Second generation human capital benefits of migration

Summary: One important element in estimating the benefits of liberalized migration is the effect on the human capital of migrants' children. Taking human capital benefits of childhood in a developed country into account increases estimates of overall benefits, and may favor permanent migration relative to temporary guest worker programs. I discuss human capital benefits in health, language competence, educational attainment, gender equality, and attachment to location. Benefits are largest and important for immigrants with initially low human capital. Some but not all of these benefits can be attained using retained earnings of temporary migrant workers to help their children at home.

Population ethics and inaccessible populations

Summary: On some views in population ethics, including diminishing marginal value and average views, the value of producing future generations depends on the quantity of beings and welfare in times and places beyond our causal reach. Within these viewpoints large future populations do not automatically have overwhelming moral importance. However, if there are large inaccessible populations, then perspectives like these will-like total utilitarianism and its kin-also place overwhelming weight on the interests of large future populations. Past generations of hominids, and especially of non-human animals, greatly outnumber the current generation, and provide such an inaccessible population. Life elsewhere in the universe might do so as well. Such populations, in addition to changing the recommendations within these theories, may or may not reduce the weight given to the theories in deliberation.

Increasing and improving saving as a philanthropic cause

Summary: While labor's share of world GDP is over one half, capital's share is close to one third. When considering altruistic interventions to increase economic output, as in GiveWell Labs' exploration of U.S. policy, efforts to increase saving and investment should be considered alongside efforts to improve effective labor supply. Compulsory savings schemes and government savings schemes have been used in other developed countries to induce savings far above U.S. levels, and global adoption of such schemes could produce annual gains of many trillions of dollars, although the potential gains are substantially less than the potential gains of labor mobility. Regulatory changes to default pension/investment contributions might also capture important, albeit smaller, gains.

How migration liberalization might eliminate most absolute poverty

Summary: While some estimates that open borders would double gross world product implicitly project the migration of most of the developed country labor force, a much smaller quantity of migration might cut global poverty rates by half or better. The additional income to the poorest required to bring them above extreme poverty lines is in the hundreds of billions of dollars per annum, while doubling world product would approach a hundred trillion dollars of additional annual output. Legal barriers to migration, and blocked desire to migrate, are most extreme for the poorest countries, suggesting extra migrants from those sources. While migrants may receive more income gains than are needed to escape absolute poverty remittances to family, trade, and investment may help to distribute the gains more widely. Overall, the case that migration liberalization for less skilled workers could eliminate most absolute poverty is significantly more robust than the most extreme estimates of global output gains.

What does migration to the United Arab Emirates tell us about labor mobility?

Summary: Some notes on migration to the United Arab Emirates (UAE). As in some other Gulf oil states, e.g. Qatar, almost the entire UAE private sector workforce is composed of foreign guest workers. The ratio of foreign workers to natives is high enough that if achieved by all developed countries it could absorb the labor force of the developing countries. The distribution is dominated by less skilled workers and workers from poor countries, who enjoy much higher wages than at home, but much lower than in countries such as the United States. Emirati tolerance of extremely high immigration may be related to the almost complete insulation of Emirati nationals private labor markets, and the exclusion of migrants from citizenship and access to government revenues. In Dubai, the native population primarily subsists on taxes on the foreign-dominated private sector, enjoying an extremely prosperous standard of living. The UAE shows that truly massive guest worker programs can greatly benefit migrants and natives when politically feasible, and could eventually eliminate most global poverty if broadly imitated.

Migration levies and unskilled labor mobility in Singapore

Summary: Several advocates of increased labor mobility have suggested taxes on migrants to compensate natives of destination countries for any inconveniences and to increase the reward of accepting more migrants, as a theoretical matter. In practice Singapore already accepts an exceptionally large number of unskilled and less skilled temporary workers, taxes them heavily, and uses the extensive net revenue to make a significant contribution to the public accounts. It appears that Singapore captures most of the economic surplus of migration, although migrants also benefit significantly. However, the system produces great local inequality and has a number of other problems that may outweigh fiscal benefits in its political appeal. While Singaporean migration policy seems much better than most developed countries', it is not first-best from a humanitarian point of view, and the model's value in promoting labor mobility elsewhere is uncertain, although intriguing.

What do null fields tell us about fraud risk?

Summary: Efforts to improve scientific integrity must grapple with both questionable research practices that fall within the current "rules of the game" and outright misconduct. Survey and audit data suggest disturbing lower bounds for misconduct, and suggest the possibility of rates high enough to meaningfully distort readings of the scientific literature. The problem could be worse for "null fields" studying nonexistent effects, and for studies that seemingly have top methodological standards. I discuss this analysis in the context of cold fusion and parapsychology, commonly thought to be null fields. These fields may be more at risk of fraud than others, but may also provide a warning about the potential for misconduct in more conventional domains.
