Oil Discovery,Political Institutions and Economic Diversification

Diversification is touted as a desirable policy objective for oil‐rich nations because it reduces exposure to volatility. However, the empirical relationship between petroleum and diversification is not well understood. Here, we test the effect of giant oil discoveries on diversification using a panel dataset of 136 countries observed over the period from 1962 to 2012. We notice non‐oil sector export concentration 8 years after a discovery. However, we do not observe any effect on the structure of employment in non‐resource and manufacturing sectors. Democratic political institutions moderate the export and employment concentration effects of petroleum discovery.     

EXPORT DIVERSIFICATION AND EXPORT PERFORMANCE BY DESTINATION COUNTRY

The main focus of this paper is the relationship between export diversification and export performance. The key difference with respect to the previous literature is that export diversification is measured and related to export volume by destination country. The approach is empirical and an aggregate export demand setting is adopted to test the significance and influence of export diversification, measured via the Herfindahl index, on export performance by destination country. The econometric estimation is performed using export data for Spain to its partner countries for the period 1999–2011. The main finding is the positive relationship between Spanish export concentration and export performance by destination market. This finding is shown to be robust to several econometric specifications.     

Trade openness reduces growth volatility when countries are well diversified

This paper addresses the mechanisms by which trade openness affects growth volatility. Using a diverse set of export concentration measures, we present strong evidence pointing to an important role for export diversification in conditioning the effect of trade openness on growth volatility. Indeed, the effect of openness on volatility is shown to be negative for a significant proportion of countries with relatively diversified export baskets.     

Kicking a crude habit: diversifying away from oil and gas in the twenty-first century

Abstract

This article investigates the correlates of diversification away from oil and natural gas dependence in the context of the twenty-first century resource boom (and bust). In a sample of 40 oil- and gas-dependent economies, the majority showed significant sectoral diversification of GDP, but exports remained highly concentrated in fuel exports. Regression analysis indicates that countries that began the boom with higher levels of oil and gas dependence, poorer countries, and those with significantly larger- or smaller-than-average populations were more successful in diversifying their GDP during the commodities boom. Governance matters – more effective, capable bureaucratic structures are associated with greater GDP diversification away from oil and gas – though the effects are not uniformly positive. For any given level of government effectiveness, stronger rule of law is associated with less GDP diversification. Education appears to affect GDP and export diversification differentially. Consistent with endogenous growth theory, countries with more educated populations saw greater growth in their nonresource sectors than countries with less educated populations, though education is associated with greater export concentration. Internal economic diversification in the twenty-first century has been less a matter of policy formation and implementation, and more a matter of factors that shape the policy-making environment.     

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.     

What drives cross-country differences in export variety? A bilateral panel approach

A worldwide event like the 2020 Coronavirus outbreak can only reinforce the interest in modelling trade diversification as a key factor in countries’ vulnerability to external shocks. This paper adopts a detailed relative framework to study the determinants of product-level export variety in a large bilateral panel of developing and developed economies (16,770 country pairs in the period 1988–2014). We find that country pairs characterized by large differentials in productivity and in the makeup of the labour force differ in export variety patterns. This result holds after controlling for other endowments and for trade costs. Further, productivity plays a significant role in the reduction of export variety dissimilarities between countries belonging to different income groups. Hence, without successful technological convergence the low-income economies will not be able to reduce their exposure to export risk.     

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。     

Export surges

How can developing countries stimulate and sustain strong export growth? To answer this question, we examine 92 episodes of export surges, defined as significant increases in manufacturing export growth that are sustained for at least 7 years. We find that export surges in developing countries tend to be preceded by a large real depreciation, which leaves the exchange rate significantly undervalued. In contrast, in developed countries, the role of the exchange rate is less pronounced. We examine why the exchange rate is important in developing countries and find that the depreciation is associated with a significant reallocation of resources in the export sector. In particular, depreciation stimulates entry into new export products and new markets. These new exports are important, accounting for over 40% of export growth on average during the surge in developing countries. We argue that a large real depreciation induces firms to expand the product and market space for exports.     

Foreign ownership and corporate income taxation: An empirical evaluation

Foreign ownership allows countries to effectively export part of their corporate tax burden. Hence, countries with high foreign ownership are expected to impose relatively high corporate taxes. The findings of this paper suggest that there indeed is an economically significant positive relationship between foreign ownership and tax burdens in Europe. Already significant foreign ownership levels in Europe offer an explanation for the absence of a ‘race to the bottom’ in corporate tax levels.     

Oil and ethnic inequality in Nigeria

Although it is known that ethnic biases exist in Africa, less is known about how these respond to natural resource prices. Many ethnically fragmented African countries depend on a small number commodities for their export base. Oil prices experienced in early life predict differential adult outcomes across Nigerian ethnic groups. Our difference-in-difference approach compares members of southern ethnicities to other Nigerians from the same birth cohort. This North-South distinction mirrors several economic, political, and religious cleavages in the country. Greater prices in a southern individual’s birth year predict several relative outcomes, including reduced fertility, delayed marriage, higher probabilities of working and having a skilled occupation, greater schooling, lower height, and greater BMI. These microeconomic impacts are explained by macroeconomic responses to oil prices; relatively, urban incomes increase, food production declines, and maternal labor intensifies in the South.     

Export diversification in a transitioning economy

How does the process of export diversification take place in an economy in transition, especially in light of government policy aimed at trade liberalization? This article examines this question by considering a directed policy effort by Syria – an economy in transition from both economic centralization and resource dependence – to liberalize its trade between 2001 and 2008. In addition to documenting the patterns of diversification at the aggregate level since the implementation of the policy, we also examine factors that are related to diversification at the sectoral level. Our findings suggest that, while Syria has achieved reasonably rapid export diversification, this may to a large extent be the result of structural transformations in the economy, and that further diversification may require continued policy reform designed to strengthen Syria's weak institutional and business environment.     

The quality and variety of exports from the new EU member states

The goal of this article is to evaluate the variety and quality of exports from the new EU member states (NMSs) in the period 1999–2009. The practical relevance of such an analysis is threefold: recent studies underline the importance of export variety for economic growth; empirical results show that export variety was influenced by the EU membership; and looking separately at export quality permits a better understanding of price competitiveness. Our results show that all NMSs significantly increased the average number of brands exported to the EU market, the largest increases being observed in 2004 and after. This indicates that integration into the EU market occurs in the extensive as well as the intensive dimension. We also find that all NMSs increased the average quality of their exports during the decade studied although there are differences between countries. Thus, a large part of the increase in the prices of exports from NMSs resulted from improving quality and did not result in a loss of competitiveness. Finally, estimates of relative quality are much more stable than relative prices, suggesting that our measure of relative quality is better than the traditional proxy.     

The impact of foreign direct investment on horizontal export diversification: empirical evidence

Using data on stocks of Foreign Direct Investment (FDI) from 131 countries spanning the years 1984 to 2004 and the number of products exported by each country, we examine the effect of FDI on horizontal export diversification. To quantify the effects, we utilize parametric (quantile) and semi-parametric econometric methods. Results from both approaches indicate that, in general, an increase in the stock of FDI enhances the horizontal diversification of exports. The actual magnitude of the effect however, varies greatly across countries depending on the existing stock of FDI and stage of diversification, giving rise to an almost inverted U-shaped relationship. A further look at our results provides useful insights on the circumstances under which FDI may aid or inhibit the horizontal expansion of exports.     

The pattern of specialization and economic growth: The resource curse hypothesis revisited

This paper explores the relation between countries’ pattern of trade specialization and long-term economic growth. It shows that countries specializing in the export of natural resource based products only fail to grow if they do not succeed in diversifying their economies and export structure. This conclusion follows from an empirical investigation that has three innovative features. First, it uses a dynamic panel data analysis. Secondly, it employs disaggregated trade data sets to elaborate different measures of trade specialization that distinguish between unprocessed and manufactured natural resource products and are informative about the countries’ trade diversification experience, their link to world demand trends and involvement in intra-industry trade. The final innovative aspect of the paper relates to our empirical findings: it is only specialization in unprocessed natural resource products that slows down economic growth, as it impedes the emergence of more dynamic patterns of trade specialization.     

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.     

Post-Lange Market Socialism: An Evaluation of Profit-Oriented Proposals

In recent years we have observed significant growth in the private sector in many higher education systems around the globe. This growth of private higher education is associated with high political expectations, notably concerning greater choice of programs and greater responsiveness of institutions to students' and labor markets' demands. Looking at the experience of several European and Latin American countries, this study analyzes the patterns of program diversification of public and private higher education and discusses the impact of the private sector for the diversification of higher education's supply. The results show a contrasting picture between political beliefs about privatization in higher education and its actual results, suggesting that private institutions tend to be far more specialized than their public counterparts.     

The curse of aid

Foreign aid provides a windfall of resources to recipient countries and may result in the same rent seeking behavior as documented in the “curse of natural resources” literature. In this paper we discuss this effect and document its magnitude. Using panel data for 108 recipient countries in the period 1960–1999, we find that foreign aid has a negative impact on institutions. In particular, if the foreign aid over GDP that a country receives over a period of 5 years reaches the 75th percentile in the sample, then a 10-point index of democracy is reduced between 0.5 and almost one point, a large effect. For comparison, we also measure the effect of oil rents on political institutions. We find that aid is a bigger curse than oil.     

A new look at the benefits of diversification: lessons from Central America

Recent trends of export diversification in Central America may lower foreign exchange earnings instability there. Four countries–Costa Rica, El Salvador, Honduras, and Guatemala–are analysed across a twenty-year period. The paper uses United Nations Commodity Trade Statistics to explain why Costa Rica and Honduras have enjoyed greater earnings stability in recent years, despite the fact that Honduras has not greatly diversified its export products and markets. Despite the growth of new agricultural and manufacturing goods, traditional primary products still dominate the countries' export portfolios. Specific products within each of the four broad product category groups contribute to the varied country outcomes. Summary statistics from the United Nations (panel) data suggest newer agricultural exports have not stabilized Guatemalan and Salvadoran export earnings, while Honduras has enjoyed relatively stable banana export revenues and Costa Rica has benefited from the smooth flow of microelectronic products. Further panel data regression analysis shows country size and intangible country effects also explain parts of the detrended earnings deviation in addition to product base and level of diversification.     

Classifying exchange rate regimes: Deeds vs. words

Most of the empirical literature on exchange rate regimes uses the IMF de jure classification based on the regime announced by the governments, despite the recognized inconsistencies between reported and actual policies in many cases. To address this problem, we construct a de facto classification based on data on exchange rates and international reserves from all IMF-reporting countries over the period 1974-2000, which we believe provides a meaningful alternative for future empirical work on the topic. The classification sheds new light on several stylized facts previously reported in the literature. In particular, we find that the de facto pegs have remained stable throughout the last decade, although an increasing number of them shy away from an explicit commitment to a fixed regime (“hidden pegs”). We confirm the hollowing out hypothesis but show that it does not apply to countries with limited access to capital markets. We also find that pure floats are associated with only relatively minor nominal exchange rate volatility and that the recent increase in the number of de jure floats goes hand in hand with an increase in the number of de facto dirty floats (“fear of floating”).     

Buyer and Seller Concentration in Global Commodity Markets

In recent years there has been an increased incidence of export restrictions applied by developing countries to commodities and raw materials. Commodity markets may be characterized by concentration on the buyer side, with a small number of transnational intermediary firms purchasing from supplying countries and distributing to the market, and recent work has suggested that export taxes may be an optimal policy to recapture monopsony rent. However, in many commodity markets there are also a limited number of large supplying countries. This paper considers a situation where an oligopsonistic intermediary industry purchases from a small number of supplying countries, the governments of which act strategically in their policy choices both with respect to the intermediaries and any competing suppliers. In the resulting two‐stage game, the paper shows that an export subsidy, rather than an export tax, may arise as the optimal intervention.
