    Notes: Abstract. Early twentieth century observers argued that recent American immigrants were inferior, and in particular less skilled, than the old. I estimate wage equations for 1909 allowing for different effects by nationality and for different characteristics on arrival. I then apply the estimated wage differentials to the immigrant composition to measure the effect of changing composition on immigrant earnings. Finally I ask how immigrant earning power changed relative to that of native Americans. I conclude that immigrant “quality” in terms of earnings did decline due to shifting composition but these effects are very small compared with those reported in studies of the post-second World War period.

    Notes: Abstract During the last 20 years, the existence of rich systems of local knowledge, and their vital support to resource use and management regimes, has been demonstrated in a wide range of biological, physical and geographical domains, such as agriculture, animal husbandry, forestry and agroforestry, medicine, and marine science and fisheries. Local knowledge includes empirical and practical components that are fundamental to sustainable resource management. Among coastal-marine fishers, for example, regular catches and, often, long-term resource sustainment are ensured through the application of knowledge that encompasses empirical information on fish behaviour, marine physical environments, fish habitats and the interactions among ecosystem components, as well as complex fish taxonomies. Local knowledge is therefore an important cultural resource that guides and sustains the operation of customary management systems. The sets of rules that compose a fisheries management system derive directly from local concepts and knowledge of the resources on which the fishery is based. Beyond the practical and the empirical, it is essential to recognise the fundamental socio-cultural importance of local knowledge to any society. It is through knowledge transmission and socialisation that worldviews are constructed, social institutions perpetuated, customary practices established, and social roles defined. In this manner, local knowledge and its transmission, shape society and culture, and culture and society shape knowledge. Local knowledge is of great potential practical value. It can provide an important information base for local resources management, especially in the tropics, where conventionally-used data are usually scarce to non-existent, as well as providing a shortcut to pinpoint essential scientific research needs. To be useful for resources management, however, it must be systematically collected and scientifically verified, before being blended with complementary information derived from Western-based sciences. But local knowledge should not be looked on with only a short-term utilitarian eye. Arguments widely accepted for conserving biodiversity, for example, are also applicable to the intellectual cultural diversity encompassed in local knowledge systems: they should be conserved because their utility may only be revealed at some later date or owing to their intrinsic value as part of the world's global heritage. At least in cultures with a Western liberal tradition, more than lip-service is now being paid to alternative systems of knowledge. The denigration of alternative knowledge systems as backward, inefficient, inferior, and founded on myth and ignorance has recently begun to change. Many such practices are a logical, sophisticated and often still-evolving adaptation to risk, based on generations of empirical experience and arranged according to principles, philosophies and institutions that are radically different from those prevailing in Western scientific circles, and hence all-but incomprehensible to them. But steadfastly held prejudices remain powerful. In this presentation I describe the 'design principles' of local knowledge systems, with particular reference to coastal-marine fishing communities, and their social and practical usefulness. I then examine the economic, ideological and institutional factors that combine to perpetuate the marginalisation and neglect of local knowledge, and discuss some of the requirements for applying local knowledge in modern management.

    Notes: Abstract. This paper uses the data on males and females from the 1989 Legalized Population Survey (LPS), a sample of aliens granted amnesty under 1986 Immigration Reform and Control Act, to analyse English language proficiency and earnings. We use a model of English language proficiency that is based on economic incentives, exposure and efficiency variables that measure the costs and benefits of aquiring English language skills. Consistent with the model, in this sample of former illegal aliens, English language proficiency is greater for those with more schooling, who immigrated at a younger age, who have been in the United States longer, with a more continous stay, and who have less access to other origin language speakers where they live. Earnings are higher by about 8% for men and 17% for women who are proficient in both speaking and reading English, compared to those lacking both skills.

    Notes: Abstract. Using two different measures of relative cohort size – one indicating the size and placement of an individual's own birth cohort, and the other, the ratio of young to prime age adults in the United States in that year – it has been possible to isolate strong effects of the population age structure on wages in the United States over the past thirty-three years. These effects have been strong enough that virtually all of the observed change in the experience premium, and a substantial proportion of the changes in the college wage premium, can be explained by the relative cohort size variables alone. Even changes in the amount of within-group variance in wages appear to be largely a function of changing age structure, and absolute wage levels have been strongly affected by these demographic changes, suggesting that population growth can have positive effects on the economy.

    Notes: Abstract. Young people of working age tend to be particularly prone to labor market inefficiencies that keep their wages excessively high and their employment excessively low. These inefficiencies are usually magnified through unemployment benefit systems. This paper examines how these problems can be tackled through “employment vouchers,” i.e. hiring subsidies or tax breaks for the unemployed. It examines how vouchers to the young unemployed should differ from those to the adult unemployed. The employment vouchers considered here reduce unemployment and impose no cost on the government, since they are financed by the induced fall in government expenditures on unemployment benefits. Among other things, we find that young workers should receive lower vouchers as displacement of the old rises and as deadweight from providing vouchers to the old increases.

    Notes: Abstract. Empirical research on US immigrants is reviewed: their productivity and assimilation; their contribution and use of public services; and their impact on native Americans. I discuss the characteristics of cohorts of immigrants that enter the United States at different times, and then quantify the assimilation of immigrants, typically in terms of economic productivity of immigrants compared with natives. Few have found quantifiable negative effects of immigrants on native wages or unemployment in local labor markets, but a more general equilibrium approach than has been empirically implemented may be needed to draw any conclusions regarding the distributional consequences of immigration.

    Notes: Abstract. This paper uses the 1983 Census of Israel to analyze Hebrew speaking skills and the effects of Hebrew fluency on the earnings of adult male immigrants. Hebrew fluency increases with a longer duration in Israel, the presence of children in the household, marrying after immigration, living in an area in which a smaller proportion speak one‘s mother tongue, a younger age at migration, a higher level of schooling and varies by country of birth. Earnings increase monotonically with the use of Hebrew. Speaking English as a second language is associated with higher earnings, even when country of origin is held constant.
