Estimating Trait Heritability in Highly Fecund Species
Increasingly, researchers are interested in estimating the heritability of traits for nonmodel organisms. However, estimating the heritability of these traits presents both experimental and statistical challenges, which typically arise from logistical difficulties associated with rearing large numbers of families independently in the field, a lack of known pedigree, the need to account for grou...
متن کاملOptimal Time-Consistent Taxation with Overlapping Generations
The paper analyzes optimal time-consistent taxation in an overlapping generations model with two-period lived households. The government chooses tax rates and borrowing to finance an exogenous stream of expenditures. It cannot commit to future policies, so announced policies that are not time consistent are not credible. Dynamic programming is used to derive Markov-perfect equilibria. In contra...
متن کاملOverlapping Generations Models with Immigration
In this work we develop overlapping generations models (OLG) which explicitly include immigration. In the following, we propose two general equilibrium models. In a first approach, we investigate the effect of a sudden variation in the number of immigrants on the host country to shed light on the welfare effects of immigration for the various generations of the host country’s population. Subseq...
متن کاملCytoplasmic incompatibility in populations with overlapping generations.
Many insects and other arthropods harbor maternally inherited bacteria inducing "cytoplasmic incompatibility" (CI), reduced egg hatch when infected males mate with uninfected females. CI-causing infections produce a frequency-dependent reproductive advantage for infected females. However, many such infections impose fitness costs that lead to unstable equilibrium frequencies below which the inf...
متن کاملInbreeding in populations with overlapping generations.
An inbreeding matrix is defined for populations with overlapping generations. In the short term it can be expressed in terms of a matrix specifying the passage of genes between the different age groups (and sexes) and a diagonal matrix whose elements depend on the number of individuals in each age group. Formulae for the inbreeding effective number are derived using matrix theory. A comparison ...
