Globalization and firm level adjustment with imperfect labor markets

In a model with search generated unemployment and heterogeneity on both sides of the labor market, exporting firms are bigger and pay higher wages than other firms. Moreover, there is imperfect persistence in the decision to export and liberalization increases the wage gap between high- and low-skill workers. Openness can increase aggregate productivity in export-oriented markets while generating within-firm productivity losses for the weakest firms. In contrast, openness can lead to within-firm productivity gains for the weakest firms in import-competing industries.     

劳动禀赋结构和技术效应结构——贸易与工资差距研究范式新探

在回顾文献基础上,本文梳理出贸易影响工资差距的机制,认为在劳动供给结构不变的前提下,工资差距决定于劳动需求结构变动,而劳动禀赋结构和技术效应结构是研究两者关系的重要范式。劳动禀赋结构模型是在两国生产两种产品且技术水平相同的框架下,贸易品由于劳动禀赋结构不同,导致单位成本产出水平变动,进而影响劳动需求结构和工资差距;而技术效应结构模型则是在两国生产一种产品且技术水平不同的框架下,贸易品由于技术效应结构不同,导致相对工资和劳动需求关系曲线变动,进而影响劳动需求结构和工资差距,而且直接效应和间接效应的传导机制有很大差别。     

Welfare implications of trade liberalization and fiscal reform: A quantitative experiment

This paper studies the welfare implications of revenue-neutral trade liberalization and fiscal reform programs for developing economies using a multi-sector dynamic general equilibrium model of a small open economy. We analyze how different combinations of tariffs – on imported consumption goods, intermediate inputs, and capital goods – and taxes – on consumption, labor income and capital income – affect the transitional and long-run welfare. We report three main findings. First, trade liberalization programs financed by consumption and labor income taxes tend to result in substantial welfare gains, but financing the lost tariff revenue through capital income taxes can have an adverse impact on welfare. Second, a significant fraction of welfare changes is due to transitional effects stemming from the allocation of resources in response to changes in tariffs and taxes. Third, trade liberalization and fiscal reform programs often translate into much larger welfare gains in countries that are more open to international financial markets.     

贸易自由化对中国城镇劳动力市场性别歧视的影响

贸易自由化既可缩小也可扩大性别工资差。绝大多数实证研究,例如Oosdendorp(2004),都采用的是较宏观的行业加总数据,并着重于职业性别工资差。然而,行业加总的职业工资不能控制教育水平和经验变量,因此很难判断性别工资差的变化到底来自个人特征因素还是贸易自由化。文章运用中国城镇居民家庭的微观数据,运用difference-in-difference的方法,在消除了不随时间改变的固定效应和随时间变化的系统冲击的基础上,检验了1988年到1995年中国第一次贸易自由化兴起时期,贸易开放度的变化对不同教育水平的性别工资差的影响。结果显示,这一时期贸易开放度和性别工资差之间的相互关系主要来源于进口开放度的变化:随着进口开放度的上升,低教育人群的性别工资差显著扩大,而高教育人群的性别工资差却呈现相反趋势。出口开放度的上升对低教育人群的性别工资差没有显著影响,但与进口开放度的上升一样,它缩小了高教育人群的性别工资差。     

Jobs and Exposure to International Trade within the Service Sector in Sweden

To establish in which service industries there is international trade (or it may potentially exist), we calculate locational Ginis for different industries. The basic idea is that from this measure of regional concentration of different activities within a country we can identify industries where there appears to be regional trade, and hence also a potential for international trade. Based on our method, we find that: (i) the number of employed in tradable service appears to be at least as large as in the manufacturing sector, (ii) tradable service is much more skill intensive than manufacturing, and (iii) lately, the employment in tradable service has increased substantially. We argue that the last mentioned result is consistent with the substantial growth of skilled labour in Sweden since the mid‐1990s (Rybczynski effect) and factors leading to increased relative demand for skilled labour. Particularly, increased competition from and offshoring to low‐wage countries seem recently to have had a considerable impact on the creation of skilled jobs and the displacement of less skilled jobs in the tradable sector in Sweden. Furthermore, we apply a similar method as for industries to identify tradable occupations. Using our classification of tradable industries and tradable occupations in a Mincer type wage equation, we find that workers in such industries and occupations receive a wage premia of 12–13 per cent.     

Good jobs, bad jobs, and trade liberalization

How do labor markets adjust to trade liberalization? Leading models of intraindustry trade (Krugman (1981), Melitz (2003)) assume homogeneous workers and full employment, and thus predict that all workers win from trade liberalization, a conclusion at odds with the public debate. Our paper develops a new model that merges Melitz (2003) with Shapiro and Stiglitz (1984), so also links product market churning to labor market churning. Workers care about their jobs because the model features aggregate unemployment and jobs that pay different wages to identical workers. Simulations show that, for reasonable parameter values, as many as one-fourth of existing “good jobs” (those with above average wage) may be destroyed in a liberalization. This is true even as the model shows minimal impact on aggregate unemployment and quite substantial aggregate gains from trade.     

Preference heterogeneity, wage inequality, and trade

We consider individuals who value product variety, and who can be skilled or unskilled as workers. Skilled people prefer to consume skill-intensive goods. We show that under plausible conditions an increase in the relative size of the skilled population increases the relative wage of skilled workers, thereby increasing wage inequality. In our two-country model of trade, an increase in the relative supply of skilled labor in either country increases the relative wage of skilled workers, and hence increases inequality in both countries.     

最低工资对低收入群体的“增收”和“保基本”效果分析——以广州市数据为例

作为政府规制劳动力市场工资收入分配的唯一法定收入标准，最低工资是保障劳动者特别是低收入劳动者取得劳动报酬合法权益的重要手段，也是国家“提低、扩中、控高”收入分配制度改革政策中“提低”的主要措施之一。本文以广州市低收入宏观数据及微观流动人口数据为例，立足于评估最低工资调整对劳动者“增收”和“保基本”的效果，旨在分析最低工资调整是否满足了劳动者最基本的生活需求及对低收入群体增收效应的异质性差异如何。研究结果表明，最低工资标准基本能保障最底层收入家庭基本生活，并且最低工资对低收入群体工资存在正向效应，且对于男性、30岁以下、最低工资标准附近收入等组别的收入效果更为显著，同时存在对收入的溢出效应。     

Labor demand and trade reform in Latin America

Trade liberalization is thought to result in higher own-wage elasticities of labor demand, particularly for unskilled labor, with adverse implications for both labor market volatility and wage dispersion. The paper first argues that theoretically the link between liberalization and labor-demand elasticities is less clear than has previously been asserted. It then uses dynamic panel techniques to estimate labor-demand relations for manufacturing establishments in Chile, Colombia, and Mexico across periods of trade policy reform. The results do not strongly support the hypothesis that trade liberalization has a direct impact on own-wage elasticities.     

Does services liberalization benefit manufacturing firms?: Evidence from the Czech Republic

While there is considerable empirical evidence on the impact of liberalizing trade in goods, the effects of services liberalization have not been empirically established. This study examines the link between services sector reforms and the productivity of manufacturing industries relying on services inputs. Several aspects of services liberalization are considered, namely, the presence of foreign providers, privatization and the level of competition. The results, based on firm-level data from the Czech Republic, show a positive relationship between services sector reform and the performance of domestic firms in downstream manufacturing sectors. Allowing foreign entry into services industries appears to be the key channel through which services liberalization contributes to improved performance of manufacturing sectors. This finding is supported by evidence that foreign acquisitions of Czech services providers result in profound changes in the labor productivity and sales of acquired firms. As most barriers to foreign investment today are not in goods but in services sectors, the findings of this study may strengthen the argument for reform in this area.     

Dynamic analysis of a disequilibrium macroeconomic model with dual labor markets

We extend the general disequilibrium model of Malinvaud (1980) by using dual labor market theory. By considering two tiers of workers, we find that while the duality of the labor market expands an equilibrium regime in the short term, it does not always keep an equilibrium in the medium term. In the medium term, the business cycle converges toward a disequilibrium regime unless the goods market is potentially in equilibrium. Employment and wages at the steady state are affected by the size of the government expenditure, and the stability of wage bargaining is only a sufficient condition of the local stability of our dynamic system. Therefore, involuntary unemployment can be remedied only when goods demand is sufficiently large.     

The Limits to Wage‐Led Growth in A Low‐Income Economy

Neo‐Kaleckian literature has actively debated whether growth is wage‐ or profit‐led in capitalist economies. However, existing studies tend to ignore the non‐tradable sector and heterogeneity within the tradable sector. This article shows that incorporating these features renders wage‐led growth in an open developing economy unfeasible in the traditional (Kaleckian) sense of the term. This result—which follows even if one sets aside the competitiveness considerations generally seen as impeding such growth—occurs due to the presence of a homogeneous goods‐producing tradable sector that sets the ceiling to steady‐state growth. A corollary, in light of findings from the ‘new new trade theory’ literature, is that increasing South‐South trade may tend to narrow room for wage‐led growth regardless of the other desirable effects of higher wages.     

Trade liberalization and the allocation of labor between households and markets in a poor country

We consider the relationship between relative price changes and the allocation of labor between households and the formal wage labor market in the context of Vietnam's liberalization of its rice trade in the 1990s. Many individuals in poor economies work within their own household rather than in formal labor markets. We find that larger rice price increases in a community are associated with declines in hours adults devote to work within the household and increases in time spent in the wage labor market. We also observe increased specialization in household economic activities accompanying these shifts in hours towards wage work. Our results are consistent with the idea that a growth in the extent of the market shifts production and labor from households to markets during development, thereby inducing gains from specialization. Thus, the reallocation of labor between households and markets in response to a trade liberalization might be an important component in understanding the link between trade and growth in very poor economies, currently the focus of the Doha WTO negotiation round.     

贸易自由化对工资差距的影响及作用机制--基于中国制造业企业的实证研究

本文利用世界银行的中国企业调查数据分析贸易自由化对工资差距的影响,结果表明贸易自由化显著提升企业内工资差距。企业进口投入品的行为使其内部普通员工的最高与最低工资之比提高约50％,总经理与中层经理的工资比提高约30％,中层经理与普通员工的工资比提高约12％－20％。进一步分析表明,自由贸易使企业对高技能劳动力的需求更大,更倾向于采用绩效工资、进行研发投资、提供员工培训和使用计算机,这些因素均导致工资差距的上升。     

Escaping a protectionist rut: Policy mechanisms for trade reform in a democracy

This paper analyzes the dynamics of trade policy reform under democracy. In an overlapping generations model, heterogeneous agents may acquire skills when young thereby determining the skill composition of their cohort. Current and anticipated trade policies influence education decisions and thus voters' trade policy preferences. We show that there may exist two political steady states: one protectionist and one liberal. Transition from the former to the latter can be achieved by government announcements, temporary educational subsidies, or tariff liberalization by trading partners, but generally not by transfer payments to adversely affected workers. We find additionally that reform is politically feasible only if the proposed liberalization is sufficiently large, suggesting that radical reform may be necessary for escaping a protectionist political rut.     

How wages and employment adjust to trade liberalization: Quasi-experimental evidence from Austria

We study the response of regional employment and nominal wages to trade liberalization, exploiting the natural experiment provided by the opening of Central and Eastern European markets after the fall of the Iron Curtain in 1990. Using data for Austrian municipalities, we examine differential pre- and post-1990 wage and employment growth rates between regions bordering the formerly communist economies and interior regions. If the ‘border regions’ are defined narrowly, within a band of less than 50 km, we can identify statistically significant liberalization effects on both employment and wages. While wages responded earlier than employment, the employment effect over the entire adjustment period is estimated to be around three times as large as the wage effect. The implied slope of the regional labor supply curve can be replicated in an economic geography model that features obstacles to labor migration due to immobile housing and to heterogeneous locational preferences.     

Can compensation save free trade?

When the median voter loses from trade reform, liberalization is blocked. Allowing the electorate to vote for compensatory subsidies may reverse this outcome. However, the order of the agenda may matter. The winners who pay the compensation may be sufficiently powerful to block compensation if trade is first liberalized. Seeing the inevitable outcome of sequential votes, the median voter realizes he will not be compensated for his losses and opposes liberalization. In contrast, liberalization can be achieved if compensation is placed first on the agenda. Finally, there is a significant chance that the least efficient compensation scheme will be chosen.     

Trade liberalization, wage inequality, and endogenously determined nontraded goods

We examine the boundary between traded and nontraded goods as a channel for trade to impact factor prices. In a two-country, two-factor, continuum-good model, tariffs generate a range of nontraded goods. A tariff reduction has a direct effect to expand a country’s import set and an indirect effect through terms of trade to expand its export set. We show that the export expansion can dominate the import expansion, raising the relative demand for the factor intensively used in production. The result is useful in explaining observed rising wage inequality in developing countries following trade liberalization.     

Migration and trade: Theory with an application to the Eastern-Western European integration

The remarkable increase in trade flows and in migratory flows of highly educated people are two important features of globalization of the last decades. This paper extends a two-country model of inter- and intra-industry trade to a rich environment featuring technological differences, skill differences and the possibility of international labor mobility. The model is used to explain the patterns of trade and migration as countries remove barriers to trade and to labor mobility. We parameterize the model to match the features of the Western and Eastern European members of the EU and analyze first the effects of the trade liberalization which occurred between 1989 and 2004, and then the gains and losses from migration which are expected to occur if legal barriers to labor mobility are substantially reduced. The lower barriers to migration would result in significant migration of skilled workers from Eastern European countries. Interestingly, this would not only benefit the migrants and most Western European workers but, via trade, it would also benefit the workers remaining in Eastern Europe.     

Productivity, terms of trade and the ‘home market effect’

This paper analyzes the international transmission and welfare implications of productivity gains and changes in market size when macroeconomic adjustment occurs both along the intensive margin of trade (changes in the relative price of existing varieties of tradable goods) and the extensive margin (creation and destruction of varieties). We draw a distinction between productivity gains that enhance manufacturing efficiency and gains that lower the cost of firms' entry and of product differentiation. Countries with lower manufacturing costs have higher GDP but supply their products at lower international prices. Instead, countries with lower entry costs supply a larger array of goods at improved terms of trade. Output growth driven by demographic expansions, as well as government spending, is associated with an improvement in international relative prices and firms' entry. While trade liberalization may result in a smaller array of goods available to consumers, efficiency gains from deeper economic integration benefit consumers via lower goods prices. The international transmission mechanism and the welfare spillovers vary under different asset market structures, depending on trade costs, the elasticity of labor supply, and consumers' taste for varieties.
