We investigate the effect of discrete sampling and asset price jumps on fair variance and volatility swap strikes. Fair discrete volatility strikes and fair discrete variance strikes are derived in different models of the underlying evolution of the asset price: the Black-Scholes model, the Heston stochastic volatility model, the Merton jump-diffusion model and the Bates and Scott stochastic volatility and jump model.

This paper introduces new variance reduction techniques and computational improvements to Monte Carlo methods for pricing American-style options. For simulation algorithms that compute lower bounds of American option values, we apply martingale control variates and introduce the local policy enhancement, which adopts a local simulation to improve the exercise policy. For duality-based upper bound methods, specifically the primal-dual simulation algorithm, we have developed two improvements.

Four studies investigated whether activating a social identity can lead group members to choose options that are labeled in words associated with that identity. When political identities were made salient, Republicans (but not Democrats) became more likely to choose the gamble or investment option labeled "conservative." This shift did not occur in a condition in which the same options were unlabeled.

Portfolio credit derivatives are contracts that are tied to an underlying portfolio of defaultable reference assets and have payoffs that depend on the default times of these assets. The hedging of credit derivatives involves the calculation of the sensitivity of the contract value with respect to changes in the credit spreads of the underlying assets, or, more generally, with respect to parameters of the default-time distributions. We derive and analyze Monte Carlo estimators of these sensitivities.

Much of the puzzle of underissuance of national bank notes can be resolved for the period 1880–1900 (the period when detailed, bank-level data are available) by disaggregating, taking account of regulatory limits, and considering differences in banks' opportunity costs cross-sectionally and over time. Banks with poor lending opportunities issued more, within regulatory limits. Banks tended to issue more when bond yields (the backing for notes) were high relative to lending opportunities.

Traditional explanations for indirect trade through an entrepot focus on savings in transport costs and the role of specialized agents in processing and distribution. We provide an alternative perspective based on the potential for entrepots to facilitate tariff evasion. Using data on direct exports to mainland China and indirect exports via Hong Kong SAR, we find that the indirect export rate rises with the Chinese tariff rate, despite the absence of any legal tax advantage to sending goods via Hong Kong SAR.

This paper, the second in CEASA's White Paper series on accounting issues, lays out principles under which fair value accounting satisfies the objective of reporting to shareholders. Its "principles-based" approach embraces broad economic concepts but is also pragmatic and specific enough to guide practice.

Raising equity via convertible securities is a roundabout procedure that can lead to erroneous conclusions in the absence of careful evaluation. How can one determine if issuing convertibles is a better alternative to the straight issuance of common equity? In this paper, we attempt to answer this question in the case of Citigroup by estimating the implied common equity price from its $7.5 billion convertible issue and comparing it to a common equity offering. In doing so, we provide a simple procedure for calculating the implied common equity proceeds of convertible issues.
