Variable labour supply, specialisation-based external economies, and capital inflow

This paper examines the impact of exogenous capital inflow on prices, production, labour supply, and welfare in the presence of specialisation-based externalities. The paper utilises a simple model of an economy that produces one-final good by means of capital, labour, and a large number of varieties of an intermediate good. The intermediate good is produced by means of capital and labour. The supply of capital is exogenous but the supply of labour is endogenous. The presence of internal economies of scale in the intermediate good industry gives rise to specialisation-based external economies in the production of the final good. Perfect competition prevails in the final good industry whereas the intermediate good industry operates under Chamberlinian monopolistic competition. It is shown that exogenous capital inflow decreases labour supply and increases welfare only if the elasticity of substitution between leisure and the final good is equal to or less than unity. The paper also shows that, if trade opens up between two otherwise similar economies, a capital rich country would be a net importer of varieties of the intermediate good.     

The determinants of female labour supply in Hungary

The aim of this paper is to closely examine the effect on a married woman's labour supply decision of non-labour income and of her own wage rate in a transition economy. The paper first shows that labour force participation rates for Hungarian females, though decreasing, were still extremely high and comparable to male economic activity in western countries. It then estimates labour supply parameters using a model that controls for sample selection issues associated with the labour supply of married women. Wage elasticity is estimated to be high and positive (1.81) while the income effect is consistent with leisure being a normal good. No sample selection bias is found.     

Self-insurance in a life-cycle model of labour supply and savings

This paper analyses the incentives to work and to save over the life cycle in the presence of incomplete markets. In a calibrated, partial equilibrium model, flexibility in hours worked changes asset age-profiles: borrowing when young is greater and saving when middle-aged is greater than when labour supply is fixed. Uncertainty causes individuals to work longer hours and to consume less when young. With flexibility over hours, accumulating precautionary assets incurs less of a utility cost and so the level of saving is greater. Further, allowing for flexibility and uncertainty means simulated hours of work and consumption more closely match the age profiles in the data.     

Real wages,inflation and labour productivity in Australia

This article presents an analysis of real wages, inflation and labour productivity interrelationships using cointegration, Granger causality and, most importantly, structural change tests. Applications of tests to Australian data over the 1965 to 2007 period corroborate the presence of a structural break in 1985 and show that a 1% increase in manufacturing sector real wages led to an increase in manufacturing sector productivity of between 0.5% and 0.8%. Comparable estimates for the effect of inflation on manufacturing sector productivity have limited statistical significance. Granger causality test results suggest that real wages and inflation both Granger cause productivity in the long run.     

Farm income,market wages,and off-farm labour supply

In most developed countries we observe an increasing share of part-time farming at the expense of full-time farmers. In the present paper, we develop a theoretical labour supply model which accounts for the specific decision problem of a farmer. The empirical analysis uses the ordered probit and a Tobit model to explain labour supply behaviour for a sample of farm households in Upper Austria. Farm size, household characteristics, as well as education significantly influences off-farm labour supply behaviour. The obtained wage elasticities for male farmers are comparable in magnitude to those obtained in labour supply studies for adult females or elderly people.

Zusammenfassung Nebenerwerbslandwirtschaft entwickelt sich immer mehr zur vorherrschenden Form der Erwerbstätigkeit von Landwirten. Die Erwerbsentscheidung zwischen Voll-, Zu- und Nebenerwerb wird im Rahmen eines statischen Arbeitsangebotsmodells untersucht und mit Hilfe eines Ordered-probit-bzw. eines Tobit-Ansatzes für 1.842 landwirtschaftliche Haushalte in Oberösterreich getestet. Das Arbeitsmarktverhalten von Landwirten ist gekennzeichnet durch eine hohe Lohnelastizität vergleichbar den Ergebnissen für das Erwerbsverhalten von Personen auf dem sekundären Arbeitsmarkt. Darüber hinaus läßt sich ein signifikanter Einfluß der Betriebsgröße, der Struktur des landwirtschaftlichen Haushaltes sowie der Art und des Umfangs der Ausbildung des Betriebsleiterehepaares erkennen.

Multi-family households in a labour supply model: a calibration method with application to Poland

Models of cooperative and noncooperative behaviour opened the household ‘black box’ and allowed for individual treatment of partners in couples. However, labour supply literature has so far largely ignored a broader issue – the distinction of single versus multi-family (‘complex’) households. We propose a method to account for multi-family household structure by borrowing from recent applications of the collective model to identify the degree of sharing. We assume that each household is characterized by a between-family sharing parameter, which is calibrated on estimated preferences, observed labour market status and other characteristics. We apply the method to Polish labour market data.     

And the winner is... An empirical evaluation of unitary and collective labour supply models

An empirical evaluation is presented of two competing flexible labour supply models. The first is a standard unitary model, while the second is based on the collective approach to household behaviour. The evaluation focuses on the testing of the model’s? theoretical implications and on their ability to identify structural information, like preferences and the intrahousehold allocation process. Models are applied to Dutch microdata from the DNB Household Survey. The unitary model cannot be rejected for male and female singles, while it is rejected for a sample of couples. The alternative collective model cannot be rejected for the same sample, allowing identification of individual preferences and an intrahousehold sharing rule that can be used as a basis for welfare economic policy evaluations.     

The role of labour demand elasticities in tax incidence analysis with heterogeneous labour

Whether labour bears full burden of household level income and consumption taxes ultimately depends on the degree of substitutability among different types of labour in production. We find more variation in incidence patterns across households with less than perfectly substitutable heterogeneous labour than with perfectly substitutable homogeneous labour in production. This finding is based on results obtained from homogeneous and heterogeneous labour general equilibrium tax models calibrated to decile level income and consumption distribution data of UK households for the year 1994. We use labour supply elasticities implied by the substitution elasticity in households' utility functions and derive labour demand elasticities from the substitution elasticity in the production function.

Endogenous R&D networks when labour unions have preferences over wages and employment

We develop a model to analyse the pattern of R&D network formation when unions have relative preferences over wages and employment. Within a three-firm industry, we show that when the unions place a low weight on wages and technological spillovers are low, a partial R&D network that includes two firms but excludes the third emerges in equilibrium. In contrast, when the unions care a lot about wages, a complete R&D network that includes all firms emerges. For all other intermediate levels of union preferences over wages, there is no strong stable equilibrium network. Empirical implications emerge from these findings, which are also discussed.     

New forms of labour contract and labour flexibility in Russia

This paper assesses the claims that employment in the new Russian private sector relies heavily on informal and unregistered labour agreements and that the violation of existing labour law by new private employers is driven by their need for more flexible working arrangements.
The paper shows that these claims are unsupported on every count. The new private sector does not rely heavily on informal or illegal forms of employment and there is no evidence that it uses labour more flexibly, in any of the usual senses of the term, than the traditional sectors of the economy. The conclusion is that there is no economic justification for the systematic violation of the existing labour legislation. It is suggested, therefore, that enforcement of the existing law is a precondition for its effective reform in those areas in which it might be a barrier to restructuring.     

Technology transfers,foreign investment and productivity spillovers

This paper explores the relationship between foreign direct investment (FDI) and the productivity of host country domestic firms. We rely on a specially designed survey of over 4000 manufacturing firms in Vietnam, and separate out productivity gains along the supply chain (obtained through direct transfers of knowledge/technology between linked firms) from productivity effects through indirect FDI spillovers. In addition to identifying indirect vertical productivity spillovers from FDI, our results show that there are productivity gains associated with direct linkages between foreign-owned and domestic firms along the supply chain not captured by commonly used measures of spillovers. This includes evidence of productivity gains through forward linkages for domestic firms which receive inputs from foreign-owned firms.     

Poverty and monetary transfers in Belarus: Some options for gradual reforms

In this paper we shall be analyzing gradual poverty reducing reforms for monetary transfers in Belarus. Some evidence is offered in support of the claim that the effectiveness of the existing 'categorical' system of transfers might be improved by redirecting resources to specific groups of households. Using a decomposition of households into socio-economic groups, feasible marginal reforms are suggested, and their robustness is checked by both experimenting with different poverty lines and introducing a simplified form of labour supply responsiveness. Based on these findings, a microsimulation of a hypothetical transfer change among different groups of households is run. According to this microsimulation, all aggregate poverty indicators could be reduced.     

Fertility,household structure,and parental labor supply: Evidence from China

This study examines the effects of fertility on household structure and parental labor supply in China. To solve the endogeneity problem, we use a unique survey on households with twin children and a comparison group of non-twin households. The ordinary least squares estimates show a negative correlation between fertility and parental labor supply in rural China. Using twinning as a natural experiment, we do not find evidence on the negative effects of fertility on parental labor supply. By contrast, we find that the twinning-induced increase in fertility significantly enhances the coresidence of grandparents in rural China. We suggest that the negative effects of fertility on parental labor supply are mitigated by the childcare provided by grandparents in rural China. We also find that fertility does not induce coresidence of grandparents in urban China. Our results have important implications for population and public childcare policies.     

Rural labour market policies in Croatia,FYR of Macedonia and Turkey

Considerable differences are found among countries regarding the importance of the agricultural labour force, between rural and urban labour, and in poverty and living conditions in rural areas. Declines in the agricultural labour force and rural population are foreseen for each of the countries, but with significant variations between them. Showing different patterns over time, labour market developments in the sector and in rural areas have been shaped by the overall labour market institutions, conditions and factors in each country, such as the legal basis, educational attainment and migration flows, and the presence of non-agricultural activities in rural areas.     

A study on Spanish female labour supply with job offer restrictions

This paper analyses female working time taking into account restrictions on hours. Moreover, we compare two different specifications of employment opportunities. The first one assumes that the probabilities of receiving different job offers are constant whereas in the second one we incorporate the hypothesis that these probabilities depend on individual characteristics. The model is estimated using a sample of Spanish women from the Encuesta Piloto sobre Ganancias y Subempleo (1990). The results suggest that incorporating job restrictions is a valuable extension and that individual variables affect the availability of job offers.JEL Classification: J22This paper is based on the second chapter of my Ph.

Employment,labor supply and real wages in market disequilibrium

The purpose of this paper is to provide estimates of a disequilibrium labor market model which has been fitted to the US private non-farm sector and to the manufacturing sector. After examining the rationale of the ‘minimum’-type disequilibrium model, we reject it in favor of a formulation suggested by Chow. The latter provides not only a wage adjustment mechanism, but also a quantity adjustment mechanism and treats wages and quantities symmetrically. The empirical findings for both sectors support the disequilibrium formulation employed and reject the equilibrium hypothesis for the labor market.     

Intergenerational transfers and the social discount rate

This paper investigates the relationship between intergenerational asset transfers and the choice of the discount rate for use in cost-benefit analysis in a model of a competitive overlapping generations economy constrained by a socially managed exhaustible resource. Provided that there are no distortions in capital markets and that all agents hold perfect foresight, cost-benefit techniques will result in a Pareto efficient resource allocation if the discount rate is set equal to the market rate of interest. But since the path of the interest rate depends on the level of intergenerational transfers, cost-benefit techniques do not ensure a socially desirable distribution of welfare between generations; a social optimum will result only if intergenerational transfers are properly chosen and enforced. Decentralized private altruism may result in intergenerational transfers that both present and future individuals would agree are too small if members of the present generation attach positive weight to the general welfare of future generations, not simply their personal descendants. In a world where intergenerational transfers are non-optimal, second-best policy-making may imply a constrained optimum that is inefficient. Together, these findings suggest that cost-benefit analysis is at best a partial criterion to policy formulation that should be used only in conjunction with ethical principles that define the proper distribution of welfare between present and future generations.     

Political uncertainty and labour investment efficiency

ABSTRACT

We examine the impact of political uncertainty on the labour investment efficiency (LIE) of a firm. Using a sample of Chinese firms, we test the market discipline and managerial entrenchment hypotheses. Our findings suggest that political uncertainty adversely affects LIE. The results are consistent with the managerial entrenchment hypothesis. That is, firms hire more labour in a period of increased information asymmetry due to the political uncertainty, which deteriorates LIE. Our findings are robust to a battery of alternative measures of LIE and estimation methods. We conduct several additional analyses and document that the adverse impact of political uncertainty is stronger when the newly appointed government official is older, the firm is state-owned, the firm belongs to a politically sensitive industry or the firm operates in locations with stringent labour protection. By contrast, when the firm locates in a region with weak Chinese government intervention or after President Xi Jinping’s anti-corruption campaign, the adverse impact of political uncertainty on LIE is less pronounced. Last, we document that after hiring more labour, firms receive tangible and intangible benefits in terms of receiving more loans, collect more government subsidies, and able to re-establish some political connection but at the cost of lower performance.     

Job satisfaction,job match quality and labour supply decisions

This paper introduces job satisfaction into neoclassical theory of labour supply. This simple integration produces non-trivial results: job satisfaction is able to reduce disutility of labour, thus increasing labour supply; also, if job satisfaction is very high, labour could generate utility, while leisure could provide disutility. In this paper, job satisfaction, and thus job match quality, is specified in terms of appropriate collocation of the worker in the workplace; in short, the higher the matching between the investment in education and the task assigned in the workplace, the higher the job satisfaction. An empirical analysis substantiates the two main predictions of this paper, namely the key role of job satisfaction in time allocation and labour supply decisions and the plausibility of our view about job satisfaction.
