This period is also a time of increased incidence of anxiety and depression, underscoring the importance of understanding biological substrates of behavioral and emotion regulation during adolescence. Developmental changes in the brain in concert with…

The adolescent brain

Adolescence is a developmental period characterized by suboptimal decisions and actions that are associated with an increased incidence of unintentional injuries, violence, substance abuse, unintended pregnancy, and sexually transmitted diseases. Traditional neurobiological and cognitive explanations for adolescent behavior have failed to account for the nonlinear changes in behavior…

Speed limits: orientation and semantic context interactions constrain natural scene discrimination dynamics

The visual system rapidly extracts information about objects from the cluttered natural environment. In 5 experiments, the authors quantified the influence of orientation and semantics on the classification speed of objects in natural scenes, particularly with regard to object-context interactions. Natural scene photographs were presented in an object-discrimination task and pattern…

The dual role of peer groups in executive pay: Relative performance evaluation versus benchmarking

We study the role of peer groups in determining the structure and the total amount of executive compensation. Our analysis is based on a standard agency model in which the agent's reservation utility is related to the peer group used for performance evaluation. Our main result is that the informativeness criterion proposed by Holmström (1979) is neither a necessary nor a…

The Baby Boom and World War II: A Macroeconomic Analysis

We argue that one major cause of the U.S. postwar baby boom was the increased demand for female labor during World War II. We develop a quantitativendynamic general equilibrium model with endogenous fertility and female labor-force participation decisions. We use the model to assess the long-term implications of a one-time demand shock for female labor, such as the one experienced by…

Humankapital, politischer Wandel und langfristige Wirtschaftsentwickung

Seit Mitte der achtziger Jahre hat die neue Wachstumstheorie verstärkt Aufmerksamkeit auf Humankapital als eine Quelle des Wirtschaftswachstumsngelenkt. Neuere empirische Ergebnisse weisen allerdings darauf hin, dass Bildungsinvestitionen nur geringe soziale Externalitäten erzeugen und dass der direkte Beitrag des Humankapitals zum Wirtschaftswachstum relativngering ist. In dieser…

Managed Care Konzepte und Lösungsansätze - Ein internationaler Vergleich aus schweizerischer Sicht

This paper applies the five modified standard criteria generally used in economics for assessing system performances to gauge the contribution of Managed Care to the performance of three health care systems, viz. Germany, the Netherlands and the United States. The maximum contribution of Managed Care to the performance of the health care system is found for the United States and the…

Quantal response equilibria

A quantal response specifies choice probabilities that are smooth, increasing functions of expected payoffs. A quantal response equilibrium has the property that the choice distributions match the belief distributions used to calculate expected payoffs. This stochastic generalization of the Nash equilibrium provides strong empirical restrictions that are generally consistent with…

Abuse of dominance and its effects on economic development

Rules on abuse of dominance are used to find a balance between three objectives: 1) ensuring enough competition between firms in order to force them to be efficient and to compete on merit, 2) allowing a certain degree of profitability so that companies have incentives to become more efficient, and 3) achieving an equal distribution of wealth and business opportunities among…

The Denationalization of Immigration Politics: Is It Happening and Who Benefits?

Many scholars have recently argued that nation-state—centered approaches in comparative sociology and political science are obsolete. In this view, we have entered, or are about to enter, a new “postnational” or “transnational” era characterized by complex and qualitatively new patterns of multilevel governance, in which the nation-state still plays a role, though a drastically…

Welfare States, Political Opportunities, and the Mobilization of the Unemployed: A Cross-National Analysis

This article follows a revised political opportunity approach to argue that mobilization of underprivileged groups is constrained by the political opportunity structures provided by the institutional context of the country in which they act. Contrary to traditional opportunity theories, it is suggested that their mobilization also depends on a set of opportunities specific to the…

Unconditional quantile treatment effects under endogeneity

This paper develops IV estimators for unconditional quantile treatment effects (QTE) when the treatment selection is endogenous. In contrast to conditional QTE, i.e. the effects conditional on a large number of covariates X, the unconditional QTE summarize the effects of a treatment for the entire population. They are usually of most interest in policy evaluations because the results…

Privatization and Changes in the Wage Structure - Evidence from Firm Personnel Records

We investigate the wage effects of privatization using person-level firm-based panel datasets from one privatized and one nonprivatized public sector firm in the same country for the years immediately before and after privatization. Thus, we can analyze the before-after effects of privatization while controlling for individual and time fixed effects and allowing for firm-specific…

Predicting House Prices with Spatial Dependence: Impacts of Alternative Submarket Definitions

We analyze the impacts of alternative submarket definitions when predicting house prices in a mass appraisal context, using both ordinary least squares (OLS) and geostatistical techniques. For this purpose, we use over 13,000 housing transactions for Louisville, Kentucky. We use districts defined by the local property tax assessment office as well as a classification of census tracts…
