Why disagreement may not matter (much) for asset prices

A simple consumption-based two-period model is used to study the (theoretical) effects of disagreement on asset prices. Analytical and numerical results show that individual uncertainty has a much larger effect on risk premia than disagreement if (i) the risk aversion is reasonably high and (ii) individual uncertainty is not much smaller than disagreement. Evidence from survey data...

Asymmetric Dependence Patterns in Financial Time Series

This paper proposes a new copula-based approach to test for asymmetries in the dependence structure of ¯nancial time series. Simply splitting observations into subsamples and comparing conditional correlations leads to spurious results due to the well-known conditioning bias. Our suggested framework is able to circumvent these problems. Applying our test to market data, we...

A dual role for prediction error in associative learning

Confronted with a rich sensory environment, the brain must learn statistical regularities across sensory domains to construct causal models of the world. Here, we used functional magnetic resonance imaging and dynamic causal modelling (DCM) to furnish neurophysiological evidence
that statistical associations are learnt, even when task-irrelevant. Subjects performed an audio-...

Egalitarianism and competitiveness

The article discusses and analyzes data from several economic experiments in a household sur-vey with mothers of preschool children. The researchers measured competitiveness by giving the subjects the choice between competing in a tournament or receiving a piece rate for a real effort task. The subjects also participated in lottery choices, which enabled the researchers to assess...

Austrian Social Security Database

The Austrian Social Security Database (ASSD) is a matched firm-worker data set, which records the labor market history of almost 11 million individuals from January 1972 to April 2007. Moreover, more than 2.2 million firms can be identified. The individual labor market histories are described in the following dimensions: very detailed daily labor market states and yearly earnings at...

Uncertainty Breeds Decreasing Impatience: The Role of Risk Preferences in Time Discounting

Future events are uncertain by their very nature. Therefore, people's risk preferences are likely to play a role in the valuation of allegedly guaranteed future outcomes. We show that future uncertainty conjointly with people's proneness to nonlinear probability weighting generates a unifying framework for explaining many anomalies in intertemporal choice, such as...

The effect of salary caps in professional team sports on social welfare

Increasing financial disparity and spiralling wages in European football have triggered a debate about the introduction of salary caps. This paper provides a theoretical model of a team sports leagues and studies the welfare effect of salary caps. It shows that salary caps will increase competitive balance and decrease overall salary payments within the league. The resulting effect...

New Flight Regimes and Exposure to Aircraft Noise: Identifying Housing Price Effects Using a Ratio-of-Ratios Approach

In October 2003, a new flight regime was introduced at Zurich airport that significantly changed the levels of noise pollution in surrounding communities. We investigate the impact of the new flight policy on apartment prices using a hedonic price model and a non-linear difference-in-differences identification strategy. Our results suggest that rental prices increased by about 3 to 8...

Valuation of electricity swing options by multistage stochastic programming

Electricity swing options are Bermudan-style path-dependent derivatives on electrical energy. We consider an electricity market driven by several exogenous risk factors and formulate the pricing problem for a class of swing option contracts with energy and power limits as well as ramping constraints. Efficient numerical solution of the arising multistage stochastic program requires...

Education, demographics, and the economy

This paper deals with two issues concerning the effects of population
aging on education decisions in the presence of a PAYG pension
system: We first analyze the effects of an aging population per se on
individual skill choices and continuous education and the production
structure. Second, we study the implications of postponed retirement, which is often...

Getting prices right: the impact of the market information service in Uganda

The Market Information Service project in Uganda collected data on prices for the main agricultural commodities in major market centers and disseminated the information through local FM radio stations in various districts. Exploiting the variation across space between households with and without access to a radio, we find evidence suggesting that better-informed farmers managed to...
