Wheat in the world food economy: Increasing role in developing countries

Wheat is the oldest and most important of the cereal grains in world food supply. In the last two decades the role of wheat in the world food economy has increased substantially, especially in the developing world. This article describes and analyses the role of wheat and highlights and interprets changes that have occurred in the last two decades of rapid change. The authors analyse, in turn, trends in production, consumption, trade and prices with special emphasis on the developing countries.¹ Finally, the authors speculate on how these trends are likely to be effected by future events.     

Hungary's meat price and trade policies : Conforming to some economic constraints of a socialist country

This paper analyses Hungary's price and trade policies for meat and livestock. Three policy constraints are discussed — the need to control consumer discontent, to provide employment, and to maintain close ties with the Council for Mutual Economic Assistance (CMEA) and the Soviet Union. Of particular interest are Hungary's exports of meat rather than grain, and the impact of policies on large and small producers and on Hungary's dependence on the Soviet market.

The multidimensional effect of financial development on trade in Africa: The role of the digital economy

The issue of how financial development affects international trade has gained much attention in the literature, both theoretical and empirical, without investigating the various transmission channels of financial development on international trade. Significantly, how the digital economy modulates the effects of financial development on trade remains unexplored. Our study addresses these research gaps using panel data from 47 African economies spanning 1990 to 2019. Our findings based on the dynamic system GMM approach show that the direct impacts of financial development and the digital economy have been crucial in driving international trade in Africa in the short and long runs. Second, in the short and long runs, the digital economy serves as a vital channel through which financial development has the most significant impact on trade in Africa. Third, the robustness checks by excluding countries endowed with natural resources in Africa provide robust evidence that digital technology and finance matter for trade. Further, the study discloses an important novelty in that the marginal effects on trade increase when financial development in Africa interacts with the digital economy. In light of these findings, we conclude that policy reforms should focus on policies that encourage the development of the digital economy and its use in the financial sector in Africa.     

The impact of firm cost and market size asymmetries on national mergers in a three-country model

This paper studies the impact of firm cost and market size asymmetries on merger decisions. I consider a model where a small and a large country compete in a third (world) market. Each of the two countries has two firms (with potentially different costs) that supply the domestic market and export to the third market. Merger decisions in the two countries are modeled as a simultaneously move game. The paper finds that firms in the large country have more incentives to merge than firms in the small country. In contrast, the government of the large country has more incentives to block a merger than the government of the small country. Thus, the model predicts that conflicts of interest between governments and firms concerning national mergers are more likely in large countries than in small ones.     

The impact of stocks and flows of organizational knowledge on firm performance: an empirical investigation of the biotechnology industry

The knowledge‐based view of the firm is a recent approach to understanding the relationship between firm capabilities and firm performance. Specifically, this approach suggests that knowledge generation, accumulation and application may be the source of superior performance. Other research has conceptualized organizational knowledge in terms of stocks of accumulated knowledge in the firm and flows of knowledge into the firm. This paper tests the relationship between stocks and flows of organizational knowledge and firm performance in the biotechnology industry. We suggest that a firm’s geographic location, alliances with other institutions and organizations and R&D expenditures are representative of knowledge flows, while products in the pipeline, firm citations and patents are indicative of knowledge stocks. Through factor analysis, we develop an aggregated measure of location from several variables. A regression model suggests that location is a significant predictor of firm performance as are products in the pipeline and firm citations. A major contribution of this investigation is the operationalization of geographic location and its statistically significant link to firm performance. Copyright © 1999 John Wiley & Sons, Ltd.     

GM-free private standards and their effects on biosafety decision-making in developing countries

We provide a comprehensive review of international cases where GM-free private standards set up by food companies in developed countries have influenced biosafety policymaking in developing countries. We find 29 cases where private importers have directly or indirectly affected policy decisions in 21 countries. Most of the cases relate irrational fear of export losses to excessively precautionary decisions. These cases are based on two generally misleading premises: the belief that Europe or Japan represents the only market for exports, and the perception that non-GM segregation is infeasible or prohibitively costly in all situations. Our study also demonstrates the importance of information asymmetries across countries and agents and the role of risk aversion in seemingly irrational decision-making. The combination of these four factors helps us explain why presumed but unproven expected commercial losses still represents a significant impediment to biosafety policymaking in developing countries.     

Information communications technology and economic growth in Sub-Saharan Africa: A panel data approach

This research empirically analyzed the impact of mobile phone and the Internet on per capita income of Sub-Saharan Africa (SSA) for the period of 2006–2015 using a panel data of 40 countries. We have employed the robust two-step system GMM. Results showed that growth in mobile phone penetration has contributed significantly to the GDP per capita of the region after controlling for a number of other variables. A 10% increase in mobile phone penetration results in a 1.2% change in GDP per capita. Therefore, improving access to mobile phones will play a critical role in reducing the poverty level of the region through raising the per capita income of the population.However, the Internet has not contributed to the per capita GDP during the study period. The insignificant impact of the Internet could be due to low penetration of the technology, low ICT skill of Internet users, lack of or insufficient local content on the global network, and the relatively immature state of the technology in the region. Therefore, governments and other stakeholders should design policies that encourage expansion of the Internet. In addition to improving Internet access, policies which focus on ICT skill development and local content creation should also be designed and implemented.     

Effects of data localization on digital trade: An agent-based modeling approach

Post the Snowden and Cambridge Analytica episodes, concerns have been raised by governments and regulators on protecting consumer data collected and transmitted by various digital firms. Driven by concerns of privacy, national security, surveillance, and cyber terrorism, governments around the world have been erecting barriers in cyberspace through data localization. The extent of data localization varies from free flow of data, to stringent restrictions requiring all data to be stored only within the territorial jurisdiction of the country. Though there are certain legitimate concerns regarding protection of personal data, scholars and liberal economists have long proclaimed that any restrictions on the Internet and associated digital trade will have serious economic consequences. Data localization affects digital trade between consumers and producers of digital services to varying degrees. In this paper, we use agent based modeling to study the properties and behaviours of consumers and producers under varying data localization regimes. An augmented gravity model of trade with iceberg coefficient is incorporated to reflect distance-related costs between producers and consumers. Varying data localization compliance costs are included to reflect the effect of non-tariff barriers of data restrictions. Our extensive simulations indicate that there is often clustering of consumers around local firms in highly restrictive data localization regimes, thus enabling local firms to effectively compete against global multinationals. However, results also indicate that while free cross-border data flow enables intense competition amongst producers, data localization restrictions often limit consumer choice due to its effect on price and quality of services.
