World population and food supply: can food production keep pace with population growth in the next half-century?

Criteria for assessing the adequacy of a national average diet are proposed, and the global average cereal production per capita needed to provide an adequate average diet is calculated. The technical feasibility of maintaining global food production per capita up to the year 2050 is assessed. The required input of nitrogen fertilizer is estimated and the water supply in relation to crop evapotranspiration is discussed. It is shown that maintenance of the present global cereal production per capita would be accompanied by a moderate increase in grain consumption per capita in the less-developed countries, but that this will involve a major increase in the net import of grain from the more-developed countries. Achievement of a satisfactory average diet in the less-developed countries as a whole cannot be achieved until the population of this group of countries has declined to a level substantially below its future peak.     

What is the irrigation potential for Africa? A combined biophysical and socioeconomic approach

Although irrigation in Africa has the potential to boost agricultural productivities by at least 50%, food production on the continent is almost entirely rainfed. The area equipped for irrigation, currently slightly more than 13 million hectares, makes up just 6% of the total cultivated area. More than 70% of Africa’s poor live in rural areas and mostly depend on agriculture for their livelihoods. As a result, agricultural development is key to ending poverty on the continent. Many development organizations have recently proposed to significantly increase investments in irrigation in the region. However, the potential for irrigation investments in Africa is highly dependent upon geographic, hydrologic, agronomic, and economic factors that need to be taken into account when assessing the long-term viability and sustainability of planned projects. This paper analyzes the large, dam-based and small-scale irrigation investment potential in Africa based on agronomic, hydrologic, and economic factors. We find significant profitable irrigation potential for both small-scale and large-scale systems. This type of regional analysis can guide distribution of investment funds across countries and should be a first step prior to in-depth country- and local-level assessment of irrigation potential, which will be important to agricultural and economic development in Africa.     

Mandating front-of-package food labels in the U.S. – What are the First Amendment obstacles?

Front-of-package (FOP) food labels are symbols, schemes, or systems designed to communicate concise and useful nutrition-related information to consumers to facilitate healthier food choices. FOP label policies have been implemented internationally that could serve as policy models for the U.S. However, the First Amendment poses a potential obstacle to U.S. government-mandated FOP requirements. We systematically reviewed existing international and major U.S.-based nutrition-related FOP labels to consider potential U.S. policy options and conducted legal research to evaluate the feasibility of mandating a FOP label in the U.S. We identified 24 international and 6 U.S.-based FOP labeling schemes. FOP labels which only disclosed nutrient-specific data would likely meet First Amendment requirements. Certain interpretive FOP labels which provide factual information with colors or designs to assist consumers interpret the information could similarly withstand First Amendment scrutiny, but questions remain regarding whether certain colors or shapes would qualify as controversial and not constitutional. Labels that provide no nutrient information and only an image or icon to characterize the entire product would not likely withstand First Amendment scrutiny.     

How does population density influence agricultural intensification and productivity? Evidence from Malawi

This article uses nationally representative household-level panel data from Malawi to estimate how rural population density impacts agricultural intensification and household well-being. We find that areas of higher population density are associated with smaller farm sizes, lower real agricultural wage rates, and higher real maize prices. Any input intensification that occurs seems to be going to increasing maize yields, as we find no evidence that increases in population density enable farmers to increase gross value of crop output per hectare. We also find evidence that households in more densely populated areas increasingly rely on off-farm income to earn a living, but there appears to be a rural population density threshold beyond which households can no longer increase off-farm income per capita.     

How does population density influence agricultural intensification and productivity? Evidence from Ethiopia

This study uses household-level panel data on smallholder farmers in Ethiopia to estimate how rural population density (RPD) affects agricultural intensification and productivity. Our results suggest that higher RPD is associated with smaller farm sizes, and has a positive effect on input demand, represented by increased fertilizer use per hectare. Overall, increased input use does not lead to a corresponding increase in staple crop yields, and thus farm income declines as population density increases. This suggests a situation where farmers in areas of high RPD may be stuck in place, unable to sustainably intensify in the face of rising RPD and declining farm sizes.     

China's information superhighway: What is it and who controls it?

This paper focuses on China's telecommunications sector from a national perspective, and summarizes the structure of the country's information superhighway. It then analyzes the changing regulatory and policy framework, and the competition among current and potential players in the market. This leads to a final discussion on the implications and likely outcome - who will control the superhighway in China.     

Personalized pricing and advertising: Who are the winners?

This paper investigates who wins and who loses when firms depart from a mass advertising/uniform pricing strategy (benchmark model) to a targeted advertising/price discrimination one. Considering a duopoly market in which firms simultaneously compete in prices and advertising decisions, we examine the competitive and welfare effects of personalized pricing with targeted advertising by comparing equilibrium outcomes under customized advertising/ pricing decisions to the results arising under mass advertising and uniform pricing. We show that, when both firms compete in both market segments, all segment consumers are expected to pay higher average prices under the personalized advertising/pricing strategy. We also show that, in the context of our simultaneous game, targeted advertising with price discrimination might boost firms’ profits in comparison to the case of mass advertising and uniform prices. The overall welfare effects of the personalized strategy are ambiguous. However, even when the personalized strategy boosts overall welfare, consumers might all be worse-off. Thus the paper gives support to concerns that have been raised regarding the firms’ ability to adopt personalized strategies to boost profits at the expense of consumers.     

Competition aspects of pricing access to networks: What are the issues?

The introduction of competition between service providers in industries with some sort of network—such as telecommunications, but also gas and electricity—has created the regulatory problem of access pricing. Where a service provider requires access to a network owned by another firm, how much should that other firm be allowed to charge for access to its network? The problem arises where no agreement is forthcoming through normal market negotiations. The paper discusses the question of access pricing in telecoms, and the issues involved in actually deriving a price fixing mechanism for access to a network.     

Does the growth of mobile markets cause the demise of fixed networks? – Evidence from the European Union

The increasing usage of mobile communication and the declining demand for fixed line telephony in Europe make the analysis of substitutional effects between fixed and mobile networks a key aspect for future telecommunication regulation. Using a unique dataset which contains information on all 27 European Union members from 2003 to 2009, we analyze substitutability between fixed and mobile telecommunication services in Europe by applying dynamic panel data techniques. We find strong empirical evidence for substitution from fixed to cellular networks throughout Europe. In addition, the paper reveals resulting policy implications.     

What Explains the Union Membership Gap between Migrants and Natives?

This article explores the differences in unionization rates between migrant and native‐born workers in 23 European countries. It explores whether individual characteristics or contextual factors explain the variation across countries in the degree of trade unions’ inclusion of migrant workers. The analyses show that individual characteristics cannot explain the variation in the difference between migrant and native unionization rates. Characteristics of the industrial relations regime in the country of destination, in particular the institutional embeddedness of trade unions, affect the likelihood that migrants join trade unions as compared to native workers.     

Who gets the carrot and who gets the stick? Evidence of gender disparities in executive remuneration

This paper offers a new explanation of the gender pay gap in leadership positions by examining the relationship between managerial bonuses and company performance. Drawing on findings of gender studies, agency theory, and the leadership literature, we argue that the gender pay gap is a context‐specific phenomenon that results partly from the fact that company performance has a moderating impact on pay inequalities. Employing a matched sample of 192 female and male executive directors of U.K.‐listed firms, we corroborate the existence of the gender pay disparities in corporate boardrooms. In line with our theoretical predictions, we find that bonuses awarded to men are not only larger than those allocated to women, but also that managerial compensation of male executive directors is much more performance‐sensitive than that of female executives. The contribution of attributional and expectancy‐related dynamics to these patterns is highlighted in line with previous work on gender stereotypes and implicit leadership theories such as the romance of leadership. Gender differences in risk taking and confidence are also considered as potential explanations for the observed pay disparities. The implications of organizations' indifference to women's performance are examined in relation to issues surrounding the recognition and retention of female talent.

Household food security in semi-arid Africa—the contribution of participatory adaptive research and development to rural livelihoods in Eastern Kenya

The already precarious household food-security situation in many semi-arid areas of Africa may be rendered more so through the implementation of structural adjustment programmes that frequently prescribe austerity measures, along with a safety net to protect the vulnerable. However, longer-term development policy perspectives on the one hand, and shorter-term food-relief considerations on the other, often conflict. This paper illuminates the policy conflicts which arise when local-level research and development initiatives interface with the effects of macro-policy-initiated changes and safety-net interventions. Using a participatory agricultural research project in Eastern Kenya as a case study, the paper describes specific household food-security problem diagnosis and a range of research interventions planned within a more sustainable rural livelihoods framework. Working with local farmers, the project implemented a range of applied research and linked development interventions that showed promise in easing food security through a broadening of the livelihood base. Some of these initiatives were carried further through the local farmers' own initiative. The conclusion is that semi-arid areas, despite views that see these as low-potential and obvious safety-net candidates, often have potential for agricultural intensification and increased productivity. However, to ensure that research results are utilised and farmers have access to new technology and markets, there is a need for external or public-sector support to integrated longer-term development initiatives. This may require rethinking the scope of research and development approaches, particularly removing unhelpful boundaries between research, extension and development functions, and increasing farmer participation in the whole process—if possible as part of a less centralised and more household-oriented approach to food-security policy and strategy.     

Is faster better? Quantifying the relationship between broadband speed and economic growth

In this paper, I aim to quantify the relationship between higher broadband speeds (10 Mbps versus 25 Mbps) and the growth rates in important economic outcomes in U.S. counties including jobs, personal income, and labor earnings. Doing so exposes the potential for severe selection bias in studies of broadband's economic impact, which is addressed in this study using Coarsened Exact Matching. Once balanced, the data reveal no economic payoff from the 15 Mbps speed difference between the years 2013 and 2015 (when data is available). I also revisit an early and widely-cited study on broadband's effect on employment to evaluate the possible impacts of selection bias, and conclude that the positive benefits of broadband reported in that particular study are likely spurious. The selection bias problem may infect other studies on the economic impacts of broadband Internet services. Future research on broadband's economic impact should explicitly address selection bias.     

Who are the producers and consumers? Value chains and food policy effects in the wheat sector in Pakistan

We develop a disaggregated Nominal Rate of Assistance (NRA) methodology to disentangle the welfare impacts of policies for various interest groups along the value chain (to disaggregate effects within the “producer” and “consumer” umbrellas). We apply our value chain NRA methodology to the case of Pakistan’s wheat price and trade policy. We analyze the welfare implications for various agents in the wheat-flour value chain from 2000 to 2013, a period characterized by major global price volatility and by regular adjustments of domestic policies. We find that the wheat policy has generally benefitted flour consumers and wheat traders at the expense of wheat farmers, with limited effects on flour millers. Our findings illustrate that the welfare implications of policies can be quite different within the “producer” and “consumer” umbrellas, which has potentially important implications for economic and political economy analyses and for the design of policies that aim to target the poorest groups along value chains.     

What preconceptions and attitudes about engineering are prevalent amongst upper secondary school pupils? An international study

In the Netherlands, as well as in many other countries, there is an increasing interest in implementing education about engineering as a part of general education at the upper secondary school level. In order to know what pupils at that level think about engineering, a study has been done to investigate their attitude towards and their concept of engineering. This study was done not only in the Netherlands but also in 39 other countries. In the preparation of the study, pupils were asked to draw concept maps of what they thought engineering was about. In the quantitative main part of the study, pupils were asked to respond to 33 Likert-type attitude items and 32 concept-items of the same type. A factor analysis was done in order to reveal the dimensions in the pupils’ attitude and concept. In contrast to studies carried out amongst students in lower secondary school levels, a fairly clear concept about engineering was found. The gender differences relating to engineering, found in lower secondary education, were not found in upper secondary education. The prevalent attitude of students towards engineering indicated a fairly positive image of engineering.     

Standing out in the crowd: How unique are the lobbying patterns of the broadcast and wireless industries?

This study examines if, in addition to increasing lobbying expenditure amounts, corporations in the broadcast and wireless industries are also attempting to change lobbying strategies in order to gain competitive advantage. This study examines possible changes in lobbying strategies though the lens of institutional isomorphism, a mechanism of institutional theory. Using institutional isomorphism, the study examines if the broadcast and wireless industries have altered lobbying strategies in the face of competition. This examination is conducted through the construction and analysis of an original data set of lobbying expenditures for the broadcast and wireless industries from 1998 to 2012.     

Where are the Japanese? Japanese information and communications firms in an internetworked world

A decade ago Japanese information and communications (ICT) companies were perceived as posing a significant competitive threat to their Western competitors. Now they are perceived as being in a state of crisis and decline. Have Japanese ICT firms collapsed? Are they to be written off in the global competitive race? This paper examines these questions in two ways: by analysing the strengths and weaknesses of Japanese competencies in the computer, telecommunications equipment, semiconductor, and consumer electronics sectors; and by examining how well they have adapted to the radical change constituted by the emergence of the Internetworked World. Particular attention is paid to the specific case of Japanese consumer electronics and the Sony success story. The paper ends with an examination of the implications of the current crises facing these Japanese firms and their corporate restructuring responses. Several predictions are made regarding the future. The other companies discussed include Fujitsu, Hitachi, Matsushita, NEC, and Toshiba.     

Reducing transatlantic barriers on U.S.-EU agri-food trade: What are the possible gains?

In recent years, the EU and the U.S. have engaged in discussions to lower trade and investment barriers and strengthen transatlantic integration. For food and agricultural trade, non-tariff measures (NTMs) such as sanitary and phytosanitary measures (SPS) stand out as significant barriers. This study combines sector-level econometric modeling with an agriculture-focused computable generable equilibrium (CGE) model to simulate various transatlantic liberalization scenarios on U.S.-EU agri-food trade. The simulations quantify the effect from tariff removal and addressing NTMs. The magnitude of the gains depend upon the level of tariff liberalization, the depth of integration, and possible consumer demand changes.
