While in January 2012, Denmark increased the long-standing tax on sugary soft drinks, the tax was cut byhalf in July 2013 and then completely repealed in January 2014. In this study, we examine whetherincreases and cuts of the soft drink tax lead to similar over- or under-shifting to prices and to similardemand responses. We use longitudinal scanner data of 1,282 Danish households to estimate within-product ...
We study a game in which two firms compete in quality to serve a market consisting of consumers with different initial consideration sets. If both firms invest below a certain quality threshold, they only compete for those consumers already aware of their existence. Above this threshold, a firm is visible to all and the highest quality attracts all consumers. In equilibrium, firms do not choose their ...

“Sin taxes” are high on the political agenda in the global fight against obesity. Ac- cording to theory, they are welfare improving if consumers with low self-control are at least as price responsive as consumers with high self-control, even in the absence of ex- ternalities. In this paper, we investigate if consumers with low and high self-control react differently to sin tax variation. For identification, ...
In an urban economy, the distribution of people and real estate prices depends on the location of the central business district of a city. As distance from the city center increases, both prices and population density diminish, for travel costs increase in terms of time and money. As manufacturing gradually leaves the cities, the importance of consumer amenities as attractors of population to the urban ...
We decompose permanent earnings risk into contributions from hours and wage shocks. To distinguish between hours shocks, modeled as innovations to the marginal disutility of work, and labor supply reactions to wage shocks we formulate a life-cycle model of consumption and labor supply. Both permanent wage and hours shocks are important to explain earnings risk, but wage shocks have greater relevance. ...
Mobile money is an innovation that allows financial transactions to be performed via a cell phone. Even in poor regions of Africa, almost everyone has a cell phone; therefore, mobile money could both contribute to the continent’s economic growth and ensure that no Africans are excluded from access to financial services. However, DIW Berlin data from Uganda show that mobile money is actually used less ...
We conduct a randomized field experiment to study the effects of two financial education interventions offered to small-scale retailers in Uganda. The treatments contrast "active learning" with "traditional lecturing" within standardized lesson-plans. We find that active learning has a positive and economically meaningful impact on savings and investment outcomes, in contrast to insignificant impacts ...
The expansion of renewable energies requires infrastructure investments to at least maintain the stability of electricity grids. Using survey data from residential consumers in Germany and Great Britain, we infer in pecuniary terms the extent to which people are prepared to reward the presence of renewable resources in electricity production and how they trade off this change in the fuel mix against ...
