Efficiency wages,unemployment and international factor movements

"This paper examines the implications of unemployment resulting from efficiency wages for international factor movements in a standard Heckscher-Ohlin model where the relative size of the endowments of skilled and unskilled workers and the efficiency wage induced unemployment level in the unskilled labour market are simultaneously determined given the population, supply of capital and its distribution in the economy.... It is shown that the optimum labour inflow in the market with domestic distortion and the optimum capital inflow are always positive because they reduce the severity of distortion by raising employment and income for the residents. The income and employment of foreigners also increase. Under this situation the optimum labour or capital outflow on the other hand is always zero. These conclusions directly contradict the result obtained for international factor movements in the presence of exogenously determined unemployment."     

The rise of the machines: Capital imports and real manufacturing wages in 57 nations

Outward-oriented policy reform has attracted a large number of academics to the study of the trade-labour market nexus. One of these fields has focused on capital intensive (machinery) imports and its effect on manufacturing wages. The skill-enhancing-trade (SET) hypothesis was put forth to explain a potential relationship where an inflow of capital imports results in increased demand for skilled labour and decreased that of unskilled labour, and thus resulted in a rise in skilled wages and a decrease in their unskilled counterparts. This study revisits this hypothesis with a panel from the manufacturing sector of 57 nations. We improve upon previous studies in a number of ways. We add developed nations to the sample and examine capital imports from rich countries as well as the rest of the world. This takes into account the prominence of vertical production networks in international trade. We adhere closely to the neo-classical trade model and employ definitions of skilled and unskilled workers that capture the production process of particular items. Finally, we fit a robust dynamic panel data model that accounts for the endogeneity of the determinants of trade and wages. In this way we test whether the SET hypothesis is generally applicable as opposed to previous studies which use an ad hoc selection of countries and variables. We find that the SET hypothesis is not driving changes in manufacturing wages. Instead, worker productivity and GDP per capita explain these labour market outcomes.     

Structural Change,Economic Crisis and International Labour Migration in East Asia

Increased international labour migration was one important dimension of structural change and globalisation in East Asia from the mid 1980s. Large international movements of mainly unskilled contract labour occurred in response to widening wage gaps between more and less developed countries in the region as the former experienced rapid structural change. Labour importing countries increasingly relied on unskilled migrant workers in less preferred jobs, in both export‐oriented and non‐tradable goods industries. The Asian economic crisis dramatically influenced the context in which international labour mobility had occurred in the pre‐crisis period. Important issues included a possible reversal in role of international migration in structural change, both among unskilled contract workers and more skilled migrants, and replacement of migrants by unemployed local workers. The paper argues that the Asian economic crisis did not reverse the fundamental trend toward greater reliance on unskilled migrant workers in agriculture, manufacturing and service industries. Business and professional migration remained significant and even rose in some countries during the crisis. However, several countries were forced to develop a more coherent policy towards migrant workers, in light of the social impact of the crisis.     

Trade liberalisation and human capital adjustment

This paper highlights the way in which workers of different ages and abilities are affected by anticipated and unanticipated trade liberalisations. A two-factor (skilled and unskilled labour), two-sector Heckscher-Ohlin trade model is supplemented with an education sector which uses skilled labour and time to convert unskilled workers into skilled workers. A skilled worker's income depends on her ability, but all unskilled workers have the same income. Trade liberalisation in a relatively skilled labour abundant country increases the relative skilled wage and induces skill upgrading by the existing workforce, with younger and more able unskilled workers most likely to upgrade. But not all upgraders are better off as a result of the liberalisation. The older and less able upgraders are likely to lose. For an anticipated liberalisation we show that the preferred upgrading strategies depend on a worker's ability and that much of the upgrading will take place before the liberalisation. Hence some workers who would have upgraded had they anticipated the liberalisation will not if it is unanticipated, and adjustment assistance that applies only to post-liberalisation upgraders will fail to compensate some losers and distort the upgrading decisions of others.     

Economic Reform,Skill Formation and Foreign Capital

Does trade liberalisation promote skill formation and positively influence the inflow of foreign capital in an economy? How do incentives offered to foreign capital affect skill formation and skilled‐unskilled wage inequality? Is liberalisation of agricultural exports counterproductive to skill formation and foreign capital inflow in the economy? We try to capture these relationships between foreign capital and skill formation in a small open economy facing various exogenous shocks. Among other results, we show that import liberalisation increases skill formation and the inflow of foreign capital in the country. We explore the evolving state of the skilled‐unskilled wage gap in a regime of greater skill formation.     

对外贸易对我国城乡收入差距影响的实证分析

本文利用1978-2007年间我国31个省市的面板数据,对进出口贸易对我国城乡收入差距影响的效应进行了实证研究。研究结果表明,对外贸易是影响我国城乡收入差距的重要因素。对外贸易主要通过就业和工资水平途径影响国内城乡收入差距,不同时期,对外贸易对我国不同类型劳动者的就业及其工资水平的影响不同。对外贸易对我国就业的影响主要表现为就业数量扩大效应和就业质量偏向效应,就业数量扩大效应有利于缩小城乡收入差距,就业质量偏向效应扩大了城乡收入差距,对外贸易对我国城乡居民收入差距的影响就是这两种效应的综合。因此,我国政府应高度重视对外贸易的城乡收入分配效应,趋利避害,综合实施各种措施,同时达到经济发展和城乡居民收入差距缩小的目标。     

International migration versus foreign investment in the presence of unemployment

"This paper extends the standard (two-factor, one-good) model of international factor movements, to include unemployment due to a minimum-income guarantee within the capital-abundant country. From this country's perspective, we establish important departures from previous (full-employment) results. Most notably, our analysis shows that: (1) free factor mobility is worse than no mobility; (2) the optimal degree of labour migration is zero; and (3) national welfare can always be maximized by an optimal flow of capital. The analysis is then extended to examine: (1) illegal migration; (2) subsidization of employment; and (3) alternative views of unemployment."     

Foreign direct investment and civil violence in Sub-Saharan Africa

Despite the steady growth in foreign direct investment (FDI) flow into Sub-Saharan Africa (SSA), which is facilitated by the United Nations "2030 Agenda for Sustainable Development", economic development in SSA countries remains relatively weak, due in part to frequent incidents of civil violence. The critics of FDI inflow into SSA posit that the cross-border capital flow fuels civil conflict and unrest, whilst the proponents maintain that FDI inflow helps developing countries raise their economies. To reconcile these two views, this paper considers the impact of FDI on civil violence in SSA by distinguishing recipient industries of FDI. The results from a new general equilibrium theory suggest that an increase in resource-directed FDI inflow to countries where the resource sector is skilled labour (unskilled labour) intensive reduces (increases, respectively) the risk of violence. Using a panel data consisting of 34 SSA countries for 1972–2013, the dynamic panel estimates provide support for our theoretical findings. In particular, an increase in FDI inflow reduces the risk of civil violence for skilled labour intensive fuel-resource-rich SSA countries. However, the likelihood of violence can increase in FDI inflow for countries that are rich in unskilled labour intensive non-fuel, ore and other mineral resources.     

Globalisation, internal labour markets and the migration of the highly skilled

Over the last decade highly skilled migration has been gaining relative importance in European migration flows. Following the goods and factor markets the market for highly skilled labour has thus also started to globalise. How are the globalisation processes of the world-wide goods, capital and labour markets interlinked? What role do international enterprises and their internal labour markets play in increasing highly skilled migration? What trends can be expected for the future?     

Rural–urban migration,urban unemployment and the structural transformation of a dual economy

This paper restructures the Harris–Todaro model in such a way that rural–urban migration in the presence of urban unemployment brings in the structural transformation desired for a developing dual economy by expanding the industrial sector before any policy is introduced to cure the domestic factor market distortion. Furthermore, migration may also help to eliminate unemployment as well as the wage gap in the economy. When international trade is introduced in this restructured dual economy, trade policies would have new implications; for example, unlike in the original Harris– Todaro structure, the import tariff may bring full employment and eliminate wage gaps between the sectors.     

Unemployment,environmental policy,and international migration

In this paper, we investigate the effects of an increase in emission tax, a decrease in fixed manufacturing wage rate, and an increased inflow of foreign workers on competitive wages, the environmental stock, the economic welfare of the representative consumer, and employment in the presence of a pollution abatement equipment sector and unemployment. Our main findings are that an increase in emission tax and a decrease in the urban minimum wage rate decrease unemployment, and international immigration may increase the competitive wage rate, employment rate, stock of environmental capital, and economic welfare of the representative worker.     

Foreign direct investment and wages: a cross-country analysis

While globalization has led to overall economic growth in a number of countries, questions abound on its distributional effects, especially on rising wage inequality across nations. The main objective of this study is to investigate empirically the effects of foreign direct investment (FDI) on wages in a cross-country setting. We investigate the general equilibrium propositions that capital inflows (outflows) increase (lower) wages in host (home) countries due to the change in relative factor endowments. We also explore whether capital inflows have differential impacts on skilled and unskilled wages in developing economies. Time-series data on 26 countries, 15 developed and 11 developing, are used to fit the labour share equation derived from a translog GNP function with net FDI stock as one of its arguments. Results confirm that capital movement brings about a cross-country convergence of wages. However, there is some evidence that inward FDI flows increase the wage gap between skilled and unskilled workers in developing countries.     

Optimal immigration, education and growth in the long run

The paper extends Manning's model on education and balanced growth to include labour immigration. Each immigration unit is assumed to consist of one skilled worker and some unskilled members. The optimal immigration policy which maximizes the per capita steady-state consumption of the host country is derived. We show that optimal immigration policy can reduce the steady-state skilled labour ratio. More interesting still, contrary to the widespread belief that immigration of skilled workers hurts local skilled workers, it is the unskilled local workers whose interests are threatened by optimal immigration policy.     

Growth,income distribution and unemployment in a two-sector economy

We build a two-sector general equilibrium growth model with capital-intensive consumption goods and a labour-intensive investment goods sector to investigate the coexistence of growth and unemployment. The model uses heterogeneity in saving behaviour, introduces an effective demand problem, has full employment of capital with input non-substitutability and shows that the aggregate labour employment is determined by available capital along with commodity market equilibrium. The long-run growth may not be balanced, and under biased growth, the level of unemployment may monotonically increase or decrease over time, or may first increase (decrease) and then decrease (increase). Such possible unemployment paths help us tightly define “jobless growth”.     

Industrial Policy, FDI and Employment: Still ‘Missing a Strategy’

This paper contrasts the effects of trade, inward FDI and technological development upon the demand for skilled and unskilled workers in the UK. By focussing on industry level data panel data on smaller firms, the paper also contrasts these effects with those generated by large scale domestic investment. The analysis is placed within the broader context of shifts in British industrial policy, which has seen significant shifts from sectoral to horizontal measures and towards stressing the importance of SMEs, clusters and new technology, all delivered at the regional scale. This, however, is contrasted with continued elements of British and EU regional policy which have emphasised the attraction of inward investment in order to alleviate regional unemployment. The results suggest that such policies are not naturally compatible; that while both trade and FDI benefit skilled workers, they have adverse effects on the demand for unskilled labour in the UK. At the very least this suggests the need for a range of policies to tackle various targets (including in this case unemployment and social inclusion) and the need to integrate these into a coherent industrial strategy at various levels of governance, whether regional and/or national. This has important implications for the form of any ‘new’ industrial policy.     

Minimum wage,unemployment and international migration

"The link between immigration and unemployment among the native workers of the host country is examined within a model which distinguishes individuals in terms of their ability to perform services in the labor market. An inflow of foreign workers is found to have an ambiguous effect on the level of income received by the native factors of production. This is in sharp contrast to the findings that immigration improves welfare in a fully employed host country and that it unambiguously lowers welfare in a minimum-wage economy with homogeneous labor."     

双重市场分割、资本深化与劳动深化——对中国经济高增长伴随高失业现象的解释

中国经济在高速增长的同时出现了高失业的反常现象,有学者提出资本过度深化是经济增长就业弹性低的主要原因。但中国是一个劳动力资源非常丰富而资本比较稀缺的国家,不可能在所有的领域都出现资本过度深化。本文认为,城镇国有企业出现的资本深化和中小民营企业出现的劳动深化都会抑制企业对劳动力的需求,从而加剧失业。     

TRAINING AND LABOUR MARKET SEGMENTATION

A two period model of the training decision is analysed using a human capital approach. The segmented labour market model where training opportunities distinguish entrants is compared with a competitive structure with homogeneous entrants. The main conclusions in the paper are the clear effects of training wages and the different effects in the two market structures of both wages and employment prospects in the unskilled market on training.     

Trade,Technical Change,and Labour Market Adjustment

This paper empirically examines three possible reasons for the high and rising unemployment of low‐skilled employees in Germany: (i) an upsurge in inter‐industry trade, (ii) a skill‐biased technical change, and (iii) a failure of labour market adjustment. The empirical analyses indicate that an exogenous wage‐setting process as well as a bundle of factors, including a skill‐biased technical and structural change, have contributed to the decline in relative demand for low‐skilled employees in Germany. Thus, economic policy in Germany should focus on improving the employability of workers in the lower segment of the labour market and on raising the adjustment flexibility, above all the flexibility of the wage structure, of the German labour market.     

Employee training and human capital in Taiwan

Although globalization, liberalization and the development of the network economy have undoubtedly enhanced the competitiveness of the Taiwanese economy, with the island's citizens benefiting enormously from lower prices on a wide range of products, the downside has been the obvious increase in unemployment, and the accompanying instability of employment amongst the island's remaining workforce. Policies adopted by the Taiwanese government to tackle this and improve human capital in the human resources development (HRD) process on the island, give rise to many questions, however, such as whether employee training programs can really provide Taiwan's workforce with sustainable employability and whether such programs can effectively reduce the probability of unemployment. They also raise the questions of whether employee training programs can help unemployed workers to shorten their unemployment period, thus reducing the overall number of structurally-unemployed workers, and whether these programs can ultimately lead to increases in overall income levels for successful trainees. These are the questions to be investigated in this paper.
