Governments borrow funds to finance the excess of cash payments or interest payments over receipts, usually by issuing fixed income debt and index-linked debt. The goal of this work is to propose a stochastic optimization-based approach to determine the composition of the portfolio issued over a series of government auctions for the fixed income debt, to minimize the cost of servicing debt whil...

This paper implements a pricing procedure for commodity options, taking into account the stochastic nature of spot prices, currency exchange rates and convenience yields. Interest rate risk is also mentioned, but is not included in the numerical implementation. The analytic framework is heavily inspired by Miltersen&Schwartz(1998); however, while they allow the interest rate to be stochastic th...

The purpose of the present research is to investigate the effective channels of the monetary transmission mechanism in Iran. To do so, we devised a New Keynesian Dynamic Stochastic General Equilibrium Model. In our model, the different types of nominal rigidities are introduced beside all the related structural equations, which are extracted and linearized around a steady state point. Furthermo...

We show that if policymakers compute the optimal unconstrained interest-rate rule within a Taylor-type class, they may be led to rules that generate indeterminacy and/or instability under learning. This problem is compounded by uncertainty about structural parameters since an optimal rule that is determinate and stable under learning for one calibration may be indeterminate or unstable under le...

The idea of an exogenous money supply—controlled entirely through central bank interventions—was a fundamental tenet of monetarism and New Classical economics. Post Keynesians have developed an extensive literature arguing that the money supply is in fact endogenous—that market forces combine with central banks in establishing the money supply. But Post Keynesians disagree on a related question...

In general, the interest rate is not directly observable in the nancial market. Short term interest rates are quoted in the money market for maturities up to approximately one year, but longer term interest rates are traded only indirectly through the bond market. In this paper the spot interest rate is described by a bivariate stochastic differential equation state space model that gives rise ...

A growing empirical and theoretical literature argues in favor of specifying monetary policy in the form of Taylor-type interest rate feedback rules. That is, rules whereby the nominal interest rate is set as an increasing function of inflation with a slope greater than one around an intended inflation target. This paper shows that because of the zero bound on nominal interest rates, such rules...
