“商业劳动创造价值”的现代分析

商业劳动包括附带的生产性劳动、纯商业劳动以及管理性、开发性商业劳动,其中开发性商业劳动是最高级的商业劳动。商业劳动能否创造价值需要具体问题具体分析,对经营的单个商品来说,对商业企业的价值总量来说,有创造价值和不创造价值之分;从社会再生产全过程来讲,所有的商业劳动都是创造价值的。因此,"商业劳动创造价值"的命题且具有重大、深远的实践意义。     

Labour NGOs: An Alternative Form of Labour Organizing in Indonesia, 1991–1998

Although Indonesia's labour non-government organizations (NGOs) are in many ways unique, they are in fact part of a global surge in non-traditional labour activism, in which international and indigenous labour NGOs have played an important role. This contribution examines the contribution of labour NGOs to the reconstruction of the Indonesian labour movement in the 1990s and its implications for our understanding of the contemporary labour movement more generally. It argues that the Indonesian experience suggests theorists and unionists should broaden their understanding of the labour movement to make room for non-traditional forms of labour movement organizations, such as labour NGOs, that have the potential to (and do) contribute to that movement.     

基于劳动的分工与贸易的逻辑生成——亚当·斯密分工与贸易理论的文本解读

亚当·斯密在《国富论》中揭示了从劳动到分工、从分工到贸易的经济学逻辑。分工的产生有其社会必然性,它能够极大地促进技术进步,提高劳动效率,从而增加社会财富。分工是商品经济的路径依赖,分工的发展导致贸易的普遍化和商业社会的生成。     

Angebotsökonomie: wenig Innovation — viele Jobs!

Deregulation of labour markets through structural reforms as proposed by supply side economists has a negative impact on innovation and brings down the growth rates of labour productivity. This paper discusses why the Schumpeter II innovation model is functioning poorly with higher labour turnover. Deregulation of labour markets also changes power relations between capital and labour, which leads to lower wage growth. Panel data analyses show that a one per cent lower wage increase leads to 0.32-0.49% lower growth of value added per labour hour.

The role of trade and offshoring in the determination of relative wages and child labour

Incorporating family decisions in a two-period model of the world economy, we predict that trade liberalization raises the skill premium and reduces child labour in developing countries where the adult labour force is sufficiently well educated to attract production activities from abroad that will increase the demand for skilled relative to unskilled labour. Elsewhere, liberalization will reduce the skill premium, but it will not necessarily raise child labour. Our prediction is not rejected by the data, and it explains why child labour is negatively associated with trade openness in those developing countries where the labour force was relatively well educated when the liberalization took place, but not elsewhere.     

Can labour market institutions mitigate the China syndrome? Evidence from regional labour markets in Europe

This paper investigates how labour market regulations alter the adverse impact of rising import competition from China in European local labour markets between 1997 and 2006. The paper constructs measures of regional exposure to Chinese imports based on previous literature and on regional labour market frictions exploiting involuntary labour reallocations. Taking into account the endogeneity of import competition and its interaction with labour market regulations, the paper finds that regions more exposed to the rise of China have suffered from a reduction in manufacturing employment shares. This shock grows larger with regional labour market frictions; hence, it exacerbates the impact of trade shock on employment. Moreover, the paper finds that employment in public services, and not in construction or private services sector, absorbed the negative shock to the manufacturing sector. The unemployment rate, the labour force participation rate and wages in all sectors are unresponsive to import competition from China.     

Opening of China's Trade,Labour Market Reform and Impact on Rural Wages

Government policy in China supports urban wages at the expense of returns to farm labour. A model is developed to estimate how WTO accession and complementary labour market reform will influence factor returns in China. With WTO membership, a larger cut in manufacturing tariffs compared to agriculture will improve agriculture's terms of trade and will raise the agricultural wage. Complementary labour market reforms will further boost farm wages as labour exits agriculture in large numbers. We estimate that WTO membership and complementary labour market reforms will result in a decline in the agricultural labour force by about 25 per cent.     

Economic integration across Latin America: Evidence from labour markets, 1990–2013

Combining macroeconomic and microeconomic data and three indicators of international market integration, this paper assesses the degree to which Latin American labour markets are integrated. The results suggest that relative to East Asia, Latin American labour markets are somewhat more integrated, but considerable differences across countries persist. In addition, the evidence indicates that the degree of labour market integration across Latin American borders is significantly less than that of labour markets within the United States in two of the three indicators. These differences may suggest opportunities for efficiency gains from further labour market integration.     

Services Offshoring and its Impact on Productivity and Employment: Evidence from Germany, 1995–2006

Economists have recently recognised services offshoring as an important influence on domestic labour market outcomes. Services are of particular interest since their significance has grown in terms of both quantity and quality. Only one and a half decades ago, most services were considered non‐tradable, but the emergence and development of new information and communication technologies has made many services internationally tradable. The liberalisation of international trade in services trade has further accelerated the volume of services trade. Our econometric estimations focus on services offshoring by German manufacturing sectors. We use revised input–output data from 1995 to 2006. We first estimate the impact of services offshoring on labour productivity. We then measure the effects of services offshoring on labour demand. The results show that services offshoring increased sectoral labour productivity, but reduced German manufacturing employment. The overall results suggest that labour demand decreased over 1995–2006, because labour‐reducing productivity and substitution effects dominated labour‐augmenting scale effects from services offshoring.
