A note on international migration,non-traded goods and economic welfare in the source country

"This note extends the work of Rivera-Batiz to the case where capital is collectively owned and the decision to emigrate entails both a withdrawal of labor services from the source-country and the surrender of the ownership of capital. In this framework, which seems to have wide real-world relevance for socialist, labor-managed and peasant economies, it is found that emigration helps increase the welfare of the non-migrant. This result, which seems quite robust to its specifications, is exactly the opposite of that of Rivera-Batiz and points to the need for great caution in drawing policy conclusions with regard to issues pertaining to emigration."     

Local public goods, inter-regional transfers and private information

Suppose that the centre wishes to make transfers between member states of a federation to reduce inequality. However, it lacks precise information concerning the cost differences that are responsible for the initial income inequality. We examine the implications of asymmetric information for the design of the transfer scheme. We show that if member states’ inherent cost levels as local public good providers take discrete values, the first best, or ‘complete information’, transfer scheme may or may not violate incentive compatibility. If inherent cost is a continuous random variable, such a scheme certainly violates incentive compatibility. We also explore the possibility of binding participation constraints. In our model, a binding incentive compatibility constraint leads to a reduction in effort devoted to cost reduction, and a binding participation constraint will also lead to a violation of Samuelson's optimality condition for public good provision.     

Consumption externalities and the effects of international income transfers on the global environment

In this paper, we extend the standard model of private provision of public goods by including consumption externalities to characterize a situation in which economic activities pollute the environment. We consider a case in which there are an industrial country which can afford to invest in the environment and a developing country which cannot. Then, we show that international income transfers in both directions can improve the global environmental quality as well as the welfare of each country. We also show that the results have important implications for policies such as official development assistance or the assignment of tradable emission permits.     

On commodity tax harmonization and public goods provision

This paper argues that Pareto improvements based on harmonizing tax reforms expressed in terms of the divergence between actual and optimal tax structures and over/under provision of public goods require the use of ‘pseudo-optimal’ taxes instead of optimal ones. ‘Pseudo-optimal’ taxes are defined as those obtained using the optimal tax formulas but evaluated at any arbitrary initial tax structure. Within this context the paper reconfirms existing results showing that tax harmonization emerges as a strong policy instrument in achieving a potential Pareto-improvement.     

Federal transfers, environmental policy and economic growth

We study the effects of commonly used cross-country transfer programs on uncoordinated national environmental policies, economic growth and natural resources in a federal economy. Natural resources are a federation-wide public good. In each member country, production degrades the environment, but clean-up policy can improve it. Clean-up policy is financed by taxes on polluting firms’ output and cross-country redistributive transfers. We solve for a symmetric Nash equilibrium among national governments. Transfer policies that lead to higher pollution taxes make existence harder, and are harmful not only to growth but also to the environment. The best way to improve environmental quality is to implement a taxation system that stimulates growth and broadens tax bases to finance national clean-up policies.     

Monopoly,intermediate goods and the pure theory of international trade

Conclusion In a model with two traded good sectors between which intersectoral flows of intermediate goods are allowed and with a monopolized non-traded good sector, the wage rate in terms of two traded goods increases and the rental of capital in terms of two traded goods decreases when the price of relatively more labor intensive traded good sector increases, though nothing definite can be said about the direction of change in the wage rate and rental in terms of the non-traded good. When prices of traded goods are kept constant and labor and/or capital increase(s), output of the non-traded good sector increases provided that the non-traded good is not inferior, having income elasticity of demand less than unity. The factor intensity condition for the traded goods is in general not sufficient for the validity of the Rybczynski theorem to hold with respect to net outputs of the traded goods. We have derived sufficient conditions for the magnification effect to be observed with respect to net outputs of the traded good sectors. Specifically, we have shown that the factor intensity condition (23) is sufficient for the magnification effect to prevail when only labor increases.     

Unilateral capital transfers, public investment, and economic growth

We contrast the effects of a transfer tied to investment in public infrastructure from a traditional pure transfer. The latter has no growth or dynamic consequences; it is always welfare improving, the gains increasing with the stock of government debt and the benefits of debt reduction. A tied transfer generates dynamic adjustments, as public capital is accumulated in the recipient economy. Its long-run growth and welfare effects depend upon the initial stock of infrastructure, as well as co-financing arrangements. These contrasts also apply to temporary transfers, particularly the transitional dynamics. A temporary pure transfer has only modest short-run growth effects and leads to a permanent deterioration of the current account, while a productive transfer has significant impacts on short-run growth, leading to permanent improvements in key economic variables including the current account.     

Habit persistence and the structure of international commodity trade

The paper analyzes the commodity structure of exports and imports of nine industrialized countries, using a dynamic version of the Linear Expenditure System. The hypothesis implied by this approach is that the structure of commodity trade can be explained by a combination of habit persistence and constant marginal expenditure shares. Application of the model to the trade composition of nine countries shows that there are considerable differences in the strength of habit persistence across countries and across commodity groups as well as between exports and imports. These are crucial for the explanation of the associated expenditure and price elasticities.     

Mixed public goods,consumption externality,and economic growth

Conclusion From the viewpoint of pure theory the basic contribution of this paper is in identifying both the consumption inducing and consumption displacing tendencies when mixed public goods are financed by income taxes. We have come to recognize that the provision of mixed public goods is conducive to economic growth if they are consumption displacing in nature.     

Standardization of intermediate goods and international trade

Abstract.  This paper analyzes the relationship between standardization of intermediate inputs and international trade. We employ a two-country, general equilibrium model with differentiated manufacturing goods. Production of manufacturing goods requires specific intermediate inputs, which can be either specialized or standardized. Standardization and the pattern of trade are determined endogenously in our model. In this framework we derive the effects of trade integration, that is, a decline in trading costs for intermediate goods, on the equilibrium outcome.     

International migration,non-traded goods and economic welfare in the source country

"This paper examines the economic effects of emigration in a source country producing both traded and non-traded commodities. It is shown that, even if the economy faces fixed terms of trade, emigration can still affect the welfare of the non-migrants, and the direction of the effect in this context will always be negative." The focus is on migration from developing countries.     

Multinational public goods provision under multilateral income transfers and productivity differences

This article examines multinational public goods provision under multilateral income transfers and productivity differences across countries. Under a planner who uses linear approximation for utility maximization, we show that (1) a country is an income receiver if it has a higher productivity than the average in producing public goods, enabling it to provide more public goods; (2) the amount of transfers can be pinned down for all countries with an adjustment cost; (3) each country obtains an identical utility increment; and (4) the country with the lowest adjustment cost is the best candidate for the planner country. All results are derived based on well-known information regarding the cost of producing the public goods and income levels.     

Private,national and international returns; An application to commodity lending

The article investigates principles of project analysis when investment decisions influence prices and the distribution of income.The first part analyses these problems as they appear to a national policy maker; in the second part, the approach is extended to analyses of the lending policy of an International Lending Agency.     

Bilateral transfers and lending in international environmental cooperation

The paper analyzes environmental lending and transfers in a two country general equilibrium framework. The lender country chooses specific environmental investments which it finances in the neighbour country on the basis of the returns they generate for the lender. The gains from this kind of international environmental financing are illustrated with a numerical calibration of the model showing that the gains to the lender country may be fairly sizable in relation to the expenditure directed currently towards environmental protection. These gains, however, essentially depend on the terms of the environmental financing. We also find that debt-for-nature swaps do not in general produce efficient environmental protection if applied uniformly in international environmental financing.     

Country size and the voluntary provision of international public goods

Standard studies on voluntary contributions to an international public good treat national economies as if they were single agents. This masks the fact that nations are comprised of populations of citizens, whose collective benefits a national government takes account of when deciding on the amount of the contributions. This paper constructs a model which explicitly allows for the effect of population differences and explores their consequences. We can then present the so-called exploitation of the great by the small by Olson and Zeckhauser [Olson, M., Zeckhauser, R., 1966. An economic theory of alliances. Review of Economics and Statistics 48 (1966) 266–279] and explore how residents of larger countries fare relative to those in smaller countries. We also elaborate on the effects of changing populations and show that growing into a large country is not necessarily beneficial for the country's residents.     

Migrants’ international transfers and educational expenditure

The primary objective of this article is to cast some light upon the relationship between education expenditure and the volume of remittances sent to Albania from abroad by international migrants. To assess the existence of an education enhancing effect of remittances, an Engel curve framework is used. In addition, quintile regression analysis is employed to investigate whether migrants’ remittances have a differentiated effect on various quantiles of the conditional distribution of education consumption. The two main empirical findings are that household income has a positive and well‐determined impact on education expenditure, whereas international transfers do not influence education spending.     

Bootstrap testing for cointegration of international commodity prices

This paper investigates cointegration with respect to nine commodity groups traded on international markets. Nonparametric bootstrapping is utilized in the testing procedure. Of the 21 pairs of price series, investigated here, for 13 the no-cointegration null hypothesis is rejected in favour for the cointegration of the series. In addition to five out of the remaining eight cases that were not cointegrated, a plausible explanation is the prevailing trade policy. Thus a great majority of the institutionally nonregulated cases turn out to get empirical support for being cointegrated. An important statistical finding is that the augmented Dickey-Fuller test for cointegration (CRADF) generally yields p-values that are close to the p-values obtained by the bootstrap testing. But once they differ substantially, it is usually an indication of irregular periods (e.g. structural changes) in the series. The paper conducts also a Monte Carlo simulation experiment to investigate the power and size properties of the tests. Generally the results indicate that the test procedures have pretty low power in small samples. Bootstrapping improves the testing somewhat by leading consistently to a bit more powerful inference.     

Network effects,homogeneous goods and international currency choice: New evidence on oil markets from an older era

Conventional wisdom has it that network effects are strong in markets for homogenous goods, leading to the dominance of one settlement currency in such markets. The dominance of the US dollar in global oil markets is said to epitomize this phenomenon. We question this presumption with evidence for earlier periods showing that several national currencies have simultaneously played substantial roles in global oil markets. European oil import payments before and after World War II were split between the dollar and non‐dollar currencies, mainly sterling. Differences in use of the dollar across countries were associated with trade linkages with the United States and the size of the importing country. That several national currencies could simultaneously play a role in international oil settlements suggests that a shift from the current dollar‐based system toward a multipolar system in the period ahead is not impossible.
