Creative destruction and unemployment in an open economy model

I develop a model of endogenous economic growth and search and matching frictions in the labour market. I study the effect of trade liberalization between two identical economies on long‐run unemployment and show that bilateral trade liberalization has a steady state effect on unemployment that is negative for countries with a relatively larger R&D sector and positive for countries with a smaller R&D sector.     

Trade Liberalization and Productivity Growth

This paper presents a trade model with firm‐level productivity differences and R&D‐driven growth. Trade liberalization causes the least productive firms to exit but also slows the development of new products. The overall effect on productivity growth depends on the size of intertemporal knowledge spillovers in R&D. When these spillovers are relatively weak, then trade liberalization promotes productivity growth in the short run and makes consumers better off in the long run. However, when these spillovers are relatively strong, then trade liberalization retards productivity growth in the short run and makes consumers worse off in the long run.     

Strategic R&D Commitment and the Gains from Trade

This paper examines how trade liberalization affects innovation, profits and welfare in a model of reciprocal markets when firms pre‐commit to research and development (R&D). We establish that the equilibrium is not always unique and show that, with trade, R&D commitment leads to higher levels of innovation, lower profits, higher consumer surplus and higher welfare than when R&D is chosen simultaneously to output levels. Furthermore, if the effectiveness of R&D is sufficiently high, trade always yields higher welfare than autarky, implying that R&D commitment may significantly enhance the welfare gains from trade liberalization.     

A North–South model of outsourcing and growth

In this paper, I formulate a simple North–South R&D‐based growth model where final goods firms in the North endogenously determine the range of international outsourcing of intermediate goods to the South. I show that a fall in the trade cost (through trade liberalization) of intermediate goods in the North: (i) reduces the wage of the North relative to that of the South; (ii) increases the outsourced variety of intermediate goods in the North; and (iii) stimulates Northern R&D activity and economic growth in both countries. By conducting welfare analysis, I also show that a decline in the trade cost of intermediate goods in the North improves welfare in the South more than in the North.     

Trade and firm heterogeneity in a Schumpeterian model of growth

The present paper explores the effect of trade liberalization on the level of productivity as well as the rate of productivity growth in an R&D-based model with heterogeneous firms. We introduce new and plausible features that are absent in existing studies. First, technical progress takes the form of continual quality improvement of products over time. Second, firm entry and exit are endogenously determined due to creative destruction of products. In this framework, we demonstrate that a lower transport cost or export sunk cost unambiguously reallocates resources to R&D and top-quality product industries from low-quality good industries. This means that trade liberalization increases the rate of technical progress as well as the level of manufacturing productivity. These results are found to be robust in an extended model with population growth without scale effects.     

Does international openness affect the productivity of local firms?

This paper examines how international openness can change firm productivity in south‐eastern Europe (SEE), a crucial question for middle‐income countries. Using firm‐level data for six transition economies over the 1995–2002 period, we identify whether foreign ownership and propensity to trade with more advanced countries can bring about higher learning effects. We find that: (i) foreign ownership has helped restructure and enhance the productivity of local firms in four out of six countries; (ii) exporting to advanced markets has a larger impact on productivity growth in four countries, especially when the firm's absorptive capacity is taken into account; (iii) in contrast, exporting to the less competitive markets of the former Yugoslavia seems to negatively affect productivity growth in three countries; and (iv) learning effects from importing are similar to those from exporting. Our results suggest that trade liberalization is not uniformly beneficial. Regional composition of trade flows and absorptive capacity of local firms matter. Thus, trade liberalization within the SEE region may not provide a substitute for a general trade liberalization which includes access to the more competitive markets of countries belonging to the Organization for Economic Co‐operation and Development.     

Growth in transition economies: A trade policy perspective1

This paper examines the influence of trade liberalization on GDP growth during the transition from communism. The level of trade liberalization is found to raise the growth rate, particularly in the early part of the transition and for the countries nearest to the European Union. For the remaining countries and for the later transition period, the positive influence of trade reform on growth requires the negative effect of the interaction between trade reform and privatization to be taken into account. Even with the interaction terms the effect of trade liberalization is not statistically significant in the later transition period.     

A Rationale for Infant-Industry Protection and Gradual Trade Liberalization

A two-final-good, one-primary-factor, small–open endogenous growth model is constructed based on R&D. The model yields two steady states with different growth rates as potential equilibria. Depending on history and the external environment, the economy may fall into the poverty trap in free trade. However, a temporary trade policy can release the economy from the poverty trap. Moreover, the optimal trade policy is gradual trade liberalization with the rate of protection kept to a minimum.     

Growth and Deeper Regional Integration in a Three-Country Model

An endogenous growth model of three countries is used to investigate the dynamic effects of deeper economic integration between two countries in the presence of an outside world. The paper looks at the long-run effects of inner-union trade liberalization, the union's external trade policy, and of the relaxation of the inner-union barriers to migration. It is shown that regional integration via inner-union trade liberalization can lead very well to a decline of the steady-state growth rates.     

Trade Liberalization and Technology Diffusion

The paper considers the role of technology diffusion and trade liberalization for the catching‐up of structurally backward countries. A New Economic Geography model is presented that accounts for firm entry/exit and international mobility of skilled labor employed in public R&D sectors. This raises the traditional agglomeration effects in a core–periphery setting as firms and mobile factors usually cluster within spatial agglomerations. With international technology diffusion, however, there is a counteracting effect on the traditional agglomeration effects as firms in the periphery also benefit from increasing R&D expenditures in the core lowering entry costs for firms. It is found that the catching‐up of structurally backward countries is spurred not only as a result of trade integration but also because of technology diffusion.     

R&D Policies and Endogenous Growth: A Dynamic General Equilibrium Analysis of the Case for Canada*

This paper utilizes a general equilibrium R&D model of endogenous growth via increasing capital variety to examine the impact of alternative policies on productivity and economic growth. The model is calibrated using data from the Canadian economy. Findings reveal that direct incentives such as subsidies to R&D activities would have the highest productivity impact on the Canadian economy, that an increase in subsidies to the users of R&D capital (output) would have a positive but smaller impact, and trade liberalization would have minimal effects on productivity growth via its impact on international R&D spillovers.     

Trade Policy and Productivity Growth in OECD Manufacturing *

Trade liberalization may promote economic growth in a number of ways, including by accelerating the rate of technological change. Firms that face more intense import competition may be spurred to greater rates of innovation; firms which export may absorb new technologies through their contact with international markets. This paper examines evidence on trade policy and productivity growth for a sample of thirteen OECD countries and including eighteen manufacturing sectors, using data primarily from the 1980s. Within individual sectors, there are strong productivity convergence effects within the OECD. After controlling for convergence, we find a positive association between high rates of productivity growth and low tariffs, and between high productivity growth and strong export performance. We found no particular association between high productivity growth and import penetration. The results are consistent with the possibility of positive linkages between trade liberalization and accelerated productivity growth. [F1, O4]     

Endogenous Free Trade Agreements and Foreign Lobbying

This paper assesses the political viability of free trade agreements (FTAs) in the presence of lobbying by organized foreign interest groups. The assessment is based on a model in which external tariffs and the decision to form an FTA are endogenously determined. The findings demonstrate that, in the presence of an organized lobby group in a prospective partner country, an FTA may initiate an increase in the level of protection against imports from third countries and impede trade with non‐member countries. Further, this study finds that a foreign lobby may encourage the local government to enter a welfare‐reducing trade‐diverting FTA. Finally, this paper shows that an FTA increases the lobbying power of the organized lobby groups of the member countries, which can potentially obstruct the viability of welfare‐improving multilateral trade liberalization.     

Water on Fire: Gains from Electricity Trade

In light of the ongoing liberalization of electricity trade in the Nordic countries, and perhaps in Northern Europe, we argue that gains from electricity trade may be different from those traditionally associated with comparative advantages and economies of scale. In particular, we consider gains arising from the exploitation of technological complementarities between hydro and thermal systems. Our theoretical framework highlights essential features of the two systems and allows for an analysis of effects of trade. We study three trading regimes, which may arise either endogenously or because of trade regulations: day–night power exchange, seasonal energy banking and unbalanced trade. The analysis suggests that gradual trade liberalization may be costly.     

Distance to Frontier and New Import Growth

In a panel‐data study involving product‐level import data for 48 developing countries that underwent substantial trade liberalization between 1989 and 2001, this study finds that the growth of trade in new goods imported following major trade liberalization is related to the state of technology that existed just before liberalization. The study develops two new measures of the extensive margin. Findings indicate that greater is the distance of a country from the world technology frontier, the faster is its growth of new goods imports. This indicates a higher cost of trade protection for countries further away from the world technology frontier.     

Neighbour-Immiserizing Growth: The Asian Crisis

This paper investigates the effects of population growth and China's entry into the world trading regime on the North and the South. In the absence of the terms of trade effect, population growth reduces the standard of living and causes a decline in welfare. Unilateral trade liberalization of China will worsen the terms of trade for other countries in the South, but will improve those for the North. Thus, population control is an important means to close the gap in per capita income between developing and developed economies. Trade liberalization by developing countries may not necessarily induce income convergence. JEL Classification Number: F1.     

Advantages of backwardness and forwardness with shifting comparative advantage

This paper develops a multi-sector endogenous innovation model that is able to account for the dynamics of comparative advantage of each sector within the economy. The model in this paper assumes that two kinds of learning effects exist in R&D: advantages of backwardness and forwardness. It is shown that if the economy is divided into advanced and backward sectors, in the latter sectors, the advantage of backwardness dominates, leading to cyclic repetition of comparative advantage. However, in the former sectors, the advantage of forwardness becomes more significant, so comparative advantage among these sectors stabilizes. Thus, the direction of learning spillovers has a critical effect on the dynamics of comparative advantage. Given this result, it is shown that only R&D policies for the marginal sector are effective in facilitating economic growth. If a decision is made to facilitate R&D investment within advanced sectors, R&D taxes, rather than subsidies, should be imposed on this marginal sector. Moreover, it is shown that trade liberalization does not affect the intrinsic dynamics of comparative advantage among surviving sectors in the economy if the locus of this marginal sector does not change significantly after trade liberalization.     

Impact of Regional Economic Integration in East Asia

The current study evaluates the economy wide impact of trade liberalization in the ASEAN region along with China, Japan and Korea (ASEAN + 3) by the year 2020 using the GTAP framework. The study also assesses the environmental impact of the trade liberalization in the region focusing on the seven environmental indicators (CO₂, CH₄, N₂O, BOD, COD, Suspended Solid and Industrial Waste). The result shows that the countries under agreement (ASEAN + 3) will benefit with increased output, expansion of trade and welfare due to trade reforms. Further, the integration will increase the global welfare, although the regions not under agreement in the world will show a decline in output growth. Vietnam will be gaining with the highest output growth among the ASEAN region; however, the impact on the environment would not be favourable. The environmental impact reveals a mixed outcome for participating countries under the agreement. The paper provides useful insight in pursuing greater trade liberalization among the countries under the study.     

Trade openness and economic growth: a cross-country empirical investigation

This paper demonstrates that trade liberalization does not have a simple and straightforward relationship with growth using a large number of openness measures for a cross section of countries over the last three decades. We use two groups of trade openness measures. The regression results for numerous trade intensity ratios are mostly consistent with the existing literature. However, contrary to the conventional view on the growth effects of trade barriers, our estimation results show that trade barriers are positively and, in most specifications, significantly associated with growth, especially for developing countries and they are consistent with the findings of theoretical growth and development literature.     

知识溢出下增长收敛的复杂性

在知识经济条件下,贸易自由化能否对一个国家的产出水平产生影响,能否为国际经济带来收敛,这是一个重要问题。文章通过假设国家之间构成一个知识网络,贸易中存在非线性的知识溢出,模拟了单边或多边关税下调对一个国际经济增长的收敛行为。研究结果表明,进入WTO体系后关税下调并不总意味着收敛的出现,收敛性依各经济体的初始状态和学习能力的大小而出现复杂行为,在知识网络体系单元取向上,网络的溢出参数——学习能力是决定性因素。多区域系统一旦出现收敛,则不会以牺牲富国利益为代价,即收敛是以低水平稳态向高水平稳态转移的形式出现的。
