Dynamic products in world exports

The values of three product categories have grown most rapidly in world exports during the period 1980–2000: electrical and electronic goods (including parts and components for such goods), goods from other technology-intensive industries, and labour-intensive products, particularly clothing. A strong geographical concentration at both regional and country levels is discernable regarding the origin of these products from developing countries. There appears to be a sustained movement in world exports towards the growing significance of a limited number of products and it would seem that there has been a rapid and sustained technological upgrading in the export composition of developing countries. However, since the involvement of developing countries is usually limited to the labour-intensive stages in the production process of technology-intensive goods in the context of international production sharing, simple measures of growth in gross export values are poor guides for an assessment of the nature of participation of developing countries in world trade.     

How stable is the demand for money in emerging economies?

One of the key elements of implementing the monetary policy is stability of the demand for money. The literature includes a large number of studies that have tested the stability of the money demand in developed as well as less-developed countries but not in emerging economies of Eastern Europe. As market-based data becomes available from these countries, there is an urgency to test old theories for these modern market-oriented economies. In this article we consider the experiences of Armenia, Bulgaria, the Czech Republic, Hungary, Poland, Russia and the Slovak Republic. Using the bounds testing approach to error-correction modelling and cointegration, we show that money demand is stable in these countries.     

Exact arbitrage, well-diversified portfolios and asset pricing in large markets

For a market with an atomless continuum of assets, we formulate the intuitive idea of a “well-diversified” portfolio, and present a notion of “exact arbitrage”, strictly weaker than the more conventional notion of “asymptotic arbitrage”, and necessary and sufficient for the validity of an APT pricing formula. Our formula involves “essential” risk, one based on a specific index portfolio constructed from factors and factor loadings that are endogenously extracted to satisfy an optimality property involving a finite number of factors. We illustrate how our results can be translated to markets with a large but finite number of assets.     

Is there really a gap between aggregate productivity and technology?

The important contribution by Basu and Fernald (2002 Basu, S and Fernald, JG. 2002. Aggregate productivity and aggregate technology. European Economic Review, 46: 963–91.  [Google Scholar]) shows that, in practice, there is a statistically significant gap between aggregate productivity and technology that can be attributed to inefficient product and labour markets. This is important, as it implies that the Solow residual is an imperfect index for aggregate technology change. We take a related approach and find that when we control for capacity utilization, time varying markup and account for externalities between industries, by employing a superior system estimator, the gap between the aggregate productivity and technology is shown to narrow considerably.     

An Empirical Analysis of the Determinants of Foreign Aid: A Panel Approach

This paper uses a panel approach to examine the determinants of foreign aid. It examines the extent to which taxes on international trade and the scope of government activities, ethnicity, private credit, and education determine foreign aid. The paper specifies and estimates a model that explains the allocation of foreign aid among 151 countries over the period 1975 to 1998. The key empirical finding suggests that Taxes on Trade increases foreign aid dependency. Moreover, trade, private credit, foreign direct investment, GDP per worker, and government consumption are important determinants of foreign aid. The factors that appear to decrease foreign aid include: Years of schooling, private credit, trade, and GDP per worker. The factors that appear to increase foreign aid include: Taxes on international trade, ethnicity, and government consumption.     

The dominant borrower syndrome

The financing channel of a fiscal stimulus matters for the size and the sign of the fiscal multiplier. We develop a general equilibrium model where a fiscal stimulus is partially bank-funded and the government becomes the dominant borrower from banks relative to entrepreneurs. This leads to a negative impact on credit spreads, investment and a contraction in output. We support our story with a structural vector autoregression for a sample of developing countries featuring the dominant borrower syndrome.     

European integration, productivity growth and real convergence

This paper derives a stochastic endogenous growth model to investigate the impact of European Union (EU) integration on convergence and productivity growth. The theoretical model implies both temporary and permanent positive effects of the integration process. The empirical part of the analysis uses structural break tests and data envelopment analysis to examine the accession process of five recent members to the EU15. The results show (i) endogenously identified accession dates as structural breaks, (ii) improved rates of productivity growth after accession over and above the Union benchmark level, and (iii) increased pace of overall growth due to capital accumulation as a result of institutional features of the Union such as Structural and Cohesion Funds. These findings support the theoretical model, implying that economic integration is beneficial for member countries, especially from a long-run perspective, and Cohesion and Structural funds help the new members catch up with the core-EU members’ standard of living.     

Religious Perceptions and Hegemony on Tourism Development: the Case of the Islamic Republic of Iran

This paper highlights tourism development constraints with regard to religious perceptions in a religion‐dominated country, Iran. The ruling class does not want to discount any of the fundamental social and cultural values in the process of preparing strategies for national tourism development plans. Countries such as Iran, concerned about potential negative influences of tourism development, de‐emphasize potential positive economic impacts. In post‐revolutionary Iran, tourism development and promotion follow unique, religiously‐based strategies. The current five‐year development plan is a first step towards a transition to the recognition of the importance of tourism for economic development and improved international relations.

A multi-agent model of a low income economy: simulating the distributional effects of natural disasters

This paper develops an agent-based model of a stylized low income region in order to study the impact of natural disasters on population displacement, income, prices, and consumption with a focus on distributions and coping strategies of low income groups. Key features of the model include the integration of decentralized markets into a full economy in a spatially explicit way and the analysis of short-run adjustment processes. The model is calibrated to a low income region of rural agrarian Pakistan that faced severe floods in 2010. Dynamic adaptation by agents in response to falling income includes migrating and running down savings. Despite these consumption smoothing strategies, some low income groups are vulnerable to starvation. The paper showcases two hypothetical policy scenarios, a cash and a food transfer program, and tracks their effects on the welfare of low income groups in the economy.
