The paper investigates the relative importance of trade policy and ‘natural’ sources of export taxation in Malawi, a landlocked African economy. These sources of export taxation are in turn used to explore how export supply would respond to trade liberalisation as opposed to measures which lower other international trade costs. The findings indicate that trade policy barriers are now only a limited source of ‘true’ export taxation and that trade policy reform needs to be complemented with reforms to reduce international trade, including transport, costs.  相似文献

I extend the North–South product cycle model of Grossman and Helpman [Grossman, G. and Helpman, E. (1991b), “Endogenous Product Cycles,” Economic Journal, 101, 1214–1229.] to a three-region model where the region Middle undertakes both innovating and imitating activities in a trading equilibrium. In contrast to Grossman and Helpman [Grossman, G. and Helpman, E. (1991b), “Endogenous Product Cycles,” Economic Journal, 101, 1214–1229.], I find that an expansion in the North's labor force or a rise in the productivity of the North's labor in the research sector incurs no effect on the rate of the South's imitation. Moreover, the long-run relative wage of a region can vary inversely with the size of that region.  相似文献

Brander and Krugman (1983) and Sertel (1988) followed by Krugman (1989), showed two sides of a ‘trade paradox’: The paradox in competition, viz. that opening trade (or increasing competition) may cause welfare to decline, and the paradox in efficiency, viz. that an increase in unit transport cost may increase welfare. In this paper, we consider the situation in an environment where interventionist trade policies are not permitted but each country is sovereign to impose an excise tax (or subsidy). The paradoxes persist under equilibrium excise taxes, reckoned both at the non-cooperative (Nash or dominant strategy) equilibrium and at the cooperative solution among tax-imposing authorities maximizing welfare. We also see that the paradoxes persist in a taxless environment where market equilibrium is Stackelberg rather than Cournot.  相似文献

This paper investigates how variations in endowments and the structure of preferences impact on the coalition formation decisions of asymmetric countries. There exist relatively few general results on the relationship between country characteristics and trade bloc formation. Here, new light is shed on this issue by systematically simulating bloc formation and by explicitly analysing the blocking behaviour of coalitions. A general equilibrium model of world trade is implemented with equilibrium coalition formation being modelled using the equilibrium concept of the core. It is found that global free trade is observed when all countries are similar. Customs unions tend to form between countries with ‘adjacent’ consumer preferences or with ‘adjacent’ endowments of their export commodity. Finally, in contrast to the existing literature but consistent with observed behaviour, it is found that free trade areas often Pareto dominate customs unions, provided consumer preferences differ sufficiently.  相似文献

Studies, which have discussed some of the important issues concerning the measurement of trade costs, have conceded that the literature is still in the early stages of understanding and measuring what the real costs are. It is in this context, decomposing trade costs into ‘natural’ costs, ‘behind the border’ costs, ‘explicit beyond the border’ costs, and ‘implicit beyond the border’ costs, this paper suggests a method to measure the impacts of these components on changes in exports between countries in the absence of complete information on all the components of trade costs in home and partner countries. Empirical measurement has been demonstrated using 1999 and 2004 trade data from Pakistan. The results show that Pakistan's export growth between 1999 and 2004 came mainly from the reduction in both ‘explicit and implicit beyond the border’ trade costs in partner countries.  相似文献

We explore the impact of labour turnover on firm performance by analysing the predictions of an extension of the efficiency wage model of [Salop, S., (1979) ‘A Model of the Natural Rate of Unemployment’, American Economic Review, 69, 117–125.] developed by [Garino, G. and Martin, C., (2008) ‘The Impact of Labour Turnover: Theory and Evidence from UK Micro Data’, Quantitative and Qualitative Analysis in the Social Sciences, 1(3), 81–104.], which separates incumbent and newly hired workers in the production function. Within this theoretical framework, an exogenous increase in the turnover rate can increase profits if firms do not choose wages unilaterally. We test the theoretical predictions of the model using UK cross-section establishment-level data, the 2004 Workplace and Employee Relations Survey. In accordance with our theoretical priors, the empirical results support the standard inverse relationship between the quit rate and firm performance where firms unilaterally choose the wage and generally support a positive relationship between firm performance and the quit rate where trade unions influence wage setting.  相似文献

Helpman and Krugman (Market structure and foreign trade. Increasing returns, imperfect competition, and the international economy. MIT Press, Cambridge, 1985) provide a synthesis of the traditional factor proportions theory of international trade and the theory of international trade due to the exploitation of scale economies in imperfectly competitive markets. They derive illuminating results about trade patterns and gains from trade, among other things, leaving unanswered the question of existence of equilibrium, however. The central significance of their characterization of properties of free trade equilibria with inter-industry and intra-industry trade calls for an analysis of existence of equilibrium. This is the object of the present paper. We prove the existence of equilibrium for the integrated multi-sector multi-factor Helpman–Krugman economy without national borders. Well-known conditions ensure that the world economy under free trade reproduces this equilibrium and thus establishes existence of a free trade equilibrium. Since an equilibrium of the integrated economy is not necessarily unique, the same holds true for a free trade equilibrium.  相似文献

It has become common to measure the quality of exports using their unit export value (UEV). Applications of this method include studies of intra-industry trade (IIT) and analyses of industrial ‘competitiveness.’ This literature seems to assume that export quality and export price (the most natural interpretation of UEV) are not merely correlated but that they follow each other one-for-one. We put this assumption under scrutiny from both a theoretical and empirical point of view. In terms of theory, we formalize this assumption as a hypothesis of the proportionality of equilibrium prices and equilibrium qualities. We discuss several cases for which this hypothesis is theoretically doubtful (nonlinear utility and cost functions; strong and asymmetric horizontal product differentiation). We also suggest a method of verifying the hypothesis for cases in which it cannot be easily rejected theoretically. This method is then applied to German imports in the period of 1994–2009. We find that the implications of the proportionality hypothesis are largely contradicted by the data.  相似文献

In this paper, the economic theory of index numbers is applied to the construction of industry-level export price indices and export quality indices. These indices are used to make consistent comparisons of export prices and qualities at the same or different points in time. Evidence of quality change over time was found to be an important phenomenon in explaining the variation of unit value indices over time and across countries for some European Union trade flows. About half of the unit value differences among destination countries can be explained by quality differentials. The quality-corrected price indices are potentially useful in any empirical application in which accurate measures of export prices are needed.The authors wish to thank Bienvenido S.

This paper studies how the effect of trade openness on economic growth may depend on complementary reforms that help a country take advantage of international competition. This issue is illustrated with a simple Harris–Todaro model where welfare gains after trade openness depend on the degree of labor market flexibility. The paper then presents cross-country, panel-data evidence on how the growth effect of openness may depend on a variety of structural characteristics. For this purpose, the empirical section uses a non-linear growth regression specification that interacts a proxy of trade openness with proxies of educational investment, financial depth, inflation stabilization, public infrastructure, governance, labor market flexibility, ease of firm entry, and ease of firm exit. The paper concludes that the growth effects of openness may be significantly improved if certain complementary reforms are undertaken.  相似文献

This paper studies a model of buyer investment and its effect on the variety and vertical structure of international trade. A distinction is made between two types of buyer investment: “Flexible” and “specific”, which differ in the ability of a buyer to match with a seller. The interaction of buyer investment with the entry and pricing incentives of suppliers are analyzed. It is shown that (i) there can be multiple equilibria in the variety of products traded, and (ii) less product variety is associated with more intrafirm trade. The possibility of multiple equilibria is consistent with the observation that some similar economies, such as Taiwan and South Korea, differ substantially in their export varieties to the U.S. A cross-country empirical analysis confirms the negative correlation between export variety and intrafirm trade.  相似文献

According to conventional home market effects, free trade tends to shrink the market share for a smaller economy in differentiated manufacturing goods, and in the extreme, leads to a complete hollowing out of the industry. Departing from the original Helpman–Krugman modelling assumptions behind the home market effects, we introduce a technology advantage in terms of the difference in fixed cost and/or marginal cost between trading partners and prove that home market effects will be offset and even reverse if a small economy has better technology than another country. With a higher elasticity of substitution, the marginal cost advantage becomes more important if it is to dominate the home market effect. We also show that even with an identical country size, the intra‐industry trade addressed in the existing literature may not occur; it will occur only if the technology differential lies within a certain range that is positively affected by the level of transport cost.  相似文献

This paper studies the nonlinear adjustment between industrial production and carbon prices – coined as ‘the carbon-macroeconomy relationship’ – in the EU 27. We model carbon price returns and industrial production as nonlinear and state-dependent, with dynamics depending on the sign and magnitude of past realization of returns and the growth of industrial production. Our findings show that (i) macroeconomic activity is likely to affect carbon prices with a lag, due to the specific institutional constraints of this environmental market; (ii) the joint dynamics of industrial production and carbon prices seem adequately captured by two-regime threshold vector error-correction and two-regime Markov-switching VAR models compared to linear models as main competitors. The regime-switching models proposed are profoundly checked for their economic content and statistical congruency, and are found to provide a sound statistical framework for a comprehensive analysis of the carbon-macroeconomy relationship.  相似文献

Motivated by growth models based on the variety of capital goods, recent empirical studies have established links between productivity and several trade-based measures of product variety, carrying the implication that these measures may represent technology. We study this implication by explicitly proposing the variety of capital goods available for production as a direct measure of the state of technology. Within a simple growth and development framework, we derive a ‘conditional technological convergence’ hypothesis on how this variety should behave if it were indeed to represent the state of technology. The hypothesis is tested with highly disaggregated trade data, using tools from the income convergence literature. The results suggest that a trade-based count measure of the variety of available capital goods, allowing for product differentiation by country of origin, indeed behaves ‘as if’ it represented technology when change of technology is understood as a learning process, and that there is conditional technological convergence among our panel of mainly OECD and transition economies.  相似文献

External wealth, the trade balance, and the real exchange rate   总被引:1,自引:0,他引:1  
We examine the link between the net foreign asset position, the trade balance and the real exchange rate. In particular, we decompose the impact of a country's net foreign asset position (‘external wealth’) on its long-run real exchange rate into two mechanisms: the relation between external wealth and the trade balance; and, holding fixed other determinants, a negative relation between the trade balance and the real exchange rate. We also provide additional evidence that the relative price of nontradables is an important channel linking the trade balance and the real exchange rate.  相似文献

This study uses a global model of the forest sector to examine changes in log production, consumption, prices, and trade and discusses the impacts of changes on economic wealth transfers for log export ban and log export tax scenarios. The results indicate that trade barriers are inefficient in allocating logs to domestic processors when a supply shortage exists. The trade barrier produces economic losses that exceed the benefits to the processors. A log export ban reduces log prices in the Pacc North-west by 8.5% and reduces timber harvests by 6.7%. The logs diverted to domestic mills save 1,208 more jobs than log export job losses but at an average annual cost of £230,463 per job saved. Economic transfers benefit lumber producers in the region under the ban. However, the benefits amount to 61% of regional timber producer losses including losses in the log export price premium, 39% of the loss to Asian processors, and 55% of the global consumer losses. Globally, lumber consumers lose £733 million. A log export tax scenario produces smaller impacts on prices and harvests since it does not eliminate total log exports. The tax scenario saves no jobs, and the average economic gain per job lost is £24,251 or about two-thirds of the current average salary in the forest products sector in the region. A log tax has the ability to retain £78 million in tax revenues.  相似文献

This paper examines empirically how exogenous changes in the terms of trade affect the real exchange rate through the relative price of traded goods with Canada–US data. The relative price of traded goods is constructed using prices at the dock and retail prices. The first measure emphasizes the importance of home bias in consumption of traded goods. The second measure highlights the importance of distribution services required for consumption of traded goods. It is found that terms of trade shocks affect the relative price of traded goods using both measures. A possible interpretation of empirical findings is that home bias and distribution services are important for understanding the relative price of traded goods.  相似文献

This paper examines the effects of conversion of one type of physical trade restrictions into another on the intra-country wage inequality in a standard 2 × 2 × 2 Heckscher–Ohlin–Samuelson model. It shows that a conversion of an import-quota into an equivalent voluntary export restraint raises wage-inequality in the country importing the unskilled-labor intensive good and lowers the wage-inequality in its trading partner. This result does not depend on whether the unskilled-labor intensive good or the skilled-labor intensive good was initially subject to an import quota. Conversion of the import-quota into an equivalent import tariff, on the other hand, may lead to a rise in wage inequality in both countries. The driving force behind these results is the real income effect that conversion of one type trade restriction instrument into another results in.  相似文献

Agglomeration, integration and tax harmonisation   总被引:1,自引:0,他引:1  
Consideration of agglomeration reverses standard theoretical propositions in international tax competition. We show greater economic integration may lead to a ‘race to the top’ rather than a race to the bottom. Also, ‘split the difference’ tax harmonisation may harm both nations, a result that may explain why real-world tax harmonisation is rare. The key is that industrial concentration creates ‘agglomeration rent.’ The ‘core’ region can thus charge a higher tax rate without losing capital. The size of such rent is a bell-shaped function of the level of integration, so the tax gap first widens before narrowing as integration increases.  相似文献
