This paper shows in an experiment that giving rates in a dictator game increase significantly if payments are offered with delay. We hypothesize that a temptation to be selfish may be at play in social preferences. We model this and demonstrate that our model is consistent with much of the...

We provide a theoretical framework to explain the empirical finding that the estimated betas are sensitive to the sampling interval even when using continuously compounded returns. We suppose that stock prices have both permanent and transitory components. The discrete time representation of the...

We study Body Mass Index (BMI) changes among immigrants from Iran, Pakistan, Sri Lanka, Turkey, and Vietnam relative to native Norwegians in Oslo. We assess the effect of acculturation on BMI changes. We hypothesize that acculturation reduces the gap of BMIs between natives and immigrants....

We incorporate long-term defaultable corporate bonds and credit risk in a dynamic stochastic general equilibrium business cycle model. Credit risk ampli¯es aggregate tech- nology shocks. The debt-capital ratio is a new state variable and its endogenous movements provide a propagation mechanism....

This paper investigates whether attacks against Israeli targets help Palestinian factions gain public support. We link individual level survey data to the full list of Israeli fatalities during the period of the Second Intifada (2000-2006), and estimate a flexible discrete choice model for...

The issue addressed in this paper is that of testing for common breaks across or within equations. Our framework is very general and allows integrated regressors and trends as well as stationary regressors. The null hypothesis is that some subsets of the parameters (either regression coecients...

We examine the e¤ect of teenage childbearing on the adult outcomes of a sample of women who gave birth, miscarried or had an abortion as teenagers. Because teens who abort are more favorably selected than the set of teens who become pregnant, teens who miscarry are less favorably selected than...

We study the random Strotz model, a version of the Strotz (1955) model with uncer- tainty about the nature of the temptation that will strike. We show that the random Strotz representation is unique and characterize a comparative notion of \more temp- tation averse." Also, we demonstrate an...

The gender wage gap varies widely across countries and across skill groups within countries. Interestingly, there is a positive cross-country correlation between the unskilled-to-skilled gender wage gap and the corresponding gap in hours worked. Based on a canonical supply and demand framework,...

We demonstrate that wage volatility, measured as the cross-sectional variance of wage changes in PSID data, is counter-cyclical. We quantify this relationship by estimating the re- gression coecient of wage volatility on the national unemployment rate in a multilevel Bayesian model, then...
