Earnings Mobility and Long-Run Inequality: An Analysis Using Matched CPS Data

In this article we use matched cross sections from the Current Population Survey (CPS) to examine patterns of short-term earnings mobility for the period 1967-91, which we then employ to assess the impact of rising annual individual earnings inequality on inequality over a longer span, First, we find that less-educated individuals and blacks have more instability in their earnings than those who are more highly educated and non-black. Second, short-term mobility levels have not undergone major changes over the time span we examine. Third, our results suggest that long-run inequality (calculated over five years) rose in the latter half of the 1980s. Fourth, important differences exist across demographic groups in long-run inequality trends, with long-term inequality increasing most in the 1980s for less-educated males.     

Industry characteristics influencing the technical output: A case of small and medium size firms in the US

Using the small and medium size firms in the US as a sample, this paper reports on interrelationship among patents, publications and new products. Correlates of R&D expenditure, patents and papers and new products are presented. Relationships between firm size and R&D output and productivity are also investigated.
Since the study is based on correlational analysis, causal inferences are not drawn. The data indicates that the three indicators are related, but their strength of relationship varies with industries. Growth of sales is related with new products, but not with patents or papers.
Although the data point to the fact that small firms are more productive than their larger counterparts, there are many reasons to come to such a sweeping generalisation. Reporting of R&D data is not reliable for small firms as the very definition of R&D differs from firm to firm. Nature of R&D also changes as the firm grows in size; opportunities for patents or new products also change accordingly. These make it difficult to accurately measure and compare the R&D efficiency across firms of different sizes.     

Unionization,Inequality and Redistribution

This article explores the implications of the OECD‐wide decline of union density for earnings inequality and income redistribution by looking at aggregate (country‐level) data. Over the period 1975–95, countries that experienced relatively large declines in union density also experienced relatively large increases in earnings inequality. In addition, governments apparently became less willing to engage in ‘compensatory redistribution’ in these countries. Since the early 1990s, however, union decline has become less closely associated with rising earnings inequality and redistributive policy changes. I argue that the declining relevance of unionization has to do with changes in the position of union members in the income distribution. In most OECD countries, the average union member has become relatively better off as union density has declined and union members have probably become less supportive of wage solidarity and redistributive government policies.     

What Caused Rising Earnings Inequality in Britain? Evidence from Time Series, 1970–1993

The paper reviews some of the competing explanations for the rising levels of earnings inequality in Britain, such as skill shortages, rising unemployment, globalization, demographic factors and inflation. These explanations are rejected in favour of the idea that it was the major changes in the institutional pay-setting arrangements that were largely responsible for rising inequality. Union density figures and strike data are explored in support of this thesis.     

Labor Inspections in the Developing World: Stylized Facts from the Enterprise Survey

This paper empirically explores the incidence of labor inspections across registered firms in 72 developing countries. Results show that larger firms are more likely to be inspected than smaller firms. Interestingly, inspections are less likely to occur among firms with a larger share of low‐skilled workers, and that operate in industries with more tax evasion. We explore the heterogeneity of these findings across income and geographic groups, and conclude by briefly discussing the consistency of the stylized facts with competing theories of inspection agencies’ behavior.     

R&D investment dynamics in agglomerations under weak appropriability regimes: Evidence from Indian R&D labs

What are the dynamics of R&D investment when firms agglomerate in environments with weak intellectual property rights protection? Specifically, do foreign and domestic firms present equal opportunities for free riding by domestic firms in such environments? We examine the impact on local firms' R&D investment from knowledge spillovers originating from co‐located foreign and domestic firms within and across industries. Building on fieldwork in India, we predict free riding by local firms on nearby foreign and local firms. Furthermore, we expect local firms to free ride more from other local firms within their industry and from foreign firms across industries. Analyzing a sample of 3,475 R&D lab investment decisions during 2003–2010 in India, we find that local firms free ride from other local firms both within and across industries.

Hysteresis and export targeting

A direct and largely untested implication of hysteresis concerns the extent of market entering and leaving in response to large movements in exchange rates. This note examines, for 359 4-digit U.S. SIC industries, data on the distribution of U.S. exports by country of destination (a proxy for the number of markets served) from 1978 to 1987 and relates changes in these distributions to overall exchange rate movements. We seek to explain differences in the response across industries on the basis of differences in sunk costs. The empirical results are generally consistent with the hysteresis approach. While in periods of general dollar depreciation firms spread exports more widely across foreign markets, this effect is seen to be limited in industries with relatively large distribution and media advertising costs, for which much of the costs of establishing export networks may be sunk.     

Does interdependency affect firm and industry profitability? an empirical test

Strategy researchers have argued that heterogeneity in firms' practices and profitability within and across industries may derive from industry‐level differences in the extent of interdependencies among firms' activities. Theoretical models have clarified how and why differences in the extent of the interdependencies faced by firms across industries may affect the distributions of firm profits, but the specific predictions from these models have not been empirically tested. In this paper, we present what we believe is the first large scale empirical analysis linking differences in the extent of interdependencies across industries to differences in the distribution of firm profits within and across those industries. We use survey data to measure interdependencies systematically across a wide number of industries, thus addressing the primary obstacle to incorporating interdependencies in larger scale empirical work, and find evidence consistent with the theoretical predictions: average profitability is highest in industries with moderate levels of interdependency; the dispersion of profits among firms is higher in industries with more extensive interdependencies; and industries with more extensive interdependencies have a more positively skewed performance distribution. We find that the effect of interdependencies on average industry profitability is similar in scale to the effect of patent protection and industry growth rates, placing interdependency squarely among the strategy field's central concepts.

Long‐Term Earnings Inequality,Earnings Instability and Temporary Employment in Spain: 1993–2000

This article provides a longitudinal perspective on changes in Spanish male earnings inequality for the period 1993–2000 by decomposing the earnings covariance structure into its permanent and transitory parts. Cross‐sectional earnings inequality of male full‐time employees falls over the second half of the 1990s. Such decline was determined by a decrease in earnings instability and an increase of the permanent earnings component. Given the marked decline in temporary employment over the sample period, we also examine the effect of the type of contract on earnings variance components and find that workers on a fixed‐term contract face, on average, more instability than workers on a permanent contract. This evidence suggests that the decline in temporary employment is responsible for the decreasing earnings instability.     

The Unequal Effect of India's Industrial Liberalization on Firms’ Decision to Innovate: Do Business Conditions Matter?

Product‐market competition can boost industry growth if firms invest more in innovation. Using a natural policy experiment, the removal of India's License Raj, we show that firms in liberalized industries were 9% more likely to invest in R&D than firms in non‐liberalized industries. However, the impacts were not the same across firms of different size. After the reforms, firms in the top quartile were 23% more likely to invest in R&D than those in the lowest size quartile. Both productivity differences across firms and the heterogeneous impacts of business conditions on firms explain unequal effects of India's industrial liberalization reform.     

Potential foreign competition in US manufacturing

Trade barriers are falling and firms are competing in increasingly open international markets. The data reveal considerable heterogeneity across industries in the intertemporal path of import-shares. Against this backdrop, we focus on an issue that is increasingly important for competition policy analysis: ‘potential’ foreign competition. Inadequate attention to this aspect could result in a biased picture of total competition, leading to misguided antitrust decisions. Drawing on the conceptual framework outlined by Landes and Posner [Harvard Law Review, 94 (1981) 937], we measure potential foreign competition by the intertemporal response of industry import-share to industry-specific and aggregate economic factors, and our estimates indicate wide variation across industries in this dimension. A particularly striking finding is that highly concentrated industries, which are more likely to be subject to antitrust scrutiny, have a greater degree of potential foreign competition than industries with low concentration, even though the extent of actual foreign competition is similar across these groups of industries.     

What Can Explain the Increase in Earnings Inequality Among Males?

Increases in the inequality of earnings among male workers since the late sixties have been attributed primarily to shifts in employment from goods-producing to service-producing activities and the baby-boom cohort's entry into the labor market. This paper provides empirical estimates of the magnitude of these and other potential causes of the increase in earnings inequality from 1967 to 1985. The results show that changes related to the age composition of the labor force and to the industrial composition of the labor force account for only a portion of the increase in inequality. Most of the increase in unexplained by either factor. Other contributing factors include a rise in the return to education, a change in the relationship between age and education among males, and a decline in the marriage rate among younger males.     

Types of firms generating network externalities and MNCs' co‐location decisions

This study identifies and examines sources of network externalities that influence MNCs to agglomerate their foreign operations in specific regions. Using data for Korean firms that invested in China, this study found that network externalities were sensitive to the types of firms constituting a regional network. It also found stronger network externalities within firms than across firms, from firms of the same nationality than from those of different nationalities, and from firms in the same industry than from those of different industries. As we defined the types of firms more precisely, distinctive curvilinear relationships between network externalities and the likelihood of co‐location emerged.

A Note on the Equivalent Risk Class Assumption

The assumption that firms within the same industry are subject to equivalent degrees of basic business uncertainty is widely employed in empirical studies of capital structure effects and underlies many of the approaches to valuation in the security analysis literature.

This paper presents test of this important, but previously untested, assumption. It is shown that, given the validity of a measure of the cyclical variability of a firm's earnings as a proxy uncertainty measure, homogeneity of basic business uncertainty is not achieved by confining samples to single industries. Variation in the proxy measure is as wide within industry groups as among those groups     

Operational flexibility and market valuation of earnings

This paper examines the association between the stock returns and accounting earnings of firms that have different levels of operational flexibility. Operational flexibility is a firm’s ability to respond profitably to environmental fluctuations by shifting factors of production within a multinational network of subsidiaries. The geographic breadth and depth of a firm’s multinational network are used as indicators of operational flexibility. We find a significantly greater coefficient relating stock returns and accounting earnings for multinational firms that operate in many countries, but limit their concentration in any one foreign country, than for other multinational firms or domestic firms. This coefficient is significantly smaller for multinational firms whose foreign subsidiaries are highly concentrated in a few countries. When all multinational firms are pooled together, we find their earnings‐returns association does not differ from that of domestic firms. Copyright © 1999 John Wiley & Sons, Ltd.     

Competing capitalisms: capital investment in American,German, and Japanese firms

This study explains one way the home country institutional environment causes strategy differences across firms from different countries. It contrasts the investment conduct of American, German, and Japanese firms in the 10 largest manufacturing industries. We find profound national differences among these firms that are stable across industries. These differing conducts are tied to the institutional environments of the home market. The shareholder firms of the United States make investments primarily in response to expected investment returns, measured by Tobin’s Q ratio. The coalitional firms of Germany and Japan make investments primarily in response to the availability of internal finance, measured by operating cash flow.

Local IndustryEmployment Share and the Experiences of Displaced Workers

This article examines how industries' share of employment in local labor markets affects displaced workers' reemployment, industry switching, and earnings losses. A key result is that workers displaced from industries with low employment shares are more likely to switch industries after displacement. Earnings loss estimates indicate that for most workers, displacement from an industry that employs a smaller share of the local labor force is associated with larger earnings losses.     

Entry deregulation,firm organization,and wage inequality

This paper identifies a causal link between changes in product market competition, firm reorganization and within-firm wage inequality. We exploit a unique episode of comprehensive firm entry deregulation as a quasi-natural experiment and use exceptionally detailed linked employer-employee data for the universe of private sector firms and workers in Portugal. Following deregulation affected firms flatten their hierarchies: the number of layers is reduced and managers’ span of control increased. Dropping a hierarchy layer is accompanied by a significant reduction in wage inequality within the firm, by 8% for the average pay ratio between the top and the bottom layer and 4.4% for the 90-50 percentile wage ratio, showing that there are real changes arising from firm reorganization. Overall wage dispersion, measured by the standard deviation of hourly pay, is also reduced. We discuss mechanisms and interpretations for these changes.     

The impact of earnings pressure on exploratory innovation

While earnings expectation has been shown to determine a firm’s investment decisions, the knowledge about how such expectation influences a firm’s investment horizon for innovation is still blurred. This study therefore addresses this research issue by examining the relationship between earnings pressure and exploratory innovation while investigating the moderating effects of cross‐rival effect and resource availability. By examining high‐tech industrial firms in S&P 1500 from 2000 to 2012, the results indicate that stock analysts, as information intermediaries between innovation firms and the capital market, impose pressure through earnings forecasts on firms’ exploratory innovation. Our findings also reveal that the earnings pressure‐exploratory innovation relationship can be mitigated when its competitors encounter a higher level of earnings pressure. However, a firm’s financial slack shows less significant association to moderate the earnings pressure‐exploratory innovation relationship. Possible explanations for the results in regard to their theoretical and practical implications are discussed in this study.     

Strategic human capital management in the context of cross‐industry and within‐industry mobility frictions

Research Summary: We develop and test a theory examining how frictions that restrict mobility across industries and frictions constraining mobility within an industry can co‐occur to effectively isolate individual human capital, ultimately changing the firm's make‐versus‐buy decision for human capital. Empirically, we demonstrate that when cross‐industry frictions in the form of limited skill transferability and within‐industry frictions in the form of noncompete enforceability are both present, employees exhibit longer tenures, firms hire workers with less initial experience, firms change the amount and nature of training provided, and wages marginally increase. These findings suggest that sufficiently strong and complementary mobility frictions shift the emphasis of firms’ human capital management practices toward internal development of human capital relative to acquisition on the external market. Managerial Summary : In the face of frictions to employee mobility both within and across industries, which we capture empirically using measures of noncompete enforceability and limited skill transferability across industries, firms tend to hire less experienced workers, such workers exhibit longer tenures, and firms invest more in their training, particularly in the development of new skills. Our findings imply that for firms operating under such complementary frictions, better hiring and internal development capabilities are particularly important for performance, while those firms without such capabilities may benefit from considering ways to circumvent the mobility frictions, including moving out of the focal state or lobbying for different noncompete laws.
