| dc.description | This paper studies the law of any power of the integral of geometric Brownian motion over any finite time interval. As its main results, two integral representations for this law are derived. This is by enhancing the Laplace transform ansatz of Yor (1992) with complex analytic methods, which is the main methodological contribution of the paper. The one of our integrals has a similar structure to that obtained by Yor, while the other is in terms of Hermite functions as those of Dufresne (2001). Performing or not performing a certain Girsanov transformation is identified as the source of these two forms of the laws. While our results specialize for exponents equal to 1 to those obtained by Yor, they yield on specialization representations for the exponent equal to minus 1 laws which are markedly different from those obtained by Dufresne. | |
