A demanda dinâmica por trabalho na indústria do Rio Grande do Sul : uma análise a partir de microdados

Jacinto, Paulo de Andrade January 2006 (has links)
O presente estudo tem como propósito fazer uma análise empírica da estrutura dos custos de ajustamento do emprego em indústrias no Brasil, a partir de dados microeconômicos de empresas industriais do Rio Grande do Sul. O estudo é motivado pelas grandes mudanças no emprego industrial nos anos 90 e 2000 e o fato estilizado de grande heterogeneidade na flutuação do emprego revelado na literatura de fluxos de emprego. Inicialmente, identifica-se a existência de diferentes estruturas teóricas para custos de ajustamento do emprego, que podem ser agrupadas em custos convexos e nãoconvexos e funções quadráticas (simétricas) e não lineares. Uma revisão da literatura empírica revela que poucos estudos no mundo e nenhum usando dados brasileiros consideram a possibilidade de custos não quadráticos e/ou convexos. A identificação da estrutura de custos de ajustamento divide-se em metodologias empíricas complementares. Primeiro, uma metodologia semi-paramétrica de flutuação do emprego industrial empregando modelos de sobrevivência e matrizes de transição, de modo inovador no Brasil, para diferenciar se os custos são convexos ou não. Segundo, dentro de um modelo paramétrico de demanda por emprego usual, permitindo comparações com a literatura, a estimação de forma funcional da função de demanda com custos de ajustamento quadrático e linear. Os resultados mostram que o modelo dinâmico com custos de ajustamento quadrático pode se útil para dar uma idéia da dinâmica do ajuste do emprego, porém não é o modelo mais adequado. Isso fica evidente a partir do momento em que os resultados do modelo geral, o qual contempla os custos de ajustamento quadrático e fixo, demonstram a necessidade de incorporar ambos os custos. Ao mesmo tempo, os modelos semi-paramétrico sugerem que os custos de ajustamento não-convexos têm mais apoio nos dados. / The aim of this study is, from microeconomic data from industrial companies of Rio Grande do Sul, to perform an empirical analysis of the employment adjustment costs in industries in Brazil. This study is motivated by the changes in industrial employment in the last and present decades and by the stylized fact of heterogeneity in job flows revealed in jog flow literature. Initially, is showed the existence of different theoretical structures to explain employment adjustment costs, which can be classified as convex and non-convex costs and quadratic (symmetrical) and non-linear functions. An empirical literature review reveals that few studies in the world, none of them using brazilian data, consider the possibility of non-quadratic and/or non-convex costs. The identification of the structure of adjustment costs is split in complementary empirical methodologies. First, an industrial job flow semi-parametrical methodology that uses survival models and transition matrixes, innovative in Brazil, to state if the costs are convex or not. Second, in the context of a usual employment demand parametric model, allowing comparisons with the literature, the estimation of the quadratic and linear adjustment costs’ demand function’s functional form. Results show that the dynamic model with quadratic adjustment can be useful to give a clue about the job adjustment dynamic, but that it’s not the most adequate one. This stays clear from the moment in which the results of the general model, which considers the lumpy and quadratic adjustment costs, show the need of incorporating both of these costs. At the same time, the semi-parametric models suggest that the non-convex adjustment costs have more data appeal.

The direction of trade and its implications for labour in South Africa

Cameron, Iona R January 2005 (has links)
This aim of this thesis is to analyse the demand for labour from trade with a selection of South Africa’s trading partners. It is expected that labour demand will be greater in trade with developed blocs. Trade between developing blocs, however, is thought to be more skilled labour intensive and such trade should have greater linkages. This ought to feed through into greater labour demand so that South-South trade may be more ‘labour creating’ than expected. As it is more skill intensive, it may also be more dynamic, which has implications for future growth and development. Factor content methodology is used to assess labour demand. Calculations consider linkages to other sectors (which will increase labour demand) and the use of scarce resources (which has an opportunity cost to labour). The findings support the claim that trade with developing blocs is more professional labour intensive. Evidence that it may be more dynamic and have greater linkages to labour is borne out in exports to SADC. Greater labour demand through linkages, however, is not evident in net trade to SADC. Neither are they of significance in trade with any of the other developing blocs so labour effects due to linkages appear to be negligible. The advantages of South-South trade may rather lie in the dynamic benefits that trade in higher technology goods provides. When scarce resources such as capital and professional labour are taken into account, it is found that labour demand is negative in net trade to all blocs. However, even without the problem of scarce resources, most blocs have a negative demand for labour in net trade. The indication is that with the present trade patterns, South Africa cannot expect trade to increase labour demand. Policy which could improve this situation would be to increase labour force skills, improve the flexibility of the labour market and develop sectors which are both more advanced as well as labour intensive. Despite the negative impact of trade on labour in general, it is found that trade does differ by direction and that for each labour type there are certain blocs where labour demand is positive. This is also the case in net trade for particular sectors. Such information could be used as part of a targeted trade policy to assist in the marketing of particular sectors in trade and also for increasing labour demand for certain labour groups.

Determinantes de la demanda de trabajo en la economía peruana, 2010-2019

Chavesta Ayasta, Angelli Gianella January 2023 (has links)
El objetivo de la presente investigación es analizar los determinantes de la demanda laboral en los sectores económicos que logran insertarse dentro del mercado de trabajo peruano. Se empleó un enfoque cuantitativo y el modelo econométrico de datos de panel, estudiando la influencia que pueden generar las variables, bajo parámetros que logren explicar el crecimiento en el mercado laboral en 15 sectores económicos, utilizando datos extraídos de la Encuesta Economía Anual durante el periodo 2010-2019. Como variable dependiente se utilizó la demanda laboral medida a través del promedio de personal ocupado por cada actividad económica y como variables explicativas la remuneración, productividad, ventas y densidad de capital. Entre los principales resultados se pudo determinar que durante el periodo de análisis, las variables remuneración y ventas son estadísticamente negativas, logrando explicar la teoría de la demanda de trabajo, donde se refleja la dinámica negativa que enfrenta los cambios negativos de salario hacia el trabajo; en tanto existe una relación directa con la variable productividad estadísticamente positiva, reconociendo que un mayor proceso productivo se determina bajo los recursos de empleabilidad aplicados y por último, la densidad de capital, como un determinante adicional, aplicado y evidenciando que la inversión de las empresa para demandar mayor trabajo, causa una influencia tanto positiva como negativa para el modelo. / The objective of this research is to analyze the determinants of labor demand in the economic sectors that manage to insert themselves into the Peruvian labor market. A quantitative approach and the panel data econometric model were used, studying the influence that the variables can generate, under parameters that explain the growth in the labor market in 15 economic sectors, using data extracted from the Annual Economy Survey during the period. 2010-2019. Labor demand was used as the dependent variable, measured through the average number of personnel employed by each economic activity, and remuneration, productivity, sales and capital density were used as explanatory variables. Among the main results, it was determined that during the analysis period, the variables remuneration and sales are statistically negative, explaining the theory of labor demand, which reflects the negative dynamics that face negative changes in salary towards work; while there is a direct relationship with the statistically positive productivity variable, recognizing that a greater productive process is determined under the employed employability resources applied and finally, the capital density, as an additional determinant, applied and evidencing that the company's investment to require more work, causes both positive and negative influence for the model.

An analysis of African reluctance to meet the labour demands of the Transvaal colony as expressed in the Labour Commission of 1903 and the South African Native Affairs Commission, 1903-1905

Masina, Edward Muntu 25 August 2009 (has links)
The Transvaal Colony experienced a huge problem with the scarcity of African labour for the mines and for the farms after the South African War. From 1901 to 1906 African labourers displayed great reluctance to meet the labour demands of the Transvaal colony. Both black and white witnesses to the Transvaal Labour Commission (TLC) and the South African Native Affairs Commission (SANAC) gave their views regarding the reasons why African labourers were unavailable for wage labour. The Chamber of Mines dominated the proceedings of the TLC so that in the end very little objective information could be gained from the TLC. Africans themselves, testifying before SANAC stated a number of grievances which might have been responsible for the widespread withdrawal from employment on the mines. It became clear that Africans preferred to work independently rather than to provide labour for whites who ill-treated them. This they could only do if land was available to them. / History / M.A. (History)
