A single formula assigns a continuous utility function to every representable preference relation.

Sufficient conditions are provided for a possibly incomplete preference preorder on a topological space to be closed in the product space if and only if it has closed upper and lower contour sets. Notably, it is shown that the two properties are equivalent if the domain of the preorder is a...

To distinguish continuous from discontinuous evolutionary change, a relation of nearness between phenotypes is needed. Such a relation is based on the probability of one phenotype being accessible from another through changes in the genotype. This is exemplified by calculating the shape...

Using a laboratory experiment, we examine whether informal monetary sanctions can lead to better coordination in a repeated minimum effort coordination game. While most groups first experience inefficient coordination, the efficiency increases substantially after introducing an ex post...

Often, a person will become an entrepreneur only after a period of dependent employment, suggesting that occupational choices precede entrepreneurial choices. We investigate the relationship between occupational choice and self-employment. The findings suggest that the occupational choice of...

We argue that entrepreneurial choice proceeds in at least in two steps, with vocational choice nearly always preceding choice of employment status, whether that be self-employment or dependent employment. Since the two decisions are interrelated, analysis of entrepreneurial choice as a single...

We use data on households' deductible choices in auto and home insurance to estimate a structural model of risky choice that incorporates standard risk aversion (concave utility over final wealth), loss aversion, and nonlinear probability weighting. Our estimates indicate that nonlinear...

Utilizing linked vital statistics, administrative employer, and state welfare records, the analysis in this paper investigates the determinants of a woman's intermittent labor force decision at the time of a major life event: the birth of a child. The results indicate that both direct and...

Many firms fail shortly after inception. Yet individuals continue starting businesses. Prewar economists such as Keynes invoked animal spirits and stressed psychological factors in their explanations of economic behavior. Using a large sample obtained from surveys conducted in 18 countries, we...
