House-purchasing decisions and the possibility of existing homeowners to tap into their housing equity depend decisively on prevailing loan-to-value (LTV) ratios in mortgage markets with borrowing constrained households. Utilizing a smooth transition local projection (STLP) approach, I show that...

n an infinite horizon optimal control problem, the Hamiltonian vanishes at the infinite horizon, when the differential equation is autonomous. The integrand in the integral criterion may contain the time explicitly, but it has to satisfy certain integrability conditions. A generalization of...

Piecewise deterministic control problems are problems involving stochastic disturbance of a special type. In certain situations, in an otherwise deterministic control system, it may happen that the state jumps at certain stochastic points of time. Examples are sudden oil finds, or sudden...

This paper analyzes the main uncertainty of college saving - the child’s ability - in the context of the saving with learning model. The first section develops a dynamic model combining asset accumulation and learning to explain the parents’ forward-looking saving behavior when they are...

In many organizations, productivity relies not just on individual effort but also on group morale, that is, the willingness of co-workers to help each other perform better at work. Relative performance evaluations (RPE) are known to increase individual work morale but may negatively affect group...

Taxpayer nudges - behavioral interventions that aim to increase tax compliance without changing the underlying economic incentives of taxpayers - are used increasingly by governments because of their potential cost-effectiveness in raising tax revenue. We collect about a thousand treatment...

We use Norwegian register data from 1989 to 2002 to estimate the causal effects of programme participation on the transition rate from unemployment to employment,by means of a dependent risks hazard rate model. The separate roles of causality and unobserved heterogeneity are non-parametrically...

Based on a combined register database for Norwegian and Swedish unemployment spells, we use the ‘between-countries-variation’ in the unemployment insurance systems to identify causal effects. The elasticity of the job hazard rate with respect to the benefit replacement ratio is around -1.0...

Building on register data describing monthly labour market status for the whole Norwegian population 1992-95, we estimate grouped competing risk hazard rate models for transitions between employment, unemployment and non-participation. The models impose no parametric restrictions on either...

We use Norwegian micro-data to identify the driving forces behind unemployment spells following temporary- and permanent dismissals. The duration of unemployment spells for permanently dismissed workers is primarily explained by individual resources and economic incentives, while spell-duration...
