This paper provides a systematic analysis of identification in linear social interactions models. This is both a theoretical and an econometric exercise as the analysis is linked to a rigorously delineated model of interdependent decisions. We develop an incomplete information game that describes individual choices in the presence of social interactions. The equilibrium strategy profiles are li...

In cyclic nucleotide-gated (CNG) ion channels, binding of cGMP or cAMP drives a conformational change that leads to opening of an ion-conducting pore. One region implicated in the coupling of ligand binding to opening of the pore is the C linker region. Here, we used crosslinking of endogenous cysteines to study interregion proximity. We demonstrate that an individual amino acid--C481--in the C...

School shootings are often used in public policy debate as a justification for increased regulation, based on qualitative arguments. However, to date, no effort has been made to find valid quantitative evidence for the claims bolstering the regulation recommendations. In defense of this absence of evidence, it is usually argued that the rarity of such events does not allow the employment of qua...

Extracting an optimal set of parameter values for a MOS device is great importance in contemporary technology is a complex problem. Traditional methods of parameter extraction can produce far from optimal solutions because of the presence of local optimum in the solution space. Genetic algorithms are well suited for finding near optimal solutions in irregular parameter spaces. In this study*, W...

In this paper we study the economic determinants of the joint retirement process of married couples. We propose a tractable dynamic discrete choice model for retirement decisions which allows for non-trivial saving behaviour. We estimate the model on a 1% sample of Danish couples of potential retirement age drawn from a population-based administrative register. The introduction and subsequent r...

This paper examines the effect of lifelong learning on men’s employment and wages. Using data from the British Household Panel Survey, a variant of the mover-stayer model is developed in which hourly wages are either taken from a stationary distribution (movers) or are closely related to the hourly wage one year earlier (stayers). Mover-stayer status is not observed and we therefore model wages...

This paper assesses the impact of product market competition on job instability. Product market competition is measured by the price-cost margin, and job instability is proxied by the intensity of the use of temporary contracts. Using both worker data from the Spanish Labor Force Survey and …rm data from the Spanish Business Strategies Survey, I show that job instability rises with competition....

In this paper, we combine banking and car insurance data to examine the relationship between individual insurance demand and wealth. Controlling for the value of the car, we provide evidence for a positive relationship, suggesting that insurance is a normal good. This result contrasts with the common Decreasing Absolute Risk Aversion (DARA) hypothesis. However, we show that the investment in ri...

In this paper we develop a dynamic discrete-time bivariate probit model, in which the conditions for Granger non-causality can be represented and tested. The conditions for simultaneous independence are also worked out. The model is extended in order to allow for covariates, representing individual as well as time heterogeneity. The proposed model can be estimated by Maximum Likelihood. Granger...

Self-Employment: A Way to End Unemployment? Empirical Evidence from German Pseudo-Panel Data This paper contributes to the policy-relevant question whether self-employment is a way out of (long-term) unemployment. We estimate the relationship between the entry rate into selfemployment and previous (long-term) unemployment on the basis of pseudo-panel data for Germany in the period 1996-2002. Th...
