Capital Flows, Vertical Multinationals, Wage Inequality, and Welfare

Wage inequality between skilled and unskilled labor in the US and its trading partners, Mexico and Chile, has increased since 1980, while Taiwan's wage inequality has decreased since the mid‐1980s. The authors provide a new explanation for the latter, involving a rise in capital flows from Taiwan to less‐developed countries (LDCs) in the form of vertical multinationals (MNEs), and a corresponding rise in intermediate‐good exports from the MNEs to subsidiaries in LDCs. Moreover, national income in both countries definitely improves.     

Income inequality and export prices across countries

This paper provides theory and evidence on the links between income inequality within a destination country and the patterns of trade and export prices. The theoretical framework relates income inequality to product quality and prices using a simple demand composition effect. The model predicts that a more unequal income distribution in a destination country leads to higher average prices, though the effect is nonlinear and disappears for rich enough countries. The predictions are tested using detailed firm‐level data. Controlling for income per capita, prices are systematically higher in more unequal destinations, and the strength of this effect depends on income per capita. Results are particularly important for middle‐income countries and hold only for differentiated goods, and in particular for products with a high degree of vertical differentiation.     

On factor proportions as a guide to the future composition of developing country exports

A previously widely quoted study by Hal Lary (Imports of Manufactures from: Less Developed Countries) concluded that labour intensity should, under the postulates of the factor-proportions model, be useful for anticipating the future composition of LDC exports. In this paper, we empirically evaluate the utility of labour intensity as such a guide. As a first test recent changes in developing countries' market shares for Lary's labour intensive products are compared with those for other items. With few exceptions, the export performance for labour intensive goods was superior. Overall, the LDCs increased their market share for these products in spite of a generally declining competitive position in world trade. Separate (correlation) tests indicate that a direct relation exists between the degree of labour intensity of individual products and changes in developing countries' market shares. That is, the LDCs made the greatest gains in the most labour intensive products.Since labour intensity was shown to provide a guide to changes in developing country exports, we examined its implications for the future. Specifically, the National Bureau's indices of value added per employee were updated to gain insights into the probable composition of LDC trade in the 1980s. The results suggest that many of the products previously identified as being labour intensive, and therefore suitable for production and export by developing countries, would also be classified as likely LDC export items on the basis of 1976 production data. In fact, textiles, footwear, and furniture became relatively more labour intensive which suggests that the LDCs will put increased competitive pressure on developed country producers of these products over the next decade. However, our statistics also show that some miscellaneous manufactures and processed foods became more capital intensive. This indicates that LDCs may be losing their competitive edge in these products and are less likely to make sizeable market share gains in the future.     

Foreign exchange reserves and import demand in a developing economy: the case of Pakistan

Conventional specifications of import demand in LDCs have commonly been plagued by implausible and unstable parameter estimates. This paper shows the importance of imposing long‐run income homogeneity and of including foreign exchange reserves when estimating import demand function for an LDC. Using several cointegration techniques, it is shown that there is one linear relationship among real imports, real income, relative import prices and real foreign exchange reserves. In addition, by employing stability tests for cointegrated systems by Hansen (1992a), the paper shows that only when foreign exchange reserves and long‐run unit‐income homogeneity are accounted for does a constant parameter, long‐run equilibrium relation emerge for Pakistan. Also, the ensuing short‐run dynamic model is constant and data‐coherent. Finally, the study provides information on the speed of adjustment to equilibrium and the median and mean time lags of adjustments of real imports to changes in their determinants. The results indicate a quick response of real imports to changes in their determinants.     

Providing Duty-Free Access to Australian Markets for Least-Developed Countries: A General Equilibrium Analysis

The Doha ministerial declaration commits WTO members to liberalising access to their markets for least‐developed countries (LDCs). Preferential trade policies have diverse impacts on the initiating country and its trading partners. These effects are of concern to scholars and policy makers. We use Australia as a case study to quantify the direct and indirect effects of providing preferential access to LDC imports entering Australian markets, using a general equilibrium model of the world economy. LDCs are projected to benefit and Australia is predicted to lose, reflecting adverse terms of trade effects. However, the magnitude of the adverse effect on Australia is small. If one was to view this initiative as an exercise in foreign aid, it suggests that Australia can provide a significant benefit to the poorest nations with which it trades, at almost no cost to itself.

Trade,income and the Baltic Dry Index

Does trade improve the income levels of the poor and less developed nations? Focusing on the Least Developed Countries (LDCs) designated by the United Nations, we construct a new measure of trade cost, based on the Baltic Dry Index (BDI), as an instrument for trade. The BDI reflects the cost of utilizing dry bulk carriers, which are specially designed vessels for transporting primary goods internationally, where these goods dominate the output and export sectors of the LDCs. We find that a 1% expansion in trade raises GDP per capita by approximately 0.5% on average. This estimate is much larger than previously found in the literature and its quantitative significance emphasizes the importance of trade towards the economic development of low income countries.     

Import prices,income, and inequality

We compare three theoretical explanations for the positive empirical relationship between importer income per capita and traded goods prices. A first explanation is that consumers with higher incomes demand higher quality goods with higher prices. A second explanation is that wealthier people exhibit an increased willingness to pay for necessary goods as more goods enter the consumption set in a hierarchic demand system, and can thus be charged higher markups. A third explanation is that consumers with higher incomes are more finicky regarding their preferred variety in an ideal variety framework and can thus be charged higher markups. We discriminate between these three theories by focusing on the effect of income inequality on trade prices. Based on a large dataset with bilateral HS6 level data on 1260 final goods categories from more than 100 countries between 2000 and 2004, we find a highly significant negative effect of income inequality on unit values. This contradicts both the demand for quality and finickyness theories, while providing support for the increased willingness to pay theory linked to hierarchic demand. These findings on income inequality do not falsify the quality expansion model and the ideal variety model per se. However, the results do argue for place of importance of hierarchic demand.     

Neighborhood effects of developing country protection

We examine how protection in LDCs affects welfare in other countries whose economic circumstances are similar. Theoretical analysis suggests the effects may be positive or negative. Analysis of data on protection in nine selected LDCs showed positive correlations among patterns of protection and trade, but a tendency for greater protection against the exports of other LDCs than against developed countries. To evaluate the general equilibrium economic effects involved, we used the Michigan Computational Model of World Production and Trade. The results showed positive terms-of-trade effects on other countries within the LDC sample group and negative effects for may DCs. However, the terms-of-trade improvement was very small and cannot be expected to outweigh the efficiency losses of protection within the LDCs themselves.     

Local Content Requirement under Vertical Technology Diffusion

Many developing countries (LDCs) still impose a local content requirement (LCR) regulation on multinational enterprises (multinationals). The authors develop a simple model to investigate whether the introduction of an LCR affects a multinational's choice of technology transfer. The key assumption made in their analysis is that the multinational in an LDC prefers importing intermediate inputs from its home country, for the manufacture of final goods, to purchasing them from local suppliers equipped with outdated technology. However, the LCR of the LDC forces the multinational to purchase a fixed proportion of its intermediate inputs. The authors show that the magnitude of an LCR policy cannot affect the multinational's decision regarding technology transfer under technology diffusion. In addition, an increase in the LCR may foreclose technology diffusion because it could make the multinational establish its own intermediate input supplier(s) and become a vertically integrated multinational.     

Managerial capital,occupational choice and inequality in a global economy

This study proposes a simple theory of trade with endogenous firm productivity, occupational choice and income inequality. Individuals with different managerial talent choose to become entrepreneurs or workers. Entrepreneurs enhance firm productivity by investing in managerial capital. The model generates three income classes: low‐income workers facing the prospect of unemployment, middle‐income entrepreneurs managing domestic firms and high‐income entrepreneurs managing global firms. Trade liberalization policies raise unemployment and improve welfare. A reduction in per‐unit trade costs raises top incomes and generates labour‐market polarization. A reduction in fixed exporting costs has an ambiguous effect on top incomes and personal income distribution. Policies reducing labour‐market frictions or the costs of managerial‐capital acquisition create more jobs and improve welfare. The income distributional effects of labour‐market policies depend on which policy is implemented.     

Redistributive innovation policy,inequality, and efficiency

We examine the efficiency and distributional effects of regressive and progressive public R&D policies that target high‐tech and low‐tech sectors using a heterogenous‐agent growth model with in‐house R&D and incomplete capital markets. We find that such policies have important implications for efficiency and inequality. A regressive public R&D investment financed by income tax could boost growth and welfare via a positive effect on individual savings and effort. It could, however, also lower growth and welfare via its effect on the efficiency–inequality trade‐off. Thus, the relationship between public R&D spending and welfare is hump‐shaped, admitting an optimal degree of regressivity in public R&D spending. Using our baseline model, and the US state‐level GDP data, we derive the degree of regressiveness of public R&D investment in US states. We find that US states are more regressive in their R&D investment than the optimal regressiveness implied by our growth model.     

Dumping,antidumping duties,and price undertakings

This paper examines which types of firms, from a developed country (DC) or a less developed country (LDC), tend to practice dumping, using a two-market equilibrium analysis of trade in similar products. Specifically, we present a vertical product differentiation model of duopolistic competition between a DC firm and an LDC firm under free trade to show that the DC firm sells a higher-quality product without dumping. In contrast, the LDC firm sells a lower-quality product and practices dumping in the DC market by charging a price lower than the product's price in the LDC's local market. In response to the LDC dumping, the DC government's use of an optimal antidumping duty increases its domestic welfare. The LDC's social welfare may increase if its exporting firm accepts price undertaking rather than dumping. From the perspective of world welfare, defined by aggregating the welfare of the trading countries (DC and LDC), the trade damage measure through imposing antidumping fines on LDC dumping is Pareto-improving compared to free trade (under which dumping takes place) and price undertakings.     

Foreign direct investment,growth and income inequality in less developed countries

How does foreign direct investment (FDI) affect economic growth in less developed countries (LDCs)? What is its association with changes in the income distribution? This paper empirically examines these issues within a cross section of less developed countries between 1970 and 1989. FDI is positively associated with economic growth within this sample of countries. However, there is no strong association between FDI and changes in income inequality within these same countries and over this same time period. Hence, there is no evidence that FDI is increasing income inequality within this group of LDCs.     

Income Level and Income Inequality in the Euro‐Mediterranean Region,C. 14–700

Was the Euro‐Mediterranean region at the time of the Roman Empire and its Western successor states more unequal than the European Union today? We use some scant evidence on personal income distribution within the Empire and differences in average regional incomes to conclude that the Empire was more homogeneous, in terms of regional incomes, than today's EU, and inter‐personal inequality was low. Moreover, income inequality was likely less around year 700 than in Augustus's time. The latter finding contrasts with a view of rising inequality as the Western Roman Empire dissolved.     

Diversification and Specialization Paradox in Developing Country Trade

This paper examines and resolves a puzzling issue associated with less developed country (LDC) export compositions. Since the newly industrialized country (NIC) takeoff during the early 1970s, LDC exports have involved an increasingly broader and diversified export base. Yet trade theories, both “old” that focus on classic comparative advantage, and “new” which rely on scale economies, lead to expectations of growing specialization as a concomitant of LDC takeoff. This study examines periods of rapid growth and structural transformation of trade for a representative group of LDCs covering a wide geographic and temporal sample.     

Saving, Investment, and Capital Mobility in LDCs

The Coakley, Kulasi, and Smith current-account solvency model ( Economic Journal , 1996, pp. 620–7) is used to investigate saving and investment in LDCs. This model implies that saving and investment cointegrate with a unit coefficient irrespective of the degree of capital mobility. Panel and conventional unit-root tests indicate that LDC current accounts are stationary. The Feldstein–Horioka cross-section regression coefficient for LDCs is lower than the corresponding OECD coefficient, indicating different policy responses in these countries rather than higher capital mobility. Finally, adjustment toward solvency is slower in LDCs, reflecting their vulnerability to external shocks and the impact of financial repression.     

How Does Fiscal Consolidation Impact on Income Inequality?

In this paper, we assess the impact of fiscal consolidation on income inequality. Using a panel of 18 industrialized countries from 1978 to 2009, we find that income inequality significantly rises during periods of fiscal consolidation. In addition, while fiscal policy that is driven by spending cuts seems to be detrimental for income distribution, tax hikes seem to have an equalizing effect. We also show that the size of the fiscal consolidation program (in percentage of GDP) has an impact on income inequality. In particular, when consolidation plans represent a small share of GDP, the income gap widens, suggesting that the burden associated with the effort affects disproportionately households at the bottom of the income distribution. Considering the linkages between banking crises and fiscal consolidation, we find that the effect on the income gap is amplified when fiscal adjustments take place after the resolution of such financial turmoil. Similarly, fiscal consolidation programs combined with inflation are likely to increase inequality and the effects of fiscal adjustments on inequality are amplified during periods of relatively low growth. Our results also provide support for a non‐linear relationship between inequality and income and corroborate the idea that trade can promote a more equal distribution of income.     

Trade,growth and income redistribution: A case study of India

The concern of this exercise is with the effectiveness of trade policies and their assessment in achieving economic growth and income equality. A link between growth and equality is provided through employment. If there is substantial increase in employment, the inequality of income distribution is likely to be reduced. Thus, trade by bringing about higher levels of production and employment may reduce income inequality. We have applied a closed input-output model to the Indian data to estimate the interrelationships between trade, growth and income redistribution. It has been found that employment opportunities could be raised substantially through redistribution as well as through export promotion in developing countries such as India, if capital and foreign exchange constraints are not binding. Import substitution, however, does not turn out to be as effective a strategy to achieve these goals.     

Resource-based industrialization in the developing countries: A survey

This survey at

shed light on the potential contribution of industrialization based on resource processing to efficient growth, employment creation, greater equity and economic independence. The use of capital-intensive methods to reduce raw material costs appears to confer comparative advantage on countries with cheap capital. Lower transport costs due to substantial weight reduction in processing may counter this advantage for some stages of processing, but does not universally favor LDC exporters. Most major producers export sufficient quantities to achieve scale economies typical of resource processing, but economies of scale are a barrier in processing for the domestic market in all except the largest LDCs. External economies of industrialization are also thought to favor processing in the industrial countries, but potential linkages could stimulate some complementary investments in LDCs. Because resource-based industries are not impressive contributors to direct or indirect employment creation, they are likely to perpetuate the pattern of dualism and inequality present in typical resource-rich countries.Third-world exporters may be barred from entry into resource processing by the dominance of multinational firms in the metals and petroleum industries; by shipping conference freight rates that discriminate against processed commodities; and by importing country tariff structures that provide substantial effective protection against many LDC semi-processed exports. Processing of natural resources for export tends to continue the broad pattern of trade, financial and technical dependence of developing countries, although market dependence may decrease at some stage of processing. Home-oriented processing avoids market dependence, but cannot escape outside dependency on technology, management and finance.
