This paper models Corporate Social Responsibility (CSR) as one of the outputs that results from a firm's decisions regarding what and how to produce. The framework developed allows for studying technical efficiency and deriving a system of internal shadow prices to quantify the value of...

This paper explores the question of whether market participants could have or should have anticipated the large increase in foreclosures that occurred in 2007 and 2008. Most of these foreclosures stemmed from loans originated in 2005 and 2006, leading many to suspect that lenders originated a...

This paper takes a skeptical look at a leading argument about what is causing the foreclosure crisis and what should be done to stop it. We use an economic model to focus on two key decisions: the borrower's choice to default on a mortgage and the lender's subsequent choice whether to...

Securitization does not explain the reluctance among lenders to renegotiate home mortgages. We focus on seriously delinquent borrowers from 2005 through the third quarter of 2008 and show that servicers renegotiate similarly small fractions of securitized and portfolio loans. The results are...

Modern macroeconomics empirically addresses economy-wide incentives behind economic actions by using insights from the way a single representative household would behave. This analytical approach requires that incentives of the poor and the rich are strictly aligned. In empirical analysis a...

In an overlapping generations maximization framework with consumers, whose information on uncertain future income realizations is front loaded, a closed form aggregate consumption function with CRRA preferences is derived. To have a closed form solution we assume that consumers solve their...

In this paper we examine the link between wage inequality and consumption inequality using a life cycle model that incorporates household consumption and family labour supply decisions. We derive analytical expressions based on approximations for the dynamics of consumption, hours, and earnings...

I study the labor market risks associated with being self-employed. I document that the self-employed are subject to larger earnings fluctuations than employees and that they frequently transition into unemployment. Given the self-employed are not eligible to unemployment insurance, I analyze...

Various deviations from the Permanent Income consumption model with rational expectations have been discussed in the literature, including loss aversion and liquidity constraints. In the existing literature, these two types of consumption asymmetry are usually considered as mutually exclusive....

In this paper we document significantly steeper declines in nondurable expenditures in the UK compared to the US, in spite of income paths being similar. We explore several possible causes, including different employment paths, housing ownership and expenses, levels and paths of health status,...
