing a decrease in agricultural labor, this article reexamines the data on Chinese agricultural productivity and notes that the changes in productivity appear to correlate to changes in economic policies.     

REAL GROSS DOMESTIC INCOME,RELATIVE PRICES,AND ECONOMIC PERFORMANCE ACROSS THE OECD

This paper uses OECD data to examine changes in labor productivity, real gross domestic product (GDP) and real gross domestic income (GDI), economic aggregates, and relative economic growth over time. Real GDI combines changes in production (real GDP) with a trading gain derived from relative price changes. The paper considers two sources of trading gains: the terms of trade, and the real exchange rate. For OECD countries, the terms of trade is the more important price ratio, making a contribution to real income growth that is, on average, an order of magnitude larger than the real exchange rate. Over long time periods, the most important source of real income growth is changes in production. Over shorter time horizons, however, the trading gain can make noteworthy contributions. Changes in aggregates like real private consumption, or the relative economic performance of nations, are shown to be particularly dependent on the trading gain during the large swings in resource prices that occurred post‐2002.     

PRODUCTIVITY GROWTH IN LATIN AMERICA OVER THE LONG RUN

The low pace of Latin American productivity growth in recent decades, despite extensive economic reforms, has yet to be understood in a longer‐run context where factors such as demographic changes, structural shifts, and investment levels can be taken fully into account. The OxLAD database provides comparable sectoral output and workforce series over 1900–2000 for the six leading economies in the region for the first time. Our analysis of this new dataset shows that: intersectoral resource reallocation reduced aggregate productivity growth in all three periods; total factor productivity growth was low throughout the century, and even negative in the closing three decades; and thus factor accumulation—investment in fixed capital and skilled labor—was the main source of productivity growth in Latin America during the twentieth century.     

DEMOGRAPHIC CHANGE AND INEQUALITY IN THE SIZE DISTRIBUTIONS OF LABOR AND NONLABOR INCOME

This paper utilizes a joint distribution model of labor and nonlabor income that allows us to analyze the impact of demographic change in the U.S. on the marginal distributions of these two income components over time. The beta distribution of the second kind is the hypothetical statistical distribution used in this study to approximate the observed income graduation. This distribution is sum stable which allows us to compare and contrast the marginal distributions in a consistent manner, a property most hypothesized functional forms of income distribution do not possess. We are in effect using a hyperparameter model to do our estimation. We examined the impact of changes over time in labor force participation and population on the marginal distributions of labor and nonlabor income. We disaggregated the variables by sex and age cohorts and found that changes in the age distribution and in the labor supply behavior of women in particular has had a significant effect on the marginal income distributions over time. We also found that the results vary when we examined overall changes in the labor force participation rate vis a vis changes in women's labor force participation separately. The findings are consistent for both income components.     

基于人力资本分布方差的中国国民经济生产函数研究

由于存在劳动力剩余,用就业总量和反映人力资本积累规模的数量指标均难以有效解释中国经济增长。因此,本文用质量指标替代数量指标,选取全部就业人员中具有高中(含职业教育)至大学本科阶段学历者受教育水平的分布方差来测度人力资本,并构建相应的国民经济生产函数,解释中国1997—2009年间的产出增长。研究结果表明:本文提出的方法是有效的,当前中国人力资本投资的边际产出效果高于实物资本投资,职业教育的边际产出贡献高于高等教育。     

GROWTH IN EURO AREA LABOR QUALITY

Composition of the euro area workforce evolves over time and in response to changing labor market conditions. We construct an estimate of growth in euro area labor quality over the period 1983–2005 and show that labor quality has grown on average by 0.47 percent year-on-year. Labor quality growth was significantly higher in the early 1990s than in the 1980s. This strong increase was driven mainly by an increase in the share of those with tertiary education and workers in prime age. Growth in labor quality moderated again toward the end of the 1990s, possibly reflecting the impact of robust employment growth resulting in the entry of workers with lower human capital. The contribution of labor quality to labor productivity has increased over time, accounting for up to one fourth of euro area labor productivity growth. The results point to a lower contribution of total factor productivity to euro area growth.

Life expectancy and economic development: Evidence from microdata

This study examines the effect of life expectancy on fertility, education, and labor force participation. Using birth and sibling histories from the Demographic Health Surveys conducted in sub‐Saharan Africa, I construct a time series of age‐specific birth rates and mortality rates at the country‐region level. I use these data to test the implications of a general equilibrium model linking life expectancy to fertility, human capital, and labor supply. My results suggest that increases in life expectancy reduce fertility, increase education, and increase labor force participation. Overall, my empirical results suggest that in sub‐Saharan Africa, increases in life expectancy will have a positive impact on growth through fertility, education, and labor supply but that the effect will be small. My results also rule out the possibility that recent shocks to adult mortality in high HIV prevalence countries will reduce fertility, increase labor productivity, and lead to faster growth.     

Wage–productivity differentials and Indian economic efficiency

A frontier-general equilibrium analysis with skill transformation evaluates the productivities of skilled and unskilled labor and potential of the Indian economy. We compare the wages of skilled and unskilled labor between 1994 and 2002 with their respective productivities over this period. Education is considered to be responsible for the skill formation over this period: the change in skilled labor supply is endogenous in the model. Compared to its productivity, skilled labor is underpaid in the initial period and overpaid in the second period. Unskilled labor is underpaid in both periods. A decomposition exercise shows that skilled labor gains from free trade, and stands to lose due to education and domestic competition in the second period. The annualized rate of return to education is between 7 and 10%. The economy operates below its potential in both periods, particularly in the second—due to trade limitations and the failure to capture the return to education. Service sectors are found to have potential to grow significantly.     

COMPARING PER CAPITA INCOME IN THE HELLENISTIC WORLD: THE CASE OF MESOPOTAMIA

Until quite recently, GDP growth between ca. 1 ce and the late Middle Ages was considered non‐existent or even negative. Recently, largely on account of increasing interest in historical national accounting, the late‐medieval figures have been revised upward, in line with an upward adjustment in the estimated shares of manufacturing and pasture. Leaving GDPs dating from the ancient world unaltered would consequently generate figures indicating increased economic growth during the first millennium ce . A considerable number of studies of the late‐medieval period (the object of increasing attention on the part of specialists in early economic history) have caused estimates for the ancient one to be revised upwards, essentially leaving estimates of the changes in economic development over time unaltered. These studies, however, have focused on the Roman Empire and Italia while there is a consensus in the literature that it was quite unrepresentative of all ancient societies with its relatively high share of GDP from the manufacturing sector of the economy. We therefore estimate a new per capita income for another contemporary agrarian society: ancient Mesopotamia. In addition, by examining manufacturing and pasture—the two main reasons for higher income which have been identified in the literature—we have found a tentative explanation for the fact that ancient Mesopotamia's per capita income deviated from that of Rome.     

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.     

Relation between growth and unemployment in a model with labor-force participation and adverse labor institutions

Based on labor search models with an exogenous labor force, existing papers have found a negative relation between long-run economic growth and unemployment. Motivated by the fact that the labor force participation has changed substantially across OECD countries, this paper revisits the long-run relation by taking account of endogenous labor-force participation. We find that, via the effects on employment, changes in labor market institutions may increase or decrease long-run economic growth. Moreover, depending upon the effects on the labor force and employment, these labor market institutions may increase or decrease unemployment rates in the long run. Thus, changes in labor market institutions lead to a non-monotone relation between long-run economic growth and unemployment that is consistent with the data.     

MIGRATION, UNEMPLOYMENT, AND WAGES: THE CASE OF THE CALIFORNIA SAN JOAQUIN VALLEY

The California San Joaquin Valley labor market appears to be at odds with basic economic principles in the sense that despite higher unemployment rates and lower wages, it has continually attracted an influx of in‐migrants, domestic and international. By examining county‐level data for the last two decades, the analysis in this paper is built around two main questions. First, in what proportion does local employment growth reduce local unemployment, increase labor force participation and attract outsiders who will likely take the newly created jobs? Second, to what extent regional migration rates respond to regional relative wages and unemployment differentials? Both questions aim to gain a better understanding of the San Joanquin Valley labor market and the migrants’ decisions to move there, which might shed light in the design and implementation of development policies aimed at reducing unemployment. Results provide evidence that market forces alone are insufficient to correct regional unemployment disparities. Three main findings are offered. First, in‐migrants workers fill most of the newly created jobs. Second, migration seems unresponsive to the unemployment level but responsive to changes in farm income. Third, migration is sensitive to government‐based benefits, property crime rates and housing prices. (JEL R11, R23, R58)
