Extent and evaluation of protection in developing countries

Tariff protection and nontariff barriers are higher in developing countries than in industrial nations. The tendency of protection to decline with a higher level of development can be explained by the role of import taxes in government revenue, by export pessimism, and by differential treatment of developing countries under GATT.Protection against imports is a burden on the export sector. Trade liberalization has important effects on economic growth and factor productivity. Recent programs of trade liberalization are implemented together with complementary macroeconomic policies to enhance the possibility of sustaining trade policy reforms to be sustained.     

On Export Composition and Growth

The hypothesis that exports in technology-intensive industries have a higher potential for positive externalities coupled with higher productivity levels (due to higher rates of capitalization) is tested using a comprehensive and detailed data set, covering 45 industrialized and developing countries and including exports of 33 industries over the time period 1981–1997. The estimation results, using a random effects model and employing an instrumental variables estimator, support the hypothesis of qualitative differences between high- and low-tech exports with respect to output growth. The superior performance of high-tech exports stems from their positive productivity differential to the domestic sector, while the externality effect is not significant at any meaningful level of significance. The positive productivity differential is only significant for the subsample of developing countries. No significant effects were found to be present in the subsample of OECD member countries.

Nexus between export,productivity, and competitiveness in the Indian manufacturing sector

This article assesses the nexus between export, productivity, and competitiveness in the Indian manufacturing sector. To do this, we examine the “learning by exporting” and “self-selection” hypotheses using firm-level data relating to Indian manufacturing firms relating to period from 1994 to 2017. The empirical analysis supports the “learning by exporting” hypothesis, but does not support the “self-selection” hypothesis. We also investigate the impact of export on competitiveness, and the results indicate a positive relationship. These findings remain consistent when we segregate manufacturing firms based on industries, intensity use of labor and capital, and firm ownership. In the light of these findings, we recommend that policy focus on enhancing the export capacity of manufacturing firms to further strengthen the competitiveness of Indian manufacturing.     

Understanding Cross-Country Differences in Exporter Premia: Comparable Evidence for 14 Countries

We use comparable micro level panel data for 14 countries and a set of identically specified empirical models to investigate the relationship between exports and productivity. Our overall results are in line with the big picture that is by now familiar from the literature: exporters are more productive than non-exporters when observed and unobserved heterogeneity is controlled for, and these exporter productivity premia tend to increase with the share of exports in total sales; there is evidence in favour of self-selection of more productive firms into export markets, but nearly no evidence in favour of the learning-by-exporting hypothesis. We document that the exporter premia differ considerably across countries in identically specified empirical models. In a meta-analysis of our results we find, consistent with theoretical predictions, that productivity premia are larger in countries with lower export participation rates, with more restrictive trade policies, lower per capita GDP, less effective government and worse regulatory quality, and in countries exporting to relatively more distant markets.

Contribution of external aid agencies to the social sector: Lessons for South Africa

The contribution of a major aid agency, UNICEF, to the social sector in three African countries is reviewed and important lessons are drawn for developing the social sector in South Africa. UNICEF's commitment to children and women and its substantial development expertise bestow many advantages on developing bilateral relations with UNICEF. It is equally important to develop sound social policies and adequate community‐based programmes in which UNICEF's expertise and resources can be incorporated. Guidelines are formulated for reducing dependence and vulnerability to donor assistance in the social sector.     

Manufacturing productivity in China and India: The role of institutional changes

In this paper we undertake a comparative study of productivity in the manufacturing sector for China and India using data from survey of manufacturing industries for the two countries. We find that productivity of manufacturing industries in China relative to that in India improved substantially over the 1998–2003 period. Specifically, the average total factor productivity (TFP) growth for the manufacturing sector over this period was about 11% higher in China than in India. We document two substantial changes in government policies in China that were not witnessed in India. First, the late 1990s saw an enormous wave of ownership restructuring due to the formal endorsement of private property rights by the Chinese central government. Second, in 1997 a large scale labour retrenchment program was launched to address the long standing problem of labour redundancy in the public sector. Using data from the Chinese survey of manufacturing industries, we quantify the impact of these large scale institutional changes on TFP of Chinese manufacturing industries. We find that these policy changes can explain about 30% of the growth in TFP of manufacturing industries. Hence we conclude that these institutional changes in China can account for a significant part of the gains in productivity of manufacturing industries in China relative to that in India over the 1998–2003 period.     

The rise of the service sector in China

This paper analyzes the underlying mechanisms that explain the rise of the service sector in China. Along with China’s unprecedented growth, the rapid expansion of its service sector is one of the fastest among emerging countries. However, the literature has yet to offer a clear understanding of such expansion. We show that distribution services first grow with the manufacturing sector, followed by personal services as per capita income rises. Motivated by this growth pattern, this paper provides a theory that describes 1) the complementarity between distribution services and the manufacturing sector, and 2) the substitution between personal services and home production. Empirics show that the personal service sector is the key to account for the early and rapid rise of the service sector in China. Quantitatively, high productivity growth and high capital intensity in the personal service sector, and labor market frictions are the most important channels. By revealing the growth pattern of the service sector in the early stages of development, the paper thereby contributes to the growing literature on the rising importance of the service economy.     

Reforming Tanzania's tea sector: a story of success?

Tea, one of Tanzania's major export crops, contributes about $30 million to the country's export earnings and provides employment to some 50 000 families. Despite the sector's early success, nationalisation of two estates along with neglect of the smallholder sector made it clear that only broad-based policy reforms would revive the sector. Reforms in the tea sector started much earlier than reforms in other export crop sectors. Furthermore, they were undertaken, and hence owned, by the government and the industry. The reforms have been by and large successful. There has been considerable supply response, tea quality has improved, and the research system has been very successful in developing and disseminating useful research findings to both estates and smallholders. However, some issues must be addressed, namely excessive taxation, over-regulation, and the trade policy environment.     

融资约束、产品质量与出口目的地选择

文章将融资约束、产品质量引入异质性企业贸易模型,研究企业融资约束对其出口目的地选择的影响,并从产品质量的视角进行机制分析。理论模型推导得出企业生产率与其在低收入国家出口占比呈负相关关系,而融资约束的存在则强化了这种负相关关系。通过理论分析发现,生产率、融资约束对于企业最优产品质量选择的决策会产生相反的影响,在不同收入水平的国家对产品质量偏好不同的情况下,这种机制恰恰可能解释了企业出口目的地选择的差异。文章使用中国微观企业贸易数据,进行实证研究发现：融资约束与企业出口低收入国家贸易占比成正向关系,此外融资约束与生产率之间存在着调节效应,生产率的提高可以缓解企业由于受到融资约束带来的影响。     

Access to Finance,Financial Development and Firm Ability to Export: Experience from Asia–Pacific Countries

With particular reference to Asia–Pacific countries, the present study examines how access to finance and financial development affects firms’ ability to enter export markets. Using firm‐level data from the World Bank Enterprises Survey, we found that access to finance plays a significant role in improving firms’ ability to export. In addition, development of the financial sector fosters export market entry. Among the financial development indicators, reach of the banking sector variable is most prominent. The present study suggests that improvements in access to finance and financial development (increases in the reach of the banking sector) enable firms operating away from capital or major cities to enter export markets easily. The present study supports policy intervention to strengthen access to the financial sector, which would encourage firms to export, and to facilitate export market entry for remotely located firms.     

Firm Heterogeneity and Export Pricing in India

We examine export pricing by Indian manufacturing firms in the early 2000s using a unique data set that matches firm characteristics with product and destination‐level trade data. We find that, in contrast to China and other countries, firm productivity is negatively associated with export prices, and export prices are negatively associated with distance while positively associated with remoteness. Our conjecture is that Indian innovation costs, which are higher than China's, drive down the scope for quality differentiation causing a negative association between productivity and prices. To the best of our knowledge, this is the first empirical evidence consistent with heterogenous goods and short quality ladders, a theoretical possibility noted in the study by Antoniades (2012), an outcome that arises here because of domestic Indian economic and regulatory features.

文章基于贸易内生技术进步经济增长模型,实证研究了中国1994—2010年间出口贸易结构影响产业结构的机制,发现出口贸易部门对非贸易部门技术外溢的正外部性影响促进了中国经济与产业发展,但中国各出口贸易结构部门以及整体出口贸易部门的全要素生产率水平依然较低,并由此提出通过实施贸易商品结构战略化、贸易方式结构一般化、贸易主体结构民营化以及贸易区域结构多元化来加速产业结构升级。     

Does importing more inputs raise exports? Firm-level evidence from France

Does an increase in imported inputs raise exports? We provide empirical evidence on the direct and indirect channels via which importing more varieties of intermediate inputs increases export scope: (1) imported inputs may enhance productivity and thereby help the firm to overcome export fixed costs (the indirect productivity channel); (2) low-priced imported inputs may boost expected export revenue (the direct-cost channel); and (3) importing intermediate inputs may reduce export fixed costs by providing the quality/technology required in demanding export markets (the quality/technology channel). We use firm-level data on imports at the product (HS6) level provided by French Customs for the 1996–2005 period, and distinguish the origin of imported inputs (developing vs. developed countries) in order to disentangle the different productivity channels above. Regarding the indirect effect, imported inputs raise productivity, and thereby exports, both through greater complementarity of inputs and technology/quality transfer. Controlling for productivity, imports of intermediate inputs from developed and developing countries also have a direct impact on the number of exported varieties. Both quality/technology and price channels are at play. These findings are robust to specifications that explicitly deal with potential reverse causality between imported inputs and export scope.     

Trade policy uncertainty,development strategy,and export behavior: Evidence from listed industrial companies in China

On the basis of new structural economics theory and heterogeneity of firm viability, this study analyzes the effect of trade policy uncertainty on firm export behavior using panel data of Chinese listed companies in the industrial sector. Empirical results show that the high uncertainty of trade policy significantly inhibits the extensive and intensive margins of firm export, while heterogeneity effect occurs across firms with different levels of viability. The development strategy that violates comparative advantage strengthens the negative impact of trade policy uncertainty on firm export. Despite their correlation with viability, the type of ownership, total factor productivity, and long-term loan are not suitable proxies for firm viability. Under high uncertainty of trade policy, export market diversification can alleviate the restraining effect of development strategy on firm export, whereas firms in regions with high industrial-oriented development tend to be vulnerable to cost shocks, thus reducing export market diversification. Findings present important implications for emerging market countries to enact better international trade and economic policies.     

Explaining the size differences of exporter premia: theory and evidence

Two decades of research have established pronounced exporter productivity premia (EPP) and exporter size premia (ESP). Yet, we do not know why such exporter premia differ so widely in magnitude across countries or sectors? We take this question to the theory and to the data. We derive the sectoral EPP and ESP in a standard heterogeneous firms trade model and apply the insights from the model to guide our empirical investigation of detailed Danish firm-level data. We show that a significant share of the observed variation in EPP and ESP across sectors can be accounted for by sector differences in the underlying variation in productivity dispersion, variable trade costs, the ratio of fixed export costs to fixed costs of production, and the elasticity of demand.     

Losing Ground: Latin American Growth from 1955 to 1999

I evaluate Latin America's relative economic performance by combining the Solow growth coefficients from 22 rich countries and the actual factor accumulation in the region. I find that actual income growth was consistently below simulated growth for all of the countries in the sample, indicating that low productivity is likely behind slow gross domestic product growth in the region. The low productivity growth is partially explained by government consumption spending, ethnic diversity, autocracy, export composition, and educational quality.     

Externalities,Cross-Sectoral Spillovers and Productivity Growth

We provide an interpretation of the productivity dynamics in the manufacturing sector based on the idea of the thick market externality à la Diamond. An econometric model has been estimated which allows to disentangle the long run effects of these trading externalities from those of internal economies of scale and of aggregate industry-level economies. The results obtained—based on a cointegrated system of non-linear-error-correction equations—confirm the hypothesis that the trading externality matters. Moreover, our findings point out that the emphasis generally posited both on internal and external economies of scale is not justified.     

Exports, economic growth and the consolidation of peace in El Salvador

The pillars of inclusive growth in El Salvador have to be nontraditional export growth, investment, and government determination to reduce income inequality and poverty. This article analyzes the key obstacles to the development of a competitive and dynamic export sector: Dutch Disease driven by aid and remittances, a significant decline in real wages, and lack of productivity growth. Policies can and must focus on productivity growth rather than wage repression, in the pursuit of peace consolidation and long-term competitiveness.     

Determinants of energy use in the informal food sector

Although enterprises in the informal food sector require energy to transform, cook and process food, energy-use patterns in this sector are not well understood by policymakers and the local-level authorities who regulate their trading activities. This paper reviews relevant literature and presents empirical data collected in Rwanda, Senegal and South Africa on the use of traditional and modern energy sources by informal food sector operators. Our sample includes male- and female-operated enterprises in the urban centres of three African countries where the informal food sector is important, not only for providing the convenience of affordable and readily prepared meals, but also as a source of income for women and men in developing countries. Multiple fuel-use and energy-stacking strategies are common among informal food enterprises and policy needs to acknowledge this if it is to intervene in ways that will benefit both enterprises and regulators.     

Brazilian public sector disequilibrium

The Brazilian public sector disequilibrium, as measured by growth in the global net public sector debt to GDP ratio, is examined with and without the Plano Cruzado. Two models are used, one based upon a discrete time framework and the other upon a continuous time framework, to trace paths of the debt to GDP ratio for the rest of the decade concentrating on the 1985–1986 period. Two major conclusions are reached. The first, of a theoretical nature, is that discrete time models are inappropriate in an inflationary context as they severely underestimate the inflation tax. This is evidenced by the fact that without the Plano Cruzado and an assumed inflation rate of 350%, the debt to GDP ratio grows from 1985 to 1986 in the discrete time model while it declines for this period in the continuous time model. The second is that the Plano Cruzado may put strong pressure on government finances in the near future due to the drastic fall in the inflation tax. In this case, both models show an acceleration in the growth of the debt to GDP ratio, the more drastic results appearing in the continuous model. This conclusion seems to hold true even if one allows the government to trade debt for monetary base with the consequent increase in money demand due to lower inflation, to roll over its internal debt at a lower average interest rate, or to roll over its foreign debt outstanding at a lower average interest rate.
