This paper analyzes the self-identification process and its role in motivation. We build a model of self-confidence where people have imperfect knowledge about their ability, which in most tasks is a complement to effort in determining performance. High self-confidence thus enhances motivation,...

The main contribution of the paper is an attempt to address the selection and growth issues by working, not with cohorts of households, but with cohorts of individuals. The gain from doing so is that we dispose completely of selection associated with household formation, which compro-mises our...

Part I of this chapter briefly reviews the arguments for using consumption rather than income as a measure of living standards and for using it to measure poverty and inequality. It goes on to discuss the principal uses to which consumption data have been put; while the docu-mentation of living...

Under the Economic Growth and Tax Relief Reconciliation Act of 2001, most U.S. taxpayers received a tax rebate between July and September, 2001. The week in which the rebate was mailed was based on the second-to-last digit of the taxpayer's Social Security number, a digit that is effectively...

While this is typically ignored, the properties of the stochastic process followed by aggregate consumption affect the estimates of the costs of fluctuations. This paper pursues two approaches to modelling aggregate consumption dynamics and to measuring how much society dislikes fluctuations,...

This paper introduces a tractable, structural model of subjective beliefs. Since agents that plan for the future care about expected future utility flows, current felicity can be increased by believing that better outcomes are more likely. On the other hand, expectations that are biased towards...

In recent years, in much of the World Bank's operational work as well as in applied research, consumption aggregates constructed from survey data have been used to measure poverty, to analyse changes in living standards, over time, and to assess the distributional impacts of various programs and...

I study the welfare cost of business cycles in a complete-markets economy where some people are more risk averse than others. Relatively more risk-averse people buy insurance against aggregate risk, and relatively less risk-averse people sell insurance. These trades reduce the welfare cost of...
