We study the effect of dynamic and investment externalities in a one-sector growth model. In our model, two agents interact strategically in the utilization of capital for consumption, savings, and investment in technical progress. We consider two types of investment choices: complements and...

This paper attempts to quantify the private and public economic value of reducing obesity through pharmaceutical and medical interventions. We find that the economic value of such treatments, in particular bariatric surgery, is large for treated patients, with incremental cost-effectiveness...

This paper empirically investigates the following three questions: (i) Do stock returns respond to monetary policy shocks? (ii) Do stock returns alter the transmission mechanism of monetary policy? and (iii) Does monetary policy systematically react to stock returns? Existing research based on...

This paper documents that over the past 25 years, aggregate hourly real wages in the United States have become substantially more volatile relative to output. We use micro-data from the Current Population Survey (CPS) to show that this increase in relative volatility is predominantly due to...

This paper proposes a methodology for testing for whether tax reforms are pro-poor. This is done by extending stochastic dominance techniques to help identify tax reforms that will necessarily be deemed absolutely or relatively pro-poor by a wide spectrum of poverty analysts. The statistical...

This paper proposes tests for stochastic dominance in mobility based on the empirical likelihood ratio. Two views of mobility are considered, either based on measures of absolute mobility or on transition matrices. First-order and second-order dominance conditions in mobility are first derived,...

We provide the first empirical application of a new approach proposed by Lee (2007) to estimate peer effects in a linear-in-means model. This approach allows to control for group-level unobservable and to solve the reflection problem. We investigate peer effects in student achievement in...

We provide a new structural interpretation of the relationship between the slope of the term structure of interest rates and macroeconomic fundamentals. We first adopt an agnostic identification approach that allows us to identify the shocks that explain most of the movements in the slope. We...

This paper examines multidimensional stochastic dominance when one of the indicators of well-being, such as household size or place of residence, is qualitative. It also uses a test for strict dominance based on the empirical likelihood ratio. Empirical applications are based on the DHS...

Research on the effects of informal child fostering arrangements on the welfare of the children involved highlights cross-country disparities. Why may there be differences across countries with regard to the effects of informal child fostering arrangements? If in all countries reporting a high...
