Trade costs, infrastructure, and dynamics in a global economy
International Journal of Economic Theory, EarlyView.Abstract This study develops a dynamic two‐country model with trade costs linked to international infrastructure stock. With variable markups and firm heterogeneity, the welfare impact of trade costs depends on firms' cost distribution. Governments engage in a dynamic public investment game, leading to multiple steady states. The dynamic equilibrium of

Journal of Fish Biology, EarlyView.Abstract Genomic resources, new microsatellite markers and a novel observation of a fractal pattern in the genetic population structure are presented for curimba, Prochilodus lineatus, a freshwater migratory model species of South America. Our main goals were to investigate the presence of mixed fish stocks and the effects of damming‐induced ...

Interest Rate Pegs and the Reversal Puzzle: On the Role of Anticipation
Journal of Money, Credit and Banking, EarlyView.Abstract We revisit the reversal puzzle: a counterintuitive contraction of inflation in response to an interest rate peg. We show that its occurrence is intimately related to the degree of agents' anticipation. If agents perfectly anticipate the peg, reversals occur depending on the duration of the peg.

Monetary and Macroprudential Policies under Dollar‐Denominated Foreign Debt
Journal of Money, Credit and Banking, EarlyView.Abstract This paper studies monetary and macroprudential policies in a small open economy that borrows from abroad in foreign currency. The model features a novel mechanism in which exchange rate depreciation triggered by a borrowing constraint is amplified through balance of payments adjustments, increasing the real burden of foreign debt and causing ...

Optimal monetary and fiscal policy under discretion in the new Keynesian model: A technical appendix to Great expectations and the end of the Depression [PDF]
, 2005 This paper details the microfoundations of the model presented in Staff Report no. 234, “Great Expectations and the End of the Depression.” It defines the Markov perfect equilibrium formally in the nonlinear model, discusses in some detail the ...

Enhancing Q‐Learning via State‐Space Design for Active Battery Balancing
Battery Energy, Volume 5, Issue 2, March 2026.This study investigates the profound impact of state definition on the efficacy of Q‐learning for active battery balancing in lithium‐ion battery packs. We define and evaluate three distinct state representations—[State 1, 11‐state space definition], [State 2, 27‐state space definition], and [State 3, 81‐state space definition]—within a reinforcement ...

Family Process, Volume 65, Issue 1, March 2026.ABSTRACT This study explored the reciprocal associations between maternal physical discipline and children's externalizing problems across childhood, distinguishing between trait‐like (i.e., between‐person) and state‐like (i.e., within‐person) differences.

The DNA of Calabi–Yau Hypersurfaces
Fortschritte der Physik, Volume 74, Issue 2, February 2026.Abstract Genetic Algorithms are implemented for triangulations of four‐dimensional reflexive polytopes, which induce Calabi–Yau threefold hypersurfaces via Batyrev's construction. These algorithms are shown to efficiently optimize physical observables such as axion decay constants or axion–photon couplings in string theory compactifications.

Dynamic Price Competition with Price Adjustment Costs and Product Differentiation [PDF]
We study a discrete time dynamic game of price competition with spatially differentiated products and price adjustment costs. We characterise the Markov perfect and the open-loop equilibrium of our game.

, 2012 We study a continuous-time game of strategic experimentation in which the players try to assess the failure rate of some new equipment or technology. Breakdowns occur at the jump times of a Poisson process whose unknown intensity is either high or low ...
