We analyze the implications of communitarianism-the tendency of people to organize into separate culturally homogeneous groups-for individual and group inequality in human capital accumulation. We propose a non-cooperative social interactions model where each individual decides how much time to...

In this paper, we examine the consequences of imperfect information on the pattern of transfers from parents to children. Drawing on the theory of mechanism design, we consider a model of family contract with two levels of effort. We prove that equal transfers among children are expected under...

This paper explores the role of marriage when markets are incomplete so that individuals cannot diversify their idiosyncratic labor income risk. Ceteris paribus, an individual would prefer to marry a hedge (i.e. a spouse whose income is negatively correlated with her own) as it raises her...

Yes, subject to concerns about Medicare inefficiencies and potentially self-confirming skepticism. The U.S. social security system-broadly defined to include Medicare-faces significant financial problems as the result of an aging population. But demographic change is also likely to raise...

In a model on population and endogenous technological change, Kremer combines a short-run Malthusian scenario where income determines the population that can be sustained, with the Boserupian insight that greater population spurs technological change and can therefore lift a country out of its...

This paper explores how EU countries can address various challenges (including the aging of the population) affecting their systems of old-age income support. It presents two scenarios illustrating the most important uncertainties surrounding the major developments that affect the pension...

This paper studies within-family decision making regarding investment in income protection for surviving spouses. A change in US pension law (the Retirement Equity Act of 1984) is used as an instrument to derive predictions both from a simple Nash-bargaining model of the household and from the...

The concept of time discounting introduces weights on future goods to make these less valu- able. Famously, both the specic functional form of time discounting and its normative sta- tus are contested. To address these problems, this paper provides a measurement-theoretic framework of...

One of the most cherished propositions in economics is that market competition by and large raises consumer welfare. But whether political competition has similarly virtuous consequences is far less discussed. This paper formulates a model to explain why political competition may enhance...

This paper considers the key problems confronting the Pakistan Planning Commission, briefly examines the essentials of planning for a mixed economy, draws lessons from the experience of countries, both developed and developing, that have formulated and implemented successful plans, and suggests...
