We develop a theoretical model that jointly explains optimal choices and happiness. We work with constant elasticity of substitution functions for utility and happiness. Employing a choice framework, individuals are confronted with two options. When there exists a trade-off, we determine...

The anticipation of bad future events reduces currently experienced happiness and it may through this channel elicit detrimental behavioral responses. We explore this idea in the context of endogenous health and aging. We integrate physiological aging into a life-cycle model, calibrate it with...

Higher order risk preferences are well-known for their relation with precautionary saving or portfolio allocation. Theoretically, they are also connected with other important behavior, such as health-related or eco-friendly behavior, but these relations have never been investigated with field...

We study individual demand for COVID-19 antibody tests in an incentivized study on a representative sample of the US population. Almost 2,000 participants trade off obtaining an athome test kit against money. At prices close to zero, 80 percent of individuals want the test. However, this broad...

The relationship income / distance to CBD is basically nonlinear and its form varies a lot across the world. We often consider classic forms such as the typical US city one, where rich people live in the suburbs and the European city where they live downtown. Nevertheless, more complex patterns...

The n total consumers in the market for a particular good are made up of b brown and g green consumers so that b+g=n. The b brown (g green) consumers are not (are) environmentally conscious and hence they prefer to buy a new (remanufactured) good denoted by N and R respectively. By strategically...

We develop a framework for studying how differences in the level and/or dispersion of per-capita income affect trade structure and welfare in a two-country model. Thereby, we embed nonhomothetic preferences into a home-market model with two sectors of production and one input factor. We...

Reproducing the socio-spatial structure of cities is one of the challenges facing the standard urban economics model of Alonso, Muth, Mills (AMM model). In a widely cited paper, Jan K. Brueckner, Jacques-François Thisse and Yves Zenou (1999) asked "Why is central Paris rich and downtown Detroit...

Vegetables play an important role in human nutrition, as they have a high content of nutrients. In the last five years, there has been a tendency to increase the consumption of vegetables among Romanians, this being attributed to the increase of the living standard, but also to the reorientation...

We analyze individuals with heterogeneous time-inconsistent preferences that consume sin goods and make a savings decision. A government may tax the sin good and provide mandatory health insurance. Due to time-inconsistency, the individual sin good and savings choices in ict internalities. Due...
