Gottfried Haberler's 1930 Reformulation of Comparative Advantage in Retrospect

In 1930 Gottfried Haberler freed the doctrine of comparative advantage from its association with David Ricardo's labor theory of value and provided us with its modern opportunity‐cost formulation. Haberler's reformulation of comparative advantage revolutionized the theory of international trade and laid the conceptual foundation of modern trade theory. On the occasion of its 75th anniversary, a symposium has been organized to reflect on and celebrate one of the most durable and fruitful ideas in the history of economic thought. In this introductory paper I revisit Haberler's original formulation, which was published in German in the Weltwirtschaftliches Archiv.     

The impacts of innovations and standards on trade of measurement and testing products: empirical results of Switzerland’s bilateral trade flows with Germany, France and the UK

Nowadays, the impact of the measurement and testing infrastructure on economic performance and trade is theoretically and even politically widely accepted. However, there are no empirical studies on this issue. The purpose of this paper is to elucidate the impact of innovative capacity and technical standards as one important part of the measurement and testing infrastructure on international trade flows and competitiveness. In order to focus on the direct causality between innovative technology and measurement and testing standards and the respective market, the empirical analysis concentrates on the trade of measurement and testing products of a country with a top position in measurement and testing technology. In its empirical analysis of Switzerland’s trade flows with Germany, France and the UK, the paper follows the approach of the pioneering paper of Swann et al. (Economic Journal 106 (1996) 1297), who integrated for the first time technical standards as a technology indicator in the estimation of UK trade performance. The trade flows in measurement and testing products from 1980 until 1995 are explained by both an indicator for innovative capacity and for the degree of standardisation. The first indicator is based on the patent applications at the European patent office. The latter uses the stocks of technical standards in the countries differentiated by their regional scope. Four different trade equations are analysed, besides an export and an import function, the trade balance and the intra-industry trade. The results clearly show that both Switzerland’s innovative capacity and its stocks of standards are able to explain its export performance in the three countries. Secondly, especially the stocks of international standards in Switzerland have a positive impact on imports into Switzerland from the three countries, confirming their positive role for fostering trade in general. Thirdly, Switzerland’s export surplus concerning the three trade partners is positively affected by the stocks of international standards in Switzerland, which seem to be an important factor for international competitiveness. Finally, the results of the intra-industry model underline the common view of the general trade-fostering effect of even national standards in the case of the trade with the three countries.     

Tear down this wall: on the persistence of borders in trade

Abstract Why do borders still matter for economic activity? The reunification of Germany in 1990 provides a unique natural experiment for examining the effect of political borders on trade. With the fall of the Berlin Wall and the rapid formation of a political and economic union, strong and strictly enforced administrative barriers to trade between East Germany and West Germany were eliminated completely within a very short period of time. Remarkable persistence in intra‐German trade patterns along the former East‐West border suggests that border effects are neither statistical artefacts nor driven by administrative barriers to trade, but arise from economic fundamentals.     

HOW DOES GLOBALIZATION AFFECT INDUSTRIAL COMPETITIVENESS?

Industrial competitiveness (IC), reflecting a country's ability to produce and export manufactures competitively, is closely associated with economic growth. How does globalization affect IC? While the topic is of great importance, empirical studies on the issue in the literature have been limited. This article attempts to close the gap by estimating the role of foreign direct investment (FDI) and international trade with cross‐country data in 1985 and 1998. Taking advantage of a recently constructed IC index, we estimate several regression models of effects of FDI and trade on industrial performance. Results suggest that FDI and trade have a positive impact on IC, and increasing integration with the world economy through FDI and trade contributes to better industrial performance.

Vertically Integrated North–South Trade and the Redux Model

The paper uses the framework of Obstfeld and Rogoff's Redux model to study the impact of monetary shocks on exchange rate, terms of trade, and welfare in the context of a North–South trade. The authors show that a relative Northern monetary expansion can depreciate or appreciate its currency depending on whether the consumption elasticity of money demand and the degree of monopolistic distortion are low or high enough. This shock has asymmetric effects on welfare in such a way that “beggar‐thyself” or “beggar‐thy‐neighbor” effects always occur.     

The incidence of,and returns to overeducation in the UK

Drawing on German data we look for evidence of a supply-side political business cycle. The hypothesis suggests that centralized trade unions with political interests and some degree of monopoly power may fine-tune their collective wage bargaining strategies so as to help preferred or to harm rejected parties in power. The regression results confirm that between 1960 and 1988 German trade unions exercised additional wage pressure before general elections under a Christian Democratic incumbent drew closer, trade unions pursued a restrictive wage policy to promote the government' chances for re-election.     

Institutional quality and the effectiveness of aid for trade

Trade policy barriers and high transaction costs hinder developing countries from taking the full advantages of the global trading system. In order to help developing countries overcome the problem, the World Trade Organization (WTO) launched the Aid for Trade (AFT) initiatives in its Ministerial Conference held in Hong Kong in 2005. We examine the effects of AFT inflows on bilateral trade costs facing 133 developing countries while accounting for differences in their location on the contours of various measures of institutional quality. Our results from the estimation of a mixed effects (random-intercept and random-coefficient) model indicate that institutional quality significantly affects the extent to which AFT reduces bilateral trade costs. An important policy implication of our findings is that an economically robust and sustainable reduction in bilateral trade costs facing developing countries requires the presence of both promulgated and effectively functioning institutions such as regulatory power and the rule of law.     

The Empirics of Comparative Advantage: Overcoming the Tyranny of Nonrefutability

I assess the empirical evidence on comparative advantage. I argue that the Heckscher–Ohlin–Vanek (HOV) relationship is not a refutable general‐equilibrium proposition. Consequently, the empirical Heckscher–Ohlin literature has been suffering from the tyranny of nonrefutability. The trade‐governing principle of comparative advantage, the Ricardo–Haberler–Deardorff (RHD) theorem, yields a refutable general‐equilibrium prediction about the pattern of international trade and allows for a theory‐based assessment of the magnitude of the gains from trade. The recent experimental evidence on Japan's nineteenth‐century opening‐up to world trade provides a strong case for the hypothesis that comparative advantage governed Japan's international trade in its early trading years. The aggregate gains from that trade are estimated to be no larger than 9% of Japan's GDP.     

Trade Effects of European Union Enlargement: an ex post model of trade between Spain and Latin America

Past research on European Union (EU) Enlargement has tended to neglect the effects on trade with non-preferred trading partners. This paper examines the consequences of EU enlargement on trade between Spain and the Latin American countries with which it has traditional economic and cultural ties. An import demand functions model was estimated for the period 1964–93. The country-level results showed that Spanish accession to the EU only had large adverse effects on its imports from Argentina. The results for non-agricultural products indicated a general absence of negative effects on Spanish imports. The aggregate results from the ex post model provide support for some, but not all, of the ex ante predictions of previous studies.     

Impact of China on trade in electronic products

Using 6-digit product-level data of exports in electronics, this paper finds robust evidence that China's exports adversely affect both the intensive export margin and the extensive export margin of its competitors for the 1992–2018 period. The displacement effects of China's exports on the intensive margin apply especially for the group of intermediate and capital electronic goods and are much more robust and significantly larger in magnitude than the displacement effects found in other studies using aggregated trade data. Finally, we find that China's displacement effect is increasing in China's advantage relative to its competitors in terms of human capital index and internet access of its population.     

Redistribution,trade and corruption: an empirical assessment

ABSTRACT

This article explores the role of institutional quality in the trade and inequality nexus. Does corruption shape the relationship between trade and inequality through its impact on redistribution? Our answer to this question builds on the hypothesis that trade raises inequality and that governments may want to intervene through appropriate redistribution schemes that aim at taxing the gains from trade in a way that offsets the negative effects of trade on inequality. Moreover, we argue that this mechanism may be distorted by corruption and bad institutions in general. Quite to the contrary to common wisdom, we find that trade reduces inequality in countries with high institutional standards by means of a low level of corruption but increases inequality in countries with low levels of institutional quality.     

What shapes player performance in soccer? Empirical findings from a panel analysis

In this article, we investigate the pay–performance relationship of soccer players using individual data from eight seasons of the German soccer league Bundesliga. We find a nonlinear pay–performance relationship, indicating that salary does indeed affect individual performance. The results further show that player performance is affected not only by absolute income level but also by relative income position. An additional analysis of the performance impact of team effects provides evidence of a direct impact of team-mate attributes on individual player performance.     

Russia's accession to the WTO: the potential for trade increase

This paper investigates the impact of institutions on trade and estimates the potential for trade increase between the Commonwealth of Independent States (CIS) and the European Union (EU). The latter is computed from a gravity equation using the procedure introduced by Hausman and Taylor [1981. Panel Data and Unobservable Individual Effects. Econometrica 49 (6) 1377–1398]. We find that CIS trade is still characterized by a large trade diversion effect, which implies that trade with non-CIS countries could increase considerably in the long run. Another source of deepening the level of the European trade integration comes from the convergence of institutions towards the EU standards in light of Russia's application to join the WTO.

促进抑或阻碍 ——技术标准影响国际贸易的理论机制及实证分析

本文主要研究了技术标准贸易效应的理论机制。基于12个国家1994—2011年的国别面板数据的估计结果显示,在一定程度上,技术标准对于进口和出口都有促进作用,但是,技术标准和进出口之间的关系总体上呈现出倒U型的特征;人口规模和贸易规模正相关,实际有效汇率和出口负相关,而与进口正相关;贸易伙伴国GDP的增加会促进出口,本国GDP和进口正相关;技术创新和外商直接投资对于进出口贸易都有显著的促进作用。     

Explaining Export Performance through Inputs: Evidence from Aggregated Cross‐country Firm‐level Data

Which trade barrier related to intermediate inputs forms a greater burden on the export performance of firms in developing countries? Using aggregated cross‐country firm‐level data covering 43 mostly developing economies, this paper estimates the marginal importance of the impact of various intermediate input trade cost barriers, namely tariffs, non‐tariff barriers (NTBs) and services barriers, on firms' export behavior. In a cross‐sectoral setting, this paper takes the firm's export performance in goods as a central focus to study the effects of these different trade barriers through the exporting firm's choice of use of intermediate inputs. The results show that the most significant trade barriers on inputs that impede export performance in developing countries are mainly NTBs and restrictions of services.     

Economic Performance, Trade Restrictiveness, and Efficiency

The paper addresses the question of whether trade restrictiveness impacts economic performance, via a trade restrictiveness index that is decomposable into a trade distortion and a domestic distortion component. The paper builds on the Anderson and Neary price index measure of trade distortion, in evaluating trade restrictiveness via a distance function approach. This is accomplished by adding a “dual” version to their trade restrictiveness price index, based on distance functions that scale output quantities. The authors compute the trade restrictiveness quantity index (TRQI) using a parametric frontier approach to model the production side of the economy, and a panel of information on the agricultural sector of a set of European Community countries. The results suggest that the use of TRQI makes a considerable difference to interpretations of the efficiency impact of agricultural trade policies in EC countries, as compared to policy‐oriented aggregates or result‐oriented measures of trade restrictiveness.     

Oman's trade and opportunities of integration with the Asian economies

This paper investigates the determinants of trade between Oman and its major Asian trading partners in order to gauge the impact of the process of trade liberalisation. The empirical findings based on the gravity model indicate that Oman's imports from Asia are strongly determined by Asian population, Asian per capita gross domestic product (GDP), real exchange rates, distance and Oman's per capita GDP. The results also provide strong evidence that Oman's oil exports to Asia are strongly and equally determined by Asia's and Oman's population. Our findings reveal that while distance is not a friction to Oman's oil exports, it has a weak regressive effect on non-oil exports. Our results also indicate a negative but statistically insignificant effect of trade liberalisation on non-oil exports. These findings certainly have policy implications in terms of Oman–Asia trade relationship and in particular the need for more policy intervention to liberalise the non-oil exports sector so as to facilitate its wider integration within Asia.     

Market Structure and the Environmental Implications of Trade Liberalization: Russia's Accession to the World Trade Organization

We investigate the environmental impacts of Russia's World Trade Organization (WTO) accession with a computable general equilibrium model incorporating imperfectly competitive firms, foreign direct investment and endogenous productivity. WTO accession increases CO₂ emissions through technique (?), composition (+) and scale (+) effects. We consider three complementary policies to limit CO₂ emissions: cap and trade, emission intensity standards and energy efficiency standards. With imperfectly competitive firms, gains from WTO accession result with any of these policies. If we assume perfectly competitive market structures, the negative environmental impacts of WTO accession are smaller and no net gains arise when environmental regulation involves energy intensity or efficiency standards.     

Knowledge of expansion on the geopolitics of Karl Haushofer

The article deals with the intellectual history, as well as the political impact, of Karl Haushofer's concept and notion of geopolitics. It attempts to contextualise his thinking and actions in the period between the two world wars as well as during the Nazi period. Haushofer's geopolitics is perceived as a quasimaterialist ideology, which was politically directed against the stipulations of the Versailles peace treaty, but can also be interpreted as a concept with a specific German and continental ideology which opposed the abstract forms of social intercourse common to maritime and naval cultures, based on trade and exchange, as represented historically by Britain and, later, the United States. The cultural, societal and political contrast between cultures of the land and cultures of the sea are seen as one fundamental presupposition in Haushofer's thinking. The article deals with the body of knowledge he developed, his personal history under Nazism, and the impact of his thought on German territorial revisionism in the 1920s.     

Exchange rate volatility and export growth in Nigeria

This article examines the impact of exchange rate volatility on Nigeria's exports to its most important trading-partner–the United States over the quarterly period January 1980 to April 2001. Using cointegration and vector error correction (VECM) framework, empirical tests indicate the presence of a unique cointegrating vector linking real exports, real foreign income, relative export prices and real exchange rate volatility in the long run. Furthermore, the results show that increases in the volatility of the real exchange rate raise uncertainty about profits to be made which exert significant negative effects on exports both in the short- and long-run. Our results also show that improvements in the terms of trade (represented by declines in the real exchange rate) and real foreign income exert positive effects on export activity. Most importantly, we found that the trade liberalization and economic reform policies implemented in the post-1986 structural adjustment period contributed to Nigeria's export performance. Overall, our findings suggest that Nigeria's exporting activities can be further boosted by policies aimed at achieving and maintaining a stable competitive real exchange rate.
