The Italian Automotive Industry and Economies of Scale

This article investigates scale economies in the Italian automobile industry as well as substitution possibilities between inputs and direct and cross-price elasticities of factor demand, utilizing a cost function with capital, labor, domestic, and imported intermediate goods inputs. Continuing European integration makes economies of scale an important issue. The study results are consistent with economies of scale in the Italian motor vehicle industry, a particularly interesting finding because the Italian automotive industry consists primarily of one firm, Fiat. The estimated direct price elasticities suggest that capital is most responsive to own price changes, and estimated cross elasticities imply that all inputs are substitutes. (JEL D 2, L 6, O 1)     

A Cost Function Analysis of the Australian Transportation Equipment Industry

This article investigates the existence of economies of scale and input cross and direct price elasticities of demand in the Australian motor vehicle industry. Our estimated cost elasticities were less than one (consistent with economies of scale), but not significantly less than one at the 10 per cent level for two versions of the model. However, the estimated cost elasticity was significantly less than one at approximately the 2.5 per cent level for a third. Thus, these results give some credibility to the infant industry argument for continued assistance to the Australian transportation equipment industry. A four-input model separating domestic and foreign intermediate goods inputs suggests that while restrictions on imported components may have given some short-run relief to the domestic components industry and increased the demand for labour domestically, they decreased the demand for domestic capital. Although the infant industry argument could support short-run protectionist policies for the industry, it appears that such policies regarding the Australian motor vehicle industry must be designed carefully with a specified phase-out period if long-term adverse results are to be avoided.     

The Spanish automotive industry: scale economies and input relationships

This paper investigates the existence of economies of scale in the Spanish automobile industry as well as the substitution possibilities between input pairs and the direct and cross price elasticities of demand for the various inputs by estimating a translog cost function for both a three input model involving capital, labour, and intermediate goods as well as a four input model where energy is separated from other intermediate goods. The results of this study are consistent with the hypothesis of economies of scale in the Spanish automobile industry, particularly at the low and mean levels of output. These results also are consistent with the hypothesis that capital is a substitute for the other inputs, but that labour and intermediate goods are complements. Labour and energy also appear to have a complementary relationship over most of the data points in this study. The significance of a complementary relationship between labour and intermediate goods is that any attempt by the Spanish government to restrict imports of these inputs, resulting in higher domestic prices for them, may aggravate an already serious domestic unemployment problem.     

Scale properties and input substitution in mexican electrical equipment manufacturing

This paper investigates the existence of scale economies in the Mexican electrical equipment industry and estimates direct and cross price input demand elasticities using a translog cost function. Although the estimated value of the cost elasticity was consistent with economies of scale, it was significantly less than 1 only at a significance level slightly greater than 5 percent. The estimated cross price elasticities indicated that all of the inputs were substitutes. Nevertheless, while lower trade barriers under the North American Free Trade Agreement, ceteris paribus, may have a short-term adverse effect on the demand for labor in this industry by increasing imports of cheaper capital and intermediate goods, the relatively low values for E_LK and E_LM also support the conclusion that the impact on employment may be relatively small.This project was supported by the Faculty Development Leave Program at the University of Texas at San Antonio.     

A cost-based analysis of scale economies in the French auto industry

This paper examines cost relationships in the French automobile industry using a translog cost function with domestic capital and labor and domestic and foreign intermediate goods inputs. The findings suggest scale economies at lower output levels, but diseconomies at mean and maximum output levels. Cross price elasticity estimates implied all input pairs except capital and foreign parts and labor and domestic parts are substitutes. Except for foreign components, direct price elasticity estimates were inelastic. Thus, further integration of Europe and reduction of foreign input prices may substantially increase their quantity demanded and decrease the demand for domestic labor and parts.     

Insourcing,Outsourcing, and Unemployment in the Spanish Auto Industry

This paper examines the role of outsourced intermediate goods, together with capital, labor, and insourced intermediate products, as inputs in Spain's motor vehicle production. Its findings are consistent with statistically significant economies of scale. Capital and labor are found to be substitutes, as are most of the other input pairs. However, capital and outsourced intermediate goods and labor and insourced intermediate goods appear to have complementary relationships, and the latter relationship has become stronger over the period of study. Any actions that decrease the price of one of the inputs in a complementary pair will increase the demand for the other input. Since labor and outsourced intermediate goods appear to be substitutes, a decrease in import prices as a result of further European integration will decrease the demand for domestic labor and exacerbate Spain's unemployment problem. A similar result holds for insourced and outsourced intermediate goods.     

European Integration and Production in the French Economy

Effects of greater European integration on the French economy are explored with an aggregate cost function. Input direct price elasticities are inelastic, but greatest (absolute value) for capital and lowest for imports. Cross-price elasticities suggest inputs are substitutes and are higher for domestic inputs than domestic input and imports pairs. As trade restrictions fall, effects on domestic input demand may increase as substitution elasticities rise. Inverse output supply price elasticities indicate domestic input prices are relatively important factors affecting consumption goods prices and import prices more important for investment goods. Thus, import price decreases may stimulate investment and growth. (JEL F14 , O10 , O12 )     

The changing structure of cost and demand for the U.S. telecommunications industry

This paper formulates a multiproduct structural model to examine the evolution of the structures of production and demand and their dynamic interaction, over an extended period, 1935–1987, in the U.S. telecommunications industry. We estimate the degree of scale economies, cost elasticities, input price elasticities and the determinants of demand for outputs and for various factors of production. The contributions of the quasi-fixed inputs, such as R&D and physical capital, in the evolution of this industry are evaluated. A number of important issues like the changing characteristics of demand for and cost of local and toll services and the variation of price–cost margin over time are examined under different economic conditions, market structures and regulatory environments. We also analyze the effects of the 1984 divestiture of the Bell System on the cost structure, employment and capital formation of the U.S. telecommunications industry.     

A ray of hope? Another look at the Italian textile industry

Despite increasing competition from newly industrializing countries, Italy’s textile industry has continued to be an important contributor to the domestic economy. Many observers attribute this resilience to the industry’s focus on quality. Here, we take note of that view but also examine production and cost relationships to explore the existence of returns to scale and the interrelationships among inputs to gain additional insights about the future prospects for this industry. The findings are consistent with constant returns to scale and a substitute relationship between all input pairs except for domestic capital and foreign intermediate goods. The results also suggest some increasing flexibility in the labor market, perhaps including informal sector arrangements, greater responsiveness of labor demand to the price of capital, and more international production sharing arrangements. An increasing elasticity over time of the demands for domestic capital and domestic intermediate goods with respect to the price of foreign substitutes was also observed. Since further economies of scale do not exist, maintaining the Italian textile industry’s reputation for outstanding quality will likely be an important survival strategy for some products. For others, production sharing may be necessary to maintain international competitiveness.     

Trade liberalization and the Mexican steel industry

The impact of the North American Free Trade Agreement (NAFTA) on the competitive positions of Mexican and U.S. steel producers is investigated employing a translog cost function with four inputs (capital, labor, domestic intermediate goods, and foreign intermediate goods) to examine scale characteristics and input substitution in Mexican steel production. Results are consistent with diseconomies of scale at high levels of output and with substitute relationships between all input pairs except labor and domestic intermediate goods. Thus, output growth will likely result in cost reductions for Mexican producers only if the industry reaps significant benefits from substitution of foreign inputs for domestic. Recent increases in Mexico's imports of finished steel have much exceeded those of steel industry inputs, and it therefore does not seem likely that a Mexican cost advantage over steel producers in the United States will soon emerge as a result of economies of scale.     

Challenges in the Portuguese textile and clothing industry: a fight for survival

The Portuguese textile and clothing industry thrived after 1960, when Portugal joined the European Free Trade Association, and it has been an important industry in Portugal in terms of value added, employment, and exports. Nevertheless, the industry has experienced significant challenges with the final integration of the apparel and textile industry into GATT on 1 January 2005, as well as the admission of relatively low-wage Bulgaria and Romania into the European Union in 2007. This paper describes recent trends in the industry between 1995 and 2016, including a substantial decrease in output after 2005 and recovery in recent years. In addition, a translog cost function is used to examine the existence of economies of scale, the relationships among inputs, and the effects of the 2005 GATT entry on the industry’s costs. The findings include strong evidence of economies of scale, consistent with the many small and mid-sized enterprises in the Portuguese textile and clothing industry. The results are also consistent with capital and labour being complementary inputs, while other input pairs are substitutes. The entry into GATT may have had a negative impact on cost, though the evidence for that effect is weak.     

CHALLENGES FOR FRANCE IN THE EMERGING INTERNATIONAL ENVIRONMENT: A DYNAMIC ANALYSIS

France faces substantial challenges as the economic integration of Europe and the international economy continues. This article uses a dynamic aggregate translog cost function with inputs of capital, labor, and imports to examine the likely impact of closer world economic ties on France. This technique allows one to estimate short- as well as long-run direct price elasticities of demand for the inputs and cross-price elasticities for each respective input pair. The findings of the article include that (1) the French economy is becoming more sensitive to changes in import prices and (2) all the inputs are substitutes for one another. These results suggest that continuing international economic integration will present substantial challenges to the French economy. The short-run estimates of direct and cross-price elasticities are consistent with the Le Châtelier principle, except for the cross-price elasticities between capital and labor. Some possible reasons for the latter result are discussed in the article. (JEL F14, O10, O12)     

Globalization challenges for the Mexican textile industry

The Doha round and full integration of the textile industry into the GATT have the potential to dramatically affect the Mexican textile industry. This study investigates the nature of scale economies and input relationships for that industry using a cost function with capital, labor, domestic intermediate goods, and imported intermediate goods as inputs. The findings suggest that significant economies of scale exist, and that most inputs are substitutes, although for some years some inputs are complements. Increased domestic input sensitivity to the price of foreign inputs may present challenges for the industry as it struggles to be internationally competitive.     

A cost function analysis of import demand and growth in South Africa

This study investigates the substitutability relationships among capital, labor, and imported inputs for South Africa, utilizing the estimates obtained from an aggregate cost function. Our results are consistent with the hypothesis that capital is a substitute for both domestic labor and imports, but that labor and imports are complementary inputs. This latter result suggests that relaxing South African trade restrictions may have a positive impact, in both the long and the short run, on the demand for domestic labor. Other results suggest that the reduction of market impediments may also positively impact the production of investment goods and economic growth.     

Cost relationships and challenges in the Spanish apparel industry

In the twenty-first century, the Spanish textile and apparel industries have faced substantial challenges, resulting in declining sales and employment. This study concentrates on the apparel industry, since its economic challenges and opportunities differ from those of the textile industry. The analysis employs a transcendental logarithmic cost function to investigate the presence of scale economies and the interrelationships among inputs of domestic capital, labour and intermediate goods as well as outsourced intermediate products for the Spanish apparel industry and discusses the implications for its future competitiveness and the demand for domestic inputs. The results are consistent with diseconomies of scale or, in the case of one model, possibly constant returns to scale, indicating that some contraction of the industry due to international competition will not raise unit costs. All of the inputs except for capital and intermediate goods were found to be substitutes. An important finding is that the cross elasticity values of both labour and domestic intermediate goods with respect to the price of outsourced goods have risen over time, indicating an increased sensitivity of the quantity demanded of these home-country inputs to the price of imported intermediate goods. It follows that domestic input markets will be more substantially affected by international prices for outsourced inputs as the industry tries to maintain its competitiveness in the global environment.     

FIRM SIZE AND EFFICIENCY IN THE SOUTH AFRICAN MOTOR VEHICLE INDUSTRY*

The South African motor vehicle industry has historically been considered a critical industry in the South African economy and the target of numerous government policies designed to protect it and/or increase its international competitiveness. This study examines the cost performance of firms in this industry according to their size, using data categorised by output level. The results are consistent with statistically significant economies of scale at the lowest output levels and a cost inefficiency averaging from about seven to nine per cent for all firms. The findings also suggest that all else equal, the smallest firms and the largest firms have lower unit costs than mid‐sized firms. While this work suggests that policies that would give incentives for the smallest firms to increase their scale of operations might help to reduce their unit costs, further investigation needs to be done with respect to why firms in the mid‐level size categories appear to be less efficient.     

The motor vehicle industry in an emerging nation: the case of Brazil

As in other emerging nations, in Brazil, the motor vehicle industry is considered to be strategically important for economic development because of its backward and forward linkages and possibilities for export-led growth. This study analyses prospects for the industry by estimating an industry-level cost function that includes output of both vehicles and component parts with capital, labour and intermediate goods as inputs. The cost elasticity of output (an indicator of scale properties) and the elasticity relationships among inputs are explored. One unexpected outcome of the work that appears to be robust is that during early years of the study period, the industry had constant returns or even diseconomies of scale. However, during later years, when output was greater, there were economies of scale. This finding is likely the result of some combination of the entry of new firms, the development of new models or technological change. The study concludes that if firm output can be increased, economies of scale can be expected to strengthen the position of the Brazilian industry in the international marketplace.     

The Spanish Textile Industry Sans ATC Quota Protection

The Spanish textile and apparel manufacturing sectors have been badly impacted by the global recession as well as the removal of quotas that were in place with the Agreement on Textiles and Clothing (ATC). This study employs a cost function to investigate the presence of scale economies and the interrelationships among inputs of domestic capital, labor, and intermediate goods as well as outsourced (imported) intermediate products for the Spanish textile industry in a global environment that has become increasingly competitive. While there is evidence of scale economies at low output levels, there is also some evidence consistent with diseconomies of scale at the highest output levels. All of the inputs appear to be substitutes for one another except for domestic capital and outsourced intermediate goods. An important finding is that the demands for both labor and domestic intermediate goods have become increasingly sensitive to the prices of outsourced inputs. The estimated coefficients of dummy variables indicate that reduced international trade restrictions have put downward pressure on unit cost for the industry in recent years. These results suggest that the Spanish textile industry and its domestic suppliers will be increasingly challenged by international competitive pressures.     

The structure of production in South Korea's manufacturing sector

This paper estimates a model of producer behavior for South Korean manufacturing that simultaneously identifies substitution elasticities and scale economies. A non-homothetic translog function is employed which takes on various other functional forms (i.e., Cobb–Douglas, Homothetic, Homogeneous) as special or limiting cases. Four significant conclusions are: (a) there is potential scale economies in each subsector of South Korean manufacturing, (b) the substitutabilities between factor inputs are relatively low, (c) factor demands are price elastic, (d) the scale economies are correlated with the factor intensity.     

RETURNS TO SCALE IN RETAIL TRADE*

This paper attempts to estimate genuine scale effects in retail trade from a cross section of retail stores in Israel. This is done by estimating a simple production function for several retail branches and employing the faithful old direct Cobb-Douglas structure with value added as output and labor and capital inputs. And indeed despite the well-known peculiarities of the retail industry, a cross section estimation produces “normal” production-function estimates with reasonable input elasticities. The estimates also identify marked increasing returns-to-scale parameters, higher in food and lower in branches less affected by consumer participation and geographical dispersion. These increasing returns may explain a good part of the increase in sales per unit of inputs observed in time series.
