Labour Adjustment and Efficiency in Hungary

Transition from socialist to market economy brought drastic changes to the Hungarian labour market. Employment fell by 1.6 million, i.e., by more than 25% during the early transition period, while unemployment jumped from practically nil to over 14% within four years. The rapid economic growth of the recent years could only create relatively few jobs, even though the unemployment rate continuously declined, and is less than 6% since 2001. This paper describes labour adjustment after the transitional recession, and its relationship to corporate efficiency during the recovery period, based on a panel of medium-sized and large Hungarian firms. Labour demand is also related to firm level productive efficiency.labour demand, productive efficiency, firm in transition economy

Lumpy capital adjustment and technical efficiency

This paper investigates the impact of lumpy capital adjustment on productivity at the firm level using data on Japanese manufacturing industries. We estimate stochastic production frontiers, taking firm heterogeneity into account. We find that investment spikes are negatively related to technical efficiency. Furtermore, we find a negative relationship between machinery capital age and measured efficiency.

Efficiency wage theory, labormarkets, and adjustment

Conventional labor theory argues that wages are determined by the interaction of labor supply and demand. Policy analysis on wage rigidity has emphasized distortions arising from exogenous intervention. One emphasis in adjustment lending has been deregulation of labor markets. Efficiency wage models of unemployment try to explain persistent real wage rigidities when unemployment persists. Their central assumption is that higher real wages can improve labor productivity. A major implication of these theories is that wages (and hence labor markets) may be unresponsive to typical macroeconomic policies that seek to lower real wages, change resource allocation, and reduce open unemployment. The three central macroeconomic implications of efficiency wage theory are : 1) there is an equilibrium"natural"level of open unemployment, which differs among groups in the labor force and cannot be affected by demand management policies; 2) when reducing the level of production, the typical firm will resort to laying off labor instead of reducing wages, thereby introducing a significant wage inertia and an overshooting of open unemployment; and 3) wages do not respond to clear the labor market and are not responsive to macroeconomic policies and microeconomic deregulation. The authors conclude that applying the theory in developing countries requires suitably defining labor costs and tackling the problem of segmentation of the labor market.Environmental Economics&Policies,Economic Theory&Research,Banks&Banking Reform,Municipal Financial Management,Youth and Governance

Adjustment of Inputs and Measurement of Technical Efficiency: A Dynamic Panel Data Analysis of the Egyptian Manufacturing Sectors

The purpose of this paper is to construct a dynamic stochastic production frontier incorporating the sluggish adjustment of inputs, to measure the speed of adjustment of output, and to compare the technical efficiency estimates from this dynamic model to those from a static model. By assuming instantaneous adjustment of all inputs, a static model may underestimate technical efficiency of a production unit in the short-run. However, in this paper I show that under the assumption of similar adjustment speed for all inputs, a linear partial adjustment scheme for output characterizes the dynamic production frontier. The dynamic frontier with time-invariant technical efficiency is estimated using the system GMM (generalized method of moments) estimator. Applying the model and estimation method on a panel dataset spanning nine years of data on private manufacturing establishments in Egypt, I find that 1) the speed of adjustment of output is significantly lower than unity, 2) the static model underestimates technical efficiency by 4.5 percentage points on average, and 3) the ranking of production units based on their technical efficiency measures changes when the lagged adjustment process of inputs is taken into account.

Trade Liberalisation with Costly Adjustment

The paper analyses the efficiency and the distributional effects of eliminating a tariff in a protected sector, in a Heckscher-Ohlin model of trade with costs of adjustment. The tariff can be eliminated at the onset or after a while. In case of postponing it the government may pre-announce the policy change or may not do it and surprise the private sector. It is shown that while large adjustment costs reduce the efficiency gains from trade liberalisation, small to moderate adjustment costs may raise the efficiency gains from a pre-announced liberalisation. The adjustment costs reduce the effects on factor returns from a sudden unanticipated liberalisation. The distributional effects of trade liberalisations are more complex when the policy is pre-announced. For small and moderate levels, the adjustment costs may increase the effects of the policy on factor returns. Also, the “value of the announcement” rises with the adjustment costs.adjustment costs; trade liberalisation

Investment Utilisation, Adjustment Costs, and Technical Efficiency in Danish Pig Farms

In this paper, we present a theoretical model for adjustment costs and investment utilisation that illustrates their causes and types and shows in which phases of an investment they occur. Furthermore, we develop an empirical framework for analysing the size and the timing of adjustment costs and investment utilisation. We apply this methodology to a large panel data set of Danish pig producers with 9,281 observations between 1996 and 2008. The paper further contributes with a thorough discussion of the calculation and deflation of capital input from microeconomic data. We estimate an output distance function as a stochastic frontier model and explain the estimated technical inefficiencies with lagged investments, farm size and age of the farmer. We allow for interaction effects between these variables and derive the formula for calculating the marginal effects on technical efficiency. The results show that investments have a negative effect on farm efficiency in the year of the investment and the year after accruing from adjustment costs. There is a large positive effect on efficiency two and three years after the investment. The farmer’s age and the farm size significantly influence technical efficiency, as well as the effect of investments on adjustment costs and investment utilisation. These results are robust to different ways of measuring capital.investment utilisation, adjustment costs, stochastic frontier analysis, technical efficiency, pig production, Denmark

Poverty and income distribution during adjustment : issues and evidence from the OECD project

Drawing lessons from country studies, the authors examine the effects of adjustment policies on the distribution of income in Chile, Cote d'Ivoire, Ecuador, Indonesia, Malaysia, and Morocco. After analyzing the issues that must be confronted in designing adjustment programs with a focus on poverty, they synthesize the main conclusions of the different country studies. With simulation exercises they explore the effects of the design of the adjustment packages on poverty and on the sustainability of the measures undertaken in these countries. These exercises show considerable diversity in the evolution of income distribution during adjustment. They also expose the fatal flaws of narrowly designed adjustment programs. Adjustment programs - whether focused on efficiency or on welfare - will fail when they do not recognize the interdependence of the three criteria of efficiency, welfare, and political feasibility. Adjustment programs must be carefully packaged to fit country circumstances, taking into account both the political and economic environments.Economic Stabilization,Inequality,Environmental Economics&Policies,Economic Theory&Research,Health Economics&Finance

Trade liberalisation with costly adjustment

This paper discusses the welfare effects of trade in a Heckscher-Ohlin model of trade with costs of adjustment. The paper analyses the efficiency and the distributional effects of eliminating a tariff in a formerly protected sector. The tariff can be eliminated at the onset or after a while. In case of postponing the elimination of the tariff, the government may pre-announce the policy change or may not do it and surprise the private sector. It is shown that while large adjustment costs reduce the efficiency gains from trade liberalisation, small to moderate adjustment costs may raise the efficiency gains from a pre-announced liberalisation. The (net) adjustment costs reduce the welfare gains and losses of owners of production factors from a sudden unanticipated liberalisation. The policy risk is partially shifted towards owners of firms. The distributional effects of trade liberalisations are more complex when the policy is pre-announced. The adjustment costs may increase the gains and losses of owners of the production factors, for small and moderate levels. Also, the announcement that the tariff will be eliminated affects the value of the firms, and when the adjustment cost are not high it may raise rather than reduce the value of the firms in the formerly protected sector.

Overview of Adjustment Policies in Industrialized Countries

Arguments for adjustment policies center on efficiency, equity and political economy considerations. The principal types of policies, targeted to individuals, firms or communities, are reviewed. A number of general issues relating to adjustment policies are identified.Political Economy,

A Flexible Adjustment Model of Employment with Application to Zimbabwe's Manufacturing Industries

This paper presents a dynamic adjustment model of employment. The model is applied to a panel of ten Zimbabwean manufacturing industries observed over the period 1970-1993. The adjustment process is industry and time specific. The adjustment parameter is specified in terms of factors affecting the speed of adjustment. Industries are assumed to adjust their labour inputs towards a desired level of labour-use. A labour requirement function is specified in terms of observable variables and is used to model the desired level of labour-use. In evaluating alternative specifications, we used a flexible translog functional form where the labour requirement is a function of wages, output and capital stock. The empirical results show that in the long run, employment demand responds greatest to wages, followed by capital stock changes, and least by output. The sample mean annual speed of adjustment in employment is 33%. We further examined labour-use efficiency of different industries defined as the ratio of optimal to the observed level of employment. The rate of over-use of labour ranges across industries from 6.8% to 8.1% over the period of this study.Dynamics; employment; labour-use efficiency; panel data; Zimbabwe's manufacturing; speed of adjustment;
