We extend the shallow lake model by adding the capital stock of an industry. A government can mitigate the effects of pollution arising from industrial activities by imposing the requirement to abate emissions. Within this framework two scenarios are examined: in the social optimal benchmark, the social planner optimally allocates investment. In the competitive equilibrium, market forces determ...

Social insects offer exciting prospects for ageing research due to the striking differences in lifespan among castes, with queens living up to an order of magnitude longer than workers. A popular theory is that senescence is primarily the result of an accumulation of somatic damage with age, balanced by investment into processes of somatic maintenance. Investigation of these predictions in soci...

This paper examines the design of social investment funds (SIFs) and explores the ways they affect agents’ incentives to propose, select, and implement good projects. Compared with other forms of decentralized service provision, SIFs possess features of administratively delegated authority and deep political devolution. Where existing political institutions fail to deliver assistance to vulnera...

Evolutionary approaches to parental care suggest that parents will not automatically invest in all offspring, and they should reduce or eliminate investment in their children if the costs outweigh the benefits. Lack of paternal or social support will increase the costs born by mothers, whereas infant health problems will reduce the evolutionary benefits to be gained. Numerous studies support th...

Allaz and Vila (1993) argued that forward markets mitigate market power and enhance efficiency. This paper analyzes the implications of forward markets when oligopolistic firms endogenously choose capacity levels. The paper shows that the forward market that occurs after the investment decision is committed may discourage total investment and result in a Pareto-inferior outcome. However, the fo...

sustained is by omitting any reference to the sensation novels thronged with palpably nervous middle-class bodies which gave rise during the 1860s to a fury of indignation. "The reader's nerves are affected like the hero's", Margaret Oliphant stridently complained in a review of the most famous of them all, Wilkie Collins's The woman in white (1860). Such omissions make Nerves and narratives, a...

We introduce social capital accumulation into a neoclassical model, showing how it differs from physical and human capital accumulation. We take the view that social capital is crucial to the enjoyment of socially provided goods and that it is mainly accumulated by means of participation to social activities. Under-investment in social capital may lead a growing economy to fall into a social po...
