The value of tradeability
This paper determines the value of asset tradeability in an option pricing framework. In our model, tradeability is valuable since it allows investors to exploit temporary mispricings of stocks. The model delivers several novel insights on the value of tradeability: The value of tradeability is the larger, the higher the pricing efficiency of the market is. Uncertainty increases the...

Does the stork deliver happiness? Parenthood and life satisfaction
This paper examines the relationship between parenthood and life satisfaction using longitudinal data on women from the German Socio-Economic Panel. Previous studies have focused on satisfaction differences between parents and comparable childless adults, mostly finding small and often negative effects of parenthood. These comparisons of ex-post similar individuals are problematic if...

How bulimia nervosa relates to addictive behavior
Using longitudinal data that tracks bulimic behavior among young girls (National Heart, Lung, and Blood Institute Growth and Health Study), we examine (1) whether bulimic behavior is consistent with addiction criteria as stated in the Diagnostic and Statistical Manual of Mental Disorders DSM-IV (APA, 1994); and 2) whether the persistence in bulimia nervosa (BN) reflects tolerance...

A game theoretic foundation of competitive equilibria with adverse selection
We construct a fully specified extensive form game that aptures competitive markets with adverse selection. In articular, it allows firms to offer any finite set of contracts, so that cross-subsidization is not ruled out. Moreover, firms can withdraw from the market after initial contract offers have been observed. We show that a subgame perfect equilibrium always exists and that,...

Under-savers anonymous: evidence on self-help groups and peer pressure as a savings commitment device
We test the effectiveness of self-help peer groups as a commitment device for precautionary savings, through two randomized field experiments among 2,687 microentrepreneurs in Chile. The first experiment finds that self-help peer groups are a powerful tool to increase savings (the number of deposits grows 3.5-fold and the average savings balance almost doubles). Conversely, a...

Detecting informed trading activities in the options markets: Appendix on subprime financial crisis
This appendix extends the empirical results in Chesney, Crameri, and Mancini (2011). Informed trading activities on put and call options are analyzed for 19 companies in the banking and insurance sectors from January 1996 to September 2009. Our empirical findings suggest that certain events such as the takeovers of AIG and Fannie Mae/Freddie Mac, the collapse of Bear Stearns...

Inactivating anterior insular cortex reduces risk taking.
We often have to make risky decisions between alternatives with outcomes that can be better or worse than the outcomes of safer alternatives. Although previous studies have implicated various brain regions in risky decision making, it remains unknown which regions are crucial for balancing whether to take a risk or play it safe. Here, we focused on the anterior insular cortex (AIC),...

Trust and control across three emerging economies
What produces trusting behaviour amongst managers? And how does trusting behaviour influence the exercise of organizational control? This paper attempts to answer these two questions in the context of China, Russia and Vietnam. With the reference to the construct of trust in employment relationships as developed by Tzafrir and Dolan, three dimensions of trust are examined empirically...

Credit supply and monetary policy: identifying the bank balance-sheet channel with loan applications
We analyze the impact of monetary policy on the supply of bank credit. Monetary policy affects both loan supply and demand, thus making identification a steep challenge. We therefore analyze a novel, supervisory dataset with loan applications from Spain. Accounting for time-varying firm heterogeneity in loan demand, we find that tighter monetary and worse economic conditions...

Education and optimal dynamic taxation: The role of income-contingent student loans
We study Pareto optimal tax and education policies when human capital upon labor market entry is endogenous and individuals face wage uncertainty. Though optimal labor distortions are history-dependent, i.e. depend on income and education, simple policy instruments can yield the desired distortions: a single nonlinear labor income tax schedule combined with income-contingent loans....

Cultural transmission and discrimination
Workers can have good or bad work habits. These traits are transmitted from one generation to the next through a learning and imitation process, which depends on parents' investment in the trait and the social environment where
children live. If a suffciently high proportion of employers have taste-based prejudices against minority workers, we show that their prejudices...

Stabilizing the economy: Market design and general equilibrium
We employ laboratory methods to study stability of competitive equilibrium in Scarf's economy (International Economic Review, 1960). Tatonnement theory predicts that prices are globally unstable for this economy, i.e. unless prices start at the competitive equilibrium they oscillate without converging. Anderson et al. (Journal of Economic Theory, 2004) report that in laboratory...

The effectiveness of public sponsored training revisited: The importance of data and methodological choices
As the first, substantive contribution, this paper revisits the effectiveness of two widely used public sponsored training programs, the first one focusing on intensive occupational training and the second one on short-term activation and job entry. We use an exceptionally rich administrative data set for Germany to estimate their employment and earnings effects in the early 2000s....

Multi-tasking and inequity aversion in the linear–exponential–normal moral hazard model
This paper analyzes the impact of wage comparisons among inequity-averse agents on optimal incentive intensities in a linear–exponential–normal moral hazard model with multi-tasking. We consider individual and team production tasks that differ in that only individual production causes wage inequality. If the tasks are substitutes in the agents’ effort cost functions, the principal...

A cautionary note on using industry affiliation to predict income
Many literatures investigate the causal impact of income on economic outcomes, for example in the context of intergenerational transmission or well-being and health. Some studies have proposed to use employer wage differentials and in particular industry affiliation as an instrument for income. We demonstrate that industry affiliation is correlated with fixed individual...

Competition and relational contracts: The role of unemployment as a disciplinary device
When workers are faced with the threat of unemployment, their relationship with a particular firm becomes valuable. As a result, a worker may comply with the terms of a relational contract that demands high effort even when performance is not enforceable by a third party. But can relational contracts motivate high effort when workers can easily find alternative jobs? We examine how...

Reference points in renegotiations: The role of contracts and competition
Several recent papers argue that contracts provide reference points that affect ex post behavior. We test this hypothesis in a canonical buyer-seller relationship with renegotiation. Our paper provides causal experimental evidence that an initial contract has a highly significant and economically important impact on renegotiation behavior that goes beyond the effect of contracts on...

Cumulative prospect theory and mean variance analysis. A rigorous comparison
We compare asset allocations derived for cumulative prospect theory(CPT) based on two different methods: Maximizing CPT along the mean–variance efficient frontier and maximizing it without that restriction. We find that with normally distributed returns the difference is negligible. However, using standard asset allocation data of pension funds the difference is considerable....

Caught in the bulimic trap? Persistence and state dependence of bulimia among young women
Eating disorders are an important and growing health concern, and bulimia nervosa (BN) accounts for the largest fraction of eating disorders. Health consequences of BN are substantial and especially serious given the increasingly compulsive nature of the disorder. However, remarkably little is known about the mechanisms underlying the persistent nature of BN. Using a unique panel...
