Spatial concentration and plant-level productivity in France

This paper analyzes empirically the effect of spatial agglomeration of activities on plant-level productivity, using French firm and plant-level data from 1996 to 2004. We exploit short-run variations of variables by making use of GMM estimation. This allows us to control for endogeneity biases that the estimation of agglomeration economies typically encounters. This means that our paper focuses on a subset of agglomeration economies, the short-run ones. Our results show that French plants benefit from localization economies, but we find very little - if any - evidence of urbanization economies. We also show that those localization benefits are relatively well internalized by firms in their location choice: we find very little difference between the geography that would maximize productivity gains in the short-run and the geography actually observed.

Productivity effects on Mexican manufacturing employment

We examine the effects of labor productivity and total factor productivity (TFP) on employment across 25 Mexican manufacturing industries from 1984 to 2000. Employing panel data methods, several interesting findings emerge. First, we observe a strong and positive impact of NAFTA on employment. Second, productivity exerts a procyclical, positive effect on employment but this effect becomes smaller after NAFTA. Third, partitions of our sample according to capital-labor intensity suggest that industries which are less capital-intensive were affected negatively on impact by NAFTA but that productivity impacted employment positively after NAFTA. In contrast, more capital-intensive industries display these results in reverse.     

Market Imperfection and Productivity Growth—Alternative Estimates for Taiwan

This study first explores why the shares of factor inputs have not been measured correctly and concludes that the earlier findings are biased due to the miscalculation of factor shares which have produced low estimated total factor productivity (TFP) growth in the East Asian countries. Second, three approaches are proposed to empirically illustrate the impact of capital and labor shares on the estimates of TFP growth. It is suggested that TFP growth in the East Asian economies will be understated if net indirect taxes and imperfect competition profit are ignored. Finally, by taking the net indirect taxes and imperfect competition profits into account, the result of this paper indicates that Taiwan's economy has enjoyed an average annual TFP growth rate of 3.6% over the period 1980–1999.     

Technology catching-up and regulation in European regions

This paper analyses the effects of the intensity of regulations in the product and labour markets on the growth of total factor productivity (TFP) for 121 European regions. A technological catch-up model is estimated for the period 1995–2007. We use the spatial lag of X (SLX) model to capture possible spatial interactions across spatial units. Our empirical findings show that lower levels of regulation are associated with higher TFP growth. Lower barriers to entrepreneurship and lower bureaucratic costs have a positive effect on productivity growth. Corruption raises operational costs, distorts the allocation of resources and negatively affects innovation activities, thereby reducing TFP growth. Further liberalization in the labour market (in terms of hiring and firing regulation, working hours regulation and employment protection legislation) has a significant positive effect on the growth of TFP. In addition, both regional technological and regional human capital have a positive impact on the TFP growth in European regional economies.

Total Factor Productivity Growth and Urbanization Economies: A Case of Indian Industries

Based on panel data for fifteen major states in India, this paper provides evidence in favor of the existence of urbanization economies. In eleven of seventeen two-digit industry groups, total factor productivity growth is responsive to urban population or industrial spread. Although the impact of these variables taken to capture agglomeration economies on total factor productivity growth is not monotonic, economic policy would yield a sub-optimal outcome by ignoring the positive effect of the size factor. Urban population or industrial spread benefits firms by possibly improving the quality of labor and enhancing the productive utilization of resources.     

FOREIGN DIRECT INVESTMENT AND REGIONAL PRODUCTIVITY SPILLOVERS IN US MANUFACTURING

This research examines how inward foreign direct investment (FDI) impacts manufacturing productivity in select industries across US regions. Although some evidence has documented the phenomenon of knowledge spillovers to national economies, little is known about how the regional penetration of foreign investment affects the productivity performance of local firms. The analysis proceeds in a novel fashion by adjusting aggregate data on industry operating statistics to "net out" the contaminating influence of foreign firms producing in each of the host regional economies. A cross section of state-by-industry observations is used to estimate labor productivity, controlling for FDI penetration both by region and by industry. In general, the results demonstrate that domestic firms do not reap productivity gains as a result of a larger presence of foreign affiliates. Related research efforts, although not specifically concerned with the regional transmission of FDI spillovers, offer corroborative support for these findings.     

Spillovers from universities: Evidence from the land-grant program

This paper estimates the short- and long-run effects of universities on geographic clustering of economic activity, labor market composition and local productivity and presents evidence of local spillovers from universities. I treat the designation of land-grant universities in the 1860s as a natural experiment after controlling for the confounding factors with a combination of synthetic control methods and event-study analyses. Three key results are obtained. First, the designation increased local population density by 6 percent within 10 years and 45 percent in 80 years. Second, the designation did not change the relative size of local manufacturing sector. Third, the designation enhanced local manufacturing output per worker by $2136 (1840 dollars; 57 percent) in 80 years while the short-run effects were negligible. This positive effect on the productivity in non-education sectors suggests the existence of local spillovers from universities. Over an 80-year horizon, my results indicate that the increase in manufacturing productivity reflects both the impact of direct spillovers from universities and general agglomeration economies that arise from the increase in population.     

Information technology and U.S. productivity growth: evidence from a prototype industry production account

The rapid productivity growth in the US during the Information Age, prior to the dot-com bust in 2000, and the large contribution of the IT producing sector, is well known. Less known are the sources of the surprisingly rapid TFP growth during the slow growth period after 2000. We construct an account of US economic growth by aggregating over detailed industries using a new data set based on the NAICS classification. We find that, post 2000, TFP originating from the IT-Producing sector decelerated relative to the IT boom, but still accounted for 40% of aggregate productivity growth. This deceleration was counterbalanced by the contribution from IT-Using sectors, which buoyed aggregate TFP growth to almost the same rate as the 1995–2000 period. For aggregate GDP, the contributions to the growth rate of 2.8% during 2000–2007 were: capital input (1.7% points), labor input (0.4) and TFP (0.7).     

AGGLOMERATION ECONOMIES IN JAPAN: TECHNICAL EFFICIENCY, GROWTH AND UNEMPLOYMENT

This paper examines if the effects of agglomeration economies are manifested in technical efficiency and generate faster economic growth and higher (lower) levels of employment (unemployment). Using the prefecture level data for each of the two-digit groups of industries in Japan, it estimates a region-specific technical efficiency index based on the stochastic frontier production function framework. The factor analysis shows that in most of the industry-groups, efficiency has a positive association with external scale variable(s). Though the relationship is not very strong, it would be erroneous to ignore the effect of agglomeration economies on efficiency. For some light goods industries, the agglomeration effect is relatively stronger. Economic growth varies positively with external scale variable(s) and the unemployment rate tends to fall with respect to growth and concentration. This suggests that measures against industrial concentration may be counter-productive, particularly in the context of globalization when countries greatly need to raise productivity.     

Agglomeration economies in urban manufacturing industries: A case of Japanese cities

The effects of urban agglomeration economies on productivities in two-digit manufacturing industries is estimated using the cross section data of Japanese cities in 1979. Urbanization and localization economies, which are major forms of urban agglomeration economies, are explicitly separated. The estimates of these economies vary considerably among industries. Light industries receive more productive advantages from urbanization economies than from localization economies, but heavy industries experience these economies more from localization economies than from urbanization economies.

Structural change accounting with labor market distortions

This paper quantifies the relative importance of sectoral productivity and labor market distortions for structural change in the U.S., India, Mexico and Brazil between 1960 and 2005. I use census data to compute human capital by sector and infer labor market distortions as sectoral gaps in wage per unit of human capital. I incorporate these distortions into a model of structural change, and calibrate the model to reproduce the time paths of sectoral shares of labor and value added for each country. Counterfactuals reveal that (1) TFP growth in agriculture drives most of the decline in its share of labor; (2) the role of labor market distortions is limited.     

LOCATION OF HIGH TECHNOLOGY INDUSTRIES AND REGIONAL DEVELOPMENT – THE ISRAELI CASE

This paper reviews and empirically examines the effectiveness of the Israeli government's declared policy to induce the location of high technology industries in developing regions. The first section of the paper reviews the literature on high technology industry location. The second section presents the findings from the analyses of a sample of 53 high technology Israeli firms in regard to their critical locational determinants. The findings corroborate the results reported in other similar studies. High technology industries, primarily those engaged in research and development, appear to favor the large urban concentrations, where agglomeration economies, large pools of skilled workers and high quality educational and cultural facilities exist. High technology firms which choose to locate in peripheral regions engage primarily in production activities and employ larger proportions of unskilled and semi-skilled labor. The average size of these firms is greater than their counterparts, firms located in and around urban concentrations.     

Agglomeration economies and university program creation in the knowledge economy

Existing academic literature on the relationship between agglomeration economies and university activities is both under-theorized and relatively sparse in terms of empirical examination. This paper addresses each of these voids by contributing and analyzing a market model of pro-revenue education program creation such as graduate-level executive business education (e.g. EMBA) that reveals some intriguing characteristics. For instance, it shows that demand for these pro-revenue programs is inelastic and therefore uniquely determines their availability. More specifically, we show that through agglomeration economies these types of education programs are more likely to emanate from universities located in metropolitan areas and from less academically prestigious universities. Regression analysis of a cross-section of national public universities lends support to important facets of our formal model by suggesting that agglomeration economies continue to increase the probability of offering EMBA programs through a city size of approximately 2.12 million and that the probability that a given business school will offer an EMBA is negatively related to the academic prestige of the institution to which it is affiliated.     

An indirect test of efficient city sizes

This paper develops a model which demonstrates necessary conditions for efficient distribution of labor across areas given the presence of agglomeration economies and congestion externalities. An indirect empirical test for efficient allocation is formulated based on a comparison of estimated agglomeration economies with the compensating variation in occupation-specific wages needed to attract workers to larger cities. The results of this test suggest that there are specific city size ranges where necessary conditions for efficient allocation of resources are not met, particularly for cities in the 1.5 to 2.5 million population range. Current claims that continued growth of the largest U. S. cities is inefficient are not confirmed by the empirical results.     

R&D,Interindustry and International Technology Spillovers and the Total Factor Productivity Growth of Manufacturing Industries in Canada, 1974-1989

The paper presents new econometric evidence on the relationship between total factor productivity growth and the R&D expenditures of Canadian manufacturing industries in the presence of interindustry and international spillovers of technology. In contrast to studies that presume that international spillovers are incorporated in imports of intermediate and/or capital equipment goods, the present paper assumes that the principal channel of transmission of new technology is foreign direct investment. Three original proxies for international spillovers use information on patenting, the size and the origin of foreign ownership in the host country and the R&D expenditures in the country of origin. The results suggest that the nexus between industry's own R&D expenditures and the TFP growth is significant and positive, especially for the process-related R&D. Domestic interindustry spillovers of new technology have a larger effect on TFP than industry's own R&D expenditures. All three proxies for international technology spillovers are associated positively and significantly with TFP growth. However, international spillovers contribute to TFP growth less than domestic interindustry spillovers and less than own process-related R&D.     

Firm relocation and site selection in suburban municipalities

This paper develops a model of the site choice decision of relocating firms in seven single-digit SIC industries. Hypotheses are tested using data on firms which have moved from Milwaukee City to its suburbs between 1964 and 1974. The industries considered are: construction; manufacturing; transportation, communications, and public utilities; wholesale trade; retail trade; finance, insurance and real estate; and services. While this problem has been examined for manufacturing with limited success, the results here are encouraging. The results show that agglomeration economies and an available labor force are important influences in the site choice among suburban locations for firms in all industries. Fiscal variables are at best only of secondary significance in the choice among suburban municipalities.     

Agglomeration elasticities and firm heterogeneity

This paper examines three key issues encountered when estimating the relationship between agglomeration and multi factor productivity (‘agglomeration elasticities’): the sorting of heterogeneous firms, the convexity of agglomeration effects, and the challenges of identifying the impact of persistent spatial differences in effective density. We use a firm-level panel containing production data together with detailed information on the geographic location of employment, covering a high proportion of the New Zealand economy. We are able to control for heterogeneity along firm, region, and industry dimensions, and to estimate separate agglomeration elasticities across industries and regions. Sorting leads to upward biased elasticity estimates but using firm fixed effects can lead to downward bias due to the highly persistent nature of agglomeration variables. Our preferred estimates control for sorting across regions and industries. Overall, we find a positive agglomeration elasticity of 0.066. Within industries and, to a lesser extent within regions, there is pronounced variation in the strength of agglomeration effects, and evidence of decreasing returns to agglomeration. High density areas attract firms that benefit most from agglomeration.
