Occupational safety and profit maximization: Friends or foes?

The rise of the Industrial Revolution is often depicted as a cause of hazardous working conditions and is skillfully epitomized in William Blake's tale of a child chimney sweeper. Conventional wisdom puts firm profit in conflict with occupational safety. We reexamine this argument noting that injuries are very costly to firms because they lead to higher wage premiums, worker compensation, and costly work stoppages. We hypothesize that it is precisely for these reasons that firms in the industries with dangerous working conditions have the strongest incentives to innovate and substitute more capital for labor. Using a longitudinal panel of U.S. industries, we test and confirm our hypothesis that higher injury rates lead to higher capital stock per worker, over time. Moreover, our estimates suggest that firms provide more capital and equipment per worker than what would have been there based solely on the compensating wage differential.     

HOW IMPORTANT ARE CAPITAL AND TOTAL FACTOR PRODUCTIVITY FOR ECONOMIC GROWTH?

We examine the relative importance of the growth of physical and human capital and the growth of total factor productivity (TFP) using newly organized data on 145 countries that spans more than 100 years for 23 of these countries. For all countries, only 14% of average output growth per worker is associated with TFP growth. We use priors from theories to construct estimates of the relative importance of the variances of aggregate input growth and TFP growth across countries. Much of the importance of the variance of TFP growth across countries is associated with negative TFP growth. (JEL O47 , O50 , O57 , O30 , N10 )     

GROWTH AND CONVERGENCE WHEN TECHNOLOGY AND HUMAN CAPITAL ARE COMPLEMENTS

This article presents a model of endogenous growth, in which a firm's technology and a country's human capital stock are complementary in the production of output. Production technologies are created by costly research and development (R&D) and are owned by firms that can freely choose where in the world to produce. Both production and R&D have a positive effect on a country's human capital stock. While all countries typically grow at the same rate in the long run, they differ in their levels of human capital, per capita output, and the quality of the technologies that are used in production. A country's relative position in terms of productivity is history dependent. Countries that start out with a lower human capital stock or industrialize later end up with a lower per capita GDP in long‐term equilibrium. (JEL O4, O33, O47)     

Diaspora strategies,skilled migrants and human capital enhancement in Jamaica

In an attempt to boost its stock of human capital and access to global flows of investment, knowledge and innovation, the Jamaican state has begun to turn to skilled members of its diaspora as a vital and untapped economic resource. State strategies to accumulate human capital within the diaspora, however, raise questions about the culture of labour markets and their effects on human capital enhancement and the transfer of knowledge. Drawing on the labour market experiences of skilled members of the Jamaican diaspora currently living on the island, I explore the possibilities and limits that skilled diaspora network strategies offer for capturing, transforming and embedding knowledge, innovation and investment capital in Jamaica.     

DO NATURAL DISASTERS PROMOTE LONG‐RUN GROWTH?

In this article, we investigate the long-run relationships among disasters, capital accumulation, total factor productivity, and economic growth. The cross-country empirical analysis demonstrates that higher frequencies of climatic disasters are correlated with higher rates of human capital accumulation, increases in total factor productivity, and economic growth. Though disaster risk reduces the expected rate of return to physical capital, risk also serves to increase the relative return to human capital. Thus, physical capital investment may fall, but there is also a substitution toward human capital investment. Disasters also provide the impetus to update the capital stock and adopt new technologies, leading to improvements in total factor productivity.     

THE DURABILITY OF HUMAN CAPITAL: SOME NEW EVIDENCE

This paper analyzes the effect of chronological aging, experience, job search, change of job and/or employer, and formal training on the wage growth of a sample of young men. Following the human capital literature, wage growth directly corresponds to human capital and the analysis allows for the assessment of the durability or rate of depreciation of human capital if further investments are not made. The findings suggest that human capital is not very durable, contrary to some previous estimates given in the literature.     

Life Expectancy, Schooling Time, Retirement, and Growth

I analyze how changes in life expectancy affect retirement age, education time, and growth rates of economies. I set up a continuous time, overlapping generations model of endogenous growth with externalities in human capital production. I find that increases in life expectancy give rise to first, higher retirement ages and second, higher education spans. A threshold level for life expectancy exists such that per capita growth rates follow an inverted U pattern.     

Effects of positive attitude and optimism on employment: Evidence from the US data

Using samples from the National Longitudinal Survey of Youth (NLSY) and following a bivariate probit approach, the current study estimates the worker's employment probability equations in both cross-sectional and panel data frameworks. The study demonstrates that the employment of the worker, which depends on both the worker's labor market participation decision and the employer's hiring decision, is determined partly by the positive and optimistic attitude of the worker. The effects of these attitude variables on both decisions are even larger than the effects of standard human capital variables. The study further demonstrates that the attitude variables affect employment probabilities of men and women differently because their effects on participation and hiring decisions are different.     

Marginal Welfare Costs of Taxation with Human and Physical Capital

We develop a perfect foresight, overlapping generations model with intragenerational inequality and endogenous human and physical capital investment, and we calculate welfare costs for marginal reforms of taxation and public spending. Welfare costs are uniformly lower than in the equivalent static model where human and physical capital are fixed. Most of the upward bias in static estimates arises from fixed human capital because welfare cost is predominantly tax leakage from lower effective labor supply, but reallocating time between education and labor can leave effective labor supply unchanged. Hence, adjustments in human capital have an important mitigating influence on marginal welfare costs. (JEL D91, H20, H31, H41, J22, J24 )     

A MODEL OF GROWTH AND CONVERGENCE IN THE PRESENCE OF INPUT-ENHANCING FACTORS: AN EMPIRICAL STUDY

We introduce and estimate a growth model involving non-neutral technical change characterized by the presence of input-enhancing factors that vary across countries and serve to offset (and potentially eliminate) diminishing returns to capital. Our empirical results, however, indicate that diminishing returns to capital proves too strong to be overcome by, say, capital-enhancing factors. Consequently, our model predicts a conditional convergence of output per worker across countries, with the speed of convergence being slower than that found in earlier models involving neutral technical change.     

DISCONTINUITY OF OUTPUT CONVERGENCE WITHIN THE UNITED STATES: WHY HAS THE COURSE CHANGED?

Has the progress of output convergence changed within the United States? This article examines the output convergence among U.S. states for the last five decades by making several improvements over the extant literature. By applying a battery of convergence tests designed to capture nonlinear transitional dynamics to real output per worker data (i.e., nominal values deflated by state‐level price), we find that output convergence has not been a feature of the continental United States since the 1970s. Instead, output convergence has proceeded among four subgroups within which constituent states have certain characteristics in common. Our regression analysis suggests that state‐level characteristics related to technology and human capital play a crucial role in accounting for the formation and composition of convergence clubs, in agreement with the recent theoretical models of growth and development (e.g., Aghion et al. 2009; Gennaioli et al. 2013b). The level of technology, proxied by patents, turns out to be a consistently significant determinant even after controlling for endogeneity, suggesting that frictions in the diffusion of technology and human capital may have led to clustering of states with different levels of productivity. Our results therefore cast doubt on the common view that diffusion of knowledge and technology across state borders is frictionless. (JEL O47, O51)     

Stained Steel: ESOPs,Meta‐Power,and the Ironies of Corporate Democracy

This case study examines the situated interactions between management and workers during a proposed sale of stock by a U.S. steel manufacturer. Our focus permits a fine‐grained analysis of how varieties of meta‐power both condition and are contested in situated interactions. In our setting, the workers owned the company through an employee stock ownership plan, thereby confounding the traditional hierarchical relation between management and workers. While the contrast between these forms of social organization framed the boundaries for subsequent social interactions, it also served to animate conflicts between workers and management. We found that though the worker‐owned company proclaimed values of “corporate democracy” and “employee participation,” executive management acted as a relay to transmit the disciplining effects of “market forces.” Accordingly, the latter served as an “invisible proxy” reinforcing traditional hierarchical social relations that problematized worker participation. The ironies of corporate democracy abound when worker‐owners find themselves shadow boxing anonymous capital.     

IS THERE A “DOUBLE BONUS” FROM REDUCING INEQUALITY?

We study the effect of inequality on growth in an overlapping generations (OLG) model where inequality affects growth through accumulation of human capital and endogenous fertility. In contrast to much of the existing literature, we argue that the effect of inequality on growth might be non‐monotonic. Our model suggests that the effect depends on the demographic stage of development: inequality impedes growth in low‐fertility (high human capital) economies, but enhances growth in high‐fertility (low human capital) economies. Our finding casts doubt on a “double bonus” from reducing inequality in developing countries which are typically characterized by high fertility. (JEL O40, J13, O15)     

The economics of the decision to join a union

This article attempts to bring about a synthesis of the theory of human capital and the disparate and largely empirical literature on the impact of unions on an individual worker’s terms and conditions of employment. This is done by modeling the decision of a worker to join a unionized firm or vote for a union in an NLRB election. From this model both the theoretically correct valuation and some empirical estimates of the value of the major wage and nonwage (seniority, discipline and discharge, strikes, dues) impacts of unions are presented. Extensions to risk averse workers, free rider problems, union elections and contract ratification votes are also briefly considered.     

Financial Literacy,Human Capital and Stock Market Participation in Europe

Households’ stock market participation has significant effects on savings and on an economy’s financial development and performance. Yet participation into capital markets is limited and quite heterogonous both among and within several countries. This phenomenon represents an empirical puzzle whose understanding is rather incomplete. In this work, we exploited a combination of datasets for nine European countries and used different econometric specifications that allow to control for endogeneity of financial literacy and human capital, to assess the role of several variables in affecting the probability to participate in the stock market in year 2010. Besides socio-demographic variables, we found that financial literacy has a positive and significant effect on stock market participation, together with the level of human capital and social interaction. Country level differences are explained by such institutional factors as the effectiveness of the education system and by the attractiveness of the stock markets.     

Consumer Behavior in the United States: Implications for Social Security Reform

This article shows theoretically and empirically that an aggregate Euler equation relates the growth rate of per capita consumption to the real interest rate, the ratio of private wealth plus asset income to consumption, and the ratio of social security wealth to consumption. Using the estimated Euler equation, the paper then calculates the steady-state effects of social security reform. Reforms that reduce the ratio of social security wealth to consumption are found to shift the balanced growth paths for the capital stock, output, and consumption upward appreciably.     

Entrepreneurial human capital accumulation and the growth of rural businesses: a four-country survey in mountainous and lagging areas of the European union

The paper presents the processes of entrepreneurial human capital accumulation and its impact on rural business growth. Data are derived from four surveys on rural businesses in mountainous and less favoured areas in Southern Europe. Formal pathways of entrepreneurial human capital accumulation refer to education and training, while informal pathways include the cognitive processes of work and managerial experience acquisition and the non-cognitive processes of being raised within an entrepreneurial family environment and/or being raised in the area within which the business is later set-up. The studies reveal that there is a variety of processes of entrepreneurial human capital and knowledge accumulation that are case study specific. Human capital accumulation processes related to education and training or to work and managerial experience still plays the prime role in predicting successful businesses. Results indicate the need for decentralised, flexible and selective entrepreneurial human capital accumulation support programmes that take into account local idiosyncrasies and needs.     

NATURAL DISASTERS AS CREATIVE DESTRUCTION? EVIDENCE FROM DEVELOPING COUNTRIES

Recent studies found a robust positive correlation between the frequency of natural disasters and the long-run economic growth after conditioning for other determinants. This result is interpreted as evidence that disasters provide opportunities to update the capital stock and adopt new technologies, thus acting as some type of Schumpeterian creative destruction. The results of cross-country and panel data regressions indicate that the degree of catastrophic risk tends to have a negative effect on the volume of knowledge spillovers between industrialized and developing countries. Only countries with relatively high levels of development benefit from capital upgrading through trade after a natural catastrophe . ( JEL O13, O30, F18)     

INFORMAL LABOR MARKETS AND ON‐THE‐JOB TRAINING: EVIDENCE FROM WAGE DATA

This study examines whether informal sector jobs are a source of training for young less‐educated workers. Controlling for worker and job characteristics, it is found that, in the early years of workers' careers in Mexico, wage growth in the informal sector is higher than in the formal sector. This result is consistent with general human capital investment on‐the‐job if the informal labor market is more competitive than the formal labor market due to frictions generated by labor regulations.
