International trade and economic growth: evidence from a panel ARDL-PMG approach

The purpose of this work is to study the impact of trade openness on the economic growth of the countries bordering the Mediterranean using a panel of eight countries from 1975 to 2016. We apply ARDL panel which is a technique recently developed. We study the effects of openness to international trade on economic growth while incorporating economic policy variables. The results show that the variables of commercial and financial openness favor economic growth. The free trade agreements that the European Union has signed with certain countries in the Mediterranean basin are designed above all to encourage greater regional economic integration and an increase in their potential growth. Therefore, our findings show that the financial sector is slow to affect economic growth in these countries. This study reveals that human capital and the investment rate support the economic growth of our sample. In addition, we conclude that a process of economic convergence has begun in these countries. A causal analysis was carried out we found an unidirectional causality ranging from economic growth to trade openness.

     

Testing the Validity of the Simultaneous Openness Hypothesis in Nigeria (1990–2015)

Since the seminal paper by Rajan and Zingales in 2003, a plethora of studies have been motivated to establish whether the simultaneous opening of trade and capital borders leads to financial sector development. We test whether the simultaneous openness hypothesis is valid for Nigeria, with a focus on the banking sector and stock market. Using annual data from 1990 to 2015 and an instrumental variable regression estimation technique, we show that the simultaneous increase of trade and financial openness limits banking sector and stock market development. Thus, there is no empirical evidence to validate the simultaneous openness hypothesis in Nigeria. It also shows that trade openness is more beneficial for banking sector and stock market development in Nigeria than financial openness.     

Does the internet generate economic growth,international trade,or both?

Recent cross country panel data studies find a positive impact of internet use on economic growth and a positive impact of internet use on trade. The present study challenges the first finding by showing that internet use does not explain economic growth directly in a fully specified growth model. In particular openness to international trade variables seem to be highly correlated with internet use and the findings in the literature that internet use causes trade is confirmed here suggesting that internet use impacts trade and that trade impacts economic growth. A simultaneous equations model confirms the positive and significant role of internet use to openness and the importance of openness to economic growth. Internet use shows to be more impacting trade in non-high income countries than in high income countries whereas the impact of trade on economic growth is the same for both income groups.     

贸易开放、投资效率与中国的经济增长——基于“Krueger-Bhagwati”范式的经验研究

本文采取以制度分析为基础的"Krueger—Bhagwati"范式作为理论依托,以Dollar系数作为衡量贸易开放度的指标,对1953~2004年中国贸易开放与经济增长之间的关系进行了回归分析。结果显示,贸易开放促进经济增长的机制在于消除国内市场价格扭曲,减少非生产性寻利行为,提高了投资效率。同时,中国的确存在出口导向型增长,但这种增长方式为满足国外部门需求而挤压国内消费,容易产生经济波动。因此,对进出口采取一致激励的中性贸易体制是现阶段更为理想的体制选择。     

Productivity,Trade, and Institutional Quality: A Panel Analysis

Recognizing that gains historically attributed to trade capture instead the roles of institutions and geography, we estimate the relationship between labor productivity and trade for a panel of countries, 1980 to 2000. We use real and nominal openness as measures of trade. The endogeneity of trade and institutional quality is accounted for with instruments. Our trade instrument is based on a theoretically motivated gravity equation and uses a more comprehensive data set than in related studies. Fixed‐ and random‐effects and system‐GMM panel estimation methods address potential biases associated with cross‐section estimations. We find a robust relationship between real openness and labor productivity from the 1990s. Countries that trade more generate higher levels of productivity, supporting an institutional theory of growth. We find evidence that countries with low‐quality institutions benefit from openness to trade and that the positive effect of trade on labor productivity is lower for more populated countries.     

Dynamic estimation of the relationship between trade openness and output growth in Asia

This paper studies the relationship between trade openness and output growth for a sample of twenty-three Asian countries using both a static OLS and a dynamic ECM estimation models. At the country specific level, the findings of this study provide robust empirical evidence indicating that higher revealed trade openness is not the main engine explaining the Asian economic-growth miracle. In particular, the authors find that physical capital accumulation is at the core of the observed long-run output per worker growth. At the regional level, the authors observe a marked difference between the pre and post 1997–1998 financial crisis, whereas, in the post period, trade openness has a positive and significant effect on output growth. In general, the results from the dynamic estimations prove that the conventional OLS static estimates underestimate the effect of investment on output growth. In addition, the dynamic model allows for a separation of gains from trade between short term and long term. The paper results also provide evidence in support of the idea that, countries with a growing degree of trade openness may experience faster per-capita output growth through gains in productivity associated to capital accumulation, rather than the assumed technological spillover effects from the trading sector. Again, at the regional level in the post financial crisis period both short term and long term gains from trade are relevant to growth. Why more trade does not necessarily imply faster growth at all levels of revealed trade openness growth, remains a conundrum.     

城镇化、贸易开放影响经济增长的差异性研究——基于面板数据FMOLS的再思考

文章以城镇化、贸易开放和经济增长为研究对象,运用协整检验和完全修正的最小二乘法（FMOLS）对我国省际面板数据进行实证分析,表明：我国的城镇化、贸易开放与经济增长之间存在着长期稳定的面板协整关系;城镇化和贸易开放对经济增长都有促进作用,但作用力度有差异;城镇化是经济增长的Granger原因,而贸易开放不是经济增长的Granger原因。     

Macroeconomic Volatility, Trade and Financial Liberalization in Africa

This paper examines the effects of financial and trade liberalization on growth volatility of real output and consumption in Africa. Our results suggest trade liberalization is associated with greater output and consumption growth volatility while financial liberalization increases the efficacy of consumption smoothing and stabilizes income and consumption growth. In addition, we find financial market depth and institutional quality operate jointly with trade and financial openness to reduce volatility in output and consumption growth. There is also evidence that good institutions which foster low inflation levels and volatility promote consumption and output growth stability.     

Institutional Quality and CO2 Emission–Trade Relations: Evidence from Sub‐Saharan Africa

This paper examines the roles of trade, institutional quality and their interactions in explaining carbon dioxide emissions in a panel sample of 40 Sub‐Sahara African countries using the system generalised method of moments. We find that institutional reforms are unequivocally environmental improving. Meanwhile, the impacts of trade on the environment tend to depend on the institutional setting of a country. More specifically, trade openness is harmful to the environment in countries with low institutional quality and beneficial to the environment in countries with high institutional quality. This means that institutional reforms are a perquisite for the countries with low institutional quality to actualise the beneficial environment effect of trade. As for the countries with adequate institutional quality, trade and institutions are reinforcing each other in bringing down pollution. From these results, we conclude that trade openness implemented in a sound institutional setting potentially brings better trade, more growth and better environment.     

The changing geography of world trade: Projections to 2030

Rapid economic growth in Asia (and some other emerging economies) has been shifting the global economic and industrial centres of gravity away from the north Atlantic, raising the importance of Asia in world trade, and boosting South–South trade. This paper examines how trade patterns are likely to change in the course of continuing economic growth and structural changes in Asia and the rest of the world over the next two decades. It does so by projecting a core baseline for the world economy from 2004 to 2030 and comparing it with alternative scenarios, including slower economic growth rates in the ‘North’, slower productivity growth in primary sectors, and prospective trade policy reforms in Developing Asia, without and with policy reforms also in the ‘North’ and in South–South trade. Projected impacts on international trade patterns, sectoral shares of GDP, ‘openness’ to trade, and potential welfare gains from reforms are highlighted, in addition to effects on bilateral trade patterns as summarized by intra- and extra-regional trade intensity and propensity indexes. The paper concludes with implications for regional and multilateral trade policy.     

Does China Transfer Productivity Enhancing Technology to Sub‐Saharan Africa? Evidence from Manufacturing Firms*

Abstract: This paper considers whether trade between China and sub‐Saharan Africa results in productivity‐enhancing technology transfers to sub‐Saharan African manufacturing firms. As trade flows between countries potentially results in interactions that lead to technological improvements in the production of goods and services, we parameterize the level of total factor productivity for African manufacturing firms as a function of foreign direct investment flow, and for the country in which it operates, trade openness with China, and its interaction with foreign direct investment. With micro‐level data on manufacturing firms in five sub‐Saharan African countries, we estimate the parameters of firm‐level production functions between 1992 and 2004. Our parameter estimates reveal that across the firms and countries in our sample, there is no relationship between productivity‐enhancing foreign direct investment and trade with China. In addition, increasing trade openness with China has no effect on the growth rate of total factor productivity. To the extent that total factor productivity and its growth is a crucial determinant of economic growth and living standards in the long run, our results suggest that increasing trade openness with China is not a long‐run source of higher living standards for sub‐Saharan Africa.     

Stock Returns and Exchange Rate Nexus in Ghana: A Bayesian Quantile Regression Approach

This paper presents analysis of the relationship and dependence structure between stock returns and exchange rates in Ghana using data of daily periodicity from January 4, 2011 to July 31, 2014. Analyses are conducted by means of Bayesian quantile regression (QR) technique and multiple causality tests. Our findings suggest high dependence of the equity market on the foreign exchange market in Ghana, and that the link between the two markets follows the international trade‐oriented model more than the portfolio balance theory. We report that among the six exchange rates used, only the cedi–dollar registers instantaneous effect on the equity market.     

Trade Openness and Growth: Who Benefits?

We investigate the relationship between economic growth andforeign trade, testing whether the benefits of trade vary overtime and across countries. Our results confirm previous findingsthat specialization in primary exports is bad for growth. Whiletrade openness promoted convergence in the 1960s and 1970s,we find that since 1980 the benefits of trade accrued mostlyto the richer economies, with little benefit to the less developedeconomies. Most of the dynamic benefits of trade are obtainedthrough productivity growth, with a small contribution comingthrough increased investment.     

Determinants of Trade Misinvoicing

Trade misinvoicing should be seen as an element of de facto capital account openness. Traditional explanations for trade misinvoicing??high custom duties and weak domestic economies??are less persuasive in a world of high growth emerging markets that have low trade barriers. We construct a 53-country data set over a 26?year span, covering both industrialized and developing countries, to study the phenomena of export and import misinvoicing. Capital account openness, differentials in interest rates, political stability, corruption, indebtedness and the exchange rate regime are identified as factors related to misinvoicing.     

Free trade agreements and world obesity

We study the causal link between trade openness via free trade agreements (FTAs) and obesity rates. When applying a difference-in-differences approach by exploiting the year a country entered a free trade agreement with the United States during the period 1990–2016. We find a positive and causal impact of FTAs on obesity rates, which are statistically and economically significant. We show that our findings are robust to placebo tests, the use of synthetic control methods, and a maximized sample. Furthermore, we show that when using an event studies approach the equal trends assumption holds.     

Skill, trade, and international inequality

Heckscher-Ohlin trade theory suggests that greater opennesstends to enlarge inter-country differences in stocks of skill(or human capital), which new growth theory suggests would causeinter-country divergence of per capita incomes. Econometricanalysis of data on about 90 countries during 1960-90 confirmsthat greater openness tends to cause divergence of secondaryand tertiary enrolment rates between more-educated and less-educatedcountries, and also between land-scarce and land-abundant countries.These findings may have implications for the optimal choiceof trade policies by poor countries.     

Re‐Visiting Financial Development and Economic Growth Nexus: The Role of Capitalization in Bangladesh

This paper revisits the relationship between financial development and economic growth in Bangladesh by incorporating trade openness in production function using quarter frequency data over the period of 1976‐2012. We applied combined Bayer–Hanck cointegration approach to examine cointegration among the series. Our empirical evidence suggests that development of financial sector facilitates economic growth but capitalization impedes it. In addition, trade openness stimulates economic growth. Labour is also positively linked to economic growth. The vector error correction model Granger causality results divulge that financial development causes real per capita gross domestic product (GDP) growth, and resultantly, real per capita GDP growth causes financial development in a Granger sense. The results also show that trade and labour Granger cause economic growth. The findings of the paper provide insights for policymakers to use financial development and trade openness as a tool for sustained economic growth in the long run. The paper also suggests policymakers to utilise capitalization in a way that is beneficial for economic growth of Bangladesh.     

The effect of financial deepening on inequality: Some international evidence

This paper uses an unbalanced panel data analysis of 126 countries for the period 1963–2002 to analyze the effects of financial deepening on inequality. The principal findings can be summarized as follows: (1) financial deepening reduces inequality; (2) economic growth reduces the equalizing effects of financial deepening; (3) inequality increases with an increase in trade openness; (4) the disequalizing effects of trade openness decrease as a country grows; (5) financial deepening and trade openness therefore have asymmetric effects on inequality; and (6) these effects are robust to the choice of financial variables, inequality measures, and model specifications.     

外商直接投资与技术外溢效应——基于分位数回归法

基于分位数回归法。本文考察了外资对中国工业部门的技术外溢效应。研究结果表明：人力资本、投资环境的改善有利于FDI的技术外溢，而市场竞争、技术差距和经济开放度的提高则不利于FDI的技术外溢：人力资本和投资环境的正向影响分别在内资工业产出条件分布的高端和低端最为显著：经济开放度和技术差距的负向影响分别在条件分布的低端和高端时最为显著；而市场竞争对外溢的负向影响则在条件分布的中间位置时最显著。
