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.     

Endogenous fluctuations in a cournotian monopolistic competition model with free entry and market power variability

The purpose of this article is to show that there is a link between imperfections of competition and occurrence of endogenous fluctuations. We consider a two-sector model in which a perfectly competitive final good sector uses inputs that are produced in a Cournot monopolistic competition market. We show that when inputs are not perfect substitutes, and the depreciation rate of capital is sufficiently small, Neimark bifurcations are susceptible to emerge. This is a consequence of additional variability in the dynamical system generated by the dependence of the markup on the number of firms. This number changes over time because firms can enter and exit the market without costs. Moreover, a fixed cost in the technology ensures that the number of active firms at a given date is finite provided that the elasticity of substitution between inputs is bounded from above.     

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.     

Job Creation, Job Destruction, and the International Division of Labor

The authors incorporate equilibrium unemployment due to imperfect matching into a model of trade in intermediate inputs. Firms are assumed to be price‐takers and their size is given by technology. Firms enter the market as long as expected profits cover the search cost they incur initially; jobs are endogenously destroyed by random shocks that affect firms’ price–cost margins. Trade increases productivity in the final good and then demand for each intermediate input. Steady‐state unemployment is reduced after trade integration because the rate of job destruction is reduced, which in turn induces an indirect positive effect on job creation. A more volatile environment faced by firms does not necessarily increase unemployment. However, the rate of job destruction unambiguously rises, and rises more under free trade.     

Enhancing Vertical Efficiency Through Horizontal Licensing

This paper examines the role of patent licensing in the age of outsourcing. When firms rely on outsourced inputs, a patent holder’s decision to license has both competitive and supplier pricing effects. By issuing a license, the firm increases competition in the product market. At the same time, the need to make royalty payments “weakens” the firm’s rival, making it more sensitive to supplier pricing. The supplier responds by softening pricing terms, and the firm benefits by siphoning some of these gains via the license fee. Not only can the licensor gain, but all other parties (the licensee, supplier, and consumers) can also benefit. This role of licensing presents additional considerations for regulators shaping patent laws.

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.     

On microfoundations of the city

This paper considers the spatial structure of a city subject to final demand and vertical linkages. Individuals consume differentiated goods (or services) and firms purchase differentiated inputs (or services) in product (or service) markets where firms compete under monopolistic competition. Workers rent their residential lots in an urban land market and contribute to the production of differentiated goods and inputs. We show that firms and workers co-agglomerate and endogenously form a city. We characterize and discuss the spatial distribution of firms and consumers in such cities on one- and two-dimensional spaces. We show that final demand and vertical linkages raise the urban density and reduce the city spread.     

Market Size,Local Sourcing and Policy Competition for Foreign Direct Investment

This paper analyzes policy competition for a foreign‐owned monopolist firm between two asymmetric countries. In particular, one country has a larger economy than the other country. At the same time, the small country produces an intermediate good for the final good production, while the large country does not. We show that whether a country will win foreign direct investment (FDI) competition is determined by the interaction between relative transport costs of intermediate and final goods and the market size of the large country relative to that of the small country; and policy competition for FDI may Pareto weakly improve national welfare of the competing countries.     

Search and the market for ideas

We study a market where innovators, who are good at coming up with ideas, can sell them to entrepreneurs, who might be better at implementing them. The market is decentralized, with random matching and bargaining. Ideas are characterized by five salient features: they are indivisible; partially nonrival; intermediate inputs; subject to informational frictions; and difficult to collateralize. This last feature gives rise to a demand by entrepreneurs for liquidity. We determine which ideas get traded in equilibrium and compare this to the efficient outcome, emphasizing the impact of bargaining and liquidity considerations. Among other applications, we study how outcomes in the idea market affect the labor market.     

An equilibrium model of a second economy market in a centrally planned economy

We study a CPE in which an identical good is sold on the official market (OM) and a “second economy” market (SEM ). Planners set parameters. Managers divide inputs between markets to maximize expected utility of wealth. Consumers are expected utility maximizers who purchase the good on the OM or SEM. On the OM, excess demand exists at the non-Walrasian price; delivery date is stochastic. The SEM offers immediate availability. Our solution concept involves the rational expectations of managers, the consistency of consumers' decisions, and a market-clearing SEM. We solve for SEM price and supply and investigate various comparative statics.     

Transfer Pricing and Ownership Structure

We study the performance of jointly owned production units where upstream firms sell inputs to a downstream final market producer. It is found that, compared to integrated firms, co-ownership leads to overinvoicing of input prices (transfer prices), resulting in lower aggregate profits. Tax and tariff policy may lessen the organizational inefficiencies of jointly owned firms. The analysis suggests that firms must have other reasons for forming jointly owned production units than those guided by production efficiency and benefits from delegation of decision-making.

Cost relationships and globalization in the Australian clothing industry

Australia developed a substantial clothing industry with protectionist international trade policies, including prohibitively high tariffs, quotas, and subsidies. The industry became an important source of jobs, with over 6.5 per cent of total manufacturing employment at the close of the 1960s. As Australia has moved towards freer trade, employment in clothing production has fallen substantially. The question of whether the clothing industry can remain viable in its new environment became an important issue. Here, we examine two crucial economic considerations relating to that question: economies of scale and relations (substitute/complementary) between the various inputs, both domestic and outsourced foreign. The findings strongly indicate the presence of economies of scale and that the industry has reduced its unit costs over the period of study. The results also suggest that most of the inputs are substitutes for one another, although only the estimated cross price elasticities between capital and labour are highly statistically significant in both models utilized in the study. To be successful in the future, the Australian clothing industry will likely need to find market niches where it can offer superior products and/or service as well as further reduce its unit costs.     

Economic integration and agglomeration in a middle product economy

We examine the interactions between economic integration and employment agglomeration in a neoclassical-growth, middle-product economy. There are two vertically integrated economies, with competitive final good firms operating plants in both regions and monopolistically-competitive intermediate good firms operating each in only one region. Immobile workers are employed with traded middle products to produce the nontraded final good; mobile workers are used with immobile capital to design and produce differentiated intermediate good inputs. While agglomeration and growth need not be positively related, trade need not enhance regional growth nor widen the skilled-unskilled wage gap.     

Human capital use,innovation, patent protection,and economic growth in multiple regions

We provide the first theoretical analysis of the effects of human capital use, innovative activity, and patent protection, on economic growth in a model with many regions. In each region, consumers have constant relative risk-aversion preferences, there is no human capital growth, and there are three kinds of manufacturing activities involving the production of blueprints for inputs (machines), the inputs themselves, and a single final consumption good. Our analysis generates four results. For any given region, we first describe the balanced growth path (BGP) equilibrium and show that the BGP growth rate depends negatively on the rate at which patents expire. Second, we characterize the transitional dynamics in our model. Third, we determine the value of the patent expiry rate that maximizes the equilibrium growth rate of a region. Finally, we show that a policy of offering perpetual patent protection does not necessarily maximize social welfare in a region.     

A Simple Two-Sector Model of Outsourcing

Outsourcing has become an increasingly contentious subject ever since N. Gregory Mankiw remarked in 2004 that outsourcing is just another way of doing international trade, and must be beneficial to the nation, including the workers. We construct a simple two-sector specific-factor model and explore the validity of Mankiw's remarks. We find his ideas are valid when the country does not produce any outsourced factor's work at home in that both the laborers and the nation benefit. But when some outsourced factor cum intermediate good is also produced at home, the nation still benefits but the workers may suffer.     

A multi-region model of economic growth with human capital and negative externalities in innovation

We use a multi-region model and provide the first theoretical analysis of the effects of human capital use and a particular kind of innovative activity on economic growth. In each of the N heterogeneous regions in our model, consumers have constant relative risk aversion preferences, there are negative externalities in innovation, and there are three kinds of manufacturing activities involving the production of blueprints for inputs or machines, the inputs or machines themselves, and a single final good for consumption. Our analysis generates four salient findings. First, for each of the N regions, we define a balanced growth path equilibrium, we characterize the market clearing factor prices, and we determine the free entry condition in the R&D sector. Second, we show that without growth in human capital, there is no sustained economic growth in any of the N regions. Third, we show that human capital growth generates sustained economic growth in each of the N regions. Finally, when discussing the above three findings, we shed light on the spatial dimensions of economic growth in our multi-region aggregate economy.     

Incentives for input foreclosure

We analyze the incentives of a vertically integrated firm to foreclose downstream rivals in a model of upstream price competition between suppliers of only imperfectly substitutable inputs. Our main motivation is a critical assessment of common assertions that draw inferences from pre-merger observable variables to post-merger incentives to foreclose. In particular, we find that, contrary to some commonly expressed views, high margins on the downstream and low margins on the upstream market are not good predictors for the incentives of a newly integrated firm to foreclose rivals. Besides this contribution to policy, our model also extends existing results in the literature on vertical foreclosure through allowing for the interaction of product differentiation on the upstream and on the downstream market.     

Oligopsony Distortions and Welfare Implications of Trade*

While imperfect competition in the output market has garnered extensive focus in the new trade theory literature, input market imperfection has received considerably less attention. Since market power in input purchase has been growing in recent years, it is worth examining the welfare implications of trade arising from oligopsony power. We develop a model consisting of two final goods, one intermediate good, and two primary factors (capital and labor). One final good and the intermediate good employ primary factors, whereas the other final good uses labor and the intermediate input. All markets operate under perfect competition except for the intermediate input, which is oligopsonistic. Using this model, we show that oligopsony can lead to some anomalies such as an increase in the oligopsony output, reward to the intensive‐factor in the oligopsony sector, national welfare, and deterioration of terms of trade, but it always decreases the reward to the intermediate input.     

中印承接国际服务外包的比较优势分析

现代服务业是人力资本密集型的行业,但为什么像中国与印度这样的发展中国家却承接了大量的国际服务外包,通过比较服务外包承接国的人力资本禀赋以及分析人力资本与国际服务外包的相关性,发现中国与印度在国际服务外包中的比较优势取决于该国熟练劳动力的绝对数量,而不是熟练劳动力在该国总劳动力数量中的相对比例.这也是印度与中国这样的人口大国能够成为主要服务外包承接国的原因之一.     

Employment,job turnover,and trade in producer services: UK firm‐level evidence

Abstract We provide the first firm‐level evidence of the impact of the trade in producer services (‘offshoring’) on the labour market. Using a new data set from the UK that measures trade in services at the firm level, we find no evidence that importing intermediate services is associated with job losses or greater worker turnover. Using regression to control for observable differences between firms that import service inputs and those that do not, we show that firms that start importing intermediate services experience faster employment growth than equivalent firms that do not. This seems likely to be the result of positive demand shocks, which cause a simultaneous increase in employment, output, and use of imported service inputs.
