On Labor Complementarity, Cultural Frictions and Strategic Immigration Policies

In this paper we consider a model with two industrialized countries that face a flow of immigration from the "rest of the world." The countries differ in three characteristics: the labor complementarity between the "native" population and immigrants, the population size, and the magnitude of the cultural friction between the natives and immigrants. We consider a non-cooperative game between two countries' when their strategic instrument is the choice of an immigration quota and the world immigrant wages introduce the spill-over effect between two countries. We first show that the quota game admits unique pure strategies Nash equilibrium. We then compare the equilibrium choices of two countries and show that even though the larger country attracts more immigrants, it chooses lower quota than its smaller counterpart. It also turns out that higher degree of labor complementarity between natives and immigrants and a lower degree of cultural friction between two groups yield higher immigration quota. We also examine the welfare implications of countries choices' and argue that coordinated and harmonized immigration policies may improve the welfare of both countries.

Career Crisis? Impacts of Financial Shock on the Entry-Level Labor Market: Evidence from Thailand

We utilize Thailand's the financial crisis in 1997 as a natural experiment which exogenously shifts labor demand. Convincing evidence from the Thailand Labor Force Survey support the hypothesis that both employment opportunities and wages shrunk for new entrants after the crisis. We find that workers who entered before the crisis experienced job losses and wage losses. But these losses were smaller than those of new entrants after the crisis. We also find that new entrants after the crisis experienced a 10% reduction in the overtime wages compared to new entrants before the crisis.

The Changing Nature of Employment and the Reform of Labor and Social Security Legislation in Post-Apartheid South Africa

This paper tries to understand the current status of South African labor market, which is changing in contradictory directions, i.e. a strengthening of the rights and protection of workers at the same time as the flexibilization of employment, in the context of the characteristics of labor and social security legislation in South Africa, as well as the nature of labor and social security reforms after democratization. We put emphasis on the corporatist nature of labor policy-making as the factor influencing the course of reforms; it is argued that the apparently contradictive changes can be explained consistently by the corporatist labor policy-making process which has been practiced notwithstanding the problem of representativeness.

Backward-bending of labor supply function and free riders

It seems like that backward- bending of labor supply function can be observed in Central Asian Countries such as Uzbekistan and Kazakhstan. People’s basic needs of life are satisfied and they do not increase labor supplies even if wage increases. It is possible to find some cases in which slowdowns increase, when a manager in a firm enforces penalties for workers have slowdowns. This phenomenon occurs because a worker prefers the position of equilibrium on the labor supply function always in the upper direction. This article explains the increase of free-riders by penalties and how to avoid them.

International labor migration in Vietnam and the impact of receiving countries' policies

Labor export has been part of Vietnam’s socio-economic development strategy since the beginning of the doi moi era. Recent years, Vietnam has sent about 80,000 workers abroad per year. Vietnam has become a major source country of unskilled foreign workers for high-income East Asian countries. However, in these receiving countries, the desertion rate among Vietnamese workers is quite high, compared with that for workers from other countries. This paper examines the impact of Korean and Japanese policies for receiving foreign workers applied to and implemented in Vietnam, as well as the impact of Vietnamese labor sending system, on the problem of runaway workers.

Tariff reductions and labor demand elasticities : evidence from Chinese firm-level data

International production fragmentation has been a global trend for decades, becoming especially important in Asia where the manufacturing process is fragmented into stages and dispersed around the region. This paper examines the effects of input and output tariff reductions on labor demand elasticities at the firm level. For this purpose, we consider a simple heterogenous firm model in which firms are allowed to export their products and to use imported intermediate inputs. The model predicts that only productive firms can use imported intermediate inputs (outsourcing) and tend to have larger constant-output labor demand elasticities. Input tariff reductions would lower the factor shares of labor for these productive firms and raise conditional labor demand elasticities further. We test these empirical predictions, constructing Chinese firm-level panel data over the 2000--2006 period. Controlling for potential tariff endogeneity by instruments, our empirical studies generally support these predictions.

Migration, labor and business in the worlding cities of the Arabian Peninsula

This short essay, built on a foundation of more than a decade of fieldwork in the hydrocarbon-rich societies of the Arabian peninsula, distills a set of overarching threads woven through much of that time and work. Those threads include a discussion of the social heterogeneity of the Gulf State citizenries, the central role of development and urban development in these emergent economies, the multifaceted impact of migrants and migration upon these host societies, and the role of foreign 'imagineers' in the portrayal of Gulf societies, Gulf values, and Gulf social norms.

Authoritarianism and labor market : preference of labor policies in the Arab Gulf countries

Migrant and labor issues are a primary concern in the Arab Gulf countries. With focus on the economic and political conditions that influence actors' decisions when framing labor policies, this study analyzes how preferences of such policies are formed and explains why the governments of the Arab Gulf countries attempt to implement less economical policies. The findings suggest that governments avoid concessions for enterprises required to implement more economical policies and chose uneconomical ones to maintain authoritarian regimes.

Land and labor reallocation in pre-modern Japan : a case of a northeastern village in 1720-1870

In agricultural societies, adjusting land and labor according to changes of labor endowment that result from family life cycle events is premised on making full use of resources for each farming household and for the economy as a whole. This paper examines how and how well households in pre-modern Japan reallocated land and labor, using a population register covering 150 years from 1720–1870 for a village in the Tohoku region. We find that households reacted to equalize their production factors; land-scarce households tended to acquire or rent-in land and out-migrate their kin members, while land-abundant households tended to release or rent-out land, in-migrate kin members, or employ non-kin members. Estimates suggest that more than 80% of the surplus or deficit area of land was resolved if the household rented or "sold" land. We discuss a potential underlying mechanism; namely, that the village's collective responsibility for tax payment (murauke) motivated both individual households and the village as a whole to reallocate land and labor for the efficient use of resources.

What best transfers knowledge? : capital, goods, and innovative labor in East Asia

This paper compares three knowledge carriers—trade, foreign direct investment (FDI), and inventors—as knowledge mediums, and investigates their effects on knowledge flow in East Asia from 1996 to 2010. Using patent citations as a proxy for knowledge flow, this paper shows that FDI and inventor mobility have positive effects on increasing patent citations in East Asia when the technological portfolios of two countries are less similar. While trade shows statistical significance, the effect is inconsistent according to the regression models.

Fundamentación del conjunto tractor-apero para la labor de surcado y su influencia en el consumo energético en cultivos de raíces y tubérculos

El cumplimiento de los objetivos agrotécnicos de los cultivos de raíces y tubérculos exige que la labor de surcado configure un caballón que permita el trabajo de los posteriores aperos que participan en las demás labores de cultivo. En la agricultura cubana se emplean diversos tipos de surcadores que difieren en las características de los elementos aporcadores. Este hecho afecta a la capacidad de trabajo del conjunto tractor-apero y por extensión en el consumo de combustible y el rendimiento del cultivo. El objetivo de este trabajo ha sido fundamentar el empleo del apero más adecuado para la labor de surcado en cultivos de raíces y tubérculos (patata, boniato, yuca) en Fluvisoles, teniendo en cuenta el comportamiento de las dimensiones y forma del caballón, cualidades tecnológicas explotativas del conjunto tractor-apero, consumo energético del proceso productivo y el rendimiento agrícola. Los tratamientos considerados estuvieron determinados por la utilización del surcador fertilizador IIMA-BALDAN 4.500 (T1), y los surcadores aporcadores SA-5 (T2) y SA-3 (T3). En los tres tratamientos se alcanzó un perfil de la sección transversal del caballón de configuración cóncavo-convexo. El surcador BALDAN logró el mejor comportamiento de los indicadores tecnológico-explotativos lo que se tradujo en la mayor capacidad de trabajo de 1,36 ha h-1 y el menor consumo de combustible de 5,38 L ha-1. Este mismo tratamiento proporcionó el mayor rendimiento medio de los cultivos superando en un 43,2% al del surcador SA-5 y en un 57,9% al del surcador SA-3. Desde el punto de vista energético T1, obtuvo una mejor eficiencia energética superior en un 43,5% a la del tratamiento T2, y en un 57,1% a la del tratamiento T3. ABSTRACT The achievement of agrotechnical objectives in the cultivation of roots and tubers demands the plow through activity creates a ridge to allow the work of subsequent farming tools participating in other cultivation works. In Cuban Agriculture various kinds of furrowers are used which differ in the characteristics of their earth up elements. This fact affects work capacity of the tractor-farming tool combination and by extension to fuel consumption and cultivation yield. The aim of this work has been to support the use of the most accurate farming tool in the plow through activity for the cultivation of roots and tubers (potato, sweet potato, cassava) in Fluvisoils, taking into account the behaviour of the ridge´s dimensions and shape, technologic-explotative qualities of the tractor-farming tool combination, energy consumption of the productive process and agricultural yield. The treatments considered were determined by the use of fertlizing furrower IIMA-BALDAN 4.500 (T1), and the earth up furrowers SA-5 (T2) and SA-3 (T3). During the three treatments a transverse section profile of the ridge under concave-convex configuration was obtained. The furrower BALDAN achieved the best behaviour of the technologic-explotative indicators, which was translated into the largest work capacity of 1,36 ha h-1 and the smallest fuel consumption of 5,38 L ha-1. This treatment also provided the biggest average yield of the cultivation, overcoming in a 43,2% the furrower SA-5 and furrower SA-3 in a 57,9%. From the energetic point of view T1 gained better energetic efficiency than treatment T2 in a 43,5% and treatment T3 in a 57,1%.

La nueva norma UNE 153010. Una labor de consenso

La norma UNE 153010:2003 recogía requisitos para el subtitulado para personas sordas a través de teletexto. Fue el resultado de varios años de trabajo en el Subcomité 5 del Comité Técnico de Normalización (CTN) 153 de AENOR. Los cambios en los últimos años en cuanto a los medios audiovisuales llevaron a dicho Subcomité a plantearse en el año 2008 la posibilidad de actualizar los contenidos de esta norma, con el fin de adaptarse a nuevas tecnologías, como los DVD, la televisión digital o la televisión emitida a través de Internet. Inicialmente se planteó la posibilidad de realizar normas específicas de subtitulado para cada tecnología de emisión, pero finalmente se decidió desarrollar una norma general de subtitulado que fuera de aplicación general. Tras un largo periodo de trabajo, la nueva versión de la norma UNE 153010 está a punto de ver la luz, dado que se encuentra en periodo de información pública. En este artículo se narra el proceso de desarrollo de esta norma y se describe los aspectos más importantes de la misma, resultado de una intensa labor con gran voluntad de consenso por parte de las entidades implicadas.
