On measuring the wealth of nations: the US economy, 1964-2001

This paper examines the methodology of Shaikh and Tonak (Measuringthe Wealth of Nations, 1994) underlying their calculation ofestimates of productive labour in the US economy from 1964 to2001. The focus is not on the results but on the methods thatgenerate them. The paper finds that the compromises made byShaikh and Tonak because of data unavailability are unreliable,and that better approximations are possible. On this latterbasis, the Shaikh and Tonak methodology can be used to providethe labour and wage estimates needed for empirical investigationsin the surplus-based tradition.     

The effect of taxation on labour supply: the case of moonlighting

The authors provide a simple test of supply-side economics by estimating the responsiveness of moonlighting labour supply to changes in the marginal tax rate and the wage rate. While standard theory teachers that changes in taxes and wage should have opposite and equal effects on labour supply, taxes affect the entire asset position of the household. In the short run, an adjustment of hours in the second job may be the only option available to an individual in responding to a tax change. Thus, analyses based on after-tax wages may understate supply-side effects. To estimate these effects a tobit procedure is employed. The empirical results suggest a backward-bending supply curve over thet range of moonlighting hours. Data consist of a subsample of male blue-collar workers from the 1978 cross-section of the Panel study of Income Dynamics.     

Sampling variability: some observations from a labour supply equation

In economics, the number of observations available for empirical work is often predetermined. Researchers assume some large sample distribution and carry through with measurement and testing applied to data sets of varying sizes. The consequences of sampling variability are generally ignored. It is shown in a re-sampling experiment, using data sets of different sizes and estimating log-linear male labour supply equations, that a wide range of what appears to be statistically supported estimates of the wage elasticity of labour supply are generated. Testing based on bootstrapped estimates shows that 4000 observations are required to reduce sampling variability to statistically acceptable levels.     

KEYNES ON WAGE FLEXIBILITY AND THE AUSTRALIAN WAGES SYSTEM*

Keynes' General Theory briefly discusses the Australian wages system, as an example of a system in which an attempt was made to fix real wages by law. Keynes argues that such a system, strictly enforced, generates an unstable unemployment equilibrium or highly volatile money wages and prices. This paper clarifies Keynes' views on the Australian system, with a view to their wider relevance for the significance of real and money wage flexibility and inflexibility in Keynes' economics. The most striking finding is that money wage stickiness is a conclusion, not an assumption, of Keynes' theory of employment.     

Does the labour supply of wives respond to husbands' wages? Canadian evidence from micro data and grouped data

Abstract. Using micro data and grouped data, we assess the extent to which Canadian wives adjusted their labour supply in response to changes in husbands' wages during the period 1980‐2000. Grouped data parameters based on weighted least squares and the unbiased‐error‐in‐variables estimator developed by Devereux (2004, 2007a,b) yield cross‐wage elasticities that are substantially higher (in absolute value) than those derived from OLS regressions run on micro data. Both grouping estimators indicate that the labour supply of Canadian wives responded strongly to changes in husbands' wages during the 1980s. For the 1990s, our estimates of wives' cross‐wage elasticity display greater dispersion.     

Prices,Productivity and Wage Bargaining in Open Economies*

According to the standard union bargaining model, unemployment benefits should have big effects on wages, but product‐market prices and productivity should play no role in the wage bargain. We formulate an alternative strategic bargaining model, where labour and product‐market conditions together determine wages. A wage equation is derived and estimated on aggregate data for four Nordic countries. Wages are found to depend not only on unemployment and the replacement ratio, but also on productivity, international prices and exchange rates. There is evidence of considerable nominal wage rigidity. Exchange rate changes have large and persistent effects on competitiveness.     

The role of unemployment in wage determination: further evidence on the wage curve from Turkey

This paper presents an empirical estimation of the correlation between wages and regional unemployment rates in Turkey, more specifically it explores the role of regional unemployment rates in wage determination. The analysis builds upon a series of recent empirical studies on the wage-unemployment relationship, now commonly known as ‘the wage curve’, a downward sloping curve in wage-unemployment space. The existing studies are for most part in advanced market economies, while this paper presents one of the few attempts at a wage curve analysis within the context of a developing market economy. A cross-sectional estimation of micro level individual wage data for the Turkish labour market in 1994, suggest a statistically significant negative correlation between wages and regional unemployment rates. Separate regressions for men and women, however, show a wage curve to exist only in the male labour market. The study also presents the results on other variables of wage determination such as returns to schooling, returns to age, job tenure, gender, industrial and occupational affiliation of the worker, economic sector and union status.     

The minimum wage and the Lithuanian labour market

This paper presents a comprehensive and non‐standard labour market analysis based on univariate and multivariate models for wages. The novelty of this paper lies in the use of non‐normalized cointegrating vectors for labour market analysis. Wages are the basis of labour market models, as well as the key factor for employees and employers; therefore, the central analytical axis is a classical wage bargaining process, where one side requires and the other side proposes a certain level of wages. Analysis is divided into two parts: foremost, a careful analysis of Lithuanian wages is conducted and a univariate model for the investigation of interactions between the minimum wage and the rest of the wages is proposed; only after the minimum wage model is drafted can the multivarate model for the whole economy be built up. Briefly, the methodology used in this article can be annotated as a synthesis of sequential theoretical and empirical considerations that combine the results of theoretical macroeconomics with data‐generating patterns and stylized facts. The model is considered as the final one only if macro‐theory preconditions, statistical prerequisites, and stylized real‐world requirements are met and fulfilled. In addition, this article gives an example and a quantitatively, as well as qualitatively, motivated suggestion as to how to incorporate minimum wages into econometric models and puts forward an explanation for why it is necessary to include minimum wage dynamics into labour market analysis. The article is nothing but an empirical case study that demonstrates how many minor details have to be taken into account until a realistic labour market model is built up. Although the paper deals with the labour market, the suitable application of time series methods is the main subject of the analysis.     

A dynamic spatial panel data approach to the German wage curve

A wage curve is a decreasing function of wages on the regional unemployment rate. Most empirical studies on the wage curve ignore possible spatial interaction effects between the regions which are the primary units of research. This paper reconsiders the western German wage curve with a special focus on the geography of labour markets. Spillovers between regions are taken into account. The paper tests whether the unemployment rate in the larger surrounding region also affects wages. In addition, agglomeration effects and effects of local monopsony are assessed.The main database is a random sample of 974,179 employees observed over the period 1980-2004 and covering 326 NUTS3 units (districts). This rich data set is used to estimate a dynamic wage curve according to the two-step approach of Bell et al. (2002). In the first step one controls for individual heterogeneity and in the second step one allows for spatial effects of unemployment across regions on wages. We check the sensitivity of this wage elasticity to various spatial weight matrices as well as allowing for the endogeneity of unemployment. We also estimate the wage elasticity for various population groups.     

Real wage determination in Bangladesh agriculture: An econometric investigation

Thsi paper develops and estimates a real wage model for the agricultural sector in Bangladesh for the period 1973:2–1985:4. The model is developed within the framework of the market theory of labour demand and labour supply. The empirical results are supportive of the market theory of wages.     

Causal Relationships in Australian Wage Inflation and Minimum Award Rates*

When variables are correlated in time-series studies, it is often difficult to determine which is cause and effect, and in what sense. This paper applies multivariate time-series tests of causality to Australian wage, price, minimum wage award, labour demand and strike (working days lost) variables for 1953-76. The results provide tentative support for a model in which strikes are exogenous:the size of Arbitration Commission awards is determined by strikes (suggesting that a trade union capture theory of Arbitration Commission regulation may apply):money wages are determined by minimum wage awards; and the demand for labour variable (measured in this paper by the ratio of actual to potential output) is determined (in a negative relationship) by money wages.     

The responsiveness of industry wages to low‐frequency shocks in Canada

Abstract The first objective of this paper is to examine the empirical relationship between low‐frequency shocks to labour demand and average wages on an industrial basis using a Canadian longitudinal data set. We estimate a fixed‐effects model that controls for workers’ unobservable attributes. The second major objective is to extend the existing industry‐based literature by estimating a specification allowing for a comparison between the degree of wage responsiveness of within‐firm stayers and between‐firm movers. The findings indicate that average wages by industry tend to respond positively to low frequency changes in employment, and that there is some degree of wage flexibility within firm‐worker matches.     

Is Downward Wage Flexibility the Primary Factor of Japan's Prolonged Deflation?

By using both macro‐ and micro‐level data, this paper investigates how wages and prices evolved during Japan's lost two decades. We find that downward nominal wage rigidity was present in Japan until the late 1990s, but disappeared after 1998 as annual wages became downwardly flexible. Moreover, nominal wage flexibility may have contributed to Japan's relatively low unemployment rates. Although macro‐level movements in nominal wages and prices seemed to be synchronized, such synchronicity is not observed at the industry level. Therefore, wage deflation does not seem to be a primary factor of Japan's prolonged deflation.     

Skilled and unskilled wage dynamics in Italy in the 1990s: changes in individual characteristics,institutions, trade and technology

In this paper, we use individual micro data on workers combined with industry and regional data to study the wage dynamics of skilled and unskilled workers in Italy in the 1991–1998 period. In contrast to previous empirical studies, our data make it possible to analyse, within a single framework, the role of many of the factors indicated in the literature as possible determinants of skilled and unskilled wage dynamics: changes in the individual characteristics of workers, changes in labour market institutions, increasing international integration, and skill‐biased technological progress. Our results show that international integration, both in terms of trade in goods and in terms of international labour mobility, plays a role in determining the wage dynamics of skilled (white‐collar) and unskilled (blue‐collar) workers. Moreover, in line with labour economics research, our findings show that the individual characteristics of workers and the institutional variables are more relevant in explaining skilled and unskilled wage dynamics than wage differentials.     

Wage and price determination in a labour-exporting economy: The case of Ireland

A model designed to incorporate external influences through the labour and goods markets on the rates of domestic wage and price inflation is specified and estimated from postwar Irish data. It consists of equations explaining the rate of change of prices, migration, the supply of labour, the rate of change of wages and three identities. The model is both simultaneous and nonlinear, and an appropriate modification of the two-stage least-squares estimation technique is used. The estimated equations explain between 71 percent and 84 percent of the variance in the dependent variables. Since two of these are proportionate first differences, the remaining two a ratio and a first difference, this might be deemed satisfactory. However, some of the individual coefficient estimates are not.     

Wage Determination In Australia*

This paper examines whether a stable expectations-augmented Phillips curve exists for Australia. High real wages in the face of continuing high unemployment over the past decade have led to suggestions that the level of unemployment has little effect on wage determination, with the bargaining process taking place between employers and those employees in ‘secure employment’. Results from aggregate data suggest that the level of unemployment is relevant to wage determination. In addition, the impact of overtime on the growth in money wages is consistent with the view that those in secure employment are influenced by labour market conditions.     

Liberalization and the Changing Inter‐industry Wage Structure of the Organized Manufacturing Sector in India, 1973/74–2003/04

This paper examines the inter‐industry wage structure of the organized manufacturing sector in India for the period 1973/74–2003/04 by estimating the growth of average real wages for production workers by industry. Using wage data on 51 three‐digit industries, our estimation procedure obtains estimates of growth of real wages per worker that are wholly deterministic in nature by accounting for any potential structural break(s) associated with the reforms. Our paper identifies three distinct regimes—pre‐reform, first phase reforms and second phase reforms, over which real wages have grown at varying rates for each industry. Our findings suggest that the inter‐industry wage differences have become more pronounced in the post‐reform periods. The paper provides new evidence from India on the need to consider seriously the hypothesis that industry affiliation is potentially an important determinant of wages when studying any relationship between reforms and wages.     

Wages and wage growth in Poland: The role of foreign direct investment

In recent years Poland has received substantial inflows of foreign direct investment. This paper combines detailed labour market data with industry data from the Polish manufacturing sector to examine the effects of foreign direct investment inflows on wages and wage growth. The empirical evidence we assemble suggests that workers in industries with greater foreign presence enjoy higher wages and higher wage growth. This effect appears to be robust to a variety of empirical approaches, estimation techniques and specification checks.

Real wage cyclicality in the Eurozone before and during the Great Recession: Evidence from micro data

We study the response of real wages to the business cycle in eight major Eurozone countries before and during the Great Recession. Average real wages are found to be acyclical, but this reflects, in large part, the effect of changes in the composition of the labour force related to unemployment variations over the cycle. Using longitudinal micro data from the ECHP and SILC panels to control for composition effects, we estimate the elasticities of real wage growth to unemployment increases between −0.6 and −1 over the period 1994–2011. Composition effects have been particularly large since 2008, and they explain most of the stagnation or increase in the average wage observed in some countries from 2008 to 2011. In contrast, at a constant labour force composition in terms of education and experience, the figures indicate a significant decrease in average wages during the downturn, particularly in countries most affected by the crisis. Overall, there is no evidence of downward nominal wage rigidity during the Great Recession in most countries in our sample.     

Dynamic factor models of consumption,hours and income

This paper addresses two questions in the economics of intertemporal choice. First, what are the key factors that drive fluctuations in income and what are the time paths of their effects? Second, how do consumers respond to these factors? We answer these questions by estimating dynamic factor models of consumption, hours, wages, unemployment, and income that account for measurement error and the fact that variables used in the study are measured at different time intervals and/or are aggregates for the calendar year. We pay special attention to a dynamic factor representation of a joint life cycle model of consumption and labour supply, which permits us to quantify the effect of wages, unemployment, and other factors on the marginal utility of income as well as to estimate the substitution effects of wage changes on labour supply and consumption.
