Export Sector Dynamics and Domestic Growth: The Case of Colombia

Analyses of Colombian data have generally failed to confirm the hypothesis of export-led growth. This paper generates several measures of export diversification and structural change in exports, and argues that these measures are useful in assessing growth externalities generated by the export sector. In a simultaneous-equations framework, increases in the rate of export structural change are associated with accelerated Colombian GDP growth. Export diversification, by contrast, is not a source of economic growth, and the reduced-form relationship between aggregate lagged export growth and GDP growth is weak.     

A further examination of the export-led growth hypothesis

This article challenges the common view that exports generally contribute more to GDP growth than a pure change in export volume, as the export-led growth hypothesis predicts. Applying panel cointegration techniques to a production function with non-export GDP as the dependent variable, we find for a sample of 45 developing countries that: (i) exports have a positive short-run effect on non-export GDP and vice versa (short-run bidirectional causality), (ii) the long-run effect of exports on non-export output, however, is negative on average, but (iii) there are large differences in the long-run effect of exports on non-export GDP across countries. Cross-sectional regressions indicate that these cross-country differences in the long-run effect of exports on non-export GDP are significantly negatively related to cross-country differences in primary export dependence and business and labor market regulation. In contrast, there is no significant association between the growth effect of exports and the capacity of a country to absorb new knowledge.     

Is aid for trade effective? A panel quantile regression approach

This paper investigates whether Aid for Trade (AfT) leads to greater exports in recipient countries. Using panel quantile regression and two strategies to address endogeneity (AfT lagged by two periods and dynamic OLS), our results suggest that total AfT disbursements promote the export of goods and services mainly for the lower quantiles (0.1, 0.25, 0.50) of the conditional distribution of exports. Hence, countries that export less in volume are those benefitting most from AfT. This effect is mainly driven by the impact on exports of goods rather than on that of services. We also investigate which types of AfT are effective when endogeneity is controlled for. The main results show that whereas aid to improve trade policy and regulation is associated with higher exports for all quantiles, aid used to build infrastructure is found to affect exports at only the lowest tails of the distribution (0.10–0.35) and aid to build productive capacity is generally more effective for the lower quantiles of the export distribution (0.10–0.50). In contrast, aid disbursed for general budget support (an untargeted type of aid) is not associated with greater export levels. This finding holds irrespective of the quantile.     

Effects of Primary Exports on Industrial Exports and GDP: Empirical Evidence

This paper analyzes the effects of the growth of nonfuel primary exports on the growth of industrial exports and GDP in 74 economies between 1965 and 1992. There is clear evidence of positive effects, both in the short term and in the long term, of the growth of primary exports on the growth of industrial exports and GDP in more than two-thirds of the economies. Therefore, governments in developing countries should not discriminate against the export of primary products, as some earlier studies suggest. Instead, they should adhere to policies that aim at export promotion.     

Dutch disease and the oil boom and bust

This paper examines the impact of the oil price boom in the 1970s and the subsequent bust on non‐oil economic activity in oil‐dependent countries. During the boom, manufacturing exports and output increased significantly relative to non‐oil countries. These measures decreased gradually during the bust and subsequent period of low prices, displaying a positive relationship with oil prices. However, exports of agricultural products sharply decreased during the boom. Imports of all types of goods displayed strong pro‐cyclicality with respect to oil prices. The results suggest that increased local demand and investment spillovers from the windfall resulted in increased manufacturing activity.     

Exports and innovation: the role of heterogeneity in exports

This paper examines whether and how heterogeneity in exports affects firms’ innovations in China. Using comprehensive transaction-level trade data from China Customs to construct various dimensional measures exports, empirical results obtained from a matched firm-transaction panel data find that exports overall have a positive impact on promoting innovations in terms of R&D and new product sales. The innovation-enhancing effect of exports depends on the heterogeneity in exports. Firms with greater varieties of exports, more market diversification, and higher export quality are associated with a higher R&D propensity and more new product sales, while process exports are found a negative association with innovations.     

Institutional foundations of export diversification patterns in oil-producing countries

While it is well known that resource exporting countries have higher export concentration, it is lesser known that there is substantial variance in export concentration fortunes within resource-based countries. Using several estimation techniques and other sensitivity checks, this paper offers a new explanation for success and failure in export diversification patterns in oil countries, an explanation which has an institutional and political background. In measuring the number of years between the beginning of oil production and the attainment of political independence in oil developing countries, we found that the greater the number of years, the higher the degree of export diversification ceteris paribus. Our interpretation of this result is grounded in an analysis of political constraints to diversification in resource-based countries. Institutions, unfavorable to diversification, which arose from the pre-independence period, were blocked in their positive evolution by national political elites in the post-independence period. This result contributes to a better understanding of the dynamics of institutions in resource-based countries.     

Non‐linear effect of exchange rate volatility on exports: the role of financial sector development in emerging East Asian economies

This paper empirically examines the role of financial sector development in influencing the impact of exchange rate volatility on the exports of five emerging East Asian countries – China, Indonesia, Malaysia, the Philippines and Thailand – using a GMM‐IV estimation method. The results indicate that the effect of exchange rate volatility on exports is conditional on the level of financial sector development. The less financially developed an economy, the more its exports are adversely affected by exchange rate volatility. In addition, a stable exchange rate seems to be a necessary condition to achieve export promotion via a currency depreciation in these economies.     

Impact of oil price changes on Turkey’s exports

Substantial decline in oil prices observed since the second half of 2014 has brought forward discussions on the impact of oil prices on the external balance. This decline is expected to shift real income from oil exporter countries to oil importer countries. In this context, we study the effect of change in oil prices on Turkey’s exports taking into account the fact that Turkey’s export to oil exporting countries has approximately one-third share in total exports, while export to oil importing countries has a share of two-thirds. At the first step, we analyse the effect of oil prices on economic growth of trade partners of Turkey, where countries are grouped according to their net oil export position. We find that the effect of oil prices on different country groups’ growth is asymmetric. In the second stage, for two groups of countries, we estimate growth-export elasticity through Turkey’s export demand function. Finally, we calculate the net effect of oil prices on exports considering different income effects caused by oil price change on each country groups. Results indicate that the net effect of oil prices on the exports is limited given the current export shares.     

The direction of developing country trade: Empirical evidence of differences between South-South and South-North trade

Declining market opportunities in Northern markets led to views that greater South-South trading might provide an alternative growth stimulus. This paper analyses the characteristics of South-South trade in manufactures and recent changes in the level of such trade to help clarify the potential of greater self-reliance within the South. South-South trade is found to be more intensive in the use of both physical and human capital, hence less rational from the static comparative advantage viewpoint than South-North trade. There is indirect but strong evidence that exporting countries with greatest orientation towards the South are those with greater distortions, less rapid movements up the ladder of comparative advantage, and weaker export performance. Finally, it is observed that the recent boom in South-South trade is largely explained by simple market size effects: very rapid growth of rich oil-exporters and the faster GNP growth of developing compared to developed countries. The paper concludes that while South-South trade of about the present magnitude-one of greater developing country exports - is certainly rational, there is little evidence to support views that greater South-South trade should be especially promoted. Arguments of dynamic comparative advantage may favor South-South trade, but so far these have been more speculative and not yet well researched empirically.     

Export Growth and Domestic Performance

A VAR approach is used to analyze the effects of export growth on the evolution of GDP, domestic employment, and investment in 39 economies. The results strongly support the export-led growth hypothesis. Export growth affects GDP growth positively in 30 countries. In six countries, all of them inward-looking, the effects are negative. For these countries, and for these countries alone, export growth has a negative effect on the evolution of both domestic employment and investment. This also suggests the importance of the indirect effects of exports on GDP growth.     

What does export diversification do for growth? An econometric analysis

It is frequently suggested that export diversification contributes to an acceleration of growth in developing countries. Horizontal export diversification into completely new export sectors may generate positive externalities on the rest of the economy as export oriented sectors gain from dynamic learning activities due to contacts with foreign purchasers and exposure to international competition. Vertical diversification out of primary into manufactured exports is also associated with growth since primary export sectors generally do not exhibit strong spillovers. Yet there have been remarkably few empirical investigations into the link between export diversification and growth. This paper attempts to examine the hypothesis that export diversification is linked to economic growth via externalities of learning-by-doing and learning-by-exporting fostered by competition in world markets. The diversification-led growth hypothesis is tested by estimating an augmented Cobb–Douglas production function on the basis of annual time series data from Chile. Based on the theory of cointegration three types of statistical methodologies are used: the Johansen trace test, a multivariate error-correction model and the dynamic OLS procedure. Given structural changes in the Chilean economy, time series techniques considering structural breaks are applied. The estimation results suggest that export diversification plays an important role in economic growth.     

Multidimensional financial development,exporter behavior and export diversification

Financial development shapes export sector performance because exporters need external finance and face credit constraints. Previous empirical research has relied largely on single-country studies. The Exporter Dynamics Database (EDD), which features firm-level exports from over 60 countries, reveals differences in the microstructure of the export sector across countries. In this paper, we first provide new evidence that these differences are related to cross-country variation in financial development and structure. Second, we combine the EDD and multidimensional data on financial development with a global database on export diversification. This study is the first to examine how macrolevel export diversification is determined by the microcharacteristics of the export sector. This approach is novel in the empirical literature on export diversification. According to our cross-country analysis, access to domestic financial services positively contributes to export diversification by increasing the number of small exporters, as financial services ease the credit constraints these exporters face.     

东北亚国家出口多样化与经济增长的关系——基于动态面板数据的系统GMM估计

利用1996—2010年东北亚国家的贸易数据,验证了出口多样化与人均GDP之间的关系,并采用系统广义矩方法建立动态面板数据模型,估计了出口多样化对经济增长的贡献。结果表明:就东北亚单个国家而言,出口多样化与人均GDP之间呈U型变动关系,但就东北亚整体而言,这种U型关系并不明显;从东北亚国家的经验来看,出口多样化对经济增长具有积极作用;目前我国出口正处于从多样化向集中化转变的上升阶段,尚未达到U型曲线的拐点。     

Trade Strategy, Investment and Exports: Another Look at East Asia

The export booms in South Korea and Taiwan starting in the early 1960s are anomalous when compared with later export booms in non-East Asian countries such as Chile and Turkey. First, these booms have taken place in the context of comparatively small changes in relative prices in favor of exportables. Second, they have been associated from the start with booms in investment. This paper offers evidence and a formal model to suggest that exports in East Asia may have been driven by an increase in the profitability of investment, with outward orientation a consequence of the investment boom rather than its instigator.     

Implications of Changes in the composition of Australian Exports for Export Sector Instability

Variability in export returns is a major source of instability in the Australian economy and, in the presence of price and wage rigidities, may be a substantial cause of social costs. There have been calls for explicit policies to change Australia's pattern of exports away from traditional agricultural and mineral exports. In this article, the implications of changes in the pattern of Australian exports have been examined taking into account the variability of each category and the correlations between categories. From the results it appears that the diversification from rural to mineral exports since 1970 has substantially reduced the variability of export returns. While rural exports remain the most variable component of the total, a reduction in the rural share of total exports and a corresponding expansion of Australias traditional manufactured exports would appear to have surprisingly little effect on export variability.     

Power laws in EU country exports

International trade flows are highly concentrated in the top units of analysis. In this paper, we study the size distribution of exports at the product level, using Comext data for the 28 EU countries over the period 2002–2014. We fit power law relationships running log rank–log size regressions. The estimated Pareto exponent may be interpreted as a single measure of the inequality between the top products; it thus constitutes an alternative to other measures of export diversification. The Pareto exponent estimates are quite stable for most EU countries between 2002 and 2014. However, some countries stand out for their increase or decrease in the Pareto exponent. Some preliminary evidence suggesting negative correlation between volatility in EU country exports and export diversification at the product level is also provided.     

Exchange rate and foreign GDP elasticities of Swiss exports across sectors and destination countries

This article uses a detailed breakdown of Swiss trade flows to identify how the impact of the two main determinants of Switzerland’s exports – foreign demand and the real exchange rate – varies across sectors and export destinations. Our main findings are that (i) both foreign demand and exchange rate elasticities vary substantially across both export sectors and export destinations. (ii) Foreign demand trends are more important for structural considerations than the exchange rate. This is due to the fact that exports of the two largest export sectors are relatively sensitive to long-run foreign demand developments while they are relatively insensitive to changes in the exchange rate. (iii) The sectoral structure of Switzerland’s exports has shifted towards goods that have a lower short-run demand elasticity and a higher long-run demand elasticity. Goods exports are thus less influenced by business cycle fluctuations while they benefit more from long-term growth trends. (iv) The export share of sectors with a relatively low exchange rate elasticity has increased. However, this result is mainly driven by the strong rise in exports of chemicals and pharmaceuticals as well as precision instruments and watches, which are also the two important sectors responsible for the Swiss trade surplus.     

The impacts of China on economic growth: Evidence for Brazil,Chile, and Peru

This study empirically analyzes the direct impacts derived from the swift increase in exports to China (referred to as “the impact of China”) on the economic growth of three selected South American countries, Brazil, Chile, and Peru, during the commodity boom between 2001 and 2008. The results stemming from the balance-of-payments-constrained growth model suggest that the magnitude of China’s impact was less than 1 percent, although it ranged from the largest to the second largest impact among all trading partners for the three countries. The estimated balance-of-payments growth rate of domestic income is lower than the real growth rate of domestic income. This is because the growth rates of the export volumes were not sufficient even during the commodity boom, on account of the continued increasing trends of income elasticity of demand for imports. Furthermore, the income elasticities of demand for imports from China were especially high. Therefore, the three countries will continue to face further increase in the income elasticity of demand for imports as well as a stagnant growth rate of export volumes. Thus, the balance-of-payments position will continue to be the main growth constraint for these countries.     

Openness in the Canadian economy: 1870–1988

The causal relation between openness and GDP and between exports and imports are examined. Causality test carried out in growth rates showed that over the period 1870–1988 openness, both narrowly and broadly defined, Granger-causes GDP growth; tests for the inverse causality produced mixed results, validating causality from GDP growth to export plus import growth, but rejecting causlaity from GDP growth to export growth; it was also found that export growth causes import growth, but not the opposite. Causality tests over four subperiods indicated the importance of openness for only the earliest phase of Canadian economic development. While the absence of causality in the later subperiods is largely compatible with the experience of the industrial countries, no meaningful comparison can be made between the experience of Canada and that of developing countries owing to causality variations of openness and to large differences in resource endowments.
