Exports,imports, growth and causality: a study of Slovakia

In this article, we analyse the trade–growth nexus for Slovakia. This country represents a critical case for such research because it is one of the most open economies in the world; by several measures it is the most open economy in the EU, with the most Eurocentric trade, and has maintained one of the best growth performances within the EU over a sustained period of time. In contrast to most contributions to the trade–growth literature, we analyse all six possible causal relationships between Slovakia’s exports, imports and growth, using the technique developed by Toda and Yamamoto (1995), on quarterly data from 1997Q1 to 2014Q4. We find evidence supporting both the export-led-growth hypothesis and the import-led-growth hypothesis. None of the other four relationships was found to be significant.     

Strategic policies and growth: an applied model of R&D-driven endogenous growth

We introduce and explore a general equilibrium model with R&D-driven endogenous growth, whose antecedents are the models of Romer (1990) [Romer, P.M., 1990. Endogenous technological change. Journal of Political Economy, 98, S71-102] and Grossman and Helpman (1991) [Grossman, G.M., Helpman E., 1991. Innovation and Growth in the Global Economy, The MIT Press, Cambridge]. Utilizing evidence from recent econometric studies on sources of growth, the model also accounts explicitly for cross-border technological spillovers. The model is specified and calibrated to data from Japan, and is solved to obtain both the transitional and the steady-state equilibria. We explore the effects of selective trade and R&D promotion policies on long-run growth and social welfare. The model results suggest that while a strategic trade policy has little effect on re-allocating resources into domestic R&D activities, it can significantly affect the cross-border spillovers of technological knowledge, which, in turn, stimulates growth. We find that trade liberalization may cause the growth rate to fall and lead to a loss of social welfare in the long-run, although it improves welfare in the short-run. R&D promotion policies stimulate growth by inducing private agents to allocate more resources to domestic R&D, as well as to take greater advantage of global R&D spillovers. Here, we find significantly high growth effects together with sizable gains in social welfare at low incidence to tax payers.     

Trade liberalization, heterogeneous firms and the soft budget constraint

We analyze the interaction between the soft budget constraint (SBC) and international trade by placing Segal’s (1998) SBC model within Melitz’s (2003) framework of international trade with heterogeneous monopolistically competitive firms. As in Segal’s model, SBC may result in moral hazard. The opening to international trade adds another sort of inefficiency. Some firms that would have become exporters in the absence of SBC choose to apply low effort and not export in order to extract a subsidy from the government. This effect takes place when the trade costs are sufficiently low. Overall, however, trade liberalization reduces inefficiencies generated by SBC. The number of firms subject to moral hazard SBC decreases, aggregate effort level increases and aggregate profits lost due to SBC-induced sub-optimal effort decline as trade costs decrease.     

Global inequality and international trade

The paper analyses the effect of widespread trade liberalisationon global income inequality. The analysis of the trend in globalinequality during 1981–97, presented in the first partof the paper, shows that the apparent growth of income inequalityamong countries conceals a process of convergence. Some developingcountries achieved significantly faster economic growth thanthe advanced industrialised countries and, though small in number,they actually account for a majority of the population of thedeveloping world. Thus international inequality (i.e., the inequalityof distribution of per capita incomes among the world's population)in fact declined even though the inter-country income inequalityincreased. The analysis in the second part of the paper shows(i) that while improved trade performance did have a stimulatingeffect on growth performance of countries, trade liberalisationhad extremely varied effects on trade performance across countries,and (ii) that the distribution of benefits and costs of tradeliberalisation across countries has been such as to reduce internationalinequality without affecting inter-country inequality.     

Parallel Trade and its Ambiguous Effects on Global Welfare

The regulation of parallel trade is a fiercely debated issue in the global trading system. This paper investigates the welfare effects of parallel trade freedom for different levels of trade costs and market size. It is found that parallel trade freedom has a positive effect on global welfare if countries are sufficiently heterogeneous in terms of market size and trade costs are sufficiently low. Contrary to intuition, this result even holds in a situation where parallel trade freedom implies the closure of the smaller market. If, however, countries are virtually homogenous in terms of market size, parallel trade freedom may be detrimental to global welfare for specific levels of trade costs.     

经济政策不确定性与全球贸易低速增长——基于引力模型的分析

不断上升的经济政策不确定性能否有助于解释全球贸易的低速增长呢?文章利用贸易引力模型,从沉没成本、实际需求和预期三种渠道探讨了经济政策不确定性对国际贸易的影响,然后利用国别配对数据对其进行了实证研究.结果表明:(1)贸易规模不但受到进口国经济政策不确定性绝对水平的影响,也受到其相对增速的影响,但出口国经济政策不确定性的影响不显著;(2)经济政策不确定性的贸易抑制效应与进口国的宏观经济状态有关,在失业率较高时期表现更为明显;(3)经济政策不确定性对贸易的影响存在门限特征,不确定性程度较高时期的影响明显高于程度较低时期的影响.文章不但有助于解释2008年金融危机后全球贸易的低速增长,也指出了国际间的政策合作和反对"逆全球化"进而降低经济政策不确定性,是实现全球贸易增长的重要途径.     

Trade,Strategic Environmental Policy,and Global Pollution

This paper examines the effects of international trade in a model with global pollution that accumulates over time because of production emissions in each country. If countries cooperatively determine their environmental policies, autarky and free trade in the absence of trade costs generate the same optimal solution. By contrast, if environmental policies are determined noncooperatively, the effects of trade on global pollution and welfare are ambiguous because policy games can result in multiple equilibria. Although trade increases both the lower and upper bounds of the pollution stock, whether trade expands the range of possible steady‐state pollution levels is ambiguous. The analysis then extends to consider trade costs.     

Regional integration and innovation offshoring with occupational choice and endogenous growth

We study the effects of regional integration on patterns of production and offshoring in a two-region model of occupational choice and endogenous growth. The distribution of asset wealth and allocation of heterogenous workers into innovation and production determines relative market size. When trade costs and knowledge dispersion are high (low), the asset wealthy (poor) region has a larger market and greater shares of innovation and manufacturing. For low to intermediate levels of trade costs, innovation and manufacturing offshoring flows toward the larger region, but when trade costs and knowledge dispersion are high, offshoring flows from the larger asset wealthy region to the smaller asset poor region. Economic growth is unaffected by the shifts in innovation and production that coincide with changes in relative market size.     

Market Integration,Choice of Technology,and Welfare

This paper develops an international trade model where firms in a duopoly may diversify their technologies for strategic reasons. The firms face the same set of technologies given by a tradeoff between marginal costs and fixed costs, but depending on trade costs firms may choose different technologies. Market integration may induce a technological restructuring where firms either diversify their technologies or switch to a homogeneous technology. In general, market integration improves welfare. However, a small decrease of trade costs which induces a switch from heterogeneous technologies to a homogeneous technology may locally reduce global welfare. The model also shows that productivity differences lead to intra‐industry firm heterogeneity in size and exports similar to the “new–new” trade models with monopolistic competition.     

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.     

Costly pollution abatement, competitiveness and plant location decisions

The NAFTA debate included assertions that were used as arguments against trade and investment liberalization. (1) Trade liberalization increases production sensitivity to environmental restrictions (‘environmental dumping’?). (2) Investment liberalization, leading to multinational firms, similarly increases the production and welfare response to costly environmental restrictions. I find that: (1) Trade liberalization increases production sensitivity to costly environmental restrictions, but arguments against liberal trade on welfare grounds do not follow. (2) Multinationals do not increase the production-reallocation effect caused by environmental restrictions or regulations. In addition, I find a great difference between restrictions that fall on fixed costs and restrictions that fall on marginal costs.     

The Costs of U.S. Hegemony: Military power,military spending,and U.S. trade performance

For David Gordon and his collaborators in the social structures of accumulation (SSA) tradition, the willingness to threaten potential adversaries with military forces capable of acting on a global scale was seen to positively affect the U.S. terms of trade. U.S. hegemony yielded specific supply side benefits as favorable terms of trade reduced relative input prices and boosted profitability. Although Gordon and his co-authors recognize the potential costs of sustaining a large, globally active military apparatus, these costs are not incorporated in the econometric models supporting the SSA theory. This paper attempts to extend the SSA analysis by empirically measuring the effects of both military spending and military power on U.S. trade performance over the 1951–1987 period. It is shown that while military power and spending commitments may have positive effects on the terms of trade, these military variables had direct and indirect negative impacts on the U.S. net export balance and therefore domestic aggregate demand. In the context of a model of U.S. growth performance open to international transactions, the overall effect of the postwar military system on U.S. economic growth was likely negative in the cold-war era     

Foreign market entry,upstream market power,and endogenous mode of downstream competition

In a differentiated duopoly model of trade and FDI featuring both horizontal and vertical product differentiation, we examine whether globalization and trade policy measures can generate welfare gains by leading firms to change their mode of competition. We show that when a high-quality foreign variety is manufactured under large frictions due to upstream monopoly power, a foreign firm can become a Bertrand competitor against a Cournot local rival in equilibrium, especially when the relative product quality of the foreign variety is sufficiently high and trade costs are sufficiently low (implying higher input price distortions due to double marginalization). Our results suggest that such strategic asymmetry is welfare improving and that the availability of FDI as an alternative to trade can make welfare-enhancing strategic asymmetry even more likely, especially when both input trade costs and fixed investment costs are sufficiently low and trade costs in final goods are sufficiently large.     

Country Size,Technology and Manufacturing Location

Country size, technology and trade costs jointly affect the location of manufacturing activity. In this paper, the combined effects of country size and technology differences on manufacturing location are examined in a simple new economic geography model. The specification yields a closed‐form, analytic relationship between measures of relative productivity, country size and trade costs. The patterns of agglomeration are consistent with recent empirical evidence. Market and supplier access favor manufacturing agglomeration in large countries for high to intermediate trade costs. High productivity countries, however small, are favored for low trade costs. The model's tractability facilitates welfare analysis.     

Social capital, inclusive networks, and economic performance

Empirical studies show that the relationship between social capital and economic performance is ambiguous. The paper points to the potential trade-off between the sustainability of self-enforcement and the magnitude of gains from trade in social networks as an explanation. Based on an infinitely repeated multi-player prisoners’ dilemma it is shown how self-enforcement of cooperation within a network is influenced by its inclusiveness, its communication capacity, and the complexity of the exchange setting. The paper shows that inclusive social capital can combine both low enforcement costs and high gains from trade even in a complex exchange setting.     

China's Regional Trade and Domestic Market Integrations

The global economic crisis in 2007 forced China to move from export‐led growth to promoting domestic demand. The move is significant, but the success of this new growth strategy depends critically on the level of domestic market integrations. In this paper, we use the methodology proposed by Anderson and Wincoop to examine China's domestic market integrations. We find evidence of border effects at both national and regional levels with significant regional differences, but they are smaller than some earlier studies suggest. Income growth, lower transportation costs, and higher intra‐industry trade all have positive effects on China's regional trade. Among the factors affecting regional trade, a better business environment has the largest positive impact on lifting China's domestic trade between regions, especially in intermediate goods, suggesting that improving business environment should be the priority of government at all levels in China.     

Quality heterogeneity and global economic growth

This paper develops a fully endogenous, variety-expansion growth model with firm-specific quality heterogeneity, limit pricing, and an endogenous distribution of markups. Firms with high-quality products engage in exporting, firms with intermediate-quality products serve the domestic market, and inefficient firms with low-quality products exit the market. Trade liberalization, measured by a reduction in trade costs or a decline in foreign market entry costs, generates a reallocation of resources from low-quality to high-quality products and exit of inefficient firms. However, it has ambiguous effects on the average global quality level, long-run growth, and welfare. An increase in the rate of population growth or in the intensity of trade-related knowledge spillovers accelerates economic growth. The laissez-faire equilibrium is inefficient, and this leaves room for welfare-improving government intervention.     

Trade in intermediate inputs,customs unions,and global free trade

In a three‐country customs union (CU) formation game, I introduce international trade in intermediate inputs and rules of origin (RoO) restrictions. In the case of symmetric countries, I show that as countries become more involved in global supply chains, global free trade is less likely to be a stable equilibrium outcome. RoO can help solve this problem. In the case of asymmetry, depending on the degree of the globalization, free riding (for high degree) or exclusion motive (for low degree) prevents global free trade. Correspondingly, I show that RoO can have helpful or detrimental effects on attaining global free trade.     

Mobile Capital, Local Externalities, and Industrialization

This paper seeks to understand how industrialization is distributed geographically when capital is mobile and labor is not. A stylized model of a spatial economy is constructed where individuals not employed in industry work in traditional activities. Results show that convergence across locations is characterized by a succession of catching-up episodes. As one location at a time industrializes, the others stagnate. This occurs whether or not local externalities are present. These results cast doubt on whether free movements of capital can foster the rapid industrialization of all countries and regions of the world simultaneously.J. Comp. Econom.,December 1997,25(3), pp. 345–365. Stanford University, Stanford, California 94305-6072.     

The trade reducing effects of restrictions on liner shipping

The costs of shipping containerized cargo on liner vessels play a pivotal role in determining a country's integration into international trade. We examine how policy governing the liner shipping sector affects maritime transport costs and seaborne trade flows. Using a novel dataset of services trade policy information, we find that restrictions, particularly on foreign investment, significantly increase maritime transport costs. The cost-inflating effect ranges from 26% to 68%, and the resultant reduction in trade flows from 48% to 77%, depending on the level of restrictiveness. We estimate the elasticity of seaborne trade flows with respect to distance to be nearly unity, and are able to disentangle the direct effect of distance from the one that is operating indirectly through higher maritime transport costs. Since the bulk of global merchandise goods trade is seaborne, the magnitude of frictions identified in this paper and their spatial distribution have ramifications for connectivity and growth.
