Proposed by M. Stutzer (1996), canonical valuation is a new method for valuing derivative securities under the risk-neutral framework. It is non-parametric, simple to apply, and, unlike many alternative approaches, does not require any option data. Although canonical valuation has great potential, its applicability in realistic scenarios has not yet been widely tested. This article documents the ability of canonical valuation to price derivatives in a number of settings. In a constant-volatility world, canonical estimates of option prices struggle to match a Black-Scholes estimate based on historical volatility. However, in a more realistic stochastic-volatility setting, canonical valuation outperforms the Black-Scholes model. As the volatility generating process becomes further removed from the constant-volatility world, the relative performance edge of canonical valuation is more evident. In general, the results are encouraging that canonical valuation is a useful technique for valuing derivatives. (C) 2005 Wiley Periodicals, Inc.

We estimate the shape of the distribution of stock prices using data from options on the underlying asset, and test whether this distribution is distorted in a systematic manner each time a particular news event occurs. In particular we look at the response of the FTSE100 index to market wide announcements of key macroeconomic indicators and policy variables. We show that the whole distribution of stock prices can be distorted on an event day. The shift in distributional shape happens whether the event is characterized as an announcement occurrence or as a measured surprise. We find that larger surprises have proportionately greater impact, and that higher moments are more sensitive to events however characterised.

The objective of this study is twofold: first to analyze how the implementation of the EU energy tax policies will affect the EU and its Member States and secondly to analyze how energy tax policies can contribute to climate policy objectives in the enlarged EU.

A tanulmány a Déltengeri Társasággal foglalkozó tanulmány folytatása (Madarász [2011]). A 18. századi brit államadósság szerepéről és kezeléséről szóló modern gazdaságtörténeti értékelések áttekintése után a tanulmány részletesen bemutatja Davenant, Defoe, Bolingbroke, Hume, Wallace, Pinto, Steuart és Smith érvelését a \"közhitel\" lehetséges és szükségszerű gazdasági és politikai hatásairól, a háborús kiadások fedezésének módjairól. Részletesebben tárgyalja Hume és Smith álláspontját a papírpénz és a bankok szerepéről, a pénzmennyiség változásának következményeiről és a skóciai \"szabad\" bankrendszer jellemzőiről. A vita egyik oldalán a közhitelt szükséges, ám veszélyes eszköznek tekintették, amely válságba sodorhatja az országot, és aláássa a politikai szabadságot, a másik vélemény szerint a kereskedő állam adóssága szükséges és előnyös, ösztönzi a gazdaság fejlődését, és kifejezi a polgárok bizalmát a kormányzat iránt. / === / The study, following on from the author s previous work on the history of South Sea Company, focuses on the issue of public debt in 18th-century British economic writings. The first part reviews recent debates among economic historians: how to explain the growing credibility of British governments after 1689. The next details the arguments of some important protagonists in the early modern age - Davenant, Defoe, Bolingbroke, Hume, Wallace, Pinto, Steuart and Smith - on the expected economic and political consequences of an increasing public debt and on the methods of financing wars. This is followed by discussion of the monetary theories of Hume and Smith, notably their views on banks, credit, paper money, the effects of increasing money supply, and the features of free\" Scottish banking system. Two main lines of argument were advanced in the controversies on public debt. Several writers regarded it as a necessary but dangerous instrument that undermines political liberty and can lead the state into financial bankruptcy. Others described it as not only necessary, but advantageous to a commercial nation, by stimulating trade and development and symbolizing the public s confidence in their government.

A reálopciók a döntési rugalmasság megtestesítőiként jelen vannak a vállalatvezetők mindennapjaiban, és cégtől függően jelentős értéket képviselhetnek. Értékelésük a hagyományos diszkontált pénzáramlás módszerekkel csak korlátozottan lehetséges, ezért alternatívaként felmerül a pénzügyi opcióárazás módszertana, amelynek hagyományos változatai az alaptermék alakulásáról geometriai Brown-mozgást feltételeznek. A cikk ezt a feltevést veszi górcső alá a reálopciókra történő alkalmazás szempontjából, és megmutatja, hogy habár önkényesnek tűnhet, valójában nem pusztán egy matematikai szempontból kényelmes megoldás, hanem pénzügyileg is elfogadható feltétel. _______ Real options represent the fl exibility of decision-making, and are thus part of the everyday work of corporate executives, often having great value. Valuing them with the use of traditional Discounted Cash Flow models has limited relevance, therefore arises the alternative methodology of fi nancial option pricing, the traditional versions of which assume that the price of the underlying asset follows Geometric Brownian Motion. The paper examines this assumption from the aspect of real option valuation and shows that although it might seem arbitrary, it is not only a mathematically convenient choice, but also a fi nancially acceptable one.

This thesis investigates the design of optimal tax systems in dynamic environments. The first essay characterizes the optimal tax system where wages depend on stochastic shocks and work experience. In addition to redistributive and efficiency motives, the taxation of inexperienced workers depends on a second-best requirement that encourages work experience, a social insurance motive and incentive effects. Calibrations using U.S. data yield higher expected optimal marginal income tax rates for experienced workers for most of the inexperienced workers. They confirm that the average marginal income tax rate increases (decreases) with age when shocks and work experience are substitutes (complements). Finally, more variability in experienced workers' earnings prospects leads to increasing tax rates since income taxation acts as a social insurance mechanism. In the second essay, the properties of an optimal tax system are investigated in a dynamic private information economy where labor market frictions create unemployment that destroys workers' human capital. A two-skill type model is considered where wages and employment are endogenous. I find that the optimal tax system distorts the first-period wages of all workers below their efficient levels which leads to more employment. The standard no-distortion-at-the-top result no longer holds due to the combination of private information and the destruction of human capital. I show this result analytically under the Maximin social welfare function and confirm it numerically for a general social welfare function. I also investigate the use of a training program and job creation subsidies. The final essay analyzes the optimal linear tax system when there is a population of individuals whose perceptions of savings are linked to their disposable income and their family background through family cultural transmission. Aside from the standard equity/efficiency trade-off, taxes account for the endogeneity of perceptions through two channels. First, taxing labor decreases income, which decreases the perception of savings through time. Second, taxation on savings corrects for the misperceptions of workers and thus savings and labor decisions. Numerical simulations confirm that behavioral issues push labor income taxes upward to finance saving subsidies. Government transfers to individuals are also decreased to finance those same subsidies.
