    Immigrant overeducation : evidence from Denmark

    Get PDF
    Anecdotes abound in the Danish public debate about well-educated immigrants that are in jobs they are formally overqualified for. Using a 1995-2002 panel data set based on Danish registers, this study attempts to find out how large a problem immigrant overeducation is in the context of the Danish labor market. More specifically, three questions are posed: First, to what extent are immigrants overeducated and are they more likely to be so than native Danes? Second, why are some immigrants more likely to become overeducated than others? And finally, what are the consequences of overeducation for individual wages? The authors find that among wage earners with at least a vocational education or higher, 25 percent of male non-Western immigrants are overeducated. The same applies for 15 percent of native Danes. Particularly immigrants with a foreign-acquired education risk becoming overeducated - here the share is 30 percent among those with a vocational education or higher. The authors find that Danish labor market experience is extremely important in reducing the likelihood of becoming overeducated. Years spent in the country without accumulating labor market experience do not improve an individual's chances of an appropriate job-to-education match. In terms of earnings consequences, the study concludes that years of overeducation do increase wages for immigrants, but much less so than years of adequate education. This is also true for native Danes, but the relative penalty for overeducation is much larger for immigrants than for Danes.Labor Markets,Population Policies,Access&Equity in Basic Education,Education For All,Teaching and Learning

    Golden Rice and the Looming GMO Trade Debate: Implication for the Poor

    Get PDF
    The first generation of genetically modified crop varieties, currently most widespread in the maize and soybean sectors, sought to increase farmer profitability by improving agronomic traits. The next generation of biotech research is focusing also on breeding for attributes desired by consumers. Although not yet commercially available, a new variety of rice, known as ‘Golden Rice’, has been genetically engineered to contain a higher level of vitamin A. Thus in contrast with the current commercial applications of biotech crops, this new rice variety aims directly at benefiting consumers rather than producers. More specifically, it aims at improving the health of poor people in developing countries who rely on rice as their main staple food (or would be if it was cheaper) and whose diet is nutrient-deficient. This paper analyses empirically the potential economic effects of such an innovation in an environment of heated debates about the risks and benefits of these biotech developments. The emergence of genetically modified foods is generating policy reactions that are delaying the development and adoption of what promises to be a high-payoff technology, particularly for the world’s poor. These policy reactions may lead to trade disputes, in which case the way this GMO issue is addressed in the WTO’s dispute settlement body could have profound implications for poor households in developing countries.GMOs, golden rice, rice policy, WTO agreements, consumer preferences

    This paper analyzes price, production and trade consequences of changing consumer preferences regarding the use of genetically modified organisms (GMOs) in food production. The analytical framework used is an empirical global general equilibrium model, in which the entire food processing chain - from primary crops through livestock feed to processed foods - is segregated into genetically modified (GM) and non-GM lines of production. This model is used to analyze the implications of widespread use of genetically engineered crops in some regions whilst consumers in Western Europe and High- income Asia adopt a critical attitude toward GM foods. Two different representations of consumer preference changes are illustrated: (1) a change in price sensitivity: i.e. consumer demand is less sensitive to a decline in the price of GM foods relative to non-GM varieties, and (2) a structural demand shift: for a given price ratio consumers simply demand less of the GM variety relative to the non-GM variety. This analysis finds that developing countries adjust their trade patterns in response to preference changes in important trading partner countries. Non-GM varieties are diverted to GM-critical regions while GM varieties are sold to countries in which consumers are not sensitive to GM content. Furthermore, the development of segregated GM and non-GM food creates a potential niche market for producers if the non-GM characteristic can in fact be preserved and verified throughout the marketing system at reasonable costs.Genetically modified foods Economic aspects. ,Trade. ,Food production. ,Prices. ,

    Genetic engineering and trade

    Advocates of the use of genetic engineering techniques in agriculture contend that this new biotechnology promises increased productivity, better use of natural resources and more nutritious foods. Opponents, on the other hand, are concerned about potentially adverse implications for the environment and food safety. In response to consumer reactions against genetically modified (GM) foods in some countries - particularly in Western Europe - crop production is being segregated into GM and non-GM varieties. This paper investigates how such changes in the maize and soybean sectors may affect international trade patterns, with particular attention given to different groups of developing countries.Biotechnology. ,Environmental impact analysis. ,Genetic engineering. ,International trade. ,Developing countries. ,Agriculture. ,TMD ,

    Genetically Modified Rice Adoption: Implications for Welfare and Poverty Alleviation

    Get PDF
    The first generation of genetically modified (GM) crop varieties sought to increase farmer profitability through cost reductions or higher yields. The next generation of GM food research is focusing also on breeding for attributes of interest to consumers, beginning with ‘golden rice’, which has been genetically engineered to contain a higher level of vitamin A and thereby boost the health of poor people in developing countries. This paper analyses empirically the potential economic effects of adopting both types of innovation in Asia, including its impact on rice producers and other poor households. It does so using the global economy-wide computable general equilibrium model known as GTAP. The results suggest the very considerable farm productivity gains (even if extended beyond GM rice to include those from adopting other GM grains and oilseeds) could be exceeded by the welfare gains resulting from the potential health-enhancing attributes of golden rice, which would boost the productivity of unskilled workers among Asia’s poor.GMOs, golden rice, consumer preferences, nutritional attributes.

    Social accounting matrices for Vietnam 1996 and 1997

    Get PDF
    This paper documents the construction of social accounting matrices (SAMs) for Vietnam for 1996 and 1997. The data sources used to construct the SAMs include national accounts statistics, government budget data, the official 1996 input-output table, the 19 97/98 Vietnam Living Standards Survey (VLSS), and COMTRADE trade data. The agri- food sectors are particularly well represented in the SAMs: the resulting VIETSAM includes 97 producing sectors with eight agricultural sectors, two agricultural service sector s and 13 food processing industries. In terms of institutional detail, the SAMs include five factors of production (three types of labor distinguished by skill level, one type of capital and one type of land), six household types (distinguished by rural/urban, agricultural/non-agricultural, wage/self-employed), and one account each for enterprises, government, investment/savings and rest-of-world. The rest-of-world account is a purely non-trade-related account that keeps track of financial transfers between Vietnamese institutions and the rest of the world. This is because the innovative feature of this SAM is that is takes detailed account of Vietnam's foreign trade flows. Imports and exports of goods and services are distinguished by trading partner – more specifically, 94 partner countries are identified. The SAM is estimated using a cross-entropy approach, which makes efficient use of all available data whilst at the same time allowing for the incorporation of prior information and constraints.Social accounting Viet Nam. ,Foreign trade. ,Living standards. ,TMD ,

    Elevated Electron Temperatures in the Auroral E Layer Measured With the Chatanika Radar

    An extensive series of spectral measurements has been made in the auroral E region with the Chatanika incoherent scatter radar. Becasue of the small scale length for variations of electron density, temperatures, and ion-neutral collisions we used the operating mode with the best possible range resolution—9 km. About 5% of the time the data exhibited an unusual spectral shape that was most pronounced at 105 and 110 km. Instead of being almost Gaussian with only a small hint of two peaks, the spectra are much wider, with two well-developed peaks. After carefully considering the validity of the measurements and their interpretation, we conclude that the unusual spectra are due to greatly enhanced electron temperatures. At 110 km, the electron temperature may increase from 250 K to 800 K, while the ion temperature remains near 250 K. This enhancement of the electron temperature extends from 99 km to at least 116 km. We show that the temperature increase is too large to be accounted for by auroral particle precipitation, though it coincides in time with ion temperature enhancements at altitudes above 125 km. Because these latter enhancements are believed to be due to joule heating, we deduce that electric fields of 24-40 mV/m are present and that the electrons are moving through the ions and neutrals at speeds of 500-800 m/s. Despite these velocities, we find that joule heating of the electrons also cannot account for the elevated electron temperatures. Several consequences of the elevated electron temperatures are discussed. One is that the rate constants for molecular recombination are reduced. Another is that during periods of significant joule heating, the deduced electron density profile, when fully corrected for temperatures, has a significantly lower peak altitude and greater density than that deduced under the usual assumption of equal electron and ion temperatures. Since conductivities, currents, ionization rates, and differential energy spectra are dependent upon the density profile, care must be taken to account properly for the temperature effects when deriving these quantities
