A new methodology for financial and insurance operational risk capital estimation is proposed. It is based on using the finite time probability of (non)ruin as an operational risk measure, under a general ruin probability model, according to which operational losses may have any joint (dependent) discrete or continuous distribution, and the function, describing the accumulation of risk capital ...

We consider a tournament between two workers of different abilities who choose both human capital investment and effort. The employer can influence the workers’ behavior by determining the sequence of human capital investments, i.e. the training design. The workers can either invest simultaneously or sequentially with the favorite being the first mover or sequentially with the underdog as first...

This paper shows how policies aimed at insuring health risks and those intended to improve the environment are (and should be) deeply intertwined. In the model economy inspired by recent Chinese experience, pollution raises the likelihood of future, poor health prompting households to save more so as to self-insure against anticipated medical expenses. Increased household saving generates more ...

Along the global trend of economic development, it is often observed rapid industrial transformation accompanied by contitual rural-urban migration. In many developing countries there are yet abundant supplies of “surplus labor.”We construct a small open, dynamic framework to examine how the existence of this large supply of rural, unskilled labor a¤ects trade, urbanization, capital accumulatio...

This paper presents a class of models in which agents may devote part of their nonleisure activities to going to school so as to increase the efficiency units of labor they supply to the firms and the wages they receive. The interaction among the technology of human capital accumulation and agents' preferences will determine endogenously the ec::onomy's rate of growth. Given a constant returns ...

a r t i c l e i n f o JEL classification: E62 H22 O41 Keywords: Two-sector model Human capital Optimal factor tax incidence This paper studies the optimal factor tax incidence in a standard two-sector, human capital-based endoge-nous growth model elucidated by Lucas (1988). Capital income taxes generate dynamic inefficiency for capital accumulation and labor income taxes create dynamic ineffici...

Theory tells us that output, the capital stock and the user cost of capital are cointegrated. From the capital accumulation identity, it also follows that the capital stock and investment have a long-run proportional relationship. This has been used to justify the estimation of investment equations embodying a long-run relation between investment and output, rather than between the capital stoc...

This paper examines the direct, first-rounds impact of two types of remittances—internal and external remittances—on income distribution and asset accumulation in rural Pakistan. Using income decomposition techniques on a threeyear panel household data set, the paper finds that internal remittances have a positive effect on equity and that external remittances have a negative effect. The study ...

This note derives the Golden Rule of capital accumulation in a Chakrabortytype economy, i.e. a two-period OLG economy where longevity is endogenous. It is shown that the capital per worker maximizing steady-state consumption per head is inferior to the Golden Rule capital level prevailing under exogenous longevity. We characterize also the Lifetime Golden Rule, that is, the capital per worker m...
