Trade and the Transmission of Technology

Abstract: This paper integrates earlier studies on the link of productivity and research and development (R&D) in different industries of a closed economy with the more recent emphasis on R&D-driven growth and international trade in open economies. In this framework, technology in the form of product designs is transmitted to other industries, both domestically as well as internationally, through trade in differentiated intermediate goods. I present empirical results based on a new industry-level data set that covers more than 65 percent of the world’s manufacturing output and most of the world’s R&D expenditures between 1970 and 1991. The analysis considers productivity effects from R&D in the domestic industry itself, from R&D in other domestic industries, as well as in the same and other foreign industries. I estimate strong productivity effects both from own R&D spending and R&D conducted elsewhere. The contribution of R&D in the industry itself is about 50 percent in this sample. Domestic R&D in other industries is the source of 30 percent of the productivity increases, and the remaining 20 percent are due to R&D expenditures in foreign industries.

States and Markets: The Advantage of an Early Start

Abstract: In this paper, an index of the depth of experience with state-level institutions, or state antiquity, is derived for a large set of countries. We show that state antiquity is significantly correlated with measures of political stability and institutional quality, with income per capita, and with the rate of economic growth between 1960 and 1995. State antiquity contributes significantly to the explanation of differences in growth rates, explaining half of the differences in growth rates between countries like China and Mauritania, which are located at the two ends of the spectrum. It is also a good instrument for “social infrastructure,” which explains cross-country differences in worker productivity.

Does the Mortality Decline Promote Economic Growth

Abstract: This paper analyzes qualitatively and quantitatively the effects of declining mortality rates on fertility, education and economic growth. The analysis demonstrates that if individuals are prudent in the face of uncertainty about child survival, a decline in an exogenous mortality rate reduces precautionary demand for children and increases parental investment in each child. Once mortality is endogenized, population growth becomes a hump-shaped function of income per capita. At low levels of income population growth rises as income per capita rises leading to a Malthusian steady-state equilibrium, whereas at high levels of income population growth declines leading to a sustained growth steady-state equilibrium.

How Robust is the Growth-Openness Connection? Historical Evidence

Abstract: Previous literature has established a positive correlation between openness to international trade and GDP per capita growth for developed and developing economies in recent decades. However, looking at historical evidence from 1870 to the present, this paper finds no support for a positive growth-openness connection before 1970. In fact, the correlation is negative for the period 1920–1940. Cross-country growth regressions estimated for the period 1920–1990 suggest that the positive correlation between openness and growth is only a recent phenomenon. The paper provides useful conclusions regarding the robustness not only of the openness variables but also of other growth determinants.

Income Inequality and Economic Growth: Evidence from American Data

Abstract: While most cross-country studies find a negative relationship between income inequality and economic growth, studies that use panel data suggest the presence of a positive relationship between inequality and growth. This paper uses a cross-state panel for the United States to assess the relationship between inequality and growth. Using both standard fixed effects and GMM estimations, this paper does not find evidence of a positive relationship between inequality and growth but finds some evidence in support of a negative relationship between inequality and growth. The paper, however, shows that the relationship between inequality and growth is not robust and that small differences in the method used to measure inequality can result in large differences in the estimated relationship between inequality and growth.

Explaining Growth: A Contest Between Models

Abstract: Recent contributions to the empirical growth literature show no tendency to convergence in specification, as researchers seek to identify new variables that can account for significant regional effects in earlier work. We conduct non-nested tests between the models of Barro (1997), Easterly and Levine (1997) and Sachs and Warner (1997). The data strongly prefer an encompassing model, but fail to reject any of the candidate models, implying that each model represents a partial truth. We identify a model that includes most (but not all) of the regressors in the candidate models and is robust to the inclusion of regional dummies.

General purpose technology and wage inequality

Abstract: The recent changes in the US wage structure are often linked to the new wave of capital-embodied information technologies. The existing literature has emphasized either the accelerated pace or the skill-bias of embodied technical progress as the driving force behind the rise in wage inequality. A key, neglected, aspect is the “general purpose” nature of the new information technologies. This paper formalizes the idea of generality of technology in two ways, one related to human capital (skill transferability) and one to physical capital (vintage compatibility) and studies the impact of an increase in these two dimensions of technological generality on equilibrium wage inequality.

Economic Distance and Cross-Country Spillovers

Abstract: Rates of long-run economic growth are not independent across countries. To account for this dependence we decompose the spatial covariance function of growth rates into a function of each country’s own observable characteristics, its unobservable characteristics, and cross-country spillovers. We use original data on economic distance to structure observed variation in countries’ long term growth rates. We use this structure to estimate the magnitude of economic interdependence among nations, and to give a nonparametric characterization of the relationship between economic distance and the magnitude of cross-country spillovers. These spillovers turn out to be quite important, accounting for more of the spatial covariance in growth rates than unobservable variables, and by some measures rivalling the importance of the country’s own observable characteristics.

Twin Engines of Growth: Skills and Technology as Equal Partners in Balanced Growth

Abstract: We develop an endogenous growth model in which skill acquisition by households and innovation by firms make distinct contributions to productivity growth. Nevertheless, the incentives faced by firms and households are inextricably linked because skills are required to implement new technologies. Skills and technologies are dynamic complements but, because their production complementarity is inherently bounded, they are “equal partners” in driving growth: neither can generate sustained growth alone. Our model has important implications for the effectiveness of alternative growth-promoting policies, for interpretating the empirical relationship between growth and schooling, and the relationship between growth and intergenerational wage dispersion.

The Division of Labor, Inequality and Growth

Abstract: We present a model that links the division of labor and economic growth with the division of wealth in society. When capital market imperfections restrict the access of poor households to capital, the division of wealth affects individual incentives to invest in specialization. In turn, the division of labor determines the dynamics of the wealth distribution. A highly concentrated distribution of wealth leads to a low degree of specialization, low productivity, and low wages. In that case workers are unable to accumulate enough wealth to invest in specialization. Hence, in a highly unequal society, there is a vicious cycle in which the degree of specialization, productivity and wages stay low, wealth and income inequality stays high and the economy stagnates. By contrast, greater equality increases investment in specialization and leads to a greater division of labor and higher long run development.

Development Dynamics: Economic Integration and the Demographic Transition

Abstract: This paper examines the influence of economic integration—widening of the trading area—on economic development and the demographic transition. Economies produce with different technologies depending on their scale. Greater integration between regions (greater extensive scale) is instrumental in changing rates of return, which generates an industrial revolution and provokes changes in child bearing behavior. The demographic transition follows from the mortality response to income and birth response to greater scale. The model is calibrated and simulated using historical data from Europe. Historical evidence is cited to support the idea that integration precedes the dramatic rise in economic growth rates.

Creative Destruction and the Rise of Inequality

Abstract: Common wisdom interprets the rise in inequality of the last two decades as the result of a skill-biased labor demand shift. This explanation does not account for two important observations: (i) within-group inequality has also markedly risen, and (ii) the rise of inequality has been accompanied by a rise of the volatility of earnings. This paper argues that a dual labor market structure, where some workers are paid efficiency-wages can account for the empirical regularities, in the absence of skilled biased technological change. The analysis demonstrates that an unbiased innovation, as well as North–South trade, can contribute to the efficiency wage premium, and thus to wage inequality, by increasing labor turnover.

The Skill Premium, Technological Change and Appropriability

Abstract: This paper demonstrates that an increase in the relative supply of educated workers generates a structural change in the production structure towards a knowledge-intensive production process. This structural shift may ultimately lead to an increase in the return to educated labor despite the increase in their supply. The paper argues that the steady increase in the supply of educated workers that most Western economies have experienced in recent decades may be viewed as the driving force behind the observed pattern of wage inequality. In particular, the paper demonstrates that if firms can appropriate a sufficient share of the intertemporal return from knowledge generating activities of their labor force, a gradual increase in the supply of skilled workers would generate only a temporary reduction in the skill premium followed by a permanent increase in the return to skill.

Pursuing Problems in Growth

Abstract: This paper explores the theoretical implications of Schmookler’s (1966) argument that a key determinant of technological change is the usefulness of new technologies. There is both historical and empirical support for his argument. The analysis implies that on-going growth depends delicately on a tension between uses for solutions to technological problems and the allocation of resources toward pursuing those solutions. Even alongside an endogenously increasing number of problems pursued, increasing research labor need not increase technology growth or per capita income growth. The results provide reconciliation of stylized facts regarding technological change and growth in the United States and Western Europe.
