Tax Reform,Structural Unemployment and the Environment

The effects of environmental tax reform, i.e., using the proceeds of a higher energy tax rate to lower the labour tax rate, on wage formation, employment and environmental quality are analysed in the context of a small open economy with structural unemployment caused by hiring costs. We find that such a reform may boost employment if it shifts the tax burden away from workers towards those without employment in the formal sector. Environmental tax reform succeeds in shifting the tax burden away from workers in the formal sector if higher energy taxes reduce earnings in the informal sector by reducing labour productivity.     

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.     

Labour mobility during transitionEvidence from Georgia1

This article deals with labour mobility in Georgia during economic transition. We use quarterly 1998–99 panel data to examine mobility across six labour market statuses (inactivity, unemployment, formal wage employment, informal wage employment, self‐employment and farming). Our findings are consistent with the hypothesis of labour market segmentation. Formal employment is preferred to informal employment. Unemployment is largely a queuing device for individuals with higher education waiting for formal jobs. Some self‐employment is subsistence activities and consistent with a segmented labour market, while other is high risk and potentially high return activities. Age, gender and education are significant determinants of labour mobility. Finally, informal employment serves as a buffer in times of recession – with farming and informal wage employment absorbing labour shed by other statuses during the Russian financial crisis.     

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.     

Are Minimum Wages to Blame for Informality in the Labour Market?

The paper estimates the impact of the minimum wage on formal and informal employment in a developing country combining the use of aggregate time series data with modern time-series methods. The analysis is carried out for the case of Brazil over the period 1982–2002. The hypothesis under investigation is that minimum wage rises price workers out of the formal labour market and into the informal sector. The modelling strategy involves the estimation of the long-run structure as well as the short-term dynamics of employment equations in which the minimum wage enters as an explanatory variable.JEL codes: J23 J51 C32     

Increasing wage dispersion and the changes in relative employment and wages in Mexico's urban informal sector: 1987-1993

This study analyses the role of changes in informal/formal relative employment, wage levels and wage inequality in explaining increasing wage dispersion in Mexico during the 1987–1993 period. From 1987 to 1993, the variance of the log of hourly wages for Mexican workers increased by more than 50 per cent. Using data from the Encuesta nacional de empleo urbano we find that this increase in the overall wage dispersion was mainly driven by increasing wage dispersion in the formal sector coupled with a faster growth in formal sector employment as a percentage of total employment. However, compression in the distribution of wages within the informal sector contributed to substantially slowdown the increasing overall wage inequality. About 60 per cent of the 1987–1993 4.65 percentage point reduction in the informal sector share of total employment is explained by changes in the structure that determines sectoral employment; the rest is explained by changes in the composition of the labour force, particularly increases in the sectoral education gap and a change in the regional relative share of sectoral employment. Also, from 1987 to 1993 the sectoral wage ratio increased from 0.59 to 0.63. It seems that a relative improvement in unobserved skills in the informal sector helped to close the wage differential but this effect was partially offset by an increase in the relative prices of both observed and unobserved skills, as well as increases in relative observed skills in the formal sector, particularly education.     

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 commodity taxation in the presence of unemployment

In this paper, we evaluate the impact of commodity tax competition on welfare and employment under the destination and origin principles, when the labor market is imperfectly competitive owing to a binding fixed wage. Our main finding is that commodity taxation causes an employment externality whose signs may be opposite under the two principles. While tax competition leads to inefficient tax rates under both principles, we also prove that the origin principle guarantees lower unemployment and higher welfare when the fixed wage is high. Finally, we show that the employment externality still exists in a standard union model of wage determination.     

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.     

A note on the shadow wage in LCDs with migration and formal and informal urban sectors

Given induced rural-to-urban migration, the social cost of (unskilled) labour for urban public sector projects is shown to be lower than the formal-sector, exogenously-determined wage. This result is valid not only when the urban alternative to formal employment is unemployment but also (and more realistically) when the relevant alternatives are formal employment, informal employment and unemployment.     

Cross‐Subsidies,and the Elasticity of Informality to Social Expenditures: The Case of Mexico's Seguro Popular

How is the size of the informal sector affected when the distribution of social expenditures across formal and informal workers changes? How is it affected when the tax rate changes along with the generosity of these transfers? In our search model, taxes are levied on formal‐sector workers as a proportion of their wage. Transfers, in contrast, are lump‐sum and are received by both formal and informal workers. This implies that high‐wage formal workers subsidize low‐wage formal workers as well as informal workers. We calibrate the model to Mexico and perform counterfactuals. We find that the size of the informal sector is quite inelastic to changes in taxes and transfers. This is due to the presence of search frictions and to the cross‐subsidy in our model: for low‐wage formal jobs, a tax increase is roughly offset by an increase in benefits, leaving the unemployed approximately indifferent. Our results are consistent with the empirical evidence on the recent introduction of the “Seguro Popular” healthcare program.     

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.     

Wage and employment effects of a wage norm

Most transition countries used tax‐supported wage norms in the early 1990s, as a part of their market liberalization programmes. This article analyses how a firm‐level tax (or subsidy) on deviations from a pre‐set wage norm may promote employment by rotating the labour demand curve perceived by the workers’ union around the value of the norm. We derive the conditions under which it yields a positive employment effect. We test the effect of the norm on the wages on a sample of Polish firms in 1990 and 1991. The data support the role of the wage norm on the position of the perceived labour demand curve and the role of the tax rate on its slope.     

Compulsory Superannuation and Labour Market Responses

Compulsory contributions to superannuation have significant second round effects on labour market outcomes. The effects of employer, employee and government contributions are compared and contrasted for markets with different degrees of wage flexibility. With a flexible wage, the market wage adjusts to offset most of the initial effects of the superannuation levies. However, compulsion means that many employees perceive the present value of the future retirement income to be less than the levy. The levies as a form of tax on labour lead to lower overall remuneration for employees and lower employment     

Determinants of wage stickiness in a developing economy

We explore wage flexibility in a developing country and compare our results to what has been found in similar studies using European data. In particular, we conduct a survey of 1189 firms in Pakistan to analyze the determinants of wage rigidity. We find that the existence of competitive wages and an interaction with the informal economy are statistically significant determinants of wage stickiness. While the role of competitive wages is similar to what has been found in studies of European firms, the latter find a much larger role for turnover, collective bargaining and employment protection. In contrast, in Pakistan we find that firms hiring from the informal sector are significantly more flexible in changing their wages. This suggests that the informal sector adds to the wage flexibility of the formal sector.     

Economic liberalization, capital mobility and informal wage in a small open economy: A theoretical analysis

Empirical evidence suggests that the size of the informal sector in the developing countries has increased considerably during the liberalized economic regime. The present paper purports to analyze the consequences of economic reforms on the wellbeing of the informal sector workforce using a three-sector general equilibrium model with two informal sectors. The theoretical analysis finds that different liberalized policies produce diverse effects on the informal wage and that these results are independent of the nature of capital mobility between the informal and the formal sectors. It also shows that labour market reforms, contrary to the common wisdom, are likely to produce favourable effects on the informal wage.     

Consequences of Environmental Tax Reform for Unemployment and Welfare

We investigate the welfare effects of environmental tax reform, i.e. raising environmental taxes and using the proceeds to reduce distortionary taxes on labour. The framework of analysis is a small open economy with involuntary unemployment due to a rigid consumer wage. Environmental tax reform boosts not only environmental quality but also employment if substitution between labour and resources is easy, the production share of the fixed factor is large, and the initial tax rates on resources and profits are small. If the initial tax system is sub-optimal with a negligible tax on resources, profits rise as well.     

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.     

Flat income taxation,redistribution and labour market performance

A flat tax rate on labour income has gained popularity in European countries. This article assesses the attractiveness of such a flat tax in achieving redistributive objectives with the smallest distortions to employment. We do so by using a detailed applied general equilibrium model for the Netherlands. The model is empirically grounded in the data and encompasses decisions on hours worked, labour force participation, skill formation, wage bargaining between unions and firms and a wide variety of institutional details. The simulations suggest that the replacement of the current tax system in the Netherlands by a flat rate will harm labour market performance if aggregate income inequality is contained. Only flat tax reforms that reduce redistribution will raise employment. This finding bolsters the notions from optimal tax literature regarding the equity-efficiency trade off and the superiority of nonlinear taxes to obtain redistributive goals in an efficient way.     

Informality and mobility

Informality is a defining characteristic of labour markets in developing and transition countries. This paper analyzes patterns of mobility across different forms of formal and informal employment in Russia. Using the Russian Longitudinal Monitoring Survey household panel we estimate a dynamic multinomial logit model with individual heterogeneity and correct for the initial conditions problem. Simulations show that structural state dependence is weak and that transition rates from informal to formal employment are not lower than from non-employment. These results lend support to the integrated view of the labour market.
