Cultural transmission arguably plays an important role in the determination of many fundamental preference traits (e.g., discounting, risk aversion and altruism) and most cultural traits, social norms, and ideological tenets ( e.g., attitudes towards family and fertility practices, and attitudes...

This paper contains the chapters on welfare economics, morality, and the law from a general, forthcoming book, Foundations of Economic Analysis of Law (Harvard University Press, 2003). I begin in chapter 26 with a discussion of the normative foundations of economic analysis, namely, the subject...

We examine how moral sanctions and rewards, notably the moral sentiments involving feelings of guilt and virtue, would be employed to govern individuals' behavior if the objective were to maximize social welfare. In our model, we analyze how the optimal use of guilt and virtue is influenced by...

A long-standing challenge for welfare economics is to develop welfare criteria that can be applied to allocations with different population levels. Such a criterion is essential to resolve the optimal population problem, i.e., the tradeoff between population size and the welfare of each person...

Regulation consists of rulemaking and enforcement. Economic theory offers two complementary rationales for regulating financial institutions. Altruistic public-benefits theories treat rules as governmental instruments for increas- ing fairness and efficiency across society as a whole....

The regulation of many activities depends on whether societies consider them morally controversial or "repugnant". Not only have regulation and related ethical concerns changed over time, but there is also heterogeneity across countries at a given time. We provide evidence of this heterogeneity...

Much of the potential impact of environmental policy is though to come from the incentives it gives firms to develop and introduce new environmental products and processes. Almost all the literature on this issue has focused on the impact of environmental policy on the amount environmental R&D...

The computable general equilibrium models used in the literature tend to be a bit of a black box. This paper provides some intuition behind what goes on in these black boxes by laying out a simple general equilibrium model and intuitively explaining what lies behind the demand for emissions. It...

Carbon control policies in OECD countries commonly differentiate emission prices in favor of energy-intensive industries. While leakage provides a efficiency argument for differential emission pricing, the latter may be a disguised beggar-thy-neighbor policy to exploit terms of trade. Using an...

We discuss global climate mitigation that builds on existing unilateral measures to cut emissions. We document and discuss the rationale for such unilateral measures argue that such measures have the potential to generate positive spillover effects both within and across countries. In a simple...
