Insurance and Inequality with Persistent Private Information
We study optimal insurance contracts for an agent with Markovian private information. Our main results characterize the implications of constrained efficiency for long-run welfare and inequality. Under minimal technical conditions, there is Absolute Immiseration: in the long run, the agent?s consumption and utility converge to their lower bounds. When types are persistent and utility is unbounded below, there is Relative Immiseration: low-type agents are immiserated at a faster rate than high-type agents, and ?pathwise welfare inequality? grows without bound. These results extend and ...

Imperfect Information Transmission from Banks to Investors: Macroeconomic Implications
Our goal is to elucidate the interaction of banks' screening effort and strategic information production in loan-backed asset markets using a general equilibrium framework. Asset quality is unobserved by investors, but banks may purchase error-prone ratings. The premium paid on highly rated assets emerges as the main determinant of banks' screening effort. The fact that rating strategies reflect banks' private information about asset quality helps keep this premium high. Conventional regulatory policies interfere with this decision margin, thereby reducing signaling value of high ratings and ...

Imperfect Information Transmission from Banks to Investors: Macroeconomic Implications
We study the interaction of information production in loan-backed asset markets and credit allocation in a general equilibrium framework. Originating banks can screen their borrowers, but can inform investors of their asset type only through an error-prone rating technology. The premium paid on highly rated assets emerges as the main determinant of screening effort. Because the rating technology is imperfect, this premium is insufficient to induce the efficient level of screening. However, the fact that banks know their asset quality and produce ratings accordingly helps keep the premium ...

Why did Rich Families Increase their Fertility? Inequality and Marketization of Child Care
A negative relationship between income and fertility has persisted for so long that its existence is often taken for granted. One economic theory builds on this relationship and argues that rising inequality leads to greater differential fertility between rich and poor. We show that the relationship between income and fertility has ?attened between 1980 and 2010 in the US, a time of increasing inequality, as high income families increased their fertility. These facts challenge the standard theory. We propose that marketization of parental time costs can explain the changing relationship ...

On the Benefits of Currency Reform
Money allows agents to achieve allocations that are not possible without it. How- ever, currency in most economies is a uniform object, and there may be incentive compatible allocations that cannot be implemented with a uniform currency. We show that currency reform, ie, changing the monetary base by replacing one currency with another, is a powerful tool that can enable a planner to achieve his desired allocation. Our monetary mechanism with currency reform is anonymous and features nonlinear pricing of consumption goods and future assets, as observed in practice. Our result suggests that ...

Home Production and Leisure During the COVID-19 Recession
Between the months of February and April of 2020, average weekly market hours dropped by 6.25, meanwhile 35% of commuting workers reported switching to remote work arrangements. In this paper, we examine implications of these changes for the time allocation of different households, and on aggregate. We estimate that home production activity increased by 2.1 hours a week, or 34% of lost market hours, whereas leisure activity increased by 3.8 hours a week. The monthly value of home production increased by $30.83 billion – that is 10.5% of the concurrent $292.61 billion drop in monthly GDP. ...
