Trade patterns,unemployment and growth

This paper analyses the implications of a minimum wage in an open economy two-sector model where the effect of growth on trade and unemployment is explicitly determined. The first-best policy is a wage subsidy to all employment while the second-best policy is a production tax cum subsidy. In the absence of policy intervention it is shown that growth in the short run results in decreasing unemployment for the home country if it is specialized in consumption goods or incompletely specialized provided that the minimum wage is binding. If the economy is specialized in investment goods, then unemployment may increase initially but as growth continues the minimum wage no longer remains binding and full employment is restored. In the long run by examining the dynamic interaction between trade and growth it is possible for the economy to be incompletely specialized with unemployment. If the economy specializes in consumption goods, it is possible for the economy to attain full employment.     

Education bias of trade liberalization and wage inequality in developing countries

The aim of this article is to examine the impact of increased trade on wage inequality in developing countries, and whether a higher human capital stock moderates this effect. We look at the skilled–unskilled wage differential. When better educated societies open up their economies, increased trade is likely to induce less inequality on impact because the supply of skills better matches demand. But greater international exposure also brings about technological diffusion, further raising skilled labour demand. This may raise wage inequality, in contrast to the initial egalitarian level effect of human capital. We attempt to measure these two opposing forces. We also employ a broad set of indicators to measure trade liberalization policies as well as general openness, which is an outcome, and not a policy variable. We further examine what type of education most reduces inequality. Our findings suggest that countries with a higher level of initial human capital do well on the inequality front, but human capital which accrues through the trade liberalization channel has inegalitarian effects. Our results also have implications for the speed at which trade policies are liberalized, the implication being that better educated nations should liberalize faster.     

The Winner’s Curse of Human Capital

We extend a model developed by Evans and Jovanovic (1989) to explain when start-ups are credit constrained. We show that the magnitude of the credit constraint is conditioned by the relative productivity of human capital in both wage work and self-employment. The effect of predicted household income on start-up capital is used to indicate the existence of financial constraint. Empirical analysis reveals that entrepreneurs with high human capital have both greater financial wealth and greater levels of start-up capital pointing to the endogenous nature of credit constraints. High human capital relaxes financial constraints, apparently due to greater productivity of human capital in wage work than in self-employment. Those who are the least likely to be credit constrained in self-employment are those that are least likely to switch into self-employment,and vice versa.     

SCALE‐INDEPENDENT TECHNOLOGICAL‐KNOWLEDGE BIAS,HUMAN‐CAPITAL ACCUMULATION AND GENDER INEQUALITY

We present a dynamic, non‐scale general‐equilibrium model with female and male human capital where Schumpeterian R&D and human‐capital accumulation are the engines of growth and gender wage inequality. Gender wage inequality is encouraged by changes in relative supply and relative demand of both human‐capital types. Relative supply restricts the levels of employed human capital. Relative demand is affected by the technological‐knowledge bias, which is driven by the price channel and is affected by human‐capital accumulation. In particular, the female‐premium per unit of human capital and per worker increases when the observed discrimination against women decreases or is removed.     

The welfare effects of illegal immigration

"This paper extends the work of Ethier on illegal immigration by examining the optimal level of enforcement for the labor-importing country in a two-country model and by considering the effects of allowing capital mobility. We derive a formula for the optimal level of enforcement against firms that hire illegal workers, and show that the presence of enforcement costs makes the policy less efficient than a wage tax. With capital mobility, foreign workers gain from an increase in enforcement in the home country because capital is driven out of the home country."     

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.     

Distributive Policies and Economic Growth: An Optimal Taxation Approach

In an infinite‐horizon endogenous growth model a capital income cum investment subsidy tax is considered to investigate if distribution of income towards the non‐accumulated factor of production (labour) retards growth and if capital income taxes are bad instruments to finance investment subsidies. The paper identifies conditions under which the tax scheme is better for growth than other distorting tax schemes. In the model a pro‐labour government acts growth maximizing and distributing income towards labour raises growth. A pro‐capital government's preferred policy is not growth maximizing under the tax scheme, but may generate higher growth than its optimal policy under other tax schemes.     

Visualization service investment strategies for a self-operated fresh agricultural product e-tailer

Motivated by the fact that numerous fresh agricultural product e-tailers utilize the visualization technology to improve service quality, this paper examines visualization service investment strategies for a fresh agricultural product e-tailer. A supply chain comprised of one manufacturer and one self-operated e-tailer is constructed. We first investigate two service investment strategies in the game theory model: the manufacturer investment and the e-tailer investment. Our analysis reveals that there are two investment cases in the supply chain: one member intends to the service investment (a “win-win” situation) and neither is willing to offer the service (a “lose-lose” dilemma). Then we extend the theory model. The impacts of consumer preference heterogeneity, demand uncertainty and consumer preference for the product quality difference on the investment strategies are explored by the method of multi-agent modelling. We find that: (i) when consumer preference heterogeneity is small, the e-tailer should invest in the service; (ii) if consumer preference or demand uncertainty is moderate, it is difficult to reach an agreement between two players. Further, the government subsidy factor is considered. The issue of how the government subsidy affects service investment strategies is discussed. In fact, it is not necessary to provide a subsidy all the time. Only when the free-riding behavior happens, the government should grant a moderate amount of subsidy to coordinate the supply chain members. An excessive subsidy hurts two sides’ benefits instead.     

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.     

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.     

Conditions for linearity of the wage curve

For a given technique, the wage-rate of profit curve is linear in one-sector models. In multisector models, Wicksell effects appear and some paradoxes in capital theory are linked to the complex shape of the wage curve. We study the conditions ensuring the linearity of the curve for a bisector model and for models satisfying a specific rank condition.     

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.     

城市经济转型时期人力资本回报率研究

基于Mincer基本模型和扩展模型的估算结果显示 ,中国城市地区的教育回报率比其他发展中国家的平均水平低 ,但这一回报率在不断上升 ;职工工资收入达到最高水平所需工作的年限在下降 ,工作年限的边际回报率在下降 ,尤其是女性工作年限的边际回报率下降速度更快。在 1986 /1987年 ,广东城市职工平均工资收入比湖南和四川高出 30 % ,而在 1993/1994年 ,广东城市职工平均工资收入比湖南和四川高出 70 % ,表明地区收入不平等的现象在扩大。令人费解的是 ,广东省的教育回报率并不高 ,尽管在这期间广东省男女两性的工作经验回报率大大下降。文章还发现 ,无论是工资性别歧视 ,还是职业性别歧视都似乎存在于中国城市的劳动力市场中     

Does globalisation affect the shadow economy?

We investigate the impact of globalisation on the shadow economy using panel data for 119 countries. Our evidence suggests that globalisation matters in mitigating shadow development. More specifically, we find that political globalisation reduces the shadow economy, whereas economic and social globalisations have limited statistical support after controlling for important factors that affect the size of the shadow economy. Overall, these results are robust after accounting for an alternative measure of the shadow economy, outliers, endogeneity and alternative model specifications.     

资本品进口、资本技能互补与中国的相对工资差距

中国是资本品净进口国,资本品进口引致资本积累并通过资本与技能互补效应增加对熟练劳动力的相对需求,是影响熟练劳动力与非熟练劳动力之间相对工资差距的一个重要机制。文章实证检验了资本品进口与中国熟练劳动力的互补效应及其对中国相对工资差距的影响。研究结论表明：资本与技能互补效应在中国长期存在,资本品进口促进了中国的资本积累,并通过资本与技能互补效应提高了熟练劳动力的边际产出,增加了对熟练劳动力的相对需求,扩大了相对工资差距。然而,劳动力的相对数量效应和相对效率效应对中国不断扩大的相对工资差距的解释力不强。     

Testing a Goodwin model with general capital accumulation rate

We perform econometric tests on a modified Goodwin model where the capital accumulation rate is constant but not necessarily equal to one as in the original model (Goodwin, 1967 ). In addition to this modification, we find that addressing the methodological and reporting issues in Harvie ( 2000 ) leads to remarkably better results, with near perfect agreement between the estimates of equilibrium employment rates and the corresponding empirical averages, as well as significantly improved estimates of equilibrium wage shares. Despite its simplicity and obvious limitations, the performance of the modified Goodwin model implied by our results show that it can be used as a starting point for more sophisticated models for endogenous growth cycles.     

LABOUR SUBSIDIES: A NEW LOOK

This paper reexamines the case for subsidizing employment. One superficially promising approach, based on the idea that government cofinancing of unemployment benefits could induce firms to lay off too many workers in bad times, turns out to be an unsatisfactory argument for employment subsidies when worker-firm contracts are optimal. But efficiency wage explanations for unemployment offer considerable scope for a revenue-neutral combination of a specific labour subsidy and ad valorem wage tax. When pitched low enough, unemployment must fall under a wide set of conditions.     

Sectoral Technical Progress and Aggregate Skill Formation

Recent studies discuss micro-transmission mechanisms to measure spillover effects of MNC (Multinational Corporations) activity on human capital in host countries. We develop an aggregate transmission mechanism to show that technology deepening in advanced sectors affect economy-wide skill formation, not analyzed in previous studies. Sector-specific advanced technological input and borrowing from local capital market at preferential rates dampens rate of skill formation if local firms are more skill-intensive. Liberal trade policies applied only to MNC sector may lower traditional export if credit subsidy offered to MNCs is simultaneously withdrawn.     

台湾对大陆产品提高关税的理论模型分析——从要素收入分配扭曲效应出发的研究

台湾如果对大陆产品提高关税会扭曲岛内要素收入分配的格局。本文在一个使用两种生产要素资本和劳动并生产两种商品高技术产品和机制品的一般均衡模型中,考察短期内和长期内上述关税提高会对两种要素的收入产生怎么样的影响。本文的理论分析得出的结论是:就劳动的收入工资来说,短期内两个部门的工资都在提高,但长期内未被保护的高技术产品部门的工资反而会降低;就资本的报酬来说,短期内被保护部门机制品的资本报酬有所提高,而没有被保护部门的资本报酬反而会降低。因此,台湾提高进口关税的这种要素收入分配效应,不利于自己优势产业的发展,ECFA的实施有其经济学理念基础。     

Factor rewards and the international migration of unskilled labor: a model with capital mobility

"Conventional economic wisdom holds that the migration of unskilled labor from less developed countries to neighboring developed countries should be expected to narrow the wage gap between those countries, and thereby reduce the incentive for further migration. [The authors suggest that] if capital is mobile internationally this reasoning may be inappropriate. Instead, emigration of unskilled labor out of the less developed country provides an incentive for capital to leave the country, too. As a consequence, wage rates move in the same direction in each country, and the gap between wage rates across countries even may increase."
