The disjunction effect (DE) refers to an empirical violation of the Sure-Thing Principle (STP), which states that if a person is willing to take an action independently of the outcome of some event, then they must be willing to do so even when the outcome of the event is unknown. A standard...

Efforts to apply economic complexity to identify diversification opportunities often rely on diagrams comparing the relatedness and complexity of products, technologies, or industries. Yet, the use of these diagrams, is not based on empirical or theoretical evidence supporting some notion of...

We model the impact of rising temperatures on labor productivity, labor market dynamics, and income inequality. Using a heterogeneous agent continuous-time (HACT) model with directed search, we analyze how temperature-induced productivity fluctuations influence the labor market, income and wealth...

We propose an asset pricing model featuring time-varying limited participation in both bond and stock markets and household heterogeneity. Households participate in financial markets with a certain probability that depends on their individual income and on asset market conditions. We use indirect...

Helmholtz decompositions break down any vector field into a sum of a gradient field and a divergence-free vector field. Such a result is extended to finite irreducible and reversible Markov processes, where vector fields correspond to anti-symmetric functions on the oriented edges of the underlying...

Animals rely on sensory information from the environment to make optimal decisions. However, animals are often faced with incomplete or ambiguous information. Some species use sensory information and previous experiences to generate expectations about ambiguity. To test this, we used a cognitive...

Two goals that the electricity market should consider are discussed: first, ensuring the optimal dispatching of existing electricity generation at the lowest...

We consider the price-cap regulation of a monopolistic network operator when the regulator has limited commitment. Operating the network requires xed investments and the regulator has the opportunity to unilaterally revise the price cap at random times. When the regulator maximizes consumer surplus...
