After the 2007-08 food crisis, addressing high and volatile cereal prices became a priority for national governments in Sub-Saharan Africa because of their key role in determining consumption and income of poor smallholders. Nevertheless, the lack of information and some misperceptions on the...

We study a series of growth models in which households' preferences display `jealousy' or `external habits': a negative dependence on average consumption. We argue that accounting for consumption externalities in growth models requires consideration of both their static and dynamic effects. In a...

In this paper we propose and estimate an econometric model for the distribution of trading activity across options written on the DAX index. The model is based on the observation that in this market options with strike prices ending on 000, 200, 400, 600 and 800 (the class of 200-strike options)...

We study an overlapping generations model of human capital accumulation with threshold effects using regional data for West Germany. Our basic goal is to shed light on what makes German regions grow. The paper finds that the relative income distribution appears to be stratifying into a trimodal...

This paper proposes structured parametrizations for multivariate volatility models, which use spatial weight matrices induced by economic proximity. These structured specifications aim at solving the curse of dimensionality problem, which limits feasibility of model-estimation to small...

In many multivariate volatility models, the number of parameters increases faster than the cross-section dimension, hence creating a curse of dimensionality problem. This paper discusses specification and identification of structured parameterizations based on weight matrices induced by economic...

An adequate theory of Life Satisfaction (LS) needs to take account of both factors that tend to stabilise LS and those that change it. The most widely accepted theory in psychology - setpoint theory - focussed solely on stability. That theory is now regarded as inadequate since several national...

According to the prospect theory financial investors tend to sell winners too early and ride losers too long. Therefore, demand for financial advise should be high in a bull market and low in a bear market. Thus, we test the hypothesis whether the demand for business magazines is somehow related...
