International trade and capital accumulation in an overlapping generations model with a public intermediate good

We investigate the effects of a public intermediate good on trade patterns, capital accumulation, and the gains from trade in a two‐country, three‐sector overlapping generations model. A public intermediate good affects not only the productivity of private production but capital accumulation; thus, the results differ from those obtained in previous studies. First, opening to trade may accelerate capital accumulation in the higher‐savings country. Additionally, the country producing a public intermediate good more (which is labor‐intensive) may be the importer of the investment good (which is the most capital‐intensive). Finally, the lower‐savings country may have lower steady‐state welfare under trade.     

Moving beyond the iceberg model: The role of trade relations in endogenizing transportation costs in computable general equilibrium models

Modeling trade and transportation costs is an essential part of multiregional or spatial computable general equilibrium models where interregional trade plays an important rolein shaping economic activity. The majority of such models use the iceberg trade cost approach where part of the produced output (representing the material costs of transportation) is assumed to melt away during transportation. There are a few models which employ a more refined approach with an explicit transportation sector providing transportation services which are then used to ship goods between locations. In this paper we show that this approach, although much more convenient than the iceberg approach, still lacks full usability due to the fact that markets, hence prices are defined at the regional level and as a result, transportation costs can not be endogenous at the trade relation level. Moreover, under regional level market clearing the iceberg and the more detailed approach are equivalent. We propose to refine the definition of market equilibrium and move it to the trade relation level. Using this approach we can gain full advantage of the explicit transport sector in the model with respect to trade cost evolution. We show through simulations that refining the way trade costs are modelled indeed gains new insights, and that moving the market definition to the trade relational level leads to qualitative changes in the effect of labor supply shocks on main model variables. The paper also presents a method to estimate a SAM by reallocating data from standard industries to a transportation sector which is then consistent with the model setup. This SAM can be used to calibrate the refined model with a detailed transportation sector.     

Factor Heterogeneity,Factor Market Imperfection and Trade

This paper develops a tractable model of examining how factor heterogeneity and imperfect factor market interact for determining a pattern of trade. Institution plays a crucial role for the interaction. In my work, firm productivity is defined as a composition of factor productivity and technology. Thus, input selection should affect the pattern of Melitz’s intra-industry allocation due to the incurring transaction cost. For a simple model, I assume two factors (labor and capital) and two sectors, which are relatively less institution-dependent and relatively more institution-dependent. When the economy is open, effect of the transaction cost on income distribution is more drastic for an institutionally underdeveloped country. Depending on institutional quality, the economic openness reallocates resource across countries through job creation or job destruction. The job turnovers redistribute income between heterogeneous labors within countries. The income redistribution is catalyzed by international mobility of capital. As a result, income disparity is widened between the institutionally developed country and the institutionally underdeveloped country. This paper can contribute to the literature of institution and international trade.

On the development strategy of countries of intermediate size—An analysis of heterogeneous firms in a multi-region framework

This paper compares two policies: trade cost reduction and firm relocation cost reduction using a three-country version of a heterogeneous-firms geography and trade model, where the three countries have different market (population) sizes. We show how the effects of the two policies differ, in particular for the country of intermediate size. Unless the intermediate country is very small, in a relative sense, it will gain industry when relocation costs are reduced, but lose industry when trade costs are reduced. The smallest country loses industry in both cases, but only experiences lower welfare in the case of lower relocation costs. Thus, the ranking of the policies from the point of view of the two small and intermediate countries tends to be the opposite.     

Gains From Trade for Nonmaterialists,Environmentalists, and the Overworked

The author proposes an alternative to the traditional definition of the gains from international trade and, hence, an alternative defense of free trade. Rather than showing that free trade allows a country to consume more of all final goods, the author's approach shows that free trade allows a country to consume the same basket of final goods that it would consume in autarchy but at a reduced cost measured in terms of foregone productive resources. Thus, free trade gives a country the option to maintain the same material standard of living that it would have enjoyed in autarchy while enjoying more leisure and using fewer natural resources in production.     

Openness to trade as a determinant of the macroeconomic elasticity of substitution

Several theoretical and empirical studies on economic growth consider the macroeconomic elasticity of substitution between capital and labor as a measure of economic flexibility that depends on technological as well as institutional aspects. One institutional aspect of economic flexibility is openness to trade. I examine in a Heckscher–Ohlin model with two large countries trading intermediate goods how openness affects the elasticity of substitution. If the technology has a constant elasticity of substitution in a closed economy, opening up to trade raises the elasticity of substitution only in the country that accumulates capital at a faster rate.     

Quality-enhancing trade liberalization

This paper examines the effect of trade liberalization on the quality of industrial goods produced by a developing country. The intermediate goods used as inputs to industrial production are assumed to be non-traded and produced by firms with market power. It is shown here that for a certain range of human capital levels, exposure to free trade, instead of resulting in de-industrialization, can raise welfare through an improvement in the quality of domestically produced industrial goods.     

To integrate with a high- or low-wage country: That is the question

This paper considers the question of whether a country with the intermediate capital–labor ratio is better off forming a free trade area with the higher or lower wage country. Typical analyses of gains from trade ignore the effects of free trade on factor prices. When Europe forms a free trade area with a high-wage economy, the equalized wage rises and rent declines, while the price of the importable declines. Workers unambiguously benefit, but integration has an ambiguous effect on capitalists. However, consumers as a whole benefit from the integration and workers can more than offset the losses of the capitalists. On the other hand, Europe's integration with a low-wage economy raises rent but lowers the wage and the price of the labor-intensive good. Accordingly, capitalists unambiguously benefit, but integration has an ambiguous effect on workers. Again, welfare of all consumers rises and the capitalists can more than offset the losses of workers.     

Beyond Icebergs: Towards a Theory of Biased Globalization

In contrast to domestic trade, international trade inherently requires more intensive use of skilled labour with expertise in areas such as international business, language skills, and maritime insurance, and the transoceanic transportation is more capital intensive than the local transportation. In the presence of such bias in factor demands, globalization caused by an improvement in the export technologies can lead to a worldwide increase in the relative prices of the factors used intensively in international trade. Furthermore, a worldwide increase in the factors used intensively in international trade can lead to globalization. To capture these effects, we develop a flexible approach to model costly international trade, which includes the standard iceberg approach as a special case. More specifically, we extend the Ricardian model of trade with a continuum of goods by introducing multiple factors of production and by making technologies of supplying goods depend on whether the destination is home or abroad. If the technologies of supplying the same good to the two destinations differ only in total factor productivity, the model becomes isomorphic to the Ricardian model with the iceberg cost. By allowing the two technologies to differ in the factor intensities, our approach enables us to examine the links between factor endowments, factor prices, and globalization that cannot be captured by the iceberg approach.     

International Trade with a Public Intermediate Good and the Gains from Trade*

This paper presents a one‐primary factor, two‐consumer good, and two‐country model of international trade where each country’s government supplies a country‐specific public intermediate good so as to attain efficient production. By introducing the Marshallian adjustment process, it is demonstrated that the country with larger factor endowment exports the good whose productivity is more sensitive to the public intermediate good. Our normative analysis of free trade shows the following results. First, at least one country gains from trade. Secondly, if a country incompletely specializes in the trading equilibrium, the country necessarily loses from trade.     

Variable labour supply, specialisation-based external economies, and capital inflow

This paper examines the impact of exogenous capital inflow on prices, production, labour supply, and welfare in the presence of specialisation-based externalities. The paper utilises a simple model of an economy that produces one-final good by means of capital, labour, and a large number of varieties of an intermediate good. The intermediate good is produced by means of capital and labour. The supply of capital is exogenous but the supply of labour is endogenous. The presence of internal economies of scale in the intermediate good industry gives rise to specialisation-based external economies in the production of the final good. Perfect competition prevails in the final good industry whereas the intermediate good industry operates under Chamberlinian monopolistic competition. It is shown that exogenous capital inflow decreases labour supply and increases welfare only if the elasticity of substitution between leisure and the final good is equal to or less than unity. The paper also shows that, if trade opens up between two otherwise similar economies, a capital rich country would be a net importer of varieties of the intermediate good.     

The effects of labour unions on international capital tax competition

Abstract We analyze the impact of labour market rigidities on tax competition between two imperfectly integrated countries. Following a shift from a competitive to a unionized labour market in both countries, the capital tax can be adjusted upward in the country with the less rigid labour market, whereas the capital tax is always adjusted downward in the other country. Moreover, by reducing the labour cost differential between countries, trade liberalization gives rise to tax and welfare convergences. Finally, when a country adopts a flexible labour market, the unionized country may attract the majority of capital.     

Neoclassical Growth, Manufacturing Agglomeration, and Terms of Trade

This study reverses the prediction of geography and growth models that trade integration may cause income divergence. Moreover, a new dynamic welfare gain of trade openness is identified. These results are obtained from embedding a new economic geography model into a neoclassical growth model. Starting from symmetric countries, a country that accumulates more capital than the other increases its home market size, improves its terms of trade, and lowers its relative consumption price index, because trade costs drive a wedge in between relative producer and consumption price indices. Both effects in turn tend to increase its marginal revenue product of capital relative to the other country (divergence forces), while factor substitution diminishes its marginal revenue product of capital (convergence force). Reducing trade costs decreases the wedge and weakens the divergence forces, while the convergence force is unaffected. Hence, divergence is more likely with higher rather than lower trade costs.     

Explaining Export Performance through Inputs: Evidence from Aggregated Cross‐country Firm‐level Data

Which trade barrier related to intermediate inputs forms a greater burden on the export performance of firms in developing countries? Using aggregated cross‐country firm‐level data covering 43 mostly developing economies, this paper estimates the marginal importance of the impact of various intermediate input trade cost barriers, namely tariffs, non‐tariff barriers (NTBs) and services barriers, on firms' export behavior. In a cross‐sectoral setting, this paper takes the firm's export performance in goods as a central focus to study the effects of these different trade barriers through the exporting firm's choice of use of intermediate inputs. The results show that the most significant trade barriers on inputs that impede export performance in developing countries are mainly NTBs and restrictions of services.     

技术进步方式与贸易条件变化研究

在垄断竞争的差异化产品模型假设下,在成本结构中引入技术进步的两种类型即资本节约型技术进步和劳动节约型技术进步。本国劳动节约型的技术进步使得本国同类产品的产出数量增多,贸易条件下降;但资本节约型的技术进步可使本国差异化产品种类增多,贸易条件上升。通过中国工业品行业的资本劳动比和贸易条件变化的关系,初步验证了该理论模型。

Oligopsonistic Intermediate Input and Patterns of Trade *

We examine the validities of traditional trade theorems and patterns of trade for an economy with an oligopsonistic intermediate input. Specifically, the model consists of two final goods. one intermediate good, and two primary factors. One final good and the intermediate good are produced using primary factors, capital and labor. The second final good is produced using the intermediate good and labor. All markets operate under perfect competition except the intermediate good market, which is oligopsonistic. This model reflects the real world phenomena of oligopsony power excerted by some industries (e.g., the food processing industry) in the intermediate good purchases. Our analysis shows that some of the traditional trade theorems and H.O trade pattern may be overturned if the factor intensity of the competitive sector lies between those of oligopsony and intermediate good sectors.

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.
