This paper uses a two-equation dynamic simultaneous equation model that accounts for call externality and arbitrage, and a dynamic panel estimator to investigate the demand for international telephone calls between the US and African countries. Using panel data from 45 African countries over the 1992–1996 period, we find that the demand for telephone calls from African countries to the US is price elastic while the demand for telephone calls from the US to African countries is price inelastic. We find telephone calls originating from African countries to the US are complementary to calls from the US to African countries while calls originating in the US to African countries are substitutes for calls to the US that originate in African countries, and calls between the two sets of countries exhibit reciprocal and arbitrage effects. We also find that the demand for telephone calls between the US and African countries show strong dynamic effects. Finally, we find that telephone demand between African countries and the US responds positively to income and trade. Our results have interesting research and policy implications.  相似文献

Although the number of regional trade arrangements (RTAs) among the lowest-income developing countries is surging, the literature on their welfare effects is still scarce, and the few that exist fail to provide conclusive results. Furthermore, these RTAs are dominated by countries with a small share of total exports destined for intraregional trade flows. Our study focuses on the welfare effects of RTAs (pertaining to trade creation and trade diversion) among this group of countries. We use a theoretically justified gravity model to estimate welfare effects, focusing on trade creation and trade diversion and deviating from the norm in related studies, accounting for heterogeneity in third countries. Using ECOWAS as a sample, we estimate welfare effects on 1992–2012 annual bilateral imports for 14 countries from 169 countries. Contrary to conventional expectations in the literature, we find that economic integration among small and relatively low-income countries that have a small share of total trade with each other is welfare-improving for the members as a group, for the majority of the individual member countries, and for some third countries. Accounting for heterogeneity in third countries reveals that an RTA among low-income countries has a particularly robust trade-creation effect.  相似文献

Over the last decades, developed countries have provided developing countries with preferential market access via trade policies in the form of nonreciprocal preferential trade agreements (NRPTAs). Despite the lack of reciprocity of this kind of agreements, certain criteria for designating eligible countries refer to the commercial interests of benefactor countries. This paper examines for the first time the effect of NRPTAs on benefactors’ exports to beneficiary countries. Using recent developments in the econometric analysis of the gravity equation, we find robust evidence that nonreciprocal agreements have had an economically significant effect on exports not only for beneficiary countries but also for benefactor countries.  相似文献

ABSTRACT

This paper uses the Consensus Economic Forecast poll to investigate how forecasters in the foreign exchange market form expectations and whether the expectation formation process differs between industrialized and emerging countries. In order to explain the expectation formation of forecasters in countries and country groups, we analyze around 50,000 forecasts for 22 OECD member currencies. We find that differences between the way forecasters in industrialized countries and emerging countries form exchange rate expectations. However, we show that one important difference is due to a difference in forecasting behavior of emerging countries. Controlling for this feature lets the forecasting behavior in emerging countries resemble more the ones found for industrialized countries, but not for all forecast horizons.  相似文献

This paper investigates the relationship between investment and savings in 26 OECD countries and demonstrates that the relationship changes when the countries under consideration in the selected panel vary. Accordingly, panel estimations using annual data for the period from 1970 to 2008 have been made for various groupings of developed countries, specifically the OECD as a whole, the EU15, NAFTA and the G7. Additionally, the paper examines changes in investment savings relationships when the presence of structural shifts in developed countries – where such exist – are taken into account. Recently developed panel techniques are employed to examine the investment savings relationship and estimate saving-retention coefficients. The empirical findings reveal that the Feldstein–Horioka puzzle exists only in the panel of G7 countries, wherein the saving-retention coefficient is estimated as 0.754 and 0.864 (for the full sample of G7 countries and for stable G7 countries, respectively). The estimated saving-retention coefficient for unstable G7 countries is 0.482, which indicates a higher level of capital mobility in unstable countries with respect to stable ones. This conclusion is further supported by the estimations for OECD countries and the EU15.  相似文献

The paper aims to define the optimal thresholds of publications and Research and Development (R&D) expenditure and to investigate their impacts on patenting in OECD and BRICS countries. To do so, we use a dataset of 25 countries divided into two country sub-samples for the period 1996–2013, employing the Panel Smooth Transition Regression (PSTR) model. The results indicate that the threshold of publications after which patenting activity is promoted is 8417 publications for the OECD countries and 20,848 for the BRICS countries, while the share of R&D in % of GDP should not exceed 1.683% for the OECD countries and 0.975% for the BRICS countries.  相似文献

Expenditures devoted to research and development (R&D) are scarce and thus need to be used as efficiently as possible given the financial constraints countries are facing. This article assesses the relative efficiency of R&D expenditures for 26 OECD member countries and two nonmember countries. As countries differ in their national innovation systems and states of economic development and industrialization, e.g. transition economies in Eastern Europe versus Asian countries versus Anglo-Saxon countries, the measurement of R&D efficiency needs to consider differences in the technology of knowledge production. By means of a latent class model for stochastic frontiers, we relax the assumption of a homogeneous technology frontier and model technological differences in knowledge production among countries. Empirical evidence suggests the existence of different classes stressing the importance of accounting for countries’ disparities within R&D efficiency analysis.  相似文献

This paper tests for heterogeneous effects of cognitive skills on economic growth across countries. Using a new extended dataset on cognitive skills and controlling for potential endogeneity, we find that the magnitude of the effect is about 60% higher for low-income countries compared to high-income countries, and it more than doubles when low TFP countries are compared to high TFP countries. There are also marked differences across geographic regions. Using data on the share of the population with advanced and minimum skill levels, our results also indicate that high-income countries should focus on increasing the number of high skilled human capital, while countries from Sub-Saharan Africa would benefit more by investing in the development of basic skills.  相似文献

This paper calculates Theil's entropy index to measure the extent of productivity differences across 92 countries for the period from 1970 to 2003. While there is evidence of increasing differences in productivity across these countries, we observe different patterns when we group the countries by income levels. These differences seem to be decreasing among middle income developing and developed countries, whereas they seem to be widening among low and high income developing countries. The results of our multivariate time series analysis also suggest that FDI increases productivity differences among low and high income developing countries, whereas GDI reduces these differences among low income countries in the long-run. Granger causality test results indicate that while an increase in GDI leads to a decline in growth of trade, a higher growth of trade appears to be important for attracting FDI to middle income countries. Furthermore, a reduction in productivity differences and a higher FDI growth lead to higher growth of trade in developed countries.  相似文献

This paper studies the responsiveness of government expenditures to business cycles and introduces an index of asymmetric government expenditures using panel data for advanced and developing countries during the period 1981–2014. The empirical findings show that government expenditures tend to be procyclical in developing countries but acyclical in advanced economies. In addition, it is found that government expenditures respond in a countercyclical manner during bad times in advanced countries, but in a strongly procyclical manner during good times in developing countries. The index of asymmetric government expenditures for developing countries tends to be higher than that of the advanced countries.  相似文献

This paper argues that globalization is a key factor in stimulating institutional reforms in developing countries that promote financial development and economic growth. Advanced countries can help in this process by supporting the opening of their markets to goods and services from emerging-market countries. By encouraging these countries to increase their participation in global markets, advanced countries can create exactly the right incentives for developing countries to implement the reforms that will enable them to have high economic growth.  相似文献

This paper seeks to shed light on possible changes in the government debt dynamics for the first 12 euro area countries. Structural breaks are present around the global financial crisis for most countries, but not for Germany and France, the two core countries in the euro area. The properties of the government debt dynamics differ markedly across the countries receiving bailouts.  相似文献

This paper tests the validity of the Fisher hypothesis, which establishes a positive relation between interest rates and expected inflation, for the G7 countries and 45 developing economies. For this purpose, we estimate a version of the GARCH specification of the hypothesis for all countries included in the sample. We also test the augmented Fisher relation by including the inflation uncertainty in the equation. The simple Fisher relation holds in all G7 countries but in only 23 developing countries. There is a positive and statistically significant relationship between interest rates and inflation uncertainty for six of the G7 and 18 of the developing countries and this relationship is negative for seven developing countries.  相似文献

Economic and social policies vary across countries, reflecting their cultures and shaping them. People in some countries are more loss averse than in others. People in some countries express stronger preferences for income equality than do people in others, and some countries offer stronger safety nets than others do. The cultural dimension of uncertainty avoidance expresses the degree to which people in a country feel uncomfortable with uncertainty and the way a country deals with the fact that the future can never be known. The author finds that uncertainty avoidance is associated with loss aversion. People are more loss averse in the domains of both portfolios and jobs in countries where uncertainty avoidance is high. Moreover, people in countries where uncertainty avoidance is high express stronger preferences for income equality, and social spending in such countries is high. The cultural dimension of power distance expresses the degree to which the less powerful members of a society accept and expect that power is distributed unequally. The author finds that people in countries where power distance is high express weaker preference for income equality, and social spending in such countries is low.  相似文献

There is growing evidence from multi‐country studies indicating that there is a turning point in the relationship between inflation and economic growth beyond which the detrimental effects of high inflation offset the stimulating effects of mild inflation on growth. However, it is not clear whether it is appropriate to assume an identical turning point in the inflation and growth relation across countries at various stages of development. Using a non‐linear specification and the data from four groups of countries at various stages of development, this paper examines the possibility for a family rather than a single inverted U relation across countries at various stages of development. The estimated turning points are found to vary widely from as high as 15% per year for the lower‐middle‐income countries to 11% for the low‐income countries, and 5% for the upper‐middle‐income countries. No statistically detectable, long‐run relationship between inflation and growth is evident for the OECD countries. The results indicate the potential bias in the estimation of inflation–growth nexus that may result from combining various countries at different levels of development. The existence of such a degree of heterogeneity across countries at various stages of development also suggests the inappropriateness of setting a single, uniform numerical policy target applicable to all (developing) countries.  相似文献

The objective of this paper is to assess whether the Ricardian Equivalence Proposition (REP) holds in developing countries. Prima facie, since the REP requires a number of assumptions that might not appear to be satisfied in developing countries, it seems that the REP should not hold. However, the empirical evidence provided so far is mixed. In this paper, the validity of the REP will be tested using panel data for ten developing countries: Burundi, El Salvador, Ethiopia, Honduras, India, Morocco, Nigeria, Pakistan, Sri Lanka and Zimbabw1e. The countries were chosen for the availability of data and should reflect the various circumstances of low-income countries. Despite the obvious limitation of the data available and the diversity of the countries, the results provide some tentative support for the REP for developing countries, at least warranting further research.  相似文献

This paper examines the effects of International Monetary Fund (IMF) policy announcements on financial markets worldwide. We investigate reactions from stock, bond, foreign exchange and futures markets and banking and financial companies during the Asian crisis. We explore the impact of IMF bailouts not only on crisis countries, but also on main creditor countries. We study the impact of local governments’ and public responses in crisis countries to account for interaction between the IMF and local parties. We show IMF involvement and local governments’ co-operation actually helps crisis countries but not creditors. We show that in crisis countries, financial markets generally react unfavourably to their governments’ initial demands for IMF assistance, while compliance of the crisis countries with the IMF policy action is commonly perceived as good news. Financial markets in crisis countries react negatively to prolonged negotiations and government actions against IMF policy. Creditor countries’ financial markets are not responsive to IMF actions in crisis countries. We discuss policy implications of findings.  相似文献

This paper uses the sequential panel selection method to examine the convergence of the energy use of 107 countries. It contributes by analyzing the order of convergence and the factors affecting the difference in convergence using improved methods. We provide robust evidence to indicate that seven out of ten countries have been convergent during the period examined, and strong decoupling across countries does not exist. Additionally, high-income and upper-middle-income countries show convergence characteristics earlier than lower middle-income and low-income countries. This means that high-income and upper-middle-income countries are the first to achieve steady-state levels by adjusting their industrial structure and adopting new technologies, and energy exporters have dominant control over energy use. We find that energy-exporting countries converge before energy importers do. These results mean that the energy use of most countries is in accordance with the convergence theory. It also shows that GDP per capita, industrialization level and latitude have great impacts on convergence, especially for industrialization. Our research provides a reference for countries around the world to adjust their energy use policies and to realize a rational flow of energy resources.  相似文献

Real price levels are systematically lower in developing countries than in developed countries. This paper provides time series evidence about the effect of financial development on real price level differences for 40 developing countries. Based on cointegration tests, a long-run equilibrium relationship is found between financial development and real price level differences in 21 countries. In seven countries, financial development "Granger-causes" real price level differentials, while for 19 countries the causality runs in the opposite direction. Country-specific institutional or political-economy differences, typically ignored in cross-section analysis, likely play an important role in real price level differences.  相似文献

Using a recently developed probabilistic approach of a conditional directional distance function, we measure the effect of economic growth on countries’ environmental efficiency in carbon dioxide emissions for a sample of 99 countries over the period of 1980–2010. Our approach directly accounts for the exogenous factors influencing countries’ environmental production; therefore, we do not impose the separability condition on the estimated environmental efficiencies. When examining the entire sample as well as the sample of developed countries, our results reveal an inverted U-shaped relationship between countries’ GDP per capita and environmental efficiency. However, when examining the relationship for the sample of developing countries, the results reveal an N-shaped form. Moreover, our results show that countries ratifying the Kyoto Protocol tend to have higher efficiency scores, implying that their mitigation activity is less costly.  相似文献
