This paper investigates the identification, the determinacy and the stability of ad hoc, "quasi-optimal" and optimal policy rules augmented with financial stability indicators (such as asset prices deviations from their fundamental values) and minimizing the volatility of the policy interest...

This paper shows that a shift from Ramsey optimal policy under short term commitment (based on a negative-feedback mechanism) to a Taylor rule (based on positive-feedback mechanism) in the new-Keynesian model is in fact a Hopf bifurcation, with opposite policy advice. The number of stable...

This algorithm extends Ljungqvist and Sargent (2012) algorithm of Stackelberg dynamic game to the case of dynamic stochastic general equilibrium models including exogenous forcing variables. It is based Anderson, Hansen, McGrattan, Sargent (1996) discounted augmented linear quadratic regulator....

This paper examines the macroprudential roles of bank capital regulation and monetary policy in a Dynamic Stochastic General Equilibrium model with endogenous financial frictions and a borrowing cost channel. We identify various transmission channels through which credit risk, commercial bank...

We present a two-country model with an enhanced banking sector featuring risky lending and cross-border interbank market frictions. We find that (i) the strength of the financial accelerator, when applied to banks operating under uncertainty in an interbank market, will critically depend on the...

In this paper the stop-waiting strategy of Franz Bruss is set into a simple probabilistic framework and applied to the apple share prices from 1984 to 2013. Within the probabilistic framework a heuristic and a mathematical decision rule using the $\Psi$ function is developed. The results are in...

Where is the most likely position for the last success in n events, if each event has the same probability Pr(A)? What is the probability for the last success? This situation assumes returning successes which is different to the stop waiting problem where a single best event is assumed. We set...

We present the first necessary and sufficient conditions for the existence of a unique perfect-foresight solution, returning to a given steady-state, in an otherwise linear model with occasionally binding constraints. We derive further conditions on the existence of a solution in such models,...

In der einfachen finanzmathematischen Welt herrscht ein konstanter Zinssatz. Wird die Modellwelt hinsichtlich einer nicht flachen Zinsstruktur abgeändert, so sollten die Barwertfaktoren um zwischenzeitliche Zinszahlungen (Zinseszinsen) neutralisiert werden. Die Berechnung der Barwertfaktoren...

The study examines the influence of a selective set of macroeconomic forces on stock market prices in Bangladesh. The Dhaka Stock Exchange All-Share Price Index (DSI) is used to represent the prices in the stock market while deposit interest rates, exchange rates, consumer price index (CPI),...
