For overlapping-generations models with multiple assets and without labour, welfare assessments of equilibrium allocations depend on whether the certainty equivalents of the one-period-ahead marginal rates of return on assets that are held are larger or smaller than the population growth rate....

The paper gives conditions for efficiency and inefficiency of equilibrium allocations in an overlapping-generations model with a constant rate of population growth and with multiple assets, but without labour. Optimal portfolio choice implies that, for any period and history up to that period,...

This expository note uses Hilbert's "infinite hotel", a hotel where one can always find place for another guest even if the hotel is already full, to illustrate the failure of the First Welfare Theorem in "large-square" economies that have infinitely many participants as well as infinitely many...

The paper provides theoretical foundations for models of strategic interdependence under uncertainty that have a continuum of agents and a decomposition of uncertainty into a macro component and an agent‐specific micro component, with a law of large numbers for the latter. This macro-micro...

ECB President Christine Lagarde and others have suggested that climate change creates risks for price stability and for the viability of counterparties to central bank interventions and therefore monetary policy should contribute to fighting climate change. However, pursuit of this new objective...

Die Interpretation des Zinssatzes als Preis ist problematisch. Im Gegensatz zum Preis ist der Zinssatz kein Austauschverhältnis. Modelle, in denen der Zinssatz mit einem Preis für die Nutzung von Kapital identifiziert werden kann, sind sehr speziell. In allgemeineren Modellen sind Zinssatz und...
