Money, liquidity and welfare
This paper develops an analytically tractable Bewley model of money demand to shed light on some important questions in monetary theory, such as the welfare cost of inflation. It is shown that when money is a vital form of liquidity to meet uncertain consumption needs, the welfare costs of inflation can be extremely large. With log utility and parameter values that best match both the aggregate money demand curve suggested by Lucas (2000) and the variance of household consumption, agents in our model are willing to reduce consumption by 3% ~ 4% to avoid 10% annual inflation. The astonishingly ...

The Persistence of Financial Distress.
Using recently available proprietary panel data, we show that while many (35%) US consumers experience fi nancial distress at some point in the life cycle, most of the events of nancial distress are primarily concentrated in a much smaller proportion of consumers in persistent trouble. Roughly 10% of consumers are distressed for more than a quarter of the life cycle, and less than 10% of borrowers account for half of all distress events. These facts can be largely accounted for in a straightforward extension of a workhorse model of defaultable debt that accommodates a simple form of ...

Variety, globalization, and social efficiency
This paper puts recent work on the benefits of variety into the context of a more complete quantitative analysis of the Dixit-Stiglitz-Krugman model of monopolistic competition. We show how the gains from globalization are reflected in the increase in variety and the exploitation of economies of scale, and that the social efficiency question is quantitatively insignificant. These results follow from examining a Bertrand-Nash equilibrium that allows for a finite number of varieties to affect the elasticity of demand facing each firm. We develop a precise expression for per capita real income ...

Why is Trade Not Free? A Revealed Preference Approach
A prominent explanation for why trade is not free is politicians’ desire to protect some of their constituents at the expense of others. In this paper we develop a methodology that can be used to reveal the welfare weights that a nation’s import tariffs implicitly place on different groups of society. Applied in the context of the United States in 2017, this method implies that redistributive trade protection accounts for a significant fraction of US tariff variation and causes large monetary transfers between US individuals, mostly driven by differences in welfare weights across sectors ...

Should I Stay or Should I Go? Inter-state Mobility and Earnings Gains of Young College Graduates
In the late 1990s, nearly 7 percent of young college graduates moved across state lines every year. These workers enjoyed 30 percent higher earnings three years after moving relative to similar stayers, but their gains were not immediate, amounting to only 7 percent in the first year post-move. By the mid-2010s, mobility fell by more than half, and average earnings gains among movers fell and became more front-loaded. At the same time, debt increased among all young college graduates. We propose a model of geographic mobility with incomplete markets, where moving to a new state can deliver ...

The system of national accounts and alternative economic perspectives
Brent Moulton and Nicole Mayerhauser (2015) point out that, for more than 50 years, economists have featured the concept of human capital in their models of labor, growth, productivity, and distribution of income. The authors recommend the addition to the System of National Accounts (SNA) of supplemental person-level accounts: i.e., a System of Person Accounts (SPA). They see this as the best way of recognizing the processes of human capital creation as well as related issues of how income is distributed among individuals and families. The authors argue that this change would support three ...

Optimal taxation and debt with uninsurable risks to human capital accumulation
We consider an economy where individuals face uninsurable risks to their human capital accumulation and study the problem of determining the optimal level of linear taxes on capital and labor income together with the optimal path of the debt level. We show both analytically and numerically that in the presence of such risks it is beneficial to tax both labor and capital income and to have positive government debt.

Labor Market Trends and the Changing Value of Time
During the past two decades, households experienced increases in their average wages and expenditures alongside with divergent trends in their wages, expenditures, and time allocation. We develop a model with incomplete asset markets and household heterogeneity in market and home technologies and preferences to account for these labor market trends and assess their welfare consequences. Using micro data on expenditures and time use, we identify the sources of heterogeneity across households, document how these sources have changed over time, and perform counterfactual analyses. Given the ...

Efficient Public Good Provision in Networks : Revisiting the Lindahl Solution
The provision of public goods in developing countries is a central challenge. This paper studies a model where each agent?s effort provides heterogeneous benefits to the others, inducing a network of opportunities for favor-trading. We focus on a classical efficient benchmark ? the Lindahl solution ? that can be derived from a bargaining game. Does the optimistic assumption that agents use an efficient mechanism (rather than succumbing to the tragedy of the commons) imply incentives for efficient investment in the technology that is used to produce the public goods? To show that the answer is ...
