Based on data from a large-scale computer-based survey among more than 3700 German citizens, this paper empirically disentangles the determinants of the general change of electricity contracts and the specific change to green electricity contracts. Our econometric analysis reveals a strong...

9-ending prices are a dominant feature of many retail settings, which according to the existing literature, is because consumers perceive them as being relatively low. Are 9-ending prices really lower than comparable non 9-ending prices? Surprisingly, the empirical evidence on this question is...

This paper aims to test the microfoundations of consumption models and quantify the macro implications of heterogeneity in consumption behavior. We propose a new empirical method to estimate the sensitivity of consumption to permanent and transitory income shocks for different groups of...

We combine the Critical Cost Efficiency Index and the Houtman Maks Index to evaluate the consistency of subjects in a set of choice data from budgets. We show that by simply allowing subjects for one significant mistake (by removing the worst observation), the mean Critical Cost Efficiency Index...

We examine the causes and policy consequences of strategic (willful) ignorance of risk as an excuse to overengage in risky health behavior. In an experiment on Copenhagen adults, we allow subjects to choose whether to learn the calorie content of a meal before consuming it, and measure their...

9-ending prices, which comprise between 40%–95% of retail prices, are popular because shoppers perceive them as being low. We study whether this belief is justified using scanner price-data with over 98-million observations from a large US grocery-chain. We find that 9-ending prices are higher...

This paper presents two models of consumption for the primary purpose of forecasting consumption expenditure growth in New Zealand. The models, which are consistent with a range of consumption functions including the life-cycle and permanent income hypothesis, are error correction models with...

We estimate marginal propensities to consume from wealth shocks for Italian households in the early part of the Great Recession. Large asset price shocks in 2008 underpin an IV estimator. A euro fall in risky financial wealth resulted in cuts in annual total (non-durable) consumption of...

We use sizeable lottery prizes in Norwegian administrative panel data to characterize households’ marginal propensities to consume (MPCs). Our main contribution is to document how MPCs vary with household characteristics and prize size, and how lottery prizes are spent and saved over time. We...

In health care systems today, including those of Switzerland and the United States, participants do not necessarily see the big picture of lifetime health costs and quality of life, and in many systems consumers and providers lack the incentives to manage preventative and chronic care to...
