Wage Inequality,Increased Competition,and Trade Liberalization: Short Run vs Long Run

This paper examines the impact of increased competition and trade liberalization on skilled–unskilled wage inequality in the short run as well as the long run. It is shown that an increase in the number of firms in the producer services sector increases wage inequality in the short run even if the income shares of capital in the industrial and agricultural sectors were identical. A decrease in the services sector's fixed cost decreases wage inequality in the short run if the income share of capital in the agricultural sector is relatively large. Owing to the presence of external economies, a decrease in the services sector's fixed cost increases wage inequality in the long run. A decrease in import duty on the agricultural good increases wage inequality in the short as well as the long run but its effect in the long run is stronger due to the presence of external economies in the industrial sector.     

A nonlinear approach to the U.S.–Australia commodity trade and the J‐curve: Evidence from 123 industries

The application of nonlinear models and asymmetric analysis have recently proven to yield results that are superior to those of the linear and symmetric analysis. However, the new approaches in testing the J‐curve between Australia and the rest of the world or between Australia and her trading partners such as the United States did not yield any significant outcomes. Suspecting that those results suffer from aggregation bias, we apply new methods to the trade flows of 123 industries that trade between the United States and Australia and give evidence of an asymmetric J‐curve in 28 industries. Furthermore, we find short‐run asymmetric effects of exchange rate changes on the trade balance of almost all studies, short‐run impact asymmetric effects in 27 industries and significant long‐run asymmetric effects in 56 industries. Our findings are industry‐specific.     

An Empirical Analysis of Australian Labour Productivity

This study presents a model capturing sources of Australian aggregate labour productivity using annual time series data from 1970 to 2001. Labour productivity, or real output per hour worked, in this model is determined by real net capital stock in information technology and telecommunications (ITT), real net capital stock in the non-ITT sector, trade openness, human capital, the wage rate, international competitiveness, and the union membership rate. Given the lack of long and consistent time series data, multivariate cointegration techniques are inappropriate as the cointegration results will be sensitive to the lag length, the inclusion or exclusion of the intercept term or a trend in the cointegration equation and/or the vector autoregression (VAR) specification. Therefore, the Engle-Granger representation theorem and the Hausman weak exogeneity test have been employed to determine the short and long-term drivers of Australian productivity. Empirical estimates indicate that, in the long-term, policies aimed at promoting various types of investment, trade openness, international competitiveness, and the use of wage as a stimulant in a decentralised wage negotiation system, will improve labour productivity. In the short term, all the above variables except for human capital and labour reforms, which both need more time to evolve, determine productivity performance.     

Same Work,Different Pay? Evidence from a US Public University

Abstract

This study examines detailed data for faculty at a typical public research university in the United States between 1995 and 2004 to explore whether gender wage differentials can be explained by productivity differences. The level of detail – including the number of courses taught, enrollment, grant dollars, and number and impact of publications – largely eliminates the problem of unmeasured productivity, and the restriction to one firm eliminates unmeasured work conditions that confound investigations of wider labor markets. The authors find that direct productivity measures reduce the gender wage penalty to about 3 percent, only 1 percentage point lower than estimates from national studies of many institutions and with fewer productivity controls. The wage structure for women faculty differs markedly from the wage structure for men. Interpreted against the institutional features of wage setting for this population, the paper concludes that penalties for women arise at the department level.     

Trade Liberalization and Productivity Growth

This paper presents a trade model with firm‐level productivity differences and R&D‐driven growth. Trade liberalization causes the least productive firms to exit but also slows the development of new products. The overall effect on productivity growth depends on the size of intertemporal knowledge spillovers in R&D. When these spillovers are relatively weak, then trade liberalization promotes productivity growth in the short run and makes consumers better off in the long run. However, when these spillovers are relatively strong, then trade liberalization retards productivity growth in the short run and makes consumers worse off in the long run.     

Labour market discrimination and the macroeconomy

We measure the discriminatory ethnic and gender wage gaps in Georgia. Gender wage discrimination is larger than the ethnic wage discrimination. We use the estimated gaps in a general‐to‐specific vector autoregression framework to test for Granger causality between discrimination and growth, and estimate the long‐run effects of each variable on the other. Granger causality is found to be bidirectional, but it is only the net long‐run effect of discrimination on growth that is a large and highly significant negative effect. In the long‐run, a 10% increase in ethnic (gender) discrimination reduces economic growth by 3%–4% (8%–10%). Additionally, ethnic and gender wage differentials are found to be counter‐cyclical.     

‘Old’ Europe’s wage dynamics and trade imbalances: Is there a link?

No evidence is found that gains in relative labour productivity have had a positive effect on the trade balance/GDP ratio for the ‘old’ EU members (excluding Germany) from 1961 to 2014. Rising relative wage rate is shown to have had strong—and negative—effects on the trade balance/GDP ratio for the EU-14, at least in the longer run. It follows that external rebalancing may be achieved through a sufficiently strong fall in the relative wage rates, without productivity changes having a role to play. This is not to claim that the EU-14 (and its members suffering trade deficits in particular) ought to attempt the devastating policy of ‘internal devaluation’. A constructive alternative would be to achieve the fall in the relative wage rates through faster growth of German nominal wage rates. Whether that alternative is practicable is another matter. But it can be argued that without that alternative being followed the European Union will remain a stagnant area plagued by recurrent crises caused by imbalanced trade among its Member States.     

INTERNATIONAL COMPARISONS OF INTER-INDUSTRY WAGE DIFFERENTIALS

We use OECD data to examine inter-industry wage differentials (relative wages among industries) for 14 OECD countries over the period 1970–85. We find, first, that the industrial wage structures have shown remarkable stability over time in terms of rank order for all the countries in the sample. Second, despite their rank order stability, wage structures show a tendency to expand or contract. While the U.S. has shown increasing industry wage dispersion between 1970 and 1985, the pattern is very mixed for other countries. Unionization is a significant factor in explaining cross-country differences. Third, industry wage rankings show some evidence of becoming increasingly similar across nations over time, and this movement is associated with a convergence of per capita incomes. Fourth, industry wage differentials are positively related to an industry's productivity growth, output growth, capital intensity, and export orientation.     

Is there an export or import-led productivity growth in rapidly developing Asian countries? a multivariate VAR analysis

In contrast to cross-country studies, the paper investigates the relationships between trade and labour productivity for nine rapidly developing Asian countries in a time-series framework using a vector error-correction model. Independent tests on the long-run and short-run relationship between trade variables of exports and imports and productivity are conducted. The results suggest that trade has an important impact on productivity and output growth in the economy, however it is imports that provide the important?‘virtuous’?link between trade and output growth. The results indicate that exports and imports have qualitatively different impacts on labour productivity. The long-run result shows that there is no causal effect from exports to labour productivity growth for Hong Kong, Indonesia, Japan, Taiwan and Thailand; thereby suggesting that there is no export-led productivity growth in these countries. However, significant causal effects were found from imports to productivity growth, suggesting import-led productivity growth in India, Indonesia, Malaysia, Philippines, Singapore and Taiwan. In addition, the results indicate that imports tend to have greater positive impact on productivity growth in the long run.     

Mena Stock Markets Integration: Pre and Post Global Financial Crisis

This paper examines the short‐ and long‐run linkages in pre and post global financial crisis among Middle East and North Africa (MENA) stock markets, between MENA and Chinese stock markets and also between MENA and developed (United States and United Kingdom) stock markets. Results indicate that both long‐run co‐integration relationships and short‐run causal linkages among MENA stock markets increased in post‐crisis than that in pre‐crisis sub‐period. The degree of integration between MENA and Chinese stock markets increased in post‐crisis than pre‐crisis. We also find that the degree of integration between MENA and developed (United States and United Kingdom) stock markets increased in post‐crisis than that in pre‐crisis. The presence of increased linkages among MENA markets, and between MENA and Chinese stock markets and also between MENA and developed (United States and United Kingdom) markets has important implications for portfolio investors and policy makers.     

US–Indonesia trade at commodity level and the role of the exchange rate

Previous studies that assessed the impact of currency depreciation on inpayments and outpayments of Indonesia with her major trading partners did not find much significant results, especially in the trade with the United States. We wonder whether insignificant link between the real rupiah-dollar rate and Indonesia’s inpayments and outpayments with the United States is due to aggregation bias. To answer this question, we disaggregate the trade flows between the two countries by commodity and consider the sensitivity of inpayments of 108 US exporting industries and outpayments of 32 US importing industries from Indonesia. We find that most industries respond to exchange rate changes in the short run. In the long run, however, 32 inpayments schedule and 17 outpayments schedule are significantly affected. A 1% real depreciation of the dollar was found to improve US trade balance by 1.8%.     

实际外部财富、劳动生产率与人民币实际汇率——基于跨期一般均衡理论的实证研究

本文首先构建关于实际外部财富、劳动生产率、贸易条件与实际汇率关系的跨时一般均衡理论模型,然后利用1981-2009年相关时间序列数据,检验中国实际外部财富、贸易条件以及国内外两部门劳动生产率对人民币实际汇率的影响。结果表明,从长期看,中国实际外部财富的急剧攀升会引发人民币实际汇率快速升值;中国贸易部门相对非贸易部门劳动生产率上升会促使人民币实际汇率升值,而国外贸易部门相对非贸易部门的劳动生产率提高则会降低人民币实际汇率,净效应表现为劳动生产率并不能解释20世纪80年代以来人民币实际汇率的长期波动;中国贸易条件对人民币实际汇率的影响不明显。短期内,中国实际外部财富对人民币实际汇率的作用关系与长期一致。根据上述结论,本文提出了保持人民币实际汇率相对稳定的政策建议。     

Productivity Shocks and Real Effective Exchange Rates

This paper provides new insights into the relationship between exchange rates and productivity developments for European Economies. We focus on the question whether productivity changes have a long‐run impact on real effective exchange rates for a large number of European economies. Focusing on a sample period running from 1995 until 2013, we adopt a cointegrated vector autoregressive approach and distinguish between long‐run equilibrium, short‐run dynamics and long‐run impact of shocks. Our findings show that for several industrialized economies, real effective exchange rates and labor productivity are not related over the long‐run. A possible explanation for this result is that wage developments do not reflect increases in labor productivity to a large degree, which prevents a transmission to the real effective exchange rate through the price channel. The results for Central and Eastern European Countries are more encouraging since a positive impact of labor productivity on real effective exchange rate is frequently observed.     

The “export-import” effect and economic growth

This paper proposes that singular improvements in productivity and growth are a result of increased exports and imports, especially in the manufacturing sector, but that sustainable increases in growth can only emerge through industrial diversification. Trade liberalizations between Canada and the United States have caused a narrowing of manufacturing productivity differentials, a predominance of intraindustry trade, and a positive Canadian trade balance for manufactured end products and fabricated materials. Sustained growth, however, relies more on the diversification of the industrial structure. Toward this end, Canadian trade policies should: (1) concentrate productivity in the exportable, rather than importable, sectors, (2) rationalize and specialize between rather than within industries, (3) encourage two-way trade in each industry, (4) liberalize trade gradually to avoid interindustry disruptions, and (5) redirect job real- location funds toward worker retraining and firm-specific modernization programs.     

PRIVATIZATION IN CHINA: TECHNOLOGY AND GENDER IN THE MANUFACTURING SECTOR

This paper examines the impact of privatization on gender discrimination in China across firms with different technology intensities. Using a comprehensive firm‐level survey, the paper identifies gender wage‐productivity differentials by directly estimating the relative productivity levels of workers from the production function of firms. The panel structure of the survey is taken advantage of by following firms that were fully state‐owned in the initial year, and distinguishing them from firms that were later privatized. The main results show that privatization was associated with an increase in relative productivity of female workers in high technology industries, and a reduction in relative productivity of female workers in low technology industries. Time varying coefficient results suggest that the improvements in gender outcomes in high technology industries may not be maintained in the long run as the relative wage and productivity ratios tend to deteriorate, potentially due to low supply of highly educated female workers. At the same time, outcomes in privatized low technology industries increase over time, lowering the wage and productivity gaps between male and female workers. (JEL J16, J31, P20)     

Does trade openness affect long run growth? Cointegration,causality and forecast error variance decomposition tests for Pakistan

The study investigates the impact of trade openness on economic growth in the long run. We apply the ARDL bounds testing approach to test for a long run relationship and the augmented production function by incorporating financial development as an additional determinant of economic growth using the framework of Mankiw et al. (1992). The results confirm cointegration among the series. In the long run, trade openness promotes economic growth. The growth-led-trade hypothesis is vindicated by VECM Granger causality test. The causality is also checked by using the innovative accounting approach (IAA).     

International Trade,Technology, and the Wage Gap: Evidence from Granger‐causality Tests*

In this paper, we propose an alternative approach under which to examine the source of the increased wage gap between skilled and unskilled workers in US manufacturing. Rather than imposing the assumptions inherent in a given structural form, we posit a long‐run equilibrium relationship between international trade, technology, and the wage premium using a vector error‐correction model. We first test for the existence of a long‐run relationship using cointegration tests. If a cointegrating relationship is found, we then conduct tests on the direction of the long‐run relationship and of Granger causality. We apply our approach to each two‐digit and four‐digit SIC industry and find evidence in support of international trade being an important source of the wage gap. Our results suggest that it is premature to dismiss international trade as a possible suspect behind the rising wage premium.     

LABOR SUPPLY FACTORS AND ECONOMIC FLUCTUATIONS

We propose a new Vector Autoregressive identification scheme that enables us to disentangle labor supply shocks from wage bargaining shocks. Identification is achieved by imposing sign restrictions on the responses of the unemployment rate and the labor force participation rate to the two shocks. According to our analysis on United States data over the period 1985–2014, labor supply shocks and wage bargaining shocks are important drivers of output and unemployment both in the short run and in the long run. These results suggest that identification strategies used in estimated new Keynesian models to disentangle labor market shocks may be misguided.     

Asymmetric effect of exchange rate volatility on India's cross‐border trade: Evidence from global financial crisis and multiple threshold nonlinear autoregressive distributed lag model

This paper examines the asymmetric effect of exchange rate volatility on India's cross‐border trade with its major trading partners: Japan, Germany, the United States, and China. We extend previous studies in two ways. First, we examine whether global financial crisis changes the asymmetric effect of exchange rate volatility on India's cross‐border trade. Next, we divide exchange rate volatility into quintiles and examine the effect of each quintile on cross‐border trade by using the multiple threshold nonlinear autoregressive distributed lag (MTNARDL) model. Our findings from standard nonlinear ARDL (NARDL) indicate that the asymmetric relationship between exchange rate volatility and cross‐border trade changes as a result of global financial crisis. In addition, findings from MTNARDL indicate that in short‐run, exchange rate volatility symmetrically affects India's cross‐border trade with all sample countries whereas in long‐run it asymmetrically affects cross‐border trade. Overall, these findings are very important for policy implications and open a new dimension to exchange rate volatility and trade flows.     

Quantifying the Impact of Trade on Wages: the Role of Nontraded Goods

This paper uses an applied general‐equilbrium model to decompose the effects of changes in trade‐ and technology‐related variables between 1982 and 1996 in the United States on the wages of skilled and unskilled labor. The results indicate that trade‐related variables (tariff cuts, improvement in the terms of trade, and the increase in the trade deficit) had little impact on the widening wage gap. The major factor behind the rise in the skilled wage relative to the unskilled wage was differential rates of growth in skill‐biased technical change across sectors. The paper also highlights the role that nontraded goods play in explaining the wage gap. Finally, the paper presents estimates of how wages would change if the economy moved to autarky. The results show that expanding trade could actually reduce wage inequality, rather than increase it.
