Pay inequality and firm performance: evidence from matched employer–employee data

A large matched employer–employee data set for Sweden is used to test several predictions from tournament theory. For white-collar workers a positive and significant effect of intra-firm wage dispersion on profits and average pay is found, using various measures of wage dispersion. This result is robust for controlling for firm differences in human capital and firm fixed-effects as well as for instrumenting the wage dispersion variable to take into account endogeneity of wage dispersion. Using data on around 10?000 managers, a positive and significant association between pay dispersion and profits is also found for executives. Further results include a positive relationship between market demand volatility and wage dispersion, measured as coefficient of variation in managerial pay, and a negative effect of the number of managers (contestants) on managerial pay spread. The first two results are in accordance with predictions from tournament theory, while the last one is not.     

Segregation and gender wage gaps in the private and the public sectors: an analysis of Danish linked employer–employee data, 2002–2012

This paper examines the relation between segregation and the gender wage gap in the public and the private sectors in Denmark from 2002 to 2012. The analysis shows that male–female differences in the share of females in occupations, industries, establishments and job cells (occupations within establishments) constitute 46 % of the raw gender wage gap in the private sector, while segregation in the public sector accounts for as much as 63 %. Segregation thus plays a substantially more important role in accounting for the gender wage gap in the public sector than in the private sector. While the importance of segregation for wage formation decreased substantially in the public sector over time, it only decreased slightly in the private sector. Although the remaining gender wage gap, after controlling for segregation, is close to zero in the public sector, a substantial within-job cell differential remains after controlling for segregation in the private sector.     

Labour segregation and immigrant and native-born wage distributions in Spain: an analysis using matched employer–employee data

This article carries out an empirical examination of the origin of the differences between immigrant and native-born wage structures in the Spanish labour market. Special attention is given in the analysis to the role played by occupational and workplace segregation of immigrants. Legal immigrants from developing countries exhibit lower mean wages and a more compressed wage structure than native-born workers. By contrast, immigrants from developed countries display higher mean wages and a more dispersed wage structure. The main empirical finding is that the disparities in the wage distributions for the native-born and both groups of immigrants are largely explained by their different observed characteristics, with a particularly important influence in this context of workplace and, specially, occupational segregation.

Employer size–wage effects: evidence from matched employer–employee survey data in the UK

This paper employs a random sample of matched employer–employee data from the UK to test seven possible explanations for the positive relationship between employer size and pay. Individual wage equations show a large employer size–wage premium. We then control for a range of establishment-level variables, based on seven hypotheses typically advanced to explain this premium. Each establishment-level factor reduces the wage premium, but a sizeable premium nonetheless remains. In adjudicating on these hypotheses, we find a strong association between the internal labour market and the employer size–wage premium. This finding supports the theory that the employer size–wage effect may be due to the higher costs of turnover or monitoring in larger firms. However, we find contrasting effects for public versus private sector establishments.     

Trade and the environment: from a ‘Southern’ perspective

The relationship between free trade and the environment is one of the main issues of contention between environmental and ecological economics. Environmental economics assumes a positive relationship between free trade, economic growth and environmental policies. Environmental externalities may cause important damage. However, trade is not to be blamed for this. Instead, the fault lies with policy inadequacies at the national level. On the other hand, some ecological economists criticise the assumptions of environmental economics, especially the immobility of production factors and the positive correlation between income and environmental quality. They plead for measures to prevent deterioration of ‘Northern’ environmental standards in a ‘race to the bottom’ due to ‘ecological dumping” from the South. In this paper, we argue that neither environmental economics nor ‘Northern’ ecological economics take into account the structural conditions determining the international trade system. Based on some new empirical evidence on material flows, we stress the notion of environmental cost-shifting. If physical and political ecology perspectives are adopted, a ‘Southern’ approach to the trade-and-environment issue may arise.     

Innovation,imitation and multinationalisation in a North–South model: a theoretical note

We consider a dynamic general equilibrium product variety model of international product cycle with endogenous rate of imitation in the South; and find that a policy of strengthening intellectual property rights (IPR) protection in the South lowers the rate of product innovation, rate of multinationalisation and South–North relative wage if multinationalisation [or, foreign direct investment (FDI)] is the channel of production transfer. These results are significantly different from those obtained in the exogenous imitation model of Lai (J Dev Econ 55(1): 133–153, 1998). So a stronger IPR protection policy adopted by the South may not be interpreted as an incentive to encourage Northern FDI in the South and to raise the rate of innovation in the North.      

Short-selling constraints and stock-valuation pattern: a regime–event analysis

Employing a novel approach of integrating regime analysis with event analysis, we examine the overall valuation pattern of stocks that traverse the short-sale-ban and the no-ban regime, employing data from the Hong Kong market. Switching from the ban to the no-ban regime, stocks initially undergo net cumulative undervaluation and then revert to fundamental valuation. Switching from the no-ban to the ban regime, stocks initially experience net cumulative excessive overvaluation and then revert to permanent overvaluation. The amount of net cumulative undervaluation is greater than the amount of net cumulative excessive overvaluation. This documented overall pattern offers a broad perspective on short-sale constraints and stock valuation.     

Deviations from optimal corporate cash holdings and the valuation from a shareholder’s perspective

The trade-off theory of corporate cash holdings predicts that there is an optimal level of cash. We test the trade-off theory by investigating the relation between deviations from optimal cash holdings and the valuation of cash from a shareholder’s perspective. We decompose corporate cash holdings into the optimal level of cash and the deviations from the optimum. We find that the marginal value of cash for shareholders is higher when a change in cash moves corporate cash holdings towards the optimal level and that this relationship holds for both the above-optimal deviations and the below-optimal deviations. We conclude that the results are consistent with the prediction of the trade-off theory of corporate cash holdings.     

Economic liberalization and urban–rural inequality in India: a quantile regression analysis

We examine India’s urban–rural inequality in welfare in 1993–1994 and 2004, a period which coincides with the country’s economic liberalization reforms and rapid economic growth. Using real monthly per capita household consumption expenditure as our measure of welfare, we estimate quantile regressions to analyze the urban–rural welfare gap across the entire welfare distribution. While the urban–rural welfare gap was fairly convex across the welfare distribution in 1993–1994, it became more concave in 2004, with the gap narrowing for the lowest and highest quintiles and widening for the middle three quintiles. The urban–rural gap in returns to all levels of education widened substantially for the bottom four quintiles but became increasingly negative for the top quintile. Applying the Machado and Mata (J Appl Econom 20:445–465, 2005) decomposition technique to decompose the urban–rural welfare gap at each percentile, we find that for the bottom 40% of the distribution, differences in the distribution of covariates became less important while differences in the distribution of returns to covariates became more important in explaining the gap. The opposite was true for the top 40% of the distribution. Our analysis suggests that while the rural poor appear to be catching up with their urban counterparts in terms of labor market characteristics, ten years of economic reforms have intensified the urban–rural gap in returns to these characteristics. On the other hand, the rural rich lag even further behind the urban rich with respect to their labor market characteristics even though the urban–rural gap in the returns to these characteristics has diminished during the reform period. Future efforts to generate urban–rural equality may require policies that seek to equalize returns to labor market characteristics between the two sectors at the lower half of the distribution and improve rural labor market characteristics at the top half of the distribution.     

Disability and earnings: Are employer characteristics important?

We use matched employee–employer data from Britain to assess the influence of disability-specific workplace policies and practices on the earnings of disabled workers. The presence of equal opportunities policies increases the relative wages of disabled workers, but this is partially offset by the negative influence of workplace accommodations.     

Urbanization and urban-rural inequality in china: a new perspective from the government��s development strategy

This paper offers a novel explanation for the lower urbanization rate and great urban-rural inequality in China. Our study reveals that, heavy-industry-oriented development strategy will result in lower urbanization rate and higher urban-rural inequality. The greater the degree of heavy-industry-oriented development strategy is, the lower the urbanization rate is, and the higher the urban-rural inequality is. From a dynamic perspective, heavy-industry-oriented development strategy reduces the capital accumulation rate, which results in a slower progress of urbanization and a highly persistent urban-rural inequality. The higher the degree of heavy-industry-oriented development strategy, the slower the progress of urbanization, and the longer the urban-rural inequality will last. This mechanism can potentially explain the lower urbanization rate and higher urban-rural inequality in China under a unified framework.     

Urban–rural income polarization and economic growth in China: evidence from the analysis of a dynamic panel data model

Using a dynamic panel data model and the system GMM, this article examines the relationship between urban–rural income polarization and economic growth at the provincial level in the period 1995 to 2010 in China. The estimated results and significant tests indicate that a certain degree of urban–rural income polarization is beneficial to economic growth at the provincial level in both stages for China as a whole, though the contribution of urban–rural income polarization to economic growth is relatively small. Aggravating urban–rural income polarization has a negative impact on economic growth in China. Based on a cluster analysis of regional economic growth at the provincial level, the authors carried out the same analysis separately for two categories of regions too. The results for those two categories of regions show that positive correlations also exist between urban–rural income polarization and economic growth in both stages, which are very similar to the analysis for the whole of China. In addition, a meaningful finding can be derived that the contribution of consumption growth rate to economic growth rate in the second stage is smaller than that in the first stage obviously.     

Unconventional monetary policy and the dollar–euro exchange rate: first results from time-series analysis

This article examines the impact on the US dollar–euro (USD–EUR) exchange rate of the unconventional monetary policy conducted by the US Federal Reserve (Fed) and the European Central Bank (ECB). To that end, we make use of time-series analysis to obtain a reasonable long-run and short run representation of the data generation process and use dummy variables to study how announcements about monetary policy changes can affect the USD–EUR exchange rate. Our results indicate that the announcement and subsequent implementation of such measures by the ECB would have caused an appreciation of the dollar, while those by the Fed would have caused a depreciation of the dollar.     

Are valuation effects desirable from a global perspective?

Recent studies have emphasized the role of valuation effects due to exchange rate movements in easing the process of adjustment of the external balance of a country. This paper asks to what extent valuation effects are desirable from a global perspective as a mean to achieve an efficient allocation of resources. In a frictionless world, it is desirable to have large movements in prices and exchange rates. But once a small degree of price rigidity is introduced not only should prices be stabilized but also the response of the exchange rate should be muted. There is a minor role for valuation effects that depends both on the size and composition of assets and liabilities.     

The tax–spending nexus: evidence from Romania using wavelet analysis

This article investigates the relationship between government revenue and expenditure in Romania between 1991 and 2015 using the wavelet approach. The article presents detailed information for different sub-periods and frequencies, emphasising the lead–lag nexus between variables under cyclical and anti-cyclical shocks. The main findings show that using individual taxation techniques under structural reforms should control short-term budget deficits. Separately, when an economic crisis arises, expenditure adjustment is a more appropriate fiscal instrument. In the medium and long term, the taxation system for individuals is recommended to be used to control for budgetary deficits during crisis. At the same time, in the medium term, government expenditures also represent a suitable policy choice.     

Internationalisation,growth and pay inequality: a cointegration analysis for Turkey, 1970–2007

The nature of the internationalisation-growth-inequality nexus is very complex; and therefore, not surprisingly, there is no consensus on whether increasing openness to trade leads to higher inequality or not – in fact, there is even no full understanding on the impact of the openness on the economic growth. In the case of Turkey it is observed that there is relatively little empirical work that addresses the issue of inequality. Considering this fact, the study aims to provide some more evidence on the complex relationship between trade openness, foreign direct investment, economic growth and pay inequality by utilising a combination of different Theil Indices of pay inequality. The paper utilises the Johansen Cointegration and Granger Causality methods. Our findings yield that higher economic growth resulting from trade openness comes with higher pay inequality.     

The “sugar rush” from innovation subsidies: a robust political economy perspective

The governments of most advanced countries offer some type of financial subsidy to encourage firm innovation and productivity. This paper analyzes the effects of innovation subsidies using a unique Swedish database that contains firm level data for the period 1997–2011, specifically informa tion on firm subsidies over a broad range of programs. Applying causal treatment effect analysis based on matching and a diff-in-diff approach combined with a qualitative case study of Swedish innovation subsidy programs, we test whether such subsidies have positive effects on firm performance. Our results indicate a lack of positive performance effects in the long run for the majority of firms, albeit there are positive short-run effects on human capital investments and also positive short-term productivity effects for the smallest firms. These findings are interpreted from a robust political economy perspective that reveals that the problems of acquiring correct information and designing appropriate incentives are so complex that the absence of significant positive long-run effects on firm performance for the majority of firms is not surprising.     

Innovation as a nonlinear process,the scientometric perspective,and the specification of an ‘innovation opportunities explorer’

The process of innovation follows nonlinear patterns across the domains of science, technology, and the economy. Novel bibliometric mapping techniques can be used to investigate and represent distinctive, but complementary perspectives on the innovation process (e.g. ‘demand’ and ‘supply’) as well as the interactions among these perspectives using animations. In a map, the different perspectives can be represented as ‘continents’ of data related to varying extents over time. For example, the different branches of Medical Subject Headings (MeSH) in the Medline database provide sources of such perspectives (e.g. ‘Diseases’ vs ‘Drugs and Chemicals’). The multiple-perspective approach enables us to reconstruct facets of the dynamics of innovation, in terms of selection mechanisms shaping localisable trajectories and/or resulting in more globalised regimes. By expanding the data with patents and scholarly publications, we demonstrate the use of this multi-perspective approach in the case of RNA Interference (RNAi). The possibility to develop an ‘Innovation Opportunities Explorer’ is specified.     

Innovation and imitation: substitutes or complements?

Most of the research on imitation and innovation has focused on developed countries and examined whether imitation promotes or hinders innovation at the macro, industry and intra firm level, and the effect that this has on economic growth. Less research has been conducted about the dynamics that exist between innovation and imitation at the plant-level in developing countries, and the effect that trade policy has on this relationship. This article uses plant-level data from Mexico to analyse the dynamic relationship that exists between innovation and imitation at the microeconomic level. The empirical results suggest that in the context of a developing country, innovation and imitation complement each other and trade policy has no effect on this relationship.     

Big data analysis adaptation and enterprises’ competitive advantages: the perspective of dynamic capability and resource-based theories

Big data analysis (BDA) adaptation has been spreading unprecedentedly fast among Chinese enterprises to gain a competitive advantage. Based on the resource-based theory (RBT) and dynamic capability theory (DCT), this study aims to propose a conceptual model to identify the sources of competitive advantages, interrelationship of their components, and the mechanism of obtaining competitive advantage. The results reveal several important findings. 1) Different dimensions of dynamic capabilities all have effects on competitive advantage, but they have different paths to influence these. 2) Two dimensions of dynamic capabilities have direct effects on the competitive advantages, and strategy flexibility has indirect effects on these. 3) Three dimensions of resources all indirectly and positively influence competitive advantages by affecting dynamic capabilities. 4) The path of resources and dynamic capabilities affecting competitive advantage are identified. The findings have important implications for managers that leverage BDA to achieve comparative advantages in business.
