Economic reform and informal wage—a general equilibrium analysis

We attempt to trace the consequences of liberal economic policies on informal wage in a general equilibrium model with formal informal labor markets, wage-differential, vertical linkage and restricted capital movement. In particular, we show that the informal wage, representing income for a vast segment of unskilled labor may actually increase even if more people are employed in the informal segment. This also confirms that a contraction in the formal sector employment and the consequent expansion in the informal segment do not necessarily imply impoverishment of the existing set of informal workers.     

No education,no good jobs? Evidence on the relationship between education and labor market segmentation

This paper assesses labor market segmentation across formal and informal salaried jobs and self-employment in three Latin American and three transition countries. It looks separately at the markets for skilled and unskilled labor, inquiring if segmentation is an exclusive feature of the latter. Longitudinal data are used to assess wage differentials and mobility patterns across jobs. To study mobility, the paper compares observed transitions with a new benchmark measure of mobility under no segmentation. It finds evidence of a formal wage premium relative to informal salaried jobs in the three Latin American countries, but not in transition economies. It also finds evidence of extensive mobility across these two types of jobs in all countries, particularly from informal salaried to formal jobs. These patterns are suggestive of a preference for formal over informal salaried jobs in all countries. In contrast, there is little mobility between self-employment and formal salaried jobs, suggesting the existence of barriers to this type of mobility or a strong assortative matching according to workers’ individual preferences. Lastly, for both wage differentials and mobility, there is no statistical difference across skill levels, indicating that the markets for skilled and unskilled labor are similarly affected by segmentation.     

Transitions across labor market states including formal/informal division in Egypt

This study examines the worker transitions across labor market states including formal/informal division using panel data of 2006 to 2012 from Egypt. We generate a broad set of facts about labor market dynamics in Egypt. We first develop transition probabilities by gender across different labor market states including formal/informal sectors utilizing Markov transition processes. Government employment is the most persistent labor market state for both men and women and the out of labor force is the second most persistent labor market state for women. Unemployment is the most mobile labor market state. Informal private wage work and self‐employed–agriculture are also relatively mobile labor market states. We next identify the effects of individual, household and job characteristics on different mobility patterns by estimating multinomial logit models. We find that gender, age, education, experience, and several sectors of economic activity are associated with the transition probabilities between the labor market states considered such as formal wage, informal wage, self‐employment, unemployment, government employment, and out of labor market. Education, in particular, university degree or above is noted to play a vital role in the probability of transitions across several labor market states.     

International factor mobility,informal interest rate and capital market imperfection: A general equilibrium analysis

This paper makes an attempt to provide a theory of determination of interest rate in the informal credit market in a less developed economy in terms of a three-sector static deterministic general equilibrium model. There are two informal sectors which obtain production loans from a monopolistic moneylender and employ labour from the informal labour market. On the other hand, the formal sector employs labour at an institutionally fixed wage rate and takes loans from the competitive formal credit market. We show that an inflow of foreign capital and/or an emigration of labour raises (lowers) the informal (formal) interest rate but lowers the competitive wage rate in the informal labour market when the informal manufacturing sector is more capital-intensive vis-à-vis the informal agricultural sector. International factor mobility, therefore, raises the degrees of distortions in both the factor markets in this case.     

The formal sector wage premium and firm size

We show theoretically that when larger firms pay higher wages and are more likely to be caught defaulting on labor taxes, then large-high wage firms will be in the formal and small-low wage firms will be in the informal sector. The formal sector wage premium is thus just a firm size wage differential. Using data from Ecuador we illustrate that firm size is indeed the key variable determining whether a formal sector premium exists.     

Informality,public employment and employment protection in developing countries

This paper proposes an equilibrium matching model for developing countries’ labor markets where the interaction between public, formal private and informal private sectors are taken into account. Theoretical analysis shows that gains from reforms aiming at liberalizing formal labor markets can be annulled by shifts in the public sector employment and wage policies. Since the public sector accounts for a substantial share of employment in developing countries, this approach is crucial to understand the main labor market outcomes of such economies. Wages offered by the public sector increase the outside option value of the workers during the bargaining processes in the formal and informal sectors. It becomes more profitable for workers to search on-the-job, in order to move to these more attractive and more stable types of jobs. The public sector therefore acts as an additional tax for the formal private firms. Using data on workers’ flows from Egypt, we show empirically and theoretically that the liberalization of labor markets plays against informal employment by increasing the profitability, and hence job creations, of formal jobs. The latter effect is however dampened or even sometimes nullified by the increase of the offered wages in the public sector observed at the same time.     

Informal pay gaps in good and bad times: Evidence from Russia

Informal work is traditionally large in Russia and has further increased in the recent years. We explore the implications of this shift in terms of wage dynamics. Our characterization is based on the estimation of informal pay gaps at the mean and along the wage distribution, relying on the Russian Longitudinal Monitoring Survey for 2003–2017. Our approach comprises three original features: we rely on unconditional quantile effects of informality, we incorporate quantile-specific fixed effects using a tractable approach, and we suggest a treatment of the incidental parameter bias. Over the whole period, informal wage penalties are relatively small and do not suggest heavily segmented labor markets, even at low wage levels. Yet, in the past decade, a substantial negative selection into informal employment and self-employment has taken place, on average and especially at low earnings. Economic downturns and labor market policies have likely contributed to the shakeout of less productive workers in the formal sector, making the low-tier informal sector more of a last resort.     

Economic transition and gender differentials in wages and productivity: Evidence from Chinese manufacturing enterprises

We use firm-level data to analyze male–female wage differences in Chinese industry in the late 1990s. Our estimates indicate that employers' discrimination against women was not a significant source of the gender wage gap in Chinese state-owned enterprises. Instead, we find that the relative wage of unskilled female to male workers was higher than their relative productivity. This result indicates that unskilled female workers in the state sector had historically received wage premiums and consequently accounted for a disproportionate share of the sector's labor surplus.     

The Male-Female Pay Gap Driven by Coupling between Labor Markets and Mating Markets

Synopsis Males often get paid more than females for the same work. This male-female pay gap has been observed throughout the world over many years. The most commonly cited explanations focus on gender oppression and workplace discrimination. We agree that discrimination contributes significantly to the pay gap; however, other factors may play important roles in how the sexes compete in the labor market. We use observations from psychology and concepts from biology to show how aspects of mate choice may influence labor markets. With a mathematical model, we analyze how mating preferences for partner wages affect the differences in wages between males and females, and in turn how wage differences affect mating preferences. If some extrinsic force, such as discrimination, creates an initial bias in wages, then coupled feedback between mating preferences and wages creates and maintains excess mating preference and wage biases. This model demonstrates how coupling between labor markets and mating markets can lead to outcomes that do not occur when analyzing either market in isolation from the other.     

Gender-Based Occupational Choices and Family Responsibilities: The Gender Wage Gap in Italy

This paper explores the relationship between the gender division of labor, occupational choices, and the gender wage gap in Italy. In Italy, cultural factors and low availability of formal childcare services define gender roles that are generally based on the male breadwinner model, in which childcare is almost completely entrusted to women. The analysis is carried out through an extension of the Oaxaca–Blinder decomposition and is based on data from the 2007 Italian National Institute for Workers’ Professional Development (ISFOL). The results are consistent with gender discrimination on wages and suggest that women’s occupational paths are often an outcome of limited choices, and that women’s unpaid domestic work negatively interferes with the energy women can put into paid work. These findings support the need to ensure gender equality in and out of the labor market, especially through deep changes in Italian social norms and through the development of formal childcare.     

Educational Attainment and the Gender Wage Gap: A Comparison of Young Men and Women in 1984 and 2007

This study pools data from two sources to investigate the role of educational attainment in determining the gender wage gap. The empirical analysis reveals that the returns to education remained largely unchanged for young men but declined significantly for young women over the period 1984–2007. We find significant evidence of a decline in the returns to a Bachelor's degree for young women as well as evidence of increasing wage inequality over time among young men and women with a Bachelor's degree. Also, in 2007, the gender wage gap between young men and women was largest for those with a Bachelor's degree. Further, our analysis suggests that young women with a college education may confront more discrimination in the labor market than young women without a college education. We conclude that promoting educational attainment among young women may be a necessary but not sufficient condition for addressing the gender wage gap.     

Why should Southern economies stay in the Euro Zone? The role of labor markets

We assume a world of two countries in a fixed exchange rate system. These countries differ in the features of their labor markets. The home country is characterized by a dual labor market, with formal and informal sectors. In the foreign country, a nominal wage rigidity exists. In this context, the situation of the labor markets in each country is not optimal owing to a misallocation of workers between sectors in the domestic economy and unemployment in the foreign economy. We show that a devaluation of domestic currency implies a fall in production in each country and deterioration of labor markets in both countries.     

Informal Employment and the Structure of Wages in India: A Review of Trends

The “alternative”, “atypical” or “informal” workforce has grown in developed and developing countries alike. One of the more recent evolutions of informal employment has been of informal employment within formal enterprises. In the interest of flexibility and cost‐reduction, many formal firms increasingly resort to hiring workers on a temporary or informal basis. Alongside, and perhaps, as a result of the persistence and pervasiveness of informal employment, issues relating to inequality have come to the fore. This paper is motivated by these two intertwining aspects of Indian labor market—informality and wage inequality. Using nationally representative sample data, the paper examines trends in wage inequality among various forms of informal workers, overlaying these findings with broader trends in inequality. Using a regression based inequality decomposition, the paper compares the sources of wage inequality across different employment groups and the reasons for differences in wage inequality.     

Job search and mobility in developing countries. Theory and policy implications

A labor market model is developed in which the formal sector is characterized by search frictions whereas the informal sector is competitive. We show that there exists a unique steady-state equilibrium in this dual economy. We then consider different policies financed by a tax on firms' profits. We find that reducing the unemployment benefit or the firms' entry cost in the formal sector induces higher job creation and formal employment, reduces the size of the informal sector but has an ambiguous effect on wages. We also find that an employment/wage subsidy policy and a hiring subsidy policy have different implications. In particular, the former increases the size of the informal sector while the latter decreases it.     

Sex Differentials in Earnings in the South Korean Labor Market

We examine gender differences in earnings among South Korean workers in 1988 – the year the South Korean National Assembly enacted the Equal Employment Opportunity Act. Using the "88 Occupational Wage Bargaining Survey on the Actual Condition," we calculate women's mean earnings as a percentage of men's mean earnings by major industrial category and educational attainment. We find a larger wage gap among clerical and sales workers than production workers or professionals. Generally, the more education a woman has, the smaller the gap between her earnings and those of her male counterparts. Women with a middle-school education have a mean income 53.5 percent that of comparable men, while the female-to-male wage ratio among college graduates is 76.1 percent. We analyze wage differences separately for women and men. Following Ronald Oaxaca's (1973) work, we decompose male–female wage differentials. We also calculate a discrimination coefficient. Our work shows that, all else equal, men earn from 33.6 percent to 46.9 percent more than women with comparable skills. We attribute the difference to gender discrimination.     

Are labor markets segmented in developing countries? A semiparametric approach

We test the hypothesis that observably similar workers earn higher wages in the formal sector than in the informal sector in developing nations. Using data from Argentina's household survey and various definitions of informal employment, we find that on average, formal wages are higher than informal wages. Parametric tests suggest that a formal premium remains after controlling for individual and establishment characteristics. However, this approach suffers from several econometric problems, which we address with semiparametric methods. The resulting formal premium estimates prove either small and insignificant, or negative. Neither do we find significant differences in measures of job satisfaction between the two sectors. We invoke these results to question the mainstream view that labor markets are segmented along formal/informal lines in developing nations such as Argentina.     

Informal employment relationships and the labor market: Is there segmentation in Ukraine?

One of the most important factors that determine individuals’ quality of life and wellbeing is their position in the labor market and the type of jobs that they hold. When workers are rationed out of the formal segment of the labor market against their will, i.e., the labor market is segmented, their quality of life is limited, and their wellbeing is reduced. When they can freely choose between a formal or informal employment relationship, i.e., the labor market is integrated, their wellbeing can reach high levels even in the presence of informal employment. We, therefore, test whether the Ukrainian labor market is segmented along the formal-informal divide, slicing the data by gender and age. The analysis that we perform consist in the analysis of short-term and medium-term transitions between five employment states, unemployment and inactivity. We also analyze wage gaps of mean hourly earnings and across the entire hourly earnings distribution, controlling for time-invariant unobserved heterogeneity. According to our results segmentation is present for dependent employees: for a large part of informal employees informal employment is used as a waiting stage to enter formal salaried employment and is not voluntarily chosen. As far as self-employment is concerned the evidence is mixed regarding segmentation in the Ukrainian labor market. This heterogeneity in outcomes implies that not all informal work is associated with a low quality of life and reduced wellbeing in post-transition economies.     

Effects of Marriage, Education and Occupation on the Female / Male Wage Gap in China

In the present study the way in which the gender wage gap in urban China differs according to marital status, education and occupation, is examined. Married Chinese women experience much larger absolute gender wage gaps than their unmarried counterparts. The proportion of the gender wage gap unexplained by differences in the levels of productive characteristics is also higher for married women than single women. Gender wage gaps are smaller for more educated women. These findings suggest that occupational segregation is not as important a factor as industrial segregation in accounting for the gender wage gap in China's urban labour markets.     

Decomposing Gender Wage Differentials Using Quantile Regression: Evidence from the Lebanese Banking Sector

This paper investigates gender pay inequality in the labor market of a developing country. Our empirical investigation uses data derived from a sample of employees in the Lebanese banking sector for the years 2008 and 2014. Using Blinder-Oaxaca decomposition, the results reveal that the unexplained component of the gender wage gap, attributed to discrimination, represents a substantial share of the total gap. A surprising result is that the contribution of human capital to the gender wage gap is negative, suggesting that wage discrimination is the main explanation for the gap. Utilizing the Machado-Mata methodology to decompose the wage gap across the entire wage distribution, our findings indicate that the unexplained component of the raw gender wage gap is more pronounced at the low and middle ranges of the distribution. However, the explained component dominates at the top of the distribution, suggesting that earnings gaps are fully explained by observed characteristics.     

A TEST OF EMPLOYER DISCRIMINATION IN THE NBA

This paper presents a test of an important implication of Becker's theory of employer discrimination: when institutional change enhances labor mobility, employer discrimination falls because it becomes more costly for employers to indulge tastes for discrimination. The test case is the National Basketball Association (NBA). This paper specifically addresses the following question about the NBA: why did black/white player salary differentials vanish by the early 1990s? Previous studies claim that NBA wage gaps in the 1980s are attributable to customer discrimination and monopsonistic wage discrimination. This study argues that employer discrimination was an important source of those gaps and that one reason they vanished was because reduced monopsony power eradicated employer discrimination. Monopsony power fell because the 1988 NBA Collective Bargaining Agreement and the entry of four new teams in the league enhanced player mobility and increased the amount of labor market competition. Using data for the 1985-86 and 1990-91 seasons, employer discrimination was proxied by the race of the team's general manager. Empirical results strongly suggest that a major reason the NBA wage gap vanished in the later period was because of a reduction in employers' ability to discriminate. This is in contrast to earlier literature on the NBA, which has tended to emphasize the role of customer discrimination. (JEL J71)
