Free Entry and Social Efficiency under Unknown Demand Parameters

Janjgava, Batlome - Center for Economic Research and Graduate Education and … - 2013

In the paper, I examine free entry in homogeneous product markets and its social efficiency. Previous research on free entry in homogeneous product markets has shown that under Cournot oligopoly with fixed setup costs the free entry equilibrium always delivers excessive entry. In contrast, I...

Learning by disinflating

Barnett, Alina; Ellison, Martin - 2012

Disinflationary episodes are a valuable source of information for economic agents trying to learn about the economy. In this paper we are particularly interested in how policymakers can themselves learn by disinflating. The approach differs from the existing literature, which typically focuses...

Duopoly Competition, Escape Dynamics and Non-cooperative Collusion

Janjgava, Batlome; Slobodyan, Sergey - Center for Economic Research and Graduate Education and … - 2011

In this paper, we study an imperfect monitoring model of duopoly under similar settings as in Green and Porter (1984), but here firms do not know the demand parameters and learn about them over time though the price signals. We investigate how a deviation from rational expectations affects the...

Learning by Disinflating

Ellison, Martin; Ellison, Martin; Barnett, Alina - Department of Economics, Oxford University - 2011

Disinflationary episodes are a valuable source of information for economic agents trying to learn about the economy. This paper is especially interested in how a policymaker can themselves learn by disinflating. The approach differs from the existing literature, which typically focuses on...

Bubbles and crashes: Gradient dynamics in financial markets

Friedman, Daniel; Abraham, Ralph - 2009

Fund managers respond to the payoff gradient by continuously adjusting leverage in our analytic and simulation models. The base model has a stable equilibrium with classic properties. However, bubbles and crashes occur in extended models incorporating an endogenous market risk premium based on...

Escape dynamics: A continuous-time approximation

Kolyuzhnov, Dmitri; Bogomolova, Anna; Slobodyan, Sergey - In: Journal of Economic Dynamics and Control 38 (2014) C, pp. 161-183

We extend a continuous-time approximation approach to the analysis of escape dynamics in economic models with constant … escape dynamics by analytically deriving the most probable escape point and mean escape time. The approximation is tested on … characterizing escape dynamics for economically plausible values of constant gain in the model of CWS when escapes are not rare. We …

Bubbles and crashes: Escape dynamics in financial markets

Friedman, Daniel; Abraham, Ralph - 2007

We develop a financial market model focused on fund managers who continuously adjust their exposure to risk in response to the payoff gradient. The base model has a stable equilibrium with classic properties. However, bubbles and crashes occur in extended models incorporating an endogenous...
