We discuss the data available for the TSE 300 and S&P 500 total return indexes. We consider a number of models, including the Wilkie model and regime switching models. We discuss calibration by maximum likelihood and by Markov chain Monte Carlo for the regime switching lognormal model. We then show how to use this model to price and hedge simple segregated fund maturity guarantees. keywords: Re...

We study a model of common value auctions in which bidders’ private information are independently and asymmetrically distributed. We provide two sufficient conditions under which a first-price auction generates higher revenue than a second-price auction (for a selected equilibrium). A necessary condition is given for this revenue-ranking result to hold in general. We illustrate that in a first-...

Financial literacy and cognitive capabilities are convincingly linked to the quality of financial decision-making, influencing savings, stock-picking, and avoidance of outright financial mistakes. Yet, there is little evidence that education intended to improve financial decision-making is successful. Using plausibly exogenous variation in exposure to state-mandated personal finance and mathema...

Duration of an event tends to be underestimated as it becomes temporally distant (Spetch & Wilkie, 1983). The current study investigated this so-called choose-short effect in time and length in order to reevaluate the claim that the choose-short effect is special to temporal memory (Wearden, Parry, & Stamp, 2002). Participants made discrimination judgments in time or length on a pair of line st...

In the absence of investment and dividend payments, the surplus is modeled by a Brownian motion. But now assume that the surplus earns investment income at a constant rate of credit interest. Dividends are paid to the shareholders according to a barrier strategy. It is shown how the expected discounted value of the dividends and the optimal dividend barrier can be calculated; Kummer’s confluent...

Modifying the methods of Z. Adamowicz’s paper Herbrand consistency and bounded arithmetic (Fund. Math. 171 (2002)), we show that there exists a number n such that ⋃ m Sm (the union of the bounded arithmetic theories Sm) does not prove the Herbrand consistency of the finitely axiomatizable theory Sn 3 . From the point of view of bounded arithmetic, the concept of consistency based on Herbrand’s ...

We argue that since allocation mechanisms will not always be in equilibrium, their out-ofequilibrium properties must be taken into account along with their properties in equilibrium. For economies with public goods, we define a simple market-like mechanism in which the strong Nash equilibria yield the Lindahl allocations and prices. The mechanism satisfies critical out-of-equilibrium desiderata...
