Comparing tests of the theory of exhaustible resources

The empirical relevance of Hotelling’s exhaustible resource theory has been tested with primarily negative results. Tests have been performed on various resources, at different levels of aggregation, with varying market structures, and over different time periods. Consequently, it is difficult to draw any general conclusions concerning the theory’s applicability in explaining producer behavior, given the assumptions and restrictions implicit in the data and tests. This paper compares test results when the implicit restrictions associated with the data are removed. Employing a single data set we compare the results for four published tests. Even with this uniform data set, two approaches reject the theory while two do not.     

Constant per capita consumption paths with exhaustible resources and decaying produced capital

We introduce decay in produced capital and exogenous technical progress to the recent “Solow Model” of Asheim et al. with population growth and observe the possible collapse of the economy given too high a rate of decay. “Enough” technical progress can restore sustainable per capita consumption.     

Effective demand and the terms of trade in a dual economy: a Kaldorian perspective

Along the line suggested by Nicholas Kaldor, the paper incorporatesinto the analysis of a dual economy effective demand as a problemof generation of agricultural surplus and its realisation intopurchasing power for industrial goods. Through this approach,it is shown how one obtains empirical predictions about unevensectoral growth rates, as well as an effect of the movementin the terms of trade on long-term industrial growth which iscontrary to that suggested by Lewis. The paper also specifiesthe process of dynamic adjustment of industrial growth in aself-reinforcing circular flow under conditions of sufficientlyhigh agricultural growth, extending the effective demand argumentin a dual economy.     

Modelling information and hedging: The exporting firm

The paper examines the economic role of modelling information on the decision problem of an exporting firm under exchange rate risk and hedging. Information is described in terms of market transparency, i.e., a publicly observable signal conveys more information about the random foreign exchange rate. We analyze the interaction between market transparency and the ex ante expected utility of the exporting firm. It is shown that more transparency on the foreign exchange market may result in higher or lower export production.     

Environmental regulation and trade pattern：a case of China

As a growing number of countries, including both developed and developing countries, have in recent yearstaken environmental regulation at different levels, a question of great concern has been raised： can the regulation alterthe existing trade volume and trade pattern, and ultimately drive pollution-intensive industries to countries with low-levelregulations or even those without regulations at all？ Starting from the three different propositions concerning therelationship between environmental regulation and trade pattern, this paper applies cointegration analysis and errorcorrection model to empirically testing the relationship between environmental regulation and trade in China during theperiod of 1985-2005. Our empirical results indicate that in the short run the collection of pollution discharge fees bearsa positive impact on the export share of clean products of total exports. Thus, higher pollution discharge fees raise theratio of clean products exports to total exports. This further indicates that more stringent environmental regulationpromotes the exports of clean products. In the long run pollution discharge fees are positively correlated with the exportshare of clean products but negatively associated with their import share. Such correlations imply that environmentalregulation tends to facilitate the international specialization in line with comparative advantages.     

Exhaustible resources and secondary materials: A macroeconomic analysis

In this paper we have developed an endogenous growth model to deal with exhaustible resources and secondary materials together, under the assumptions that these two inputs are, or are not, technologically perfect substitutes of each other, in order to compare the results obtained under both hypotheses. We highlight the implication of these two assumptions on the rate of growth of total output and upon the flow of exhaustible resources extracted. There are also some other interesting findings related to the spill-over on welfare of the waste recycling process, and the dynamics of shadow prices of both inputs considered. Finally, some implications on Hotelling's rule also emerge in our analytical framework.     

New trade theory versus old trade policy: a continuing enigma

This paper examines the theoretical and empirical grounds fortrade liberalisation. We note that many of the conventionalarguments relating to the static and dynamic gains from liberalisationare based on fragile theoretical grounds. We also show that,although new trade theory takes account of some of the complexitiesof international trade and although the analytical thrust ofmany models justifies intervention, such policy conclusionsare rejected even by those at the forefront of these theorieson the grounds of political economy arguments which do not standup to careful scrutiny. Finally, we show that arguments favouringtrade liberalisation are not supported by existing empiricalresearch, which generally fails to capture the complex and ambiguouseffects of liberalisation and openness.     

Exchange rate changes and endogenous terms of trade effects in a small open economy

This paper shows that the small-country assumption of dependent-economy models is unlikely to hold for many of the cases in which this class of models is used, for example, in the analysis of a terms of trade shock in the “commodity currency” models. When a shock affects most or all of the small countries exporting a commodity, the combined exchange rate effects will result in endogenous terms of trade changes even for those countries too small to individually affect world markets. The paper also explores the possible implications of these secondary terms of trade changes for the dependent-economy models.     

The core periphery model with asymmetric inter-regional and intra-regional trade costs

We generalize the model of Krugman (J Polit Econ 99(3):483–499, 1991) to allow for asymmetric trade costs between regions and for (asymmetric) trade costs that are internal to the regions. We find that industrial activity, in a region, is enhanced by higher costs of importing and lower costs of exporting (more precisely, by a higher ratio between the two trade costs). This suggests that countries may impose tariffs on imported goods and seek to remove the import tariffs in other countries (unilateral protectionism) in order to foster industrial activity. Industrial activity is also promoted by lower domestic internal trade costs and higher foreign internal trade costs (more precisely, by a lower ratio between the two trade costs).     

The trade balance and the terms of trade in a two-country two-sector OLG economy

We consider a two-country, two-sector OLG model. It is shown that the trade balance and the relative price of exports are always positively related when exports are labor intensive regardless of the elasticity of intertemporal substitution in consumption. A large response of savings to future prices becomes a sufficient condition for an inverse relation between these variables only if exports are capital intensive. In this case, a rise in the terms of trade can be followed by a trade balance decline if consumption goods are capital intensive and the income effect implied on savings is negative and large.     

中印双边贸易的基础探析与前景展望

中国和印度被认为是21世纪世界上两个最大的和增长最快的经济实体。但是，受冷战的影响，长期以来，两个国家在经贸方面没有太多的合作。近年来，两国高层领导人开始了接触。政治合作导致了双方经济上的合作，双边贸易已成为经济合作的发动机。并且，当今中印的双边贸易不断增强的趋势正在对两国的政治交往产生积极影响。两国的边境贸易被定位为一种解决双方长期存在的政治问题的工具。我们不能忽略的一个事实是，印度是中国在南亚地区最大的贸易伙伴，中印的边界贸易对两国的政治关系和相互理解有明显的影响。中印双边贸易基础坚实、前景光明。     

Technical progress,population growth and intergenerational equity in a model with many exhaustible and renewable resources

A condition ensuring intergenerational equity is derived using a neoclassical model of many exhaustible and renewable resources involving technical progress and population growth.     

The 'paradox' of F. Graham (1890-1949): a study in the theory of international trade

The aim of this paper is to investigate the origins of the protection argument based on increasing and decreasing returns to scale. The development of this theoretical framework is outlined in order to argue that F. Graham's demonstration consists of a synthesis of previous work. We then discuss the debate that took place in the 1930s, which ended with the rejection of Graham's argument as being a paradox or a theoretical curiosity.     

Economies of scale and trade policy: The median voter model revisited

Why do some political economy models perform so poorly in predicting actual trade policy? Do scale economies provide the missing puzzle to our understanding of the anti-trade bias? By integrating economies of scale in production, this paper theoretically reinstates the median voter model as in Mayer [Mayer, W. (1984). Endogenous tariff formation. The American Economic Review, 74, 970–985] as a suitable political economy model in predicting trade policy. The modified model generates the scope for the anti-trade bias and predicts that sometimes economic, rather than political, considerations may lead to restrictive trade.     

The impact of the Soviet trade shock on central and East European economies

The paper examines the significance of what is called the Soviet trade shock on central and East European economies. The analysis involves two steps: first, the terms-of-trade effect of replacing the CMEA trading rules by market rules is estimated, and second, the impact of the loss of export markets in the former Soviet Union is assessed. The results of estimating the terms-of-trade effect for Hungary and Poland show that the income losses in 1990–1991 have not been as substantial as commonly believed (3.5 percent of GDP and 1.0 percent of GDP, respectively). The decomposition of the fall of total Soviet imports in 1991 into three categories, reflecting the impact of domestic recession, reduction of trade with ex-CMEA, and diversion of imports from ex-CMEA to western countries allowed us to estimate the CMEA-induced part of the trade collapse at 36 to 49 percent of the total fall of exports to the Soviet Union by the CEECs (except Romania), with the impact of domestic recession being in all cases stronger than the CMEA dissolution effect. An attempt has also been made to estimate the impact of the Soviet trade shock on GDP levels in CEECs. The results obtained indicate that the collapse of exports to the Soviet Union in 1991 may have been responsible for about one third of the officially reported GDP fall in Czechoslovakia and Poland, and for more than half of the GDP fall in Bulgaria and Hungary, but the impact of the CMEA-induced export fall was much smaller. The impact of the Soviet trade shock on Romania was negligible. The results obtained suggest a smaller impact of the Soviet trade shock on Hungary and Poland, as compared with some other studies. The conclusions should, however, be treated with caution, because of many untested assumptions underlying the analysis.I would like to acknowledge helpful comments received on earlier drafts of the paper by Daniel Gross, Dieter Hesse, Gabor Oblath, and Mica Panic. The views expressed in the paper are, however, my own responsibility.     

Optimal combination of pollution prevention and abatement policies: The case of agricultural drainage

The adoption of pollution prevention and abatement practices is examined in the context of a model of exhaustible resource use with a backstop technology. For the sake of concreteness, the paper focuses on the problem of water-logging caused by the subsurface accumulation of agricultural drainwater. In modelling this problem, a region's underground capacity to store drainwater is considered an exhaustible resource, while the installation of subsurface drainage is viewed as the corresponding backstop technology (or abatement practice). The exhaustible resource is typically over-exploited due to common access problems, which forces a suboptimally fast adoption of the abatement practice. Conservationist irrigation technologies, such as drip and sprinkler systems, tend to reduce drainwater generation, and their adoption could increase social welfare by delaying the abatement stage. Public policies are suggested to increase the adoption of such conservationist technologies. Data from California is used to illustrate the results and to demonstrate the efficacy of the model for policy purposes. While the setting used for the analysis in this paper is quite specific (i.e., water-logging), the same general modelling ideas may be applied to many other problems of environmental degradation.     

Tariffs,trade and unemployment in a disequilibrium model: issues and policies

This paper studies the disequilibrium transition process engaged by increased openness to trade, and the effect of institutions, market behaviors and economic policies on that transition. The issue is analyzed with a simple two country (north and south), two goods model, amended in order to take into account the time dimension of both the production and the decision processes. Investigating the consequences of a tariff decrease by means of numerical simulations, we show to what extent wage and price setting, and the degree of tightness of monetary policy affect the outcome of the disequilibrium process. The main result is that capturing the gains associated with international trade requires market behaviors and economic policies, which are rather different from what is usually prescribed.

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.     

International trade and renewable resources under asymmetries of resource abundance and resource management

This paper examines the interaction between relative resource abundance and resource management regimes in determining trade patterns and gains from trade in a two-country model with a renewable resource. A model developed by Brander and Taylor [Brander JA, Taylor MS (1997b) Resour Energy Econ 19:267–297] is extended. It is shown that relative resource abundance determines trade patterns if resource abundance is similar in both countries and the relative demand for the resource good is moderate, or if resource abundance is sufficiently different and the relative demand is not so high. Otherwise, a difference in resource management regimes determines trade patterns. Even under an open-access regime, the resource-scarce country gains from trade unless resource abundance is similar and the relative demand is low.      

The choice of trade regime: delayed reform under productivity fluctuations and cost of structural change

Despite the advantages of international trade, a number of countries have stuck to restricted trade regimes, allowing the productivity gap between themselves and the “trading” world to become huge before turning to a more outward oriented trade policy. As a supplement to the existing explanations for the hesitation to change trade regime, we present a model where the international productivity development shared by open economies, is uncertain. Due to uncertainty, it might be optimal to wait and maybe exercise the option to change trade regime later, i.e. to delay a trade reform.
