The Effect of Emissions on U.S. State Total Factor Productivity Growth

This paper investigates the effect of sulphur dioxide (SO2) and nitrogen oxide (NOx) emissions on the Total Factor Productivity (TFP) growth among 48 contiguous U.S. states, for the period 1965-2002. The relationship between TFP growth and emissions is examined using nonparametric econometric techniques that allow for the estimation of the elasticity of pollution for each state and each period and to account for possible nonlinearities in the data. The results indicate that both pollutants positively affect TFP growth. Moreover this effect is nonlinear. The average output elasticity for all states is 0.005 for SO2 and 0.04 for NOx emissions.TFP growth, emissions, semiparametric estimation

A Dual Definition for the Factor Content of Trade and its Effect on Factor Rewards in US Manufacturing Sector

In this paper, first we introduce a dual definition of the Factor Content of Trade (FCT) using the concept of the equivalent autarky equilibrium. A FCT vector is calculated by estimating a symmetric normalized quadratic revenue function for the US manufacturing sector for the period 1965 to 1991. The FCT for capital is positive, while the FCT for skilled and unskilled labor are both negative, suggesting that the Leontief Paradox was not present for the period of investigation. Capital is revealed by trade to be relatively more abundant compared to either type of labor, while skilled labor is relatively more abundant than unskilled labor. Then using the quadratic approximation lemma, the growth rate of the factor rewards is related to the growth rate of FCT, the growth rate of endowments and technological change. We find that technological change is the most important determinant in explaining wage inequality between skilled and unskilled workers in US manufacturing between 1967 and 1991.International trade, relative wages, Factor Content of Trade, skilled and unskilled labour, Leontief Paradox, revenue function.

Public Infrastructure, Input Efficiency and Productivity Growth in the Canadian Food Processing Industry

Canadian food processing is an important manufacturing industry, accounting for 13 percent of shipments. By its nature food processing depends on infrastructure capital. Our objective is to estimate infrastructure’s effects on input requirements, cost and productivity. The increase in capital and decrease in materials were respectively 2.5 and 3 times greater than the -0.07 infrastructure elasticity of labor. Infrastructure investment was cost-reducing by inducing reductions in employment and intermediate inputs. A 1 percent increase caused cost to decline by 0.16 percent. Infrastructure capital was a major contributor to productivity, annually contributing 0.5 percentage points. This was nearly double TFP growth.Food Processing, Infrastructure Capital, Productivity Growth.

Infrastructure and Public R&D Investments, and the Growth of Factor Productivity in US Manufacturing Industries

In this paper we examine the effects of publicly financed infrastructure and R&D capital on the cost structure and productivity performance of twelve two-digit U.S. manufacturing industries. A general framework is developed to measure contribution of demand, relative input prices, technical change, as well as publicly financed capital on total factor productivity growth. The magnitude of the contribution of these sources varies considerably across industries: in some changes in demand dominate while in others changes in technology or relative prices are the main contributors. Publicly financed infrastructure and R&D capital contribute to productivity growth. However, the magnitudes of their contribution vary considerably across industries and on the whole they are not the major contributors to TFP in these industries.

Public R&D Policies and Cost Behavior of the US Manufacturing Industries

This paper estimates and evaluates the contributions of R&D tax incentives and publicly financed R&D investment policies in promoting growth of output and privately funded R&D investment in US manufacturing industries. Publicly financed R&D induces cost savings but crowds out privately-financed R&D investment while the incremental R&D tax credit and the immediate deductibility provision of R&D expenditures have a significant impact on privately financed R&D investment. The optimal mix of both instruments is an important element for sustaining a balanced growth in output and productivity in the manufacturing sector.

The Effect of Information Technology and Human Capital on Economic Growth

In this paper we compare the impact of hardware, software and com munication equipments, widely referred to as information and communication technologies (ICT) on economic growth among the advanced industrialized countries. We use nonparametric techniques that allow us to directly estimate the elasticity of ICT and human capital for each country and time period. We also examine whether the nonlinear relationship between human capital and growth, found in the literature, still persists in the presence of ICT e¤ects. The data covers the period from 1980-2004, for a range of OECD countries and the results indicate that there exist a nonlinear relationship between ICT and productivity along with a nonlinear relationship between human capital and productivity. Additionally, we observe that in high levels of ICT capital the output elasticities of human capital are larger and the more educated workers in a country the higher are the output elasticities of ICT.

An Updated Ranking of Academic Journals in Economics

We conduct an update of the ranking of economic journals by Kalaitzidakis, Mamuneas and Stengos (2003). However, our present study differs methodologically from that earlier study in an important dimension. We use a rolling window of years between 2003 and 2008, for each year counting the number of citations of articles published in the previous ten years. This allows us to obtain a smoother longer view of the evolution of rankings in the period under consideration and avoid the inherent randomness that may exist at any particular year. Using this framework we proceed to examine the relative ranking of the Canadian Journal of Economics over time. We find the Canadian Journal managed not only to maintain its relative position, but to also improve it over time.

The Contribution of Pollution to Productivity Growth.

In this paper we examine the effect of pollution, as measured by CO2 emissions, on economic growth among a set of OECD countries during the period 1981-1998. We examine the relationship between total factor productivity (TFP) growth and pollution using a semiparametric smooth coefficient model that allow us to directly estimate the output elasticity of pollution. The results indicate that there exists a nonlinear relationship between pollution and TFP growth. The output elasticity of pollution is small with an average sample value of 0.008. In addition we find an average contribution of pollution to productivity growth of about 1 percent for the period 1981-1998.

Is the Financial Development and Economic Growth Relationship Nonlinear?

Using nonparametric estimation techniques we find that, in contrast to recent research, the finance-growth relationship is linear when the previously documented nonlinearity between initial per capita income, human capital and economic growth is taken into account.
