This paper derives explicit expressions to simulate theta and gamma for American options using the pathwise derivative method. While the pathwise derivative formulas for delta, rho, and vega of American options have been studied in the literature, no correct explicit results for theta and gamma...

We explore possible effects of a Tobin tax on exchange rate dynamics in a heterogeneous agent model. To assess the impact of the Tobin tax in this framework, we extend the model of De Grauwe and Grimaldi (2006) by including transaction costs and perform numerical simulations. Motivated by the...

This paper considers a paradigm financial markets trades booking and valuation, data subscription and portfolio revaluation system. Traded instruments covered include: spot and forward exchange rates (FX); credit default swaps (CDS); total return swaps (TRS); commodity and bond futures; traded...

We develop a stock-flow-consistent agent-based model that comprises a realistic mechanism of money creation and parametrize it to fit actually observed data. The model is used to make out-of-sample projections of broad money and credit developments under the commencement/termination of foreign...

When a country abandons a fixed, or target zone exchange regime it usually claims that the regime was "fundamentally" sound but that it was undermined by pernicious speculation. The validity of the claim is impossible to assess using only observable data-there always exists a future path of...

This paper provides an exact and computable invariant currency value index (ICVI) which is independent of base currency choice. Thus, given a 1xed set of currencies, the index of a currency will have the same value, regardless of base currency choice. This currency index can be used as an...

After faithfully maintaining a fixed exchange rate and fully convertible currency for almost a decade Argentina still pays higher interest rates on peso denominated debt than on US dollar denominated debt. The interest rate spread is the price of keeping the option to devalue alive. Argentina...

The Central Banks around the world are commonly responsible for their exchange rate policies. During the 1990s it has been clear that the controllability of the exchange rates by the central banks' interventions is limited (McKinnon, 1993). When the underlying monetary reserves are bounded,...

In this paper we 'update' the option implied probability of default (option iPoD) approach recently suggested in the literature. First, a numerically more stable objective function for the estimation of the risk neutral density is derived whose integrals can be solved analytically. Second, it is...
