Missing the Popular Vote: Pitfalls in US Democracy and Reform Proposals

Intereconomics - Only a few years ago, it was a widespread belief that globalisation would trigger processes of democratisation worldwide. However, even old and established democracies such as the...

Direct Democracy and Local Public Finances under Cooperative Federalism

In this paper, we exploit the introduction of the right of local initiatives in the German state of Bavaria in 1995 in order to study the fiscal effects of direct democracy. Our identification strategy combines difference‐in‐differences and regression discontinuity methods: we compare municipal expenditure and revenue between pre‐ and post‐reform periods at population thresholds where the signatures needed to launch initiatives and minimum quorum requirements decrease discontinuously (difference‐in‐discontinuities design). The results suggest that stronger direct democratic institutions lead to an expansion of local government size.     

Geometric Asian option pricing in general affine stochastic volatility models with jumps

In this paper, we present some results on Geometric Asian option valuation for affine stochastic volatility models with jumps. We shall provide a general framework into which several different valuation problems based on some average process can be cast, and we shall obtain closed form solutions for some relevant affine model classes.     

Income and Price Elasticities of Demand in South Africa: An Application of the Linear Expenditure System

This paper investigates the expenditure patterns of South African households using detailed cross‐sectional expenditure and price data that varies across region and time. Linear expenditure system parameter estimates are used to calculate income and price elasticities for a number of product categories at different points of the income distribution. We find substantial variation in the price and income elasticities of demand for items across the income distribution, with the bottom quartile being extremely sensitive to increases in the price of food and clothing items, and the top quartile being as sensitive as households in developed countries.     

Tournament Winner Proportion and its Effect on Effort: An Investigation of the Underlying Psychological Mechanisms

This study investigates the effects of the psychological mechanisms activated by different proportions of tournament winners on effort. Using a real-effort experiment that allows the evolution of social comparison, which is central to our theory, we show that firms can increase employee effort (and performance) by increasing the proportion of winners. Based on a causal model, we generate evidence for our theory that this effect is driven by relative performance concerns and bonus concerns, both of which depend on the proportion of tournament winners. In addition, we find that, over time, the change in effort is more negative the lower the proportion of winners. This effect is driven by the different behaviors of winners and losers in a previous tournament.
