Trade, wages, and the political economy of trade protection: evidence from the Colombian trade reforms

Worker industry affiliation plays a crucial role in how trade policy affects wages in many trade models. Yet, most research has focused on how trade policy affects wages by altering the economy-wide returns to a specific worker characteristic (i.e., skill or education) rather than through worker industry affiliation. This paper exploits drastic trade liberalizations in Colombia in the 1980s and 1990s to investigate the relationship between protection and industry wage premiums. We relate wage premiums to trade policy in an empirical framework that accounts for the political economy of trade protection. Accounting for time-invariant political economy factors is critical. When we do not control for unobserved time-invariant industry characteristics, we find that workers in protected sectors earn less than workers with similar observable characteristics in unprotected sectors. Allowing for industry fixed effects reverses the result: trade protection increases relative wages. This positive relationship persists when we instrument for tariff changes. Our results are in line with short- and medium-run models of trade where labor is immobile across sectors or, alternatively, with the existence of industry rents that are reduced by trade liberalization. In the context of the current debate on the rising income inequality in developing countries, our findings point to a source of disparity beyond the well-documented rise in the economy-wide skill premium: because tariff reductions were proportionately larger in sectors employing a high fraction of less-skilled workers, the decrease in the wage premiums in these sectors affected such workers disproportionately.     

Mind the Gender Wage Gap – the Impact of Trade and Competition on Sectoral Wage Differences

This paper examines differences between women’s and men’s wages in 18 selected OECD countries in the period 1970 to 2005. The study is based on 12 manufacturing sector‐ and skill‐specific sets of panel data on the gender wage gap. We apply a system generalised method of moments (GMM) estimator to the extended version of the conditional gender wage gap convergence equation, controlling for sector concentration and industry‐specific measures of openness using a difference‐in‐difference approach: trade‐affected concentrated sectors versus trade‐affected competitive sectors. The results indicate that: (i) an increase in sector concentration is associated with wage gap growth; (ii) both import and export penetration are associated with a reduction of the high‐skill gender wage gap growth in concentrated industries; (iii) there is evidence of a widening impact of trade on the medium and low‐skill occupational gender wage gap growth in less competitive industries; (iv) institutional regulations of the labour market have an impact on the development of the gender wage gap: for highly‐skilled labour an increase in labour market regulation raises the growth of the gender wage gap, while for medium‐ and low‐skilled workers, it lowers it.     

Multi Fibre Arrangement and Wage Inequality: Firm and State‐level Evidence from India and a Theoretical Model

The phased elimination of Multi Fibre Arrangements (MFA) for textile and apparel has been one of the most compelling trade policy reforms that removed a system of bilateral quotas. The reform brought in significant changes in the industrial structures for exporters from the south, including India. Has the labour‐intensive high‐employment textile and clothing industry in India benefited from this global move towards freer trade? For India, the industry has witnessed unprecedented market concentration of export‐oriented firms. Firm‐level empirical estimate illustrates that workers in the export‐oriented firms in India are adversely affected due to withdrawal of quota. Accumulation of net fixed assets and growth of sales impart positive impact on firm‐level wages that cannot outweigh negative impact due to fall in exports. We also find negative impact of profit on aggregate wage bill for the industry with firms spread over 11 major states in India. We show that the mean deviation of industry‐level wage is positively and significantly associated with mean deviation of the number of factories at the state level and negatively with profit. Finally, a brief analytical exercise obtains conditions under which joint withdrawal of quota and import tariff could raise the aggregate labour income in developing countries, in general.     

Trade,Technology and Human Capital: Stylised Facts and Quantitative Evidence

Stylised evidence on trade, total factor productivity (TFP) and skill intensity of the labour force is presented. Features emerging as salient are: growing trade in technology‐intensive products from the industrialised nations to the relatively laggard nations leads to embodied technology diffusion; the technology‐intensive sectors have larger shares of skilled workers; countries experiencing TFP growth usually have higher levels of educational attainment; also, the skilled labour payment share for a sector is positively associated with that sector’s regional trade share. These facts together help explain why endowment of more skilled labour facilitates absorption of technology ferried via trade.     

THE WAGE–WAGE‐ . . . ‐WAGE–PROFIT RELATION IN A MULTISECTOR BARGAINING ECONOMY

The equalization of profit rates across industries subject to firm‐level bargaining over wages generates an interindustry wage structure with higher wages in capital‐intensive sectors. The familiar inverse wage–profit relation gives way to a wage–wage‐ . . . ‐wage–profit surface on which the profit rate can vary directly with the wage paid in an individual industry. Institutional changes that decrease workers' bargaining power and increase the incomes of the unemployed tend to compress the wage distribution; these changes draw political support from cross‐class coalitions of low‐wage workers and capital‐intensive firms. Some capital‐using, labor‐saving technical changes that raise capitalists' profits in current prices lower the equilibrium profit rate.     

Trade Liberalisation and Poverty: What are the Links?

This paper asks whether a developing country's own trade liberalisation could translate into increased poverty, and what information would be required to identify whether it will do so. It plots the channels through which such effects might operate, identifying the static effects via four broad groups of institutions – households, distribution channels, factor markets and government – and the dynamic issues of volatility, long–term economic growth, and short–term adjustment stresses. An increase in the price of something a household sells (labour, good, service) increases its welfare. Thus, the paper first explores the likely effects of trade liberalisation on the prices of goods and services, taking into account the distribution sector. Also critical is whether trade reform creates or destroys markets. Trade reform is also likely to affects factor prices – of which the wages of the unskilled is the most important for poverty purposes. If reform boosts the demand for labour–intensive products, it boosts the demand for labour and wages and/or employment will increase. However, not all developing countries are relatively abundant in unskilled labour and trade can boost demand for semi–skilled rather than unskilled, labour. Hence poverty alleviation is not guaranteed. Trade reform can affect tariff revenue, but much less frequently and adversely than is popularly imagined. Even if it does, it is a political decision, not a law of nature, that the poor should suffer the resulting new taxes or cuts in government expenditure. Opening up the economy can reduce risk and variability because world markets are usually more stable than domestic ones. But sometimes it will increase them because stabilisation schemes are undermined or because residents switch to riskier activities. The non–poor can generally tide themselves over adjustment shocks from a liberalisation, so public policy should focus on whether the initially poor and near temporary, setbacks. The key to sustained poverty alleviation is economic growth. There is little reason to fear that growth will not boost the incomes of the poor. Similarly, while the argument that openness stimulates long–run growth has still not been completely proven, there is every presumption that it will.     

Economic Implications of WTO Negotiations on Non‐agricultural Market Access

The economic implications of current WTO negotiations are likely to be far reaching. The World Bank and UNCTAD estimate annual global gains in agriculture and non‐agricultural products (including fish) of about $70−150 billion each under various scenarios and technical assumptions. Liberalising trade in services could be even more important, especially if agreement were reached to facilitate the temporary movement of labour (Mode 4 under the General Agreement on Trade in Services, GATS). Some qualifications, however, are in order. First, gains are likely to be spread unevenly across countries and across sectors; and, second, short‐term adjustment costs might precede long‐term gains. Much depends on how ambitious liberalisation is and on policies to facilitate adjustment. This paper examines the Doha mandate in non‐agricultural market access (NAMA) and the current state of the WTO negotiations, in particular some key proposals being considered at the December 2005 Ministerial Meeting in Hong Kong. We analyse various scenarios and their implications for trade, welfare, output, employment, revenues and preferences, as well as the distributional effects across countries and sectors. We note possible adjustment problems related to balance of payments and structural adjustment, as well as revenue and preference losses. These suggest the need for ‘aid for trade’ to help developing countries realise gains possible from WTO negotiations.     

Labour market characteristics and surviving import shocks

This paper investigates whether different labour market characteristics amplify or dampen the local labour market impacts from Chinese import competition exposure. I exploit state‐level variation in initial, pre‐shock labour market characteristics and regional variation across local labour markets in exposure to Chinese imports for identification. I find that local labour markets in states with higher union density experience more severe adverse consequences as a result of increased import exposure. Conversely, higher initial minimum wages help mute the negative impacts of the China shock. I also provide some evidence that exceptions to employment‐at‐will legislation can affect employment responses to increased Chinese imports. Finally, examining all policies together in an index, I show that higher levels of policies intended to benefit and protect workers can actually magnify the extent of the damage inflicted by import competition. My results suggest that initial labour market characteristics and policies can play an important role in understanding why local labour markets react differently to trade shocks.     

Outsourcing and the US Labour Market

There is worldwide concern about the vulnerability of the current labour force to displacement by future imported services. In the USA, some have suggested that as much as one‐third of the workforce might be vulnerable to such outsourcing. However, the labour market impacts of this displacement are difficult to assess using purely analytical or statistical approaches. In this paper, simulation methods are used to understand how sensitive the US economy and labour market are to increases in services imports. Specifically, the scenario examined assumes that the share of imported services in total employment increases from 0.8 per cent to 7.25 per cent over a time horizon in which workers are unable to change occupations. In response, it is found that all industries increase their use of imported services and their use of the composite input that is comprised of imported services and tradable labour. With the exception of legal workers, all workers in tradable occupations experience declines in their real wages. Demand for non‐tradable occupations labour rises in the industries that expand the most, while demand falls in shrinking industries. The non‐tradable occupations that are used intensively in the shrinking industries experience declines in real wages, while the real wages rise for workers in non‐tradable occupations used intensively in the expanding industries.     

Unilateral Liberalisation or Trade Agreements: Which Way Forward for the Pacific?

Empirical results show that, for the Pacific island states, a free trade agreement with developed countries provides more benefits followed by regional trade agreement within the Pacific and then unilateral tariff reduction. While the agricultural sector expands and the manufacturing sector declines in all scenarios, to avoid second‐best outcomes, developed countries need to go beyond the provision of aid for trade/development measures. For developing countries, the way forward with regional trade agreements is to carefully sequence them with regard to the different developed countries involved. This must be accompanied by domestic reform which is necessary but not sufficient for long‐term gains.     

Beyond Border Barriers: The Liberalisation of Services Trade in Tunisia and Egypt

Tunisia and Egypt have both recently undertaken significant steps toward trade reform. They have committed to a partnership agreement with the European Union. Both countries have also joined the WTO and are participating in Doha Round discussions on the liberalisation of non‐tariff barriers on both goods and services trade. These developments provide an interesting context within which to investigate not only the changes in welfare associated with reforms affecting the trade in goods, but also the impacts of services liberalisation. Using open‐economy computable general equilibrium models for both Tunisia and Egypt, this paper explores the reasons why structural differences in these two economies imply different opportunities and challenges with trade reform and services liberalisation. The gains from eliminating barriers at the border for goods trade are significantly greater for Tunisia than Egypt. Both countries, however, gain substantially from liberalisation of foreign direct investment in services. Furthermore, economic growth is more evenly distributed across sectors than with liberalisation of trade in goods alone. In addition to reporting on the impact of alternative policies on income, output, employment and trade, sector‐level effects are also considered.     

Foreign direct investment and inequality: Evidence from China's policy change

In this paper, we examine the impact of foreign direct investment (FDI) on local urban inequality in China. Specifically, we consider the FDI policy change as an exogenous shock on the local labour markets. We find that cities that have experienced a bigger policy change in promoting FDI between 1997 and 2002 are significantly more unequal in 2005. This pattern is mainly driven by the positive association between FDI liberalisation and skill premia. The result holds after we control for other policy changes, such as privatisation of state-owned enterprises, infrastructure and trade liberalisation. We then turn to investigate the mechanisms using firm and individual-level information. Our firm-level evidence shows that FDI firms not only hire relatively more high-skilled workers but also provide relatively higher wages to high-skilled workers compared to domestic firms. Moreover, the individual-level analysis shows that FDI has a significantly positive spillover effect on wages received by skilled workers employed by state-owned enterprises, but not wages of unskilled workers.     

Wage convergence and trade

We examine differences in wage rates across countries for workers employed in the same industry, distinguishing workers in the low, medium and high‐skill groups. These differences are large and show persistence over time. We ask, nonetheless, whether there is evidence of convergence, much as is done in studies of convergence in per capita income across countries. With our focus on the micro level, we expect convergence to reflect, at least in part, the degree of integration of a country or industry into the world economy and examine particularly the role of market integration and trade. Our results show strong evidence of convergence in a diverse sample of 39 countries, which includes most large economies whether rich or poor. The estimated convergence rate over the period from 1995 to 2008 is about 4% per year for workers in all skill groups, higher in the more integrated economies of the EU than in other economies without such open borders and lower in industries supplying services rather than manufactures. Also, we find evidence that the rate of growth of domestic output impacts positively on the growth of wages in an industry, providing a source for ongoing deviations from the convergence prediction.     

How and how far to liberalize a developing economy with informal sector and factor market distortions

Whether a liberalizing developing economy should implement the entire WTO-prescribed package, and to what extent this is expedient, are two important questions, especially because the available empirical evidence suggests that developing countries have been facing substantial adjustment costs in their endeavour to implement trade and investment reform. The present paper makes a humble effort to provide answers to the above questions in terms of a three-sector general equilibrium model with informal sectors. Welfare implications of three liberalization policies: inflow of foreign capital, tariff reduction and labour market reform, have first been analysed in a full-employment framework. Later, the paper has been extended into a Harris?–?Todaro framework with an urban informal sector and capital market distortion. We have shown that welfare consequences of a tariff reform and/or a policy of deregulating the labour market crucially depend on the presence and magnitude of foreign capital in the economy. It is argued here that unless a proper choice among different prescribed policies, compatible with the internal institutional, technological and trade-related characteristics, is made, drastic implementation of reform measures may produce counterproductive results for the welfare of the relevant country.     

Globalisation and Poverty in Latin America: Some Channels and Some Evidence

This paper provides an overview of the main mechanisms through which globalisation can affect poverty and household welfare in Latin America and presents supporting evidence from different case studies in the region. One case study explores the impacts of agricultural trade liberalisation in world markets on poverty in Argentina, with an emphasis on labour income effects via real wages. The second case study examines the impacts of CAFTA on net producers and net consumers among the indigenous population in Guatemala. The analysis explores short‐run impacts as well as medium‐run impacts as households adjust farm decisions. Finally, a last exercise is set up to study the role of agricultural liberalisation on wages, employment and unemployment when there are frictions in labour markets. These case studies show that the impacts of trade on developing countries are heterogeneous. In Argentina, there are gains from liberalisation of world agriculture and higher food prices. In Guatemala, instead, the indigenous population would benefit from lower food prices. It is clear that household adjustments and complementary factors are fundamental ingredients of any reasonable evaluation of the welfare impacts of trade reforms.     

Appreciating the Renminbi

International pressure to revalue China’s currency stems in part from the expectation that rapid economic growth should be associated with an underlying real exchange rate appreciation. This hinges on the Balassa–Samuelson hypothesis, which sees growth as stemming from improvements in traded sector productivity and associated rises in wages and non‐traded prices. Yet, despite extraordinary growth after the mid‐1990s China’s real exchange rate showed no tendency to appreciate until after 2004. We use a dynamic general equilibrium model to simulate the economy and show that, during this period, trade reforms and a rising national saving rate were offsetting forces in the presence of elastic labour supply. We then examine the possible determinants of the striking transition to real appreciation thereafter, noting mounting evidence that an improved rural term of trade has tightened China’s labour market. We show that should the Chinese government bow to international pressure by appreciating the renminbi either via an extraordinary monetary contraction or via export disincentives, the consequences would be harmful for both Chinese and global interests.     

The Pathological Export Boom and the Bazaar Effect: How to Solve the German Puzzle

Germany is the laggard of Europe, yet the country is world champion in merchandise exports. The paper tries to solve this theoretical and empirical puzzle by diagnosing a ‘pathological export boom’ and a ‘bazaar effect’. Excessively high wages defended by unions and the welfare state against the forces of international low‐wage competition destroy too big a fraction of the labour‐intensive sectors and drive too much capital and labour into the capital‐intensive export sectors, causing both unemployment and excessive value added in exports. Moreover, excessive wages induce too much outsourcing of upstream production activities, which implies that export quantities grow too much in relation to value added contained in exports. Finally, excessive wages cause capital flight resulting in a too large current account surplus.

The Skill Structure of Export Wage Premium: Evidence from Chinese Matched Employer–Employee Data

We study how the wage gap between exporting and non‐exporting firms (export wage premium) differs across skill groups, using unique matched employer–employee data from China. We find robust evidence that exporters pay relatively higher wages than non‐exporters to more educated workers. The differences in export wage premium across education groups are sizable. Further investigations show that the positive correlation between export wage premium and education is more pronounced in sectors with higher scope for quality differentiation. This is consistent with the theory that exporters produce relatively higher quality goods which require relatively higher quality skilled workers.     

The Effects of Globalisation on the US Labour Mark'et: Service Sectors Considered

How has globalisation affected employment and wages in the United States? Existing studies largely ignore the intersector labour movement between the manufacturing and service sectors by focusing only on the intrasector movement within the manufacturing sector. However, by decomposing the aggregate labour demand in the United States, we find that the intersector movement is more substantial than intrasector movement. Motivated by the decomposition results, this study presents a three‐sector model that includes a manufacturing sector and two service sectors at varying skill intensities. The model shows that offshoring might translate into smaller‐than‐expected wage changes because of the intersector labour movement. In line with the theoretical predictions, two notable empirical results are presented. First, an occupation's exposure to offshoring has non‐significant, albeit negative, effects on wages. Second, the more an occupation is exposed to offshoring, the lower its employment in the manufacturing sector as a share of its total employment. Furthermore, these effects are larger for more routine occupations or those requiring less education.
